The remark of Alexander of Aphrodisias on Aristotle's Prior Analytics 1.8-22 is the most historical observation, through the 'greatest' commentator, at the chapters of the Prior Analytics during which Aristotle invented modal common sense - the good judgment of propositions approximately what's helpful or contingent (possible). during this quantity, which covers chapters 1.8-13, Alexander of Aphrodisias reaches the bankruptcy during which Aristotle discusses the inspiration of contingency. additionally integrated during this quantity is Alexander's observation on that a part of Prior Analytics 1.17 and is the reason the conversion of contingent propositions (the remainder of 1.17 is integrated within the moment quantity of Mueller's translation).
Aristotle additionally invented the syllogism, a mode of argument related to premises and a end. Modal propositions could be deployed in syllogism, and within the chapters integrated during this quantity Aristotle discusses syllogisms inclusive of helpful propositions in addition to the extra arguable ones containing one worthwhile and one non-modal premiss. The dialogue of syllogisms containing contingent propositions is reserved for quantity 2.

Sample text

Aristotle has little to say about the third case. He remarks that EE-conversionc fails and OO-conversionc works, but defers discussion until chapter 17: But those things which are said to be contingent inasmuch as they are for the most part and by nature – and this is the way we specify contingency – will not be similar in the case of negative conversions. Rather a universal negative proposition does not convert, and the particular does convert. This will be evident when we discuss contingency.

Immediately after this passage at 226,32-227,9 Alexander gives the correct explanation of the illegitimacy of the inference. Summary Symbols and rules Our symbols are all explained in the introduction. We here give brief explications of the less usual ones. NEC(P) is read ‘It is necessary that P’. CON(P) is read ‘It is contingent that P’. In the introduction we have tried to ‘unfold’ our understanding of the relevant notion of contingency. Because Aristotle wavers in his understanding we sometimes write ‘CON’(P) to indicate that the notion of contingency is uncertain in one way or another.

If this interpretation is correct, then Aristotle presumably also accepts ( CaN). Notes 1. The reader can be sure that any variable letter other than ‘A’, ‘B’, ‘C’, ‘D’ and ‘E’ has no correspondent in the Greek original. 2. In the Introduction and Summary we ignore Aristotle’s treatment of so-called indeterminate propositions, ‘X holds of Y’ and ‘X does not hold of Y’. 3. We also use the word ‘syllogism’ to mean roughly ‘valid inference’. If the Notes to pp. 5-13 35 premisses P1 and P2 are syllogistic, Alexander says things such as ‘There is (or will be) a syllogism’, and if the conclusion yielded is P3, he often says there is a syllogism of P3.
