“It is only with this prelude that the Declaration of 1776 proclaims the right to revolution. The people do not have an indiscriminate or uncontrolled right to establish or to abolish governments. They have a right to abolish only those governments that become "destructive of these ends". "These ends" refers to the security of equal natural rights. It is only for the sake of security of these rights that legitimate governments are instituted, or that governments may be altered or abolished. And governments are legitimate only insofar as their "just powers" are derived "from the consent of the governed". All of the foregoing is omitted from South Carolina's declaration, for obvious reasons. In no sense could it have been said that the slaves in South Carolina were governed by powers derived from their consent. Nor could it be said that South Carolina was separating itself from the government of the Union because that government had become destructive of the ends for which it was established. South Carolina in 1860 had an entirely different idea of what the ends of government ought to be from that of 1776 or 1787. That difference can be summed up in the difference between holding slavery to be an evil, if possibly a necessary evil, and holding it to be a positive good.”

Context: It may now be easily seen how great the difference is between the institution of government, as understood by Paine and the Declaration of Independence, and the institution of the State. … The nature and intention of government … are social. Based on the idea of natural rights, government secures those rights to the individual by strictly negative intervention, making justice costless and easy of access; and beyond that it does not go. The State, on the other hand, both in its genesis and by its primary intention, is purely anti-social. It is not based on the idea of natural rights, but on the idea that the individual has no rights except those that the State may provisionally grant him. It has always made justice costly and difficult of access, and has invariably held itself above justice and common morality whenever it could advantage itself by so doing.

Context: The equal rights of man, and the happiness of every individual, are now acknowledged to be the only legitimate objects of government. Modern times have the signal advantage, too, of having discovered the only device by which these rights can be secured, to wit: government by the people, acting not in person, but by representatives chosen by themselves, that is to say; by every man of ripe years and sane mind, who either contributes by his purse or person to the support of his country.
