“For, by the logic of Concord, Lexington, and Bunker Hill, and by the principles enforced by this nation in its boasted Declaration of Independence, Capt. Brown was a hero, struggling against fearful odds, not for his own advantage, but to redeem others from a horrible bondage, to be justified in all that he aimed to achieve, however lacking in sound discretion. And by the same logic and the same principles, every slave-holder has forfeited his right to live, if his destruction be necessary to enable his victims to break the yoke of bondage; and they, and all who are disposed to aid them by force and arms, are fully warranted in carrying rebellion to any extent, and securing freedom at whatever cost.”

Context: We must see that there is civic honesty, civic cleanliness, civic good sense in our home administration of city, State, and nation. We must strive for honesty in office, for honesty toward the creditors of the nation and of the individual; for the widest freedom of individual initiative where possible, and for the wisest control of individual initiative where it is hostile to the welfare of the many. But because we set our own household in order we are not thereby excused from playing our part in the great affairs of the world. A man's first duty is to his own home, but he is not thereby excused from doing his duty to the State; for if he fails in this second duty it is under the penalty of ceasing to be a freeman. In the same way, while a nation's first duty is within its own borders, it is not thereby absolved from facing its duties in the world as a whole; and if it refuses to do so, it merely forfeits its right to struggle for a place among the peoples that shape the destiny of mankind.

Seventh and Last Joint Debate with Steven Douglas, at Alton, Illinois (15 October 1858)

Context: Now, I have upon all occasions declared as strongly as Judge Douglas against the disposition to interfere with the existing institution of slavery. You hear me read it from the same speech from which he takes garbled extracts for the purpose of proving upon me a disposition to interfere with the institution of slavery, and establish a perfect social and political equality between negroes and white people. Allow me while upon this subject briefly to present one other extract from a speech of mine, more than a year ago, at Springfield, in discussing this very same question, soon after Judge Douglas took his ground that negroes were not included in the Declaration of Independence: I think the authors of that notable instrument intended to include all men, but they did not mean to declare all men equal in all respects. They did not mean to say all men were equal in color, size, intellect, moral development, or social capacity. They defined with tolerable distinctness in what they did consider all men created equal — equal in "certain inalienable rights, among which are life, liberty, and the pursuit of happiness." This they said, and this they meant. They did not mean to assert the obvious untruth that all were then actually enjoying that equality, or yet that they were about to confer it immediately upon them. In fact, they had no power to confer such a boon. They meant simply to declare the right, so that the enforcement of it might follow as fast as circumstances should permit. They meant to set up a standard maxim for free society which should be familiar to all, constantly looked to, constantly labored for, and even, though never perfectly attained, constantly approximated, and thereby constantly spreading and deepening its influence, and augmenting the happiness and value of life to all people, of all colors, everywhere... That is the real issue. That is the issue that will continue in this country when these poor tongues of Judge Douglas and myself shall be silent. It is the eternal struggle between these two principles — right and wrong — throughout the world. They are the two principles that have stood face to face from the beginning of time; and will ever continue to struggle. The one is the common right of humanity, and the other the divine right of kings. It is the same principle in whatever shape it develops itself. It is the same spirit that says, "You toil and work and earn bread, and I'll eat it." No matter in what shape it comes, whether from the mouth of a king who seeks to bestride the people of his own nation and live by the fruit of their labor, or from one race of men as an apology for enslaving another race, it is the same tyrannical principle.

Context: As for the "solitary confinement of the mind," my theory is that solipsism, like other absurdities of the professional philosopher, is a product of too much time wasted in library stacks between the covers of a book, in smoke-filled coffeehouses (bad for brains) and conversation-clogged seminars. To refute the solipsist or the metaphysical idealist all that you have to do is take him out and throw a rock at his head: if he ducks he's a liar. His logic may be airtight but his argument, far from revealing the delusions of living experience, only exposes the limitations of logic.
