A Crisis of Faith puts forth one of the most comprehensive and accessible arguments for the claim that theism is false and faith-based belief is foolish.
Drawing from many disparate fields, including epistemology, evolutionary biology, textual criticism, the philosophy of mind and (what the author refers to as) secular eschatology, Crisis attacks the theistic position from multiple angles. In doing so, this book not only delineates established arguments against God's existence, but explores topics that no other atheists have yet considered - for instance, how might cognitive enhancements foment the further secularization of society?
Phil Torres puts together an overwhelmingly convincing case that religion ought to become a thing of the past: it's bad epistemology and, in a world marked by radical advances in genetics, nanotechnology and artificial intelligence, it greatly increases the likelihood of disaster.
This book is a must-read for anyone interested in the philosophical foundations of atheism and the many practical reasons it ought to be accepted.
