"It is the principle of necessity towards which, as to their ultimate centre, all the ideas advanced in this essay immediately converge. In abstract theory the limits of this necessity are determined solely by considerations of man’s proper nature as a human being; but in the application we have to regard, in addition, the individuality of man as he actually exists. This principle of necessity should, I think, prescribe the grand fundamental rule to which every effort to act on human beings and their manifold relations should be invariably conformed. For it is the only thing which conducts to certain and unquestionable results. The consideration of the useful, which might be opposed to it, does not admit of any true and unswerving decision."

“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.”
