Art is a new form of modem philosophy which attempts to get rid of the old epistemology and plunge itself into individual participation in the grand scheme of things. Merleau-Ponty's theories on phenomenology are extremely relevant in tackling the philosophical dilemmas brought forth by Descartes. He has demonstrated how nature and consciousness cannot be separated, realizing how absolutely vital the physical body actually is. Heidegger's "Dasien" is too abstract while Merleau-Ponty's "body" is easier to recognize. Merleau-ponty insists that it's "the body" not the mind that perceives and expresses itself. This is the foundation of perception theory in ontology of art. The exchange system of "visual/body/world" is the real situation in art creation and transubstantiation is a mystery. About the reality of art, Merleau-Ponty raises "chaism", "intertwining", "entrlaces", "réversibilité", "ambiguité", and silence is the essence.
The "body" theory of Merleau-Ponty is aesthetics has evolved considerably from that of traditional metaphysics and psychology. It is the author's opinion that up to now, Merleau-ponty's "body" theory has successfully enveloped essence of art.
