Where angels no longer fear to tread ( The science of religion ) Part 1

By S K MONOHA of Cambodia, France.

Science and religion have often been at loggerheads. Now the former has decided to resolve the problem by trying to explain the existence of the latter.

By the standards of European scientific collaboration, Euro 2 m ( $ 3.1 m ) is not a huge sum. But it might be the start of something that will challenge human perceptions of reality at least as much as the billions being spent by the European particle-physics laboratory ( CERN ) at Geneva. The first task of CERN ' s new machine , the Large Hadron Collider, which is due to open later this year, will be to search for the Higgs boson-an object that has been dubbed, with a certain amount of hyperbole, the God particle. The Euro 2 m,by contrast,will be spent on the search for God Himself - or, rather,for the biological reasons why so many people believe in God, gods and religion in general.

" Explaining Religion ", as the project is known,is the largest ever scientific study of the suject. It began last September,will run for three years, and involves scholars from 14 Universities and a range of disciplines from Psychology to Economics. And it is merely the latest manifestation of a growing tendency for science to poke its nose into the God business.

Religion cries out for a biological explanation. It is a ubiquitous phenomenon- arguably one of the species markers of Homo sapiens - but a puzzling one. It has none of the obvious benefits of that other marker of humanity, language. Nevertheless, it consumes huge amounts of resources. Moreover,unlike language, it is the subject of violent disagreements. Science has, however, made significant progress in understanding the biology of language, from where it is processed in the brain to exactly how it communicates meaning. Time, therefore,to put religion under the microscope as well.

I have no need of that hypothesis
Explaining Religion is an ambitious at tempt to do this. The experiments it will sponsor are designed to look at the mental mechanisms needed to represent an omniscient deity,whether ( and how ) belief in such a " surveillance-camera " God might improve reproductive success to an individual's Darwinian advantage, and whether religion enhance, do people think that those who believe in God are more trustworthy than those who do not ?. The researchers will also seek to establish whether different religions foster different levels of co-operation,for what reasons, and whather such co-operation brings collective benefits, both to the religion community and to those outside it.

It is an ambitions shoppinp list .Fortunately , other researchers have blazed a trail. Patrick McNamara,for example,is the head of Evolutionary Neurobehaviour Laboratory at Boston University's school of Medecine. He works with people who suffer from Parkinson's disease. This illness is caused by low levels of a massenger molecule called dopamine in certain parts of the brain. In a preliminary study, Dr McNamara discovered that those with Parkinson's had lower levels of religiosity than healthy individuals, and that the difference seemed to correlate with disease's severity. He therefore suspects a link with dopamine levels and is now conducting a follow-up involving some patients who are talking dopamine-boosting medecine and some of whom are not.

Such neurochemical work, though preliminary, may tie in with scanning studies conducted to try to find out which parts of the brain are involved in religious experience. Nina AZARI, a neuroscientist at the University of Hawaii at Hilo who also has a doctorate in theology,has looked at the brains of religious people. She used positron emission tomography ( PET ) to measure brain activity in six non-religious ( though not atheist ) controls. The Christians all said that reciting the first verse of the 23rd psalm helped them enter a religious state of mind,so both groups were scanned in six different sets of circumstances ; While reading thr first verse of the 23rd psalm, while reciting it out loud,while reading a happy story ( a well-known German children's rhyme ), while reciting that story out loud,while reading a neutral text ( how to use a calling card ) and while at rest.
