Love, he says, is physical and moral. The physical side is that general desire which leads to the union of the sexes. The moral side is that which fixes that desire on one exclusive object, or at least that which gives the exclusive desire a greater energy. Now it is easy to see that this moral side of love is a factitious feeling, born of the usage of society, and vaunted by women with much skill and care in order to establish their empire, and to give dominion to the sex which ought to obey. This feeling is dull in the savage, who has no abstract ideas of regularity or beauty; he is not troubled with imagination, which causes so many woes to civilized man. "Let us conclude that the savage man, wandering in forests, without manufactures, without language, without a home, without war, and without connections, with no need of his kind, and no desire to injure it, perhaps never recognizing one person individually, subject to few passions, and sufficient to himself, had only the feeling and the intelligence proper to his state; that he felt only his real needs; he looked only at those things which he thought it was for his interest to see, and his intelligence made no more progress than his vanity. If, by chance, he made some discovery, he could not communicate it, not recognizing even his own children. The art perished with the inventor. There was neither education nor progress; the generations multiplied uselessly; and, as all started from the same point, the centuries went by with all the rudeness of the first age; the species was already old, and man still remained a child."
