Comment: like most such texts, it's an elaborate tissue of tautology (rhetoric)|rhetorical tautologies.  (''A large stone is greater in size than a small stone.  Large stones also differ from small stones by virtue of the fact that they occupy more space.  Large stones are more difficult to move than small ones.'')  Seems to be referenced to one author's books, which makes me suspect that this is |original research and may be intended to be promotional
