Intuition is an important way to understand phenomenology.Generally,Husserl's breakthrough in Logical Investiga-tion is that categories can be intuitional as much as something perceptible;thereout Husserl has initiated the theory of intuition,which is"the principle of all principles"that he calls in Idea I,and which claims the exhaustive evident in epistemology.With the Husserl's theory of intuition,phenomenology breaks the settings which are dogmatism from rationalism and skepticism from empiricism.Therefore,the way we choose to interpret Husserl's theory of intuition is significant.Exactly as a result of the differ-ent interpretations of the theory of intuition,subsequent phenomenologists such as Heidegger,Derrida and Marion,are presen-ting a diverse theoretical landscape in their philosophical reflections.Though categorial intuition is an analogue to perceptual in-tuition,categorial intuition actually has the following implications:category as"objectivity"can not only be intuitional,but also contain a new mode of intuition:sensuous intuition.There is essentially difference between sensuous intuition and perceptual in-tuition;compared with perceptual intuition,sensuous intuition is only a kind of"seeming intuition".Eventually Marion follows the train of thought from Heidegger,and names"seeming intuition"as givenness.
