Healthy introspection, without undermining oneself; it is a rare gift to venture into the unexplored depths of the self, without delusions or fiction… - Friedrich Nietzsche

You have committed one of the greatest stupidities — for yourself and for me! Your association with an anti-Semitic chief expresses a foreignness to my whole way of life which fills me again and again with ire or melancholy. ... It is a matter of honor with me to be absolutely clean and unequivocal in relation to anti-Semitism, namely, opposed to it, as I am in my writings. I have recently been persecuted with letters and Anti-Semitic Correspondence Sheets. My disgust with this party (which would like the benefit of my name only too well!) is as pronounced as possible, but the relation to Förster, as well as the aftereffects of my former publisher, the anti-Semitic Schmeitzner, always brings the adherents of this disagreeable party back to the idea that I must belong to them after all. ... It arouses mistrust against my character, as if publicly I condemned something which I have favored secretly — and that I am unable to do anything against it, that the name of Zarathustra is used in every Anti-Semitic Correspondence Sheet, has almost made me sick several times.

Blessed are the forgetful, for they get the better even of their blunders.

Benefiting and hurting others are ways of exercising one's power upon others; that is all one desires in such cases. One hurts those whom one wants to feel one's power, for pain is a much more efficient means to that end than pleasure; pain always raises the question about its origin while pleasure is inclined to stop with itself without looking back. We benefit and show benevolence to those who are already dependent on us in some way (which means that they are used to thinking of us as causes); we want to increase their power because in that way we increase ours, or we want to show them how advantageous it is to be in our power; that way they will become more satisfied with their condition and more hostile to and willing to fight against the enemies of our power.
