The Problems of Philosophy

The Problems of Philosophy is a 1912 book by the philosopher Bertrand Russell, in which the author attempts to create a brief and accessible guide to the problems of philosophy. He 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. 
In this little book Russell has provided an intelligible and stimulating guide to a branch of knowledge which is often mistakenly considered too abstruse for the lay mind. He has confined himself chiefly to those problems of philosophy concerning which he thought it possible to say something positive and constructive. For this reason, theory of knowledge occupies a larger space than metaphysics and some topics much discussed by philosophers are treated briefly.
