I want to have a physical book that treats upon this for spergy OCD reasons. Only thing Ive found so far is Fundamentals of Mathematics by some Edwin (((Stein))) guy but it only goes so far as to briefly explain it on a single fucking paragraph.

Everywhere I look only refers to the same half a dozen webpages.
