“By declaring that everyone is equally an end, Kant ignores all personal differences, and therefore the fact of individuality as such. We are each an end in respect to those qualities only in which we are identical—namely, in that we are "rational beings." But this rational being is not a personal intelligence; it is a fiction, a bundle of mental faculties assumed a priori to exist, and then treated as if it were universally and equally applicable to all actually existing intelligences.”
