The Inner Voice
Kant on Conditionality and God as Cause
Rachel Barney
Kant’s account of the highest good looks like important common ground with
ancient ethical systems. For he holds that the value of happiness is conditional on
its being conjoined with moral virtue in the highest good; and something like this
conditionality thesis, though framed in different terms, is a shared axiom of ancient
thought. The Epicureans, for instance, see virtue as a necessary condition of or means
to happiness (eudaimonia), since only the virtuous person can avoid self-inflicted
pains and minimize unavoidable ones (Letter to Menoeceus 132). Plato argues
repeatedly that non-moral goods depend for their value on virtue or practical
wisdom: only the wise person can actually be benefited by natural goods such as
health, wealth, and power (Meno 87c–89a, Euthydemus 278e–282a). The Republic
supports conditionality from a different direction, arguing that the just person is
necessarily happier than the unjust. Aristotle agrees that the good man is one for
whom non-moral goods are good (EE VIII.3), and further argues that happiness
consists in virtuous activity, though it may be enhanced by non-moral goods (EN I.7).
The Stoics take a harder and simpler line, insisting that living virtuously and living
happily are the same thing, regardless of external circumstance.1 For all these
philosophers, then, happiness, eudaimonia, is contingent on the possession of virtue.
Moreover, one way or another, all these positions meet Adeimantus’ demand to
Socrates in Republic II, the challenge which motivates the central argument of the
Republic. Since the poets praise justice by dwelling on its rewards, Adeimantus
complains, ‘no one has ever adequately described what each [of justice and injustice]
itself does of its own power by its presence in the soul of the person who possesses it,
even if it remains hidden from gods and humans’ (366e).2 So he challenges Socrates
to do exactly that: to show ‘what each itself does, because of its own powers, to
someone who possesses it, that makes injustice bad and justice good’ (367b). So the

thesis vindicated by the ancient systems is not merely that virtue and happiness tend
to coincide: rather, the one is the cause of the other by a mechanism internal to the
human psyche, independent of external contingencies.3
Now Kant emphatically rejects these ancient versions of conditionality, sometimes
in rather acid terms: ‘it must appear strange that philosophers of both ancient and
modern times have been able to find happiness in very just proportion to virtue
in this life (in the world of sense) or at least have been able to convince themselves
of it’ (5:115, cf. 4:442: ‘[the] pretence that well-being always adjusts itself to welldoing is contradicted by experience’).4 His view is that conditionality is empirically
false—so obviously false that only self-deception could get anyone to believe in it.
The reference to philosophers of modern times is presumably to optimistic moralists
like Shaftesbury. Regarding Plato and Aristotle, Kant has remarkably little to say and
the depth of his erudition is uncertain; but his general charge against the ancients
collectively is clear, namely that they did not properly recognize the fundamental
difference between moral and non-moral value (5:64).5 They failed to give moral
value the independence and authority appropriate to it; but they also failed to
recognize that happiness is a very different thing, and travels independently. Here
the Epicureans and Stoics repeatedly figure as a pair of matching case studies
(5:111–12, 5:126–7; Infield 1981, 7). The Epicureans go wrong by reducing virtue
to prudence, and treating it as instrumental to happiness; the Stoics, conversely, must
be reducing happiness to a kind of moralistic self-satisfaction, since they treat it as an
epiphenomenon of virtue.
Interpretation of such criticisms is complicated by the fact that Kant’s happiness
(Glückseligkeit) is a very different thing from ancient eudaimonia—and, as Kant
emphasizes, is not the complete good for a human being. So we might think that the
relevant Kantian successor concept is not happiness, but the highest good, which
after all is how Aristotle introduces and defines eudaimonia in EN I. And since Kant
agrees that this must incorporate moral virtue, one might see here an opening for
reconciliation: perhaps his disagreement with the ancients is just an artefact of
terminological confusion.
But this conciliatory suggestion is misguided. For Kant does not just fail to use the
ancient concept of eudaimonia; he deliberately rejects it as confused.6 Indeed his own
3
Epicurus might seem to be an exception here, since on his view the value of virtue is purely
instrumental; nonetheless, it is a necessary and sufficient condition of happiness (Letter to Menoeceus
132, Principle Doctrines 17, texts 21B and 22B in Long and Sedley 1987).

which finds important common ground with Aristotle.

Part of the problem is that Kant does not bother to state the ancient theories in anything resembling
their own terms. Hence otherwise baffling claims to the effect that they ‘realized that mere happiness could
not be the one highest good’ (Infield 1981, 6); and, of the Stoics, ‘they really left out of the highest good the
second element (personal happiness)’ (5:127). Here ‘happiness’ is used as if it were simply synonymous
with ‘pleasure’ or ‘the satisfaction of inclination’, which can only make nonsense of the ancient views.

conception of happiness can be neatly presented as a point-by-point repudiation of
the Aristotelian one. Happiness is a subjective state, not an objective one; it is
individual and empirically determined, not determined by our universal human
nature; it has to do with pleasure and desire satisfaction, not the fulfilment of our
rationality (nor does it have any special connection to the ‘higher’ rather than the
‘lower’ pleasures); far from being constituted by virtuous activity, it incorporates no
moral component (except insofar as contentment depends, in the case of virtuous
agents, on the consciousness of acting well (5:116–18, cf. 5:38–9)); and it is not the
highest human good.
These contrasts are so complete that they might seem to overshoot, and to end up
supporting the conciliatory suggestion that Aristotle and Kant are simply talking
about two different things. But Kant’s Glückseligkeit and Aristotle’s eudaimonia are
clear theoretical counterparts inasmuch as they share a core functional role: each is
introduced as our natural and necessary end, the hazily grasped collective object of
our everyday self-seeking desires and inclinations. That is what both accounts are
accounts of; and their differences are symptoms of real philosophical disagreement
rather than a terminological mismatch. The grounds of the disagreement are in a way
obvious and in a way obscure: for Kant simply takes it for granted that happiness is to
be understood in individual, subjective, and hedonistic terms. In doing so, I think, he
means to cast himself as very much a modern man—a realistic observer who rejects
any high-minded naivety about the nature of human desire, on the same sort of brute
empirical grounds as he rejects any optimistic delusions about the relation of virtue
to happiness. Be that as it may, it is clear that Kant means to reject not only ancient
conditionality, but the very concept of eudaimonia on which it depends.
And yet, notoriously, Kant in the end reaffirms conditionality on his own terms:
for the highest good is constituted by a necessary relation between happiness and
virtue. My hope in this chapter is to come to an understanding of Kant’s belated
rehabilitation of this ancient thesis, and to see how it is like and unlike its ancient
counterparts (cf. Engstrom 1996). To do so will require working through some
notoriously puzzling moves in Kant’s argument, each the subject of an enormous
scholarly literature; I will skate quickly past a number of interpretative controversies
in order to discuss, rather selectively, the features of his view which directly or
indirectly illuminate his conception of conditionality. I will begin by sketching
Kant’s accounts of happiness and the highest good, and then consider how conditionality—in its Kantian version a normative relation, specifying that happiness
ought to track virtue—comes to be realized in actual proportionality between an
agent’s virtue and her happiness. This involves examining the relevant postulates of
practical reason: why and in what sense must we, according to Kant, suppose the
realization of proportionality to be possible? And second, why must we postulate
God to bring it about? At the end, I will turn to Kant’s claim that the highest good is
the object of our hope; for here, I will argue, is where the radically revisionist nature
of Kantian conditionality can be most clearly seen.

I The Obscure Object of Desire
It is notoriously difficult to integrate Kant’s characterizations of happiness into a
single, coherent conception.7 His starting point, as I’ve noted, is with the idea of a
collective object of our inclinations, given by nature. According to what looks like an
official definition in the second Critique:
Happiness is the condition of a rational being in the world, in whose whole existence
everything goes according to wish and will. It thus rests on the harmony of nature with his
entire end and with the essential determining ground of his will. (5:125)
As such, happiness is naturally the object of our strongest and deepest inclination
(4:399). It is characteristic of rational beings precisely because it is an idea, over and
above the objects of our particular inclinations (5:430). By the same token our desire
for it is a function of self-love rather than our merely animal selves. But it is
nonetheless a given, its pursuit part of our natural endowment (6:7 n., 6:387–8).
As the sum of our inclinations (4:399), happiness consists, it seems, in the
satisfaction of desire: it is what we get when we get the other, more determinate
things we want (cf. A806/B834). But in some contexts Kant readily substitutes talk
of pleasure—particularly when emphasizing the individual, unpredictable character
of both: ‘Where one places his happiness is a question of the particular feeling of
pleasure or displeasure in each man’ (5:25). This substitution is problematic, of
course, since only on the basis of some very implausible stipulations can pleasure
and the satisfaction of desire be identified. But Kant seems to use the two interchangeably, perhaps even to deliberately conflate them: I will suggest a bit later what
his point in doing so might be.
Whether as pleasure or satisfaction, happiness is, Kant emphasizes, inherently
subjective, and thus individual and unpredictable. It can only be empirically
determined—a crucial result because happiness is thus formally disqualified as a
source of laws for the will (5:25–6). Thus prudence, the virtue of practical reason
in its capacity as the servant of self-interest, operates without laws (5:25–6, 5:36,
cf. 4:418, 5:430). Further, the desire for happiness has its roots in our perpetually
unsatisfied natures as creatures of needs (5:25). To be human is to forever generate
new desires, so that there is never any point at which we can relax in satiation and
treat happiness as an acquis (5:430). And yet permanent and complete attainment is
part of its very concept: ‘all the elements which belong to the concept of happiness
are without exception empirical—that is, they must be borrowed from experience;
but . . . none the less there is required for the Idea of happiness an absolute whole, a
maximum of well-being in my present, and in every future, state’ (4:418).

description of happiness, and debate as to which conception is most central and/or defensible.

RACHEL BARNEY
So there is something paradoxical, phantasmagoric—and essentially unrealizable—
about happiness. Given that our inclinations are boundless, conflicting, everchanging, and only imperfectly knowable (4:418), the perpetual complete satisfaction
of all of them is not a genuine possibility: but that is what happiness is. This confirms
the strong suggestion of infantile fantasy in the definition of happiness cited earlier,
as the condition of a being for whom ‘everything goes according to wish and will’. It
is only in fantasies and fairy tales that everything goes according to my wishes; and
commands to elves and genies always backfire in the end. In real life, happiness must
outrun what my will can determine: it depends on ‘how things turn out’, on
unpredictable factors and forces beyond my control—hence the ‘hap’ in happiness,
the Glück in Glückseligkeit and probably the daimon in eudaimonia.
This phantasmagoric quality tells us something important, I think, about the status
of happiness so conceived (that is, happiness as total pleasure and/or satisfaction). It
is not only an ‘ideal of imagination’ (4:418), as Kant says; it is, so to speak, not a
concept for which he takes responsibility. It is our concept, not his, which he is trying
to capture—the fuzzy, incoherent fantasy-end we hazily envisage when we lunge after
the objects of our inclinations. This would be why Kant has no interest in trying to
define it more precisely as pleasure or desire-satisfaction, or some coherent amalgam
of the two.8 It is perhaps best seen as an impossible combination of two fantasies: as a
condition in which the perfect satisfaction of my will results in total and perpetual
pleasure. The important thing is that we recognize our own self-interested strivings
in some depiction along these lines.
But this cannot be the whole story. For the desire for happiness is both natural and
necessary to us, as Kant emphasizes (5:25). For us to renounce it is impossible. And
practical reason must be able to work within the limits of the possible—as we will see
again when Kant turns to argue that we must affirm the possibility of the highest
good. So there must be something else that happiness could be: the fantasy must have
a realizable counterpart, one which inherits its standing as a natural end but can be
endorsed and aimed at by practical reason. This is what Kant alludes to when he
qualifies a reference to ‘all inclinations taken together’ with: ‘which can be brought
into a fairly tolerable system, whereupon their satisfaction is called happiness’ (5:73).
Here and at other points Kant speaks of happiness as something systematized by
reason out of the raw materials of our inclinations—a maximal set of jointly
realizable inclinations, perhaps, or a life plan more deeply shaped by prudence,
self-knowledge, and experience. It is happiness so understood which is pursued by
self-love under the guidance of prudence (4:416 n., 6:46 n.). This happiness too is an
8
Alternatively, as Sergio Tenenbaum has suggested to me, we might take Kant to assume that it is
always a representation of some object as pleasant which makes it the object of my inclination, so that for
‘everything to go according to my wish’ is for me to be pleased: pleasure and desire-satisfaction coincide
except in cases of error. This would not settle the question, though, of which is constitutive of happiness, or
what to say about cases in which the two come apart. Cf. Reath 1989 for a subtle reading of the role of
pleasure in Kantian moral psychology.
THE INNER VOICE
163
‘Idea’, and might be unattainable in its perfect form, as is perfect virtue in this life, but
we can still rationally strive to maximize it.
When Kant speaks of happiness as a component of the highest good, it is this
happiness-as-rational-system which he has in mind. Kant at this point converges
with a more traditional, objectivist understanding of happiness as the real long-term
welfare—as Kant puts it, the ‘lasting advantage’ (4:416 n.)—of an agent. But there is
no retreat here from Kant’s understanding of happiness as consisting in pleasure or
subjective satisfactions: rather, he is making the further claim that a rationally
endorsable, enduring system of such satisfactions is constitutive of an individual’s
good.
Kant is not as explicit as we might like about the precise relation between
happiness as fantasy and happiness as system. But it clearly would be wrong to
think of these as theoretical competitors for the title ‘happiness’. Nor, on the other
hand, are they just different ‘senses’ of the word, harmlessly distinct once disambiguated. (Kant certainly shows no interest in any such disambiguation.) Rather,
these ways of thinking about happiness are complementary, differentiated by their
relation to practical reason. The systematic end is the imaginative ideal brought into
focus: it replaces the fantasy in guiding our actions insofar as our practical reason is
developed.
II Conditionality in the Highest Good
Once we have a grasp of happiness as system, we can be led to see that it is incomplete
as an end of practical reason, and can only be valued in conjunction with moral
virtue. Kant appeals to our moral responses here: ‘a rational and impartial spectator
can never feel approval in contemplating the uninterrupted prosperity of a being
graced by no touch of a pure and good will, and . . . consequently a good will seems to
constitute the indispensable condition of our very worthiness to be happy’ (4:393).
The pleasure and pain (the Wohl and Weh) of moral agents only has objective value
and disvalue in proportion to their moral condition:
When . . . someone who delights in annoying and vexing peace-loving folk receives at last a
right good beating, it is certainly an ill, but everyone approves of it and considers it as good in
itself even if nothing further results from it; nay, even he who gets the beating must acknowledge, in his reason, that justice has been done to him, because he sees the proportion between
welfare and well-doing, which reason inevitably holds before him, here put into practice. (5:61)
As this shows, ‘happiness, though something always pleasant to him who possesses it,
is not of itself absolutely good in every respect but always presupposes conduct in
accordance with the moral law as its condition’ (5:111). Conversely, virtue, though
good absolutely, is not ‘the entire and perfect good as the object of the faculty of
desire of rational finite beings. For this, happiness is also required’, and that from an
164
RACHEL BARNEY
impartial and not merely a subjective, self-interested point of view (5:110).9 These
arguments converge from both sides to show that ‘happiness, though it indeed
constitutes the second element of the highest good, does so only as the morally
conditioned but necessary consequence of the former’ (5:119). Thus constructed by
this asymmetrical conditional relation, the highest good emerges as the final end of
pure practical reason.
Kant’s arguments appeal both to the intuitions of an impartial observer and to the
principle that the highest good must be characterized by sufficiency, leaving out no
part of what we may rationally desire. But as several scholars have brought out, the
highest good as end can also be seen as a necessary construction from the moral
law.10 To be governed by the moral law is to adopt the standpoint of virtue; and only
to the extent that we adopt that standpoint are we rationally entitled to pursue our
own happiness as end. Thus the moral law gives back to us, in rationalized form, the
end which it had seemed to take away. And so virtue is necessary for happiness to be
genuinely good—i.e. for it to be the object of my rational will. As Stephen Engstrom
sums up: ‘Kant’s idea that the universalized claim is necessary and sufficient to
validate self-love’s claim that personal happiness is good amounts to the idea that
virtue is a necessary and sufficient condition of the goodness of happiness’ (1992,
762).
At this point we need to be careful not to be misled by a superficial resemblance to
certain ancient ideas. Anyone familiar with ancient versions of conditionality might
be tempted to take this point about ‘the goodness of happiness’ as amounting to
something like Aristotle’s claim that natural goods such as wealth or health are good
only for the good man (EE VIII.3). But there can be no real analogy here. For Kant is
talking about happiness itself: our natural self-interested end, not the raw materials
whose acquisition and use might tend to bring it about (the ‘natural goods’ or ‘goods
of fortune’ of the ancients), and which therefore might or might not be ‘good for us’.
In fact it is not clear that Kant has, or could have, the Platonic-Aristotelian category
of ‘good for x’ as opposed to good simpliciter: in any case he does not invoke it here,
either by saying that the villain’s happiness is good for him but not good simpliciter,
or by saying that it is not even good for him. Instead he insists only that it is not good
absolutely in all respects and without qualification (5:60, cf. 5:62). The villain’s
pleasures and satisfactions are, it seems, no less constitutive of his happiness than
the good person’s: they just cannot be rationally willed by anyone, even himself.
9
A fuller account (complete with a kind of ‘original position’) comes in the Religion (6:5–6). Kant’s
sufficiency arguments proceed by the same kind of thought experiment as we find in Plato’s Philebus
(20c–21a) and Aristotle’s Nicomachean Ethics (X.6–7). To assess a candidate for the highest good, imagine
a life which enjoys it to the fullest extent, but is stripped of any other conceivable good; and ask whether
that life would be complete and sufficient in its desirability. Engstrom goes so far as to say that ‘the
consummate good is the self-sufficient good, and thus Aristotle’s and Kant’s formal characterizations of the
highest good are fundamentally the same’ (1996, 122).

THE INNER VOICE
165
A third difference will emerge as crucial later on. This is that Kantian conditionality,
unlike the ancient species, is an ‘internal’ relation only insofar as it is normative. That
is, it follows from the nature of happiness and virtue that the former ought to track
the latter—or, in other words, that it is good only to the extent that it does so. But the
realization of conditionality in the world, in the form of happiness proportional to
the virtue of its subject, is not caused by any internal or direct causal relation between
the two—as it is in the ancient systems, in which virtue is psychologically constitutive
of happiness or at least a necessary condition for it. Rather, the relation is brought
about only externally, by a rational will determined to make it so.11 (I will have more
to say about this in section IV.)
Kant’s account of the highest good is complicated by two ambiguities. One is
between the highest good as a social or secular and as a divine achievement (cf. Reath
1988). The former can in turn be seen in either of two ways: we can either hope for
future human progress towards the highest good or, somewhat mysteriously, we can
view our actions now in relation to ‘a corpus mysticum of the rational beings’ in
society (A808/B836). Either way, it is a human achievement: rational beings ‘would
themselves be the authors both of their own enduring well-being and of that of
others’ (A809/B837). But Kant himself seems to treat this conception as incomplete
or preliminary, using it to prime us for the ‘theological’ one.12 What aids the
transition is that, even in presenting the secular conception, Kant stresses that the
actions of this community of rational agents are ‘just as if they had proceeded from a
supreme will’ (A810/B838). That is, it is only insofar as a community of rational wills
approaches the condition of a unified divine will that it begins to produce the highest
good (cf. 6:97–8).
Second, Kant oscillates between two somewhat different formulations of the
highest good. For Kant sometimes speaks of the highest good in terms of perfect
virtue and the perfect happiness appropriate to it, either in the individual or in ‘the
most perfect world’—the ‘maximal’ conception, as Beck calls it (1960, 268ff.)—and
sometimes as the conjunction of any degree of virtue (or the lack of it) with the
proportionate degree of happiness. There is no conflict between the two, insofar as
11
For the purposes of this chapter I for the most part bracket the question of whether we should think
of the highest good as being realized in this world, the afterlife, or both—a puzzle which is intertwined with
the distinction between the social or secular and the theological conception of the highest good, the unclear
division of labour between human and divine agency, and the distinction between the phenomenal and
noumenal realms. As with the secular/theological distinction itself, Kant is remarkably casual on this
question: e.g. ‘either in this or in another life’ (A812–13/B840–1). What is important is the negative point
that the proportionality essential to the highest good is not to be found in the empirical present: where we
do envisage it—coming into existence in a future society, or hidden in a noumenal corpus mysticum, or
postponed to the infinite afterlife—is apparently a matter of detail, irrelevant to the value of the attitude we
are required to take to it (namely, hope).
12
As Reath notes, in both the first and the second Critique Kant shifts from the secular to a theological
conception: he ‘begins by viewing the Highest Good as an end to be promoted in this world. But when he
imagines its realization, he conceives of it as a state of affairs in another world that would result from divine
agency’ (1988, 608).
166
RACHEL BARNEY
maximization is a special case—the ideal or optimal case—of the proportional
principle. The difference is presumably a matter of the emphasis appropriate to
different contexts. Maximization is salient when we consider our own defective
progress towards virtue: it grounds the postulation of immortality in an eternal
hereafter, in which we may advance towards perfectability without end (5:122–3).
Proportionality in general is salient to the question of whether the conditionality
relation which structures the highest good can be realized at all, and by what cause: it
grounds the postulation of a divine agent (5:124–5, A810–13/B838–41). Since the
latter formulation brings Kantian conditionality into sharper relief, it will be my
focus for the rest of this chapter.
Kant’s insistence on the necessary proportionality of the highest good is fraught
with philosophical difficulties, and a number of interpreters have been inclined to
marginalize it or read it in deflationary or non-literal terms.13 Some of the objections
to it are epistemic: how can we promote the highest good if this requires us to judge
the virtue of others, which depends on motivations to which even they have only
unreliable access (4:406–7)? Kant might respond that at most this makes the pursuit
of proportionality difficult rather than impossible. It is, after all, in the interests of
proportionality that one gives the vexatious person a right good beating, and Kant
exhibits no deep qualms about such everyday exercises in just deserts. Of course,
virtue is not a fixed quantity, and one might object that we should be trying to
increase the vexatious person’s moral worth rather than trying to reduce his happiness to fit our assessment of his current state.14 But there are epistemic and practical
difficulties here as well: and Kant is deeply sceptical of the idea that the virtue of
others could be part of my ethical task (6:386).
Still, it might seem ethically repellant to suppose that for us to reduce the happiness
of others could ever be a requirement of Kantian practical reason. Intuitively, one
imagines the agent deeply concerned with proportionality as unpleasantly moralistic
and self-righteous, and very likely self-deceived or self-serving. (As Nietzsche said,
‘Mistrust all in whom the impulse to punish is powerful’, Also Sprach Zarathustra
II.29.) And in Kantian terms it seems to violate the injunction that I should promote
the ends of others, as part of treating them as ends in themselves—even granted that
there must be limits to how far I should actively collaborate in misguided ends
13
See e.g. Reath 1988, 611–13, Beck 1960, 268ff., Engstrom 1992, 768–73, Friedman 2008.
Deterrence and moral education might even be added benefits of the beating. But Kant is clear that it
elicits our approval not for these reasons, but simply as an exercise in proportionality: ‘everyone approves
of it and considers it as good in itself even if nothing further results from it; nay, even he who gets the
beating must acknowledge, in his reason, that justice has been done to him, because he sees the proportion
between welfare and well-doing . . .’ (5:61, my emphases). As Sergio Tenenbaum points out to me, the case
confirms that, in order to satisfy the norm of conditionality, proportional outcomes require causal
connection as well as coincidence. It would hardly be equally satisfactory if the vexatious person suffered
from an equally painful toothache—or so it seems to me, at any rate, though intuitive reactions here seem
to vary.

(6:388).15 To limit anyone’s attainment of licit ends in accordance with desert is
surely, as Lewis White Beck memorably puts it, ‘the task of a moral governor of the
universe, not of a laborer in the vineyard’ (1960, 245). Moreover this could hardly be
intended as a new moral requirement; for Kant himself says that the highest good is
not the object of a further duty. As he puts it, in a slightly mysterious formulation,
‘harmonizing with this end does not increase the number of morality’s virtues
but rather provides these with a special point of reference for the unification of all
ends’ (6:5).
However, it does not follow that proportionality can be none of our ethical
business. No doubt, given the epistemic difficulties and the ethical pitfalls, it will
rarely fall to us to deliberately curtail the happiness of the bad. For us to do so,
however, is no violation of the moral law, or even an addition to it, given the
construction of the highest good from the moral law: for the happiness of an agent
is only in fact good, and thus a rational end, in proportion to his virtue. Kant is
emphatic that we must recognize this even in the first-personal case: ‘Reason does not
approve happiness (however inclination may desire it) except insofar as it is united
with worthiness to be happy, that is, with moral conduct’ (A813/B841). Our intuitive
recoil from the prospect of administering proportionality is natural and right, given
the universality of human frailty and imperfection: as Hamlet says, ‘Use every man
after his desert, and who should ’scape whipping?’ (II.ii). But it is equally repulsive to
suppose that, even in the most extreme cases, we have a duty to help the deeply
wicked live happily ever after—as we would were it not for the limitations imposed by
the norm of conditionality.
What these shifting, uneasy intuitions help to make clear is that the construction of
the highest good from the moral law, which involves a reconception of virtue as the
worthiness to be happy, is also the construction of something not previously visible in
the Kantian system: namely the moral norm of justice, fairness, or desert.16 As Wood
puts it, ‘Pursuit of the second component of the highest good is, in effect, beneficence
limited by justice’ (1992, 402). What Kant’s preference for describing the highest
good in terms of proportionality brings out is his intense if otherwise underarticulated commitment to this norm—to justice or fairness tout court we might
say, quite apart from any specialized juridical or political concept—a commitment
which he takes all of us to share. For Kant it is a central feature of the moral life that
15
As Ralf Bader has pointed out to me, here and in the next paragraph I gloss over a number of
problems about how proportionality, particularly as presented at 5:61, is to be reconciled with Kant’s duty
of beneficence and its derivation from the moral law. See the careful discussions of Engstrom 1992, 768–73
and Friedman 2008, 327–30.

My talk of justice as the Kantian norm achieved by proportionality has, admittedly, no real
counterpart in Kant’s own official formulations of the highest good. But I cannot think of any more
suitable name for what our ‘inner voice’ demands and divine proportionality achieves. And Kant does
speak of the villain as acknowledging the justice of his beating. Perhaps he avoids thematizing proportionality in these terms in order to reserve ‘justice’ for the very different concept elaborated in his political
works: I will have nothing to say about how these concepts might be related.

gross failures of proportionality are all around us, and that this is naturally felt to be
intolerable. In elaborating on the ‘moral proof ’ of God in the third Critique, he says:
This moral proof by no means [offers] a newly discovered basis for proving [the existence of
God], but at most a new elucidation of that basis . . . Once people began to reflect on right and
wrong . . . they inevitably had to arrive at this judgment: that in the end it must make a
difference whether a person has acted honestly or deceitfully, fairly or violently, even if to
the end of his life he has received no good fortune for his virtues and no punishment for his
crimes, at least none that we could see. It is as if they heard an inner voice that said: This is not
how it should be. (5:458)17
Or as Mark Johnston puts it (speaking of Kant, but in the context of motivating his
own inquiry into the prospects for an afterlife):
When faced with the contrast between the professional torturer who dies calmly in his sleep at
a ripe old age surrounded by his adoring family, and the nurse who, for her whole adult life,
cared for the dying only to herself die young and alone from a horribly painful and degrading
illness, people do tend to fall into despair over the importance of goodness. Unless, that is, they
have hope or faith. (Johnston 2010, 11)
Kant’s postulation of real proportionality, and a God who effects it, is the rationalized
expression of this inner refusal to accept our experience of the world, with its
monstrous injustices, as the totality of what there is. To say that the achievement
of the highest good must be possible is to identify with this inner voice, and
acknowledge it as the voice of reason. The next step is to see how the demands of
the inner voice are to be met.
III The Highest Good and Divine Agency
Kant takes the rational requirement to pursue the highest good to imply a possibility
requirement: in order to adopt the highest good as the object of our will, we must
hold its realization (and proportionality in particular) to be possible. As Kant puts it,
‘pure practical reason must necessarily think [the highest good] as possible because
reason commands us to contribute everything possible to its realization’ (5:119). This
possibility requirement in turn leads (quickly if somewhat mysteriously) to a further
requirement, in relation to which proportionality is again emphasized.18 Since the
world of experience reveals no coincidence between virtue and happiness, I must
17
A complication I here set aside (but which strikes me as important) is that in discussing the Spinozist,
Kant presents the empirical realm available to him as not only unjust but meaningless: not only do the
righteous suffer deprivation, disease, and death like anyone else, ‘they will stay subjected to these evils
always, until one vast tomb engulfs them one and all (honest or not, that makes no difference here) and
hurls them, who managed to believe they were the final purpose of creation, back into the abyss of the
purposeless chaos of matter from which they were taken’ (5:452).
18
As well as the requirement that we postulate the immortality of the soul, which is driven by the
‘maximization’ version of the highest good (5:122).
THE INNER VOICE

postulate a further realm and a cause which is able to realize it—namely God.19 This
pair of steps are summed up as follows:
The same law must also lead us to affirm the possibility of the second element of the highest
good, i.e., happiness proportional to that morality; it must do so just as disinterestedly as
heretofore, by a purely impartial reason. This it can do on the supposition of the existence of a
cause adequate to this effect, i.e., it must postulate the existence of God as necessarily belonging
to the possibility of the highest good (the object of our will which is necessarily connected with
the moral legislation of pure reason). (5:124)20
Note Kant’s emphasis on proportionality in this context, repeated at 5:125: ‘the
existence is postulated of a cause of the whole of nature, itself distinct from nature,
which contains the ground of the exact coincidence of happiness with morality’.
The great puzzle here, of course, is what exactly is supposed to generate this pair of
postulates. At times it seems that Kant is relying on what we might call the argument
from frailty: we cannot be steadfast in our commitment to the moral law without
some hope that the highest good will be realized. This argument amounts to an
empirical psychological prediction: we will lack the fortitude to steadfastly do the
right thing if we are convinced that the injustice and moral chaos we see around us is
all there is. Practical reason demands that we take the steps necessary to prevent
ourselves from lapsing from the moral law: hence it demands that we postulate, first,
the possibility of the highest good; and second, in order to secure that possibility, the
existence of God.
19
I here mean to largely bypass certain questions about the status of the postulation of God (see Kuehn
1985 for discussion, in terms of a helpful sorting into ‘traditionalist’ and ‘modernist’ or ‘existentialist’
interpretations, and his own ‘deductive’ alternative: cf. also Scutt 2010.) I take it that Kant’s argument is not
intended simply as rhetorical, aimed at persuading us that God exists. But neither does it straightforwardly
prove that God exists—a truth, if it is one, belonging to speculative and theoretical reason. What it aims to
prove is rather the more complex proposition that it is rational for us to postulate that God exists, which,
rather problematically, cannot be reduced to, and does not even entail, the proposition that he does. It is
this irreducibility which I take Kant to be granting when he emphasizes the first-personal and subjective
(not to be confused with merely personal and optional), and above all strictly practical character of the
postulate (e.g. 5:124–5). At times he even phrases this postulation as a kind of performance of commitment:
‘I will that there be a God . . . I stand by this and will not give up this belief ’ (5:143).
20
An oddity of the argument which has received relatively little discussion is that Kant here says only
that we must hold the highest good to be possible; but to do so evidently requires supposing that God is
actual. This asymmetry is puzzling: as Wood notes, ‘if God’s existence is both necessary and sufficient for
the actuality of the highest good, then belief in the highest good would seem equivalent to the belief that
God is possible’ (1992, 405). As Wood notes, Kant does occasionally retreat to this weaker position. But his
standard formulation is unambiguously stronger: ‘Therefore, it is morally necessary to assume the
existence of God’ (5:125). However, it is not hard to make an intuitive case for this stronger stance.
First, when we are considering practical possibilities (the possibility, for instance, that some action of mine
will be successful), we find it natural to describe outcome z as possible only if its preconditions x and y are
actual. (For instance: it is possible for me to fly, if I have [actually] wings and the bone structure of a bird.)
And God as divine cause is perhaps best understood as a precondition for my successful participation in
bringing about the highest good, as sketched above. Second, if God does not exist, the right kind of
connection between virtue and happiness can never obtain: the highest good turns out to be outright
impossible. For a careful reconstruction of Kant’s reasoning here, see Guyer 2000.

RACHEL BARNEY
Several of Kant’s expressions of the possibility requirement are very much in this
spirit (e.g. 6:5). This reading also dovetails with Kant’s suggestions that the worry to
which the possibility requirement responds is first-personal: what I must believe
possible is that my commitment to the moral law will be matched by my happiness.21
Still, the argument from frailty cannot be the whole story. To claim that we cannot be
steadfast in our moral commitments without hope would be to elevate an empirical
psychological generalization to the status of a necessary causal truth, a kind of move
which Kant regularly denounces as improper in moral philosophy (e.g. 5:26). The
argument from frailty cannot make the possibility requirement more than nearly
necessary, as a matter of how human motivation typically works; and the chasm
between the nearly necessary and the genuinely so is absolute. There remains the
possibility of what we might call Spinozist heroism (or, equally well, ‘existentialist
heroism’ or ‘film noir heroism’): a commitment to the moral law which remains
steadfast (i.e. reliably overrides any conflicting self-interested motivations) despite a
complete absence of any hope for the highest good. And in fact Kant’s discussion of
the Spinozist seems to consider the position of just such an agent:
Therefore, let us consider the case of a righteous man (Spinoza, for example) who actively
reveres the moral law [but] who remains firmly persuaded that there is no God and . . . that
there is also no future life: How will he judge his own inner destination to a purpose, [imposed]
by the moral law? He does not require that complying with that law should bring him an
advantage, either in this world or in another; rather, he is unselfish and wants only to bring
about the good to which that sacred law directs all his forces. Yet his effort [encounters] limits:
For while he can expect that nature will now and then cooperate with the purpose of his that he
feels so obligated and impelled to achieve, he can never expect nature to harmonise with it in a
way governed by laws and permanent rules (such as his inner maxims are and must be).
(5:452)
Kant presents the Spinozist as confronted with a dilemma: either lapse into disrespect
for the moral law, or accept the possibility of divine agency. Since the former is ex
hypothesi unacceptable to him, we are to see him as perpetually teetering on the brink
of acceptance of the postulates:
And so this well-meaning person would indeed have to give up as impossible the purpose that
the moral laws obligated him to have before his eyes, and that in compliance with them he did
have before his eyes. Alternatively, suppose that, regarding this [purpose] too, he wants to
continue to adhere to the call of his inner moral vocation, and that he does not want his respect
for the moral law . . . to be weakened, as would result from the nullity of the one ideal final purpose
that is adequate to this respect’s high demand (such weakening of his respect would inevitably
impair his moral attitude): In that case he must—from a practical point of view, i.e., so that he
21
E.g. ‘Not being nature’s cause, his will cannot by its own strength bring nature, as it touches on
his happiness, into complete harmony with his practical principles’ (5:124, my emphasis). Cf. 5:129–30,
A813/B841.
THE INNER VOICE
171
can at least form a concept of the possibility of [achieving] the final purpose that is morally
prescribed to him—assume the existence of a moral author of the world, i.e., the existence of a
God; and he can indeed make this assumption, since it is at least not intrinsically contradictory.
(5:452–3)
If the problem with the Spinozist is not simply that he is psychologically vulnerable to
lapsing from the moral law, what exactly is wrong with him? Since Kant presents the
possibility requirement as a demand made by practical reason, the question is in what
way the Spinozist is being irrational. Zev Friedman has argued that the postulates are
rationally required for the legitimate authority or objectivity of the moral law, which
Spinoza accepts. For ‘if the fate of the morally worthy and the morally unworthy does
not reflect their relative worthiness . . . the moral law cannot be understood to be
objective. Rather, the law must be discarded as an empty projection of the agent’s
mind’ (2008, 326)—a subjective delusion, answering to nothing in the way the world
is, like the inner narrative of someone who believes himself to be Napoleon. ‘Unless
the natural order is understood to be under the hegemony of the moral order the
moral law cannot claim objective status’ (2008, 342).
Kant does seem to flirt with this argument from the legitimacy of the moral law, as
when he says that the impossibility of the highest good would render the moral law
‘fantastic, directed to empty imaginary ends, and consequently inherently false’
(5:114).22 For the most part, though, Kant is hostile to any suggestion that the
moral law could depend for its authority on anything else at all—including the
postulation of God (5:125–6).
I would suggest that both the argument from frailty and the argument from the
legitimacy of the moral law are, for Kant, sidelines. Neither is his principal
argument—or even the right kind of argument—for the possibility requirement.23
Instead, there is no argument: Kant simply asserts the possibility requirement as
obvious. Why might it seem so? Probably because it is natural to suppose that one
22
Likewise a startling passage from the Lectures on Ethics: ‘Morality implies a natural promise:
otherwise it could not impose any obligation upon us. We owe obedience only to those who can protect
us. Morality alone cannot protect us’ (Infield 1981, 82; cf. A811–14/B839–42).
23
What are they then? Responses to objections, I would suggest. The argument from frailty turns to
Kant’s own purposes the protest that the moral law demands an unrealistic degree of unselfishness from us.
The argument from the legitimacy of the moral law does the same for the objection that it is unfair to
demand that we subject ourselves to unenforced laws. Here as elsewhere (see section V below), Kant’s
reasoning needs to be read in its dialectical context. Addressed to someone not already committed to the
moral law, the possibility requirement could only serve as a corrupting incentive. Addressed to a confirmed
believer in Christian theodicy, it is unnecessary. Kant’s reasoning is addressed to an interlocutor in roughly
the unstable position of the Spinozist, who, while denying the rationality of faith, might well also feel
threatened with despair or tempted by a Job-like protest against the injustices around us, and so might be
responsive to these incentives to the will. (For the general point that his concepts and theses must be
grasped in a certain sequence, cf. 5:64; for the idea that one incentive might be legitimately deployed only to
balance another, cf. 5:88; for Kant’s reading of Job, cf. ‘On the Failure of All Philosophical Theodicies’, in
Despland 1973.)

RACHEL BARNEY
cannot genuinely intend the impossible (de dicto).24 If I believe that X is impossible,
then X cannot quite be the object of my action, which we need to redescribe in terms
of some other end in the vicinity. I think that this is very likely a defensible principle,
and a useful constraint on our ascriptions of intention.25 It seems reasonable, for
instance, that someone who votes for a fringe party without having any hope of their
victory should be described not as intending to elect them and enact their policies (or
to join others in doing so), but rather as sending a certain message, registering a
protest, and so on. And even someone fanatical about making healthy choices should
not be described as doing so with the intention of living forever—unless we want to
claim that she is mad—but only as hoping to remain healthy for as long as possible.
So if we may take it that Kantian willing is or incorporates intending (I will return
later to this assumption), for me to will the highest good without believing it to be
realizable is not a genuine possibility. As Kant puts it: ‘But the subjective effect of this
law, i.e., the intention which is suitable to this law and which is necessary because of
it, the intention to promote the practically possible highest good, at least presupposes
that the latter is possible. Otherwise it would be practically impossible to strive for the
object of a concept which, at bottom, would be empty and without an object’ (5:143).
Thus belief in the possibility of the highest good turns out to be a demand of
practical reason because it is a necessary prerequisite for states of the will which are
themselves demanded by practical reason—necessary as a matter of the logic of
intention, not just nearly necessary given common human motivational weaknesses.
We can now see, I think, the nature of the Spinozist’s failing. It is not that he is (as per
the argument from frailty) doomed to discover at some point that he is too weak to
persist in his commitment to the moral law. Nor is it (just) that he is being irrational,
refusing to respect the entailment relations among his commitments. Rather, his will
is at an impasse: he cannot really will the highest good at all, since he considers it
unavailable; yet he recognizes that practical reason requires him to do so. He tries to
fall back on his commitment to the moral law, suppressing all selfish inclinations; but
it is the moral law itself which in turn generates the requirement to pursue the highest
good, which he cannot do. Until he assents to the postulates, his reasoning can only
run round in a doomed circle, like someone whose most careful calculations keep
giving an obviously wrong result.
24
Contemporary philosophers debate whether intending to ç requires believing that one will succeed
in ç-ing: that I must at least consider it a ‘live possibility’ that I will succeed seems to be uncontroversial.
(See Holton 2008, with references.)
25
Cf. Wood on the argument as ad absurdum practicum (1970, 27–30) (though Kant’s explanation of it
in those terms is, to me, per obscurior). Wood also raises the question whether we should read Kant as
holding that it is impossible to intend what is believed to be impossible, or only that it is irrational (1970,
21–3, cf. 1992, 401); I here opt for the stronger reading. One might object that this is too strong, since the
position of the Spinozist seems to be presented as possible, and Kant consistently emphasizes that the
postulates are rational requirements. However, the distinction is not so clear-cut as we might assume: a
stance which is irrational may be impossible to hold transparently, and it is hard to say how transparent the
Spinozist’s predicament is to him.
THE INNER VOICE
173
On this reading, however, a major difficulty looms: if the possibility requirement is
grounded on this principle about the availability of intentions, it does not obviously
support the further postulation of God—indeed the two may not even be compatible.
For if I must think that the end of my action is possible, this is surely because, more
precisely, I must think that the success of my action is possible. Suppose that the
question is whether I can intend ‘flying to the top of the Empire State Building’. If
Kant’s claim is that I can do so only if I believe that ‘flying to the top of the Empire
State Building’ is possible, surely this is elliptical for my flying, the very flying
I purport to intend. Whether birds can do it is irrelevant to what I can intend. In
the same way, that God can bring about a necessary proportional relation between
virtue and happiness does nothing to show that I can. Worse, if his actions are
sufficient for that end, then my own actions and intentions seem to be otiose at best.
Whether and how God’s agency leaves any room for my own to be efficacious at all is
a sticky question, to which I will return in the next section: at a minimum, we might
object that it renders my own agency unnecessary, while doing nothing to secure its
possibility. The moral agent turns out to be like a child who is encouraged to think
he is steering the shopping cart, making the soup, etc. while really the parent does
everything.
This problem of the division of labour between the human moral agent and God is
bound up with a more general interpretative dilemma. Our own actions, after all, can
only aim at bringing about the highest good in a local and imperfect way. So what is
it, exactly, that we must believe possible: is it merely that at least some of our actions
aimed at that end will meet with success? Or must we believe in the possibility of the
perfect, total realization of the highest good, which only God or some perfected
community of rational human wills can provide?26 Only the former seems to follow
from the principle that I cannot intend what I consider impossible; but only the latter
seems to require the postulation of God. The problem can be put as an objection
from the Spinozist. Why is it not sufficient for me to believe that the highest good
(and more specifically, proportionality) can be realized on some occasions by my
actions—that happiness and virtue can be brought to coincide occasionally, that good
guys don’t always finish last? Even the film noir hero hopes for this much; and it is all
he needs in order to act.
To answer this, Kant needs a principle to the effect that we can believe that the
highest good is possible even locally and imperfectly only if we believe that it can be
perfectly realized. Now I think that Kant does in fact accept such a principle, and has
some defensible (up to a point) reasons for doing so. To bring these out, we need to
look more closely at the relation of divine and human agency, and at what Kant
means by presenting the highest good as the object of our hope.
26
This dilemma is not resolvable into the distinction between the ‘maximal’ and ‘proportional’
formulations of the highest good: the problem is specifically whether I can make proportionality my end
while considering it possible only locally.

IV Hope and Justice
The postulation of God does much more than assure us that, in the long run, virtue
and happiness will coincide.27 It attributes that coincidence to an infallibly reliable
cause,28 one rationally guided by the norm of conditionality. Thus the relation
between virtue and happiness turns out to be a necessary and a causal one—not
one of ‘internal’ or immediate cause and effect, however, but one mediated by the
divine rational will. This necessary causal relation, Kant emphasizes, is itself part of
what we will when we make the highest good our object (5:111, 5:113–15). I will my
happiness not only proportionally, insofar as I am worthy, but as an effect of that
worth—and not, say, the other way around.
This kind of causally structured object of the will is familiar enough, as are cases
where the causality must be mediated by the will of another. Think of a student,
Annie, who works hard on a paper. Annie wants two things: to write a good paper
and to receive a good grade. If she writes a good paper and gets a C, she will be
pleased in one respect and disappointed in another. If she writes a bad paper and gets
an A, she will again be partly pleased but also disappointed—disappointed in herself
and perhaps in her professor as well. Now imagine that she writes a good paper and
receives an A; but she then learns that the paper was never read by Professor Careless,
who assigns grades by a roll of the dice. In this case, both of Annie’s desires, as
initially specified, are satisfied. Yet surely this outcome will be at least as insufficient
and frustrating as the other two. So something was missing from the initial characterization: Annie did not want two things, to write a good paper and to get a good
grade, but a single complex thing: to get a good grade as a result of having written a
good paper. The conditionality specified by the causal link is itself a part of the object
of desire.
What we want in cases like this is to be rewarded for acting well: what we want, in
short, is justice. And justice is not done if mere coincidence happens to bring about a
proportional result. Even in the movies, we do not want the villain to suddenly die
from an allergic reaction or a subway accident unless we can somehow interpret it as
telling, and a form of cosmic justice: his death must somehow be seen to result from
his own wicked actions and character. Moreover, Kant may reasonably insist that the
causal link demanded here is a necessary and universal one. Like the assassin who
shouts, ‘Sic semper tyrannis!’, what I will in willing the highest good outruns
anything I can myself perform, for I will my actions as applications of a rule.29
27
Cf. Engstrom: ‘the highest good is distinct not only from any condition in which happiness is not
proportional to virtue, but also from any condition in which the proportionality is fortuitous’ (1992, 750).
Cf. Reath 1988, 598.
28
Despite Kant’s avowed circumspection about entering into traditional speculative theology, it turns
out that many of God’s standard predicates can be deduced from the role assigned to him by practical
reason (5:140).
29
This is arguably a feature of all rational action according to Kant, since we cannot help but act on
maxims which are general in form. A fuller discussion of the issues here would have to say more about the
THE INNER VOICE
175
This requirement that the link between virtue and happiness be a matter of
necessary and universal causality is already enough to require the postulation of a
superhuman agency; and it also plausibly belongs to the content of the highest good
that this causal link be rational. We find it natural to think of justice as something
done or administered, rather than as a merely natural event, something that happens;
and Kant is in a good position to explain why that is. For in willing proportionality,
we will that virtue be rewarded with happiness qua moral worth or desert. And worth
and desert are properties which only reason can pick out and respond to—to expect
them to operate as natural forces is to misunderstand what they are. (As Iris
Murdoch puts it: ‘There is no triumph of good, and if there were it would not be a
triumph of good.’)30 This is for Kant one of the most basic respects in which the
ancient philosophers went wrong: if they were right that virtue was the natural,
‘internal’ cause of happiness, it could not be strictly as virtue (that is, commitment to
the moral law) but only as something else (psychological health, perhaps); and the
highest good would actually be precluded by that causal relation. Not only would
corrupting incentives to virtue be pervasive and inescapable, there would be no room
for any rational will to respond to virtue as such, and reward it as it deserves. From
the Kantian perspective, the internal conditionality insisted on in the ancient ethical
systems can only look like magic, an attempt to procure through our own powers
what is properly the gift of another. It is a form of conditionality which leaves no
room for justice to be done.31
All this entails that the highest good is impossible without God—not only in its
perfect realization, but even locally. (Thus the distinction between the ‘local’ and
‘perfect’ versions of his argument drawn above, which seemed to show his argument
to be equivocal, is in the end, Kant may argue, not significant.) For a merely local
occurrence of proportionality can only count as an instantiation of the highest good
to the extent that it can be seen as part of a necessary, universal, rationally willed
nature of Kantian willing, its relation to intending, and whether it can entail that local action for the highest
good involves intending its perfect realization. I here offer what seems to me a less proprietary ‘sufficiency’
argument: local instances of the highest good would be missing something valuable, and would thus fail to
count as instances of the highest good, if they were not the necessary effect of a rationally governed system.
30
Strictly speaking, as Murdoch’s character Bradley Pearson puts it, in The Black Prince (108).
This is perhaps an overstatement. In some versions of ancient conditionality, notably Aristotle’s,
room is left for divine luck (EE VII.2), or for ‘goods of fortune’ (EN I.10–12) which affect our degree of
happiness directly, not just by helping us to exercise virtue. But the goods of fortune are not generally
presented as literally the result of divine intervention, and the gods typically befriend the virtuous anyway.
Unambiguous references to divine interventions in human happiness in the ancient philosophers are
fleeting, and generally look like attempts at harmonization with pre-philosophical endoxa (e.g. EN
1179a22–32). There is a deep commitment to divine providence in the Socratic tradition (Plato, Apology
31a–b, 41d, Xenophon, Memorabilia I.4), which flowers fully in the Timaeus, Laws X, and Stoic theology.
But for the most part this attributes to God the establishment of a natural cosmic order in which (a) all is
for the best, and (b) goodness and wickedness naturally bring about—or indeed are—their own reward and
punishment in the long run (e.g. Theaetetus 176e–177a, Timaeus 42a–d, Laws 903b–905d). So divine
intervention at the individual level must either be understood allegorically or be taken to operate through
human character.

causal system. Only a supreme rational will can establish that; and such a will is in
turn sufficient for the perfect realization of the highest good.
We can now get a better sense of how human and divine agency must be related in
the highest good—namely, by a kind of collaborative agency. Only a tiny fragment of
the highest good can be directly produced by my will; what I will in willing it as the
highest good is that my actions form part of a greater, indeed a perfect whole. This
kind of collaborative and other-referring willing seems to be what Kant means by
hope. Its centrality is brought out by the status of hope as one of just three
fundamental attitudes of reason, with the highest good as its distinctive object.32
The highest good as a whole must be the object of both my will and my hope because
it can only be realized by a collaboration between my own will and a rational will
external to my own. (This is the truth behind the folk understanding that happiness
depends on the hap—on how things turn out beyond our own control.) It is
important that this attitude, demanded by the possibility requirement, is not a state
of knowledge; this would exclude hope, and its certainty would corrupt moral agency
with incentives. Indeed I would go further, and suggest that Kantian hope also should
not be understood as a belief, or as any epistemic state or propositional attitude at all.
(It is clearly not reducible to a belief that something is likely to happen—with what
degree of probability, exactly?—together with a pro-attitude towards its happening.
Such pro-attitudes might have an infinite number of miscellaneous objects, whereas
Kantian hope has a single defining one.)33 Belief in the normal sense is not subject
to our will, and cannot be morally required. Hope in the relevant sense is not a
propositional attitude or cognitive state but a practical stance, a condition of the will:
it is something we allow or deny ourselves, and Kant’s claim is that practical reason
requires us to allow it.34
This practical stance is in a sense a negative one: hope is a refusal to despair, or to
view one’s own commitments as doomed or absurd. But we can also describe Kantian
hope positively, as the state of the will in which we choose to view our actions as part
of collaboration with a will greater than our own. Hope is what a player in a band, a
string quartet, or a soccer team depends upon in acting. It is a commitment to a
particular form of seeing as—namely, to seeing my commitments and actions as
contributions to a common work commanded by God. Hence Kant’s frequent use in
this context of the language of seeing as, viewing, representing, recognizing, and so
32
A805/B833.
If hope is a matter of belief, it seems that my belief must be an absolutely certain one, since the
postulates are necessary conditions of the indisputable moral law. But Kant does not speak of it in those
terms, and it is hard to imagine how certainty about divine proportionality could avoid corrupting our will
with incentives.
34
I intend this paragraph as a somewhat tentative gesture towards a reading of Kantian hope. A full
discussion would have to consider the relation of hope to religious faith [Glaube], which does seem to be an
epistemic or doxastic state. If hope is in the end identical or reducible to Glaube, the Spinozist objection
above seems to me inescapable.

forth.35 This is how the possibility requirement and the postulation of God can be
genuinely new ethical requirements without adding to the content of my duty: they
do not demand further actions, but require me to view all my actions in a certain
light, as part of a collaboration with a rational will other and greater than my own.
What makes the postulation of God required, then, is that without reference to that
greater will, I cannot not perform the actions required of me under the descriptions
which the moral law commands that I will them. For the moral law commands that
I will the highest good as such, and to do that is to will my actions as contributions to
a system of just rational causality. In the absence of God, the moral agent would not
be like the man who thinks he is Napoleon, but like a sworn tax collector or border
guard in a state that has fallen into anarchy. The problem is not that he will in fact fail
in collecting taxes, but that he cannot even will his action under the description
‘collecting taxes on behalf of the government’, once he knows that there is no longer
any government. (So long as the bad news does not reach him, there is no ethical
problem, any more than there was for the Japanese army stragglers who never
learned of the end of the war: hence the adequacy of a strictly subjective postulate.)
This ultimately collaborative conception of moral agency helps to explain why
Kant feels entitled to offer both the secular and theological conceptions of the highest
good, as if they were interchangeable. What is distinctive about hope is that part of
what I will is deferred to the will of some independent Other; exactly what Other is
less significant, and perhaps makes no difference to the moral quality of the attitude
itself. Whether I place my hope in the future of mankind, or the corpus mysticum of
the righteous, or God, is comparatively speaking a question of detail.36
In short: the commitment to the highest good required by practical reason is best
understood as a commitment to seeing our own actions as collaborative contributions to a rational system of justice, a system in which the demands of the ‘inner
voice’ are satisfied at last. Now although I cannot argue the case here, it seems to me
that Kant is right to treat the inner voice, and its demand for proportionality, as a
central fact of moral experience, one to be respected by any account of the highest
good. It also seems to me defensible for him to hold that to will justice, as such, is to
will a universal system of necessary causality mediated by rational wills, and that
I must see my own contributions to that system as those of a merely junior partner.
The challenge which remains, though, is for Kant to show that hope in this practical
‘seeing as’ sense is sufficient to require postulation of the existence of God—
inescapably an epistemic or (more precisely) doxastic commitment as well as a
practical one. At this point we can once again imagine an objection from the
35
E.g. ‘the sensible world, viewed, however, as . . . a corpus mysticum of the rational beings in it’ (A808/
B836); ‘To view ourselves, therefore, as in the world of grace . . . is . . . a necessary idea of reason’ (A812/
B840); ‘we are necessarily constrained by reason to represent ourselves as belonging to such a world’
(A811/B839); ‘Religion is the recognition of all duties as divine commands’ (5:129).
36
Hence, given the validity of the secular conception of the highest good, Kantian ethics leads to politics
as directly as to religion: cf. Engstrom 1996, 132–3, who rightly notes here a parallel with Aristotle.

indefatigable Spinozist: why can I not undertake to think and will collaboratively,
independent of any belief that collaborators exist? As a musician, I can play the
second violin part of a symphony, as such, alone in the studio; as a private detective,
I can follow the police code of conduct even if I have been struck from the force; as
Don Quixote, I can obey the norms of chivalry in the wrong time and place; and as a
Spinozist, I can follow the commands of a religion in whose God I do not believe. As
Puddleglum the Marshwiggle says, at the darkest moment of The Silver Chair: ‘I’m on
Aslan’s side even if there isn’t any Aslan to lead it. I’m going to live as like a Narnian
as I can even if there isn’t any Narnia.’37 This kind of als ob commitment seems to be
a live psychological possibility, perhaps even a heroic one: if so, it shows that a
Spinozist Marshwiggle could adopt the collaborative stance without adopting any
epistemic postulates at all. Friedman reads Kant as, in effect, claiming that this could
only be the stance of a madman. But this is, I think, to ignore the distinction between
local and universal, and perhaps between intending and Kantian willing: even if I will
my action collaboratively and universally als ob, I can at the same time intend and act
locally in the world as it is. The assassin need not, in fact, think that there is any
chance that all tyrants will be assassinated, when he utters his cry and draws his
sword. He need only hope that his own particular action has some chance of success,
and offer it in a spirit of contribution to a common project with whatever likeminded spirits may be out there—whether there are any or not.38
V Conclusions
In the trajectory of argument I have sketched, Kant is, to a perhaps greater degree
than is usually appreciated, writing not just a logically structured exposition of a
theory, but also a narrative, with a moral-educational and psychagogic dimension. In
this he is following, consciously or not, some powerful ancient models. Like Plato in
the ‘ascent’ passages of the Symposium, Phaedrus, and Republic, or Cicero when he
delineates the stages of Stoic moral progress in De Finibus III, Kant is depicting
the stages through which the progressing moral agent must pass, so that we rehearse
37
Lewis 1965, 156–7. Puddleglum has at this point been half-persuaded by the Witch’s magic that there
is no world above the subterranean cave in which he and the children have been trapped. He begins his
peroration by admitting as much: ‘Suppose we have only dreamed, or made up, all those things—trees and
grass and sun and moon and stars and Aslan himself. Suppose we have. Then all I can say is that, in that
case, the made-up things seem a good deal more important than the real ones. Suppose this black pit of a
kingdom of yours is the only world. Well, it strikes me as a pretty poor one . . .’ (156). This is very much the
situation of the Spinozist forced to recognize the empirical world as a meaningless chaos (cf. n. 17 above),
or Friedman’s moral agent whose actions and self-conception find no support in the empirical world. Lewis
seems to propose that one can occupy that position transparently and rationally, and that it may even be
heroic to do so.
38
To spell out this objection a bit more: if Kantian hope is the non-doxastic ‘seeing as’ which I have so
far sketched, it does not require the postulation of God, but only a commitment to will als ob. If on the
other hand Kant means to insist that I must postulate the existence of God in order to act even with some
local instantiation of the highest good as my end, more argument is needed.
THE INNER VOICE

them imaginatively in following his argument: seeking happiness as an ‘imaginative
ideal’, to be brought into focus as a rational end; grasping and committing to the
moral law; coming to see both happiness and virtue as parts of the highest good,
related by the norm of conditionality; affirming that this highest good is possible;
and, finally, coming to hope for its achievement by collaboration with divine agency.
Each step involves a rethinking and repositioning of concepts and principles previously grasped incompletely or in isolation. Above all, this ascent amounts to an
ordered sequence of instructions on exactly how—in what spirit—we are to think
about happiness. For each step in moral progress involves a reconception of what
happiness is and how it is to be attained: from infantile fantasy to rational system,
from the object of a selfish maxim to a universalized one, from our natural end to
only a conditional part of the highest good, from the object of my rational will to the
object of my hope. This final step is in a way the most radical rethinking of all: for at
this point I come to think of my happiness as something I am to make myself worthy
of, so that it may be conferred by divine justice, rather than as something to be
directly procured by my own efforts.
Though I have cited some ancient precursors, this particular narrative of moral
ascent is not closely analogous to anything in ancient philosophical thought. And yet
Kant’s version of the highest good is intended as a rediscovery of some very old ways
of thinking about happiness and virtue. He says so himself, when in the passage
quoted earlier he cites the ‘inner voice’ which says, This is not how it should be, and
attributes it to the very dawn of moral judgement and reflection.39 Kant is right about
that: the inner voice can be heard, for instance, in Hesiod’s didactic poem Works and
Days, and the argument there is worth juxtaposing with his own. For the most part,
Hesiod simply affirms that Zeus rewards the righteous and punishes the unjust—all
around us, in the empirical world, though with a rough justice. Cities wickedly
governed suffer famine, plague, sterility, and war; wrongdoing always rebounds
against the wrongdoer in the end, thanks to the justice of Zeus. But then we get an
abrupt change of tack, quickly covered with a reassurance:
The eye of Zeus sees all, and understands all,
And when he wishes, marks and does not miss
What sort of justice a city holds within.
But as things are I would not myself be just, nor have my son
Be just among men: for it is bad
To be a just man where felons rule;
But I trust wise Zeus to save me from this pass.40
39
Given this passage, it is odd that Reath claims that ‘the secular version is predominant in the third
Critique and later works’ (1988, 601).
40
Lines 267–73, Wender trans., with revisions: in the last line, the construction is more literally ‘I do not
expect that’ Zeus will allow this. ‘Expect’ (elpizô) can also mean ‘hope’, and is related to the noun ‘hope’
(elpis).

Abruptly juxtaposed with Hesiod’s lengthy, repetitive promises of divine justice, this
brief glimpse of the alternative has the air of the mask slipping, and a private doubt
suddenly exposed. But this glimpse is itself a didactic strategy, and a clarification of
what precedes it. For here we see that justice is, in Hesiod’s world as in Kant’s,
deferred to the future tense. Of course there are important differences: Hesiod never
considers deferring justice all the way to an afterlife, or to an intelligible order distinct
from the sensible one. (The closest he comes is to defer retribution to a man’s
descendants.) Kant begins precisely where Hesiod refuses to go, with an acceptance
that we cannot perceive any justice or proportionality in the empirical order. But
there is nonetheless a formal and ethical similarity. In the end, Hesiod—like Kant—
demands of us not an empirically grounded belief in divine justice but a first-personal
commitment to hope, the only alternative to which would be a despairing refusal of
moral demands as rationally unacceptable. Thus for Hesiod as for Kant, hope (which
coincides with trust in divine justice) becomes a moral requirement.41
This kinship can help us to locate the Kantian conception of the highest good in
relation to its philosophical predecessors and alternatives. In accordance with Adeimantus’ demand, the conditionality affirmed by the ancient philosophers is a natural
and internal relation: virtue constitutes happiness, or causes it, or is at least a
psychological precondition for it, independent of outside circumstance. And Adeimantus’ demand is provoked by a disgusted rejection of what poets like Hesiod have
had to say about virtue and happiness (Republic 362d–367e). His question to Socrates
is, among other things, a request for a story about proportionality which does not
depend on divine intervention or any other external ‘rewards’. For one thing the
poets are, as he complains, inconsistent; sometimes they suggest that the gods favour
the wealthy, who can buy them off with rituals and display, and that cult initiates
have special advantages in the afterlife (364b–366a). Starting with Socrates, the
ancient philosophical systems respond by taking the gods out of the loop—and
with them the daimon and the ‘hap’. By making the relation of happiness to virtue
a matter of natural causality or even identity, the philosophers bring happiness fully
under the virtuous agent’s control.42
Kant’s embrace of conditionality is a profound rejection of this way of conceiving
it, and a reaffirmation of the more ancient Hesiodic conception.43 That is why hope is
a central value for both Hesiod and Kant, while it is only a peripheral value in any
41
Hope is also significant for Hesiod as the last resident of Pandora’s jar, a standing compensation for
the evils of human life (Theogony 96, cf. West 1978 for discussion).
42
Cf. Nussbaum 2001, though Nussbaum’s contrast between Plato and Aristotle seems overstated in
this context (that is, in comparison to what separates both of them from the poets and from Kant alike).
43
As Kant himself sees: ‘it now becomes clear why the Greek schools could never succeed in solving
their problem of the practical possibility of the highest good. It was because they made the rule of the use of
which the human will makes of its freedom the sole and self-sufficient ground of its possibility, thinking
that they had no need of the existence of God for this purpose’ (5:126, my emphasis). This confirms what we
can also infer from the ‘inner voice’ passage, namely that Kant’s postulation of divine agency, and of hope
as an ethical requirement, are not considered by him either as needed by or conceivable to Christians alone.
THE INNER VOICE

ancient system of philosophical ethics. And this sheds a retroactive light on Kant’s
rejection of the very idea of ancient eudaimonia: his assumption that of course
happiness is just a matter of obtaining pleasures or satisfactions is from the start a
rejection of the philosophers’ strategies of internalization. Kant starts from a modern,
pessimistic acceptance of the unmoralized nature of human inclination and satisfaction, and of the moral indifference of the world of experience; but his response is to
recover an ethical stance much more ancient than the ancient philosophers.
Whether this Kantian response represents philosophical progress, theological
regress, or just another turn of the great dialectical wheel is too hard a question for
me. Viewed from the outside, what is striking about this debate is that it is one in
which both sides can criticize the other as naı̈ve. From the Kantian standpoint,
Adeimantus’ demand is immature and doomed, an invitation to self-deception:
only by fudging the empirical data and adopting an artificially internalized conception of ‘happiness’ can a Plato or Aristotle insist that my virtue will naturally bring its
own rewards. But from the Aristotelian standpoint, it is the Kantian who is naı̈vely
optimistic, even primitive in his hope for a divine justice of which the empirical world
gives no evidence. It is possible, of course, that both accusations are correct.44
