It is to be presumed that a man of common-sense, who does not desire to please, desires nothing at all, since he must know that he cannot obtain anything without it. A skilful negotiator will most carefully distinguish between the little and the great objects of his business, and will be as frank and open in the former as he will be secret and pertinacious in the latter. He will, by his manners and address, endeavor, at least, to make his public adversaries his personal friends. He will flatter and engage the man, while he counterworks the minister; and he will never alienate people’s minds from him, by wrangling for points, either absolutely unattainable, or not worth attaining. He will make even a merit of giving up what he could not or would not carry, and sell a trifle for a thousand times its value. A foreign minister, who is concerned in great affairs, must necessarily have spies in his pay; but he must not too easily credit their informations, which are never exactly true, often very false. His best spies will always be those whom he does not pay, but whom he has engaged in his service by his dexterity and address, and who think themselves nothing less than spies. There is a certain jargon which in French I should call _un persiflage d’affaires_, that a foreign minister ought to be perfectly master of, and may use very advantageously at great entertainments in mixed companies, and in all occasions where he must speak and should say nothing. Well turned and well spoken, it seems to mean something, though in truth it means nothing. It is a kind of political _badinage_, which prevents or removes a thousand difficulties to which a foreign minister is exposed in mixed conversations. If ever the _volto sciolto_ and the _pensieri stretti_ are necessary, they are so in these affairs. A grave, dark, reserved, and mysterious air has _fœnum in cornu_. An even, easy, unembarrassed one invites confidence, and leaves no room for guesses and conjectures. Both stimulation and dissimulation are absolutely necessary for a foreign minister; and yet they must stop short of falsehood and perfidy: that middle point is the difficult one: there ability consists. He must often seem pleased, when he is vexed; and grave, when he is pleased; but he must never say either: that would be falsehood--an indelible stain to character. A foreign minister should be a most exact economist. An expense proportioned to his appointments and fortune is necessary; but, on the other hand, debt is inevitable ruin to him. It sinks him into disgrace at the court where he resides, and into the most servile and abject dependence on the court that sent him. As he cannot resent ill usage, he is sure to have enough of it. The Duc de Sully observes very justly, in his Memoirs, that nothing contributed more to his rise, than that prudent economy which he had observed from his youth, and by which he had always a sum of money beforehand, in case of emergencies.
