And, as in arithmetic, unpracticed men must, and professors themselves may often, err, and cast up false; so also in any other subject of reasoning, the ablest, most attentive, and most practiced men may deceive themselves, and infer false conclusions; not but that reason itself is always right reason, as well as arithmetic is a certain and infallible art: but no one man’s reason, nor the reason of any one number of men, makes the certainty; no more than an account is therefore well cast up, because a great many men have unanimously approved it. And therefore, as when there is a controversy in an account, the parties must by their own accord set up, for right reason, the reason of some arbitrator, or judge, to whose sentence they will both stand, or their controversy must either come to blows, or be undecided, for want of a right reason constituted by Nature; so is it also in all debates of what kind soever. And when men that think themselves wiser than all others, clamour and demand right reason for judge, yet seek no more, but that things should be determined by no other men’s reason but their own, it is as intolerable in the society of men, as it is in play after trump is turned, to use for trump on every occasion, that suit whereof they have most in their hand.
