Idealistic identity and dialectical Mimesis in Adorno's negative aesthetics

Adorno points out the philosophical transcendence of art but - against Hegel-he does it on the base of the convergence of art and philosophy. That convergence is founded on the dialectic of mimesis discovered in the aesthetic experience. Adorno incorporates to philosophy the aesthetic element of mimesis, which is what permits philosophical reason, in the first place, to surpass the identity imposed by hegelian idealism; and in the second place, to constitute itself in dialectic to think what cannot be thought, that is, the concrete.
