Chapter 13: More on Modal Assertions

Show Summary Details

Preview

The discussion of modal assertions is now broadened to include the inferences, which may be drawn between them. The Modal Square of Opposition is set out, problems with the initial formulation are revealed and dealt with by ensuring that a single sense of possibility occurs throughout (possibility is implied by necessity, not excluded by it). In a final comment, Aristotle explains the importance of these assertions: possibility and necessity are the origins of the being, and not being of everything.

Keywords: Aristotle; assertion; De Interpretatione; inference; modal; modality; necessity; possibility; square of opposition
