Truth and experience of truthvery prophecy looks today like an historical oddity because, as a matter of fact, intuitionism has survived. Nevertheless, the sense in which it has survived needs clarification. The most striking feature of the present situation of intuitionism is that some sort of peaceful coexistence with classicHemodialysis 发表于 2025-3-23 21:24:10

Gödel, constructivity, impredicativity, and feasibilityeen told and analyzed by others, for instance in (Kreisel 1987b) and (Tait 2006a, b). More modestly, our first aim here is to present a different appearance of a ghost during that story, the one of impredicativity, and to show that only one case is to be taken seriously from a strict anti-realist poHeart-Attack 发表于 2025-3-24 17:49:25

The Hilbert-Brouwer controversy resolved?he most obvious answer is: the Beth models for intuitionistic propositional and predicate logic. I would like to remind you of a certain picture that we all use when thinking in terms of possible worlds, namely the picture in which we are always at a certain stage, considering a number of possible fJuvenile 发表于 2025-3-24 23:42:33
Proof theory and Martin-Löf Type Theoryordinal notation systems. In order to obtain a satisfactory solution to the consistency problem, this reduction needs to be supplemented by a second step, namely by proofs of the well-foundedness of the ordinal notation systems in ‘safe’ theories, for which one has an argument that everything shown
