Language is a huge part of human development, even the language we keep to ourselves. Three experts explain how words and beliefs can change our brains and our lives:

When Jesus was crucified, it led to even more followers. When books are banned, people flock to read them. Humans are fascinated by the forbidden, which is why censorship – especially in the digital age – doesn’t work. Jacob Mchangama explains.

"Could black holes be the key to a quantum theory of gravity, a deeper theory of how reality, of how space and time works? Well, I think so."

"If you're interested in human performance, what you want is something that's reliable and repeatable, and thus you want neurobiology because neurobiology gives you mechanism."

How can the brain — a piece of matter — love? Physics and chemistry explain the material world, but they can’t explain why it feels like something to be alive. This is the mystery of consciousness, according to these experts.

Free speech may be messy, but censorship is deadly. Founder of The Future of Free Speech Jacob Mchangama explains.

A physician, a psychologist, and a mindfulness teacher explain what stress does to your body and mind, and how to use it to get smarter and stronger.

“There's research showing that people who are curious, who ask questions, are not just happier, they're not just more successful, they also live longer.”

Everything you experience is filtered through your brain, and everyone’s brain is different. Neuroscientist Christof Koch explains how understanding this can deepen your connection to the world around you.

Biologist Tyler Volk PhD, psychiatrist Bruce Greyson MD, and palliative care physician BJ Miller MD, reveal how confronting mortality can improve the way we live.

“The idea of evolution by natural selection is, for me, probably the most beautiful idea in biology.”

“You can be aware of sadness from a point of view that is not merely sad, and you can be aware of fear from a point of view that's not merely afraid.”

Humans have always had religion. What does this say about our minds? Reza Aslan PhD, Lisa Miller PhD, and Rob Bell MDiv explain.

Many of us rely on emotional advice that doesn’t actually work. Psychologist Ethan Kross offers a smarter, science-backed approach to managing emotions with flexibility and perspective.

“Because of the efficiency worship that we have developed in our industrial age, we are now seeing procrastination as a character flaw rather than what it is, a signal that is worth listening to.”

What happens when the boundaries of “you” disappear? James Fadiman, PhD, Jamie Wheal, and Matthew Johnson, PhD explore how supported experiences with psychoactive drugs can dissolve identity and reveal a deeper reality.

“What did you win? You won awkward silence. You won their contempt. You won the first to apologize. When you win an argument, you will lose their confidence, you will lose their respect, you will lose the connection.”

"The sense that we are a solid entity, an unchanging entity that exists someplace in our body and takes ownership of our body, and even ownership of our brain rather than being identical to our brain, that is where the illusion lies."

“The simplest, most powerful way to reinforce work, not jobs, is to ask people to do something different.”

Today’s technologist archetypes share a blind spot. Brendan McCord, founder of the Cosmos Institute explains why “philosophy is essential” when building planetary-scale technology.
