Not true - you have frequently been asked for the methodology that supports your evidence claims: to date you have supplied neither.
Actually, I and others have provided such a methodology but, since folk like yourself regard anything that doesn't fit the scientific methodology that you espouse as non-method/non-evidence, of course you don't acknowledge the validity of such material.
That is largely why, in answer to bhs' "Are we done here?" thread, and many other similar threads, I have argued that we are arguing from two so distinctly different starting points that I wouldn't say that 'We're done', because I'm not sure that we've ever started. There has certainly never, in all the debates I've been involved with - both face-to-face and virtually - an argument put forward by someone arguing from your POV that has held water.
Do 'we'? Perhaps you'd care to list some of these, say 5 to start with, and we can explore them further.
OK, we take it for granted that some people will regard something as beautiful, but that others won't. I've heard several 'scientific' explanations for this, but none have been particularly convincing.
Then another is why 2 or more children brought up in the same way and in the same family rarely if ever hold exactly the same belief systems, attitudes and opinions. The nature/nurture' arguement is often rolled out in an attempt to explain this but rarely gives a satisfactory explanation - probably because the issues involved are too complex to reduce to such a process.
I have to go out for a while soon, so I'll leave it at that for now. Neither of these examples have easy answers - if they did, I think I'd have heard or seen them a long time ago. In my opinion, part of the answers come from aspects of human life that go beyond the scientific - that ask the questions about purpose and value.
