Heraclitus - Footnote 7
7. The Kaufmann translation of the entire passage from Zarathrustra is "my wisdom has long gathered like a cloud; it is becoming stiller and darker. Thus does every wisdom that is yet to give birth to lightning bolts. For these men of today I do not wish to be "light", or to be called light. These I wish to blind. Lightning of my wisdom! put out their eyes." The Portable Nietzsche, translated and edited by Walter Kaufmann, Viking Press, 1954, 68, pp. 401.
