Our Knowledge of the External World is a compilation of lectures
Bertrand Russell delivered in the US in which he questions the very
relevance and legitimacy of philosophy. In it he investigates the
relationship between 'individual' and 'scientific' knowledge and
questions the means in which we have come to understand our physical
world. This is an explosive and controversial work that illustrates
instances where the claims of philosophers have been excessive, and
examines why their achievements have not been greater.
