I have an urgent plea to scientists and all thinking people. We need to focus our attention on one goal, which will not be reached in the lifetime of the youngest among us but has to be achieved someday if humanity is to survive: That goal is the replacement of foolish faith and its vanities with something more sublime–knowledge and understanding that is securely based on observable reality.
Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world’s data. Theories are structures of ideas that explain and interpret facts. Facts do not go away when scientists debate rival theories to explain them. Einstein’s theory of gravitation replaced Newton’s, but apples did not suspend themselves in mid-air, pending the outcome. And humans evolved from apelike ancestors whether they did so by Darwin’s proposed mechanism or by some other, yet to be discovered.
