NOTE: the program lets you drop the outermost parentheses on formulas with a binary main connective, e.g. P>(Q&R) rather than (P>(Q&R)).

Natural deduction is a method of proving the logical validity of inferences, which, unlike truth tables or truth-value analysis, resembles the way we think. It consists in constructing proofs that certain premises logically imply a certain conclusion by using previously accepted simple inference schemes or equivalence schemes.

3. Natural Deduction for Propositional Logic¶. Reflecting on the arguments in the previous chapter, we see that, intuitively speaking, some inferences are valid and some are not. For example, if, in a chain of reasoning, we had established “ \(A\) and \(B\),” it would seem perfectly reasonable to conclude \(B\).If we had established \(A\), \(B\), and “If \(A\) and \(B\) then \(C ...
