In the second place it comes to be considered that subjects are so far dependent, not on themselves but on the commonwealth, as they fear its power or threats, or as they love the civil state. Whence it follows, that such things, as no one can be induced to do by rewards or threats, do not fall within the rights of the commonwealth. For instance, by reason of his faculty of judgment, it is in no man's power to believe. For by what rewards or threats can a man be brought to believe that the whole is not greater than its part, or that God does not exist, or that that is an infinite being, which he sees to be finite, or, generally, anything contrary to his sense or thought? So, too, by what rewards or threats can a man be brought to love one whom he hates, or to hate one whom he loves? And to this head must likewise be referred such things as are so abhorrent to human nature, that it regards them as actually worse than any evil, as that a man should be witness against himself, or torture himself, or kill his parents, or not strive to avoid death, and the like, to which no one can be induced by rewards or threats. But if we still choose to say that the commonwealth has the right or authority to order such things, we can conceive of it in no other sense than that in which one might say that a man has the right to be mad or delirious. For what but a delirious fancy would such a right be, as could bind no one? And here I am speaking expressly of such things as cannot be subject to the right of a commonwealth and are abhorrent to human nature in general. For the fact that a fool or madman can by no rewards or threats be induced to execute orders, or that this or that person, because he is attached to this or that religion, judges the laws of a dominion worse than any possible evil, in no wise makes void the laws of the commonwealth, since by them most of the citizens are restrained. And so, as those who are without fear or hope are so far independent, they are, therefore, enemies of the dominion, and may lawfully be coerced by force.
Thirdly, and lastly, it comes to be considered that those things are not so much within the commonwealth's right, which cause indignation in the majority. For it is certain, that by the guidance of Nature men conspire together, either through common fear, or with the desire to avenge some common hurt; and as the right of the commonwealth is determined by the common power of the multitude, it is certain that the power and right of the commonwealth are so far diminished, as it gives occasion for many to conspire together. There are certainly some subjects of fear for a commonwealth, and as every separate citizen or in the state of Nature every man, so a commonwealth is the less independent, the greater reason it has to fear. So much for the right of supreme authorities over subjects. Now before I treat of the right of the said authorities as against others, we had better resolve a question commonly mooted about religion.
For it may be objected to us, Do not the civil state, and the obedience of subjects, such as we have shown is required in the civil state, do away with religion, whereby we are bound to worship God? But if we consider the matter, as it really is, we shall find nothing that can suggest a scruple. For the mind, so far as it makes use of reason, is dependent, not on the supreme authorities, but on itself. And so the true knowledge and the love of God cannot be subject to the dominion of any, nor yet can charity towards one's neighbor. And if we further reflect that the highest exercise of charity is that which aims at keeping peace and joining in unity, we shall not doubt that he does his duty, who helps every one, so far as the commonwealth's laws, that is, so far as unity and quiet allow. As for external rites, it is certain, that they can do no good or harm at all in respect of the true knowledge of God, and the love which necessarily results from it; and so they ought not to be held of such importance, that it should be thought worth while on their account to disturb public peace and quiet. Moreover, it is certain that I am not a champion of religion by the law of Nature, that is, by the divine decree. For I have no authority, as once the disciples of Christ had, to cast out unclean spirits and work miracles; which authority is yet so necessary to the propagating of religion in places where it is forbidden, that without it one not only, as they say, wastes one's time[37] and trouble, but causes besides very many inconveniences, whereof all ages have seen most mournful examples. Every one therefore, wherever he may be, can worship God with true religion, and mind his own business, which is the duty of a private man. But the care of propagating religion should be left to God, or the supreme authorities, upon whom alone falls the charge of affairs of state. But I return to my subject.
After explaining the right of supreme authorities over citizens and the duty of subjects, it remains to consider the right of such authorities against the world at large, which is now easily intelligible from what has been said. For since the right of the supreme authorities is nothing else but simple natural right, it follows that two dominions stand towards each other in the same relation as do two men in the state of Nature, with this exception, that a commonwealth can provide against being oppressed by another; which a man in the state of Nature cannot do, seeing that he is overcome daily by sleep, often by disease or mental infirmity, and in the end by old age, and is besides liable to other inconveniences, from which a commonwealth can secure itself.
A commonwealth, then, is so far independent, as it can plan and provide against oppression by another, and so far dependent on another commonwealth, as it fears that other's power, or is hindered by it from executing its own wishes, or, lastly, as it needs its help for its own preservation or increase. For we cannot at all doubt, that if two commonwealths are willing to offer each other mutual help, both together are more powerful, and therefore have more right, than either alone.
But this will be more clearly intelligible if we reflect that two commonwealths are naturally enemies. For men in the state of Nature are enemies. Those, then, who stand outside a commonwealth, and retain their natural rights, continue enemies. Accordingly, if one commonwealth wishes to make war on another and employ extreme measures to make that other dependent on itself, it may lawfully make the attempt, since it needs but the bare will of the commonwealth for war to be waged. But concerning peace it can decide nothing, save with the concurrence of another commonwealth's will. When it follows that laws of war regard every commonwealth by itself, but laws of peace regard not one, but at the least two commonwealths, which are therefore called "contracting parties."
This "contract" remains so long unmoved as the motive for entering into it, that is, fear of hurt or hope of gain, subsists. But take away from either commonwealth this hope or fear, and it is left independent, and the link, whereby the commonwealths were mutually bound, breaks of itself. And therefore every commonwealth has the right to break its contract, whenever it chooses, and cannot be said to act treacherously or perfidiously in breaking its word, as soon as the motive of hope or fear is removed. For every contracting party was on equal terms in this respect, that whichever could first free itself of fear should be independent, and make use of its independence after its own mind; and, besides, no one makes a contract respecting the future, but on the hypothesis of certain precedent circumstances. But when these circumstances change, the reason of policy applicable to the whole position changes with them; and therefore every one of the contracting commonwealths retains the right of consulting its own interest, and consequently endeavors, as far as possible, to be free from fear and thereby independent, and to prevent another from coming out of the contract with greater power. If then a commonwealth complains that it has been deceived, it cannot properly blame the bad faith of another contracting commonwealth, but only its own folly in having entrusted its own welfare to another party, that was independent, and had for its highest law the welfare of its own dominion.
To commonwealths, which have contracted a treaty of peace, it belongs to decide the questions which may be mooted about the terms or rules of peace, whereby they have mutually bound themselves, inasmuch as laws of peace regard not one commonwealth, but the commonwealths which contract taken together. But if they cannot agree together about the conditions, they by that very fact return to a state of war.
The more commonwealths there are, that have contracted a joint treaty of peace, the less each of them by itself is an object of fear to the remainder, or the less it has the authority to make war. But it is so much the more bound to observe the conditions of peace; that is, the less independent, and the more bound to accommodate itself to the general will of the contracting parties.
But the good faith, inculcated by sound reason and religion, is not hereby made void; for neither reason nor Scripture teaches one to keep one's word in every case. For if I have promised a man, for instance, to keep safe a sum of money he has secretly deposited with me, I am not bound to keep my word, from the time that I know or believe the deposit to have been stolen, but I shall act more rightly in endeavoring to restore it to its owners. So likewise, if the supreme authority has promised another to do something, which subsequently occasion or reason shows or seems to show is contrary to the welfare of its subjects, it is surely bound to break its word. As then Scripture only teaches us to keep our word in general, and leaves to every individual's judgment the special cases of exception, it teaches nothing repugnant to what we have just proved.
