But defects as well as valuable qualities are transmitted from one sex to the other: if woman has profited by the brain-growth of man, he has in his turn been retarded in his development by the sluggishness in the development of woman's brain, produced by the reduction to the smallest minimum of intellectual activity to which he has condemned her. The breeders who seek the choicest results are as careful to have irreproachable females as males; amateur cockfighters attach as much importance to the selection of the pullets as to the cocks, they produce only from those which are armed with spurs and which have the fighting spirit. It may be said that humanity, since it emerged from communism of the clan to live under the system of private property, has been developed by the efforts of one sex alone and that its evolution has been retarded through the obstacles interposed by the other sex. Man by systematically depriving woman of the means of development, material and intellectual, has made of her a force retarding human progress. In fact if we study and compare the different periods of savagery and barbarism, we cannot but observe the continuous and remarkable progress in human mind, because women and men, exercising freely their physical and mental faculties, contribute equally to the evolution of the species; this has been retarded ever since humanity entered into the period of civilization and private property, because then woman, constrained and confined in her development, cannot contribute to it in so effective a way. The senile stagnation in which China has vegetated for more than a thousand years can only be attributed to the degradation of woman, which has gone to the point of the cruel mutilation of her feet that she may be imprisoned the more closely in the woman's quarters. Europe also suffers from the degradation of woman, since in spite of the extraordinary material progress of these last two thousand years and the increasing and no less extraordinary accumulation of human knowledge, it cannot be maintained that the brain of the civilized modern exceeds in power and capacity that of the Greeks of the classic epoch, which extends from the seventh to the fourth century before the Christian era. It is certain that a Victor Hugo, a Zola, or any university graduate or doctor has stored in his brain an abundance of positive and diversified conceptions not possessed by Aeschylus, Anaxagoras, Protagoras and Aristotle, but that does not prove that his imagination and his intelligence, or that of his contemporaries is more rich, more varied and more vast than that of the generations of Ionia and Attica, who were the artificers of that incomparable budding and blossoming of science, philosophy, literature and art at which history marvels and who reveled in that subtle and paradoxical play of sophistical philosophy, the like of which has not again been seen. The sophists—Photagoras, Gorgias, Socrates, Plato,
