A Quote by Richard Dawkins
Even if there were no actual evidence in favor of the Darwinian theory, we should still be justified in preferring it over all rival theories.

Theories are not rejected by cirsumstantial evidence: it takes a theory to beat a theory.
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 while scientists debate rival theories for explaining them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air pending the outcome.
Evolution ... is really two theories, the vague theory and the precise theory. The vague theory has been abundantly proved.... The precise theory has never been proved at all. However, like relativity, it is accepted on faith.... On getting down to actual details, difficulties begin.
While control is needed, and perfectly warranted, our bias should be clear up front: Monopolies are not justified by theory; they should be permitted only when justified by facts. If there is no solid basis for extending a certain monopoly protection, then we should not extend that protection.
People sometimes try to score debating points by saying, Evolution is only a theory. That is correct, but it's important to understand what that means. It is also only a theory that the world goes round the Sun - it's just a theory for which there is an immense amount of evidence. There are many scientific theories that are in doubt. Even within evolution, there is some room for controversy. But that we are cousins of apes and jackals and starfish, let's say, that is a fact in the ordinary sense of the word.
Superstring theories provide a framework in which the force of gravity may be united with the other three forces in nature: the weak, electromagnetic and strong forces. Recent progress has shown that the most promising superstring theories follow from a single theory. For the last generation, physicists have studied five string theories and one close cousin. Recently it has become clear that these five or six theories are different limiting cases of one theory which, though still scarcely understood, is the candidate for superunification of the forces of nature.
Newton's theory is not 'not right', it just does not cover all distances. Contrary to popular belief, theories in science are not proven wrong, they are just replaced by more complete and convenient theories. To sound provocative, even the geocentric theory was never "proven" wrong, it is just not as convenient as the heliocentric theory, since it requires endless epicycles.
If we are uncritical we shall always find what we want: we shall look for, and find, confirmations, and we shall look away from, and not see, whatever might be dangerous to our pet theories. In this way it is only too easy to obtain what appears to be overwhelming evidence in favor of a theory which, if approached critically, would have been refuted.
Astrologers were greatly impressed, and misled, by what they believed to be confirming evidence-so much so that they were quite unimpressed by any unfavorable evidence. Moreover, by making their interpretations and prophecies sufficiently vague they were able to explain away anything that might have been a refutation of the theory had the theory and the prophecies been more precise. In order to escape falsification they destroyed the testability of their theory. It is a typical soothsayer's trick to predict things so vaguely that the predictions can hardly fail: that they become irrefutable.
I think the Republicans and conservatives generally were alienated by America's unsuccessful effort in Vietnam, and a lot of them, as Henry Kissinger admitted the other day, never got over President Nixon's impeachment, and didn't think, even though there was a pattern of illegal conduct there, sanctioned by the White House and proved by the tapes and other documentary evidence and testimony, they didn't believe that the impeachment was justified, and they didn't think he should have resigned.
Those who promote the politically correct theory are favored with billions from government grants and neo-Marxist environmentalist largesse, and official recognition and award. Faked and tampered data and evidence has arisen in favor of the politically correct theory. Is not man-caused, catastrophic global warming now the only theory allowed to be taught in the West?
Evidence-based reasoning underpins all scientific thinking, and it involves testing hypotheses or theories against data. Validating a theory requires replicable measurements from independent groups with different equipment and methods of analysis. Convergence of evidence is critical to the acceptance of a scientific idea.
Even facts become fictions without adequate ways of seeing "the facts". We do not need theories so much as the experience that is the source of the theory. We are not satisfied with faith, in the sense of an implausible hypothesis irrationally held: we demand to experience the "evidence".
When the theory of evolution destroyed the picture of God as the supreme Creator, confidence in God as the all-powerful Father of man fell with it, although many were able to combine a belief in God with the acceptance of the Darwinian theory.
It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,' and greater confidence in such a theory is certainly justified. There is less danger of going completely astray, particularly since it takes so much less time and effort to disprove such theories by experience. Yet more and more, as the depth of our knowledge increases, we must give up this advantage in our quest for logical simplicity in the foundations of physical theory.
There is a great deal of emotional satisfaction in the elegant demonstration, in the elegant ordering of facts into theories, and in the still more satisfactory, still more emotionally exciting discovery that the theory is not quite right and has to be worked over again, very much as any other work of art-a painting, a sculpture has to be worked over in the interests of aesthetic perfection. So there is no scientist who is not to some extent worthy of being described as artist or poet.
