Professor Olshewsky has retired from regular teaching at UK, but continues with research and publication as a Research Scholar at New College of Florida. His historical interests, primarily with works of Aristotle, Hume and Peirce, are motivated to mine their thoughts for contemporary understandings of thought and language in the ongoing debates in cognitive science, of which his "Functionalism Old and New" is a prime example. His work on Peirce has focused on the relation of his semiotics to pragmatism. Work with Hume concerns how his skepticism is shaped by his classical background. The main focus of Olshewsky's current work has been his attempt at a developmental model of Aristotle's conceptions of motion. This latter has led in recent years to presentations to the 2013 23rd World Congress of Philosophy in Athens, to the 2016 3rd International Congress of Greek Philosophy in Lisbon, to the 2016 World Congress of Aristotle in Thessaloniki (celebrating UNESCO's "Year of Aristotle" 2600 years after his birth), to the 2018 inaugural meeting of the Canadian Aristotle Society in Ottawa, and to various conferences and workshops in the United States.
