| 21593 | In talking of future sea-fights, Aristotle rejects bivalence [Aristotle, by Williamson] |
| Full Idea: Unlike Aristotle, Stoics did not reject Bivalence for future contingencies; it is true or false that there will be a sea-fight tomorrow. | |
| From: report of Aristotle (On Interpretation [c.330 BCE], 19a31) by Timothy Williamson - Vagueness 1.2 | |
| A reaction: I'd never quite registered this simple account of the sea-fight. As Williamson emphasises, one should not lightly reject the principle of bivalence. Has Aristotle entered a slippery slope? Stoics disagreed with Aristotle. |
| 22154 | For Aristotle bivalence is a feature of reality [Aristotle, by Boulter] |
| Full Idea: For Aristotle the principle of bivalence is primarily a principle of metaphysics, not logic. It applies to entities in the real order first, and to propositions in the rational order second. | |
| From: report of Aristotle (Metaphysics [c.324 BCE]) by Stephen Boulter - Why Medieval Philosophy Matters 5 | |
| A reaction: This is because nothing is vague. Boulter says this is also the case with non-contradiction. I like this idea very much. I reject the Fregean picture of the autonomy of the rational order. Logic is powerful because it reflects reality. |
| 1701 | A prayer is a sentence which is neither true nor false [Aristotle] |
| Full Idea: A prayer is a sentence which is neither true nor false. | |
| From: Aristotle (On Interpretation [c.330 BCE], 17a01) |
| 12363 | 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. |
