 Every other nation in the history of the world is based on geography, ethnicity, religion, or some other attribute. But we're the only nation founded on an idea. That idea is all men are created equal, deservedly treated equally throughout their lives. We haven't always lived up to that. But like George and Philip, we've never walked away from it either. The heroic deeds went unacknowledged for over a century. But time did not erase their valor.
