Natural law, natural justice, being a principle that is naturally applicable and adequate to the rightful settlement of every possible controversy that can arise among men; being, too, the only standard by which any controversy whatever, between man and man, can be rightfully settled; being a principle whose protection every man demands for himself, whether he is willing to accord it to others, or not; being also an immutable principle, one that is always and everywhere the same, in all ages and nations; being self-evidently necessary in all times and places; being so entirely impartial and equitable towards all; so indispensable to the peace of mankind everywhere; so vital to the safety and welfare of every human being; being, too, so easily learned, so generally known, and so easily maintained by such voluntary associations as all honest men can readily and rightfully form for that purpose—being such a principle as this, these questions arise, viz.: Why is it that it does not universally, or well nigh universally, prevail? Why is it that it has not, ages ago, been established throughout the world as the one only law that any man, or all men, could rightfully be compelled to obey? Why is it that any human being ever conceived that anything so self-evidently superfluous, false, absurd, and atrocious as all legislation necessarily must be, could be of any use to mankind, or have any place in human affairs?

What, then, is legislation? It is an assumption by one man, or body of men, of absolute, irresponsible dominion over all other men whom they can subject to their power. It is the assumption by one man, or body of men, of a right to subject all other men to their will and their service. It is the assumption by one man, or body of men, of a right to abolish outright all the natural rights, all the natural liberty of all other men; to make all other men their slaves; to arbitrarily dictate to all other men what they may, and may not, do; what they may, and may not, have; what they may, and may not, be. It is, in short, the assumption of a right to banish the principle of human rights, the principle of justice itself, from off the earth, and set up their own personal will, pleasure, and interest in its place. All this, and nothing less, is involved in the very idea that there can be any such thing as human legislation that is obligatory upon those upon whom it is imposed.
