VII. The Beginnings of Sex Duality

All that is stated here refers to the latest period before the separation of the sexes. The latter proceeded slowly and gradually. For a long time before its actual appearance, mankind began to develop in such a way that one individual was born with more of the masculine, the other with more of the feminine character. Nevertheless, the characteristics of the opposite sex were present in every individual, so that spontaneous generation was possible, though not at all times, for it was dependent upon the influences of external conditions at certain seasons of the year. In diverse matters mankind as a whole depended to a large extent on such external circumstances. For that reason he had to regulate all his undertakings in accordance with such outer conditions; in accordance, for example, with the course of sun and moon. This regulation did not, however, take place consciously, in the present sense of the term, but was carried out in a manner which must rather be called instinctive, a term indicating the mental life of the man of that time.
