I. The Three Intuitions
IA. Eidetic Intuitions
Intuition is supposed to be a form of direct access. Yet, direct access to what? Does it access directly “intuitions” (abstract objects, akin to numbers or properties – see “Bestowed Existence”)? Are intuitions the objects of the mental act of Intuition? Perhaps intuition is the mind’s way of interacting directly with Platonic ideals or Phenomenological “essences”? By “directly” I mean without the intellectual mediation of a manipulated symbol system, and without the benefits of inference, observation, experience, or reason.
Kant thought that both (Euclidean) space and time are intuited. In other words, he thought that the senses interact with our (transcendental) intuitions to produce synthetic a-priori knowledge. The raw data obtained by our senses -our sensa or sensory experience – presuppose intuition. One could argue that intuition is independent of our senses. Thus, these intuitions (call them “eidetic intuitions”) would not be the result of sensory data, or of calculation, or of the processing and manipulation of same. Kant’s “Erscheiung” (“phenomenon”, or “appearance” of an object to the senses) is actually a kind of sense-intuition later processed by the categories of substance and cause. As opposed to the phenomenon, the “nuomenon” (thing in itself) is not subject to these categories.
Descartes’ “I (think therefore I) am” is an immediate and indubitable innate intuition from which his metaphysical system is derived. Descartes’ work in this respect is reminiscent of Gnosticism in which the intuition of the mystery of the self leads to revelation.
Bergson described a kind of instinctual empathic intuition which penetrates objects and persons, identifies with them and, in this way, derives knowledge about the absolutes – “duration” (the essence of all living things) and “
