Bertrand Russell
British philosopher Bertrand Russell made a number of significant contributions to the field, including helping to found the area of inquiry known as analytical philosophy and advancing the practice of logic. He also helped to influence the development of the philosophy of science by focusing on empiricism in new ways. The underpinnings of Russell's views on science and metaphysics are set forth in Our Knowledge of the External World as a Field
...One of the keenest philosophical minds of the twentieth century, Bertrand Russell wrote a number of classic volumes on the subject, including the venerated survey A History of Western Philosophy. In this volume, Russell takes on the subjects of religion and logical reasoning with his characteristic elegance and penetrating insight.
Though chiefly recognized as a towering figure in twentieth-century philosophy, Bertrand Russell also focused his attention on matters related to politics, culture, and society. The Practice and Theory of Bolshevism attempts to place the Russian revolutionary movement in a broader historical and cultural context, as well as to elucidate its philosophical foundations.
