The conflict of forces and the struggle of opposing wills are of the essence of our universe and alone hold it together.

No act can be quite so intimate as the sexual embrace.

The prevalence of suicide, without doubt, is a test of height in civilization; it means that the population is winding up its nervous and intellectual system to the utmost point of tension and that sometimes it snaps.

Of woman as a real human being, with sexual needs and sexual responsibilities, morality has often known nothing.

The sexual regions constitute a particularly vulnerable spot, and remain so even in man, and the need for their protection which thus exists conflicts with the prominent display required for sexual allurement. This end is far more effectively attained, with greater advantage and less disadvantage, by concentrating the chief ensigns of sexual attractiveness on the upper and more conspicuous parts of the body. This method is well-nigh universal among animals as well as in man.

The family only represents one aspect, however important an aspect, of a human being's functions and activities. A life is beautiful and ideal or the reverse, only when we have taken into our consideration the social as well as the family relationship.

The romantic embrace can only be compared with music and with prayer.
