Who's flying the plane: serotonin levels, aggression and free will.

The present paper addresses the philosophical problem raised by current causal neurochemical models of impulsive violence and aggression: to what extent can we hold violent criminal offenders responsible for their conduct if that conduct is the result of deterministic biochemical processes in the brain. This question is currently receiving a great deal of attention among neuroscientists, legal scholars and philosophers. We examine our current knowledge of neuroscience to assess the possible roles of deterministic factors which induce impulsive aggression, and the extent to which this behavior can be controlled by neural conditioning mechanisms.

Loathing the sinner, medicalizing the sin: why sexually violent predator statutes are unjust.

In seventeen states, persons convicted of one or more sexually violent offenses may be involuntarily civilly committed at the end of their criminal terms if they suffer from a mental disorder that renders them likely to reoffend sexually. These statutes place the burden on states to show that the sex offender meets the United States Constitutional standard of dangerousness. The key to proving dangerousness is proof of a mental disorder.
