If you are asking about authorship, there is nothing to ask. If you are asking about influences, I think care should be taken to understand the kind of intellect that Wittgenstein had. He was not a detail-oriented mind. He would have made a horrible lawyer. His basic industry was to take other people's thoughts and correct or clarify them. Imagine having a power of insight that was greater than others, yet not yourself really having your own answer. The idea would be that you could instantly identify the wrong answers -- the wrong paths of another's thought -- but you yourself cannot really have the "right answer." And this is because the same animal that sees through flaws in others stares straight down your own damn offerings. And so what you become is a man who takes the problems given to him and produces clarity in the manner that others working on those "problems" cannot. If we accept this as Wittgenstein's gift, we would find that whomever fed this machine whatever would wind up with a product sounding like the feeder's concern (which it was). Preface to the Tractatus: "How far my efforts agree with those of other philosophers I will not decide. Indeed what I have here written makes no claim to novelty in points of detail; and therefore I give no sources, because it is indifferent to me whether what I have thought has already been thought before me by another." There is some suggestion in the recent book, "The House of Wittgenstein," that one of the influences of the Tractatus was Tolstoy's, "Gospel in Brief." I had thought this book also mentioned that one of Wittgenstein's brothers may have influenced him somewhat. But I can't find that now, and I am wondering whether my memory on this particular point is in error. Regards. Dr. Sean Wilson, Esq.
