This episode is brought to you by AeroPressIf you haven’t tried coffee made with an AeroPress, you’re in for a treat. With more than 45,000 five-star reviews and customers in more than 60 countries, it might be the highest-rated coffee maker on the planet. This press uses a patented 3-in-1 technology that combines the best of several brew methods into one, easy-to-use, very portable device. Because it combines the best of 3 methods, you get a cup that is full bodied like a French press, smooth and complex like when using the pour-over method and rich in flavor like espresso.

As I wrote in The 4-Hour Chef: “This is now, bar none, my favorite brewing method.” And now they have a new Crystal Clear version—sleek enough for display and tough enough for the road. Pick one up at AeroPress.com/Tim for less than $50.

This episode is brought to you by Athletic Greens. I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1 by Athletic Greens, my all-in-one nutritional insurance. I recommended it in The 4-Hour Body in 2010 and did not get paid to do so. I do my best with nutrient-dense meals, of course, but AG1 further covers my bases with vitamins, minerals, and whole-food-sourced micronutrients that support gut health and the immune system. 

Right now, Athletic Greens is offering you their Vitamin D Liquid Formula free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones. Visit AthleticGreens.com/Tim to claim this special offer today and receive the free Vitamin D Liquid Formula (and 5 free travel packs) with your first subscription purchase! That’s up to a one-year supply of Vitamin D as added value when you try their delicious and comprehensive all-in-one daily greens product.

Want to hear another episode that ponders the nature of reality? Have a listen to my conversation with Professor Donald Hoffman here, in which we discuss the science of consciousness, how perception may influence the physical world, the holographic model of the universe, panpsychism (and influential panpsychists), cosmological polytope, the use of hallucinogenic drugs to tap into deeper reality and interact with conscious agents, QBism, the probability of zero that humans evolved to see reality in full, and much more wild stuff.

#585: Professor Donald Hoffman — The Case Against Reality, Beyond Spacetime, Rethinking Death, Panpsychism, QBism, and More

“The brain is locked in silence and darkness inside the skull, and all it ever sees are these little electrical signals … yet when you open your eyes and look at the world, you see everything in full color and it looks so rich and you’re hearing music and you’re feeling things on your fingertips and you’re smelling cinnamon. All these things seem like very distinct senses to you, but they’re all made of exactly the same stuff, which is these electrochemical spikes. And so I got really interested in this idea of could we feed information into the brain via an unusual source, and would the brain just figure it out?”

— David Eagleman

“We experience lots of data. When you’re a kid, when you’re a baby, you don’t know how the heck to use your eyes or ears or whatever. You’re just getting all this data going into the darkness there and you figure stuff out. You figure out correlations.”

— David Eagleman

“Memory is a myth-making machine, and we’re constantly reinventing our past, especially as we tell the stories over and over again.”

— David Eagleman

“I think the notion of how plastic the brain actually is is something that’s totally underappreciated. There’s an idea that I think many people have, which is, “Oh, you’re just born with the brain. The brain unpacks and then you’re who you are,” but really, we are totally functions of our culture and our society. And one of the things that’s amazing to me is, imagine, Tim, that you and I were born 10,000 years ago, exactly the same DNA, but we wouldn’t be anything like what we are now. Even though with the same DNA we might look vaguely like we do now, but my God, the culture, everything we’re pulling in would be so different. And that’s what actually shapes a human being.”

— David Eagleman

“The beauty of science is that it’s always willing to knock down its own walls.”
