Abstract:

The concept of truth serves in logic not only as an instrument but also as an object of study. Eubulides of Miletus (fl. fourth century BCE), a Megarian logician, discovered the paradox known as ‘the Liar,’ and, ever since his discovery, logicians down the ages - Aristotle and Chrysippus, John Buridan and William Heytesbury, and Alfred Tarski and Saul Kripke, to mention just a few - have tried to understand the puzzling behavior of the concept of truth.

Comment : Can be used in an advanced course on (formal approaches to) truth or the Liar paradox. Familiarity with the semantics of first-order classical logic and transfinite induction is assumed (for the latter, Ch.3 of the Blackwell Guide might be of help - using the Blackwell Guide as a blueprint may also be a way to incorporate this reading in a general advanced course on philosophical logic).
