The Seventeenth, No Man Is His Own Judge
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 equall benefit, if one be admitted to be Judge, the other is to be admitted also; & so the controversie, that is, the cause of War, remains, against the Law of Nature.
The Eighteenth, No Man To Be Judge, That Has In Him Cause Of Partiality
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 unavoydable bribe, yet) a bribe; and no man can be obliged to trust him. And thus also the controversie, and the condition of War remaineth, contrary to the Law of Nature.
The Nineteenth, Of Witnesse
And in a controversie 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.
These are the Lawes of Nature, dictating Peace, for a means of the conservation of men in multitudes; and which onely concern the doctrine of Civill Society. There be other things tending to the destruction of particular men; as Drunkenness, and all other parts of Intemperance; which may therefore also be reckoned amongst those things which the Law of Nature hath forbidden; but are not necessary to be mentioned, nor are pertinent enough to this place.
A Rule, By Which The Laws Of Nature May Easily Be Examined
And though this may seem too subtile a deduction of the Lawes of Nature, to be taken notice of by all men; whereof the most part are too busie in getting food, and the rest too negligent to understand; yet to leave all men unexcusable, they have been contracted into one easie sum, intelligible even to the meanest capacity; and that is, “Do not that to another, which thou wouldest not have done to thy selfe;” which sheweth him, that he has no more to do in learning the Lawes of Nature, but, when weighing the actions of other men with his own, they seem too heavy, to put them into the other part of the ballance, and his own into their place, that his own passions, and selfe-love, may adde nothing to the weight; and then there is none of these Lawes of Nature that will not appear unto him very reasonable.
