Abstract This paper responds to the four critiques of
my book Experiments in Ethics published in this
issue. The main theme I take up is how we should
understand the relation between psychology and
philosophy. Young and Saxe believe that bottom
line evaluative judgments dont depend on facts. I
argue for a different view, according to which our
evaluative and non-evaluative judgments must cohere
in a way that makes it rational, sometimes, to abandon
even what looks like a basic evaluative judgment
because we have changed our minds about the facts.This leads me to qualify Tiberiuss claim that our
moral judgments always derive, in part, from funda-
mental evaluative justificatory stopping points,
arguing that even these can themselves be adjusted
in the light of scientific understanding. Weinberg and
Wang object to my use of Kants distinction between
the perspective of the senses and the perspective of
the understanding, because they identify it with a
distinction between scientific and philosophical
worlds. I argue that a distinction of perspectives isnt
a distinction between worlds and that, in any case, thedistinction is not between science and ethics. Finally,
in responding to Macherys objections to a couple of
my proposals, I return to the suggestion that a
coherentist epistemology is required to deal with the
relations between science and ethics.

Let me begin by saying how gratifying it is that
Experiments in Ethics has helped elicit four such
interesting responses. One of my main aims in writing
the book was precisely to draw attention to the rangeand interest of the work going on at the interface of
moral philosophy and the social sciences. I think
these papers, with their diversity of issues, disciplin-
ary backgrounds and methods, reflect the vigor of the
intellectual life of what the moral sciences (as I
suggested we might call them once more) today. So
let me say something about some of my agreements
and disagreements with each paper before making a
few concluding remarks at the end. I begin with
Young and Saxes paper. But in the course of
discussing it, as you will see, I will come acrossissues that reappear in my discussion of the others.

ness. Among the conclusions they draw from their
own experimental work is this: when someone acts in
the belief they will harm someone else but, in fact,
causes no harm, they are regarded as more blame-
worthy than someone who acts in the belief that they
will not harm someone but, in fact, causes harm. This
fits with an old idea in moral philosophyoneexpressed, perhaps, in the first sentence of Kants
Groundwork of the Metaphysic of Moralswhere he
says that a good will is the only unqualifiedly good
thing in the world. Kant puts the point emphatically in
a famous passage on the next page:
A good will is not good because of what it
effects or accomplishes, Even if, by a special
disfavor of fortune or by the niggardly provision
of a step motherly nature, this will should
wholly lack the capacity to carry out its purpose
then, like a jewel, it would still shine byitself, as something that has its full worth in
itself [1].
Many people have pointed out that, though a good
will is, no doubt, a good thing, what happens in the
world matters, too. It is bad when what I did leads to
harm to another whether or not Iam bad for having
acted in the way that had this bad consequence. And
our actual responses to situations that involve what
Bernard Williams dubbed moral luck suggest that
we sometimes evaluate people in ways that depend onwhether or not they achieved their aims: we appear to
treat murder as more blameworthy than attempted
murder, even when the difference between the two is
the result of a gust of wind that blows an arrow off
target [2]. Still, Saxe and Young are surely right that
we evaluate people, in large measure, on the basis of
the mental states with which and on which they act.
I am not quite sure how I managed to give them
the impression that I wanted to deny this. You might
think, after reading their paper, that I dont discuss the
relevance of internal states other than character tomoral evaluation. But the discussion of intention in
the section on Folk Psychology Unplugged in
chapter 3 is exactly about that. Its true that I dont
say much about the question how thoughts about the
beliefs and desires of agents figure in moral evalua-
tion. I hadnt thought there was work in experimental
psychology that challenged standard philosophical
views on this question. If Id been aware of their
own very interesting work on this topic, I might
indeed have taken this issue up: except that, as they
themselves argue, nothing in their work undermines
standard moral common sense. Their work is consis-
tent with thoughts that are routine both in informal
moral discussion and in moral philosophy: that in
deciding how culpable someone is we need to
consider both what they thought they were doingand what they were aiming to do; that it is, other
things being equal, worse to act with malice towards
others than to act without malice; and so on.
I take their own work to show many important
things: first, that, in normal adults, the right temporo-
parietal junction (RTPJ) is active when we are
analyzing of the role of states such as belief, desire
and intention in the actions of others; second, that
normal adults do indeed make moral evaluations of
agents blameworthiness in ways that give great weight
to various aspects of what the agent believed, intendedand desired; and third, that one feature of Asperger
Syndrome is an imperfect development of this capac-
ity, which appears quite late in normal development.
The second of these conclusions is one that will be
welcome to many moral philosophers, because it
shows that people are doing something like what
moral philosophy suggests they should do. Most
philosophers who have thought about holding people
responsible for their acts recently think that in
deciding what agents can be held responsible for we
need to bear in mind their beliefs about the situationin which they were acting, the aims with which they
acted, as well as (something that Young and Saxe
dont discuss in their paper) what they ought to have
known or aimed at. That the normal functioning of
the RTPJa part of the brain that appears to be used
for analyzing states of intention, belief and desireis
crucial to standard attributions of responsibility is, as
they point out, quite consistent, as a result, with what
most philosophers already believe.
One thing in the way they describe their work seems
to me, from a philosophers point of view, a littlemisleading. They move too easily, I think, between talk
of belief and desire and talk of what is intentional and
accidental, without explicitly invoking the idea of
intention, and without noting that the vocabulary we
use in these areas is notoriously slippery.1 The word
intentionoccurs only once in their paper, in the phrase
1 See, for example, J. L. Austin [3].

mental states (e.g. intention).2 Perhaps the word
desireis vague enough in ordinary usage to cover not
just what we want to do but also what we intend to do,
but these seem to me to be different questions; and
different in ways that are morally important.
Consider the scenario with Bill, Frank and Susan,
they describe from Woolfolk, Doris and Darley:
In one variation of the story, their plane is
hijacked by a gang of ruthless kidnappers who
surround the passengers with machine guns,
and order Bill to shoot Frank in the head;
otherwise, they will shoot Bill, Frank, and the
other passengers. Bill recognizes the opportuni-
ty to kill his wifes lover and get away with it.
He wants to kill Frank and does so. In another
variation: Bill forgives Frank and Susan and is
horrified when the situation arises but complies
with the kidnappersdemand to kill Frank.
In this case it seems to me natural to say that the
issue is really desire and not intention: in both
scenarios Bill acts with the intention to kill Frank
and, what is not exactly the same thing, he kills Frank
intentionallybut in the second he does so, as one
might say, against his desires. So it is the presence of
the wish that he didnt have to kill Frank, even though
he doesnt act on it, that provides some degree of
excuse for Bills behavior.
In their own scenario, however, in which Grace
accidentally poisons a friend because she quite
reasonably assumes that a white substance in a
container labeled sugar is sugar (and not the toxic
substance it actually is) what matters is that she had
no intention of harming her friend, not just that she
didnt want to. Even if she had desired to harm her
friendand even though this would be a bad desire to
haveit wouldnt have made the death any more
blameworthy. Grace would be a bad person for having
this desire, but she wouldnt be any more culpable for
the death.3 So we need to keep clear the distinction
between whether we think the agent is blameworthy
and whether she has desires she shouldnt have,
whatever we think of the consequences of her act.
Here is a place where the hope, which I expressed
inExperiments in Ethics,that there might be a fruitful
passage of ideas between philosophy and psychology
might be realized, if psychologists took up experi-mental work that explored scenarios which distin-
guished between the roles of intention and desire in
inculpation and exculpation more explicitly.
When it comes to the view that Young and Saxe
express about the relations between science and
philosophy in this area, Im afraid I think things are
not as simple as they claim. Their picture is this. There
are bottom line evaluative judgments that dont
depend on factsand so can neither be supported nor
undermined by science. This is a picture that suggests a
broadly Humean moral epistemology: we have basicevaluative commitments, ends which derive from the
will, and facts are relevant because they are relevant to
identifying means to those ends. On their view there
are, so to speak, axioms, moral foundations on which
we build. I am doubtful of this picture.
Consider two examples they offer ofbottom-line
moral thoughts:
M: mental states matter to moral evaluations,
IN: incest is wrong.
The place of claims like these in our moralthinking strikes me as better understood on a
coherentist than on a foundationalist view. Precisely
because our moral thought is not a system with
axioms that we cannot doubt, but more like a network
of claims that we seek to bring into coherence,
scientific evidence could, I think, be relevant to each
of these claims.
Take M. One possible view in cognitive psychology
is a form of eliminativism about belief, intention and
desire: a theory on which there are no such states.4 This
philosophical view is motivated by a great deal ofscientific evidence. If it were true, the mental states
that are supposed to matter to moral evaluations would
notor, if you like, would not reallyexist. So M
does have factual presuppositions; or, more precisely,
our ability to use M in our moral lives depends on
certain eliminativist theories being false. I dont know
4 See, e.g., P. M. Churchland [5].
3Of course, youd actually have to do the experiments to find
out whether most people carved up the territory as I have (and
as, I suspect, many other philosophers naturally would). Then
youd have to decide who was right.
2 The distance between the way we use the word intentional-
ly and our concept of intention is one theme of the literature
that grows out of Joshua Knobes paper [4], which is a
significant landmark in the recent turn to experimental
philosophy I discuss in the book.

how I would react if I thought eliminativism was right:
but Im not sure that I would conclude that I should
give up moral evaluation.
IN is also rationally sensitive to empirical fact.
While I cannot produce a particularly plausible
hypothetical here, there are surely rather unlikely
scientific theories whose truth would turn around theclaim that incest was always wrong. Suppose, for
example, it turned out that there were certain mental
disorders that could be eradicated in some people, if
they engaged in incest. (Not just if they thought they
had engaged in incest; suppose the genetic relatedness
of the parties is part of the causal mechanism.) John
Haidts arguments to dumbfound those who think
incest is wrong tend to involve showing them that
certain arguments against incest have false premises.
So he focused on undermining arguments against
incest. The main argument in favor of incest heinvited people to consider was, in essence, that people
should be free to do together what they both want to
do, provided it harms no one else. Since we are used
to the idea that sexual morality is not just about
whether you harm others, many people find this
argument unconvincing.
But offered the consideration that someone who
was severely mental ill could be cured by sex with a
willing sibling (and in no other way we know of),
someone might reasonably come to the view thatin
these circumstancesincest was permissible. Natu-rally, they could hold on to the view that incest was
bad in itself but permissible if it had enough positive
countervailing consequences. Deciding whether a
scientific claim had led them to modify their bottom
line moral judgment in this sort of case would require
us to settle on an exact formulation of the judgment.
But notice that I am not taking IN to mean that every
act of incest is impermissible: that claim would
simply be refuted by the existence of cases where
incest was the best option.
Defenders of IN as a bottom-line judgment mightconstrue it in a variety of ways. Here is one: the fact that
an act is an act of incest provides a moral reason not to
engage in it. On this view, our response to the sorts of
hypotheses I just mentioned shows only that such a (so-
called)pro tanto reason to avoid acts of incest can be
over-ridden by other features of the act. We can still
believe that being-an-act-of incest is a wrong-making
feature, even when other features either undermine or
out-weigh the force of this feature. My claim,
however, is that sufficient scientific evidence about
incest (including, perhaps, evidence about how our
judgment that it ispro tantowrong was formed) could
lead us reasonably to abandon the pro tanto judgment
altogether. Indeed, I see no reason to think that there is
any formulation of IN that it is plausible to ascribe to
actual moral thinkers, which couldnt be affected inthis sort of way by scientific evidence of some
imaginable (if highly unlikely) sort.5
Part of the reason I believe this is that I grew up in
two places with different notions of incest. In the
Akan culture of Asante, where my father was born,
sex with the children of your fathers sister, far from
being incestuous, is regarded as a sort of ideal. I grew
up calling my fathers sisters daughter my wife.
Sex with your mothers sisters child is the worst kind
of incest, on the other hand; as bad as sex with your
own uterine sibling. Since these are just two kinds offirst-cousin, so far as people in England, where my
mother was from, are concerned, my English relatives
would have found this distinction quite baffling.
(Perhaps you do, too.)
One way to make sense of this way of thinking is
to understand the picture of how a human being is
made that underlies it.6 People are supposed to be
composed of three significant elements. A body,
which is made out of your mothers blood, and two
kinds of spirit-like elements: thesunsumand thekra.7
Yoursunsumcomes from your father and accounts for
6 For further philosophical exploration of Akan conceptions see

5 Neil Levy, in comments on the first draft of this paper, urged
me to make my views here clearer. I had the good fortune to
hear a talk by Arudra Burra, a graduate student here at
Princeton, while I was thinking about how to do so, in which
he gave a very careful treatment of similar issues about whether
lying is pro tanto wrong. He argues it isnt. (I say more about
pro tanto reasons in the section on Seeing Reason in Chapter
3 of Experiments in Ethics.) Some might respond that in
picking the incest example I made the case too easy for myself,
because they think that the bottom-line judgments are moregeneral (causing pain is wrong) or more particular (doing this
here and now is wrong). I realize that one will need different
arguments to persuade people of different philosophical
positions of the need to make factual and normative claims
cohere.
7 I say blood because the word thats used is the same as the
word for the red stuff that runs in your veins. Obviously,
though, this is a conception of blood that will differ from the
one held by most readers of this article.

many aspects of your personality. It is your sunsum
whose experiences produce dreams, because it can
leave your body when you are asleep. (Yourkra, on the
other hand, never leaves you until you die: it is a sort
of life force.) On this theory, as you will quickly see, I
and my mothers sisters children share the same
blood. My fathers sisters children share bloodwith him and with their mother, but not with me. So
incest here is sex with a close blood-relative.
The pattern of incest-avoidance that I described
coheres in an obvious way with this picture of the
nature of the human being. Absent this picture, I think
it is quite natural to feel less drawn to the pattern of
incest-avoidance. It would be reasonable to deny that
this picture of the human being was scientific: but
science could persuade you that it was incorrect.8 So
here is a case where, so it seems to me, anyone can
understand why learning a piece of science might leadyou to modify a commitment like IN (construed as a
pro tanto judgment).
So I continue to think that we have to take the sorts
of matters that science explores into account, even
when we are thinking about very central moral beliefs.
Let me say, finally, that there are two places where
Young and Saxe seem to misunderstand something I
wrote. First, they say, Appiah never acknowledges
that there may be a moral fact of the matter. Thats
not quite true. What I did was explicitly declare that I
wasnt going to take sides on the issue of moralrealism in the book. Heres what I wrote: I suspect
that a preoccupation with whether moral sentences are
fact-stating or truth-apt is, in some measure, an
artifact of the exaggerated authority that the philoso-
phy of languagemy own sub-disciplinary alma
materhas enjoyed for much of the postwar era.
And I shall endeavor to treat without prejudice realists
and quasi-realists and anti-realists [7]. My view is
that whether you say youre a realist or not, you can
accommodate the needed distinction between what is
morally true and what people think is morally true;that is you can construct a notion of moral error with
or without metaphysical realism.
The second, and perhaps more consequential,
misunderstanding, is that, pace Young and Saxe, I
do not favor virtue ethics. I did defend one
consequence of virtue ethics, which is the view that
it matters not just what we do but who we are. My
discussion of character, however, was meant to
suggest that the notion of who we are implicit inmuch virtue ethics was misguided. Who we are is not
a matter of character, I argued, as conceived of either
in common sense of most virtue ethics. The most
important moral significance of the truth of situation-
ism in social psychology, I think, is that we should
focus on shaping peoples circumstances in such a
way as not to place them in the sorts of situations
where humans tend to behave badly. One obvious
example of a relevant piece of social psychology is
Zimbardos experimental work simulating prison
conditions: his work has obvious implications forthe social organization of real prisons (lessons, which,
as he has pointed it out, were entirely ignored at Abu
Ghraib, to the everlasting shame of our country) [8].
Tiberius on the Autonomy of Ethics
I agree very much with very much of what Valerie
Tiberius says, including her claim that my articulation
of what I meant by the autonomy of ethics could have
been clearer. And I am attracted to her account ofwhat is true and false in the claim that ethics is
autonomous of the sciences. I am especially attracted
to her clear articulation of four things that ethicists
can usefully do, each of which can be better done if
we keep an eye on the best scientific understanding:
i) apply anthropology, psychology, and other social
sciences to ethical problems.
ii) modify traditional conceptions of the good life
(or traditional theories of morality) in light of
new empirical findings.
iii) draw out the implications of the commitments
we already have.
iv) advocate certain commitments, portraying them
in a way that makes them attractive or compelling
to those who do not recognize them as their own.
But let me suggest some complications to a view
that I think, as I say, is broadly correct.
The first complication I have in mindand it is
one that is not inconsistent with anything Tiberius
8 How reasonable it is to regard the view as unlike a scientific
one is actually a complex issue: see K. Anthony Appiah

West by Robin Horton Times Literary Supplement (July 2

actually saysis that we need to be clear about the
role of what she calls fundamental justificatory
stopping points. Tiberius says (echoing an observa-
tion of Young and Saxes Ive already discussed):
when we reflective creatures ask for a justification,
what we need is an answer that already counts as a
reason for us (and again, not necessarily an ethicalreason). A justificatory stopping point must therefore
be something we are already committed to that is not
in question. So, there is a sense in which ethics retains
its autonomy.But the force of this argument depends
on a proper understanding of what it means to be
committed already. At any time, my justificatory
stopping points will, indeed, be fixed. As my
scientific understanding of what human beings and
our world are like grows, however, those stopping
points may shift. It is indeed true, thenat each
momentthat, as Tiberius says, [j]ustification stopsnot at a body of facts, but at a pattern of normative
commitments that cant be improved uponat that
moment. But I believe that one of the things that can
improve a pattern of normative commitments is its
fitting better with a total picture, informed by the
sciences, of what we human beings are like.
Whatever this fitting better means, it is not a
matter of mere logical consistency. Consistency can
seem demanding enough at times, but it will not be
enough to guarantee the right sort of coherence.
(Consider the example of Asante attitudes to incest Igave earlier: theres nothing logically inconsistent in
continuing to believe the traditional pattern of incest-
avoidance is right while giving up the belief that your
body comes from your mothers blood.) So the
form of coherentism that I want to gesture at is one in
which our normative commitments and our picture of
the world are being adjusted to one another as time
goes on.
Now we cannot entertain our total picture in a
single reflective moment and much of the time our
thinking will be very local within the vast web of ourideas. That is one perfectly good reason for organiz-
ing our inquiries into fields, so that within, say,
psychology, the implications for our moral lives of
our psychological understanding is not at the center of
attention; just as m uch of the tim e in m or al
philosophy we wont need to focus on the detailed
psychological presuppositions of our arguments. I
accept the need for a division of intellectual labor,
which has been a crucial part of the great epistemic
leaps of the last few centuries. But I want to insist that
even though we need to divide up these tasks, they
are all, in the end, connected.
This is evident in the fact that science, especially
social science, will naturally use language with
embedded normative commitments. Political scien-
tists seek evidence about whether democracies aremore or less likely to fight wars than authoritarian
states. Anthropologists discuss conceptions of incest
in relation to kinship structures. Psychologists explore
the question whether psychopaths experience guilt.
The concepts of democracy, incest and guilt are moral
concepts. Their presence in a thought engages moral
commitments.
Many people appear to believe that when these
concepts are invoked in the sciences, the scientific
content of the claims can be identified by replacing
the normative terms with some non-normative termson which they supervene. This thought is supported
by some forms of metaphysical naturalism, which see
normative properties as constructed out of non-
normative properties by the addition, so to speak, of a
normative commitment. (In the simplest sort of
model, incest is composed of the non-moral
concept of sexual relations with near kin and a
con-attitude.)
Even supposing this is the right metaphysical
picture, however, that is no reason to think that our
normative commitments play no epistemological rolein allowing us to identify the extension of normative
predicates. (In the simplest model, the extension of
As near kin in the concept of incest will depend in
part on whether we find ourselves with a con-attitude,
all things considered, to sexual relations between A
and some person.) To grasp and use the concept of
kindness it is not sufficient, of course, to be able to
specify its extension in the actual world, since grasp
of the concept entails a capacity to think about
possible acts of kindness as well. But I see no reason
to think that our capacity simply to identify actualacts of kindness is independent of our grasp of what is
normatively appropriate. If we need to recognize
moral norms in order to grasp moral concepts, then
understanding these scientific claims presupposes a
grasp of moral norms.
The relations between our normative thought and
the sciences thus go both ways. Without moral
understandinggrasp of moral conceptswe cannot
understand certain scientific claims, just as, without

the sorts of knowledge produced by the sciences, we
cannot act upon our moral ideas.
Weinberg and Wang on Naturalism
Jonathan Weinberg and Ellie Wang do a good job ofresisting my failure to endorse a more enthusiastically
naturalistic perspective. So let me declare myself
happy to accept their notion of a naturalism of
plenitude: stocking our ontological pantry with
strange and wondrous ingredients never dreamt of in
armchair philosophy. They do a good job, too, in
their discussion of character, of showing how some
psychological literature that I didnt discuss could
allow one to fill out the picture of the human person
in ways that would allow us to keep more of the
insights of virtue ethics than I allowed. The generaloutlines here I accept, even if I might want to disagree
with a few details. This is exactly the sort of fruitful
engagement between moral thought and psychology
that I believe is most valuable.
But I am unconvinced by their unwillingness to
accept my use of a distinction between perspectives, a
distinction that I borrowed, with modifications, from
Kant. The major modification is that I wanted to stick
with a distinction of perspectives and not to go on to a
distinction between worlds. Weingberg and Wang
want to deny me this modification. It is a distinc-tion, they write, etymologically at least, between
two separate worlds, and it is not made clear in
Appiahs book just how, once this distinction is in
place, we are to recover that continuity between
sciences world and philosophys.
I dont think I grasp why the metaphor of a stance
leads to a distinction between worlds. The etymolog-
ical point applies to Kants choice of terminology: the
Sinnenwelt, the Verstandeswelt. That is true. But I
consistently stuck to talk of stances and perspectives
in order to underline my defection from this feature ofKants thought. A stance (etymologically) is a way of
standing; a perspective what you see from one place
you might stand. Both metaphors are meant to suggest
that there is one world being looked at in different
ways.
Furthermore, the perspectives in question are not a
philosophical perspective and a scientific one, but one
in which we look at the world as agents and one in
which we look at it as objects. Kant invoked this
difference of perspectives to try to explain how one
could still approach the world as an agent if one
believed (as he did) that ones body was an object
embedded in a system governed by causal laws. His
insight, I believe, was this: you cant approach a
decision with the thought, Im a causal object so
what happens next is fixed by causal laws. What tosay here is, I think, one of the hardest questions in
metaphysics. But I dont think that you can eliminate
the gap between these perspectives by observing that
there is only one world. I think that Weinberg and
Wang agree with me about this, because they say:
Perhaps we can find a way of viewing the world as
possessing both explanations and justifications all at
once, in one-but-not-entirely-unified perspective.
They are recognizing here exactly the impossibility
of pulling Kants two perspectives into one.
I think Kant was right, too, to link the differencebetween the perspective we adopt as agents and a
purely naturalistic perspective to a distinction be-
tween reasons and causes (or justifications and
explanations, as Weingberg and Wang put it). Facing
the world as an agent, I find reasons to do and think
and feel things imposed upon me, so to speak, in
my experience. Naturalism can mean many differ-
ent things. But if it entails a picture of the world in
which there are no reasons, then I do not see how you
can be a naturalist. If, on the other hand, like
Weinberg and Wang (and me) you accept that thereare both explanations and justifications, you have to
accept, with Tiberius (and me), that there are
justificatory stopping points that are not themselves
given by the causal structure of the world.
The integration of science and ethics we are all
defending is focused, more specifically, on bringing
together what I called the moral sciences with
philosophical reflection on how we make a success
of our lives. But there are other sciences. And the
physical sciences are hard to integrate with the moral
sciences (let alone with ethics) for many reasons. Oneis that the best contemporary physics arguably does
without a notion of causation altogether. Another is
that we have no notion at all how to integrate, say,
psychology with physics, because their vocabularies
are so remote from one another.
You might observe that the integration of psychol-
ogy with economics is not in terribly good shape
either. The micro-foundations of economics that were
worked out through the use of game theory and
More Experiments in Ethics 239
8/13/2019 More Experiments in Ethics
8/11
decision theory relied on a picture of human psychol-
ogy that was thin to the point of evanescence. But we
have some new ideas today about how to bring
psychology and economics closer together, as behav-
ioral economists enrich the psychological micro-
foundations of economics. This is not a reduction of
economics to psychology, as reduction was conceivedby the received view of scientific theory and
explanation we inherited from positivism; but it is
consistent with the wider aim of the unification of our
various pictures of the world.
In this sense, though, physics, on the one hand, and
psychology and the moral sciences on the other,
remain totally unintegrated. For while neuroscience
uses tools, like fMR imaging, that depend on recent
physics, nothing of significance for psychology
depends on details of physical theory.
I bring this up to underline a point I made earlier:much modern intellectual progress is the result of an
intellectual division of labor. Psychology proceeds
better without worrying about exactly how the latest
models of cognition, say, fit with the latest under-
standing of fundamental physics. Even enthusiasts for
integration like Weinberg and Wang must agree that,
at any moment in the history of human understanding,
there will be limits to where integration can profitably
be pursued. In finding those limits it will not be
helpful to appeal to the idea of naturalism or to the
idea that there is only world.
Macherys Naturalism of Deprivation
Weinberg and Wang accuse me of working primarily
with a naturalism of deprivation: the naturalists job
is to pop the metaphysicians balloon, and keep her feet
planted back on (empirically) solid grounds. I am
going to try to work hard to eliminate this habit of
mind. But if they are looking for others to convert, I
think they need look no further than Edouard Machery.Machery assembles a good deal of psychological
evidence against two projects that I endorsed in my
book, aiming to pop a couple of my ethical balloons.
The first of those balloons is my view that it
matters, as I put it, who we are. As I mentioned in
discussing Young and Saxe, I argued in the book that
we should hold onto the idea from virtue ethics that it
matters what kinds of people we are. Machery
assembles a compelling case that there are reasons
to doubt that human beings have enough psycholog-
ical unity for it to make sense to speak of kinds of
person. And, since ought implies can, if we cant be
people of those kinds, it must be wrong to claim that
we ought to aim to be people of certain kinds. (He is
also doubtful that the properties that people do carry
across contexts are the sorts of properties we canaffect. Once more, my proposal is threatened by the
contraposition of ought implies can.)
My main response to Macherys argument against
caring about what kind of people we are is to concede
that he is completely right that the project requires a
laborious study of human behavior; and then insist
that I simply dont think that the evidence from that
study so far supports his view that the causes of
human behavior will turn out to be largely disuni-
fied. But I think he also misunderstands (like Young
and Saxe) the extent of my attraction to virtue ethics.(Clearly, then, the fault here is mine not theirs.) So let
me be clear finally: I do not think that caring about
who you are is the same as caring about character as
conceived in most virtue ethics.
What does caring about who you are entail then?
First, I believe, a concern for certain narrative features
of ones life. When I started on the project of writing
Experiments in Ethics I was going to make a plea for
even more cross-disciplinarity than the engagement
between ethics and the moral sciences. I had intended
to write as well about how both literature and literarystudies illuminate ethical questions. Had I completed
that larger project, I would have said more about this
question, and it would take a good deal more space
than I have here to do this issue any sort of justice. So
let me just exemplify what I have in mind.
At the end of chapter 2, I spoke making it easier
both to avoid doing what murderers do, and to avoid
beingwhat murderersare.I hope it is clear both that a
murderer is a kind of person and that being-a-murderer
is not in any obvious sense a matter of having a certain
character. If you intentionally kill someone neither inself-defense nor in warfare, your life is the life of a
murderer. That fact sits, I believe, in the negative
column in the accounting necessary to decide whether
or not your life has gone well. It matters, I think, beyond
the fact that you did something morally wrong. So, too,
the fact that you killed someone accidentally can also sit
in the negative column, even if you did so in a way that
was not morally culpable. That is because ethical
evaluation reflects moral luck as well as moral choices.

This is, no doubt, a controversial claim. Less
controversial, I think, will be the observation that caring
about who you are can involve exactly some of the
things that Machery admits we cando. So, for example,
he discusses the extent to which we can controlby
over-ridingsome of the automatic System 1 processes
stressed by those, like Bargh, who have drawn attentionto the automaticity of many of our responses. Having
conceded that we can at least sometimes regulate our
System 1 responses, Machery says:
the extent to which we can control them is
unclear. For instance, control seems very diffi-
cult when we are tired or when we have to
decide very quickly. In addition, because control
is effortful and might deplete our mental
resources, control might be often followed by
a lack of control.But committing herself to exercising control when
she can (when she isnt tired, in a hurry, or stressed by
earlier attempts at control) is exactly the sort of thing
that someone concerned with who she is might do. As
Machery rightly insists, you dont have to derive the
insight that it is hard to be virtuous from recent
experimental psychology. Machery continues:
Second, and more important, controlling the
automatic processes is one thing, changing them
is another one. It is unclear whether merelycontrolling the expression of some of the states
and dispositions that are meant to constitute
character and the kind of person we are (rather
than changing them) counts as changing the
kind of person we are
Here, I think, there are two things to say. One is
that we have good evidence that we can, at least
sometimes, modify these implicit attitudes. Cordelia
Fine has pointed out that work by Monteith et al
(among others) suggests that these processes are in
fact sensitive to reflective control in at least twoimportant ways: first, they may be the result of the
automatization of reflective judgments; and second,
they may be over-ridden with sufficient effort, when
avoiding error is a sufficiently salient aim which it
can be for distinctively moral reasons.9 We know, in
any case, that peoples automatic responses differ in
ways that are culturally variable. The race-based
implicit attitudes Machery mentions, for example,
differ in different sub-populations of the world for
reasons that no one believes are simply genetic. (For
one thing, conceptions of race differ in culturally-
shaped ways.) There is work in social psychology that
supports Gordon Allports Contact Hypothesis,which suggests that productive association across
racial lines of certain sorts leads to a reduction in
negative race-based attitudes.10 Suppose this is true of
implicit attitudes as well; then, you might well engage
in such productive association in part because you
didnt want to be the kind of person that had racially-
biased implicit attitudes.
But a second thing to say is that, if there are
dimensions of the person that you can do nothing
about, it doesnt follow that you cant take them to
be ethically important. I am irredeemably irascible incertain contexts. Theres nothing Im aware of I can
do about this, except try to avoid those contexts
when I see them coming. But this fact sits in the
negative column in my account. And the way my
recognition of this fact shows up is not in my
changing anythingI cantbut in my regret.
The other one of my claims Machery wants to
undermine (the other balloon he wants to pop) is a
proposal I made about moral intuition. I suggested we
could learn something about which of our moral
intuitions we should trust by studying the psycholog-ical processes that produce those intuitions. Though it
comes with a good deal of interesting psychological
detail, the heart of Macherys argument here is more
standardly philosophical: he thinks I have not shown
there is a non-circular way to do this.
The details of his objection here are not crucial,
because I want to concede this point. The gestures
towards a coherentist epistemology that I have made
several times already naturally raiseas coherentist
epistemologies always dothe specter of circularity. I
dont think I can say anything briefly about this worrythat will satisfy Machery. So let me just say this. I take
the candidate views here to be broadly either founda-
tionalist or coherentist. And, given what he says about
moral intuition, I doubt that Machery would be happy
with a moral foundationalism. So I urge him to play a
role in developing the coherentist picture.

Conclusion
Let me end, as I began, by stressing the very great
interest of these papers and of the issues they raise. I
am very grateful to all six authors for the care with
which they read my book and for drawing my
attention to much work with which I was unfamiliar.These papers confirm that there is a great deal of
work in the moral sciences for moral philosophers to
be thinking about. All of them are naturalist in
insisting that philosophy should take science seri-
ously. I endorse this form of naturalism heartily. We
need more experiments in ethics, more reflection on
them, more integration of experiment with moral
theory. The view that only science should be taken
seriouslyone name for which is scientismis
one I believe we all reject with equal enthusiasm.
Our growing intellectual division of labor makes itincreasingly important to try to scan from time to
time the vast vistas of our knowledge and seek
consilience. Philosophy is not the only perspective
from which one can pursue that task. But all of us
can agree that when philosophers neglect that project
they have abandoned one of our most valuable
intellectual traditions.11
