This is one of the best-written books ever! Most non-fiction works strive (knowingly or not) to reach such a fine form. Words are massaged into terms, sentences into propositions, and certain paragraphs into arguments. This work is the purest form of that, a true paragon with enviable succinctness. Even if you're not into math, try picking up a copy of Euclid's Elements to see how articulate thoughts _can_ be.
