Reproduction is so primitive and fundamental a function of vital organisms that the mechanism by which it is assured is highly complex and not yet clearly understood. It is not necessarily connected with sex, nor is sex necessarily connected with reproduction.
Havelock EllisThe modesty of women, which, in its most primitive form among animals, is based on sexual periodicity, is, with that periodicity, an essential condition of courtship.
Havelock EllisThere can be no sexual love without lust; but, on the other hand, until the currents of lust in the organism have been irradiatedas to affect other parts of the psychic organism--at the least the affections and the social feelings--it is not yet sexual love. Lust, the specific sexual impulse, is indeed the primary and essential element in this synthesis, for it alone is adequate to the end of reproduction, not only in animals but in men. But it is not until lust is expanded and irradiated that it develops into the exquisite and enthralling flower of love.
Havelock EllisThe largely objective character of beauty is further indicated by the fact that to a considerable extent beauty is the expression of health. A well and harmoniously developed body, tense muscles, an elastic and finely toned skin, bright eyes, grace and animation of carriage- all these things which are essential to beauty are the conditions of health.
