“First, individual rights cannot be sacrificed for the sake of the general good, and second, the principles of justice that specify these rights cannot be premised on any particular vision of the good life. What justifies the rights is not that they maximize the general welfare or otherwise promote the good, but rather that they comprise a fair framework within which individuals and groups can choose their own values and ends, consistent with a similar liberty for others.”

“It is above all in the present democratic age that the true friends of liberty and human grandeur must remain constantly vigilant and ready to prevent the social power from lightly sacrificing the particular rights of a few individuals to the general execution of its designs. In such times there is no citizen so obscure that it is not very dangerous to allow him to be oppressed, and there are no individual rights so unimportant that they can be sacrificed to arbitrariness with impunity.”

“The object of this Essay is to assert one very simple principle, as entitled to govern absolutely the dealings of society with the individual in the way of compulsion and control, whether the means used be physical force in the form of legal penalties, or the moral coercion of public opinion. That principle is, that the sole end for which mankind are warranted, individually or collectively in interfering with the liberty of action of any of their number, is self-protection. That the only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant. He cannot rightfully be compelled to do or forbear because it will be better for him to do so, because it will make him happier, because, in the opinions of others, to do so would be wise, or even right. These are good reasons for remonstrating with him, or reasoning with him, or persuading him, or entreating him, but not for compelling him, or visiting him with any evil, in case he do otherwise. To justify that, the conduct from which it is desired to deter him must be calculated to produce evil to someone else. The only part of the conduct of any one, for which he is amenable to society, is that which concerns others. In the part which merely concerns himself, his independence is, of right, absolute. Over himself, over his own body and mind, the individual is sovereign.”

“[T]he state should not impose a preferred way of life, but should leave its citizens as free as possible to choose their own values and ends, consistent with a similar liberty for others.”

“And what is true education? It is awakening a love for truth; giving a just sense of duty; opening the eyes of the soul to the great purpose and end of life. It is not so much giving words, as thoughts; or mere maxims, as living principles. It is not teaching to be honest, because 'honesty is the best policy'; but because it is right. It is teaching the individual to love the good, for the sake of the good; to be virtuous in action because one is so in heart; to love and serve God supremely, not from fear, but from delight in his perfect character.”

“Realism maintains that universal moral principles cannot be applied to the actions of states in their abstract universal formulation, but that they must be filtered through the concrete circumstances of time and place. The individual may say for himself: "Fiat justitia, pereat mundus (Let justice be done, even if the world perish)," but the state has no right to say so in the name of those who are in its care. Both individual and state must judge political action by universal moral principles, such as that of liberty. Yet while the individual has a moral right to sacrifice himself in defense of such a moral principle, the state has no right to let its moral disapprobation of the infringement of liberty get in the way of successful political action, itself inspired by the moral principle of national survival.”
