"The ancient Greeks, though born in a warm climate, seem to have been much addicted to the bottle; nor were their parties of pleasure any thing but matches of drinking among men, who passed their time altogether apart from the fair. Yet when Alexander led the Greeks into Persia, a still more southern climate, they multiplied their debauches of this kind, in imitation of the Persian manners.[290:1] So honourable was the character of a drunkard among the Persians, that Cyrus the younger, soliciting the sober Lacedemonians for succour against his brother Artaxerxes, claims it chiefly on account of his superior endowments, as more valorous, more bountiful, and a better drinker.[290:2] Darius Hystaspes made it be inscribed on his tomb-stone, among his other virtues and princely qualities, that no one could bear a greater quantity of liquor." The other two essays, though bearing on subjects which have now almost dropped out of political discussion, "The Original Contract," and "Passive Obedience," trod close on the heels of the long conflict in which Milton, Salmasius, Hobbes, Sidney, Locke, and Filmer, had been partakers; and while the din of arms was far from being exhausted, they professed to hold the balance equally between the combatants, or, more properly speaking, to examine philosophically the merits of the theory of each party, without taking up the angry arguments of either. They are, in truth, but a farther adaptation to politics of those utilitarian theories which Hume had previously applied both to private morals and to government. And the principle they promulgate is, that the citizen's allegiance to the laws and constitution of his country, has its proper foundation neither in an acknowledgment of the divine right of any governor, nor in a contract with him by which both parties are bound, but in the moral duty of respecting internal peace and order, and of avoiding outbreaks which may plunge the people into anarchy and misery, to gratify the pride or baser passions of turbulent individuals. It must have been on his return on this occasion, that Hume rejoined the family circle at Ninewells, bereaved of the parent whose devotion to his training and education he has so affectionately commemorated. "I went down," he says, "in 1749, and lived two years with my brother at his country house, for my mother was now dead."[291:1] In a letter, which will have to be afterwards referred to, by Dr. Black, to Adam Smith, written when Hume was on his death-bed, and in relation to his final illness, there is the remark, "His mother," he says, "had precisely the same constitution with himself, and died of this very disorder." On this subject, the American traveller, Silliman, gave currency to a foolish and improbable story, which he puts in the following shape:--
