"Rejection of creeds is not inconsistent with being possessed by a living belief. We have no creed in science, but we are not lukewarm in our beliefs! The belief is not that all the understanding of the universe that we hold so enthusiastically today will survive in detail tomorrow, but a sureness that we are on the road. So too in religion, we are repelled by the sort of confident theological doctrine that claims to have settled for all generations just how the spiritual world works, but we need not turn aside from the measure of light that comes into our experience showing us a way through the unseen world. Religion for the conscientious seeker is not all a matter of doubt and self-questionings. There is a kind of sureness which is very different from cocksureness."
-Sir Arthur Eddington, Science and the Unseen World
