Added by: Berta Grimau, Contributed by: Giada FratantonioSummary: A comprehensive introduction to ancient (western) logic from the 5th century BCE to the 6th century CE, with an emphasis on topics which may be of interest to contemporary logicians. Topics include pre-Aristotelian logic, Aristotelian logic, Peripatetic logic, Stoic Logic and a note on Epicureans and their views on logic.Comment: This paper would be ideal as an introductory overview for a course on ancient logic. Alternatively, it could serve as an overview for a module on ancient logic within a more general course on the history of logic. No prior knowledge of logic is required; formalisms are for the most part avoided in the paper. Note that this is a SEP entry, so it's completely accessible to students.McConaughey, Zoe.

Added by: Viviane FairbankAbstract:
This paper stresses the importance of identifying the nature of an author’s conception of logic when using terms from modern logic in order to avoid, as far as possible, injecting our own conception of logic in the author’s texts. Sundholm (2012) points out that inferences are staged at the epistemic level and are made out of judgments, not propositions. Since it is now standard to read Aristotelian sullogismoi as inferences, I have taken Alexander of Aphrodisias’s commentaries to Aristotle’s logical treatises as a basis for arguing that the premises and conclusions should be read as judgments rather than as propositions. Under this reading, when Alexander speaks of protaseis, we should not read the modern notion of proposition, but rather what we now call judgments. The point is not just a matter of terminology, it is about the conception of logic this terminology conveys. In this regard, insisting on judgments rather than on propositions helps bring to light Alexander’s epistemic conception of logic.
Comment: This text uses the case of Alexander of Aphrodisias’s commentaries to Aristotle’s logical treatises as a basis for making a philosophical argument about the distinction between conceptions of logic that focus on propositions, and those that focus on judgments. It is appropriate for students who already have some background in Ancient logic as well as contemporary philosophy of logic. Although the text requires some prior understanding of relevant concepts, it is clear and accessible, and would be appropriate for a course on the history of logic.Can’t find it?Contribute the texts you think should be here and we’ll add them soon!
