The Collected Papers of Bertrand Russell, Volume 2 : The Philosophical Papers 1896-99 (The Collected Papers of Bertrand Russell)

The 1896-1899 papers, few of which were published in Russell's lifetime, concentrate primarily on physics, arithmetic and the concept of quantity. Several views that later became well-known in his The Principles of Mathematics actually originate in his earlier work, and though incomplete,An Analysis of Mathematical Reasoning, forms a centrepiece of the volume.
