Julian Baggini and guests Nilanjan Das and Leah Kalmanson explore how the exemplary habits and principles of the best philosophers can help us to think better. Their focus today is on the value of contemplative practices, and shifting the burden of proof. They take as their cue Baggini’s new book How to Think Like a Philosopher, in which he offers 12 key principles for a more humane, balanced and rational approach to thinking.
