Professor Politis specializes in Ancient Greek Philosophy. With the publication of The Structure of Enquiry in Plato’s Early Dialogues (Cambridge, 2015), and following numerous papers in leading journals and presses, he recently completed a major research project, on the function of aporia—puzzlement and particular puzzles—in the method of argument and enquiry of Plato and Aristotle. The significance of this project has been recognized not least through the collection of papers due to appear on this topic, and covering the whole of Ancient Philosophy, by fourteen eminent scholars worldwide: The Aporetic Tradition in Ancient Philosophy (Cambridge, 2017), edited by Professor Politis and George Karamanolis of Vienna. He believes that this topic—the function of aporia in intellectual enquiry—is of great interest for philosophy generally and indeed beyond academic enquiry.
