By intuition I mean, not the wavering assurance of the senses, or the deceitful judgment of a misconstructed imagination, but a conception, formed by unclouded mental attention, so easy and distinct as to leave no room for doubt in regard to the thing we are understanding.

The very word intuition has to be understood. You know the word tuition — tuition comes from outside, somebody teaches you, the tutor. Intuition means something that arises within your being; it is your potential, that’s why it is called intuition. Wisdom is never borrowed, and that which is borrowed is never wisdom. Unless you have your own wisdom, your own vision, your own clarity, your own eyes to see, you will not be able to understand the mystery of existence.

Intuition is the art, peculiar to the human mind, of working out the correct answer from data that is, in itself, incomplete or even, perhaps, misleading.

Intuition is not a single way of knowing - it's our ability to hold space for uncertainty and our willingness to trust the many ways we've developed knowledge and insight, including instinct, experience, faith
and reason.

INTUITION (L. intueri, ‘to look at or into’). I regard intuition as a basic psychological function (q.v.). It is the function that mediates perceptions in an unconscious way. Everything, whether outer or inner objects or their relationships, can be the focus of this perception. The peculiarity of intuition is that it is neither sense perception, nor feeling, nor intellectual inference, although it may also appear in these forms. In intuition a content presents itself whole and complete, without our being able to explain or discover how this content came into existence. Intuition is a kind of instinctive apprehension, no matter of what contents. Like sensation (q.v.), it is an irrational (q.v.) function of perception. As with sensation, its contents have the character of being “given,” in contrast to the “derived” or “produced” character of thinking and feeling (qq.v.) contents. Intuitive knowledge possesses an intrinsic certainty and conviction, which enabled Spinoza (and Bergson) to uphold the scientia intuitiva as the highest form of knowledge. Intuition shares this quality with sensation (q.v.), whose certainty rests on its physical foundation. The certainty of intuition rests equally on a definite state of psychic “alertness” of whose origin the subject is unconscious.

Intuition is unconscious accumulated experience informing judgement in real time.

Intuition is like reading a word without having to spell it out. A child can't do that because it has had so little experience. A grown-up person knows the word because they've seen it often before.

Intelligence is composed mostly of imagination, insight, things that have nothing to do with reason.

The intuition we refer to then bears above all upon internal duration. It grasps a succession which is not juxtaposition, a growth from within, the uninterrupted prolongation of the past into a present which is already blending into the future. It is the direct vision of the mind by the mind, — nothing intervening, no refraction through the prism, one of whose facets is space and another, language. Instead of states contiguous to states, which become words in juxtaposition to words, we have here the indivisible and therefore substantial continuity of the flow of the inner life. Intuition, then, signifies first of all consciousness, but immediate consciousness, a vision which is scarcely distinguishable from the object seen, a knowledge which is contact and even coincidence. —

Intuition is really a sudden immersion of the soul into the universal current of life.

Intuition (is) perception via the unconscious

Intuition is seeing the solution.....its emotion and intellect going together.

The very essence of instinct is that it's followed independently of reason.

A new idea comes suddenly and in a rather intuitive way, but intuition is nothing but the outcome of earlier intellectual experience.
