Intuition, Intuitive Knowledge is synonymous with immediate knowledge.
Charles Peirce uses intuition in a purely technical sense to denote a knowledge determined not by another knowledge, but only by an object outside consciousness.
The conclusion of an argument is obviously knowledge determined by other knowledge, while the perception of a table is also obviously knowledge conditioned solely by an object external to consciousness (the table itself).
For this reason, the perception was intuition, an example of immediate (ie, immediate) knowledge.
In this sense, by denying that there is intuition, and by insisting that all our knowledge is mediated by all kinds of signs, Peirce opens the door to a completely semiotic approach to human knowledge.
