MATHEMATICS (MS 1-278)
The comments on Russell's work are as follows: ". . . true in the main" and "throughout, however, he betrays insufficient reflection on the fundamental conceptions of the subject," with the "primary difficulty . . . his not having begun with a thorough examination of the elements; . . . the ultimate analytic of thought." The major part of the manuscript concerns CSP's own analytic of thought (theory of signs).
