There is a good and a bad side to the two types of interest. The objective minded conquer the world in dealing with what they call reality. They bridge the water and dig up the earth; they invent, they plow, they sell and buy, they produce and distribute wealth, and they deal with the education that teaches how to do all these things. They find in the outer world an unalterable sense of reality, and they tend rather naively to accept themselves, their interests and efforts as normal. In their highest forms they are the scientist, reducing to law this tangle of outer realities, or the artist, who though he is a hybrid with deep subjective and objective interest, nevertheless remodels the outer world to his concept of beauty. These objective-minded folk, the bulk of the brawn and in lesser degree of the brain of the world, are apt to be "materialists," to value mainly quantity and to be self-complacent. Of course, since no man is purely objective, there come to them as to all moments of brooding over the eggs of their inner life, when they wonder whether they have reached out for the right things and whether the goods they seek or have are worth while. Such introspective interest comes on them when they are alone and the outer world does not reach in, or when they have witnessed death and misfortune, or when sickness and fatigue have reduced them to a feeling of weakness. For it is true that the objective minded are more often robust, hearty, with more natural lust, passion and desire than your introspectionists, more virile and less sensitive to fine impressions. The introspectionists, culling, chewing the cud of their experiences and sensations, find in their own reactions the realities. In fact, interested in consciousness, they are sometimes bold enough to deny the realities of anything else. Where the others build bridges, they build up the ideas of eternal good and bad, of beauty, of the transitory and the permanent, of now and eternity. They deal with abstract ideas, and they luxuriate in emotions. They build up beliefs where thought is the only reality and is omnipotent. They are the founders of religious, cults, fads and fancies. They inculcate the permanent ideals, because they are the only ones who interest themselves in something beside the show of the universe.
