dhc There is still a problem here with understanding. You ask who determines the evidence. There are organisations that are concerned with determining what is good and what is bad evidence. For example : most western countries have a skeptics organisation. These are top heavy with good scientific brains, and are very concerned with evidence. I belong to one. They provide good literature and good guides to what constitutes good evidence. In addition, of course, good science is one of your best guides. For example : the issue of identity parades which I referred to earlier is written up in the scientific literature. I would recommend to everyone interested in science that they subscribe to, and read at least one scientific publication that delivers up to date scientific research results. A nice one, easy to read, which is reliable with its data, and free of charge is http://www.sciencedaily.com/ You use the term 'philosophical science.' This is pretty much an oxymoron. Science and philosophy are two quite different things, though it is possible to talk of the philosophy of science. There is no such thing as philosophical science, and most good scientists would do their best to demonstrate that philosophical issues are kept at a distance from their serious scientific work. Science is about empiricism. That is : about evidence gained from objectively carried out real world experiments and observations. While scientists often speculate, a good scientist knows that the speculation is not science. Only if a speculation can be verified by empirical testing does it enter the realm of good science. Speculation is not good evidence. Subjective experience is not good evidence. You ask me to be more tolerant of people. It is not people I am intolerant of. It is idiotic ideas. Yes, I am most intolerant about those, and so should all participants in this, or any other, science forum. If someone (and I am not talking about you) presents ideas that are based on bulldust, I will state most clearly that it is bulldust. Science gives us the clear cut guide to what is acceptable, and what is garbage. There are, of course, some people who will not respond to good data and good argument. I learned that decades ago. However, if good data and good argument is expressed on these forums, there will always be some people who will respond to them properly.
