Thomas Hobbes, Leviathan (1651)
ch. 13: In such condition, there is no place for Industry; because the fruit thereof is uncertain: and consequently no Culture of the Earth; no Navigation, nor use of the commodities that may be imported by Sea; no commodious Building; no Instruments of moving, and removing such things as require much force; no Knowledge of the face of the Earth; no account of Time; no Arts; no Letters; no Society; and which is worst of all, continuall feare, and danger of violent death; And the life of man, solitary, poore, nasty, brutish, and short.
ch. 14: And because the condition of Man, (as hath been declared in the precedent Chapter) is a condition of Warre of every one against every one; ... It followeth, that in such a condition, every man has a Right to every thing; even to one anothers body. And therefore, as long as this naturall Right of every man to every thing endureth, there can be no security to any man, (how strong or wise soever he be,) of living out the time, which Nature ordinarily alloweth men to live. And consequently it is a precept, or generall rule of Reason, That every man, ought to endeavour Peace, as farre as he has hope of obtaining it; and when he cannot obtain it, he may seek, and use, all helps, and advantages of Warre.
ch. 17: The only way to erect such a Common Power, as may be able to defend them from the invasion of Forraigners, and the injuries of one another, and thereby to secure them in such sort, as that by their owne industrie, and by the fruites of the Earth, they may nourish themselves and live contentedly; is, to conferre all their power and strength upon one Man, or upon one Assembly of men, that may reduce all their Wills, by plurality of voices, unto one Will: ... This is more than Consent, or Concord; it is a reall Unitie of them all, in one and the same Person, made by Covenant of every man with every man, in such manner, as if every man should say to every man, I Authorise and give up my Right of Governing my selfe, to this Man, or to this Assembly of men, on this condition, that thou give up thy Right to him, and Authorise all his Actions in like manner. This done, the Multitude so united one Person, is called a Common-wealth, in latine Civitas. This is the Generation of that great Leviathan, or rather (to speake more reverently) of that Mortall God, to which wee owe under the Immortall God, our peace and defence.
ch. 18: For these are incommunicable, and inseparable. The Power to coyn Mony; to dispose of the estate and persons of Infant heires; to have praeemption in Markets; and in all other Statute Praerogatives, may be transferred by the Soveraign; and yet the Power to protect his Subjects be retained. But if he transferre the Militia, he retains the Judicature in vain, for want of execution of the Lawes: Or if he grant away the Power of raising Mony; the Militia is in vain: or if he give away the government of Doctrines, men will be frighted into rebellion with the feare of Spirits. And so if we consider any one of the said Rights, we shall presently see, that the holding of all the rest, will produce no effect, in the conservation of Peace and Justice, the end for which all Common-wealths are Instituted. And this division is it, whereof it is said, A Kingdome divided in itself cannot stand: for unless this division precede, division into opposite Armies can never happen. If there had not first been an opinion received of the greatest part of England, that these Powers were divided between the King, and the Lords, and the House of Commons, the people had never been divided, and fallen into this Civill Warre.
John Locke, Second Treatise on Government (1690)
Sec. 6: But though this be a state of liberty, yet it is not a state of licence: though man in that state have an uncontroulable liberty to dispose of his person or possessions, yet he has not liberty to destroy himself, or so much as any creature in his possession , but where some nobler use than its bare preservation calls for it. The state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind, who will but consult it, that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions:
Sec. 95: Men being, as has been said, by nature, all free, equal, and independent, no one can be put out of this estate, and subjected to the political power of another, without his own consent. The only way whereby any one divests himself of his natural liberty, and puts on the bonds of civil society, is by agreeing with other men to join and unite into a community for their comfortable, safe, and peaceable living one amongst another, in a secure enjoyment of their properties, and a greater security against any, that are not of it.
Sec. 222: The reason why men enter into society, is the preservation of their property; and the end why they chuse and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society, to limit the power, and moderate the dominion, of every part and member of the society: for since it can never be supposed to be the will of the society, that the legislative should have a power to destroy that which every one designs to secure, but entering into society, and for which the people submitted themselves to legislators of their own making; whenever the legislators endeavour to take away, and destroy the property of the people, or to reduce them to slavery under arbitrary power, they put themselves into a state of war with the people, who are thereupon absolved from any farther obedience, and are left to the common refuge, which God hath provided for all men, against force and violence. Whensoever therefore the legislative shall transgress this fundamental rule of society; and either by ambition, fear, folly or corruption, endeavour to grasp themselves, or put into the hands of any other, an absolute power over the lives, liberties, and estates fo the people; by this breach of trust they forfeit the power the people had put into their hands for quite contrary ends, and it devolves to the people, who have a right to resume their original liberty, and, by the establishment of a new legislative, (such as they shall think fit) provide for their own safety and security, which is the end for which they are in society.
Rousseau, Discourse on the Origin of Inequality (1751)
Above all, let us not conclude, with Hobbes, that because man has no idea of goodness, he must be naturally wicked; that he is vicious because he does not know virtue; that he always refuses to do his fellow-creatures services which he does not think they have a right to demand; or that by virtue of the right he justly claims to all he needs, he foolishly imagines himself the sole proprietor of the whole universe.
The first man who, having enclosed a piece of ground, bethought himself of saying “This is mine,” and found people simple enough to believe him, was the real founder of civil society.
In a word, there arose rivalry and competition on the one hand, and conflicting interests on the other, together with a secret desire on both of profiting at the expense of others. All these evils were the first effects of property, and the inseparable attendants of growing inequality.
The destruction of equality was attended by the most terrible disorders. Usurpations by the rich, robbery by the poor, and the unbridled passions of both, suppressed the cries of natural compassion and the still feeble voice of justice, and filled men with avarice, ambition, and vice. Between the title of the strongest and that of the first occupier, there arose perpetual conflicts, which never ended but in battles and bloodshed. The new-born state of society thus gave rise to a horrible state of war; men thus harassed and depraved were no longer capable of retracing their steps or renouncing the fatal acquisitions they had made, but, laboring by the abuse of the faculties which do them honor, merely to their own confusion, brought themselves to the brink of ruin.
The passage from the state of nature to the civil state produces a very remarkable change in man, by substituting justice for instinct in his conduct, and giving his actions the morality they had formerly lacked. Then only, when the voice of duty takes that place of physical impulses and right of appetite, does man, who so far had considered only himself, find that he is forced to act on different principles, and to consult his reason before listening to his inclinations. Although, in this state, he deprives himself of some advantages which he got from nature, he gains in return others so great, his faculties are so stimulated and developed, his ideas so extended, his feelings so ennobled, and his whole soul so uplifted, that, did not the abuses of this new condition often degrade him below that which he left, he would be bound to bless continually the happy moment which took him from it for ever, and, instead of stupid and unimaginative animal, made him an intelligent being and a man.
Let us draw up the whole account in terms easily commensurable. What man loses by the social contract is his natural liberty and an unlimited right to everything he tries to get and succeeds in getting; what he gains is civil liberty and the proprietorship of all he possesses.
