" We are, however, creatures of containment. We want all things in life packed into boxes that we can label. But just because we have the ability to label it, doesn't mean we really know what's in the box.

It's kind of religion. It gives us comfort to believe we have defined something that is, by its very nature, indefinable. As to whether or not we've gotten it right, well, it's all a matter of faith. "
