Okay, so maybe intelligence was the wrong word to use.
What de Chardin was trying to say is that sometimes, faith restricts us to one world view, and it makes us reluctant to accept any other view. But the statement "Faith is holding the intelligence to a certain world view" is rather ambiguous, so it could be interpreted in other ways.
And the point that was trying make here is that we should keep issues like these and religion separate. That's why I said that we shouldn't be dragging religion into this. I have nothing against religion, I just don't think it should be used to justify arguments here, because arguments that use religion are not rational, as they are based only on dogma.
And was abortion ever mentioned in the Bible? No. It wasn't. Sure, one of the Ten Commandments is "Thou shall not kill", but what about the girl? Wouldn't allowing her to continue the pregnancy be killing through negligence? Shouldn't her life be considered before that of the child, since she is the one who will be going through all the trauma of the pregnancy?
By the way, de Chardin was a Jesuit priest, although the other Jesuits didn't really like him (go figure)
