THE SQUARE OF OPPOSITION 2 The Square of Opposition Developed by Aristotle in the fourth century B.C.E, categorical logic, also known as Aristotelian or traditional logic, is used to clarify and analyze deductive arguments. This form of logic is used to break down claims and put them in categories and translate them into simpler standard-form claims. While there are many ways to categorized claims, there are four main types of sentences that can be translated into statements called A, E, I, O claims. From there these standard-form claims can be inputted into the square of opposition to help find their corresponding claim. Categorical logic is based on the relations of inclusion and exclusion among four basic kinds of claims. There are many ways to categorize claims but there are four main standard-form types of claims. these four types of claims are referred to as the universal affirmative (A) statement, the universal negative (E) statement, the particular affirmative (I) statement, and lastly the particular negative (O) statement. Statements in the A category are in the form of “All ___ are ___.” For E statements the claim looks like “No ___ are ___.” When putting I statements into a category, their claims follow the form “Some ___ are ___.” Lastly, statements in the O category are in the form of “Some ___ are not ___.” Words that go inside of the blank spaces are called terms, and these terms can only be nouns or noun phrases.
