Darapti

The term "Darapti" refers to a specific mood within Aristotelian syllogistic logic. A syllogism is a deductive argument consisting of two premises and a conclusion, where the validity of the argument depends on its form rather than the truth of its premises. Aristotle's Prior Analytics is devoted to the theory of the syllogism, a method of inference where three terms are used: a major term, a minor term, and a middle term that appears in both premises but not the conclusion.12

Darapti is a syllogism in the third figure, characterized by two universal affirmative premises (A-form) and a particular affirmative conclusion (I-form). For example: "All M are P. All M are S. Therefore, Some S are P.". It's important to note that while Darapti is a valid mood, its conclusion is only true if the middle term (M) is assumed to exist.3
