Nietzsche seems to have been unaware of the origin as well as of the modernity of the term “value” when he accepted it as a key notion in his assault on tradition. But when he began to devaluate the current values of society, the implications of the whole enterprise quickly became manifest. Ideas in the sense of absolute units had become identified with social values to such an extent that they simply ceased to exist once their value-character, their social status, was challenged. Nobody knew his way better than Nietzsche through the meandering paths of the modern spiritual labyrinth, where recollections and ideas of the past are hoarded up as though they had always been values which society depreciated whenever it needed better and newer commodities. Also, he was well aware of the profound nonsense of the new “value-free” science which was soon to degenerate into scientism and general scientific superstition and which never, despite all protests to the contrary, had anything in common with the Roman historians' attitude of sine ira et studio.
