Lastly, it is a biological principle that organs are developed by exercise and atrophied by continued repose; now, man and woman do not exercise their encephalic organs in the same manner; educational training, manners, prejudice, enforced habits tend to develop in the masculine what becomes atrophied in the feminine head; whence it follows that the differences empirically established are by no means the result of Nature, but of the accidental causes by which they have been produced. Conclusion: the two sexes therefore, when reared alike become developed alike, and are fit for the same functions, except those which concern the reproduction of the species. Here, gentlemen, is a theory complete in all its parts, tenable in an anatomo-biologic point of view, and which I challenge you to prove false, for I shall find replies to all your objections. II. We admit the principle that the sexes form series in physical, moral, intellectual, consequently functional respects. We believe that they should become subordinate to each other in proportion to their relative excellence; and we take the destiny of the species as the touchstone of their respective value. If we compare the sexes with each other, we prove in a general way, that man is merely woman on a coarser scale; we prove in the second place that he is far more animal than woman, since his muscular system is more fully developed and since he respires lower; so that he is most evidently a medium between woman and the higher species of apes. Woman alone contains and develops the human germ; she is the creator and preserver of the race. It is not quite certain that the co-operation of man is necessary for the work of reproduction; _this is the means chosen by Nature_, but human science will succeed, we hope, in delivering woman from this insupportable subjection. Analogy authorises us to believe that woman, the sole depositary of the human germ, is equally the sole depositary of all the moral and intellectual germs, whence it follows that she is the inspirer of all knowledge, all discoveries, all justice, the mother of all virtue. Our analogous deductions are confirmed by facts; woman employs her intellect in the concrete; she is an acute observer; man is only fit to construct paradoxes and to lose himself in the abyss of metaphysics; science has only emerged from the limbo of _à priora_ without confirmation, since the advent into this domain of the form of the feminine mind; we shall affirm, therefore, that true scholars are feminized minds.
