There is, undoubtedly, a fundamental difference between understanding and learning the reasoning of others, and being able "to reason," between learning how an artist may see the external world according to his prevailing interest in color, harmony, and form, and actually seeing the external world about a fulcrum which sustains one's own aesthetical creation. In the mind of one who "learns the things of others" we may find, as in a sack of old clothes hanging over the shoulders of a hawker, solutions of the problems of Euclid, together with the images of Raphael's works, ideas of history and geography, and rules of style, huddled together with a like indifference and a like sensation of "weight." While, on the other hand, he who uses all these things for his own life, is like the person who is assisted in attaining his own welfare, his own relief, his own comfort by those same objects which are merely burdens when in the sack of the hawker. Such objects are, however, no longer huddled together without order and without purpose in a closed bag, but set out in the spacious rooms of a well-ordered house. The mind which constructs may contain a great deal more than that mind in which pieces of knowledge are heaped up as in the bag; and in that mind, as in the house, the objects are clearly divided one from another, harmoniously arranged, and distinctive in their uses. Between "understanding" because another person seeks to impress upon us the explanation of a thing by speech, and "understanding" the thing of ourselves, there is an immeasurable distance; the two are comparable to the impression made in soft wax, which will subsequently be effaced and replaced by other impressions, and the form chiselled in the marble by an artist, as his creation. He who understands of himself has an unforeseen impression; he feels that his consciousness has been liberated, and something luminous shines forth within him. Understanding, then, is not a matter of indifference; it is the beginning of _something_; sometimes it is the beginning of a life which renews itself within us. Perhaps no emotion is more fruitful for man than the intellectual emotion. He who makes a discovery rich in results certainly enjoys the greatest of human felicities; but even he who merely "understands" gets a lofty enjoyment which will rise superior to and overcome the most acute suffering. Indeed, he who is oppressed by a misfortune, if he can be brought to differentiate his own case from that of another, or to see a reason for his affliction, experiences relief, and a "sense of salvation." Amidst the confused darkness in which he was plunged, a consoling ray of intellectual light has reached him. The difficult matter, indeed, is to find the way of escape in the hour of darkness. When we reflect that a dog may die of grief on the grave of his master, and that a mother can survive on the grave of her only son, we see at once that it is the light of
