In this episode Julia interviews Massimo about his new book, Answers for Aristotle: How Science and Philosophy Can Lead Us to A More Meaningful Life. Massimo's central idea is that a combination of science and philosophy, what he calls "Sci-Phi," is the best guide to the big questions in life, from issues of morality and justice to the meaning of love and friendship. The book's title derives from the fact that Aristotle was the first philosopher-scientist, adopting the sci-phi framework and posing a number of questions with which we are still struggling. What is the best way to live one's life? What sort of society do we want to live in? How do we relate to our friends and loved ones? Two and a half millennia later, modern science and philosophy have come up with some of the answers to Aristotle's questions, or at the least with a better way to think about them.
