Categorical Propositions in Classical Logic/ Categorical Logic

Welcome to our lecture on categorical propositions! In this session, we'll explore the fundamental components of categorical propositions in logic. Categorical propositions are statements that assert or deny something about a given subject. They are divided into four types based on their quality (affirmative or negative) and quantity (universal or particular): universal affirmative (A), universal negative (E), particular affirmative (I), and particular negative (O). We'll discuss their structure, how they relate to each other, and their representation in the traditional Square of Opposition, providing a solid foundation for understanding logical arguments and syllogisms.
