The natural world has its laws, and no man must interfere with them in the way of presentment any more than in the way of use; but they themselves may suggest laws of other kinds, and man may, if he pleases, invent a little world of his own, with its own laws; for there is that in him which delights in calling up new forms--which is the nearest, perhaps, he can come to creation. When such forms are new embodiments of old truths, we call them products of the Imagination; when they are mere inventions, however lovely, I should call them the work of the Fancy: in either case, Law has been diligently at work.
His world once invented, the highest law that comes next into play is, that there shall be harmony between the laws by which the new world has begun to exist; and in the process of his creation, the inventor must hold by those laws. The moment he forgets one of them, he makes the story, by its own postulates, incredible. To be able to live a moment in an imagined world, we must see the laws of its existence obeyed. Those broken, we fall out of it. The imagination in us, whose exercise is essential to the most temporary submission to the imagination of another, immediately, with the disappearance of Law, ceases to act. Suppose the gracious creatures of some childlike region of Fairyland talking either cockney or Gascon! Would not the tale, however lovelily begun, sink once to the level of the Burlesque--of all forms of literature the least worthy? A man's inventions may be stupid or clever, but if he does not hold by the laws of them, or if he makes one law jar with another, he contradicts himself as an inventor, he is no artist. He does not rightly consort his instruments, or he tunes them in different keys. The mind of man is the product of live Law; it thinks by law, it dwells in the midst of law, it gathers from law its growth; with law, therefore, can it alone work to any result. Inharmonious, unconsorting ideas will come to a man, but if he try to use one of such, his work will grow dull, and he will drop it from mere lack of interest. Law is the soil in which alone beauty will grow; beauty is the only stuff in which Truth can be clothed; and you may, if you will, call Imagination the tailor that cuts her garments to fit her, and Fancy his journeyman that puts the pieces of them together, or perhaps at most embroiders their button-holes. Obeying law, the maker works like his creator; not obeying law, he is such a fool as heaps a pile of stones and calls it a church.
Macdonald, The Fantastic Imagination.
