This also illustrates that automated deduction in propositional logic and automated deduction in first-order logic have completely di erent emphases, with respect.

Completeness of First-order Predicate Logic Theorem There exists a computer program that outputs exactly the tautologies of ﬁrst-order predicate logic. There are many distinct types of deduction systems that can be used to imple-ment such a program: Hilbert-style systems Natural deduction Sequent calculus Tableaux method Resolution

Consider the case of the magic rock that keeps tigers away (from the Simpsons, paraphrased): Lisa: By your logic I could claim that this rock keeps tigers away. Homer: Oh, how does it work? First-Order Logic At the end of the last lecture, I talked about doing deduction and propositional logic in the natural deduction, high-school geometry style, and then I promised you that we would look at resolution, which is a propositional-logic proof system used by computers. and First Order Logic Propositional Logic First Order Logic Deduction Theorem Theorem Given a set of formulas fF 1; ;F n gand a formula G, (F 1 ^^ F n) j= G if and only if j= (F 1 ^^ F n) !G.

Sketch of proof.)For each interpretation I in which F 1 ^^ F n is true G is true, I j= (F 1 ^^ F n) !G , however for every interpretation I 0in which F 1 Deduction theorems exist for both propositional logic and first-order logic. The deduction theorem is an important tool in Hilbert-style deduction systems because it permits one to write more comprehensible and usually much shorter proofs than would be possible without it.

P. Dasgupta, Department of Computer Science & Engineering, I.I.T,kharagpur. For More details on NPTEL visi Predicate logic was created by Gottlob Frege (Frege (1879)) and first-order (predicate) logic was first singled out by Charles Sanders Peirce and Ernst Schröder in the late 1800s (cf. van Heijenoort (1967)), and, following their lead, by Leopold Löwenheim (Löwenheim (1915)) and Thoralf Skolem (Skolem (1920), (1922)). First Order Logic Quantification over values of base type Terms and formulas are syntactically distinct Higher Order Logic Quantification over functions and predicates Consistency by typing Formula = term of type bool Predicate = function with codomain bool λ + a few types and constants Natural Deduction Two kinds of rules for each logical operator Natural deduction for predicate logic Readings: Section 2.3. In this module, we will extend our previous system of natural deduction for propositional logic, to be able to deal with predicate logic. The main things we have to deal with are equality, and the two quantiﬁers (existential and universal).

First-order Natural Deduction: Warning: a common mistake How about replacing the rule (9E) with the following, simpler one? (9E0) 9xA(x) A[c=x] where c is a new constant symbol. Though simple and looking natural, this rule isnot valid! Using it, one can derive the invalid implication 9xA(x) ! A[c=x].
