They that have instituted a commonwealth by covenant cannot make a new covenant contrary thereto without permission of the sovereign, since this is a breaking of their covenant with each other. On his part there is no covenant, so that breach of covenant by him cannot be pleaded as warranting abrogation of the covenant made. The sovereign cannot do the subjects injustice because, since he has their authority, what he does to them is done by their own will; so also they cannot punish him. Since the sovereign was instituted for peace and defence, he controls the means to war and peace, and judges of opinions as conducing to peace or endangering it. He prescribes the rules of property, since in the state of nature there is no property; he has the right of judicature; of making war and peace with other commonwealths; of choosing all counsellors in peace and war; of rewarding and punishing, according to the law he has made, and of bestowing honour. Nay, if he grants away any of these powers the grant is null. The sovereignty may be in one man, or in a limited assembly, or in an assembly of all--monarchy, aristocracy, democracy; these three forms only, though when they are misliked they are called other names. In any case, the power of the sovereign is absolute, whether a monarch or an assembly. He is the representative of the commonwealth, not deputies who may be chosen to tender petitions. The three forms differ not in the power of the sovereign, but in their advantageousness. In monarchy, the private interest of the sovereign must coincide with that of the commonwealth as a whole; much more so than in aristocracy or democracy. An assembly cannot receive counsel secretly; a monarchy has the benefit of a single will instead of conflicting wills. There is no government by a mixture of the types, _e.g._, an elective "king" is not sovereign, but a minister; and within his province a Roman pro-consul was an absolute monarch. Men submit themselves to an instituted sovereign, for fear of each other; to an acquired sovereignty, for fear of the sovereign. Acquired sovereignty or dominion is either by generation (paternal) or by conquest. A family, however, does not amount to a commonwealth, unless it be so great that it may not be subdued but by war. Acquired sovereignty is absolute, for the same reasons as instituted sovereignty. _III.--The Natural Commonwealth_ Liberty is absence of impediments to motion. It is consistent with fear, also with necessity; for a voluntary act is yet necessary as having a cause which is a link in a chain of causes up to the First Cause, which is God. But men have created artificial impediments or bonds called laws. The liberty of the subject lies only in such things as the sovereign has pretermitted, for he hath power to regulate all, even life and death, at his own will. The liberty praised in Rome and Athens was the liberty of the commonwealth as against other commonwealths.
