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.

神は死んだ(ニーチェもね)。いまや世界のありようを解明するのは科学である。万物は詰まるところ素粒子のダンスにすぎないのだ。こうした世界観のもとでは、哲学が得意げに語ってきたものたちが、そもそも本当に存在するのかさえ疑わしい。「ことばの意味とは何か」「私たちは自由意志をもつのか」「道徳は可能か」、そして「人生に意味はあるのか」...すべての哲学問題は、根底から問い直される必要がある!科学が明らかにした世界像のただなかで人間とは何かを探究する、最もラディカルにして普遍的な入門書。他に類を見ない傑作です。
