Deeply Knowing

I think the most important distinction in knowledge is whether you intellectually understand something to be true, or deeply know it.

I don’t know a perfect word for “deeply knowing something.” Here are a few candidate phrases: “internalized understanding,” “feeling it,” “emotional understanding,” and “the idea resonates.”

I wish there was a good word, because this distinction is both specific and important.

Here’s an example: imagine intellectually understanding that other cultures are different than your own.

No doubt you understand that people in different parts of the globe have different ways of going about their day. They eat different foods. They speak in different languages. They have different perspectives about what is important in relationships, society, and being a good human being. You can truly understand these facts, and you would surely tell anyone who asked you that you are 100% certain of them.

But you achieve a different kind of understanding when you experience the reality of different cultures. It’s like you add belief to knowledge.

I’m not sure what it is about the chemistry of experience that deepens understanding. It might be grounding facts in the senses: seeing, smelling, and hearing something yourself. It might be that an abstract ideas becomes concrete when you actually experience it—being with people cooking, talking, and working in specific ways. Or maybe it’s something a bit more complex; there’s some kind of cognitive bouncing you do when you:

  • see something new
  • compare to what you are used to
  • realize that they’re different instances of the same thing
  • redefine how you conceptualize that thing
  • …and then go back to concrete observations.

It could be that bouncing around abstractions itself is what makes this new understanding possible and meaningful.

But whatever makes it happen, a deeply internalized piece of knowledge has a different texture than an idea that you hold intellectually. It digs a meaty trench in your brain. This new state of acceptance seems more liable to influence your behavior and future ideas.

Traveling is a cliched example here because it’s a reliable way to kickstart this in someone. This is why college students who come back from study abroad are so annoying. They’ve had a truly important change in understanding, but all they can show for it are banal platitudes that are irritating to listen to.

I remember a friend asking me whether there was anything unique I learned in the experience of studying abroad.01 I thought about it and said “no.” There wasn’t any kind of new understanding I had that I couldn’t theoretically have developed if I’d stayed in Seattle. Most of the ideas that seemed important to me were just taking things I already knew with a grain of salt. The way I grew up was now “one way of living” and not simply “how life works.”

And yet that kind of understanding probably wouldn’t have happened if I hadn’t left. The experience wasn’t necessary, but it was sufficient. How should I have expressed this? I didn’t gain anything that my friend couldn’t have, and for all I knew, he came to the same understanding without going anywhere. After all, how can you “test” whether someone believes something deeply?

A final thought: a hallmark of this distinction is that it makes the complexity of an idea irrelevant to its importance. Some of the simplest ideas—like “love is paramount,” which of course has had all meaning cliched out of it—are completely life-shaping if known with sufficient depth.


Having books by Plato or the Dalai Lama on your bookshelf doesn’t make you wise, and neither does reading them.

If you want to think about some of these ideas a bit more:

  • Infinite Jest by David Foster Wallace (Little, Brown and Company, 1996) — DFW was obsessed with the idea of life’s most important realizations being rendered as banal platitudes. Infinite Jest is a long and excruciating but (I think) rewarding read, and you get to watch a few different characters struggle to express this idea.02

  • Samsara dir. Ron Fricke (Oscilloscope Laboratories, 2011) — This beautiful documentary is the closest I’ve gotten to virtual traveling.

  • How to Change Your Mind by Michael Pollan (Penguin Press, 2018) — While this book is no exception to “nonfiction bloat,”03 it recounts and tries to conceptualize this same idea of gaining a newfound, deep belief in simple ideas.

  2. Aside: I know DFW is now like weirdly a villain as an author, which is too bad. (The correct response to someone mentioning him is supposed to be an eye roll.) ↩︎

  3. I should look up whether there’s already an established term for “400 page books with 20 pages of interesting content” AKA every nonfiction book I’ve ever read. ↩︎
