Though Plantinga later modified some of his views, particularly on the soundness of the ontological argument and on the nature of epistemic rationality, he still stands by the basic theses of the book.
The book explores the rationality of belief in God, as conceived in the Hebrew-Christian tradition.
In Part II, he considers and rejects some major arguments against belief in God, including the problem of evil, the paradox of omnipotence, and verificationism.
The book has the following chapters: Part I: Natural Theology Part II: Natural Atheology Part III: God and Other Minds Michael A. Slote in The Journal of Philosophy[2] considered that "[t]his book is one of the most important to have appeared in this century on the philosophy of religion, and makes outstanding contributions to our understanding of the problem of other minds as well".
"[3] Plantinga's response to the problem of evil – the so-called free will defense, which argues that it is possible that God could not have created a world with a better balance of good over evil than does the actual world – provoked considerable scholarly discussion.
