Intuition

Intuition is an immediate form of knowledge in which the knower is directly acquainted with the object of knowledge. Intuition differs from all forms of mediated knowledge, which generally involve conceptualizing the object of knowledge by means of rational/analytical thought processes (and, hence, placing a mediating idea or concept between the knower and the known).

Some philosophers consider human experience of raw empirical data (sometimes called "qualia") to be intuitive. For example, when a person sees a patch of yellow, that person is directly acquainted with the yellowness of the object, even if he or she has no name or concept for yellowness.

Intuition differs from opinion since intuition is a way of experiencing objects, while opinion is based on that experience. Intuition also differs from instinct, which does not necessarily have the experiential element at all. A person who has an intuitive basis for an opinion probably cannot immediately fully explain why he or she holds that view. However, a person may later rationalize an intuition by developing a chain of logic to demonstrate more structurally why the intuition is valid.

In popular understanding, intuition is one source of common sense and it may also help in induction to gain empirical knowledge.
