"We have our Arts so we won't die of Truth." - Ray Bradbury
The corollary is that the Arts are a lie.

"Another unsettling element in modern art is that common symptom of immaturity, the dread of doing what has been done before; for though one of the instincts of youth is imitation, another, equally imperious, is that of fiercely guarding against it. In this respect, the novelist of the present day is in danger of being caught in a vicious circle, for the insatiable demand for quick production tends to keep him in a state of perpetual immaturity, and the ready acceptance of his wares encourages him to think that no time need be wasted in studying the past history of his art, or in speculating on its principles. This conviction strengthens the belief that the so-called quality of "originality" may be impaired by too long brooding on one's theme and too close a commerce with the past; but the whole history of that past — in every domain of art - disproves this by what survives, and shows that every subject, to yield and to retain its full flavour, should be long carried in the mind, brooded upon, and fed with all the impressions and emotions which nourish its creator.
True originality consists not in a new manner but in a new vision. That new, that personal, vision is attained only by looking long enough at the object represented to make it the writer’s own; and the mind which would bring this secret germ to fruition must be able to nourish it with an accumulated wealth of knowledge and experience. To know any one thing one must not only know something of a great many others, but also, as Matthew Arnold long since pointed out, a great deal more of one's immediate subject than any partial presentation of it visibly includes; and Mr. Kipling's "What should they know of England who only England know?" might be taken as the symbolic watchword of the creative artist.
One is sometimes tempted to think that the generation which has invented the “fiction course” is getting the fiction it deserves. At any rate it is fostering in its young writers the conviction that art is neither long nor arduous, and perhaps blinding them to the fact that notoriety and mediocrity are often interchangeable terms. But though the trade-wind in fiction undoubtedly drives many beginners along the line of least resistance, and holds them there, it is far from being the sole cause of the present quest for short-cuts in art. There are writers indifferent to popular success, and even contemptuous of it, who sincerely believe that this line marks the path of the true vocation. Many people assume that the artist receives, at the outset of his career, the mysterious sealed orders known as “Inspiration,” and has only to let that sovereign impulse carry him where it will. Inspiration does indeed come at the outset to every creator, but it comes most often as an infant, helpless, stumbling, inarticulate, to be taught and guided; and the beginner, during this time of training his gift, is as likely to misuse it as a young person to make mistakes in teaching his first child."
