WebWhen a proof is normalized, its size may grow exponentially (see, for example, Boolos 1984, Fitting 1996, D’Agostino 1999). What is important in normal proofs is that, due to their conceptual simplicity, they provide a proof theoretical justification of deduction and a new way of understanding the meaning of logical constants. 10.

WebThe patterns which proofs follow are complicated, and there are a lot of them. You can't expect to do proofs by following rules, memorizing formulas, or looking at a few examples in a book. For this reason, I'll start by discussing logic proofs. Since they are more highly patterned than most proofs, they are a good place to start.
