It could be objected that if the pathway of limitation exists on the level of the unlimited without limitations and boundaries, this cannot be said to be the pathway of limitation. This objection may be answered if we distinguish between the kind of concept that includes another concept in the sense of affirming or maintaining its existence, and a different kind of concept that includes or involves another concept only in the sense that it is its very opposite and its negation. An example of the latter is death. The idea of death has no meaning without life, which death brings to an end. Death thus includes life in the sense that it is the negation of life, not that it sustains life. This is not so in the case of life, which does not include death at all.
