Bertrand Arthur William Russell, 3rd Earl Russell, was a British philosopher, logician, mathematician, historian, writer, essayist, social critic, political activist, and Nobel laureate. In the early 20th-century, Russell led the British "revolt against idealism". He is considered one of the founders of analytic philosophy along with his predecessor Gottlob Frege, colleague G. E. Moore and protégé Ludwig Wittgenstein. He is widely held to be one of the 20th century's premier logicians. Russell was a prominent anti-war activist and he championed anti-imperialism. He went to prison for his pacifism during World War I. Bertrand Russell did not consider himself an expert on ethics and religion, and it is true that his writing on these subjects lacks the originality and sophistication of his philosophical work on mathematics. His criticisms of religion are often similar – in essence, if not in tone – to opinions voiced by contemporary atheists: he argued that religious beliefs cause wars and persecution, are moralistic and oppressive, and foster fear. However, it is precisely for this reason that it is worth looking again at Russell's rejection of Christianity. Anyone concerned with defending religion against its typical modern detractors must recognise Russell as a worthy opponent, for he was an intelligent, principled and humane man of the world who undoubtedly led a meaningful life.
