In this podcast, Pinker discusses some of the philosophical underpinnings for rationality, but I think it will be very basic for people who are knowledgeable about philosophy. I liked the part where they talk about challenging yourself about what if you're wrong about various things you think and what percentage of certainty do you have. From the description: The Harvard linguist says Enlightenment reasoning and critical thinking are behind massive increases in material and moral progress. In the controversial yet bestselling books The Better Angels of Our Nature and Enlightenment Now, Harvard linguist Steven Pinker made the case that humanity has been getting richer and less violent over the past two centuries. In his new book, Rationality: What It Is, Why It Seems Scarce, Why It Matters, he argues that our ability to reason and think critically is central to human flourishing and undergirds our phenomenal material and moral progress since the Enlightenment. Pinker lays out the basic cognitive biases that cloud our thinking and give rise to intensely polarized and tribalistic worldviews that threaten continued advances. And he tells Reason's Nick Gillespie how all of us can become better, sharper thinkers in all aspects of our lives.
