That there is great Reason to live up to Justice.
JƲstice having been established by a common Agree∣ment, every one ought to think that he is born and admitted into the Society whereof he is a Member, upon this Condition, either express or understood, That he shall do wrong to no Man, nor no Man to him; and thus we must either keep to this Agreement, or depart out of the Society, seeing that he is suffered there but upon the same Condition that he was admitted: From whence it follows, that as naturally he don't desire to be evilly dealt withal, he ought not to deal ill with others, nor do to others what he would not that others should do to him.
This being granted, we may say, that the Laws have been established in favour, and for the sake of wise Men, not to hinder them from committing Injustice, but to prevent others from doing them wrong; for of their own accord they are so inclined, that if there were no Laws they would injure no body; for they have limited their Desires, and confined them to the necessities of Nature; to supply which there is no need of doing In∣justice, for there is no Pleasure Nature allows of which will cause us to wrong any body; for those exor∣bitances and irregular Desires which proceed from our vain and unruly Passions and Lusts, are the only Causes of Mischief.
