This book provides an overview of the very latest developments in the freedom of will debate, including a discussion of the ramifications of brain research for the problem of freedom. The author, Geert Keil, also presents an original thesis. He disagrees with the consensus among philosophers that the power to act otherwiseis irreconcilable with a scientific world view. He argues instead that although we are unable to change the laws of nature and are not the “first movers,” neither is an absolute requirement for free will. This new, revised edition also discusses the debate sparked by the initial publication of the book.
