INNER SENSE

[A33/B49] Inner sense is the faculty through which we intuit ourselves and our own inner states. "It cannot be a determination of outer appearances; it has to do neither with shape nor position, but with the relation of representations in our inner state". Namely, it has to do with the temporal relations of our representations; for "time is nothing but the form of inner space". As such, time "is the formal a priori condition of all appearances whatsoever" (whereas space in an a priori condition only of outer appearances).
