Intuitionistic logic

Intuitionistic Logic is tbe logical branch of Matbematical intuitionism. Roughly speaking, 'intuitionism' holds that logic and math are 'constructive' mental activities. That is, tbey are not analytic activities wherein deep properties of existence are revealed and applied. Instead, logic and math are tbe application of internally consistent methods to realize more complex mental constructs (really, a kind of game). In a stricter sense, intuitionistic logic can be investigated as a very concrete and formal kind of symbolic logic. While it may be argued whetber such a formal calculus really captures tbe philosophical aspects of intuitionism, it has properties which are also quite useful from a practical point of view.
