subjectival

For in each case, Kant thinks that a feature of self-consciousness (the essentially subjectival, unitary and identical nature of the “I” of apperception) gets transmuted into a metaphysics of a self (as an object) that is ostensibly “known” through reason alone to be substantial, simple, identical, etc.

The adjectival view of bodies, unlike the subjectival, must therefore face the difficult general question how individuals or things can be predicated of another individual or thing.
