Are there new colors you could see? And why are they impossible to imagine before you've seen them? Can you lose your color vision? And what does any of this have to do with linguistic color terms, why the military likes colorblind people for a particular task, and why Eagleman suggests that the cultural history of Thailand was influenced by one single, unknown neurodivergent? 

Why do birds and bees choose different flowers? Why do mammals' eyes seem to be optimized for moving around at night, and what does that have to do with hairless humans getting angry? What does any of this have to do with road signs, camouflage, mantis shrimp, the sun, the dress that broke the internet, and women who can see more colors than you can?

Would you eat a burger grown from a human muscle cell? Would you rather use your own cell or someone else's? What does the future of lab-grown meat illuminate about neuroscience, our calculations of morality, and whether your grandchildren will have a different answer? What does any of this have to do with endangered species, the sacred versus the profane, brain plasticity, moral positioning, social belonging, stepping on the boundary between mental categories, flesh copyrights, and the future of personhood? 

Why do some people jump into entirely new categories of possibility? And what does this have to do with self-driving ships, solar panels in space, shooting mosquitoes with lasers, skateboarding tricks, silent drones, and our future as a species? Join Eagleman with guest Pablos Holman, a venture capitalist, author, and connoisseur of invention.

What is code, and can it be thought of like a magic spell? Are we building a world so complex that we will lose the ability to understand its operations -- and has that already happened? What does any of this have to do with SimCity, or knowledge that already exists but no one has put together, or how coding will evolve in the near future? Join Eagleman with scientist Sam Arbesman, who has just written a book asking the question: what is code, really?

What is intelligence? If we look hard, can we find it in unexpected places: not just in brains but in all kinds of structures? How should we recognize it? And what does any of this have to do with a bipedal dog born without front legs, or making small new organisms out of single cells, or   how Wikipedia might be like an axolotl, or why we are so blind to the vast variety of minds that might surround us? Join Eagleman with guest Michael Levin, professor at Tufts, about how we might discover intelligence all around us in ways we don't typically intuit.

Can we explain consciousness as emerging from classical neuroscience, or do we require deeper principles? Could quantum physics have something to do with it? Is it possible that consciousness predates biology, and biology evolved to take advantage of it? What are the right ways to build new theories in neuroscience when we don’t know the answers? Join Eagleman with Nobel laureate Roger Penrose and anesthesiologist Stuart Hameroff to explore the controversial idea that there could be, even possibly, any connection between quantum theory and our awareness of the world.

Brains bear thoughts like a peach tree bears peaches. Even for meditators it's almost impossible to stop the firehose of words and images and ideas. But what in the world is a thought, physically? How can you hear a voice in your head when there's no one speaking in the outside world? And what does any of this have to do with a small marine animal who eats its own brain? Join Eagleman for this week's deep dive into our inner life.

Is your brain a one-person show or an ensemble cast of rivaling neural networks? How do we manage the conflict between different drives, and what does this have to do with literature, deities, maturation, and what Nietzsche meant when he said “every drive wants to be master, and it attempts to philosophize in that spirit”? Join Eagleman this week with Jordan Peterson as we examine the way lives are built on conflicting wants.

Is it possible to become happier? How much of your happiness has to do with genetics, social connection, comparison to other people, your balance of optimism vs pessimism, and whether it would be useful to keep a journal of your life? Join Eagleman this week with Bruce Hood, experimental psychologist and author of “The Science of Happiness”.
