But if I apply these concepts to an object in general (in the transcendental sense),d without further determining whether this is an object of sensible or intellectual intuition, then limitations (which do not flow from this concept) immediately show up, which pervert all empirical use of them, and by that very means prove that the representation of an object as a thing in general is not merely insufficient but rather, without sensible determinations of it and inde pendent of an empirical condition, contradictory in itself, thus that one must either abstract from any object (in logic), or else, if one as sumes an object, then one must think it under conditions of sensible in tuition; thus the intelligible would require an entirely special intuition, which we do not have, and in the absence of this would be nothing for us, though on the contrary appearances also cannot be objects in them selves.
