 Russell’s analysis of traditional arguments in favour of the existence of God appears in both his popular and his philosophical writings. In his book on Leibniz, he discusses Leibniz’s treatment of several such arguments, noting that they are “the weakest part in Leibniz’s philosophy, the part most full of inconsistencies” (1900, sec. 106, p. 172). In his more popular writings, he repeatedly emphasizes his views about religion, noting that “The fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd” (1929, 58). In his 1922 booklet Free Thought and Official Propaganda, he tells his readers that “I am myself a dissenter from all known religions, and I hope that every kind of religious belief will die out” (1922a, 1). Later, in his 1941 collection of essays Let the People Think, he adds that “modern science gives us no indication whatever of the existence of the soul” (A1941, 113), and in the preface to his 1957 book Why I Am Not a Christian and Other Essays on Religion and Related Subjects, he notes that  “I am as firmly convinced that religions do harm as I am that they are untrue” (1957, xi).
