What is the nature of consciousness? Is there a self? Is the mind identical to the brain? Can life have meaning in a physical universe? These are big questions that philosophy can help tackle. Together, we will talk about how to understand these questions more precisely, look at some answers, and learn how to approach both questions and answers using critical thinking tools. Who is this class for? Students who've never taken philosophy, adults who are interested in exploring big ideas, and scientists and entrepreneurs who'd like to learn how to think about these questions in a more rigorous way.
