'Plain' persons tend to accept that free will exists and is inconsistent with determinism, but this commonsense position is widely debunked by professional philosophers and cognitive scientists. In this special issue of the Journal of Consciousness Studies David Hodgson defends a simple, robust account of the plain person's position on free will, and intends it to support equally robust views of personal responsibility for conduct. In a lively debate his ideas are discussed and challenged by ten philosophers and scientists of varying opinions, including Robert Kane, Henry Stapp, and veteran philosopher of mind J.J.C. Smart, with a response by the principal author.
