Tim: "From that "I don't know," comes forth a truer knowledge"

Well said. A "truer knowledge" comes forth when the 'god-of-the-gaps' has been dispensed with.

A creationist when asked by one of his fellows, "How were the dinosaurs rounded up for Noah's Ark?" replies: "God did it". And so it has been with so much of religion through the ages. What is worse, the mythology is enshrined as sacred 'truth' that forbids contradiction and preserves ignorance.

At a meeting of scientists entitled "Beyond Belief 2006", one young fellow said that he very much disliked not knowing; to which many responded that they very much liked not knowing. - Two ways of expressing the same essential point, that 'not knowing' is what drives the advancement of knowledge.
