For the artist, the goal of the painting or musical composition is not to convey literal truth, but an aspect of a universal truth that if successful, will continue to move and to touch people even as contexts, societies and cultures change. For the scientist, the goal of a theory is to convey "truth for now"--to replace an old truth, while accepting that someday this theory, too, will be replaced by a new "truth," because that is the way science advances.

Most of what we know we don't really know first hand. I've never seen a cancer cell. But I trust this community of experts who have, so I believe that cancer exists. But we trust these experts, and we trust that the experts have a system of checks and balances and self-correction. And we have to insist that experts have certain certifications. They're not perfect. Every once in awhile there's an engine falls off the wing of a plane, or a tax audit happens and you find out your expert made a mistake. But it's a pretty good system. It's the best system we've got.

I agree with the sentiment that it's probably more dangerous to believe some things that aren't so than to not believe something - you know, to believe in a lie.

When a language advances and adds a third term to its lexicon for color, the third term is always red.

In order to be a world-class expert in anything, be it audiology, drama, music, art, gymnastics, whatever, one needs to have a minimum of 10,000 hours of practice. Unfortunately, it doesn't mean that if you put in 10,000 hours that you will become an expert, but there aren't any cases where someone has achieved world-class mastery without it! So the time spent at the activity is indeed the most important and influential factor.

The brain has an attentional mode called the "mind wandering mode" that was only recently identified. This is when thoughts move seamlessly from one to another, often to unrelated thoughts, without you controlling where they go. This brain state acts as a neural reset button, allowing us to come back to our work with a refreshed perspective. Different people find they enter this mode in different ways: reading, a walk in nature, looking at art, meditating, and napping. A 15-minute nap can produce the equivalent of a 10-point boost in IQ.

People are trying to build a society where they can talk across the aisle so to speak, and have civil discourse. At the same time we're trying to inform ourselves about what's really true so that we can make evidence based decisions that is better than superstition or rumor. But the fact is that people who use evidence based decision making have much better life outcomes, greater life satisfaction, they live longer, they make better personal and medical decisions, better financial decisions. But parallel to that is you can't reason somebody out of a position they didn't reason themselves into.
