In this 2005 book, Tim O'Keefe reconstructs the philosopher Epicurus' theory of freedom.In this book, Tim O'Keefe reconstructs the philosopher Epicurus' (341 271/0 BCE) theory of freedom. Epicurus' theory has attracted much interest, but our attempts to understand it have been hampered by reading it anachronistically as the discovery of the modern problem of free will and determinism. O'Keefe argues that the sort of freedom which Epicurus wanted to preserve is significantly different from the 'free will' which philosophers debate today, and that in its emphasis on rational action it has much closer affinities with Aristotle's thought than with current preoccupations.In this book, Tim O'Keefe reconstructs the philosopher Epicurus' (341 271/0 BCE) theory of freedom.
