Everybody believes in something they can't prove.
The rationalist believes reason can solve everything—but that's a leap of faith, not a fact. The scientist trusts that the universe makes sense and can be understood, which is a bet, not a proof. The humanist believes people have dignity and rights, a beautiful idea you can't find under a microscope.
We're all standing on something. The only question is whether you've ever looked down at your feet.
We've looked. What we found there is Christianity—and we think it's been badly undersold.
