I can certainly agree with you on all of that, Anna. In a way this is not what I am talking about. True - If maths could not predict change, then the armaments industry for one would never have arisen. Flight would never have become possible. Getting a satellite into orbit would be a fantasy not to mention the whole uncertain certainty of quantum probability measurement Math will usually cope with change when we assume a static background against which to measure something evolving. Some fields of math will even predict behaviour where no absolute background is assumed. We are getting better and better by the day at this kind of thing. I guess what I am on about is a bit closer to the 80s idea of "chaos" - something that is inherently unpredictable; at least if you adopt the stance of always launching your prediction from a single present - the one you happen to find yourself in. What I am asking is: can we RELY on mathematical reasoning to predict future outcomes with precision? Isn't this kind of like an act of faith? If we could perfectly model where things are heading then please tell me why all the BTSOAPs of the dismal science of the economics world could not arrange a more stable financial future for us than the one we are currently moving into? If mathematical modelling of alternative futures is so efficient Why is it that we can now see the inevitability of: water wars rising sea levels economic stagflation food shortages/riots runaway greenhouse warming endemic terrorism the catastrophic reduction of biodiversity to name but a few glowing futures ahead of us at this time. You cannot blame the politicians for everything. It is no use telling me that the politicians and the people in power are not listening to the number crunchers and that short term gain, political expediency and human greed are to blame. Problem solvers often complain that they have worked out ideal solutions but that no one will use the solutions. They complain that they have solved the problem brilliantly with their modelling but that the person or entity who has to carry through the solution refuses to do so. If this is the case, they have not solved the problem at all. Isolated problems are not real problems. Real problems include not only the specified problem situation but also the "person situation" which includes the people who have to accept and act on the solution. It may be better to have a suboptimal solution which everyone will accept rather than an optimal solution which no one will accept. Why for example, is humanity wasting its intellectual energy on this ridiculous argument about who or what is responsible for global warming? As if it would make any form of difference to the situation if someone were to "win" the argument. As David Deutsch said in his 2005 TED Talk, it was probably too late to do anything about it by the mid 70s of last century. We should be doing everything in our power to plan for living on a warmer planet. So what if Nature throws up these things - so what if mankind has buggered the planet - we still have to cope with the outcome! Just because I am right and you are wrong (or vice versa) does not make the problem go away. Humans seem to endlessly want to fidget about with logical argument because they believe (with Socrates) that all you have to do is remove all logical error, then what you are left with must be the truth. The "truth" is simply where our thinking ran out of puff. Something may well be academically "correct" (it takes two hours for two men to dig a hole five feet deep, so 10 men will dig a hole 25 feet deep over the same period) - but the simple fact is it probably WILL NOT TURN OUT THAT WAY!!!!!! (in the real, evolving, changing chaotically unpredictable universe) A car is driving down the highway. The car comes to a halt, having run out of gas. The people inside get out and dance about and congratulate each other on "having arrived at the destination". Truth is like that. regards, Kim --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
