It's safe to say that Plato and his contemporaries never grappled with moral questions raised by the development of neural networks or issues surrounding data privacy and security. But a few modern philosophers – like Kathleen Creel – are doing just that as they harness age-old ideas about knowledge, existence, and ethics to understand and respond to the challenges posed by today's technology. "I still get a lot from Plato and other historical philosophers, but the task of philosophy is to figure out what the questions of a particular age, of a particular society or culture are, and to ask how philosophy can help to address them," Creel says. "It gives us a clearer moral system to help sort through what our priorities ought to be, and how we should act in our lives." Creel is finishing a two-year Embedded EthiCS Postdoctoral Fellowship based at Stanford's McCoy Family Center for Ethics in Society and the Institute for Human-Centered Artificial Intelligence (HAI).
