Evidence precedes Dogma
No idea is permanent
No idea is necessary
All ideas are in flux as new evidence and new ways of thinking arise
I believe in evolution. I do this knowing the evidence for and even the "evidence" against. Contrary to popular opinion I have the ability to change my mind if I were presented with true evidence. This evidence will lead to a new belief which will not paint me into a corner: "Doubt ye this and be thou damned to Hell." The new belief will be Scientific, Naturalistic, testable, and useful.
Very quickly… The usefulness of evolution: comparative oncology / medicine. Geneticists are studying breeds of dog in order to find what cancers manifest in what breeds to find genetic markers for that cancer. If evolution is true, then we are kin to dogs and this is a worthwhile thing to do. If evolution is false, we are made special and unique in God's holy image, then we are alien to other animals / mammals and this is a waste of time. But the question must be asked, Why are medicines first tested on lab animals then humans?
