He said he couldn't afford to buy books. The truth of the matter is that I was being kind. Since he failed to grasp this as well I'll explain that the reason I don't want his books is that his inability to grasp what I've been talking about, coupled with his demonstrated limitations in the realm of logic make his books uninteresting to me. I need to explain rudimentary logic to yet another person about yet another book like I need a toothache. As to limitations of knowledge, that would include not presuming to be superior when, in fact, he's failed to grasp the problem, not making iron-clad judgments when, in fact, he has misread and misrepresented what's been written creating a straw man, and recognizing that logic is a necessary part of that knowledge and that logic does NOT include ad hominem.
Logic is a great equalizer and no respecter of persons.
Physician, heal thyself.
