Dualism and Doctrine

What kinds of harm among those that tortfeasors inflict are worthy of compensation? Which forms of self-incriminating evidence are privileged against government compulsion? What sorts of facts constitute a criminal defendant’s intent? Existing doctrine pins the answer to all of these questions on whether the injury, facts, or evidence at stake are "mental" or "physical." The assumption that operations of the mind are meaningfully distinct from those of the body animates fundamental rules in our law.A tort victim cannot recover for mental harm on its own because the law presumes that he is able to unfeel any suffering arising from his mind, by contrast to his bodily injuries over which he exercises no control. The Fifth Amendment forbids the government from forcing a suspect to reveal self-incriminating thoughts as a purportedly more egregious form of compulsion than is compelling no less incriminating evidence that comes from his body. Criminal law treats intentionality as a function of a defendant’s thoughts altogether separate from the bodily movements that they drive into action. This Essay critically examines the entrenchment of mind-body dualism in the Supreme Court doctrines of harm, compulsion, and intentionality. It uses novel insights from neuroscience, psychology, and psychiatry to expose dualism as empirically flawed and conceptually bankrupt. We demonstrate how the fiction of dualism distorts the law and why the most plausible reasons for dualism’s persistence cannot save it. We introduce an integrationist model of human action and experience that spells out the conditions under which to uproot dualism’s pernicious influence within our legal system.
