Draft for a Statement of Human Obligation (1943)
Context: It is impossible to feel equal respect for things that are in fact unequal unless the respect is given to something that is identical in all of them. Men are unequal in all their relations with the things of this world, without exception. The only thing that is identical in all men is the presence of a link with the reality outside the world.
All human beings are absolutely identical in so far as they can be thought of as consisting of a centre, which is an unquenchable desire for good, surrounded by an accretion of psychical and bodily matter.

2000s, Is Diversity Good? (2003)
Context: To allow slavery to be introduced into free territories, where it had not hitherto existed, was, Abraham Lincoln held, a very bad thing. His opponent, Stephen A. Douglas, held that it was a sacred right, belonging to the people of each territory, to decide for themselves whether or not to have slavery among their domestic institutions. According to Douglas, Lincoln wanted to destroy the diversity upon which the union had subsisted, by insisting that all the states ought to be free. But for Douglas himself, the principle of 'popular sovereignty' did not admit of exceptions. There was to be no diversity, no deviation from the right of the people to decide. For Lincoln the wrongness of slavery meant that no one, and no people, had the right to decide in its favor. For Lincoln, the principle of human equality, "that all men are created equal", did not admit exceptions.
