ka9q, from your earlier comments, it seems you think that the beliefs a scientist should have are those that can be empirically proven, and anything else is either hypocritical or delusional.
I can't speak for ka9q, but to me, empiricism (and deductive logic) is what science is about. I have yet to meet the scientist who believes only what has been shown empirically. I don't see anything remotely hypocritical about believing things which haven't been proven empirically, nor even in believing things which have been
disproven empirically, unless in the latter case one also claims to believe in empiricism. To reject empiricism in favour of belief is in my opinion wrong, but it doesn't sound hypocritical to me.
Delusional? I don't know. I know mathematicians who believe the Riemann conjecture is true, and I know others who believe it is false. None of them can prove their beliefs at this time (unless there has been some big news which I somehow missed recently), and they're all aware of this. If the question is one day resolved one way or the other, then we will know which group of mathematicians believed in the false delusion and which believed in the true delusion. (And this one isn't even an empirical question!)
Religious beliefs? Seems to me, it would depend on the particular religion. If your religion tells you things which contradict what we observe empirically, then you need to throw away your religion, or you need to throw away empiricism. If your religious beliefs are not falsifiable, then you won't ever face that dilemma. If your religious beliefs are in principle falsifiable, but haven't been falsified yet, then the day may be coming when you have to choose.
Deriving from that, they therefore should not cheer for one sports team over the other, or like a book, game, or movie over another, have a favourite food even. One could argue that they shouldn't fall in love with one particular person either from that premise as well.
The thing that I've noticed about internet faux-science boards is, the shriller the denunciation of religion, the more unproven (and unprovable) beliefs the denouncer seems to have. To me, whether we should want the Wallabies to beat the Springboks in the upcoming tournament is not within the realm of science. (The tournament itself could be viewed as a sort of empirical test about which team is better by a particular metric, but that's a different question.) My science is about understanding the laws the universe operates by. It won't ever tell me which team I ought to root for, whether Mozart is better than Beethoven, or anything like that. Certain types of science, psychology, sociology, et al., provide me with some tools I could use if I wanted to answer the question of how a society ought to be ordered, because they let me judge what the consequences of implementing some policy will be. But ultimately, the value judgement that tells me whether those consequences are good or bad, is not a scientific question. My science doesn't tell me what is good and what is evil.
Some seem to have a more all-encompassing version of science, that tells them what is good and what is evil. Rather like a religion.
Aggressively secular societies have done there own share of horrors. Just look at the 20th century, and likely earlier, so removing religion ain't suddenly going to make us angels.
That's just the thing, to me. How do we decide what is and what is not a horror, and which people are or are not angels? It seems to me that a person who claims only to believe that which can be demonstrated scientifically shouldn't even be asking whether something was a horror or whether someone is an angel. And yet ...
