In Letters to an Atheist, esteemed philosopher and author Peter Kreeft corresponds with a young atheist who is wrestling with the question of God. Together they work through some of the primary reasons people don’t believe in God, including violence committed in the name of religion, the problem of evil, and more. They also discuss many of the reasons for belief, including love, miracles, and the relationship between religion and science.

The debate between atheists and theists today is often strident and angry, and understandably so—the debate encompasses fundamental questions about how we live our lives. As Kreeft writes, “if God does not exist, then religion is the biggest hoax, the biggest myth, the biggest lie in the history of the world.” However, Letters to an Atheist showcases a respectful exploration of some of life’s biggest questions, trying to understand the opposing point of view. With characteristic warmth and clarity, Kreeft’s letters offer believers and non-believers alike much to consider.

"The book makes amazing and convincing points on possibly the most important topic of all time: Does God exist? . . . . I really did like this book and learned a tremendous amount from Kreeft on how to dialogue with an atheist. Formatting the book in written letters was brilliant; the book is short to begin with and the conversational tone made it not only a quick read, but it really got me invested in the relationship between Kreeft and Michael and Michael’s progress from atheism." - Our Sunday Visitor

"When a young woman expressed concern about her atheist brother, Kreeft (philosophy, Boston Coll.; Catholic Christianity; Making Sense out of Suffering) offered to enter into correspondence with him. In this thoughtful defense of theism, the author spells out the grounds for his belief in God and imagines how the woman’s brother might reply. Assuming his interlocutor’s (and reader’s) intelligence and understanding of basic logic and philosophical terminology, Kreeft distinguishes different types of atheism; addresses the problems he sees in materialism, naturalism, and scientism; and responds to traditional antitheistic arguments. Only in the last 20 pages does he go offtrack, with sound-bite defenses of traditional Catholic doctrines on sexuality and unconvincing dismissals of the Church’s roles in historical violence and recent child-abuse scandals. Kreeft gives most credence to first-cause and moral arguments for God’s existence, stressing that both truth and goodness must be grounded in the nature of reality. Verdict Given that the atheist’s side of the correspondence is fictional, it comes as no surprise that this warm, philosophical defense of faith in God will speak more to believers’ inner doubts than to actual skeptical questioners." - Library Journal

"Kreeft’s letters demonstrate how to hold charitable, fruitful dialogue with unbelievers. Kreeft covers all the famous arguments for God’s existence, including Aquinas’ Five Ways and the arguments from desire, morality, fine tuning, and Big Bang cosmology. But he does so with a refreshing friendliness. The letters lack the polemical and turgid prose seen in many books on atheism. Instead, his book is sharp, witty, and warm, and one of the first I’d recommend to anyone wrestling with faith." - Fox News
