This document discusses the case for teaching syllogistic logic to philosophy students. It contains examples of valid syllogistic arguments using terms like "All," "Some," and "No." It also discusses the inability to demonstrate the existence of God through deductive reasoning alone, as the premises would need to be certain a priori propositions, but the existence of God is not a tautology or logical certainty. It provides examples of different types of categorical propositions like contradictories, contraries, and sub-contraries to illustrate logical concepts.
