The concept of intuition is more often used in philosophical theorizing than is the concept of observation in scientific theorizing (proportionately). One reason is that there is (proportionately) more ostensible conflict of philosophical intuitions than there is ostensible conflict of scientific observations. So much for the use of a concept of intuition in philosophical theorizing.

Through our perceptual systems, we represent our surroundings, aiming to do so accurately, where the aiming is functional or teleological, rather than intentional. And the same goes for our functional beliefs. Through our judgments, however, we do intentionally, even consciously, attempt to get it right.

It is possible to produce something that is grammatical either by chance or under the supervision of another. To be proficient in grammar, then, one must both produce what is grammatical and produce it grammatically, that is, in accord with knowledge of grammar in oneself.

Knowledge in my view is a form of action. It involves endeavors to get it right, and more broadly it concerns aimings, which can be functional rather than intentional.

Animal knowledge is metaphysically constituted by apt belief, by belief whose correctness manifests the believer's epistemic competence, a relevant disposition to get it right on the matter at hand when one tries to do so.

In order to qualify as a judgment, an affirmation must aim at getting it right aptly, through competence, and not just through a lucky guess.

Intuitive seeming is in my view an attraction to assent based on nothing more than understanding of the content that upon consideration attracts one's assent. But such understanding-based attraction can differ dramatically in epistemic quality. Some such attractions represent nothing more than superstition or bias absorbed from the culture, sans ratiocination.
