If an animal does something, we call it instinct. If we do the same thing for the same reason, we call it intelligence.

Intellect is not going to be your home. It is a small instrument, to be used only for passing from instinct to intuition. So only the person who uses his intellect to go beyond it can be called intelligent. Intuition is existential. Instinct is natural. Intellect is just groping in the dark. The faster you move beyond intellect, the better; intellect can be a barrier to those who think nothing is beyond it. Intellect can be a beautiful passage for those who understand that there is certainly something beyond it.

In fact the opposition of instinct and reason is mainly illusory. Instinct, intuition, or insight is what first leads to the beliefs which subsequent reason confirms or confutes; but the confirmation, where it is possible, consists, in the last analysis, of agreement with other beliefs no less instinctive. Reason is a harmonising, controlling force rather than a creative one. Even in the most purely logical realms, it is insight that first arrives at what is new.

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.

Intelligence is the ability to solve problems. Consciousness is the ability to feel things such as pain, joy, love, and anger. We tend to confuse the two because in humans and other mammals intelligence goes hand in hand with consciousness. Mammals solve most problems by feeling things. Computers, however, solve problems in a very different way.

Intelligence is quickness to apprehend as distinct from ability, which is capacity to act wisely on the thing apprehended.

Instinct is untaught ability.

The intuition is not a welling forth of love to people and, therefore, an understanding of them. Much that is called the intuition is recognition of similarities and the possession of a clear analytical mind. Intelligent people who have lived in the world for some time and who have experienced much and who have contacted many other people can usually sum up with facility the problems and dispositions of others, provided they are interested. This they must not, however, confound with the intuition.

Intelligence starts ordinarily from the immobile, and reconstructs movement as best it can with immobilities in juxtaposition. Intuition starts from movement, posits it, or rather perceives it as reality itself, and sees in immobility only an abstract moment, a snapshot taken by our mind, of a mobility. Intelligence ordinarily concerns itself with things, meaning by that, with the static, and makes of change an accident which is supposedly superadded. For intuition the essential is change: as for the thing, as intelligence understands it, it is a cutting which has been made out of the becoming and set up by our mind as a substitute for the whole. Thought ordinarily pictures to itself the new as a new arrangement of pre-existing elements; nothing is ever lost for it, nothing is ever created. Intuition, bound up to a duration which is growth, perceives in it an uninterrupted continuity of unforeseeable novelty; it sees, it knows that the mind draws from itself more than it has, that spirituality consists in just that, and that reality, impregnated with spirit, is creation. The habitual labor of thought is easy and can be prolonged at will. Intuition is arduous and cannot last.

Intuition is a method of feeling one's way intellectually into the inner heart of a thing to locate what is unique and inexpressible in it.

Intuition is a distinct form of experience. Intuition is of a self-certifying character (svatassiddha). It is sufficient and complete. It is self-established (svatasiddha), self-evidencing (svāsaṃvedya), and self-luminous (svayam-prakāsa). Intuition entails pure comprehension, entire significance, complete validity. It is both truth-filled and truth-bearing Intuition is its own cause and its own explanation. It is sovereign. Intuition is a positive feeling of calm and confidence, joy and strength. Intuition is profoundly satisfying . It is peace, power and joy.

Intuition! What's that? Define it!" "Easily. 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 (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.
