Appendix

Firstly, one remains at the naïve point of view, which regards perceived phenomena as real things existing outside human consciousness. This implies a lack of critical knowledge. One fails to realize that with the content of one's consciousness one remains, after all, only within one's own consciousness. One fails to perceive that one is dealing, not with a “table-in-itself”, but only with an object in one's own consciousness. Whoever remains at this point of view, or for whatever reason returns to it, is a naïve realist. But this whole position is untenable for it fails to recognize that consciousness has no other objects than its own contents.
