““If you fret that the world grows short of genuine wonders, consider this: the most complex lump of matter in the universe. It works in ways we can only guess at. THrough generations of intense study, scientists have at last come to understand some of its local mechanism, but the connection between local and general remains for them, as for the rest of us, a matter of arm-waving speculation--we know less about what's going on inside of it than we do about the functional structure of the most distant galaxies. It weighs a little over three pounds and is the consistency of toothpaste; you're carrying it between your ears.””
