Ideas of William S. Jevons, by Text

[British, 1835 - 1882, Born in Liverpool.]

1879 The Principles of Science
p.156 p.22 I hold that algebra and number are developments of logic
     Full Idea: I hold that algebra is a highly developed logic, and number but logical discrimination.
     From: William S. Jevons (The Principles of Science [1879], p.156), quoted by Gottlob Frege - Grundlagen der Arithmetik (Foundations) §15
     A reaction: Thus Frege shows that logicism was an idea that was in the air before he started writing. Riemann's geometry and Boole's logic presumably had some influence here.
