There might be a problem with textbooks. What I see is that either
they are too technical for a broader audience and deal with
specialists' material or cover the question very shallowly (yes, even
yours, pp. 205-208 in Logic, Induction and Sets, no offense meant). I
said "what I see" - is there a 20-30 pages introduction to the subject
that is readable for the non-specialist?
