The modesty of women, which, in its most primitive form among animals, is based on sexual periodicity, is, with that periodicity, an essential condition of courtship.

I always seem to have a vague feeling that he is a Satan among musicians, a fallen angel in the darkness who is perpetually seeking to fight his way back to happiness.

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.

A sublime faith in human imbecility has seldom led those who cherish it astray.

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.

Still, whether we like it or not, the task of speeding up the decrease of the human population becomes increasingly urgent.
