Logic, according to Gottlob
Frege, the founder of modern symbolic logic, is the
science of thought. By this, he did not mean that logic studies how we actually
do think -- psychology does that. Rather, he meant logic is the most general
science, the study of rules of correct thinking that govern every discipline.
No matter what you're thinking about, you have to obey the laws of logic if you
want to avoid error. Following Frege,
this course studies rules of formal deductive reasoning. We will study
validity and invalidity of argument forms, consistency, and translation between
the formal system and ordinary language. We will study truth-functional logic
(the logic of sentences related by 'and', 'or', 'not', 'if...then', and 'if and
only if') and predicate logic (the logic of sentences containing terms such as
'all', 'every', and 'some').
