Emphasis mine.
> Would you say Calculus textbooks are for people who want others to think for them? Do Real Men take a short primer on mathematical logic and the axioms of ZFC set theory, and go derive Calculus for themselves?
My response was argumentum ad absurdum, so I gain nothing from defending the position, but still:
Walter Rudin's Principles Of Mathematical Analysis would be a terrible book if it tried to relate the matter's purpose at every step. Nobody expects a mathematical textbook to do that.
In fact Principles Of Mathematical Analysis is a great book for being extremely concise and containing just what is necessary for a reasonably intelligent reader to understand the material.
To be more clear, I don't believe that your explanation could possibly be a good reason for these stories being included in a self help book, but without precluding they may serve another purpose.
