Avery Kolers is Professor of Philosophy at the University of Louisville. He has longstanding research interests in issues surrounding territorial rights and solidarity. These highly applied issues touch on a wide range of problems, but also raise hard questions about how to navigate deep diversity in a shared world. More recently he has been researching the philosophy of sports and games, in order to better understand ethical behavior as embodied skill, and to articulate the kinds of sociability made possible by games, and the prospects for incorporating this sociability into everyday life. He is co-Editor in Chief of the Journal of Applied Philosophy and serves on the editorial board of Political Philosophy.
