Our Knowledge of the External World as a Field for Scientific Method in Philosophy

Russell here argues that philosophy must abandon its grand metaphysical ambitions and instead adopt the rigorous methods of science and logic. Written in 1914, this groundbreaking work proposes that philosophical problems, particularly those concerning knowledge of the external world, can be tackled through careful analysis rather than speculation. Russell examines how mathematical physics constructs its concepts from sensory data, and how philosophy might learn from this scientific practice. He critiques traditional philosophy for its overreaching claims while offering a transformative alternative: a method grounded in logic, observation, and the humble acknowledgment of what we can actually know. This book captures Russell at his most ambitious, attempting to remake philosophy in science's image, and remains a foundational text for understanding how analytic philosophy came to dominate Anglo-American thought.
