At all periods in the history of civilized races, pathology has also led to extra-conjugal sexual intercourse. Here, homosexual love in general, and love of boys or pediastry, has always played the principal part. We shall speak of this in Chapter VIII. Among the Hebrews, Persians, Etruscans, and especially the Greeks, it was held in high esteem. The Greek philosophers regarded it as based on an ideal homosexual love, and not as a vile form of prostitution. Solon, Aristides, Sophocles, Phidias, and Socrates were strongly suspected of homosexual practices, and they regarded this form of love as superior to the normal love of woman. Lesbian love, and other sexual aberrations, such as sadism, have also played a historical role, as we shall see. CONCLUSIONS Primitive human marriage was probably of short duration; when man later on became carnivorous, and had to obtain food for his children by hunting, sexual unions assumed a more constant character. It is not the class or the tribe, but the family which constituted the primitive social condition of man, a condition in which marriage was a heritage from "pithecomorphous" ancestors, _i.e._, related to monkeys. Free sexual intercourse before marriage and frequent changes in the latter were then no doubt very common, but true promiscuity has never been the rule in primitive man. Patriarchism with its disastrous consequences has been the result of the preponderance of male power. In a higher degree of civilization this preponderance has produced marriage by purchase and polygamy. The barbarous form of the latter is now decreasing. A true higher culture leads gradually to durable love based on altruism and ethics, _i.e._, a relative and free monogamy. The development of marriage in civilization has gradually increased the rights of woman, and marriage contracts tend more and more in their modern forms to stipulate for complete equality of rights for both sexes. As Westermark says: "The history of human marriage is the history of a union in which women have gradually triumphed over the passions, prejudices and egoism of men." The term reëmancipation of women is historically more correct than the simple term emancipation, for before the institution of marriage, woman was free. Invented by the stronger male when he began to reason, marriage was at first only the servitude of woman. To give her complete liberty, it must be transformed afresh from top to bottom. APPENDIX
