Here is what Nietzsche wrote to a friend after deserting the Wagner cult:
Can you remain, in spite of everything, as kindly disposed to me as you were—or, rather, will you be able to do so? You can see that I have become so candid that I can endure only human relationships which are absolutely genuine. I avoid half-friendships and especially partisan associations; I want no adherents. May every man (and woman) be his own adherent only.
-Letter to Mathilde Maier, 15th July 1878
