Originally published in 1966, this pivotal work of Mikel Dufrenne revises Kant's notion of a priori, a concept previously given insufficient attention by philosophers, to realize a rich understanding that finally does justice to one of Kant's most troubling cruxes.

MIKEL DUFRENNE (1910-1995) was a French philosopher and aesthetician. He is known as an author of existentialism, and is particularly noted for the work The Phenomenology of Aesthetic Experience. He encountered the work of Karl Jaspers while a prisoner of war, in a camp with Paul Ricoeur.
