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.
Letter to Carl Fuchs (14 December 1887).
