"Eroticism, an immediate aspect of inner experience as contrasted
with animal sexuality
Eroticism is one aspect of the inner life of man. We fail to realise this because man is everlastingly in search of an object outside himself but this object answers the innerness of the desire. The choice of object always depends on the personal taste of the subject; even if it lights upon a woman whom most men would choose, the decisive factor is often an intangible aspect of this woman, not an objective quality; possibly nothing about her would force our choice if she did not somehow touch our inner being. Even if our choice agrees with that of most other people, in fact, human choice is still different from that of animals. It appeals to the infinitely complex inner mobility which belongs to man alone. The animal itself does have a subjective life but this life seems to be conferred upon it like an inert object, once and for all. Human eroticism differs from animal sexuality precisely in this, that it calls inner life into play. In human consciousness eroticism is that within man which calls his being in question. Animal sexuality does make for disequilibrium and this disequilibrium is a threat to life, but the animal does not know that. Nothing resembling a question takes shape within it.
However that may be, eroticism is the sexual activity of man to the extent that it differs from the sexual activity of animals. Human sexual activity is not necessarily erotic but erotic it is whenever it is not rudimentary and purely animal.
The decisive importance of the transition from animal to man
We know little about the transition from animals to men but its importance is fundamental. The events taking place during this transition are probably hidden from us for ever yet we are better equipped to consider it than it might seem at first sight. We know that men made tools and used them in order to survive, and then, quite quickly no doubt, for less necessary purposes. In a word they distinguished themselves from the animals by work. At the same time they imposed restrictions known as taboos. Quite certainly these taboos were primarily concerned with the dead. Probably at the same time, or nearly so, they were connected with sexual activity. We know the early date of the attitudes towards death through the numerous discoveries of bones gathered together by contemporary men. In any case, Neanderthal man, who was not quite a true man, who had not yet adopted exclusively an upright posture and whose skull was not so different as ours from that of the anthropoids, did often bury his dead. Sexual taboos certainly do not date from these remote times. We may say that they appeared as humanity appeared, but nothing tangible supports this view in so far as we ought to draw conclusions from prehistoric data. Burying the dead leaves traces, but nothing remains to give us the slightest hint about the sexual restrictions of earliest man.
We can only admit that they worked, since we have their tools. Since work, as far as we can tell, logically gave rise to the reaction which determined the attitude towards death, it is legitimate to believe that the taboo regulating and limiting sexuality was also due to it, and the generality of behaviour that is essentially human - work, awareness of death, sexual continence - goes back to the same remote past."
