5. Theory of Logic / D. Assumptions for Logic / 2. Excluded Middle
Everything is either asserted or denied truly [Aristotle]
     Full Idea: Of the fact that everything is either asserted or denied truly, we must believe that it is the case.
     From: Aristotle (Posterior Analytics [c.327 BCE], 71a14)
     A reaction: Presumably this means that every assertion which could possibly be asserted must come out as either true or false. This will have to include any assertions with vague objects or predicates, and any universal assertions, and negative assertions.
