In the following pages I have confined myself in the main to those problems of philosophy in regard to which I thought it possible to say something positive and constructive, since merely negative criticism seemed out of place. For this reason, theory of knowledge occupies a larger space than metaphysics in the present volume, and some topics much discussed by philosophers are treated very briefly, if at all. I have derived valuable assistance from unpublished writings of G. E. Moore and J. M. Keynes: from the former, as regards the relations of sense-data to physical objects, and from the latter as regards probability and induction. I have also profited greatly by the criticisms and suggestions of Professor Gilbert Murray.
One of his great works, and a must-read for any student of philosophy, The Problems of Philosophy was written in 1912 as an introduction to Russell's thought.
As an empiricist, Russell starts at the beginning with this question: Is there any knowledge in the world that is so certain that no reasonable man could doubt it? This, according to Russell, is where the work of philosophy begins. He covers topics such as reality, the nature of matter, inductive reasoning, truth, and the limits of philosophical knowledge.
As one of the greatest minds in Western philosophy, Russell's thoughts are profoundly informative and provocative and suitable for anyone wishing to expand his mind.
