Neuroscience is commonly thought to challenge the basic way we think of ourselves in ordinary thought, morality, and the law. This paper: (1) describes the legal institutions challenged in this way by neuroscience, including in that description both the political philosophy such institutions enshrine and the common sense psychology they presuppose; (2) describes the three kinds of data produced by contemporary neuroscience that is thought to challenge these commonsense views of ourselves in morals and law; and (3) distinguishes four major and several minor kinds of challenges that that data can reasonably be interpreted to present. The major challenges are: first, the challenge of reductionism, that we are merely machines; second, the challenge of determinism, that we are caused to choose and act as we do by brain states that we do not control; third, the challenge of epiphenomenalism, that our choices do not cause our actions because our brains are the real cause of those actions; and fourth, the challenge of fallibilism, that we do not have direct access to those of our mental states that do cause our actions, nor are we infallible in such knowledge as we do have of them.

7 On “indirect,” or “two-step,” utilitarianisms generally, see Alexander, Larry, “Pursuing the Good—Indirectly,” Ethics vol. 95 (1985), 315–32. Pinker's is a trait or motive kind of indirect utilitarianism. So-called “trait” or “motive” utilitarianism (according to which we should adopt those traits that in the long run will maximize utility), is usually associated with Brandt, Richard, “Towards a Credible Form of Utilitarianism,” in Brody, B., ed., Moral Rules and Particular Circumstances (Englewood Cliffs, NJ.: Prentice-Hall, 1970).

8 As many besides Pinker have noticed. See, e.g., Greene and Cohen, “Neuroscience Changes Nothing”; see also Dennett, Daniel, Elbow Room: The Varieties of Free Will Worth Wanting (Cambridge, MA: MIT Press, 1984), where in the last chapter Dennett unwittingly adds cheap compatibilism to the more genuine form of compatibilism expressed in the earlier chapters of his well-known compatibilist tract.

9 Clemenceau's celebrated simile was that military justice stands to justice as military music stands to music.

10 Moore, Placing Blame, 155–58, 160–63.

11 As Jack Smart, a trenchant but clear-headed act-utilitarian once put it, following a practice when it does not maximize utility to do so, is “blind rule-worship.” J. J .C. Smart, “Utilitarianism: For,” in Smart, J. J. C. and Williams, Bernard, Utilitarianism: For and Against (Cambridge: Cambridge University Press, 1973). David Lyons has classically shown that indirect utilitarianisms like Pinker's collapse either into such blind rule-worship or into a direct (or “act”) utilitarianism.

20 Chisholm, Roderickreintroduced the term (which is conventionally capitalized to avoid confusing it with the less technical idea of intentional action) into modern discussions. See hisPerceiving: A Philosophical Study (Ithaca, N.Y.: Cornell University Press, 1957), 120–70. For an update, see Perry, John, “Intentionality (II),” in Guttenplan, S., ed., Blackwell's Companion to the Philosophy of Mind (Oxford: Blackwell, 1994), 386–94.

22 Brentano, Franz, Psychologie vom Empirischen Standpunkt (Leipzig, 1874), a selection translated in Chisholm, R., ed., Realism and the Background of Phenomenology (Glencoe, Ill.: Free Press, 1960): “Every mental phenomenon is characterized by what the scholastics of the Middle Ages called Intentional Inexistence of an object …”

23 The basic motive for this “eliminativist-materialism” skepticism (based in philosophy rather than in scientific psychology) lies in the difficulty of individuating mental states with Intentional content in a way that any physical system could realize. See, e.g., Rorty, Richard, “The Brain as Hardware, Culture as Software,” Inquiry vol. 47 (2004): 231: “Beliefs cannot be individuated in such a way as to correlate with neural states.” The idea is that propositional content (if that is what it is) takes into account features of the world in such individuation, and such features “can't be in the head.” See generally Greenwood, John, ed., The Future of Folk Psychology (Cambridge: Cambridge University Press, 1991).

26 Whether there are two or three distinct states involved in practical rationality has been the subject of contemporary debate. Compare Davidson, Donald, “Intention,” in his Essays on Actions and Events (Oxford: Oxford University Press, 1980), with Bratman, Michael, Intention, Plans, and Practical Reason (Cambridge, MA: Harvard University Press, 1987). For reasons explored in Moore, Michael, Act and Crime: The Implications of the Philosophy of Action for the Criminal Law (Oxford: Clarendon Press, 1993), chap. 6, I favor Bratman's triad of distinct intentional states to Davidson's two.

27 A good explication of Aristotle's practical syllogisms in light of the contemporary philosophy of action is Nussbaum, Martha's dissertation, done under David Cooper's supervision and published asAristotle's De Moto Animalum (Princeton, N.J.: Princeton University Press, 1977).

31 David Sachs nicely charted how Freud's theory of defense mechanisms presupposed hidden norms of proportionality of emotional response. Sachs, David, “On Freud's Doctrine of the Emotions,” in Wollheim, R., ed., Freud: A Collection of Critical Essays (Garden City, N.Y.: Doubleday, 1974).

33 Usually termed the “causal theory of action,” a basic tenet of folk psychology. See Moore, Act and Crime; Moore, , “Renewed Questions About the Causal Theory of Action,” in Aguilar, J. and Buckareff, A., eds., Causing Human Action: New Perspectives on the Causal Theory of Action (Cambridge, MA: MIT Press, 2010). Jerry Fodor regards this as basic to the folk psychology: “If it isn't literally true that my wanting is causally responsible for my reaching … then practically everything that I believe about anything is false and it is the end of the world.” Fodor, Jerry, A Theory of Content and Other Essays (Cambridge, MA: MIT Press, 1990), 196.

45 Greene and Cohen, “Neuroscience Changes Nothing,” 1776. It is a bit disingenuous of Greene and Cohen to interpret Morse as dealing only at the level of legal doctrine. One of Professor Morse's lifetime projects has been to show that there is no presupposition of free will in the morals and metaphysics that make sense of the legal doctrines we have. See, for example, most recently, Morse, , “Determinism and the Death of Folk Psychology: Two Challenges to Responsibility From Neuroscience,” Minnesota Journal of Law, Science, and Technology, 9 (2008): 135.

46 The drive to Cartesian dualism from concerns about free will was classically charted in Ryle, Gilbert, The Concept of Mind (London: Hutcheson, 1949). Not all libertarians take refuge in dualism.

“The phenomenology of intention is poorly understood … the phenomenal content of intentions has hardly been studied experimentally. Reliable psychophysical procedures for investigating when and how the effects of an action are represented during preparation and intention would represent a major advance.”

67 Michael Gazzaniga quotes Roger Sperry thusly:

“the centermost processes of the brain with which consciousness is presumably associated are simply not understood. They are so far beyond our comprehension that no one I know of has been able to imagine their nature.”

68 Gazzaniga, quoted in Monastersky, Richard, “Religion on the Brain,” Chronicle of Higher Education, May 26, 2006, A–15. Gazzaniga can't claim 100 percent adherence to reductionism because of outliers within neuroscience like Sir John Eccles. See Eccles, , “The Initiation of Voluntary Movements;” Eccles, and Popper, , How the Self Controls Its Brain (Berlin: Springer-Verlag, 1994).

69 Consider, for example, the large promissory notes issued in this reductionist view of intentions:

“Intentions … are patterns of neural activity; or perhaps patterns of synaptic strength which are eventually played out into patterns of neural activity. Either kind of pattern clearly has both temporal and spatial extension, which means it must be located somewhere.”

127 Notice that the text phrases the matter comparatively, that is, that indeterministic chance gives us no more control, etc., than does deterministic causation, It may well be that one can imagine an indeterminism that is compatible with there being choice, effort, control, and therefore responsibility. See Kane, Robert, The Significance of Free Will (Oxford: Oxford University Press, 1998), chap. 8. But such compatibility will have no leg up on a like compatibility of deterministic causation with that same choice, effort, control, and therefore responsibility.

“the feeling of agency … is a mark of selfhood … the conscious awareness of unconsciously monitored actions is the means by which our actions are experienced as subjectively real, willed, and owned. Consciousness is thus embodied: it is through action that we become conscious of ourselves as “distinct selves.” (Emphasis in original, citation omitted).

145 Pockett, “The Neuroscience of Movement,” 19–21.

146 Wegner gets the universal claim only by separating what is referred to by “will” into the phenomenal (or conscious) will, and the empirical will. If the claim is that the conscious will (i.e., phenomenology alone, with no physical realization) never causes movement, all can agree (for this would be a dualism). But Wegner's data on what he calls the illusion of control cases is much more interesting than this; the data suggest that in such cases, willing as such (the deep reference being to its essentially physical nature) does not cause the behavior. The only point in the text is that this more interesting point is also limited to the data explored by Wegner, viz, the illusion of control cases.

147 As Wegner notices in his discussion of Libet's findings. Wegner, Illusion of Conscious Will, 49–55; Wegner, “Author's Resopnse,”684: “The idea of ICW is not dependent on Libet's finding … this is because ICW … is not about whether thought causes action. It is about whether the experience of conscious will reflects such causation.”

159 The beginnings of my answers to some of these challenges may be found in Moore, , “Libet's Challenge(s) to Responsible Agency,” in Sinnott-Armstrong, Walter and Nadel, Lynn, eds., Conscious Will and Responsibility (Oxford: Oxford University Press, 2010), 207–34, and in lecture form, at, (Nineteenth Annual Center for Advanced Study Lecture, September, 2009), and http://www/, (Lecture to the Institute for Legal Philosophy and Public Affairs, Albert-Ludwigs University, Freiburg-im-Breisgau, Germany, March, 2010). My colleagues Al Mele, Adina Roskies, and Stephen Morse have also done recent work that tracks some of these concerns. See Mele, Alfred, Free Will and Luck (Oxford: Oxford University Press, 2006); Mele, Alfred, Effective Intentions: The Power of Conscious Will (Oxford: Oxford University Press, 2009); Roskies, Adina, “Neuroscientific Challenges to Free Will and Responsibility,” Trends in Cognitive Science, vol. 10, no. 9 (2006),; Morse, Stephen, “Determinism and the Death of Folk Psychology: Two Challenges to Responsibility from Neuroscience,” Minnesota Journal of Law, Science, and Technology, 9 (2008): 135.

* In the researching and writing of this essay I have benefitted from the generous support, both financial and otherwise, of the MacArthur Foundation's Project in Law and Neuroscience 2007–2010. The paper is a (considerably) expanded version of the Responsibility Group Working Paper on the Challenges of Neuroscience, presented by me to the winter 2010 Santa Monica meeting of the Criminal Responsibility and Prediction Research Network of the MacArthur Foundation's Law and Neuroscience Project. My thanks go to my colleagues in the Network for their suggestions and comments. The essay has since been presented to the Workshop in Law and Philosophy, University of Texas, Austin and to the Conference on Law and the Science of Moral Judgment, Centre for the Study of Mind in Nature, University of Oslo, Norway. My thanks go to the participants at these two presentations for their helpful comments as well as to the other contributors to this volume. My particular thanks go to Robert Kane, who was my commentator at the University of Texas, and to Michael Gazzaniga and Stephen Morse, each of whom read and commented separately on this paper.
