Single Idea 12453

[filed under theme 6. Mathematics / C. Sources of Mathematics / 10. Constructivism / b. Intuitionism ]

Full Idea

Neo-intuitionism sees the falling apart of moments, reunited while remaining separated in time, as the fundamental phenomenon of human intellect, passing by abstracting to mathematical thinking, the intuition of bare two-oneness.

Gist of Idea

Neo-intuitionism abstracts from the reuniting of moments, to intuit bare two-oneness

The 10 ideas from Luitzen E.J. Brouwer

Intuitionist mathematics deduces by introspective construction, and rejects unknown truths [Brouwer]
Intuitonists in mathematics worried about unjustified assertion, as well as contradiction [Brouwer, by George/Velleman]
Scientific laws largely rest on the results of counting and measuring [Brouwer]
Our dislike of contradiction in logic is a matter of psychology, not mathematics [Brouwer]
Intuitionists only accept denumerable sets [Brouwer]
Neo-intuitionism abstracts from the reuniting of moments, to intuit bare two-oneness [Brouwer]
Brouwer regards the application of mathematics to the world as somehow 'wicked' [Brouwer, by Bostock]
Mathematics is a mental activity which does not use language [Brouwer, by Bostock]
Brouwer saw reals as potential, not actual, and produced by a rule, or a choice [Brouwer, by Shapiro]
For intuitionists excluded middle is an outdated historical convention [Brouwer]
