“I once wanted to give a few words in the foreword which now actually are not in it, which, however, I’ll write to you now be-cause they might be a key for you: I wanted to write that my work consists of two parts: of the one which is here, and of everything which I have not written. And precisely this second part is the important one. For the Ethical is delimited from within, as it were, by my book; and I’m convinced that, strictly speaking, it can ONLY be delimited in this way.” (LvF, 94-95)

L. Wittgenstein
