The decisive point, however, is this. The second presupposition of a fruitful discussion between them and me would have to be that we are able to talk on a common plane. But these people have already had their so-called orthodoxy for a long time. They are closed to anything else, they will cling to it all costs, and they can adopt toward me only the role of prosecuting attorneys, trying to establish whether what I represent agrees or disagrees with their orthodoxy, in which I for my part have no interest! None of their questions leaves me with the impression that they want to seek with me the truth that is greater than us all. They take the stance of those who happily possess it already and who hope to enhance their happiness by succeeding in proving to themselves and the world that I do not share this happiness. Indeed they have long since decided and publicly proclaimed that I am a heretic, possibly the worst heretic of all time. So be it! But they should not expect me to take the trouble to give them the satisfaction of offering explanations which they will simply use to confirm the judgment they have already passed on me.
