@Reconstructo,
I see what you are saying, and in essence I agree. But to say that "truth is a white lie" is just such an attempt to discover truth. What is the truth about truth? It's a passion for truth that leads one to question the will-to-truth, and also what it is that "truth" is made of.
Nietzsche had his faults, which I have criticized without restrain in the Nietzsche forum, but as a philosopher he is certainly a success. His name is not likely to be forgotten. He quite obvious had moments of intense happiness. See his description of inspiration in Ecce Homo. He danced around naked in his hotel rooms. True, he was also anguished, but this hardly negates his best ideas.
Nietzsche could be described as an extension of Kant, criticizing what Kant was afraid to. It's pretty obvious to us in the real world that desire distorts our perception. It's so strange to conceive of truth as a white lie.
Rorty was clearly influenced by Nietzsche's view of the truth as "an army of mobile metaphors, and Rorty seemed to have lived a comfortable life, with more than the average share of success and prestige. Hegel also had a dynamic theory of truth. He did pretty well himself. William James also deserves mention here.
