It must, in the first place, be allowed that, the more violent the passions are, the more are laws necessary to keep them under restraint. But, setting aside the inadequacy of laws to effect this purpose, which is evident from the crimes and disorders to which these passions daily give rise among us, we should do well to inquire if these evils did not spring up with the laws themselves; for in this case, even if the laws were capable of repressing such evils, it is the least that could be expected from them, that they should check a mischief which would not have arisen without them.
Let us begin by distinguishing between the physical and moral ingredients in the feeling of love. The physical part of love is that general desire which urges the sexes to union with each other. The moral part is that which determines and fixes this desire exclusively upon one particular object; or at least gives it a greater degree of energy toward the object thus preferred. It is easy to see that the moral part of love is a factitious feeling, born of social usage, and enhanced by the women with much care and cleverness, to establish their empire, and put in power the sex which ought to obey. This feeling, being founded on certain ideas of beauty and merit which a savage is not in a position to acquire, and on comparisons which he is incapable of making, must be for him almost non-existent; for, as his mind cannot form abstract ideas of proportion and regularity, so his heart is not susceptible of the feelings of love and admiration, which are even insensibly produced by the application of these ideas. He follows solely the character nature has implanted in him, and not tastes which he could never have acquired; so that every woman equally answers his purpose.
Men in a state of nature being confined merely to what is physical in love, and fortunate enough to be ignorant of those excellences, which whet the appetite while they increase the difficulty of gratifying it, must be subject to fewer and less violent fits of passion, and consequently fall into fewer and less violent disputes. The imagination, which causes such ravages among us, never speaks to the heart of savages, who quietly await the impulses of nature, yield to them involuntarily, with more pleasure than ardour, and, their wants once satisfied, lose the desire. It is therefore incontestable that love, as well as all other passions, must have acquired in society that glowing impetuosity, which makes
