The science of politics is and probably always will be unknown. Grotius, our leader in this branch of learning, is only a child, and what is worse an untruthful child. When I hear Grotius praised to the skies and Hobbes overwhelmed with abuse, I perceive how little sensible men have read or understood these authors. As a matter of fact, their principles are exactly alike, they only differ in their mode of expression. Their methods are also different: Hobbes relies on sophism; Grotius relies on the poets; they are agreed in everything else. In modern times the only man who could have created this vast and useless science was the illustrious Montesquieu. But he was not concerned with the principles of political law; he was content to deal with the positive laws of settled governments; and nothing could be more different than these two branches of study. Yet he who would judge wisely in matters of actual government is forced to combine the two; he must know what ought to be in order to judge what is.
