hungry, that they are seldom cold, and that they are rarely exposed to weariness, or to want of any kind. The most eloquent exhortation of this kind will have little effect upon him. If you would hope to succeed, you must describe to him the conveniency and arrangement of the different apartments in their palaces; you must explain to him the propriety of their equipages, and point out to him the number, the order, and the different offices of all their attendants. If any thing is capable of making impression upon him, this will. Yet all these things tend only to keep off the sun and the rain, and save them from hunger and cold, from want and weariness. In the same manner, if you would implant public virtue in the breast of him who seems heedless of the interest of his country, it will often be to no purpose to tell him, what superior advantages the subjects of a well-governed state enjoy; that they are better lodged, that they are better clothed, that they are better fed. These considerations will commonly make no great impression. You will be more likely to persuade, if you describe the great system of public police which procures these advantages, if you explain the connexions and dependencies of its several parts, their mutual subordination to one another, and their general subserviency to the happiness of the society; if you show how this system might be introduced into his own country, what it is that hinders it from taking place there at present, how those {165} obstructions might be removed, and all the several wheels of the machine of government be made to move with more harmony and smoothness, without grating upon one another, or mutually retarding one another's motions. It is scarce possible that a man should listen to a discourse of this kind, and not feel himself animated to some degree of public spirit. He will, at least for a moment, feel some desire to remove those obstructions, and to put into motion so beautiful and so orderly a machine. Nothing tends so much to promote public spirit as the study of politics, of the several systems of civil government, their advantages and disadvantages, of the constitution of our own country, its situation, and interest with regard to foreign nations, its commerce, its defence, the disadvantages it labours under, the dangers to which it may be exposed, how to remove the one, and how to guard against the other. Upon this account political disquisition, if just and reasonable and practicable, are of all the works of speculation the most useful. Even the weakest and the worst of them are not altogether without their utility. They serve at least to animate the public passions of men, and rouse them to seek out the means of promoting the happiness of the society. ----- CHAP.
