The statement already quoted, that “poetry is the most highly organized form of intellectual activity,” may be taken as a specimen of the abstract style in criticism. The confused distinction which exists in most heads between “abstract” and “concrete” is due not so much to a manifest fact of the existence of two types of mind, an abstract and a concrete, as to the existence of another type of mind, the verbal, or philosophic. I, of course, do not imply any general condemnation of philosophy; I am, for the moment, using the word “philosophic” to cover the unscientific ingredients of philosophy; to cover, in fact, the greater part of the philosophic output of the last hundred years. There are two ways in which a word may be “abstract.” It may have (the word “activity,” for example) a meaning which cannot be grasped by appeal to any of the senses; its apprehension may require a deliberate suppression of analogies of visual or muscular experience, which is none the less an effort of imagination. “Activity” will mean for the trained scientist, if he employ the term, either nothing at all or something still more exact than anything it suggests to us. If we are allowed to accept certain remarks of Pascal and Mr. Bertrand Russell about mathematics, we believe that the mathematician deals with objects—if he will permit us to call them objects—which directly affect his sensibility. And during a good part of history the philosopher endeavoured to deal with objects which he believed to be of the same exactness as the mathematician’s. Finally Hegel arrived, and if not perhaps the first, he was certainly the most prodigious exponent of emotional systematization, dealing with his emotions as if they were definite objects which had aroused those emotions. His followers have as a rule taken for granted that words have definite meanings, overlooking the tendency of words to become indefinite emotions. (No one who had not witnessed the event could imagine the conviction in the tone of Professor Eucken as he pounded the table and exclaimed _Was ist Geist? Geist ist ..._) If verbalism were confined to professional philosophers, no harm would be done. But their corruption has extended very far. Compare a mediæval theologian or mystic, compare a seventeenth-century preacher, with any “liberal” sermon since Schleiermacher, and you will observe that words have changed their meanings. What they have lost is definite, and what they have gained is indefinite.
