This book is considered another important milestone in the history of Freethought literature. It emphasizes the untenable position of the individual who thinks, because he is free from the trammels of religious superstition, that everyone else is free from its influence. The author shows that supernaturalization has been the historical enemy of human progress. Contents: in these godless days; evils of supernaturalism; man's place in nature; man's place in the universe' superior basis of natural ethics.
