Cause and effect—On this mirror—for our intellect is a mirror—something is going on which shows regularity; a certain thing, each time, follows another certain thing. This, if we want to perceive it and give it a line, we call cause and effect. We fools! As if, in this, we understood or could understand anything! For we have seen nothing but the images of " cause and effect." And this very figurativeness makes the insight into a more substantial relation than that of sequence impossible.

A single instance of this kind suffices to open our eyes as to the fallacy of “purposes" in nature.
