Second Treatise of Government, first published in 1690, was the crucial influence on the Declaration of Independence; indeed the theoretical core of the Declaration is entirely Lockean, and even whole passages are borrowed (see, e.g. section #225). Yet, the Second Treatise is rarely read in school and hardly ever mentioned on July 4, the day on which this philosopher’s ideals were realized in the American secession from Britain. Here are excerpts from The Second Treatise of Government:
Chapter IV Of Slavery
21. The natural liberty of man is to be free from any superior power on earth, and not to be under the will or legislative authority of man, but to have only the law of Nature for his rule. The liberty of man in society is to be under no other legislative power but that established by consent in the commonwealth, nor under the dominion of any will, or restraint of any law, but what that legislative shall enact according to the trust put in it. Freedom, then, is not what Sir Robert Filmer tells us: "A liberty for every one to do what he lists, to live as he pleases, and not to be tied by any laws"; but freedom of men under government is to have a standing rule to live by, common to every one of that society, and made by the legislative power erected in it. A liberty to follow my own will in all things where that rule prescribes not, not to be subject to the inconstant, uncertain, unknown, arbitrary will of another man, as freedom of nature is to be under no other restraint but the law of Nature.
22. This freedom from absolute, arbitrary power is so necessary to, and closely joined with, a man's preservation, that he cannot part with it but by what forfeits his preservation and life together. For a man, not having the power of his own life, cannot by compact or his own consent enslave himself to any one, nor put himself under the absolute, arbitrary power of another to take away his life when he pleases. Nobody can give more power than he has himself, and he that cannot take away his own life cannot give another power over it. Indeed, having by his fault forfeited his own life by some act that deserves death, he to whom he has forfeited it may, when he has him in his power, delay to take it, and make use of him to his own service; and he does him no injury by it. For, whenever he finds the hardship of his slavery outweigh the value of his life, it is in his power, by resisting the will of his master, to draw on himself the death he desires.
23. This is the perfect condition of slavery, which is nothing else but the state of war continued between a lawful conqueror and a captive, for if once compact enter between them, and make an agreement for a limited power on the one side, and obedience on the other, the state of war and slavery ceases as long as the compact endures; for, as has been said, no man can by agreement pass over to another that which he hath not in himself- a power over his own life.
Chapter V Of Property
24. Whether we consider natural reason, which tells us that men, being once born, have a right to their preservation, and consequently to meat and drink and such other things as Nature affords for their subsistence, or "revelation," which gives us an account of those grants God made of the world to Adam, and to Noah and his sons, it is very clear that God, as King David says (Psalm 115. 16), "has given the earth to the children of men," given it to mankind in common. But, this being supposed, it seems to some a very great difficulty how any one should ever come to have a property in anything, I will not content myself to answer, that, if it be difficult to make out "property" upon a supposition that God gave the world to Adam and his posterity in common, it is impossible that any man but one universal monarch should have any "property" upon a supposition that God gave the world to Adam and his heirs in succession, exclusive of all the rest of his posterity; but I shall endeavour to show how men might come to have a property in several parts of that which God gave to mankind in common, and that without any express compact of all the commoners.
25. God, who hath given the world to men in common, hath also given them reason to make use of it to the best advantage of life and convenience. The earth and all that is therein is given to men for the support and comfort of their being. And though all the fruits it naturally produces, and beasts it feeds, belong to mankind in common, as they are produced by the spontaneous hand of Nature, and nobody has originally a private dominion exclusive of the rest of mankind in any of them, as they are thus in their natural state, yet being given for the use of men, there must of necessity be a means to appropriate them some way or other before they can be of any use, or at all beneficial, to any particular men. The fruit or venison which nourishes the wild Indian, who knows no enclosure, and is still a tenant in common, must be his, and so his- i.e., a part of him, that another can no longer have any right to it before it can do him any good for the support of his life.
26. Though the earth and all inferior creatures be common to all men, yet every man has a "property" in his own "person." This nobody has any right to but himself. The "labour" of his body and the "work" of his hands, we may say, are properly his. Whatsoever, then, he removes out of the state that Nature hath provided and left it in, he hath mixed his labour with it, and joined to it something that is his own, and thereby makes it his property. It being by him removed from the common state Nature placed it in, it hath by this labour something annexed to it that excludes the common right of other men. For this "labour" being the unquestionable property of the labourer, no man but he can have a right to what that is once joined to, at least where there is enough, and as good left in common for others.
Chapter XVIII Of Tyranny
199. As usurpation is the exercise of power which another hath a right to, so tyranny is the exercise of power beyond right, which nobody can have a right to; and this is making use of the power any one has in his hands, not for the good of those who are under it, but for his own private, separate advantage. When the governor, however entitled, makes not the law, but his will, the rule, and his commands and actions are not directed to the preservation of the properties of his people, but the satisfaction of his own ambition, revenge, covetousness, or any other irregular passion.
202. Wherever law ends, tyranny begins, if the law be transgressed to another's harm; and whosoever in authority exceeds the power given him by the law, and makes use of the force he has under his command to compass that upon the subject which the law allows not, ceases in that to be a magistrate, and acting without authority may be opposed, as any other man who by force invades the right of another. This is acknowledged in subordinate magistrates. He that hath authority to seize my person in the street may be opposed as a thief and a robber if he endeavours to break into my house to execute a writ, notwithstanding that I know he has such a warrant and such a legal authority as will empower him to arrest me abroad. And why this should not hold in the highest, as well as in the most inferior magistrate, I would gladly be informed. Is it reasonable that the eldest brother, because he has the greatest part of his father's estate, should thereby have a right to take away any of his younger brothers' portions? Or that a rich man, who possessed a whole country, should from thence have a right to seize, when he pleased, the cottage and garden of his poor neighbour? The being rightfully possessed of great power and riches, exceedingly beyond the greatest part of the sons of Adam, is so far from being an excuse, much less a reason for rapine and oppression, which the endamaging another without authority is, that it is a great aggravation of it. For exceeding the bounds of authority is no more a right in a great than a petty officer, no more justifiable in a king than a constable. But so much the worse in him as that he has more trust put in him, is supposed, from the advantage of education and counsellors, to have better knowledge and less reason to do it, having already a greater share than the rest of his brethren.
Chapter XIX Of the Dissolution of Government
222. The reason why men enter into society is the preservation of their property; and the end while they choose and authorise a legislative is that there may be laws made, and rules set, as guards and fences to the properties of all 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 by 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 of 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.
223. To this, perhaps, it will be said that the people being ignorant and always discontented, to lay the foundation of government in the unsteady opinion and uncertain humour of the people, is to expose it to certain ruin; and no government will be able long to subsist if the people may set up a new legislative whenever they take offence at the old one. To this I answer, quite the contrary. People are not so easily got out of their old forms as some are apt to suggest. They are hardly to be prevailed with to amend the acknowledged faults in the frame they have been accustomed to. And if there be any original defects, or adventitious ones introduced by time or corruption, it is not an easy thing to get them changed, even when all the world sees there is an opportunity for it. This slowness and aversion in the people to quit their old constitutions has in the many revolutions [that] have been seen in this kingdom, in this and former ages, still kept us to, or after some interval of fruitless attempts, still brought us back again to, our old legislative of king, lords and commons; and whatever provocations have made the crown be taken from some of our princes' heads, they never carried the people so far as to place it in another line.
224. But it will be said this hypothesis lays a ferment for frequent rebellion. To which I answer:
First: no more than any other hypothesis. For when the people are made miserable, and find themselves exposed to the ill usage of arbitrary power, cry up their governors as much as you will for sons of Jupiter, let them be sacred and divine, descended or authorised from Heaven; give them out for whom or what you please, the same will happen. The people generally ill treated, and contrary to right, will be ready upon any occasion to ease themselves of a burden that sits heavy upon them. They will wish and seek for the opportunity, which in the change, weakness, and accidents of human affairs, seldom delays long to offer itself He must have lived but a little while in the world, who has not seen examples of this in his time; and he must have read very little who cannot produce examples of it in all sorts of governments in the world.
225. Secondly: I answer, such revolutions happen not upon every little mismanagement in public affairs. Great mistakes in the ruling part, many wrong and inconvenient laws, and all the slips of human frailty will be borne by the people without mutiny or murmur. But if a long train of abuses, prevarications, and artifices, all tending the same way, make the design visible to the people, and they cannot but feel what they lie under, and see whither they are going, it is not to be wondered that they should then rouse themselves, and endeavour to put the rule into such hands which may secure to them the ends for which government was at first erected, and without which, ancient names and specious forms are so far from being better, that they are much worse than the state of Nature or pure anarchy; the inconveniencies being all as great and as near, but the remedy farther off and more difficult.
226. Thirdly: I answer, that this power in the people of providing for their safety anew by a new legislative when their legislators have acted contrary to their trust by invading their property, is the best fence against rebellion, and the probable means to hinder it. For rebellion being an opposition, not to persons, but authority, which is founded only in the constitutions and laws of the government: those, whoever they be, who, by force, break through, and, by force, justify their violation of them, are truly and properly rebels. For when men, by entering into society and civil government, have excluded force, and introduced laws for the preservation of property, peace, and unity amongst themselves, those who set up force again in opposition to the laws, do rebellare- that is, bring back again the state of war, and are properly rebels, which they who are in power, by the pretence they have to authority, the temptation of force they have in their hands, and the flattery of those about them being likeliest to do, the proper way to prevent the evil is to show them the danger and injustice of it who are under the greatest temptation to run into it.
