In his book "Good Men," author Arturo Pérez-Reverte explores the complex relationship between religion and human nature. He suggests that religion is the most significant form of deception created by humans, leading people to abandon rational thinking for irrational beliefs. This perspective challenges the common notion of faith as a guiding principle and instead positions it as a source of confusion and folly.

Pérez-Reverte raises critical questions about the impact of religious beliefs on individuals and society. By highlighting how common sense is often compromised in the face of dogma, he invites readers to reconsider the role of religion in shaping moral and ethical frameworks. His assertion encourages a deeper examination of how beliefs can cloud judgment, ultimately suggesting that true understanding lies in questioning rather than blindly accepting established doctrines.
