It will be noticed that Montesquieu by no means denies that there are general principles of justice. On the contrary, he positively asserts it.[Footnote: Ibid., iii. 91 (liv. i. c. 1).] But the great value of his teaching consists in the other lesson. "It is better to say that the government most in conformity with nature is that whose particular disposition is most in relation to the disposition of the people for which it is established." This principle may certainly be deduced from Aristotle; but it was none the less necessary to teach it in the eighteenth century; it is none the less necessary to teach it to-day. [Footnote: Ibid., iii. 99; Aristotle, _Politics_, liv. vii. c. ii.] The conception was a great one, so simple that it seems impossible that it could ever have been missed; but it was combated with violence on its announcement, and many brilliant and learned men have failed to grasp it.[Footnote: Montesq., iv. 145 _n_] Such are the persons in our own time who praise despotism in France, or who would set up parliamentary government in India. Montesquieu probably carried his theories too far. To the north he assigned energy and valor, as if the most widely conquering nations that Europe had then known had been the Norwegian and the Finn, instead of the Macedonian, the Italian, and the Spaniard. Sterility of soil he considered favorable to republics, fertility to monarchies. It was natural that a man in revolt against the long spiritual tyranny that had oppressed thought in Europe should have attributed excessive importance to material causes. Not the less did the idea contain its share of truth. Nor was his statement of this, which we may call his favorite theory, always excessive. "Several things," he says, "govern man; climate, religion, laws, the maxims of government, the examples of things past, morals, manners; whence comes a general spirit which is their result. Sometimes one of these forces dominates and sometimes another."[Footnote: Montesq., iv. 307 (liv. xix. c. 4).] It may be noted of Montesquieu, and as often of Voltaire, that each of them is constantly led astray by imperfect knowledge of foreign, and especially of barbarous and savage nations. Since the voyages and conquests of the Renaissance, accounts of strange countries had abounded in Europe, written in many cases by men anything but accurate, if not, in the words of Macaulay, "liars by a double right, as travellers and as Jesuits."[Footnote: _Essay on Machiavelli_.] The writers of a hundred and fifty years ago could use no better material than was to be had. They wished to draw instruction from distant objects, and their spy-glasses distorted shapes and modified colors. Imperfect knowledge of foreign countries sometimes led Montesquieu into curious mistakes; yet these affected his illustrations oftener than his theories.
