Symbolic Logic

An Introduction to Symbolic Logic Copyright 2006-09 by Terence Parsons all rights reserved Copyrighted material Introduction -- 2 To the Instructor: The system of Logic used here is essentially that of Kalish, Montague and Mar, Harcourt Brace Jovanovich, 1992. The principle difference is that written justifications are required for boxing and canceling: 'dd' for a direct derivation, 'id' for an indirect derivation, etc. This text was written to be used along with the UCLA Logic2K software program, but that program is never mentioned, and the text can be used independently (although you would want to supplement the exercises).

6 conditional derivations 7 indirect derivations 8 subderivations 9 shortcuts 10 strategy hints for derivations 11 theorems 12 using previously proved theorems in derivations chapter two sentential logic with 'and', 'or', if-and-only-if' 1 symbolic notation 2 english equivalents of the connectives 3 complex sentences 4 rules 5 some derivations ...

the difference between these two forms by saying that the conditional is the con-templated relation, while the implication is the asserted relation. We will discuss this distinction in the Section 1.2, where we formally study relations between state-ments. The importance and soundness of the conditional form P!Qwill become clearer then.
