Only by forgetting that primitive world of metaphors, only by the congelation and coagulation of an original mass of similes and percepts pouring forth as a fiery liquid out of the primal faculty of human fancy, only by the invincible faith, that _this_ sun, _this_ window, _this_ table is a truth in itself: in short only by the fact that man forgets himself as subject, and what is more as an _artistically creating_ subject: only by all this does he live with some repose, safety and consequence. If he were able to get out of the prison walls of this faith, even for an instant only, his "self-consciousness would be destroyed at once. Already it costs him some trouble to admit to himself that the insect and the bird perceive a world different from his own, and that the question, which of the two world-perceptions is more accurate, is quite a senseless one, since to decide this question it would be necessary to apply the standard of _right perception,_ i.e., to apply a standard which _does not exist._ On the whole it seems to me that the "right perception"--which would mean the adequate expression of an object in the subject--is a nonentity full of contradictions: for between two utterly different spheres, as between subject and object, there is no causality, no accuracy, no expression, but at the utmost an _æsthetical_ relation, I mean a suggestive metamorphosis, a stammering translation into quite a distinct foreign language, for which purpose however there is needed at any rate an intermediate sphere, an intermediate force, freely composing and freely inventing. The word "phenomenon" contains many seductions, and on that account I avoid it as much as possible, for it is not true that the essence of things appears in the empiric world. A painter who had no hands and wanted to express the picture distinctly present to his mind by the agency of song, would still reveal much more with this permutation of spheres, than the empiric world reveals about the essence of things. The very relation of a nerve-stimulus to the produced percept is in itself no necessary one; but if the same percept has been reproduced millions of times and has been the inheritance of many successive generations of man, and in the end appears each time to all mankind as the result of the same cause, then it attains finally for man the same importance as if it were _the_ unique, necessary percept and as if that relation between the original nerve-stimulus and the percept produced were a close relation of causality: just as a dream eternally repeated, would be perceived and judged as though real. But the congelation and coagulation of a metaphor does not at all guarantee the necessity and exclusive justification of that metaphor.
