Quick Summary

Felapton is a mnemonic term used in logic to represent a specific type of categorical syllogism. This syllogism has a particular structure regarding the quality and quantity of its propositions. In the Felapton mood, the major premise is a universal negative (E) proposition, the minor premise is a universal affirmative (A) proposition, and the conclusion is a particular negative (O) proposition.1

A syllogism is a deductive argument consisting of two premises and a conclusion. The validity of a syllogism lies in its logical form, ensuring that if the premises are true, the conclusion must also be true. Syllogistic logic, originating with Aristotle, is the formal analysis of such arguments.234
