Concerning the transaction, there is more than one point to be noted of importance to history. One is the light which it throws on Jefferson's personal qualities. Because this man held very firmly an abstract and reasoned theory of the State, could define and defend it with extraordinary lucidity and logic, and avowedly guided his public conduct by its light, there has been too much tendency to regard him as a mere theorist, a sort of Girondia, noble in speculation and rhetoric, but unequal to practical affairs and insufficiently alive to concrete realities. He is often contrasted unfavourably with Hamilton in this respect: and yet he had, as events proved, by far the acuter sense of the trend of American popular opinion and the practical requirements of a government that should command its respect; and he made fewer mistakes in mere political tactics than did his rival. But his diplomacy is the best answer to the charge. Let anyone who entertains it follow closely the despatches relating to the Louisiana purchase, and observe how shrewdly this supposed visionary can drive a good bargain for his country, even when matched against Talleyrand with Bonaparte behind him. One is reminded that before he entered politics he enjoyed among his fellow-planters a reputation for exceptional business acumen. Much more plausible is the accusation that Jefferson in the matter of Louisiana forgot his principles, and acted in a manner grossly inconsistent with his attitude when the Federalists were in power. Certainly, the purchase can only be defended constitutionally by giving a much larger construction to the powers of the Federal authority than even Hamilton had ever promulgated. If the silence of the Constitution on the subject must, as Jefferson had maintained, be taken as forbidding Congress and the Executive to charter a bank, how much more must a similar silence forbid them to expend millions in acquiring vast new territories beyond the borders of the Confederacy. In point of fact, Jefferson himself believed the step he and Congress were taking to be beyond their present powers, and would have preferred to have asked for a Constitutional Amendment to authorize it. But he readily gave way on this to those who represented that such a course would give the malcontent minority their chance, and perhaps jeopardize the whole scheme. The fact is, that "State Rights" were not to Jefferson a first principle, but a weapon which he used for the single purpose of resisting oligarchy. His first principle, in which he never wavered for a moment, was that laid down in the "Declaration"--the sovereignty of the General Will. To him Federalism was nothing and State Sovereignty was nothing but the keeping of the commandments of the people. Judged by this test, both his opposition to Hamilton's bank and his purchase of the Louisiana territory were justified; for on both occasions the nation was with him.
