MARCH’S FEATURED TEXT

Grab a download!

The Problems of Philosophy is a 1912 book by British philosopher and logician Bertrand Russell.

Russell wrote it as a quick and accessible guide to some of the issues of philosophy. The reader is introduced not only to Russell's theories but also those of other philosophers such as Hume, Locke and Kant. The selection of problems concentrates on the theory of knowledge (epistemology) rather than metaphysics. This involves the distinction between types of knowledge, an important part of Russell's philosophy, and to what degree something can truly be known with any certainty.

The text on Wikisource also features an accompanying audiobook version from LibriVox.

When we have realised the obstacles in the way of a straightforward and confident answer, we shall be well launched on the study of philosophy—for philosophy is merely the attempt to answer such ultimate questions, not carelessly and dogmatically, as we do in ordinary life and even in the sciences, but critically, after exploring all that makes such questions puzzling, and after realising all the vagueness and confusion that underlie our ordinary ideas.
