Natural Deduction. Welcome to Natural Deductive Logic, which is a rigorous introduction to Propositional and Predicate Logic with Metatheory. These videos will cover everything you need to know in an introductory logic course, as well as touch on some topics you would encounter in an intermediate logic course.

A Natural Deduction proof in PC is a sequence of wffs beginning with one or more wffs as premises; fresh premises may be added at any point in the course of a proof. New wffs are generated by applying "rules" to any wff or a group of wffs that have already occurred in the sequence.

The deduction theorem helps. It assures us that, if we have a proof of a conclusion form premises, there is a proof of the corresponding implication. However, that assurance is not itself a proof. Natural deduction cures this deficiency by through the use of conditional proofs.

Natural Deduction Testing whether a proposition is a tautology by testing every possible truth assignment is expensive—there are exponentially many. We need a deductive system , which will allow us to construct proofs of tautologies in a step-by-step fashion. The concept of natural deduction follows a truly natural progression, establishing the relationship between a noteworthy systematization and the interpretation of logical signs.

We need a deductive system , which will allow us to construct proofs of tautologies in a step-by-step fashion. The concept of natural deduction follows a truly natural progression, establishing the relationship between a noteworthy systematization and the interpretation of logical signs. As this survey explains, the deduction's principles allow it to proceed in a direct fashion — a manner that permits every natural deduction's transformation into the equivalent of normal form theorem. Natural deduction shows how the conclusion of a valid argument can be derived step by step from its premises. If we know that an argument is valid, then we can draw its conclusion from its premises using common argument forms and equivalence rules.
