Sam Harris speaks with Neil deGrasse Tyson about his new book, Starry Messenger. They discuss what makes science a unique human endeavor, the tension between respecting scientific consensus and overturning it, confusion about paradigm shifts and scientific controversies, the social importance of probability and statistics, climate change, the consequences of exponential cultural change, social media, social inequality and affirmative action, identity politics and a post-racial future, the wisdom of focusing on class rather than race, and other topics.

Learning how to train your mind is the single greatest investment you can make in life. That’s why Sam Harris created the Waking Up app. From rational mindfulness practice to lessons on some of life’s most important topics, join Sam as he demystifies the practice of meditation and explores the theory behind it.
