Prominent mathematicians that were well known Platonists, include: - Bertrand Russell <https://en.wikipedia.org/wiki/Bertrand_Russell>,[12] <https://en.wikipedia.org/wiki/Platonism#cite_note-SEP-P-12> - Alonzo Church <https://en.wikipedia.org/wiki/Alonzo_Church>,[12] <https://en.wikipedia.org/wiki/Platonism#cite_note-SEP-P-12> - Kurt Gödel <https://en.wikipedia.org/wiki/Kurt_G%C3%B6del>,[12] <https://en.wikipedia.org/wiki/Platonism#cite_note-SEP-P-12> - W. V. O. Quine <https://en.wikipedia.org/wiki/W._V._O._Quine>,[12] <https://en.wikipedia.org/wiki/Platonism#cite_note-SEP-P-12> - David Kaplan <https://en.wikipedia.org/wiki/David_Kaplan_(philosopher)> ,[12] <https://en.wikipedia.org/wiki/Platonism#cite_note-SEP-P-12> - Saul Kripke <https://en.wikipedia.org/wiki/Saul_Kripke>,[12] <https://en.wikipedia.org/wiki/Platonism#cite_note-SEP-P-12> - Edward Zalta <https://en.wikipedia.org/wiki/Edward_Zalta>.[13] <https://en.wikipedia.org/wiki/Platonism#cite_note-13> - John Conway - Roger Penrose https://plato.stanford.edu/entries/platonism/ https://en.wikipedia.org/wiki/Platonism#Modern_Platonism https://www.quora.com/What-is-your-opinion-on-mathematical-Platonism https://www.youtube.com/watch?v=TKlPj_qGIt8 So it is certainly wrong to call this "my theory", it is the "standard theory", in mathematics (and arguably in other fields as well). Most people seem to believe math is discovered rather than invented. Jason -- You received this message because you are subscribed to the Google Groups "Everything List" group.
