Abstract: The erotics of art emphasizes the form and therefore sensibility, it's a loud shout to the ear of sensibility. There are some likeness between erotics of art and aesthetical liberation of Eros of H.Marcuse. As a base of life, eros finally walks to an end with aesthetics, that's freedom.Susan sontag claimed that the erotics of art from against interpretation is intersubjectivity and indivisibility of body and mind.The base of erotics is eros which is fundamentality life.With the eros,art goes to freedom finally. Uudoubtedly, this proposition of Susan is instructive to the criticism and theory of art in China for that the erotic of art means form and sensibility of art.

Key words: Susan sontag, erotics of art, Eros, bodysubject
