XVI. From all that has been said, it may be inferred, that written directions, are of little, or no service in these cases. They make politicians for a coffee-house, but not for the cabinet; and may teach people to talk, but not to act; for the hoping to find the circumstances of the business to be treated upon, the same with those of the case or cases in the book, would be entertaining a metaphysical and uncertain expectation: on account, both of the substantial and accidental diversity of the geniuses with whom you are to treat; and also, on account of the diversity in the mode of acting by the same agent, at different times. This last circumstance, which is but little attended to, is sufficient of itself, for the reasons we have mentioned before, to produce effects, totally different from those, we are taught to expect by the documents. SECT. IV. XVII. If the instruction of great masters was capable of making a man a politician, Richard Cromwel, the son of Oliver, should have been one of the greatest the world ever produced. The same Oliver, who after the tragical death of Charles the First of England, which he had a principal hand in accomplishing, erected himself into the tyrant of that kingdom, under the title of a Protector; and without doubt, Cromwel the father was one of the most able politicians which either that, or any other age had ever seen. His industry and his valour, raised him from a middling station of life, to the highest degree of military and magisterial rank. His address and resolution, enabled him to accomplish that unexampled attempt, of trying, and with all the formality of a legal process, condemning his own Sovereign to an ignominious death. When the King was dispatched, he abolished the house of Lords, and vested the whole authority of parliament in the Commons; whom he afterwards divested of all their power, by driving the members when they were assembled, ignominiously out of their house; and as a testimony of the arbitrary authority with which he acted, and to shew that was not a transitory expulsion, he caused a board to be nailed on the outside of the door, on which was the following inscription, _This house to be let_. In fine, he ruled that kingdom to his last gasp, with a more absolute sway, than any King who had ever gone before, or since his time has succeeded to the throne; bringing about, that a parliament being convened by himself for the purpose, should declare the title and office of Protector hereditary in his family. All this he executed in a nation, so fierce and zealous of their liberties as the English, which is the clearest proof that can be given, of his supreme political abilities. In reality, I am disposed to believe all circumstances considered, that there never to this day, has appeared a man, who did so much, or has shewed so many, and so great marks of political ability, as Oliver Cromwel.
