Evolution is as much a fact as the earth turning on its axis and going around the sun. At one time this was called the Copernican theory; but, when evidence for a theory becomes so overwhelming that no informed person can doubt it, it is customary for scientists to call it a fact. That all present life descended from earlier forms, over vast stretches of geologic time, is as firmly established as Copernican cosmology. Biologists differ only with respect to theories about how the process operates. - Martin Gardner, "Irving Kristol and the Facts of Life", The Skeptical Inquirer, Vol. XII No. 2, ppg. 128-131 | |
HOW TO PROVE IT, PART 5 proof by accumulated evidence: Long and diligent search has not revealed a counterexample. proof by cosmology: The negation of the proposition is unimaginable or meaningless. Popular for proofs of the existence of God. proof by mutual reference: In reference A, Theorem 5 is said to follow from Theorem 3 in reference B, which is shown to follow from Corollary 6.2 in reference C, which is an easy consequence of Theorem 5 in reference A. proof by metaproof: A method is given to construct the desired proof. The correctness of the method is proved by any of these techniques. | |

My message is not that biological determinists were bad scientists or even that they were always wrong. Rather, I believe that science must be understood as a social phenomenon, a gutsy, human enterprise, not the work of robots programmed to collect pure information. I also present this view as an upbeat for science, not as a gloomy epitaph for a noble hope sacrificed on the alter of human limitations. I believe that a factual reality exists and that science, though often in an obtuse and erratic manner, can learn about it. Galileo was not shown the instruments of torture in an abstract debate about lunar motion. He had threatened the Church's conventional argument for social and doctrinal stability: the static world order with planets circling about a central earth, priests subordinate to the Pope and serfs to their lord. But the Church soon made its peace with Galileo's cosmology. They had no choice; the earth really does revolve about the sun. -- S.J. Gould, "The Mismeasure of Man" |
