9875 | Frege was completing Bolzano's work, of expelling intuition from number theory and analysis [Frege] |
6426 | Intuitionism says propositions are only true or false if there is a method of showing it [Russell] |
8728 | Intuitionist mathematics deduces by introspective construction, and rejects unknown truths [Brouwer] |
12454 | Intuitionists only accept denumerable sets [Brouwer] |
