Klein, Jacob, A Commentary on Plato's Meno, Chicago: University of Chicago Press, 1965.

Must they not be based on a variety of preconceptions and predecisions, on a vast area of questionable assumptions and anticipations, perhaps more so than any other venture of our understanding? And is not, therefore, such an undertaking almost self-defeating? Whatever else it might require, it certainly demands, above all, awareness of the gravity of this problem.
