page 310 note * The “implicit definitions” (or “definitions by postulates”) so frequently used by Hilbert do not, in general, define things, and, though axioms are necessary at the beginning of logic, they have shown themselves to be unnecessary at the beginnings of arithmetic and geometry (cf. Russell, The Principles of Mathematics, Cambridge, 1903, pp. v, 4-5, 11, 429-430; Couturat, Les Principes des Mathématiques, Paris, 1905, pp. 157-159).
