This article intends to reconstitute the critical interpretation argumet of Habermas about the nietzschiane philosophy, focung a postface written in 1968, to a collection of texts by Nietzsche about knowledge theory. Our intention is to present the gênesis of interpretation, forteen years later, in the DFM (1982), where Nietzsche is appointed, by Habermas, as turnig point (Drehscheibe) of modernity, that bred, on this way "an irracional speech metaphysically defaced", basis of the post-modernity. However, as the postface is contemporary to the work, CI (1968), in which there is a chapter dedicated to Nietzsche, that complements the postface to muck, we decided to use this material to help our interpretation.
