Addiction illuminates concept of ‘free will’

Whether humans possess free will or whether their actions are determined by something outside their conscious control is one of the most persistent problems in philosophy.

In a lecture May 9, Steven E. Hyman warned his audience that he would not attempt to resolve the issue of free will in an ultimate sense. He did, however, have some fascinating insights regarding a special instance of the free-will dilemma — namely, the neurochemical mechanisms that result in the loss of free will when a person becomes addicted to drugs.

“Drug addiction has been used as a yardstick for reward-based behavior,” said Hyman. “With addiction, there is a narrowing of life focus in that drug-seeking crowds out all other motivations and goals.”
