Appendix

(1) Whoever grasps only the perceptual contents of things and takes these for reality, is a naïve realist, and he does not realize that, strictly, he ought to regard these perceptual contents as existing only as long as he is looking at the things, so that he ought to think of the things before him as intermittent. As soon, however, as it becomes clear to him that reality is present only in the percepts that are permeated by thought, he will see that the perceptual contents which appear as intermittent reveal themselves as continuous as soon as they are permeated with the results of thinking. Hence we must count as continuous the perceptual content that has been grasped through the experience of thinking, of which only that part that is merely perceived could be regarded as intermittent, if—which is not the case—it were real.
