The reason why men enter into society is the preservation of their property; and the end while they choose and authorize 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 everyone designs to secure by entering into society, and for which the people submitted themselves to legislators of their own making: whenever the legislators endeavor 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, endeavor 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.
