One of the most blasphemous philosophical documents ever written, Bertrand Russell's "Why I Am Not a Christian" is an eloquent critique of religious beliefs and dogma. Originally delivered as a lecture on March 6, 1927, the essay has since become one of Russell's most famous works and a key text in the literature of atheism and skepticism. In it, Russell dismantles comfortable answers religion provides to questions of morality, justice, and the meaning of life-offering instead rational alternatives based on accountability, freedom, and consciousness. It has influenced generations of thinkers and has become a classic in the literature of secular philosophy. Together with "Why I Am Not a Christian," What I Believe stands as an eloquent expression of Russell's well-known atheism. The ideas he concisely encapsulates present a compelling refutation of religion and belief in favor of reasoned thought. A defining work, this remarkable text remains the most succinct and compelling introduction to Russell's philosophical outlook. This Warbler Classics edition includes an extensively researched, detailed biographical timeline.
