One should not wrongly MATERIALISE "cause" and "effect," as the natural philosophers do (and whoever like them naturalize in thinking at present), according to the prevailing mechanical doltishness which makes the cause press and push until it "effects" its end; one should use "cause" and "effect" only as pure CONCEPTIONS, that is to say, as conventional fictions for the purpose of designation and mutual understanding,—NOT for explanation. In "being-in-itself" there is nothing of "casual-connection," of "necessity," or of "psychological non-freedom"; there the effect does NOT follow the cause, there "law" does not obtain. It is WE alone who have devised cause, sequence, reciprocity, relativity, constraint, number, law, freedom, motive, and purpose; and when we interpret and intermix this symbol-world, as "being-in-itself," with things, we act once more as we have always acted—MYTHOLOGICALLY.
