Creation gave us instincts for a purpose. Without them we wouldn’t be complete human beings. If men and women didn’t exert themselves to be secure in their persons, made no effort to harvest food or construct shelter, there would be no survival. If they didn’t reproduce, the earth wouldn’t be populated. If there were no social instinct, if men cared nothing for the society of one another, there would be no society. So these desires—for the sex relation, for material and emotional security, and for companionship—are perfectly necessary and right, and surely God-given.
Yet these instincts, so necessary for our existence, often far exceed their proper functions. Powerfully, blindly, many times subtly, they drive us, dominate and insist upon ruling our lives. Our desires for sex, for material and emotional security, and for an important place in society often tyrannize us. When thus out of joint, man’s natural desires cause him great trouble, practically all the trouble there is. No human being, however good, is exempt from these troubles. Nearly every serious emotional problem can be seen as a case of misdirected instinct. When that happens, our great natural assets, the instincts, have turned into physical and mental liabilities.
