Genes, free will, and criminal responsibility.
Advances in human genetics have raised the possibility that genetic mechanisms can explain various aspects of human behavior. It has been suggested that such genetic explanations would tend to diminish responsibility for one's actions. In this paper I argue that the genetic approach adds little to our understanding of free will, determinism, and responsibility. Even though human beings are material systems obeying the laws of the physical and biological sciences, their behavior may still be unpredictable and essentially undetermined. Moreover, with few exceptions, behavior influenced by genes is no more deterministic than is behavior influenced by the environment. An analysis of the genetic and environmental influences and the complex interactions between them reveals a certain symmetry between genetic and environmental explanations of behavior. Consequently, any argument concerning the relevance of a genetic excuse to a criminal defense will be equally applicable to an environmental excuse.
