Thirdly, Because the Ability of Counselling proceedeth from Experience, and long study; and no man is presumed to have experience in all those things that to the Administration of a great Common-wealth are necessary to be known, No Man Is Presumed To Be A Good Counsellour, But In Such Businesse, As He Hath Not Onely Been Much Versed In, But Hath Also Much Meditated On, And Considered. For seeing the businesse of a Common-wealth is this, to preserve the people at home, and defend them against forraign Invasion, we shall find, it requires great knowledge of the disposition of Man-kind, of the Rights of Government, and of the nature of Equity, Law, Justice, and Honour, not to be attained without study; And of the Strength, Commodities, Places, both of their own Country, and their Neighbours; as also of the inclinations, and designes of all Nations that may any way annoy them. And this is not attained to, without much experience. Of which things, not onely the whole summe, but every one of the particulars requires the age, and observation of a man in years, and of more than ordinary study. The wit required for Counsel, as I have said before is Judgement. And the differences of men in that point come from different education, of some to one kind of study, or businesse, and of others to another. When for the doing of any thing, there be Infallible rules, (as in Engines, and Edifices, the rules of Geometry,) all the experience of the world cannot equall his Counsell, that has learnt, or found out the Rule. And when there is no such Rule, he that hath most experience in that particular kind of businesse, has therein the best Judgement, and is the best Counsellour.
Fourthly, to be able to give Counsell to a Common-wealth, in a businesse that hath reference to another Common-wealth, It Is Necessary To Be Acquainted With The Intelligences, And Letters That Come From Thence, And With All The Records Of Treaties, And Other Transactions Of State Between Them; which none can doe, but such as the Representative shall think fit. By which we may see, that they who are not called to Counsell, can have no good Counsell in such cases to obtrude.
