2953. It is by means of the female parts that the whole sexual system becomes for the first time equal to the perfected animal; through them for the first time the male tongue obtains an oral cavity.
2954. In the total representation of the sexual animal the female parts environ and include the male. This moment is called copulation.
2955. Copulation is the representation of the entire animal out of two incomplete ones. The sexual animal is only an entire beast in copulation, and is only then to be considered as equal to the encephalic animal. Copulation is a representation of the hermaphrodite.
2956. This propensity for bringing about the sexual animal's completion is sexual passion or lust.
2957. In copulation the male parts are "par excellence" the sensorial organ, the female only the recipient mouth. Both are properly organs of sense, but the one is operative or active, the other patient or passive.
2958. Previous to copulation the female parts are consequently inactive, just as digestion is before taste. As digestion first commences after taste has given up the food and excited the stomach to activity, so also the sexual function first commences in female animals, after the act of tasting is past.
2959. Through copulation what is female becomes masculine. It now secretes for the first time self-substantial semen. Through impregnation the female ovaria are first excited to secrete the saliva, which the whole animal contains in a state of solution.
2960. As the chyle becomes what it is, or is derived from the saliva and food; so from the semen and vitellus proceeds the fœtus, but in such a manner that the female substance gives it the mass, while upon this the male only bestows the polarity.
2961. Thus, were the male semen to actually solidify into the fœtus; it is still not its mass which comes into consideration in the latter, but only its polarizing strength. It supplies the place of the nervous system. This power appears to reside principally in the (seminal) Infusoria or animalcules, just as that of the blood does in the blood-globules. Meanwhile both are only signs of the maturity of their respective juices, as the Infusoria in sea-water are a proof also that the sea can produce other animals from its mucus or slime. The Infusoria are the primary mass of the Organic. Its life is only a manifestation of the seminal polarity. The Infusoria are semen which has been poured out over the earth. Propagation is only possible through reduction taking place to the infusorial primary mass.
2962. The semen and the ovum first meet or come together in the uterus.
