About this book

One of the most important conservative voices of the last century takes on the dangers of secularism, perhaps the most important issue in our lives. Your beloved dog and a stranger are drowning. Who do you try to save first? Every time famed radio host, New York Times bestselling author, and Co-founder of PragerU, Dennis Prager, has asked this question, one-third of the audience voted for the dog, one-third for the stranger, and one-third was not sure.

We live in an era when people increasingly make moral judgments based on their emotions. But if feelings determine what is right and wrong, then whether murder, rape, and theft are wrong is no more than an opinion. Why are those who riot and destroy property wrong, especially if they feel their behavior is justified? Prager explains that without objective morality, the world will descend into chaos, with every individual engaging in any behavior they feel is right. For fifty years, Dennis Prager, one of the best-known public intellectuals in the Western world, has explored the vital role Judeo-Christian values play in shaping individual lives and entire societies. In If There Is No God, he engages in provocative and sometimes heated exchanges with questioners who offer some of the greatest challenges he has faced concerning how one determines good and evil and why one’s feelings can be life-enhancing yet morally unimportant. If God exists, why doesn’t He punish the unjust? Why does He allow the innocent to suffer? How can religion better the human condition when so many of the religious are often immoral? These timeless questions are in urgent need of answers. The reader need not be religious or even believe in God to find the arguments and debates in this book compelling and meaningful. All one needs is reason to appreciate the ideas Prager presents. Thought-provoking, important, and accessible for the devout and the skeptic, If There Is No God is a guide for anyone seeking clarity in a morally troubled age.
