The reason of the law is the life of the law; for though a man can tell the law, yet if he know not the reason thereof, he shall soone forget his superficial knowledge. But when he findeth the right reason of the law, and so bringeth it to his natural reason, that he comprehendeth it as his own, this will not only serve him for the understanding of that particular case, but of many others; for cognitio legis est copulata et complicata; and this knowledge will long remaine with him.
