In this wide-ranging collection of articles, essays, and speeches, George H Smith analyses atheism and its relevance to society today. The featured essay in this volume provides a full analysis of Ayn Rand’s unique contribution to atheism, explaining how her objectivist metaphysics and laissez-faire economic principles rested on a purely godless worldview. Several chapters address the evolution of atheism; arguments in favour of religious toleration; the efforts of early Church fathers to discredit Roman polytheism and how these arguments can be used with equal force against later Christian descriptions of God; and, a survey of the contributions to free-thought made by the deists of the 18th and 19th centuries. With incisive logic and considerable wit, Smith ties atheism to reason and argues that reason itself can be a moral virtue. In one penetrating chapter, Smith salutes three Christian theorists who he believes embody the spirit of reason: Thomas Aquinas, Desiderius Erasmus, and John Locke. This is followed by a philosophical drubbing of his ‘least favourite Christians’ - St Paul, St Augustine, and John Calvin. In subsequent chapters, Smith examines religion and education; addresses the 20th century fundamentalist revival; offers suggestions on how to debate atheism with religious believers; critiques ‘new religions’, including pop therapy, EST, and transactional analysis; and, provides a comprehensive bibliographic essay on the literature of free-thought.
