    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

    Safro Kwame [6].

    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

    Invisible Entities.Rev: Patterns of Thought in Africa and the

    West by Robin Horton Times Literary Supplement (July 2

    1993): 7.

    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

    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
