The square of opposition is a diagram representing the relations between four propositions or four concepts.
The origin of the square can be traced back to Aristotle (nonfiction) making the distinction between two oppositions: contradiction and contrariety, although Aristotle did not draw any diagram.
Early diagrams were drawn several centuries later by Apuleius and Boethius.
