Will to Power #437 contains a marvellous discussion of Pyrrho of Elis. A taste:
A Buddhist for Greece, grown up amid the tumult of the schools; a latecomer; weary; the protest of weariness against the zeal of the dialecticians; the unbelief of weariness in the importance of all things. (tr. Kaufmann)
Years ago I noted the strange similarity of some arguments found in Nagarjuna and the late Pyrrhonist, Sextus Empiricus. (Memo to self: blog it!)
