Re: [FRIAM] Wittgenstein
I would like to respond to Wittgenstein's idea that a mathematical proof should be called an invention rather than a discovery. When solving a Suduko puzzle, I often produce a logical deduction that the solution is unique. It seems clear to me that I discovered that there is only one solution. I don't see how to make any sense of the idea that I "invented" the fact that there is only one solution. "Wittgensteins technique was not to reinterpret certain particular proofs, but, rather, to redescribe the whole of mathematics in such a way that mathematical logic would appear as the philosophical aberration he believed it to be, and in a way that dissolved entirely the picture of mathematics as a science which discovers facts about mathematical objects . I shall try again and again, he said, to show that what is called a mathematical discovery had much better be called a mathematical invention. There was, on his view, nothing for the mathematician to discover. A proof in mathematics does not establish the truth of a conclusion; if fixes, rather, the meaning of certain signs. The inexorability of mathematics, therefore, does not consist in certain knowledge of mathematical truths, but in the fact that mathematical propositions are grammatical. To deny, for example, that two plus two equals four is not to disagree with a widely held view about a matter of fact; it is to show ignorance of the meanings of the terms involved. Wittgenstein presumably thought that if he could persuade Turing to see mathematics in this light, he could persuade anybody." Turing apparently gave up on W. a few lectures later. I have to admit the distinction that W. is making here does not move me particularly. It seems to me as much of a discovery to find out what is implied by the premises of a logical system as to find out how many electrons there are in an iron atom, and since logic is always at work behind empirical work, I cannot get very excited about the difference.

Re: [FRIAM] Wittgenstein

Well, what you're saying depends on your usage of your words, particularly the words "fact", "implicit", and "discover". But to answer as directly as possible, all you did was transform something some other person invented. So, yes, you invented the first sentence (the solution to the puzzle). And you invented the second sentence (the statement that the solution is unique). And you invented the string of sentences that "proves" the two previous sentences. The puzzle creator did not explicitly invent those two sentences or the string of sentences that constructs the proof. It's just like folding a piece of paper. Someone hands you a piece of paper and you fold it into an origami swan. Did you _discover_ the swan? Or did you invent the swan? I don't intend to play around with the definitions of words. But playing around with words is a _great_ demonstration of Wittgenstein's beef with platonic mathematicians. All they're doing is playing around with symbols. It's not science. It's symbol manipulation. There is no discovery in the same sense that scientists mean.

Russ, Oh, just that scientists appear to be one of the main violators of your self-awareness principle. Scientists tend to describe the physical world as if they are unaware that science constructs descriptive models of things far too complex to model, that might behave differently from any kind of model we know how to invent.

Re: [FRIAM] Wittgenstein
Or. another angle. Proofs represent discoveries about the invented grammar they use, with the proviso of "so far as we can see"? The way we define grammars changes to suite our intentions occasionally, but we're generally trying to identify things inherent in nature, for grammars drawn as conclusively as we know how to make them. They might not show us about the aspects of nature that are inconclusive, of course, but we still would like to know if our constructs are at least pointing to something real. What I find interesting is that every proof seems to imply "and therefore I can't think of anything else" a conclusion based on a lack of imagination. That point to proof as an acceptance of adding a branch to a constructed tree, I think? If the 'tree' itself at least reflects something that exists in nature when the grammar surely didn't is the puzzle. From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John F.

The more difficult the handling, the more one needs expertise. The simpler the processes, the more one can rely on yokels or algorithms. So, I think the opposite of your conclusion is justifiable: The more complex the processes, the more powerful the "skill set" sales pitch becomes because the customers are aggressively hunting for expertise. But even in a very complex domain, regular, somewhat predictable patterns of observation/manipulation can yield success, despite the occult possibility of unexpected wonky trajectories. And people who have those patterns of observation/manipulation down pat are also experts. They just run the risk of being wrong when/if the system does happen to take a wonky trajectory. There's no reason to avoid relying on historically successful patterns of control. You just have to accumulate enough momentum while successful to survive the black swans. The trick is that when experts sell themselves to you, they tend toward optimism (and underestimate the risks) because they don't eat their own dog food ... they won't really suffer the consequences the customer will suffer when their expertise fails. They _tend_ to promise what they really can't deliver ... or they're extremely vague about what they promise so they can hold up whatever they happen to deliver as a refined version of what they promised ... like politicians and outsource code shops. In contrast, if your "skin is in it", then you tend to be a bit more pessimistic (and conservative) with what you promise. -- glen e. p. ropella, 971-219-3846, http://tempusdictum.com FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org
Re: [FRIAM] Wittgenstein
Glen, You have made some interesting points. I don't deny that forming a proof involves invention and symbol manipulation. I also agree that mathematical truth is different from scientific truth. I now think the core question is whether a proof, according to the usual rules of symbol manipulation, represents a strong argument for the truth of the statement that is claimed to have been proven. (While, before reading your comments, my objections to W's statements were more a matter of whether "discovery" or "invention" is the better choice of a word to describe what is happening.) In other words, I see your interpretation of Wittgenstein's statements as his way of saying that mathematical argument does not do a good or reliable job of establishing truth.

On Tuesday night, October 7, journalist Tom Johnson will show workshop participants how to track data to their upstream sources. Web pages and their data are not static events; learn how to find the "signs" of where they came from, who owns the site(s) and sometimes who links to them. Johnson will discuss how investigators can use these attributes to advantage and also take a step back to consider the "architecture of sophisticated web searching." The third and final workshop, on October 14, will explore the payoff for the research done by the workshop's participants: following the money to see what and who is supporting the campaign. This final workshop looks at web sites that make it easier to follow the election money and focuses on how to get their data into a spreadsheet. Then what? A short intro to slicing-and-dicing the numbers. (Even if you are a spreadsheet maven, please come and act as a coach.) These workshops will give participants an opportunity to do some hands-on ("On-line hands-on", that is) investigation of New Mexico politics. Participants are also encouraged to bring a laptop if they can. After learning to do the online research needed to understand what's happening in the fall political campaign, participants will have the opportunity to do homework assignments and contribute to the Three Tuesdays wiki so their discoveries will be available to the general public.
