III. For it might be at first thought that the whole kingdom of imagination was one of deception also. Not so: the action of the imagination is a voluntary summoning of the conceptions of things absent or impossible; and the pleasure and nobility of the imagination partly consist in its knowledge and contemplation of them as such, i.e. in the knowledge of their actual absence or impossibility at the moment of their apparent presence or reality. When the imagination deceives it becomes madness. It is a noble faculty so long as it confesses its own ideality; when it ceases to confess this, it is insanity. All the difference lies in the fact of the confession, in there being _no_ deception. It is necessary to our rank as spiritual creatures, that we should be able to invent and to behold what is not; and to our rank as moral creatures that we should know and confess at the same time that it is not. IV. Again, it might be thought, and has been thought, that the whole art of painting is nothing else than an endeavor to deceive. Not so: it is, on the contrary, a statement of certain facts, in the clearest possible way. For instance: I desire to give an account of a mountain or of a rock; I begin by telling its shape. But words will not do this distinctly, and I draw its shape, and say, "This was its shape." Next: I would fain represent its color; but words will not do this either, and I dye the paper, and say, "This was its color." Such a process may be carried on until the scene appears to exist, and a high pleasure may be taken in its apparent existence. This is a communicated act of imagination, but no lie. The lie can consist only in an _assertion_ of its existence (which is never for one instant made, implied, or believed), or else in false statements of forms and colors (which are, indeed, made and believed to our great loss, continually). And observe, also, that so degrading a thing is deception in even the approach and appearance of it, that all painting which even reaches the mark of apparent realization, is degraded in so doing. I have enough insisted on this point in another place.
