Love is something far more than desire for sexual intercourse; it is the principal means of escape from the loneliness which afflicts most men and women throughout the greater part of their lives. There is a deep-seated fear, in most people, of the cold world and the possible cruelty of the herd ; there is a longing for affection, which is often concealed by roughness, boorishness or a bullying manner in men, and by nagging and scolding in women.
