Sexual modesty is a fact of sexual passivity. The moment will come for the female to be in her turn active and strong, when she has been fecundated, and when she must give birth and food to the posterity of her race. The male then becomes inert; equable sharing of the expense of forces, just division of labour. This passivity of the female element is found again in the very figuration of animality, formed by the egg and the spermatozoide. One sees the play under the microscope: the egg waits, solid as a fortress or as a woman whom many men look on and covet; the little animals begin their attack, they besiege the enclosure, they butt it with their heads; one of them breaks the wall, he enters, and as soon as his tad-pole tail passes the breach, the wound recloses. The entire activity of this embryonic female reduces itself to this gesture; the greater part of her great sisters know no other. Their free-will nearly always consists in this: they receive one among the arrivals, without one's being able to know very well whether the choice is psychological or mechanical. The female waits, or flees, which is but another way of waiting, the active way; for not only _se cupit ante videnti_ but she desires to be taken, she wishes to fulfill her destiny. It is doubtless for this reason that, in species where the male is feeble or timid, the female resigns herself to an aggression demanded by care for future generations. In short, two forces are present, the magnet and the needle. Usually the female is the magnet, sometimes she is the needle. These are details of mechanism which do not modify the general march of the machine to its goal. At the origin of all feeling there is a fact irreducible and incomprehensible in itself. Common reasoning starts from the feeling to explain the fact; this gives the absurd result of making thought run in a set track, like a horse in a circus. Kantian ignorantism is the masterpiece of these training exercises, where, starting from the categoric stable the learned quadruped necessarily thither returns, having jumped through all the paper disks of scholastic reasoning. Observers of animal habits fall regularly into the prejudice of attributing, regularly, to beasts directive principles which only a long philosophic education and especially Christianity have rammed into restive human docility. Toussenel and Romanes are rarely superior to the possessors of a prodigious dog or miraculous cat: one must reject as apocryphal the anecdotes of animals' intelligence, and especially those boasting their sensibility, or celebrating their virtues; not that these are of necessity, inexact, but because the manner of interpreting them has vitiated, in principle, the manner of observation. One sole observer appears to me trustworthy in these matters, namely J. H. Fabre, the man who, since Réaumur, has penetrated furthest into the intimacy of insects, and whose work is veritably the creator, perhaps without his having suspected it, of a
