Do Criminal Minds Cause Crime? Neuroscience And The Physicalism Dilemma, John A. Humbach

Elisabeth Haub School of Law Faculty Publications

The idea that mental states cause actions is a basic premise of criminal law. Blame and responsibility presuppose that criminal acts are products of the defendant's mind. Yet, the assumption that mental causation exists is at odds with physicalism, the widely shared worldview that “everything is physical.” Outside of law, there is probably no field of secular study in which one can seriously assert that unseen nonmaterial forces can cause physical events. But if physicalism is true then a fundamental premise of modern criminal justice must be false, namely, that criminals deserve punishment because their crimes are the products of …

Neuroscience, Justice And The "Mental Causation" Fallacy, John A. Humbach

Mental causation is a foundational assumption of modern criminal justice. The law takes it for granted that wrongdoers “deserve” punishment because their acts are caused by intentions, reasons and other mental states. A growing body of neuroscience evidence shows, however, that human behavior is produced by observable physiological activity in the brain and central nervous system--all in accordance with ordinary physical laws. Beyond these ordinary physiological interactions and processes, no hypothesis of mental causation is required to causally explain behavior.

Despite the evidence, neuroskeptics insist that intentions, reasons and other mental states can play a causal role in producing human …
