Being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.

As usurpation is the exercise of power, which another hath a right to; so tyranny is the exercise of power beyond right, which no body 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 intitled, 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.

Right and conveniency went together; for as a man had a right to all he could employ his labour upon, so he had no temptation to labour for more than he could make use of. This left no room for controversy about the title, nor for encroachment on the right of others ; what portion a man carved to himself was easily seen: and it was useless, as well as dishonest, to carve himself too much, or take more than he needed.

Government has no other end than the preservation of property.
