“Society never advances. It recedes as fast on one side as it gains on the other. It undergoes continual changes; it is barbarous, it is civilized, it is christianized, it is rich, it is scientific; but this change is not amelioration. For every thing that is given, something is taken. Society acquires new arts, and loses old instincts. What a contrast between the well-clad, reading, writing, thinking American, with a watch, a pencil, and a bill of exchange in his pocket, and the naked New Zealander, whose property is a club, a spear, a mat, and an undivided twentieth of a shed to sleep under! But compare the health of the two men, and you shall see that the white man has lost his aboriginal strength. If the traveller tell us truly, strike the savage with a broad axe, and in a day or two the flesh shall unite and heal as if you struck the blow into soft pitch, and the same blow shall send the white to his grave.The civilized man has built a coach, but has lost the use of his feet. He is supported on crutches, but lacks so much support of muscle. He has a fine Geneva watch, but he fails of the skill to tell the hour by the sun. A Greenwich nautical almanac he has, and so being sure of the information when he wants it, the man in the street does not know a star in the sky. The solstice he does not observe; the equinox he knows as little; and the whole bright calendar of the year is without a dial in his mind. His note-books impair his memory; his libraries overload his wit; the insurance-office increases the number of accidents; and it may be a question whether machinery does not encumber; whether we have not lost by refinement some energy, by a Christianity entrenched in establishments and forms, some vigor of wild virtue. For every Stoic was a Stoic; but in Christendom where is the Christian?”

“Each man takes care that his neighbor shall not cheat him. But a day comes when he begins to care that he does not cheat his neighbor. Then all goes well - he has changed his market-cart into a chariot of the sun.”

“Human-heartedness is man's mind. Righteousness is man's path. How sad that he abandons that path and does not rely on it; that he loses that mind and does not know to seek it. When a man has lost a cock or a dog, he knows to seek it, but having lost his (proper) mind, he does not know to seek it. The Way of Learning is nothing other than seeking the lost mind”

“Infidelity does not consist in believing, or in disbelieving; it consists in professing to believe what he does not believe. It is impossible to calculate the moral mischief, if I may so express it, that mental lying has produced in society. When a man has so far corrupted and prostituted the chastity of his mind, as to subscribe his professional belief to things he does not believe, he has prepared himself for the commission of every other crime.”

“Every man has some reminiscences which he would not tell to everyone, but only to his friends. He has others which he would not reveal even to his friends, but only to himself, and that in secret. But finally there are still others which a man is even afraid to tell himself, and every decent man has a considerable number of such things stored away. That is, one can even say that the more decent he is, the greater the number of such things in his mind.”
