How do you know that what is often presumed to be the key to the problem of induction, some alleged Scientific Method, is not a chimera and that this fact is a reason for the great difficulties in any big and complex scientific controversy. There is no clear enough Scientific Method to settle big and complex problems, the politics of it is not some mere separate matter. Relations between scientists, the whole practice of science cannot be easily separated from all politics. Sure it can be usefully separated from many of the barrows that various scientifically ignorant people are motivated to push. > >Now try to identify the > > *Scientific Method* and also, most importantly, *induction* in this > > particular context.

Personal invective, when not provoked by personal comments, are almost always a sign of this. Completely the opposite is the case of what you are saying (when stripped of your mean spirited attempt at clever insult). Scientific Method is quite central to this topic because in the history of this topic, many philosophers have seen in the idea of a Scientific Method a path to a solution to the problem of induction. -- dorayme

Brilliant, a self-confessed ignorant man comes forth to contribute with a reading list which he has not read. Well done, it is in the fine tradition of the other usenet guys here who do lots of quoting and telling people to go read stuff and implying great knowledge but never demonstrating any in personal invective free writing here and now. Oh, that would be just about too much for the people I am talking to, to actually read and understand the history of the problem and the literature. If they did, they might actually be able to discuss the topic more intelligently. But they constantly show that they are more interested in personal abuse and they brush aside any attempt to take things slowly and go through the ramifications of the problem. They are here to parade their abject ignorance and desire to beat people up. Look at the traffic if you don't believe me. Look at who starts insulting whom. -- dorayme

You *assert* that anything that is certain must be derived from sensory evidence. And that therefore "axiomatic certainty" is, by virtue of your assertion, a contradiction in terms. OK, let's take an example. Let's use Euclid's Fifth Postulate. Is that certain or not? PD |
