Chris, I don' think I have misunderstood anything per se - I am posing questions - I am not saying that science should be the basis of morality, I was asking MDV if that was what he thought.
Fair enough, I could have worded that better; my mistake.
Also to say that my argument on the gay gene is unsound - to say 'Psychology is not a science' is to be a bit of a cherry picker to weed out things that give science a bad name, rather as Christian orthodoxy weeds out heretics from time to time. Clearly the cognitive science part of psychology is 'science' (it being based measuring things in brains and nerves), endocrinology is part of science and psychiatry is a branch of medical science.
No, it isn't cherry picking at all because there is a very clear criteria. Science (in it's strictest sense) is about explaining how things are, not how we would like them to be. Psychology, on the other hand, holds an ideal at it's core which has not been reviewed in hundreds of years, it classifies people according to their deviation from this ideal and attempts to 'fix' them if they deviate sufficently - this is not a Science. We have a further classification of 'soft sciences' which includes Psychology, Social sciences, computer Science, medical Science etc. which are subjects that use the tools and techniques of Science and approach their subject in a Scientific way, but they are not strictly speaking sciences. This idea is shared with most of the Psychological community and well as the Scientists, although there are people who disagree. If you choose to use a different terminology then fine, but I am not cherry picking anything. A more detailed account can be found here
http://www.arachnoid.com/psychology/index.htmlPlease note that by saying Psychology is not a Science I am not meaning to be derisive - it is a very useful field in it's own right and in any case my wife is a Psychologist, so I can't be derisive :-D
Furthermore, in the recent (20th century) past even a cultic theory like psychoanalysis was considered 'science' - it may have been dropped now, just as E=MC2 may be dropped in light of recent experiments, but it was still respectable science until recently.
There are no recent experiments that suggest E=mc^2 will be 'dropped'. I assume you are talking about the results from CERN that got anomalous results suggesting that neutrinos were travelling faster than light, but this was very badly handled by the media (as usual). First, there was no discovery made, these results have been largely refuted by further results from T2K and MINOS (as every Physicist expected, including the Scientists at CERN), and we expect a final result early next year. Secondly, even if these results did hold, this would not suggest that E=mc^2 would stop working - it's predictive power has been proven many times over, the most it would mean is a tweaking of relativity, not a replacement of it, in much the same way that relativity did not replace Newtonian mechanics, it just extended it.
All of these have had a go at finding a 'cure' for homosexuals - As to your scientific consensus that homosexuality has been seen as 'not against nature' for 'very long time' - I would disagree. It has been observed since the 19th century and there have been those that have argued it is part of animal sexuality that there was large disagreement about the topic until the 1970s. For the application in humans, see the timeline here: http://www.glreview.com/article.php?articleid=42 -
Again, that is from a Psychological point of view, and not a Scientific point of view. This mirrors quite well what I explained above about Psychology classifying people as a deviation from an ideal norm, and trying to 'cure' this deviation if necessary. From the Scientific perspective homosexual and bisexual behaviour has been observed in nature since at least the early 1800s and probably a lot earlier (it isn't my area of expertise), so I can assure you that Science has been aware that homosexuality is perfectly natural for a long time.
As to anthropology being an objective discipline not based on Christian teaching - there are two main branches of anthropology - physical/biological and social/cultural. The first deals with human evolution, so tells us little about morality and ethics (and has its own chequered past in the form of skull measuring racism), the second is a branch of sociological theorising based on the theory of cultural relativism (that also has a chequered past as an agent of colonialism and the search for the 'noble savage'). I have an MSc in anthropology and most of what was was done in anthropology departments when I studied it was the academic Marxist 'cultural critique' of the West's view that it is the natural order and of post colonial practices rather than anything 'objective'.
It sounds like you know more about Anthropology than me - I've never formally studied it, but I didn't mean to say it is completely objective, what I mean is that it is a MORE objective discipline than religion, and therefore it would make a better base for informing a common morality. Christianity comes at morality from the perspective of one group, and Anthropology combines other teachings that are relevant to all people, that is what I meant, but I might not have been very clear about that. Anthropology is informed by linguistics, evolution, etc. and so is surely more objective than one school of thought (christianity).
As to 'innate morality' - How can you test this scientifically without the interference of history and culture (including religion)? Clearly you cannot dump a group of babies on an island and watch them group up from a telescope. Last time I looked on the subject, the issue on innate morality is based on an extension of the Chomskian theory of universal grammar in linguistics. Which puts you back into the realm of those psychologists you deny are scientists. The experiments are based on taking young children and getting an authority figure to order them to override certain rules. The evidence being that they will override some (e.g. not spitting on the floor) but not others (hitting their neighbour). The criticism is easy to spot - perhaps the child fears reprisal (i.e. they have already learnt this fact before they went into the experiment). Certainly, army basic training performs an overriding of any 'innate' morality against killing all the time - so are the 'experiments' skewed? Can an 'innate' morality, if it is a fact of biology, be overriden as easily and as often as it has been in human history and really be classed as 'innate'?
I did say from the beginning that I don't know much about this, but I remember reading articles in New Scientist and such (okay, okay) which presented evidence that seemed reasonable, although I can't remember all the experimental controls. I'm a Physicist, so this is well out of my comfort zone, but I find it interesting even if I don't know a lot about it.
I won't go on - but there is also evidence from Protestant/Muslim parts Africa on HIV infection where condoms are available that HIV infection rates have either equalled or exceeded those of neighbouring Catholic countries. I know that the condom argument is used against Christians ad naseum but I think the facts may present some problems for some of these arguments on Africa and HIV infection and the blame attached to the Roman Catholic church.
The World Health Organisation published figures which disagree with you on this one, but I can't find the paper at the moment - I am trying to. You have to account for other factors such as the epidemiology of the area, etc. but what is clear is that using condoms will help to stop the spread of disease if used correctly; abstinence only will not help when you are telling someone with a biological urge to have sex not to. I'm not sure how you can disagree with this.
