Chapter Summary

Robert Kilwardby pursues a program of supplementing Aristotle's text in ways designed to enhance its credibility and to display its systematicity. He distinguishes propositions and statements, identifies types of proposition not mentioned by Aristotle, and provides semantical interpretations of different proposition-types. Given that Aristotle's interest in the Prior Analytics is in propositions as premises and conclusions of syllogisms, and that for this purpose the most essential difference is between affirmative and negative. Contingency-propositions may or may not ampliate their subjects. Assertoric propositions may be subject to temporal restrictions or may be unrestricted. Assertorics may be either as-of-now or unrestricted. Unrestricted assertorics may be either necessary or natural. A non-necessary contingency-proposition states a pair of one-way possibilities.
