And seeing every man is presumed to do all things in order to his own benefit, no man is a fit arbitrator in his own cause; and if he were never so fit; yet equity allowing to each party equal benefit, if one be admitted to be judge, the other is to be admitted also; and so the controversy, that is, the cause of war, remains against the law of Nature.

For the same reason no man in any cause ought to be received for arbitrator, to whom greater profit, or honour, or pleasure apparently ariseth out of the victory of one party than of the other: for he hath taken, though an unavoidable bribe, yet a bribe; and no man can be obliged to trust him. And thus also the controversy, and the condition of war remaineth, contrary to the law of Nature.

And in a controversy of “fact,” the judge being to give no more credit to one than to the other, if there be no other arguments, must give credit to a third; or to a third and fourth; or more: for else the question is undecided, and left to force, contrary to the law of Nature.
