In the philosophy of Immanuel Kant, intuition is one of the basic cognitive faculties, equivalent to what might loosely be called perception.

Intuitionistic logics are a class of logics, devised and advanced by Arend Heyting and Luitzen Egbertus Jan Brouwer and more recently by Michael Dummett, to accommodate intuitionism about mathematics (as well as anti-realism more generally). These logics are characterized by rejecting the law of excluded middle: as a consequence they do not in general accept rules such as disjunctive syllogism and reductio ad absurdum.
