Friedrich Nietzsche on Psychology

"In Germany there is much complaining about my "eccentricities." But since it is not known where my center is, it won't be easy to find out where or when I have thus far been "eccentric." That I was a philologist, for example, meant that I was outside my center (which fortunately does not mean that I was a poor philologist). Likewise, I now regard my having been a Wagnerian as eccentric. It was a highly dangerous experiment; now that I know it did not ruin me, I also know what significance it had for me — it was the most severe test of my character."
