But that it really must can clearly shown, one lets space count a a mere pure form of the appearances of outer sense, from the fact that time, although is not itself an object of outer intuition at all, cannot be made representable to us except under the image of a line, insofar as we draw it, without which sort of presentation we could not know the unity of its measure at all, or likewise from the fact that we must always derive the determination of the length of time or also of the positions in time for all inner perceptions from that which presents external things to us as alterable; hence we must order the determinations of inner sense as appearances in time in just the same way as we order those of outer sense in space; hence if we admit about the latter that we cognize objectsC by their means only insofar as we are externally affected, then we must also concede that through inner sense we intuit ourselves only as we are internally affected by our selves,.e., as far as inner intuition is concerned we cognize our own subject only as appearance but not in ac cordance with what it is in itself.
