Abstract
We use the term “good” in two contexts: as the most general term of evaluation, and
to refer to the final ends of life and action. I start from the question what evaluative
and final goodness have to do with each other. Do we use the same term because when
we talk about final goods, we are evaluating ends and lives? If so, how do we go about
doing that? Most things are evaluated with respect to their fitness to perform their
function, but ends and lives do not have functions. I contrast three theories of the final
good: the intrinsic value theory, the hedonist theory, and Aristotle’s account, which
identifies a being’s final good with its well-functioning, a form of evaluative goodness.
Aristotle’s theory suggests an illuminating relationship between evaluative and final
goodness: a conscious being has a final good when she functions by having conscious
states that track, and so enable her to pursue, her functional or evaluative goodness. It
is therefore the nature of an animal to have a final good, and there are such things as
final goods because there are animals. This theory explains the existence of final goods
without any metaphysical appeal to intrinsic values.

The Origin of the Good and Our Animal Nature / Christine M. Korsgaard
I. Introduction
This paper is part of a larger project in which I investigate the origins of value.
Those who believe that there are intrinsic values—that some objects, activities, or
entities simply have the property of being valuable—do not feel a need to answer
questions about the origins of value. For them, value is just there. But I believe that
all value is dependent on the existence of valuing beings. In this paper, I am going
to defend an account of the good, derived from Aristotle, that grounds it in our
animal nature, and explain why I think this view is superior to some of its rivals.
One reason I think it is superior is that it enables us to explain why there is such a
thing as the good.
II. A Puzzle about the Good
I want to begin my discussion by noticing something that I think we should find
puzzling about our use of the concept “good.” The term “good” is used in two
broadly different ways. First, “good” is our most general term of evaluation, a term
we apply to nearly every kind of thing, or at least every kind of thing for which we
have any use, or interact with. Think of the wide variety of things we evaluate as
good or bad: cars, houses, machines and instruments, food, weather, days, prose,
pictures, movies, people considered as occupying roles such as mother, teacher,
son, doctor, and people considered just as people, among many other things. All of
these things may be evaluated as good or bad. Evaluation is usually related to the
purpose, role, or function of the entity that is judged good or bad: an entity is good
in the evaluative sense when it has the properties that enable it to serve its
function—either its usual or natural function or one we have assigned to it for some
specific purpose. I will call that the evaluative good.
I call “good” in the second sense in which we use the term the final good,
borrowing one familiar translation of the Greek word “telos”. Final goods are the
ends of action. We suppose that something we call “The Good” is the end or aim of
all our strivings, the summum bonum, a state of affairs that is desirable or valuable
for its own sake. We are usually talking about a person’s final good when we speak
of what is good for that person. That is, the things that are good or bad for a person
are things that have an impact on his final good. We sometimes call our own final
good “the human good”, suggesting that things other than human beings have a

final good of their own, and perhaps also that the good for a thing is relative to its
nature.
The puzzle is simply this: what is the relation between the evaluative and the
final sense of good? Why do we use the same word as a general term of positive
evaluation, and to designate the final ends of our lives and actions? I think that
most people do not find this puzzling because they think that the answer is obvious:
when we talk about someone’s final good, we are still using the term evaluatively:
we are evaluating the person’s life. I do not mean we are evaluating it morally. That
would be an evaluation of the person himself. Rather, we are evaluating something
about how the life goes and the total circumstances in which it is lived.
It is tempting to say that we are evaluating the quality of a person’s life. But the
phrase “evaluating the quality” just says the same thing twice over, namely, that his
life is a proper subject of evaluation, it is the sort of thing that can be of a high or
low quality. But that is exactly the problem. Ordinarily, as I mentioned earlier, we
evaluate things by asking whether they have the properties that enable them to
perform their function, but a person’s life and circumstances, considered just as
such, do not seem to have a function. So how do we go about evaluating them? If
we ask whether, say, a car is good, we are asking whether it has the properties that
enable cars to perform their function well: whether it handles well, gets good gas
mileage, is safe, and things like that. But when we ask whether a person’s life is
good, we do not seem to be asking anything except whether the person whose life
it is achieves that thing we call “The Good”. This becomes particularly obvious if we
want to leave open the possibility that the human good is something that is in a
certain way external to life itself—the way it is on some conceptions of, say, nirvana,
or salvation. People who believe in such final goods do believe that human life has
a purpose, but that purpose seems to be to enable us to achieve that thing we call
“The Good”. But then what are we evaluating when we talk about “The Good”?
One might be tempted to answer that we are evaluating possible ends: things we
might pursue for their own sake. But then what is the function of an end—or, perhaps
to put it more intelligibly, what makes something fit to be an end? Apparently, that
it is something good for its own sake, or finally good. This is the kind of consideration
that drove G. E. Moore to the view that there simply nothing we can say about the
good except that it is good, in just the same way that there is nothing we can say
10
The Origin of the Good and Our Animal Nature / Christine M. Korsgaard
about red except that it is red: it is just a property.1 It follows from Moore’s theory
that there is no way we can know what is good in the final sense except by a power of
rational intuition that functions like a sense. If Moore is right, there is no point in
trying to identify the human good through philosophical argument: we just have to
focus our powers of intuition. But I believe that the puzzle has an answer, and that
the situation is not as hopeless as Moore made it seem.
III. Three Theories of the Good
I will come back to the puzzle, but first I want to describe three theories of the final
good I am going to canvass in my search for an answer, and note where they stand
on a certain question: namely, whether and how the final good for a being is relative
to its nature. According to what I will call the intrinsic value theory—this is
essentially G. E. Moore’s theory—certain objects, states of affairs, activities, or
forms of experience have the property of being intrinsically valuable. On this
theory, it is natural to suppose that the good for a sentient being consists in
exercising his ability to experience, appreciate, or participate in these intrinsically
valuable things. According to this view, the good for such a being is relative to his
nature, but only in the sense that his nature determines which kinds of intrinsic
value he is able to experience, appreciate, or participate in. The human good is a
richer thing than the good for a non-human animal, because our nature enables us
to enjoy the objective values of art, literature, science, philosophy, and humor, say,
while another animal’s nature might enable her to enjoy only such simple intrinsic
values as pleasurable experience, family affection, and so on. We can intelligibly
say that it is better to be a human being than to be another sort of animal, since
human beings get to participate in a wider range of intrinsically valuable activities.
Plants and inanimate objects, on this view, do not have a final good at all since they
are unable to participate in valuable activities or have valuable experiences.
According to the second view I will consider, hedonism, the good just is
pleasurable experience or consciousness and the absence of painful experience or
consciousness. What makes a being capable of having a final good is simply that
the being is conscious and can experience pleasure and pain. Otherwise, her good
is not relative to her nature. On this theory it is a real question whether some of the
1. In: G. E. Moore, Principia Ethica (1903).
The Journal of Ethical Reflections, Summer, 2020, 1 (2)
11
other animals might not have a better life, or at least be capable of having a better
life, than human beings, given their apparent enthusiasm for simple and readily
available joys. Although I will treat it as a separate theory, hedonism, I believe, has
an inherent tendency to collapse either into a version of the intrinsic value theory,
or into a version of the third view I am about to describe. Obviously, it is possible
to regard hedonism simply as a particular instance of the intrinsic value theory, one
that singles out conscious experience as the only possible bearer of intrinsic value.
But I think this way of looking at hedonism does not do justice to the intuition that
has made hedonism seem plausible to so many thinkers, which is precisely the idea
that the final good must have an irreducibly subjective or relational element. That
is, what makes hedonism seem plausible is precisely the idea that the final good for
a sentient being must be something that can be felt or experienced as a good by
that being. It is something that can be perceived or experienced as welcome or
positive from the being’s own point of view, and that is therefore relative to the
being’s own point of view. The intrinsic value version of hedonism tries to capture
the essentially subjective element of the final good by attaching objective intrinsic
value to a subjective experience, but when this move is made the essentially
relational or relative character of subjectivity tends to drop out. The goodness of
the experience is detached from its goodness for the being who is having the
experience, and instead is located in the character of the experience itself. This
defect shows up most clearly in utilitarian versions of hedonism, which allow us to
add the goodness of pleasant experiences across the boundaries between persons
or between animals. There is no subject for whom the total of these aggregated
experiences is a good, so the aggregate good has completely lost its relational
character: the goods are detached from the beings for whom they are good. This
relational element of value, I believe, is better captured by the third theory I am
about to describe.
The third view, and the one I wish to defend, is a version of the account
suggested by Aristotle’s famous function argument in Section Seven of Book One
of the Nicomachean Ethics. Aristotle says:
Presumably, however, to say that happiness is the chief good seems a
platitude, and a clearer account of what it is is still desired. This might
perhaps be given, if we could first ascertain the function of man. For just as
for a flute-player, a sculptor, or any artist, and in general, for all things that
12
The Origin of the Good and Our Animal Nature / Christine M. Korsgaard
have a function or activity, the good and the ‘well’ is thought to reside in the
function, so it would seem to be for man, if he has a function (Aristotle, NE,
1.7, 1098a, pp. 22-29).
Aristotle’s point is not that human life has a purpose and our good rests in
serving that purpose.1 Rather, characterizing the view in an abstract and somewhat
cumbersome way, Aristotle’s idea is that the good for a being consists in the wellfunctioning of that being as the kind of being that it is, in circumstances that are
conducive or favorable to its overall well-functioning. I will make this idea less
abstract later on.
Now Aristotle’s view, like the hedonist view, could conceivably be reduced to a
version of the intrinsic value theory. We could say either that the well-functioning
of a sentient being has intrinsic value, or that a sentient being is well-functioning
when he participates in whatever intrinsically valuable activities his nature makes
possible for him. But I think Aristotle’s view is more interesting if we combine it
with a Kantian approach to value, which makes all values relative to what we might
broadly call our valuing capacities: the capacity to find something pleasant,
interesting, enchanting, satisfying, or stimulating—and of course to experience the
opposite responses as well. Sticking to the human case for now, according to this
view, what makes a state of affairs or an object or an experience valuable is precisely
its capacity for eliciting joy, interest, or appreciation from human beings, together
with the value that, according to Kant, we necessarily set upon our humanity itself.
Science and philosophy are valuable for human beings because they engage and
arouse the intellectual faculties of human beings. Art and music are valuable for
human beings because of their capacity to elicit complex and satisfying perceptual
experiences refined by thought and emotion. Fine food and wines are valuable for
human beings because of our capacity to aestheticize the appetites we share with
the other animals. Love and friendship are valuable because of the human social
needs they satisfy and the human powers they arouse in us. And so on. If we ask
why we treat the things that are good for human beings as finally good, as valuable
for their own sakes, Kant’s answer, given by his argument for the Formula of
Humanity, is that we take these things to be valuable because of the value that we
necessarily place on ourselves. To take what is important to you to be important,
1. See my “Aristotle’s Function Argument” (2008) for further defense.
The Journal of Ethical Reflections, Summer, 2020, 1 (2)
13
period, is just what it means to place a value on yourself.1 And to render these values
normative is, accordingly, to express the value you place on yourself and on
humanity generally, by willing these values as laws. So what makes our wellfunctioning good is not that it has intrinsic value, or that it consists in the pursuit
of intrinsic value, but rather that we ourselves value it and confer normativity upon
it by willing it as a law that this value should be realized. In what follows I will be
arguing that we have to do that, because of our animal nature.
According to this Aristotelian theory, values are relative to a being’s nature. It
is good for a human being to philosophize or explore nature or fall in love in just
the same way it is good for a horse to run, or a whale to breach, or for a tiger to
hunt, or for an insect to pollinate its characteristic plant—because that is the
fulfillment or realization of an animal’s nature—because that is how he functions.
On this view, interestingly, we cannot say that it is better to be a human being than
to be another kind of animal, or if we can, it can only be with reference to kinds of
goods that we share with the other animals—to the goods that pertain to our animal
nature as such, rather than to specifically human goods.
IV. The Nature and Content of the Good
Before I continue, I want to mention two other theories of the final good commonly
discussed in the literature, namely perfectionism and eudaimonism, and explain
why I am not discussing them here. This will give me an opportunity to clarify
something about the nature of the question I am trying to raise.
As the translation of the passage from Aristotle I just quoted suggests, people
often identify the good with happiness. The theory that happiness is the good is
sometimes called eudaimonism, from the Greek word that gets translated
“happiness” here—eudaimonia. One reason I will not be discussing the view that
the good is happiness here is that the notion of happiness is almost as obscure as
the notion of the final good. In fact, we can interpret “happiness” so broadly that it
means pretty much the same thing as the final good—although with a nod towards
the subjective element in that idea that I have already mentioned in connection
with hedonism. On the other hand, if we interpret “happiness” so that it means

of Normativity, (1996 b), §§ 3.4.5-3.4.9, pp. 117-123.
14
The Origin of the Good and Our Animal Nature / Christine M. Korsgaard
something more specific than that, then the theory that happiness is the good is not
a theory of the good in the sense that I am talking about here, as I will explain in a
moment. Aristotle’s view is also often classified as a version of what is called
“perfectionism,” the view that the good for a human being rests in the development
or realization of human capacities.1 On the assumption that a thing’s wellfunctioning is expressed in the realization of its natural capacities, it makes sense
to attribute this to Aristotle. But some perfectionists seem to have a further idea in
mind—one of using our capacities and powers to the fullest, or maximizing their
use or something like that. It is not really clear why the bare idea of wellfunctioning should involve the idea of using one’s powers to the fullest. However
that may be, there is a reason I have not included these two theories among my
candidates, although this reason is a little difficult to explain. These theories are
most naturally understood as theories about the content of the finally good—about
what in particular is finally good. Whereas I am looking for an account of what the
good is that would enable us to pick out its content, one that would enable us to say
which things are good and explain why they are, or at least to say how we would go
about picking which things are good. I might say that what I am asking about in
this paper is not the content of the good, but the nature of the good, on the
assumption that if we knew what sort of thing the good is, we would be able to apply
that knowledge to discover which things are good. The distinction is clearer in some
theories than others, and Moore’s theory enables me to show you what I have in
mind. Moore’s theory about the nature of the good is that it is an intrinsic property,
discerned by intuition. His theory about its content is that consists in aesthetic
experience, friendship, knowledge, and so on. Now, in spelling out my three
theories, I mentioned that either Aristotle’s theory or hedonism may be regarded
as applications of the intrinsic value theory, that is, claims about which things have
intrinsic value, and so as claims about the content of the good. But I am treating
these theories as theories about the nature of the good.
That this sort of slippage is possible, I think, shows that philosophers do not
usually make a very firm distinction between views about the nature of the good
1. The term “perfectionism” is also used to characterize certain moral theories, generally
theories which take the goal of moral action to be the maximizing or promoting of the
human good in the perfectionist sense. I am only talking about perfectionism as a theory
of the good here.
The Journal of Ethical Reflections, Summer, 2020, 1 (2)
15
and views about the content of the good. But this is no accident, because the
difficulty of making this distinction is reflected in the puzzle itself. If we do not
know what exactly we are evaluating or how exactly we are evaluating it when we
claim something is good in the final sense of good, it is not surprising that we
cannot firmly distinguish between talking about the nature of the good and merely
identifying its content. Most of the time, we know what we are doing when we
identify something as evaluatively good. I want to know what we are doing when
we identify something as finally good.
The fact that I am looking for a theory of the nature of the good in the sense I
have just tried to explain will make the fact that I have included hedonism on my
list seem peculiar, for surely it is most naturally interpreted as a theory of the
content of the good. I have included it because I think, for reasons already
mentioned, that it captures something important about the nature of the good—
namely, the subjective and relational aspect of the good. As for Aristotle, explaining
his account as an account of the nature of the good will be the work of the rest of
this essay.
In fact, I hope you will not be too disappointed to learn that for purposes of this
essay I am not going to say much at all about the content of the human good. I will
take it for granted that any of these accounts might plausibly pick out the sorts of
activities, experiences, and achievements that most of us are tempted to think must
constitute the human good—love, knowledge, participation in social and civic life,
intellectual and aesthetic experiences and activities, standing in a proper
relationship to humanity and nature, moral virtue, significant achievement—all the
usual things. Such things might be taken to be intrinsically valuable, or the sources
of our deepest and steadiest pleasures, or the manifestations of the wellfunctioning of our nature, depending on which theory is correct. My interest is
rather in the metaphysical question what sort of thing we are talking about when
we talk about the final good for a certain kind of being.
V. The Metaphysical Background to Aristotle’s Theory
I am interested in Aristotle’s view because it represents an interesting way of
relating the evaluative and the final senses of good. Earlier I mentioned the view
that we use the same term for the evaluative and final good because talk of the final
16
The Origin of the Good and Our Animal Nature / Christine M. Korsgaard
good involves the evaluation of a life. According to Aristotle’s view, we also use the
same term because both the evaluative and the final good are matters of wellfunctioning. To say that something is evaluatively good is to say that it has the
properties that make for well-functioning, and to say that something achieves its
final good is to say that it in fact functions well. Importantly, though, we should say
it achieves the final good not merely when it functions as well as it can, given the
circumstances, whatever they are, but when it functions well in circumstances that
allow or and perhaps even facilitate its functioning well.
However, this is all very abstract, and in order to make it less so, it will be
necessary for me to say a little about the metaphysical conception behind it.
According to Aristotle, any substance or entity has a function. This is because
according to Aristotle, a substance or an entity is matter so organized as to serve
some purpose or function, to do something. Specifically, every entity can be
analyzed as a form in a matter. The matter is the material or parts of which the
entity is composed, while the form is the arrangement of the matter or the parts
that enables the entity to serve its purpose, or to do whatever it characteristically
does. Of course, the idea is clearest in the case of an artifact or a machine. A car is,
say, engine, gas tank, chassis, wheels, etc. organized in such a way as to form a
guidable means of human transport, or something like that. The engine, gas tank,
chassis, wheels, and so on are the matter or the parts; the form is that arrangement
of those parts that enables the car to serve as a guidable means of human transport.
In the case of an artifact, we identify the function or purpose of the entity in
question by reference to our own purposes or that of its inventor.
Aristotle extended this basic idea—that a substance is a functionally organized
unity—to living things by means of a thesis about what a living thing essentially is.
A living thing is a substance so arranged as to secure the continuing existence of its
own form. It does this in two ways: through nutrition, which enables it to preserve
a continuing spacio-temporal stream of matter in its own arrangement or form,
and through reproduction, which enables it to impose its form on other bits of
matter. In other words, a living thing has a form that maintains matter in that very
form. That is its function. A living thing functions well, essentially, when it manages
to stay alive and reproduce. This metaphysical thesis does not imply that living
things, like artifacts, were created by a designer for the purpose of preserving
The Journal of Ethical Reflections, Summer, 2020, 1 (2)
17
themselves and their forms. Instead, it simply asserts that that is what a living thing
is. We identify a certain bit of matter as a living thing or organism when it is so
organized as to preserve its own form in these ways, when it has a self-maintaining
form.
Each kind of organism has its own specific ways of carrying out its nutritive and
reproductive activities, or its own form of life. We can identify it simply as the
substance or entity that leads that form of life, or whose matter is organized in such
a way that it maintains its form by living that form of life. Thus a dandelion is an
entity that maintains its form through dandelion activities, such as spreading
dandelion seeds on the wind, and a porcupine is an entity that maintains its form
through porcupine activities such as defending itself with quills. In each case the
function of the entity is simply to be what it is, to lead the kind of life it
characteristically lives.
But we can also draw broad distinctions among types of life forms. Plants are
the basic form of living organism, characterized simply by the powers of nutrition
and reproduction. Animals, as Aristotle understands them, are characterized by an
additional set of powers that determine the way they carry out the nutritive and
reproductive functions—namely, the powers of perception and action, where action
is understood basically as locomotion guided by perception. The idea of an animal,
as Aristotle understands it, is the idea of an entity that preserves her form in part
through her consciousness of her environment, and her resulting ability to respond
to her environment in ways that serve to maintain her form. The idea is not, of
course, that the animal aims at the preservation of her form, if that is understood
to mean that the animal consciously entertains such an end. Rather, the idea is that
the way an animal functions is by having instinctive evaluative attitudes—desire
and aversion, pleasure and pain, fear and interest—towards things that affect her
functioning. Although I am obviously using the notion of an evaluative attitude very
broadly, it may seem extravagant to ascribe evaluative attitudes of any kind to
simpler animals. But I think that an animal’s experiences must, at some level,
however primitively, be aversive or welcome, in order to play a role in the animal’s
self-maintenance at all. If her perceptions are to guide her towards what she needs
and away from what threatens her, they must render some things attractive and
some repulsive. That is still an evaluative state, and that is all that the argument
18
The Origin of the Good and Our Animal Nature / Christine M. Korsgaard
will require.
I should note that the Aristotelian categories of plant and animal are not
precisely coextensive with the contemporary scientific use of the terms: an animal
now is understood to be, very roughly speaking, a complex, multicellular organism
that feeds on other organisms, as opposed to plants that can convert sunlight or
perhaps methane into energy. Nowadays scientists believe that some organisms,
such as fungi, do not fit into either of these categories, and some animals, such as
sponges, do not fit Aristotle’s definition very well. But of course there is broad
overlap between Aristotle’s categories and the modern one, and it is no accident.
While it is not necessary that a creature that feeds on other life forms be percipient
and mobile, that is how most kinds of animals function. In any case, it is animals
in Aristotle’s sense that I am talking about when I talk about animals in this paper:
beings who are guided by their evaluative attitudes to respond with appropriate
actions to events in their environment, and who in that way preserve and maintain
their forms.
Because he has the powers that make agency possible, Aristotle believed, an
animal lives or has a life in a sense that a plant does not.1 Animals have experiences
and they act, they do things, in a sense that plants do not: it is natural for us to
describe animals, even fairly primitive ones, as hunting, eating, mating, defending
themselves, raising their young. But the capacities for feeling and action are not
just powers added, so to speak, on top of the animal’s nutritive and reproductive
life. They are powers that exist in the first instance as a way the way the animal
carries out the tasks of nutrition and reproduction that an animal shares with
plants. The animal’s capacity for action shapes the way she gets food and produces
offspring. However, as a result of having these powers animals also do things that
plants do not do at all—they enjoy and suffer from their lives, and as a result they
may do other things that plants do not do, like, say, loving, or playing. These facts
make the “life” of an animal a different sort of thing than the “life” of a plant.
Aristotle thought that human beings, as rational animals, formed a distinct,
third kind of being, with a third kind of life. I will not attempt to say here what
Aristotle understands by “rationality.” But his idea is that the capacity for
1. Aristotle refers to various senses of “life” (“the life of nutrition and growth” “the life of
perception” “an active life of the element that has a rational principle”) in the function argument,
in the argument following the lines I quoted earlier (Aristotle, NE, I.7, 1097b 20-1098a 5).
The Journal of Ethical Reflections, Summer, 2020, 1 (2)
19
rationality changes the way we carry out the functions we share with the other
animals, just as the capacity for action changes the way animals carry out the
functions they share with plants. And, as in that case, it also adds to our repertoire
of activities, expanding those to include such purely human activities as, say, the
disinterested pursuit of knowledge and aesthetic activities. But the main change is
that with rationality comes the power of choice, in a distinctive sense not shared by
the other animals. For a non-human animal’s way of life is mapped out for her, at
least broadly, by her instincts; and any two members of a given animal species
basically live the same sort of life (unless the differences are biologically fixed, as
by age and gender, or by kinds as among bees). A human being, as a rational being,
therefore has a life in a different sense from this, for a human being has, and is
capable of choosing, what we sometimes call a “way of life.” Thus rational nature,
or personhood, introduces a new a form of functioning, and so a new form of life.
VI. Health and Goodness: Some Objections
In fact, this last consideration points in the direction of an answer to a possible
objection to Aristotle’s theory. By now it should be obvious that Aristotle’s theory
suggests that the final good for an organism is essentially to be healthy—more
properly speaking, to lead a healthy life of its kind in circumstances favorable to its
leading such a life and continuing to lead such a life. And while that may be a
plausible thing to say about the good for a plant or an animal, it may seem to be too
thin as an account of the human good. But as I have just explained, it is part of
Aristotle’s view that, in virtue of rationality, human beings have a life in a sense
that animals do not. The well-functioning that constitutes the human good is wellfunctioning in the specific kind of life made possible by the capacity for rational
choice. It would take me too far afield to defend this claim now, so for now I will
just assert that what it is to be well-functioning in that form of life is not merely a
matter of health, at least as we ordinarily understand the idea of health.
But there is one ramification of Aristotle’s theory of the human good that is
worth mentioning. According to the other two theories of the good I have described,
whether there is any connection between being a good person in the evaluative
sense and achieving the final good seems to be an open question. Of course, among
the circumstances that are part of the final good for an entity might be some that
20
The Origin of the Good and Our Animal Nature / Christine M. Korsgaard
require that she have certain evaluatively good attributes, but whether this is so
and which attributes are required is an empirical matter, or at any rate one to be
settled by further argument. Suppose that human beings are good in the evaluative
sense when we are morally virtuous. Whether that promotes our ability to
participate in intrinsically valuable activities or to have pleasurable experiences is
an open question. But in Aristotle’s theory, the connection between being good in
the evaluative sense and achieving the good in the final sense is not merely an
empirical one, because both kinds of good essentially involve well-functioning. If
Aristotle is correct in thinking both that moral virtue is essential to human wellfunctioning—of course that is a very big “if”—and if he is correct in thinking that
the final good is to be a well-functioning member of your kind, it will fall out as a
kind of necessary truth that virtue is essential to the achievement of the good. 1
Before I go on, I want to mention some other objections to Aristotle’s view that
are connected to the fact that the good for an organism, considered as such, is to
lead a healthy life. These objections have to do with the way we talk. I have claimed
that a thing is good in the evaluative sense when it has the properties that enable it
to perform its function well. But we do not usually call a plant or an animal “good”
in virtue of being healthy. We might say that a healthy animal is a good specimen,
but when we speak that way we are not talking merely about the fact that he is
healthy—rather, we are talking about the fact that his health makes him useful to
us in some way, say as an object of study, or as breeding livestock. And that brings
me to the other side of this objection. We do tend to describe living entities as
evaluatively good when they have properties that enable them to serve our own
purposes. As we tend to use the evaluative notion, a good horse is one good for
riding, good corn is corn good for the eating, and, if you would believe the
caretakers of suburban lawns, the only good dandelion is a dead one. As we
normally use the terms, then, we would not call a well-functioning dandelion good,
and what we would call, say, “good corn” does not necessarily have the properties
that make a corn plant flourish. It seems conceptually possible, for instance, that
the sweetest corn, best for the eating, might fail to reproduce well, or something
like that.

good.

I do not think that either of these facts about the way we talk should worry us.
Although we do not call healthy animals “good” ones in virtue of their health, there
is an obvious continuity between a well-functioning artifact and a healthy animal:
both have the properties that enable them to do what they do successfully. But I
will sometimes call “good” in the sense of having properties that make a thing wellfunctioning of its kind the “extended-evaluative” sense, to remind you that it
includes both the ordinary evaluative sense and the organic idea of being healthy.
This is reflected in the fact that the ordinary evaluative sense of good and the idea
of being healthy seem to support the notion of “good for” and “bad for” in similar
ways. Fatty foods are bad for you, and impure gasoline is bad for your car. That is
suggestive, because this use of “good for” provides an apparent link between
goodness in this extended-evaluative sense and goodness in the final sense. In fact,
the idea of health in general seems interestingly poised between the evaluative and
the final sense of goodness. For to say that an organism is healthy is clearly to
evaluate how well it is functioning, and yet most of us would agree that health is at
least an important part of the final good—and perhaps nearly the whole of it for
some of the other animals.
As for the other side of the linguistic awkwardness—that the organisms we do
call “good” are not necessarily healthy and thriving—that is no problem at all. That
simply reflects our own tendency to regard plants and animals as instruments, and
to evaluate them as if they were a kind of artifact created for our use. And even
though we do that, we do not usually go so far as to talk about what is “good for”
say, plants, with reference to the ways in which plants are good for us; rather, we
use it to refer to their own well-functioning. So, for instance, we might note with
regret that the fertilizer we are using is just as good for the weeds as it is for the
grass. Aristotle’s view that a thing’s final good is its own well-functioning actually
explains why we can say this sort of thing, and why we say it in the case of living
entities but not artifacts. Since an artifact exists and has a function only with
reference to us and our needs, there is no real room for opposition between its good
and our own. But because a plant’s function is defined with reference to its
maintenance of its own form, to its ability to lead its own distinctive kind of life,
such an opposition is possible: what is good for it may not be good from our point
of view.

VII. What Kinds of Things Have a Final Good?
But is goodness in the extended-evaluative sense connected to final goodness in the
way Aristotle supposes? Some of you are probably already growing restive under
the idea, vaguely implied by what I have just been saying, that there is such a thing
as a “final good” for, say, a car. We certainly do say that it is good for the car to drive
it once in a while, meaning that driving the car regularly keeps it functional. But we
do not really think of a car as having a final good: nothing that happens to it is really
for the sake of the car: usually, it is for the sake of the car’s owner. We think of only
certain kinds of beings as having a final good, while the notion of well-functioning
extends much more widely. Indeed, according to Aristotle’s metaphysics, it extends
pretty much to anything we can recognize as an entity at all.1 But I do not think this
is as grave a problem for Aristotle’s view as we might at first think, for reasons I
have already touched on in the discussion above. The good for an artifact is wholly
relative to the good of the being who will use it. In fact, sometimes when we talk
about what is “good for” an artifact, it is fundamentally unclear whether we are
really talking about something that enables it to perform its function, or something
that would give it other properties we would like it to have. This is because it is
fundamentally unclear whether we should count, as part of its function, its having
all of the properties we would like it to have. A common example of what I have in
mind is when we say that something is good for an artifact, meaning that it will
enable the artifact to keep functioning and last for a long time. We prefer artifacts
that last for a long time, and that makes us think of artifacts rather as if they were
organisms, for it is part of the function of a living thing to last—that is, to keep itself
alive. But self-maintenance is not, or at least not obviously, part of the function of
an artifact. We even speak of an artifact in these contexts as having a “life.” Using
good gasoline, we say, will extend the life of your car. But does that make it better
at performing its function, which is serving as a means of transport? We do not
need to answer this question, because the whole issue arises simply because the
good of artifacts is just a projection of their goodness for us. But the things that are
good or bad for an organism really are good or bad for it, and not just for us. So an
1. Stones, unless regarded as missiles or pieces of pavement, cannot be well-functioning, nor can
topographical entities like mountains. For Aristotle, the stones are not a problem—in an
important sense, they are not really entities at all, but “mere heaps” of matter. For a defense see
my “Aristotle’s Function Argument.” I am not sure what to say about topographical entities.

organism really does have a final good in a much deeper sense than an artifact does.
Yet the objection may be pursued further. Do we even want to say that plants
have a final good? Many people believe that only beings who are conscious have a
final good. It at least seems true that things can be good or bad for conscious
animals in a deeper sense than they can be for a plant. And it seems extremely
plausible to suppose that a conscious being’s final good has something to do with
the state of her consciousness. For such a being, as I said earlier, in my discussion
of hedonism, we seem to require that her good be something that she can or even
does experience as a good. This gives rise to a question. Does the presence of
consciousness introduce a sense of “final good” and of “good for” which is simply
independent of the evaluative sense of good and the ideal of well-functioning that
that so naturally accompanies it? Or could some form of well-functioning still be
the good for conscious beings considered as such?
VIII. What Difference Does Consciousness Make?
This leads us to the question: what difference does consciousness make? There
seem to be three possible views we might take about the way in which the presence
of consciousness in a sentient being might affect the character of his final good.
One view is that consciousness introduces a new sense of “final good” that has
nothing intrinsic to do with a creature’s well-functioning at all. The hedonist’s
conviction that the good just must be pleasure is grounded in this way of thinking.
According to hedonists, when we talk about the good in the sense that is relevant
to ethics, the good that utilitarians think we ought to promote, we are not talking
about well-functioning at all, but about a distinct kind of final goodness made
possible by the existence of consciousness. Of course, well-functioning may, as it
happens, tend to the agreeable state of one’s consciousness, but that is not to say
that well-functioning itself is intrinsically connected to the final good.
Some of the familiar protests against Aristotle’s claim that we find our good in
the practice of moral virtue spring from the idea that the good has this ineluctably
subjective element. Imagine a gentle and generous human being who, in some
emergency, sacrifices his life for the sake of others at an early age. He is surely a
good person, and in one sense his life was a good one, but we do not feel easy saying
that he has thus attained his own good or the good for himself. His life is not
24
The Origin of the Good and Our Animal Nature / Christine M. Korsgaard
enviable or choiceworthy, although given the circumstances he did well to choose
as he did. At a notorious moment in the Nicomachean Ethics, Aristotle claims that
someone who sacrifices his life in battle “is getting a great good for himself” because
he prefers “a twelvemonth of noble life to many years of humdrum
existence”(Aristotle, NE, IX.8 1169a 25-30). Aristotle is trying to establish that a
morally virtuous act is always good from the agent’s own point of view, but the
claim seems absurd, not least because there is no reason to suppose a virtuous
person who fails to sacrifice himself will then have a humdrum existence. While the
virtuous choice may indeed always be better than the alternative —for a virtuous
soldier, desertion is not an attractive option—it does not seem to follow that you
always attain your own good by making a virtuous choice. Although this is not the
time to go into it, I do not think Aristotle really needs to draw this conclusion in
order support his own theory anyway, both because the good is supposed to be wellfunctioning in circumstances conducive to well-functioning, and because the wellfunctioning of a human being includes more than moral virtue. That is a longer
story. But the general point is that simply identifying the summum bonum with a
life that is good only in the sense that we would approve of it morally does not
satisfy the intuition that the good for a person must be something that that person
experiences or can experiences as a good, as something welcome from his own
point of view. And that leads people to think that the good must be some
experiential thing like pleasure.
But if even if we agree that the good for a person must be something welcome
from his own point of view, we may still wish to join the many philosophers in the
tradition who have resisted the hedonist idea that the good just is a certain state of
consciousness. The arguments here are familiar. It would be bad, we think, to
spend your life hooked up to a so-called experience machine—one that delivers a
steady stream of pleasant sensations and imaginary pleasant experiences directly
into your brain—and so to live in a dream.1 It would be bad, we think, to be hated
by the people whom you imagine love you and despised by the people whom you
imagine admire you. It would be bad to imagine that you are doing a great deal of
good by actions that are actually creating havoc, or to spend your life carrying out
some arduous project destined to collapse like a house of cards shortly after your
1. The problem of the experience machine was introduced by Robert Nozick in Anarchy, State, and
Utopia, (2013), pp. 42-44.

25
death. These things are bad even if you are fated never to be cured of your delusions
or to know of your failure. For, many philosophers would argue, it is not the case
that it is bad to be aware that you are hated, or despised, or a failure, or a walking
catastrophe to those around you, simply because the consciousness of these things
is painful; rather, these conditions are objectively bad, and that is why the
consciousness of them is painful: because it is the consciousness of something bad.
These reflections give rise to another view we might take of the difference that
consciousness makes. Perhaps consciousness does not make any difference to what
constitutes your final good: perhaps it simply enables you to be aware of whether
you have achieved that good or not.
But that does not seem right either. The arguments I just mentioned work by
driving a wedge between an agreeable consciousness and a bad reality; but we can
also construct arguments that drive a wedge between a disagreeable consciousness
and a good reality. Perhaps you are loved by people whom you believe despise you,
and perhaps your own efforts, that seem so fruitless to you, are actually setting
humanity on its collective feet. Are we to say of someone who suffers from these
negative delusions that he had a good life (in the final, rather than the moral sense)
but failed to know it? That does not seem right. This consideration brings us back
to the idea that the final goodness of a life depends on whether it is perceived or
experienced as a good life after all.
I do not think we should resolve this conundrum by picking one side or the
other: that is, either by deciding that the good just is agreeable consciousness after
all or by deciding that it is something wholly objective of which consciousness
merely makes us aware. Rather, I think we should conclude that the concept of
goodness, in the final sense of goodness, has a kind of reflexivity about it: nothing
can be a final good if it cannot be perceived as a final good, and indeed the final
good is, as it were, made complete by our perception of it. Someone who is unaware
of the goodness of his life therefore actually has a less good life. Or rather, we might
say, the concept of being an entity that has a final good is reflexive in this way.
Nothing can have a final good that cannot be aware of its final good as such. In this
respect, the concept of having a final good parallels the concept of having a personal
identity: for as many philosophers have noted, nothing can have a personal identity
that is at not least potentially aware of itself as having a personal identity. Having
26
The Origin of the Good and Our Animal Nature / Christine M. Korsgaard
a self-conception is not merely having a conception of a self that exists
independently of that conception. And in the same way, having a consciousness of
the good is not merely having a consciousness of a good that exists independently
of that consciousness. I think we should adopt this third view of the relationship
between consciousness and the final good. If we are tempted to say that only
conscious beings have a final good, it is because having a final good, like having a
personal identity, is a reflexive property that only a conscious being can have.
IX. Animals and the Good
Personal identity and the goodness of your life depend on consciousness. These
things can only be had by beings who can be aware that they have them. But this is
certainly not to say that either the goodness of your life or the character of your
identity are whatever you take them to be. They are the awareness of something,
even if it is not something wholly independent of that awareness itself. According
to Aristotle’s theory, what a being that has a final good is aware of it is own wellfunctioning, of its goodness in the extended-evaluative sense. But this suggests a
very tight connection between the nature of an animal as Aristotle understands it,
and the idea of a being who has a final good. For an animal is not merely aware of
her own well-functioning: her awareness of her own well-functioning is itself an
evaluative awareness. And that is essential to the way she functions. She functions
by standing in an evaluative relation to her own well-functioning. She functions by
experiencing her good as a good.
Here’s what I mean: the distinctive form of life that characterizes an animal
involves the maintenance of that very form of life by means of a relationship that
obtains between the animal and her own functioning: the animal monitors her own
functioning and has positive evaluative attitudes towards the things that promote
her functioning and negative ones towards the things that will inhibit it. These
evaluative attitudes motivate her to act in ways that promote her good. To put it
more simply and intuitively, healthy, well-functioning animals like to eat when they
are hungry, are eager to mate, fear their enemies, work assiduously to keep
themselves clean and healthy, and so on. (Do not say “well, of course they do”.
Allow yourself to be struck by the fact that there are entities, things, that attend in
this way to the goodness of their own condition). What these phenomena show is
that the function of an animal is to take care of itself —and nature made that
The Journal of Ethical Reflections, Summer, 2020, 1 (2)
27
possible by designing the animal to care about itself—by which I mean, to enjoy
and suffer from her own extended-evaluative condition. On Aristotle’s conception,
that is not just a fact about animals: that is what an animal essentially is, something
that functions by caring about herself, and how she is doing. Animals have a final
good because it is their nature to have evaluative attitudes about their own
extended-evaluative condition. And that is what a final good is: a final good is
something that constitutes or contributes to the good condition of something that
can experience its own condition as a good. That, I want to say, is the Aristotelian
theory of the nature of the final good. To put it more carefully, Aristotle’s theory of
the nature of the final good is that a final good is something that constitutes or
contributes to the good condition of something that stands in an evaluative
relationship to its own condition. Since an animal is essentially something that
stands in an evaluative relationship to its own condition, to say that an animal has
a final good is a kind of tautology. The two concepts—the concept of a being with a
final good, and the concept of an animal—are pretty much co-extensive.
X. The Puzzle Resolved
Now I return to my puzzle. What are we evaluating, when we say that something is
good, in the final sense, and in what respect are we evaluating it? We are evaluating
the condition of a being who stands in an evaluative relationship to his or her own
condition. We might say that the judgment that something is good for someone
(some person or animal) in the final sense is essentially empathetic, because when
we do it we must be viewing the person’s or animal’s condition the way the person
(or animal) herself must view it, namely: evaluatively.
And what gives this evaluation content—the reason why this formula is not
empty—is that we are using the extended-evaluative notion of the good to appraise
the being’s condition. Furthermore, this knowledge of what we are doing when we
use the concept of the good may make it possible for us to determine what the
content of the good for that being will be, without recourse to mysterious intuitions.
We just have to learn how the being functions.
To achieve the good in the final sense, then, is to be aware of oneself as being
in a good condition in the evaluative sense—to be aware of oneself as wellfunctioning, as the kind of thing that one is. All of this is just an overly analytic way
28
The Origin of the Good and Our Animal Nature / Christine M. Korsgaard
of saying that the final good for an animal is to be conscious of her own healthy life,
or more correctly to be conscious of herself as healthily alive. In the human case,
that includes functioning well in the life of rational choice, with all that that entails.
If Aristotle and Kant are right, being well-functioning in the life of rational choice
entails being morally well-functioning, so that is part of our good. According to this
view, people who express their sense of being in a finally good condition by saying
that they really feel alive are saying something literal. They feel their life, and they
feel it as a good to them: and that is something that it is in the nature of an animal
in a good condition to do.
XI. Conclusion
The view I have just described is essentially Aristotle’s, with a modification in favor
of an emphasis on consciousness. This modification seems to me to be necessary to
capture the essential subjectivity of the idea of the final good, the reflexive element
in the concept of a being that has a final good. I think that the theory so modified
captures the element of truth in hedonism, without falling into the characteristic
error of utilitarianism. On this theory, everything that is a good is a good to or for
some sentient being. The final good is essentially relational, not intrinsic, because
it is derived from the evaluative relation in which an animal, by her very nature,
stands to herself. Because it is essentially relational, it cannot be added across the
boundaries between persons, or other animals.
Another advantage of this theory, when combined with the Kantian theory of
value, is that it enables us to explain the existence of value in a naturalistic way. On
the intrinsic value theory, various objects, activities, and experiences simply have
intrinsic value. There is no explanation of why that should be so: it is just a fact.
The value of the objects and activities comes first, and there are valuing beings—
beings who have a final good—because there are beings who are equipped to get in
touch with those values. On the Aristotelian-Kantian theory I propose, the order of
dependence between valuing and values goes the other way. Values exist because
there are valuing beings, beings who have evaluative attitudes towards their own
condition, beings for whom things can therefore be good or bad. It is because there
are such beings—animals—that there is such a thing as the final good.
