The besetting sin of the maxim-writer is to exaggerate one side of a matter by neglecting another; to secure point and emphasis of style, by limiting the range of thought; and hence it is that most maxims present but a portion of truth and cannot be received unqualified. They must often be brought back to the test of life itself, and confronted and compared with other sides of the experience they profess to embody. And when a maxim stands this trial and proves its worth, it is not every one to whom it is of value. To some it may be a positive evil. It makes the strongest appeal to those who never see more than one aspect of anything, hardening their hearts and blunting their minds; and even to those who could make a good use of it, there are times when it may mislead and be dangerous. Maxims in their application seem to need something of the physician's art: they must be handled with care, and applied with discretion. Like powerful drugs they may act with beneficent effect on a hardy constitution; they may brace it to effort, or calm the fever of a misguided activity; but great is the mischief they work where the mind is weak or disorganised. As a medicine may save a man at one time that would kill him at another, so the wise counsel of to-day may easily become the poisonous suggestion of to-morrow. With writers who depend for effect on mere qualities of style and ignore the weightier matters of depth and truth of observation, Goethe has nothing in common; nor with those who vainly imagine that insight is a kind of art, with a method that may be learned and applied. By constant practice a man of literary talent may, it is true, attain a fair mastery of language terse and attractive, and then set himself, if he will, to the deliberate creation of aphoristic wisdom or a philosophy of proverbs; mistaking the dexterous handling of a commonplace for the true process of discovery. The popular literature of the last generation supplies a terrible instance of the length to which the manufacture of maxims can thus be carried, for a time with immense success; and we have seen how a few years suffice to carry them and their author to obscurity. How different is the true process! The maxim that increases knowledge and enriches literature is of slow and rare appearance; it springs from a fine faculty of observation which is in no one's arbitrament, and only less rare than the gift of utterance which adds charm to a thought that itself strikes home with the power of impregnable truth. No amount or intensity of effort will alone produce it; but to the mind of genius it comes like a sudden revelation, flashing its light on a long course of patient attention. "What we call _Discovery_," says Goethe, "is the serious exercise and activity of an original feeling for truth. It is a synthesis of world and mind, giving the most blessed assurance of the eternal harmony of things."
