Why it’s here. The title essay of this collection was delivered as a lecture in 1927, at a time when publicly denying Christianity was still socially costly and professionally risky. Russell did not find it risky — he had been controversial for so long that one more controversy hardly registered — but he delivered the lecture with a care that suggests he understood its importance. In clear, conversational prose, he examined the standard arguments for the existence of God, found each deficient, argued that Christ’s moral teaching was not as admirable as its reputation, and concluded that religion was primarily a product of fear rather than genuine inquiry. The essay is not the last word on any of these topics, but it is among the most cleanly argued treatments of them in the English language, and it remains, nearly a century later, one of the best entry points to the intellectual case against religious belief.
What it offers. The collection spans several decades of Russell’s thought and covers more than just theology: there are essays on free thought and official propaganda, on why Russell was not a Communist, on the value of skepticism, and on the good life as conceived without religion. The variety is itself part of the book’s value — it shows that freethinking is not merely a negative position (rejection of religion) but part of a broader intellectual attitude. Russell’s prose style in these essays is at its most accessible: spare, precise, occasionally sardonic, always in complete control. His analysis of the cosmological and first-cause arguments for God’s existence — pointing out that if everything requires a cause, God requires one too, and if we allow for something that requires no cause, why not allow the universe itself? — is the sharpest brief treatment of those arguments available to a general reader.
A word of caution. The philosophy of religion has advanced considerably since 1927, and Russell’s treatment of the arguments for God’s existence is less complete than it would need to be as a contemporary account. More sophisticated versions of the cosmological and ontological arguments — particularly those developed by Alvin Plantinga and Richard Swinburne in the second half of the 20th century — require more than Russell’s brief rebuttals. Readers who take seriously the task of evaluating religious belief should use this book as a starting point and follow it with more recent philosophical literature on both sides. Russell is the best possible beginning; he is not the end.
