What philosophy now faces is no less than the reevaluation of all values. Let's break it down.
All of the genealogical history of philosophy has to be reapproached. We know we cannot rely on any interpretations before us, we take from the previous command only the conclusions which they themselves could not formulate. So a political philosophy, that is, the material action of philosophers, must make a collection of all the books and polemics, it must revive every strife that intelligent men engaged in. A library's first task would be to collect these works in a genealogical fashion in its first half, in its second half to promote the study of them. The important thing in the second half is that students don't seek either to study them as statues or to regress to the spirit that bred them, but to engage in the battles with their own spirit and free of all prior judgements, though not knowledge. This way, philosophy will no longer need to exist outside of tradition, wasting its efforts, to remain pure. The genealogical order is important, here already the seed of the new philosophy is planted.
Other philosophers will not be able to help in this, as they have found legitimate anchors already, but these will feed from the works of reevaluation and be tested by them. So extragenealogical thinking will stand at the end of the line for political philosophy to reapproach.
