If we understand thereby only objects of a non sensible intuition, of which our categories are cer tainly not valid, and of which we can therefore never have any cognition at all (neither intuition nor concept), then noumena in this merely negative sense must of course be allowed: for they would then not say anything but that our manner of intuition does not pertain to all things, but only to objects of our senses, consequently that their objective va lidity is bounded, and room thus remains for some other sort of intuition and therefore also for things as its objects.c
