<p>Is it important to question the ideas and decisions of people in positions of authority?
That was experts said. is slang now. Almost everyone in the in the society has incline to trust the authority, considering that experts must have done enough experiments to confirm one object. However, in my opinion, authority is not the synonym to true; the spirit to doubt plays a vital role in the society. Science method, to some degree, is motivated by doubt: rather than accepting the existing theories, experiments with subjects continue. With skepticism, students who challenge the authority theories they have been taught can pave the science progress, just as Darrow once said: As long as the world shall last there will be wrongs, and if no man rebelled, those wrongs would last forever. And the history is replete with the examples.</p>
<p>William Davey, the sagacious English physician, challenged expertise human beings. About 1500 years ago, a resplendent doctor Galen once said that blood will disappear after circulate our body. Because of his preeminence, Galen was suspicion by any people at that time. During 1000 years later, no one stood out to naysay Galens theory; people all viewed him as gods emissary intransigently. However, 1000 years later, an English doctor Harvey first pointed out that Galen was wrong. After experiments with people and animals, Harvey found out that blood will not disappear spontaneously and the role of heart in repelling blood. With his discoveries, myriad patients were saved from the hand of death. At the same time, tons of troubles, never being solved before, was solved because of his theories. William Harvey laid the foundation of modern physiology. Without Harveys doubt, millions of people will pass away; without Harveys doubt, people may forever live in quagmire of falsity; without Harveys doubt, physiology will never develop so fast as it is now.</p>
<p>Another example is Einstein. When Isaac Newtons theories of action came out in 16 century, it was viewed as a natural rule. Everyone at that time accepted it without any hesitation, even those physicists who played a momentum role in physical history. Nevertheless, in 20 century, an American scientist Albert Einstein-the founder of theory of relativity-declared that the classic theory does not suit any condition, especially when the subject acts over the speed of light. Thus, people began to explain some problems of planet, driving force the discovery of universe. </p>
<p>The examples of Harvey and Einstein show us that the significance of suspicion. Doubt is the power not only pushing ahead physic but also pushing the whole humanity society.</p>
