So much of what needs to be said on this subject has already been said, and said long ago. I'll just leave this here:
What is law? What ought it to be? What is its domain? What are its limits? Where, in fact, does the prerogative of the legislator stop? I have no hesitation in answering, Law is common force organized to prevent injustice;—in short, Law is Justice. It is not true that the legislator has absolute power over our persons and property, since they pre-exist, and his work is only to secure them from injury. It is not true that the mission of the law is to regulate our consciences, our ideas, our will, our education, our sentiments, our works, our exchanges, our gifts, our enjoyments. Its mission is to prevent the rights of one from interfering with those of another, in any one of these things.
Law, because it has force for its necessary sanction, can only have the domain of force, which is justice. And as every individual has a right to have recourse to force only in cases of lawful defense, so collective force, so which is only the union of individual forces, cannot be rationally used for any other end. The law, then, is solely the organization of individual rights that existed before law.

Legal plunder has two roots: one of them, as we have already seen, is in human greed; the other is in misconceived philanthropy. Before I proceed, I think I ought to explain myself upon the word plunder. I do not take it, as it often is taken, in a vague, undefined, relative, or metaphorical sense. I use it in its scientific acceptation, and as expressing the opposite idea to property. When a portion of wealth passes out of the hands of him who has acquired it, without his consent, and without compensation, to him who has not created it, whether by force or by artifice, I say that property is violated, that plunder is perpetrated. I say that this is exactly what the law ought to repress always and everywhere. If the law itself performs the action it ought to repress, I say that plunder is still perpetrated, and even, in a social point of view, under aggravated circumstances. In this case, however, he who profits from the plunder is not responsible for it; it is the law, the lawgiver, society itself, and this is where the political danger lies.
It is to be regretted that there is something offensive in the word. I have sought in vain for another, for I would not wish at any time, and especially just now, to add an irritating word to our disagreements; therefore, whether I am believed or not, I declare that I do not mean to impugn the intentions nor the morality of anybody. I am attacking an idea that I believe to be false—a system that appears to me to be unjust; and this is so independent of intentions, that each of us profits by it without wishing it, and suffers from it without being aware of the cause.
Any person must write under the influence of party spirit or of fear, who would call into question the sincerity of protectionism, of socialism, and even of communism, which are one and the same plant, in three different periods of its growth. All that can be said is, that plunder is more visible by its partiality in protectionism, 3 and by its universality in communism; whence it follows that, of the three systems, socialism is still the most vague, the most undefined, and consequently the most sincere. Be that as it may, to conclude that legal plunder has one of its roots in misconceived philanthropy, is evidently to put intentions out of the question.
With this understanding, let us examine the value, the origin, and the tendency of this popular aspiration, which pretends to realize the general good by general plunder. The Socialists say, since the law organizes justice, why should it not organize labor, instruction, and religion? Why? Because it could not organize labor, instruction, and religion, without disorganizing justice. For remember, that law is force, and that consequently the domain of the law cannot properly extend beyond the domain of force.
