there they laugh: they do not understand me; I am not the mouth for these ears. - Friedrich Nietzsche

Only by forgetting this primitive world of metaphor can one live with any repose, security, and consistency: only by means of the petrification and coagulation of a mass of images which originally streamed from the primal faculty of human imagination like a fiery liquid, only in the invincible faith that this sun, this window, this table is a truth in itself, in short, only by forgetting that he himself is an artistically creating subject, does man live with any repose, security, and consistency. If but for an instant he could escape from the prison walls of this faith, his "self consciousness" would be immediately destroyed. It is even a difficult thing for him to admit to himself that the insect or the bird perceives an entirely different world from the one that man does, and that the question of which of these perceptions of the world is the more correct one is quite meaningless, for this would have to have been decided previously in accordance with the criterion of the correct perception, which means, in accordance with a criterion which is not available.

From experience. That something is irrational is no argument against its existence, but rather a condition for it.

"Every philosophy is a foreground philosophy — that is a hermit's judgment: "There is something arbitrary in his stopping here to look back and look around, in his not digging deeper here but laying his spade aside; there is also something suspicious about it." Every philosophy also conceals a philosophy; every opinion is also a hideout, every word also a mask."
