On page 129 on of After Virtue (2nd ed.) MacIntyre writes:
Here again it is clear that Nietzsche had to mythologize the distant past in order to sustain his vision. What Nietzsche portrays is aristocratic self-assertion; what Homer [portrays are] the forms of assertion proper to and required by a certain role. The self becomes what it is in heroic societies only through its role; it is a social creation, not an individual one. Hence when Nietzsche projects back on to the archaic past his own nineteenth-century individualism, he reveals that what looked like an historical inquiry was actually an inventive literary construction.
Good point. This does not necessary invalidate Nietzsche’s project, but it demands that here (as also with Heidegger on Aristotle) one be clear on the artistic nature of it.
