“There will always be slaves, no matter what people promise and pretend.”

Context: There is a further and deeper reason why colonization failed and why all subsequent attempts to return Americans of African descent to Africa, even those originating solely within the black community, have failed. The reason is that the overwhelming majority of these Americans regard their destiny to be in the United States. They were, after all, sold into slavery originally by black tribesmen, who captured them in order to sell them, and who slaughtered the ones they did not sell. No resent of slavery, however profound, engendered any love of a mythical African homeland. To have asked them to return to Africa was not unlike asking American Jews whose parents or grandparents fled czarist or Stalinist tyranny to return to Russia. However involuntary their emigration from Africa, American Negroes, whether free or slave, have always seen America itself as the promised land. Both Christianity and the Declaration of Independence embodied promise to all men. They saw no better or equal hope anywhere else, and certainly not in Africa. The truth is that the slaves, ignorant and illiterate as they may have seemed, were far from unintelligent. The Bible that they heard about, even if they were not allowed to read it, contained stories that convinced them that the same God that had freed the children of Israel would free them. Jefferson Davis might have thought this to be mere credulity. Yet it certainly compared favorably with his own absurd reading of the story of Noah.

Poem
Context: Who but shall learn that freedom is the prize
Man still is bound to rescue or maintain;
That nature's God commands the slave to rise,
And on the oppressor's head to break the chain.
Roll, years of promise, rapidly roll round,
Till not a slave shall on this earth be found.

Context: We speak not strictly and philosophically when we talk of the combat of passion and of reason. Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them.
Context: What may at first occur on this head, is, that as nothing can be contrary to truth or reason, except what has a reference to it, and as the judgments of our understanding only have this reference, it must follow, that passions can be contrary to reason only so far as they are accompany'd with some judgment or opinion. According to this principle, which is so obvious and natural, `tis only in two senses, that any affection can be call'd unreasonable. First, When a passion, such as hope or fear, grief or joy, despair or security, is founded on the supposition or the existence of objects, which really do not exist. Secondly, When in exerting any passion in action, we chuse means insufficient for the design'd end, and deceive ourselves in our judgment of causes and effects. Where a passion is neither founded on false suppositions, nor chuses means insufficient for the end, the understanding can neither justify nor condemn it. `Tis not contrary to reason to prefer the destruction of the whole world to the scratching of my finger. `Tis not contrary to reason for me to chuse my total ruin, to prevent the least uneasiness of an Indian or person wholly unknown to me. `Tis as little contrary to reason to prefer even my own acknowledge'd lesser good to my greater, and have a more ardent affection for the former than the latter. A trivial good may, from certain circumstances, produce a desire superior to what arises from the greatest and most valuable enjoyment; nor is there any thing more extraordinary in this, than in mechanics to see one pound weight raise up a hundred by the advantage of its situation. In short, a passion must be accompany'd with some false judgment. in order to its being unreasonable; and even then `tis not the passion, properly speaking, which is unreasonable, but the judgment.
