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.

John Stuart Mill, 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.... [T]he 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.... The only part of the conduct of any one, for which he is amenable to society, is that which concerns others.

The only proper, moral purpose of a government is to protect man's rights, which means: to protect him from physical violence—to protect his right to his own life, to his own liberty, to his own property and to the pursuit of his own happiness. Without property rights, no other rights are possible.

My basic sense of it has always been to get people to understand that in the long run they themselves are the only protection they have against violence or injustice.

The purpose of protecting the life of our Nation and preserving the liberty of our citizens is to pursue the happiness of our people. Our success in that pursuit is the test of our success as a Nation.

To minimize suffering and to maximize security were natural and proper ends of society and Caesar. But then they became the only ends, somehow, and the only basis of law — a perversion. Inevitably, then, in seeking only them, we found only their opposites: maximum suffering and minimum security.

[T]here is only one purpose to which a whole society can be directed by a deliberate plan. That purpose is war, and there is no other.

The aim of protection, in short, is to prevent the bringing into a country of things in themselves useful and valuable, in order to compel the making of such things. But what all mankind in the individual affairs of every-day life, regard as to be desired is not the making of things, but the possession of things.

Let us be clear at the outset that the liberty of individuals to carry on their business should not be abrogated unless the larger interests of the many are concerned. It is the purpose of government to see that not only the legitimate interests of the few are protected but that the welfare and rights of the many are conserved. These are the principals which must be remembered in any consideration of this question. This, I take it, is sound government-not politics.

Power has only one duty — to secure the social welfare of the people.

The common run of moralists complain that man is moved by his private self-interest: would to heaven it were so! Private interest is a self-centered principle of action, but at the same time restricted, reasonable and incapable of giving rise to unlimited evils. Whereas, on the other hand, the law of all activities governing social life, except in the case of primitive communities, is that here one sacrifices human life — in himself and in others — to things which are only means to a better way of living. This sacrifice takes on various forms, but it all comes back to the question of power. Power, by definition, is only a means; or to put it better, to possess a power is simply to possess means of action which exceed the very limited force that a single individual has at his disposal. But power-seeking, owing to its essential incapacity to seize hold of its object, rules out all consideration of an end, and finally comes, through an inevitable reversal, to take the place of all ends. It is this reversal of the relationship between means and end, it is this fundamental folly that accounts for all that is senseless and bloody right through history. Human history is simply the history of the servitude which makes men — oppressed and oppressors alike — the plaything of the instruments of domination they themselves have manufactured, and thus reduces living humanity to being the chattel of inanimate chattels.

Ultimately, the only power to which man should aspire is that which he exercises over himself.

For we are given power not to advance our own purposes, nor to make a great show in the world, nor a name. There is but one just use of power, and it is to serve people. Help us to remember it, Lord.

From a political point of view, there is but one principle, the sovereignty of man over himself. This sovereignty of myself over myself is called Liberty
