1. The Nature of Realization or Appreciation. Much of our experience is indirect; it is dependent upon signs which intervene between the things and ourselves, signs which stand for or represent the former. It is one thing to have been engaged in war, to have shared its dangers and hardships; it is another thing to hear or read about it. All language, all symbols, are implements of an indirect experience; in technical language the experience which is procured by their means is "mediated." It stands in contrast with an immediate, direct experience, something in which we take part vitally and at first hand, instead of through the intervention of representative media. As we have seen, the scope of personal, vitally direct experience is very limited. If it were not for the intervention of agencies for representing absent and distant affairs, our experience would remain almost on the level of that of the brutes. Every step from savagery to civilization is dependent upon the invention of media which enlarge the range of purely immediate experience and give it deepened as well as wider meaning by connecting it with things which can only be signified or symbolized. It is doubtless this fact which is the cause of the disposition to identify an uncultivated person with an illiterate person--so dependent are we on letters for effective representative or indirect experience. At the same time (as we have also had repeated occasion to see) there is always a danger that symbols will not be truly representative; danger that instead of really calling up the absent and remote in a way to make it enter a present experience, the linguistic media of representation will become an end in themselves. Formal education is peculiarly exposed to this danger, with the result that when literacy supervenes, mere bookishness, what is popularly termed the academic, too often comes with it. In colloquial speech, the phrase a "realizing sense" is used to express the urgency, warmth, and intimacy of a direct experience in contrast with the remote, pallid, and coldly detached quality of a representative experience. The terms "mental realization" and "appreciation" (or genuine appreciation) are more elaborate names for the realizing sense of a thing. It is not possible to define these ideas except by synonyms, like "coming home to one" "really taking it in," etc., for the only way to appreciate what is meant by a direct experience of a thing is by having it. But it is the difference between reading a technical description of a picture, and seeing it; or between just seeing it and being moved by it; between learning mathematical equations about light and being carried away by some peculiarly glorious illumination of a misty landscape. We are thus met by the danger of the tendency of technique and other purely representative forms to encroach upon the sphere of direct appreciations; in other words, the tendency to
