RESPONSIBLE CHOICES, DESERT-BASED LEGAL INSTITUTIONS, AND THE CHALLENGES OF CONTEMPORARY NEUROSCIENCE*
Published online by Cambridge University Press: 14 December 2011
Abstract
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.

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)Google Scholar.

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): 231CrossRefGoogle Scholar: “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)Google Scholar.

26 Whether there are two or three distinct states involved in practical rationality has been the subject of contemporary debate.

“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.”

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. 8Google Scholar. But such compatibility will have no leg up on a like compatibility of deterministic causation with that same choice, effort, control, and therefore responsibility.

140 As Freud is reported to have said (at an awards ceremony in 1927 celebrating his “discovery of the unconscious”), “My only claim to discovery is by being ill-read.” On Freud's non-psychoanalytic antecedents, see Moore, Law and Psychiatry, 126–34, 250–51, 265, 327.

144 Dennett, Content and Consciousness, 90–96. The role of consciousness (in the sense of privileged access) is also emphasized by Choudhury, Suparna and Blakemore, Sarah-Jayne, “Intentions, Actions, and the Self,” in Pockett, S., Banks, W., and Gallagher, S., eds., Does Consciousness Cause Behavior? (Cambridge, MA: MIT Press, 2006), 48–49Google Scholar as crucial to ownership of actions and self-construction:
“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.”
