"If we would indicate an idea which, throughout the whole course of history, has ever more and more widely extended its empire, or which, more than any other, testifies to the much-contested and still more decidedly misunderstood perfectibility of the whole human race, it is that of establishing our common humanity — of striving to remove the barriers which prejudice and limited views of every kind have erected among men, and to treat all mankind, without reference to religion, nation, or color, as one fraternity, one great community, fitted for the attainment of one object, the unrestrained development of the physical powers. This is the ultimate and highest aim of society, identical with the direction implanted by nature in the mind of man toward the indefinite extension of his existence. He regards the earth in all its limits, and the heavens as far as his eye can scan their bright and starry depths, as inwardly his own, given to him as the objects of his contemplation, and as a field for the development of his energies. Even the child longs to pass the hills or the seas which inclose his narrow home; yet, when his eager steps have borne him beyond those limits, he pines, like the plant, for his native soil; and it is by this touching and beautiful attribute of man — this longing for that which is unknown, and this fond remembrance of that which is lost — that he is spared from an exclusive attachment to the present. Thus deeply rooted in the innermost nature of man, and even enjoined upon him by his highest tendencies, the recognition of the bond of humanity becomes one of the noblest leading principles in the history of mankind."

“Freedom exalts power; and, as is always the collateral effect of increasing strength, tends to induce a spirit of liberality. Coercion stifles power, and engenders all selfish desires, and all the mean artifices of weakness. Coercion may prevent many transgressions; but it robs even actions which are legal of a portion of their beauty. Freedom may lead to many transgressions, but it lends even to vices a less ignoble form.”

“In every remodelling of the present, the existing condition of things must be supplanted by a new one. Now every variety of circumstances in which men find themselves, every object which surrounds them, communicates a definite form and impress to their internal nature. This form is not such that it can change and adapt itself to any other a man may choose to receive; and the end is foiled, while the power is destroyed, when we attempt to impose upon that which is already stamped in the soul a form which disagrees with it.”

“Governmental regulations all carry coercion to some degree, and even where they don't, they habituate man to expect teaching, guidance and help outside himself, instead of formulating his own.”

“Setting aside the fact that coercion and guidance can never succeed in producing virtue, they manifestly tend to weaken power; and what are tranquil order and outward morality without true moral strength and virtue? Moreover, however great an evil immorality may be, we must not forget that it is not without its beneficial consequences. It is only through extremes that men can arrive at the middle path of wisdom and virtue.”

“Whatever does not spring from a man's free choice, or is only the result of instruction and guidance, does not enter into his very being, but still remains alien to his true nature; he does not perform it with truly human energies, but merely with mechanical exactness.”

“I am more and more convinced that our happiness or our unhappiness depends far more on the way we meet the events of life than on the nature of those events themselves.”
