Kant is well known as the philosopher who spent his life hunting for a prioris, philosophically identifiable characteristics of the make-up of human beings. These characteristics are species-universal, and are necessary presuppositions of the possibility of the success of various kinds of cognitive and cultural strategies. Kant bagged some big game. Space, time and the categories are a priori conditions of the possibility of human cognition. God, freedom and immortality are a priori conditions of the possibility of morality. The sensus communis is the a priori condition of the possibility of the universalization of judgments of taste. The hard-won trophies are presuppositions of possibilities. Once they were thought to be properties of a universe well ordered by a substantive god. No longer. Now we must look upon them as entrenched contributions of what it is to be human, as preconditions of human potentialities.
