For to know who knows the rules almost of any art, is a great degree of the knowledge of the same art; because no man can be assured of the truth of another’s rules, but he that is first taught to understand them. But the best signs of knowledge of any art, are, much conversing in it, and constant good effects of it. Good counsel comes not by lot, nor by inheritance; and therefore there is no more reason to expect good advice from the rich or noble, in matter of state, than in delineating the dimensions of a fortress; unless we shall think there needs no method in the study of the politics, as there does in the study of geometry, but only to be lookers-on; which is not so. For the politics is the harder study of the two.
