"Thousands of philosophers—from the ancient Greeks to modern thinkers—have defended atheism, but none more comprehensively than Martin. His lengthy arguments, detailed and incisive, are sharpened by modern developments in logic and inductive reasoning and by special attention to contemporary thinkers whose subtle writings are unknown to the general public.... Atheists should read it to bolster their creed, and theists should read it to test their faith against the deadly force of Martin's attack."
—Martin Gardner, The Humanist
