ETHICS produce unification. The lust for power is essentially separative; therefore it is not by indulging this lust that men can achieve the good results at which they profess to aim. The political techniques by means of which ambition can be restrained have been discussed in the chapter on Inequality; the educational and religious techniques, in the two succeeding chapters. We cannot expect that any of these techniques will be very successful, so long as ambition continues to be popularly regarded, as it is at present, as a virtue that should be implanted in the growing child and carefully fostered by precept and example. We have now to consider good and evil as manifested upon the intellectual plane. Intelligence, as we have seen, is one of the major virtues. Without intelligence, charity and the minor virtues can achieve very little. Intelligence may be classified as belonging to two kinds, according to the nature of its objects. There is the intelli- gence which consists in awareness of, and ability to deal with, things and events in the external world; and there is the intelligence which consists in awareness of, and ability to deal with, the phenomena of the inner world. In other words, there is intelligence in relation to the not-self and there is intelligence in relation to the self. The com- pletely intelligent person is intelligent both in regard to himself and to the outer world. But completely intelligent people are unhappily rare. Many men and women are capable of dealing very effectively with the external world in its practical, common-sense aspects, and are at the same time incapable of understanding or dealing with abstract ideas, logical relations or their own emotional and moral problems. Others again may possess a specialized com- petence in science, art or philosophy and yet be barbarously ignorant of their own nature and motives and quite in- competent to control their impulses. In popular language, *a philosopher5 is a man who behaves with restraint and L 321
