ABSTRACT. Evidentialism is usually thought of as an inherently conservative epistemological
proposal; indeed, as a kind of antidote to epistemological radicalism. In an irenic spirit, however,
I want to argue that the core evidentialist theses are in fact compatible with some quite
heterodox positions in epistemology. I focus on two in particular that are close to my heart:
Wittgensteinian hinge epistemology and epistemological disjunctivism. My goal is not to
defend these positions, much less defend the combination of these positions with
evidentialism. It is rather to demonstrate, on the occasion of its anniversary, that what makes
evidentialism epistemologically conversative is not the core theses associated with this view,
but rather the ancillary commitments of its main proponents. This is a result that, I contend,
evidentialists should welcome.

1. INTRODUCTORY REMARKS
I want to consider the general idea of evidentialism. Evidentialism is often considered a quite
conservative option in epistemology, certainly when compared to its cooler relatives, like virtue
epistemology (or, dare I say, anti-risk virtue epistemology).1 My goal is not to defend evidentialism,
as it’s not a position I endorse, but rather to show that it is at least compatible with some quite
radical views in epistemology.2 I want to focus on two such proposals that I have been associated
with in my own work: the hinge epistemology advanced in Wittgenstein’s final notebooks (published
as On Certainty),3 and the epistemological disjunctivism that is rooted in the work of John McDowell
(e.g., 1995) and which I’ve offered a systematic presentation of in the language of contemporary
epistemology.4 That evidentialism is compatible with such views is not to say, of course, that the
defenders of evidentialism may be persuaded to reconceive of their proposal along these radical
lines. In fact, I suspect that they would be very resistant to any form of epistemological radicalism.
But what this does show, however, is that the conservative reputation of evidentialism is not due to
the core evidentialist theses but rather reflects ancillary claims that the main defenders of
evidentialism tend to hold.
2. EVIDENTALISM IN OUTLINE
I take the core thesis of evidentialism to be a claim about the relationship between evidence and
propositional justification. We can formulate it as follows:
Belief Evidentialism
A subject S is epistemically justified in believing proposition p at time t if and only if S’s evidence at t
supports believing that p.5
So construed, evidentialism is primarily a claim about propositional justification—i.e., what
justification is available (at that time) for a belief that p, regardless of whether the subject does in fact
form a belief on that evidential basis. Simply put, one’s propositional justification depends on
whether the evidential basis at that moment supports it. If the evidential basis is lacking, then
propositional justification is lacking also. Since this is a claim about propositional justification only,
then we can set aside issues of knowledge (at least given that we accept, as most do, that justified
3
true belief doesn’t amount to knowledge, and hence that forming a belief on an evidential basis that
suffices for propositional justification wouldn’t thereby guarantee you knowledge).
Notice that this core version of evidentialism is a bit weaker than the canonical version
offered in seminal works by its main proponents, Earl Conee and Richard Feldman.6 This is because
they want their version of evidentialism to not simply govern propositional justification for belief
but for doxastic attitudes more generally. We can formulate this more general thesis as follows:
Doxastic State Evidentialism
A subject S is justified in taking a doxastic attitude towards some proposition p at time t if and only if
S’s evidence at t supports the adoption of that doxastic attitude.7
One gets the general idea. Evidentialism now covers not just what beliefs would be appropriate,
given the evidence, but also what doubts would be appropriate, what suspensions of belief would be
appropriate, and so on. In what follows, for convenience, we will focus on the core evidentialist
thesis, though as we will see, nothing really turns on this—the main points we will make would apply
just as much to doxastic state evidentialism as they would to belief evidentialism.
There’s one more element of evidentialism that we need to get onto the table before we can
proceed. This is the conception of evidence in play, as that’s obviously crucial to understanding how
we are to interpret these evidentialist theses. In particular, evidence is here to be interpreted in terms
of the subject’s mental states. That is, the subject in the relevant sense ‘has’ the evidence because it is
part of her mental states. It is not enough that there simply exists objectively good evidence for the
target proposition, since were the subject to lack access to that evidence by it not being part of her
mental states (e.g., by having beliefs about that evidence, or experiences that provide evidence), then
it that won’t do the justificatory work that the evidentialist wants for their account of propositional
justification. This is the sense in which evidentialism is an internalist theory of propositional
justification, in contrast, for example, to reliabilism, which makes no such demand on evidence.8
With our understanding of evidentialism set out, let us now see how such a proposal could
be made compatible with Wittgensteinian hinge epistemology and epistemological disjunctivism.
3. EVIDENTIALISM CAN EMBRACE HINGE EPISTEMOLOGY
In his final notebooks, Wittgenstein offered a radically new conception of the structure of rational
evaluation. Naturally, there are many competing accounts of what Wittgenstein had in mind.
4
Inevitably, however, I will be offering you just my own, not only because I don’t have the space to
discuss alternative proposals, but because (of course) I think my interpretation is the correct one.9
Accordingly, henceforth when I describe Wittgenstein’s proposal, the reader should take this to
mean my specific rendering of Wittgenstein’s proposal. In addition, the reader should also note that
I will merely be describing this account, and not defending it (something that I have done at length
elsewhere).10 The point is not whether you are persuaded of the correctness of this Wittgensteinian
position, but only that evidentialism can be made compatible with such a radical proposal.
Wittgenstein’s core contention is that all rational evaluation presupposes an overarching
hinge certainty—a total and utter conviction—in the general veracity of one’s worldview. That is, it
is a requirement of even being someone who can undertake rational evaluations—who, as we might
put it, operates in the space of reasons—that one has this overarching hinge certainty in the general
veracity of their worldview. I refer to this overarching hinge certainty as the über hinge commitment.11
The reason that the über hinge commitment is a ‘hinge’ (OC, §341-43) is that it provides the
framework—the ‘scaffolding’ (OC, §211), to use another of Wittgenstein’s metaphors—on which
the practice of rational evaluation turns. Note that it immediately follows from this picture that the
über hinge commitment is an arational certainty. Since it provides the framework for rational
evaluation, it cannot be itself rationally evaluated. Indeed, Wittgenstein’s thought is that this
overarching certainty is not grounded in reason at all, but rather in action. It is a certainty that is
visceral: ‘animal’, ‘primitive’. (OC, §359, §475) We manifest our über hinge commitment in the
worldview by the way that we (ordinarily, anyway) unhesitantly act in the world, thereby revealing
our abiding certainty in the veracity of our worldview. (Wittgenstein approvingly quotes Goethe in
this respect: “In the beginning was the deed.”) (OC, §396) Relatedly, the subject doesn’t need to
have formulated in any explicit way the content of the über hinge commitment (indeed, usually they
won’t), for what is important on the Wittgensteinian account is rather how this certainty is revealed
in one’s actions. We display our deep certainty in the veracity of the worldview not by the thoughts
that we formulate, but by how our actions reveal our general confidence in the correctness of our
worldview.
Once one grants the existence of the essentially arational über hinge commitment, then a
number of interesting consequences follow. One consequence, which Wittgenstein explores at
length in On Certainty, is that there are a body of everyday commonsense certainties which effectively
inherit the visceral certainty of the über hinge commitment. Consider one’s certainty that one has
hands in normal conditions. One might think that such certainty is grounded in reasons, such as the
5
sight or feel of one’s hands. Wittgenstein offers a detailed case that this is implausible. In fact, we
could make no sense of the idea of being wrong about such a thing in normal conditions—having
hands is not like being in possession of one’s car keys, where the possibility of error is even
conceivable. The reason for this is that to be wrong about something like this in these conditions is
for one’s worldview as a whole to be in error. That is, when it comes to these everyday certainties, a
doubt here would ‘drag everything with it and plunge it into chaos.’ (OC, §613) That’s just to say, of
course, that these specific everyday certainties are effectively manifestations of the overarching über
hinge certainty. And that means that they mirror the über hinge certainty in being essentially
arational commitments, displayed in our actions rather than grounded in reasons.
Here is a second important consequence of the radical new picture of the structure of
rational evaluation that Wittgenstein is offering. On this proposal, it is in the very nature of rational
evaluation that it is essentially local. The very idea of a fully general rational evaluation, whereby one
rationally evaluates one’s commitments all at once—think, for example, of the kind of rational
evaluation that Descartes was attempting in the Meditations—is simply incoherent. In particular,
radical sceptical arguments, on this view, essentially depend on a faulty philosophical picture that
supposes that one can simply extend the scope of one’s rational evaluations without limit. Similarly,
traditional responses to radical scepticism that attempt to show that our commitments as a whole are
on a good rational footing are also problematic, as they subscribe to the same faulty philosophical
picture. Once this faulty philosophical picture is removed, then much of the impetus for radical
scepticism, and for traditional forms of anti-scepticism, disappears.
Note too a related point in this regard. One aspect of the Wittgensteinian view that many
find particularly radical is the suggestion that at the very heart of our rational practices are
commitments that are essentially arational, and hence unknown. That can feel very unsettling.12 But
if Wittgenstein is right, then the fact that we are unable to know our hinge commitments should not
be concerning to us. It is not as it one is ignorant of one’s hinge commitments, as if they are
propositions that we should know but are unable to know. That is, our lack of knowledge of our
hinge commitments is not a cognitive limitation on our parts. Just as one’s inability to picture a
circle-square does not indicate an imaginative limitation, so one’s inability to know one’s hinge
commitments does not indicate a cognitive limitation.13
Now that we have this overview of Wittgenstein’s radical hinge account of the structure of
rational evaluation on the table, we can ask whether it is compatible with evidentialism. On the face
of it, the proposal seems diametrically opposed to evidentialism, in that it allows there to be a kind
6
of commitment—an outright certainty no less—that is not rationally grounded. Evidence and
reasons are not quite the same, of course, but for our purposes we can gloss over the differences
and grant that such hinge certainties are not evidentially grounded either. But then how can it be
legitimate to have such hinge certainties from an evidentialist point of view?
A moment’s reflection reveals that this reasoning is much too quick, however. Let’s start
with belief evidentialism. The first thing to note is that this is a thesis about when a belief enjoys
propositional justification. But the whole point of Wittgenstein’s discussion of our hinge
commitments is that they are outside the realm of rational evaluation altogether, and so the question
of whether they can enjoy propositional justification simply doesn’t gain a grip here. Put another
way, on this proposal there could be no such thing as a rational (/evidential) basis such that, if we
formed our hinge certainty on this basis it would be rationally (/evidentially) grounded and hence
justified. That’s just not the kind of thing that a hinge certainty is.
Note that there is a bit of an equivocation here, as we are picking out the target proposition
qua hinge commitment, but whether a particular proposition amounts to a hinge commitment can
vary with one’s circumstances. Take the hinge commitment that one has hands. This is only
guaranteed to be a hinge commitment in normal circumstances, as there are abnormal conditions in
which it wouldn’t function in this way. If I awake in hospital after a serious car accident, for
example, then it might make perfect sense to doubt the existence of my hands and to treat my sight
of them as a rational basis for believing that they remain intact. The point is that in these particular
conditions, the über hinge commitment does not generate a specific hinge commitment in this
proposition, as it does in ordinary conditions. In these special circumstances, however, one’s belief
in this proposition could well be rationally (/evidentially) grounded, and hence there is nothing
preventing one from taking an evidentialist line on this proposition if one explicitly construes it as
not being a hinge commitment. The point thus stands that one can have hinge commitments and
belief evidentialism.
But there is more. As I have argued in my writings on hinge certainties, it is important to
specify the kind of propositional attitude in play. Contrast the folk notion of belief with a more
specific notion of belief that I will call K-apt belief (for reasons that will soon be apparent). The folk
notion of belief is notoriously permissive. It is, to use Marvin Minsky’s (2006, 2) memorable phrase,
a ‘suitcase term’, in that it covers a range of quite different propositional attitudes. Indeed, it is
arguably sufficient for belief in the folk sense that one sincerely endorses p, regardless of the manner
of that endorsement. That’s why such diverse propositional attitudes as acceptance, scientific
7
commitment, religious faith, and delusions all get characterized as (folk) beliefs. As epistemologists,
however, we implicitly restrict our attention to a more specific propositional attitude, one that has
some crucial base-level connections to reasons and truth. In particular, we are interested in that
propositional attitude that is a constituent part of knowledge. This is K-apt belief. Not all of the folk
notions of belief satisfy that restriction. We do not need to get into the reeds of this, as all that
matters for our purposes is that hinge commitments, while beliefs in the folk sense, are not K-apt
beliefs. Here is the reason why. One cannot have a K-apt belief that p while being aware that one
has no rational (/evidential) basis for regarding p as being true. Note that this doesn’t exclude the
possibility that one has a groundless K-apt belief; the point is just that one cannot be aware of this
fact. And yet hinge commitments, by their nature, are the kind of propositional attitude where one
can become aware of their groundlessness and yet this has no bearing at all on our certainty in them
(since they are not grounded in reasons at all, but rather displayed in our actions and, relatedly, our
inculcation of a worldview).14
The reason this point is important for our purposes is that it reinforces our earlier claim that
belief evidentialism is compatible with hinge epistemology. The formulation of belief evidentialism is
most plausibly understood as being concerned specifically with K-apt belief rather than the folk
conception of belief. So construed, however, then it is crystal clear that this thesis cannot have
application to our hinge commitments, as they are simply not—nor could ever be—K-apt beliefs.
Of course, modulo our earlier discussion, in changed circumstances, the very same proposition might
not function as a hinge. But that is no problem either, since in those conditions it could function as
a K-apt belief and the usual evidentialist rules will apply. So no conflict here either.
Given the foregoing, I think it also reasonably clear that doxastic state evidentialism will also
be compatible with hinge epistemology. For however these doxastic states are to be understood,
they are surely to be conceived as operating within the space of reasons, and that is a space where
hinge commitments simply do not appear. There is thus nothing preventing the proponent of
evidentialism from embracing hinge epistemology if they wish, on either version of the thesis.
4. EVIDENTIALISM CAN EMBRACE EPISTEMOLOGICAL DISJUNCTIVISM
Perhaps an even more surprising result is that evidentialism is compatible with epistemological
disjunctivism. This is the proposal, which I take to be rooted in the work of McDowell (e.g., 1995),
8
that in paradigm cases of perceptual knowledge that knowledge is grounded in rational support that
is both reflectively accessible and factive.15 This is a controversial thesis on account of the fact that
reflectively accessible perceptual reasons are usually taken to be essentially non-factive. In contrast,
epistemological disjunctivism takes our ordinary language talk in this regard, which is shot-through
with factive reasons, at face-value.
For example, take the factive locution of seeing that p. If one sees that p, then it follows that p
must be true (compare seeming to see that p, which is not factive). If one sees that there is a barn in
front of you, then there is a barn in front of you. We use this factive locution as a reason all the time
in everyday life. Imagine the following scenario. Your boss calls into work and expresses scepticism
when you say that a co-worker is in the office. It would make perfect sense to say that you know
that they are here because you can see that they are in the office. In contrast, it would be very odd in
these circumstances, with the co-worker standing right before you, to say that it merely seems to you
as if the co-worker is in the office (which is a non-factive locution).
Of course, there are various philosophical reasons why philosophers opt to re-interpret these
ordinary factive locutions into non-factive terms, but epistemological disjunctivism provides the
resources to resist this reinterpretation. Recall that in his defence of hinge commitments
Wittgenstein offered us a way of making sense of our ordinary epistemic practices that incorporated
a picture that was alien to the prevailing philosophical orthodoxy. In the same spirit, epistemological
disjunctivism offers us a way of making sense of our ordinary epistemic practices involving factive
reasons. In particular, it argues that there are no good reasons for treating such factive reasons as
problematic; they can be reflectively accessible just as one’s other reasons can be. As with the
Wittgensteinian position, my goal here is not to convince the reader of the plausibility of
epistemological disjunctivism, so it would be beside the point to get into the details of this proposal.
All that matters for our purposes is that this is an unorthodox epistemological proposal.
Nonetheless, it is a proposal that is entirely consistent with evidentialism.
As with our discussion of hinge epistemology, epistemological disjunctivism trades in
reasons rather than evidence, so we will need to gloss over the distinction (which, again, doesn’t
matter much for our purposes anyway).16 With this caveat in mind, we can start to see how
epistemological disjunctivism might be compatible with evidentialism. I noted earlier that
evidentialism incorporates a particular conception of evidence cast in terms of the subject’s mental
states. It is usually taken as given by proponents of evidentialism, in accordance with philosophical
orthodoxy, that one’s reflective accessible mental states provide non-factive evidential support for
9
one’s beliefs. So insofar as I can reflectively access the rational support for my belief that p, then it
must be of the form that it seems to me that p as opposed to that I see that p. But this is precisely
what epistemological disjunctivism denies. One can have reflective access to factive mental states,
which in turn can function as reasons.
With this broadened notion of evidence—and, relatedly, of what counts as one’s mental
states—in play, then one can reinterpret evidentialism in ways that can accommodate
epistemological disjunctivism. Take belief evidentialism, for example. This refers to one’s evidence
offering propositional support for one’s belief, and we’ve noted that by evidence the evidentialist
means something connected to the subject’s mental states. But if epistemological disjunctivism is
correct, then that’s perfectly consistent with the idea that one’s evidence could be factive.
The same applies to the stronger evidentialist thesis of doxastic state evidentialism.
Remember that epistemological disjunctivism is only a thesis about the rational (/evidential) support
enjoyed by one’s perceptual beliefs in paradigm cases. It follows that we don’t need to worry about
different kinds of doxastic states and the propositional justification they might enjoy; all that matters
is the epistemic support that perceptual beliefs enjoy in paradigm cases. Essentially, what the
reworking of evidentialism in terms of epistemological disjunctivism would entail is that in these
very specific conditions the evidential support for one’s propositional justification would be factive
in virtue of the evidential ground that one sees that such-and-such is the case.17
5. CONCLUDING REMARKS
One might naturally ask what the point of all this is. It is, I think, fairly obvious that the main
proponents of evidentialism will not endorse hinge epistemology or epistemological disjunctivism.
Indeed, I think they would find both views quite preposterous (and since I have not been concerned
to defend these theses, but merely to describe them, I haven’t done anything to mitigate this
tendency). My interest, however, on this anniversary of evidentialism, has been irenic. If I am right,
then the traditional picture of evidentialism as being an inherently epistemologically conservative
proposal is wrong. In fact, evidentialism, properly conceived, is compatible with some quite radical
contemporary epistemological proposals. In particular, insofar as evidentialism is a conservative
position, this does not reflect its nature, but rather the ancillary commitments of its main
proponents. That’s a good result for evidentialism, and certainly one to applaud on its anniversary.18

For some of the key texts on virtue epistemology, see Sosa (1991; 2007; 2009; 2015; 2020), Zagzebski (1996), and
Greco (2010). Anti-risk virtue epistemology (previously called anti-luck virtue epistemology) is my own preferred account of
knowledge—see Pritchard, Millar & Haddock (2010, chs. 1-4) and Pritchard (2012a; 2016; 2020a).
2 I suspect that this volume will represent all the main objections to evidentialism, which is why I will not set out my
concerns with the position here, as they are not original to me. Better instead to concentrate on the more interesting—
and, I think, largely positive—claim that I want to make about evidentialism.
3 See Wittgenstein (1969). Henceforth ‘OC’.
4 See, especially, Pritchard (2012b; 2015).
5 For helpful discussion of this core evidentialist thesis, see Mittag (2010; 2024). Note that henceforth I am going to
treat the notion of justification in play to be obviously epistemic, and so drop the qualifier.
6 See, especially, Feldman & Conee (1985; 2001) and Conee & Feldman (2004).
7 See, for example, Feldman & Conee (1985, 15). Feldman and Conee in fact talk about the doxastic attitude ‘fitting’ the
subject’s ‘total evidence’, but I don’t think this materially changes things.

Pritchard (2017) and Moyal-Sharrock & Pritchard (forthcoming).
10 See, especially, Pritchard (2015).
11 See especially Pritchard (2015, part 2). Note that since the über hinge commitment concerns the general veracity of
one’s worldview, then it involves a certainty that one is not the victim of radical sceptical hypotheses. While this is a
consequence of the über hinge commitment, however, it would be misleading, as we will see, to put too much emphasis
on this point in our exegesis of Wittgenstein’s views. This is because his main concern is rather showing how some of
the most mundane commonsense commitments that we have, such as that one hands (in. normal conditions), are
effectively manifestations of the über hinge commitment (in that doubt here would call one’s worldview as a whole into
question).
12 Indeed, as I’ve argued, in a Cavellian spirit, it is unsettling, but not unsettling in a way that is related to the problem of
radical scepticism. What is at issue here is what I refer to as epistemic vertigo, which is a very different kind of epistemic
angst than that in play in the radical sceptical problematic. See Pritchard (2020b; 2021a; 2024a).
13 Other conceptions of our hinge commitments might well have this consequence, especially that offered by Wright
(2004), who explicitly casts our hinge commitments in terms of a general cognitive limitation. For discussion of this
specific issue, see Pritchard (2023). On the idea that ignorance is not just lack of knowledge (or true belief), but also
involves a normative component, in the sense that ignorance is failing to be aware of what one ought to be aware of (the
normative account of ignorance), see Pritchard (2021b; 2021c).
14 This is the sense in which becoming aware of the hinge nature of this commitment (something that is not normally
apparent in everyday life), can feel uncanny. This is what gives rise to the epistemic vertigo—see endnote 12. For further
discussion of the distinction between folk belief and K-apt belief, see Pritchard (2015, part 2; 2018; forthcoming). For
further discussion of different ways of classifying our belief talk, see Stevenson (2002).
15 I develop this thesis in detail in Pritchard (2012b). See also Pritchard (2015, passim).
16 I discuss how to think of epistemological disjunctivism in terms of evidence in Pritchard (2010; 2024b).
17 Insofar as evidentialism is compatible with epistemological disjunctivism, then I think it is also likely to be compatible
with another radical proposal in the general vicinity of epistemological disjunctivism—viz., knowledge-first epistemology,
of the kind defended by Williamson (2000). Indeed, given that Williamson himself defends the claims that (i) knowledge
is identical with evidence, and (ii) knowledge is a mental state, it should be relatively straightforward to articulate an
evidentialist position that embraces knowledge-first epistemology. (I gather that Fratantonio (forthcoming), which also
appears in this volume, defends a knowledge-first version of evidentialism).
18 I am grateful to Kevin McCain for detailed comments on an earlier version of this paper.
