Mood

Definition

In the context of categorical syllogisms, mood refers to the specific form of a syllogism based on the types of categorical propositions it contains. It is determined by the quality (affirmative or negative) and quantity (universal or particular) of each proposition in the syllogism, ultimately influencing the validity of the argument.
