Philosopher Julian Baggini, author of How to Think Like a Philosopher, talks to writer and translator Daniel Hahn about conveying big ideas, the importance of broadening audiences for big subjects and the value of simplicity while also holding on to complexity. He uses everyday examples and contemporary political concerns – from climate change to implicit bias – to explore the techniques, methods and principles that guide philosophy, and how they can be applied to our own lives, proving that philosophical thought can promote incisive thinking.
