Deleuze wrote that, “one of the principal motifs of Nietzsche’s work is that Kant had not carried out a true critique because he was not able to pose the problem of critique in terms of values”.
“True critique”? Nietzsche starts by addressing the value of truth, so I do not know what he would have made of the adjective true critique. We would better ask: What is the value of critique? What spirit critiques? Who is the one who critiques?
Is it the spirit of a child running to the sea shore or digging a sand castle? Is it the spirit of a child discovering the flow of water and the resistance of sank banks? Is it the spirit of a child celebrating her castle: look mummy!
Or the spirit of the adult, who scans the text for mistakes?
Or the spirit of the one who says the unexamined life is not worth living, or has no value? Critique – the measure of all things, even life itself? No! Life is the measure of critique. A lifeless examination is not worth the examining.
