I rather shared Nietzsche's conception of the kind of individual that an ideal education should be cultivating. 'Authenticity' is not Nietzsche's term, but as used by some existentialists, it nicely captures what Nietzsche admired - the resolve of an individual person to forge his or her own 'table of values', to be emancipated from strait-jacketing conventions, traditions, and ideologies. As embodied in the 'Overman', authenticity is the antidote to 'bad' nihilism.
