The Art of LaTeX: Common mistakes and advice for typesetting proofs
I have a question: if what you have to write in order to create your beautiful and aesthetically pleasing proof, and thereby "establish your ethos and character" (presumably as a righteous and good), is an ugly and fragile instance of a poorly designed, inherently unreadable, archaic language that embodies none of the characteristics you are after, can the result really be "a work of art that combines both the precision and creativity of your logical thinking, as well as the elegance of a beautifully typeset writing?"
