The Problems of Philosophy

The Problems of Philosophy (1912) is one of Bertrand Russell's
attempts to create a brief and accessible guide to the problems of philosophy.
Focusing on problems he believes will provoke positive and constructive
discussion, Russell concentrates on knowledge rather than metaphysics.

Russell guides the reader through his famous 1910 distinction between
"knowledge by acquaintance and knowledge by description" and introduces
important theories of Plato, Aristotle, René Descartes, David Hume, John Locke,
Immanuel Kant, Georg Hegel and others to lay the foundation for philosophical
inquiry by general readers and scholars alike.
