Single Idea 10047

[filed under theme 6. Mathematics / C. Sources of Mathematics / 6. Logicism / b. Type theory ]

Full Idea

Unfortunately, Russell's new logic, as well as preventing the deduction of paradoxes, also prevented the deduction of mathematics, so he supplemented it with additional axioms, of Infinity, of Choice, and of Reducibility.

Gist of Idea

Russell's improvements blocked mathematics as well as paradoxes, and needed further axioms

A Reaction

The first axiom seems to be an empirical hypothesis, and the second has turned out to be independent of logic and set theory.
