Constructive Mathematics
A bibliography of constructive mathematics
Compiled by: Douglas S. Bridges
The following is a brief list of references that might interest people who are new to constructive mathematics. First, we have two websites:

Constructive Mathematics—Stanford Encyclopedia of Philosophy
Constructive mathematics is distinguished from its traditional counterpart, classical mathematics, by the strict interpretation of the phrase “there exists” as “we can construct”. In order to work constructively, we need to reinterpret not only the existential quantifier but all the logical connectives and quantifiers as instructions on how to construct a proof of the statement involving these logical expressions....

Luitzen Egbertus Jan Brouwer—Stanford Encyclopedia of Philosophy
Dutch mathematician and philosopher who lived from 1881 to 1966. He is traditionally referred to as ‘L.E.J. Brouwer’, with full initials, but was called ‘Bertus’ by his friends.
In classical mathematics, he founded modern topology by establishing, for example, the topological invariance of dimension and the fixpoint theorem. He also gave the first correct definition of dimension.
In philosophy, his brainchild is intuitionism, a revisionist foundation of mathematics. Intuitionism views mathematics as a free activity of the mind, independent of any language or Platonic realm of objects, and therefore bases mathematics on a philosophy of mind. The implications are twofold. First, it leads to a form of constructive mathematics, in which large parts of classical mathematics are rejected. Second, the reliance on a philosophy of mind introduces features that are absent from classical mathematics as well as from other forms of constructive mathematics: unlike those, intuitionistic mathematics is not a proper part of classical mathematics...
