ABSTRACT
11.1. Short account of the three parts of ‘Principia Mathematica’. The high-water mark of the first stages in the growth of Mathematical Logic, the stages from 1847 to 1910, was Whitehead and Russell’s Principia Mathematica (first part, 1910; second part, 1912; third part, 1913). This is a great book, great in quality and great in size—its three parts have more than 2,000 pages. In it are united into one general system the Boole-Schroeder algebra of logic and the theories, differently purposed from that and from one another, of Frege, Cantor and Peano.
