Faith is the great cop-out, the great excuse to evade the need to think and evaluate evidence. Faith is belief in spite of, even perhaps because of, the lack of evidence.
The meme for blind faith secures its own perpetuation by the simple unconscious expedient of discouraging rational inquiry.
The story of Doubting Thomas is told, not so that we shall admire Thomas, but so that we can admire the other apostles in comparison. Thomas demanded evidence The other apostles, whose faith was so strong that they did not need evidence, are held to us as worthy of imitation.
Faith can be very very dangerous, and deliberately to implant it into the vulnerable mind of an innocent child is a grievous wrong.
It is fashionable to wax apocalyptic about the threat to humanity posed by the AIDS virus, mad cow disease, and many others, but I think a case can be made that faith is one of the world's great evils, comparable to the smallpox virus but harder to eradicate.
It is an article of passionate faith among politically correct biologists and anthropologists that brain size has no connection with intelligence; that intelligence has nothing to do with genes; and that genes are probably nasty fascist things anyway.
I want to examine that dangerous thing that's common to Judaism and Christianity as well: the process of non-thinking called faith.
Oh, but of course the story of Adam and Eve was only ever symbolic, wasn't it? Symbolic?! So Jesus had himself tortured and executed for a symbolic sin by a non-existent individual? Nobody not brought up in the faith could reach any verdict other than barking mad.
Scientific beliefs are supported by evidence, and they get results. Myths and faiths are not and do not.
