Sean, >>> To the extent that philosophy is commonly taught as being started by Socrates (knowing, of course, that there were pre-socratics), it was effectively ended by Wittgenstein. That is, Wittgenstein showed what the answers consisted of, and what techniques were required to silence the problems. The only reason philosophy-the-social-club doesn't understand this is twofold. (A) It doesn't have a Wittgenstein anymore (no one else can do it). And (B), it isn't good for business. It isn't good for business, that's clear, it makes all philosophers unemployed! Thank you all for this interesting discussion. I'd like to add a question, if it may enrich the topic. In the Tractatus, Wittgenstein does build theories, thesis and definitions - what is the general form of proposition, what are meaning and sense according to the picture theory of language, what is the relation between language and reality and so on. Nevertheless he goes beyond them and declares them to be nonsense in the famous closing propositions of the book. In the Investigations, he avoids the theoretical approach, by using perspicuos representation and family resemblances, which are means to the end of not theorizing but only show how we play in our linguistic games. Thus to analyse the meaning of a word is to see how it is used in the different contexts of the ordinary life. I think there are analogies and differences between Tractatus and Investigations on this point. It seems to me that 1. Both aim to show something instead of saying it; 2. Both perspectives risk to be self-contraddictory; 3. Investigations, using the new tools of perspicuos representation and family resemblancies, and inviting us to "look, not think", is better armed against contraddiction; 4. In Tractatus, the end is to see the world rightly; in the Investigations, what we get is, again, a vision, but this vision is intended to let us go back to our original and spontaneous life, in a pragmatic perspective that we can't find in the Tractatus. I'd like to know your opinions, if you like. Thank you Anna
