A → philosophy of → mathematics that was introduced by the
Dutch mathematician L.E.J. Brouwer (1881-1966). Intuitionism is based on the idea that mathematics is a creation of the mind. The truth of a mathematical statement can only be conceived via a mental construction that proves it to be true, and the communication between mathematicians only serves as a means to create the same mental process in different minds (Stanford Encyclopedia of Philosophy).
