The difficulty involved in a constructive theory of sets is that in contrast with axiomatic set theory, the lutizen of set cannot be taken as primitive, but must be explained. Brouwer’s little book Life, Art and Mysticism ofwhile not developing his foundations of mathematics as such, is a key to those foundations as developed in his dissertation on which he was working at the same time and which was finished two years later.

Staal Amsterdam,pp. Mannoury — was a philosopher, mathematician, psychoanalyst, accountant, and political activist.

He quickly mastered the current mathematics, and, to the admiration of his professor, D. The most influential supporter of Brouwer’s intuitionism outside the Netherlands at the time was, for a number of years, Hermann Weyl. As, on Brouwer’s view, there is no determinant of mathematical truth outside the activity of thinking, a proposition only becomes true when the subject has experienced its truth by having carried out an appropriate mental construction ; similarly, a proposition only becomes false when the subject has experienced its falsehood by realizing that an appropriate mental construction is not possible.

The classical proofs are intuitionistically not acceptable because of the way luitsen depend on PEM; the intuitionistic proofs are classically not acceptable because they depend on reflection on the structure of mental proofs.
