"So I don’t get overwhelmed, because I don’t think about what I don’t know as oppressive to me. If you think of it as oppressive, or if you have a measure of your ego that’s larger than nature provides for you, then it’s possible that you could end up quite depressed, seeing how small we are on Earth, [orbiting] around an ordinary star in an undistinguished corner of our galaxy between a hundred billion other galaxies. That’s upsetting to some people, because it destabilizes their sense of self-worth. I would assert that it’s not inherently destabilizing to learn this—it’s only destabilizing if you walked into the room with an unjustifiably high ego to begin with. If you come in with a humble enough ego, all of this is kind of enlightening instead of depressing."
