Nature has appointed that the propagation of the species shall be the business of men who are young, strong and handsome; so that the race may not degenerate. This is the firm will and purpose of Nature in regard to the species, and it finds its expression in the passions of women. There is no law that is older or more powerful than this. Woe, then, to the man who sets up claims and interests that will conflict with it; whatever he may say and do, they will be unmercifully crushed at the first serious encounter. For the innate rule that governs women’s conduct, though it is secret and unformulated, nay, unconscious in its working, is this: We are justified in deceiving those who think they have acquired rights over the species by paying little attention to the individual, that is, to us. The constitution and, therefore, the welfare of the species have been placed in our hands and committed to our care, through the control we obtain over the next generation, which proceeds from us; let us discharge our duties conscientiously. But women have no abstract knowledge of this leading principle; they are conscious of it only as a concrete fact; and they have no other method of giving expression to it than the way in which they act when the opportunity arrives. And then their conscience does not trouble them so much as we fancy; for in the darkest recesses of their heart, they are aware that in committing a breach of their duty towards the individual, they have all the better fulfilled their duty towards the species, which is infinitely greater.[1]
