There is always a place I can take someone's curiosity and land where they end up enlightened when we're done. That's my challenge as an educator. No one is dumb who is curious. The people who don't ask questions remain clueless throughout their lives.

In all civilizations we've studied, all cultures that we know of across the Earth and across time have invested some kind of attempt to understanding where where, where they come from, and where they are going.

Let's say intelligence is your ability to compose poetry, symphonies, do art, math and science. Chimps can't do any of that, yet we share 99 percent DNA. Everything that we are, that distinguishes us from chimps, emerges from that one-percent difference.
