we all have ideas. and we have to back them. But equally I think we must be aware that our ideas may be wrong, that new information may come up, or something....?

What was it Cromwell said, consider in the bowels of Christ, perhaps you are wrong....something like that. He had a point. Not a lot of self knowledge, but a point!
