Note 153 — Chapter IV · SPACE AND TIME

Otherwise, conceptual space and time are, as we have seen, derivatives of the number-series, and we have already learned that the number-series leads to the problem of summing an endless series, and is therefore not an adequate way of representing ultimate Reality. (Bk. II. chap. 4, § 10). Another form of the same difficulty would be that conceptual space and time are applications of the numerical series,—but application to what? To a material which is already spatial and temporal. All these puzzles are only different ways of expressing the essential relativity of space and time. But see the anti-Kantian view in, e.g., Couturat, L’Infini Mathématique, pt. 2.
