Book excerpt: This book is the first full-length treatment of the philosophical problem of fatalism, the thesis that the laws of logic alone suffice to prove that no person ever acts freely. After a critical examination of the history of the problem, from Aristotle through Stoic and medieval thought, Cahn analyzes contemporary discussions of the issue, revealing how a belief in free will is logically connected to specific assumptions about the truth-value of propositions and the nature of time.
