Twenty quotes, four arguments, set against photos taken by Joe Pineda in Versailles across a single afternoon. Each quote receives an informal premise, a formal rendering, and a lesson. You do not need to read the symbols to read the book. Each formula only says, more carefully, what the sentence above it already said: ∀x is for every x, → is if this, then that, ¬ is not. You don’t have to read them in order. But the order means something.
