Although many psychiatrists regard psychopathy as a coherent scientific construction, some clinicians and philosophers regard it as irrelevant. According to the latter, psychopathy is nothing more than a means of social control. The present study focuses on the issues of the neurological bases and moral responsibility related to psychopathy. While neuroscience aims to identify dysfunctions in psychopaths, action theory and ethics tend to vindicate the hypothesis of the moral irresponsibility of the psychopath. However, rather than reinforcing the concept of psychopathy, (...) recent results in neuroscience tend to stress its incoherence. Philosophical speculations on psychopaths’ responsibility are not sufficiently empirically informed and seem to announce endless ethical debates. (shrink)
