What is the difference between Philosophy 279, Logic I, and Philosophy 377, Elementary Formal Logic?
A. (a) The difference between Philosophy 275 and Philosophy 279: Logic deals with the structure of arguments, good and bad. Philosophy 279 concentrates more on the formal and symbolic aspects of arguments. In it students will study sentential logic (the branch of logic that covers arguments involving whole sentences) and quantificational logic (the branch of logic that deals with the formal structure of arguments involving sentence content). In addition Philosophy 279/377 considers the metatheory of logic: the results we gain when we consider theorems about systems as a whole, and not just results within the system. Topics that may be treated include questions about the consistency and completeness of various logical systems. Philosophy 275 on the other hand restricts its treatment of the formal side of logic to sentential logic, without metatheory, and offers as well an introduction to informal logic (sometimes called critical thinking): the treatment of arguments good and bad as they
