散文:Science and the Scientific Attitude by Paul G.Hewitt

As the author points out below, the success of science has less to do with a particular method than with an essential attitude of the scientist. This attitude is essentially¹ one of inquiry², experimentation³ and humility⁴ before the facts. Therefore, a good scientist is an honest one. True scientists do not bow to any authority but they are ever ready to modify or even abandon their ideas if adequate evidence is found contradicting them. Scientists, they do place a high value on honesty.

Science and the Scientific Attitude by Paul G. Hewitt

Science is the body of knowledge about nature that represents the collective efforts, insights, findings, and wisdom of the human race. Science is not something new but had its beginnings before recorded history when humans first discovered reoccurring relationships around them. Through careful observations of these relationships, they began to know nature and, because of nature's dependability, found they could make predictions to enable some control over their surroundings.

Science made its greatest headway in the sixteenth century when people began asking answerable questions about nature — when they began replacing superstition⁵ by a systematic⁶ search for order — when experiment in addition to logic⁷ was used to test ideas. Where people once tried to influence natural events with magic and supernatural forces, they now had science to guide them. Advance was slow, however, because of the powerful opposition⁸ to scientific methods and ideas.

In about 1510 Copernicus suggested that the sun was stationary⁹ and that the earth revolved¹⁰ about the sun. He refuted the idea that the earth was the center of the universe. After years of hesitation¹¹, he published his findings but died before his book was circulated. His book was considered heretical and dangerous and was banned by the Church for 200 years. A century after Copernicus, the mathematician¹² Bruno was burned at the stake — largely for supporting Copernicus, suggesting the sun to be a star, and suggesting that space was infinite. Galileo was imprisoned¹³ for popularizing the Copernican theory and for his other contributions to scientific thought. Yet a couple of centuries later, Copernican advocates seemed harmless.

This happens age after age. In the early 1800s geologists¹⁴ met with violent condemnation¹⁵ because they differed with the Genesis account of creation. Later in the same century, geology was safe, but theories of evolution were condemned¹⁶ and the teaching of them forbidden. This most likely continues. "At every crossway on the road that leads to the future, each progressive spirit is opposed by a thousand men appointed to guard the past." Every age has one or more groups of intellectual rebels who are persecuted¹⁷, condemned, or suppressed at the time; but to a later age, they seem harmless and often essential to the elevation¹⁸ of human conditions.

The enormous success of science has led to the general belief that scientists have developed and ate employing a "method" — a method that is extremely effective in gaining, organizing, and applying new knowledge. Galileo, famous scientist of the 1600s, is usually credited with being the "Father of the Scientific Method." His method is essentially as follows:

1. Recognize a problem.

2. Guess an answer.

3. Predict the consequences of the guess.

4. Perform experiments to test predictions.

5. Formulate¹⁹ the simplest theory organizes the three main ingredients: guess, prediction, experimental outcome.

Although this cookbook method has a certain appeal, to has not been the key to most of the breakthroughs and discoveries in science. Trial and error, experimentation without guessing, accidental discovery, and other methods account for much of the progress in science. Rather than a particular method, the success of science has more to do with an attitude common to scientists. This attitude is essentially one of inquiry, experimentation, and humility before the facts. If a scientist holds an idea to be true and finds any counterevidence whatever, the idea is either modified or abandoned. In the scientific spirit, the idea must be modified or abandoned in spite of the reputation of the person advocating it. As an example, the greatly respected Greek philosopher Aristotle said that falling bodies fall at a speed proportional to their weight. This false idea was held to be true for more than 2,000 years because of Aristotle's immense authority. In the scientific spirit, however, a single verifiable experiment to the contrary outweighs²⁰ any authority, regardless of reputation or the number of followers²¹ and advocates.

Scientists must accept facts even when they would like them to be different. They must strive to distinguish between what they see and what they wish to see — for humanity's capacity for self-deception is vast. People have traditionally tended to adopt general rules, beliefs, creeds²², theories, and ideas without thoroughly²³ questioning their validity and to retain them long after they have been shown to be meaningless, false, or at least questionable²⁴. The most widespread assumptions are the least questioned. Most often, when an idea is adopted, particular attention is given to cases that seem to support it, while cases that seem to refute it are distorted, belittled²⁵, or ignored. We feel deeply that it is a sign of weakness to "change out minds." Competent scientists, however, must be expert at changing their minds. This is because science seeks not to defend our beliefs but to improve them. Better theories are made by those who are not hung up on prevailing²⁶ ones.

Away from their profession, scientists are inherently no more honest or ethical²⁷ than other people. But in their profession they work in an arena²⁸ that puts a high premium²⁹ on honesty. The cardinal³⁰ rule in science is that all claims must be testable — they must be capable, at least in principle, of being proved wrong. For example, if someone claims that a certain procedure has a certain result, it must in principle be possible to perform a procedure that will either confirm or contradict the claim. If confirmed, then the claim is regarded as useful and a stepping-stone to further knowledge. None of us has the time or energy or resources to test every claim, so most of the time we must take somebody's word. However, we must have some criterion for deciding whether one person's word is as good as another's and whether one claim is as good as another. The criterion, again, is that the claim must be testable. To reduce the likelihood of error, scientists accept the word only of those whose ideas, theories, and findings are testable — if not in practice then at least in principle. Speculations³¹ that cannot be tested are regarded as "unscientific." This has the long-run effect of compelling honesty — findings widely publicized among fellow scientists are generally subjected to further testing. Sooner or later, mistake (and lies) are bound to be found out; wishful thinking is bound to be exposed. The honesty so important to the progress of science thus becomes a matter of self-interest to scientists.
