Montesquieu[1] (1689-1755) made Locke's doctrine of constitutional monarchy and the division of powers (pp. 179-180), with which he joins the historical point of view of Bodin and the naturalistic positions of the time, the common property of the cultivated world. Laws must be adapted to the character and spirit of the nation; the spirit of the people, again, is the result of nature, of the past, of manners, of religion, and of political institutions. Nature has bestowed many gifts on the Southern peoples, but few on those of the North; hence the latter need freedom, while the former readily dispense with it. Warm climates produce greater sensibility and passionateness, cold ones, muscular vigor and industry; in the temperate zones nations are less constant in their habits, their vices, and their virtues. The laws of religion concern man as man, those of the state concern him as a citizen; the former have for their object the moral good of the individual, the latter, the welfare of society; the first aim at immutable, the second at mutable good. Laws and manners are closely interrelated. Right is older than the state, and the law of justice holds even in the state of nature; but in order to assure peace positive right is required in three forms, international, political, and civil. [Footnote 1: Montesquieu, _Persian Letters_, 1721; _Considerations on the Causes of the Greatness of the Romans and of their Decadence_, 1734; _Spirit of Laws_, 1748.] Each of the four political forms has a passion for its underlying principle: despotism has fear; monarchy, honor (personal and class prejudice); aristocracy, the moderation of the nobility; democracy, political virtue, which subordinates personal to general welfare, and especially the inclination to equality and frugality. While republics are destroyed by extravagance, lust, and self-seeking, a monarchy can dispense with civil virtue, patriotism, and moral disinterestedness, since in it false honor, luxury, and wantonness subserve the public good. Great states tend toward despotism; smaller ones toward aristocracy, or a democratic republicanism; for those of medium size monarchy, which is intermediate between the two former, is the best form of constitution. Although Montesquieu, in his _Lettres Persanes_, shows himself enthusiastic for the federal republics of Switzerland and the Netherlands, his opinions are different after his return from England, and in his _Esprit des Lois_ he praises the English form of government as the ideal of civil liberty.
