"In like manner the effect of every action is measured by the depth of the sentiment from which it proceeds. The great man knew not that he was great. It took a century or two for that fact to appear. What he did, he did, he did because he must; it was the most natural thing in the world, and grew out of the circumstances of the moment."

Evolution goes beyond what went before, but because it must embrace what went before, then its very nature is to transcend and include and thus it has an inherent directionality, a secret impulse, toward increasing depth, increasing intrinsic value, increasing consciousness. In order for evolution to move at all, it must move in those directions-there's no place else for it to go!
