This monograph offers a new argument concerning free will and moral responsibility. Double identifies hierarchical compatibilism - a view espoused by such philosophers as Frankfurt, Neely, Watson, Levin, and Dennett - as the most plausible account of free will, showing how compatibilism can be successfully defended against incompatibilist objections. He goes on, however, to demonstrate that even the compatibilist account of free will ultimately faces insuperable objections, and concludes that free will is an essentially incoherent notion.
