"The facts of man's history do not fully represent the faculties of his nature as the history of matter represents the qualities of matter. Man, though finite, is indefinitely progressive, continually unfolding the qualities of his nature; his history, therefore, is not the whole book of man, but only the portion thereof which has been opened and publicly read. So the history of man never completely represents his nature; and a law derived merely from the facts of observation by no means describes the normal rule of action which belongs to his nature. The laws of matter are known to us because they are kept; there the ideal and actual are the same; but man has in his nature a rule of conduct higher than what he has come up to, — an ideal of nature which shames his actual of history. Observation and reflection only give us the actual of morals; conscience, by gradual and successive intuition, presents us the ideal of morals."

“The books that help you the most are those which make you think the most.”

“In America, the Democratic Party thinks slavery is 'indispensable to good government', and is 'the normal condition of one seventh part of the people'.”

“Justice is moral temperance in the world of men. It keeps just relations between men; one man, however little, must not be sacrificed to another, however great, to a majority, or to all men. It holds the balance betwixt nation and nation, for a nation is but a larger man; betwixt a man and his family, tribe, nation, race; between mankind and God. It is the universal regulator which coordinates man with man, each with all, — me with the ten hundred millions of men, so that my absolute rights and theirs do not interfere, nor our ultimate interests ever clash, nor my eternal welfare prove antagonistic to the blessedness of all or any one. I am to do justice, and demand that of all, — a universal human debt, a universal human claim.”

“The people are not satisfied with any form of government, or statute law, until it comes up to their sense of justice; so every progressive State revises its statutes from time to time, and at each revision comes nearer to the absolute right which human nature demands. Mankind, always progressive, revolutionizes constitutions, changes and changes, seeking to come close to the ideal justice, the divine and immutable law of the world, to which we all owe fealty, swear how we will.”

“Every rose is an autograph from the hand of the Almighty God. On this world about us He has inscribed His thought, in these marvelous hieroglyphics which sense and science have been these many thousand years seeking to understand. The universe itself is a great autograph of the Almighty.”

“Truth never yet fell dead in the streets; it has such affinity with the soul of man, the seed however broadcast will catch somewhere and produce its hundredfold.”
