Ignorance of the causes, and original constitution of right, equity, law, and justice, disposeth a man to make custom and example the rule of his actions; in such manner, as to think that unjust which it hath been the custom to punish; and that just, of the impunity and approbation whereof they can produce an example, or, as the lawyers which only use this false measure of justice barbarously call it, a precedent; like little children, that have no other rule of good and evil manners, but the correction they receive from their parents and masters; save that children are constant to their rule, whereas, men are not so; because grown old, and stubborn, they appeal from custom to reason, and from reason to custom, as it serves their turn; receding from custom when their interest requires it, and setting themselves against reason, as oft as reason is against them: which is the cause, that the doctrine of right and wrong is perpetually disputed, both by the pen and the sword: whereas the doctrine of lines, and figures, is not so; because men care not, in that subject, what be truth, as a thing that crosses no man’s ambition, profit or lust.
