Joseph McCabe Quotes

This is a very important quotation. It is usually quoted by opponents of evolution, but almost always, the last sentence is omitted. Evolution nay sayers often claim that the wing of a bird or the human eye could not have evolved in gradual steps, but almost all scientists do not agree, In addition, science has learned, since Darwin’s era, that gradualism, while generally the rule in evolution, is not always required in that mutations can create relatively rapid evolutionary change. So can behavioral factors like the dog evolving from the wolf which occurred in just a few generations. However, if there were found an organism that was created in seconds, doubt would be cast on parts of the evolution concepts. However, no one has established that. The best opponents of science have done to maintain their position is to offer complex animals and organisms they believe are too complex to have been created gradually, but they have not been able to scientifically demonstrate that there is a single one.

This quotation is a good example of what a substantial number of Americans believe and the classic errors they make in acting on their views. The vast majority of the religions in America have no conflict with evolution. To them evolution is the method that God chose to create the life on earth. Some fundamentalists take the Old Testament versions of the creation of the earth and man (there are 2 of them that conflict) literally by which they conclude that the earth is 6,000 years old or so. In reality, the earth is over 10 Billlion years old but the scientific evidence that proves this as well as evolution via natural selection is almost always not known to them. It is not as if they have studied it an rejected evolution. Almost all have never studied it. As a result they think that the word “Theory” means an unproven hypothesis which is the lay, non scientific meaning of the word. But in science, a theory is large set of related proven laws or principles, that has been tested over and over again and for which there has NEVER been a counterexample proven. A theory does not explain everything in the area and additional hypotheses are constantly being tested and if they stand up are added to the theory. And there are areas that are not explained by a theory, and these may or may not be in the future, but no theory does or can explain everything. Brattin, who sadly has never been educated about the science of biology, believes that it is a scientific theory is a “belief structure” like a religion. However, to qualify as part of an established scientific theory the statements must have been subjected to demonstrative proof, usually by many different scientists typically using many different methods. And these results must be replicated over and over again. No religion can be proved the way a scientific theory can be and that should not surprise anyone as religion is in the domain of faith where science has not the methodology to validate or invalidate people’s religious beliefs. Likewise, religion has not the methodology to prove or disprove science not should it be expected to. Many scientists are religious and many are not. Many religious people are scientists and many are not. They have little to do with each other.

Here the Governor makes a very common error of people who do not have scientific training. They believe that a Scientific Theory is an assertion that has not yet been proven. That is not the way scientists use the term. The Theory of Relativity, Theory of Quantum Mechanics and Theory of Evolution all scientifically refer to a major set of scientific statements and relationships that have been proven over and over again, together with many corollaries and deductions. It is an established, experimentally proven body of knowledge that is still producing additional hypotheses that then need to be proven or refuted. The scientific THEORY is as high as it gets on the scientific scale of proof. The word “theory” used in science is not one fact, but a large set of related facts and their proofs. What the Governor refers to, scientists call hypotheses or speculations. There have been many more proofs of evolution -–many thousands of them—than proofs of Relativity which is actually harder to prove and only has a few thousand proofs. More important, not one person has ever been able to prove scientifically that any of the assertions of evolution are false. Some religions have no difficulty with evolution (Roman Catholics for example) and a few do (fundamentalist Protestants for example). Governor Huckabee was also a fundamentalist Protestant minister. Even the Federal courts have held that the objections and so called “refutations” and alternatives to evolution are religious and not scientific, and hence may not be taught as science in public schools. Non evolution (like creationism) is a religious and cultural notion and should be studied as that.
