John Locke, Second Treatise on Government (1690)
To understand political power right, and derive it from its original, we must consider, what state all men are naturally in, and that is, a state of perfect freedom to order their actions, and dispose of their possessions and persons, as they think fit, within the bounds of the law of nature, without asking leave, or depending upon the will of any other man.
A state also of equality, wherein all the power and jurisdiction is reciprocal, no one having more than another; there being nothing more evident, than that creatures of the same species and rank, promiscuously born to all the same advantages of nature, and the use of the same faculties, should also be equal one amongst another without subordination or subjection, unless the lord and master of them all should, by any manifest declaration of his will, set one above another, and confer on him, by an evident and clear appointment, an undoubted right to dominion and sovereignty. . .
. . . But because no political society can be, nor subsist, without having in itself the power to preserve the property, and in order thereunto, punish the offences of all those of that society; there, and there only is political society, where every one of the members hath quitted this natural power, resigned it up into the hands of the community in all cases that exclude him not from appealing for protection to the law established by it. And thus all private judgment of every particular member being excluded, the community comes to be umpire, by settled standing rules, indifferent, and the same to all parties; and by men having authority from the community, for the execution of those rules, decides all the differences that may happen between any members of that society concerning any matter of right; and punishes those offences which any member hath committed against the society, with such penalties as the law has established: whereby it is easy to discern, who are, and who are not, in political society together. Those who are united into one body, and have a common established law and judicature to appeal to, with authority to decide controversies between them, and punish offenders, are in civil society one with another: but those who have no such common appeal, I mean on earth, are still in the state of nature, each being, where there is no other, judge for himself, and executioner; which is, as I have before showed it, the perfect state of nature.
And thus the common-wealth comes by a power to set down what punishment shall belong to the several transgressions which they think worthy of it, committed amongst the members of that society, (which is the power of making laws) as well as it has the power to punish any injury done unto any of its members, by any one that is not of it, (which is the power of war and peace;) and all this for the preservation of the property of all the members of that society, as far as is possible. But though every man who has entered into civil society, and is become a member of any commonwealth, has thereby quitted his power to punish offences, against the law of nature, in prosecution of his own private judgment, yet with the judgment of offences, which he has given up to the legislative in all cases, where he can appeal to the magistrate, he has given a right to the common-wealth to employ his force, for the execution of the judgments of the common-wealth, whenever he shall be called to it; which indeed are his own judgments, they being made by himself, or his representative. And herein we have the original of the legislative and executive power of civil society, which is to judge by standing laws, how far offences are to be punished, when committed within the common-wealth; and also to determine, by occasional judgments founded on the present circumstances of the fact, how far injuries from without are to be vindicated; and in both these to employ all the force of all the members, when there shall be need.
Hence it is evident, that absolute monarchy, which by some men is counted the only government in the world, is indeed inconsistent with civil society, and so can be no form of civil-government at all: for the end of civil society, being to avoid, and remedy those inconveniencies of the state of nature, which necessarily follow from every man's being judge in his own case, by setting up a known authority, to which every one of that society may appeal upon any injury received, or controversy that may arise, and which every one of the society ought to obey; where-ever any persons are, who have not such an authority to appeal to, for the decision of any difference between them, there those persons are still in the state of nature; and so is every absolute prince, in respect of those who are under his dominion.
For he being supposed to have all, both legislative and executive power in himself alone, there is no judge to be found, no appeal lies open to any one, who may fairly, and indifferently, and with authority decide, and from whose decision relief and redress may be expected of any injury or inconviency, that may be suffered from the prince, or by his order. . . .
There is one more way whereby such a government may be dissolved, and that is when he who has the supreme executive power neglects and abandons that charge, so that the laws already made can no longer be put in execution. This is demonstrably to reduce all to anarchy, and so effectually to dissolve the government. For laws not being made for themselves, but to be by their execution the bonds of the society, to keep every part of the body politic in its due place and function, when that totally ceases, the government visibly ceases, and the people become a confused multitude, without order or connection. . .
In these and the like cases, when the government is dissolved, the people are at liberty to provide for themselves, by erecting a new legislative, differing from the other by the change of persons or form. . .
