| In common usage, intuitions lead us to believe things without being able to articulate evidence or reasons for those beliefs. In philosophy, the [[epistemology|epistemic]] credentials of various types of intuition may be investigated, or "intuition" may be used as a technical term to single out a particular type of mental state or propositional attitude. Intuitions are distinguished from [[beliefs]], since we can hold beliefs which are not intuitive, or have intuitions for propositions that we know to be false. | | In common usage, intuitions lead us to believe things without being able to articulate evidence or reasons for those beliefs.

| "Intuitionism" is a position advanced in [[philosophy of mathematics]] derived from Kant's claim that all [[mathematics|mathematical knowledge]] is knowledge of the pure forms of the intuition - that is, intuition that is not empirical (''Prolegomena, p.7''). Intuitistic logic was devised by Arend Heyting to accommodate this position (and has been adopted by other forms of [constructivism in general). It is characterized by rejecting the [[law of excluded middle]]: as a consequence it does not in general accept rules such as double negation elimination and the use of [[reductio ad absurdum]] to prove the existence of something. | | "Intuitionism" is a position advanced in [[philosophy of mathematics]] derived from Kant's claim that all [[mathematics|mathematical knowledge]] is knowledge of the pure forms of the intuition - that is, intuition that is not empirical (''Prolegomena, p.7'').
