The strong man holds in a living blend strongly marked opposites. The idealists are not usually realistic, and the realists are not usually idealistic. The militant are not generally known to be passive, nor the passive to be militant. Seldom are the humble self-assertive, or the self-assertive humble. But life at it's best is a creative synthesis of opposites in fruitful harmony.
