At first, man was enslaved by the gods. But he broke their chains. Then he was enslaved by the kings. But he broke their chains. He was enslaved by his birth, by his kin, by his race. But he broke their chains.

And he stood on the threshold of freedom for which the blood of the centuries behind him had been spilled.
