Book excerpt: Everything I Know I Learned From TV uses characters we all know and love and their TV worlds to explain the great questions of philosophy. The only qualifications you need to join in are ownership of a sofa, a remote control, a sense of humour and an enquiring mind. The philosophy discussed is very much 'life' philosophy, answering the questions we all want to know: How do you define what is a good life to lead? The Simpsons disagree over the right way to live with Nietzsche and Diogenes on hand to take sides. What is real happiness? Aristotle fights Descartes for the heart and mind of Sex and the City's Carrie Bradshaw. Can a good person do a bad thing? Kant and Socrates pay a call on Tony Soprano and his latter-day Mob to talk moral philosophy. Where does love end and friendship begin? Rachel and Ross ask Plato about the philosophy of emotions and wonder if they're just good friends. Is the pursuit of self-knowledge a good thing? Socrates helps Niles and Frasier Crane and their dad deal with the relative merit of the examined and the unexamined life. And much more.
