Book II

121. CAUSE AND EFFECT.— On this mirror— and our intellect is a mirror—something is going on that indicates regularity: a certain thing is each time followed by another certain thing. When we perceive this and wish to give it a name, we call it cause and effect,—fools that we are! as if in this we had understood or could understand anything! For, of course, we have seen nothing but the images of causes and effects, and it is just this figurativeness which renders it impossible for us to see a more substantial relation than that of sequence!

Friedrich Nietzsche
