Chabot College/Las Positas College January 1994 Course Outline for Mathematics 12A LOGIC I Catalog Description: 12A - Logic I 3 units Introduction to formal deductive logic with emphasis on developing the basic concepts of modern symbolic logic; includes the concept of deductive validity, relation of ordinary languages to symbolic logic, distinction between inductive validity and deductive logic, relation of truth to validity and the uses of truth tables, role of logic in the disciplines of mathematics, philosophy and sciences, rules of inference for propositional logic and first order predicate logic. 3 hours. Expected Outcomes for Students: Upon completion of the course, the student should be able to: 1. operationally define the technical terms of sentential (propositional) logic, including such terms as: proposition, formula of sentential logic, sentential connectives, deductive argument, premise of an argument, conclusion of an argument, validity, invalidity, consistency, inconsistency, disjunction, conjunction, conditional (implication) bi-conditional (equivalence), and negation; 2. translate propositions stated in ordinary language into logic formulas, using the notation of sentential logic developed in this course; 3. determine the validity or invalidity of deductive arguments which can be stated in the formulae of sentential logic; 4. determine the consistency or inconsistency of a given set of premises which are able to be represented in the formulae of sentential logic; 5. prove the validity of a valid argument of the sentential logic, using the rules of validity developed in this course, and including the rules: tautological implication, substitution, conditional proof, and reductio ad absurdum; 6. prove the invalidity of an invalid argument of sentential logic, using the method of assigning truth values; 7. demonstrate the consistency of a consistent set of premises using the method of assigning truth values; 8. demonstrate the inconsistency of an inconsistent set of premises, using the method of reductio ad absurdum; 9. translate ordinary language propositions into the notation of the first order predicate logic using universal and existential quantifiers, and the symbolic notation developed in this course; 10. prove the logical validity of arguments which can be represented in terms of universally general formulae of first order predicate logic, and involving only the rules Universal Specification and Universal Generalization.
