“Science is not simply a matter of observing the world, experimenting with its elements and drawing reasonable conclusions. Otherwise, we would have to recognize children, so-called primitives and a good many animals as excellent scientists. But the practical experiments carried out by all of us every day lack a few necessary factors, the first and most important of which is the concept of the universe as a single entity operating under universal, rational, knowable laws. Without this foundation, science cannot operate as such.”
