The aim of this class is to turn you into an Aristotelian! The Aristotelian view of nature is often derided as simple-minded by students of the modern scientific revolution. In fact, it was a brilliant synthesis of much of the best natural philosophy before the modern era. The Aristotelian world-view is relentlessly rational and coherent and is in many respects the true foundation of modern science. It is also interesting and delightful in itself. P.S.: The Aristotelian world-view provides an excellent—and often amusing—way to explain the natural world to your younger grandchildren!

Talking About Climate Change in a Divided World explores the challenges and opportunities of communicating about climate change across political, cultural, and social divides. This one-hour talk examines why facts alone often fail to persuade, how values and identity shape public responses, and what strategies can foster more constructive conversations. Drawing on research in communication, psychology, and public engagement, the session offers practical approaches for discussing climate change in ways that build trust, reduce polarization, and inspire meaningful action across diverse audiences.

The class will consist of a lecture-style presentation followed by a Q&A period and discussion. We will explore the following questions: How will an increasing life expectancy affect society? Why do we age? Can aging be reversed or treated?
