We have to treat with contempt the woman who abjectly accepts the act, and her own passivity therein, as the whole duty of love.

We have to understand that the art of love has nothing to do with vice, and the acquirement of erotic personality nothing to do with sensuality.

But we have also to realise that the art of love is far from being the attainment of a refined and luxurious self-indulgence, and the acquirement of erotic personality of little worth unless it fortifies and enlarges the whole personality in all its aspects.

Now all this is difficult, and for some people even painful; to root up is a more serious matter than to sow; it cannot all be done in a day.
It is not easy to form a clear picture of the erotic life of the average man in our society.

To the best informed among us knowledge in this field only comes slowly.
