The aim of controlled scientific experiments is ______.
A.to explain why things happen
B.to explain how things happen
C.to describe self-evident principles
D.to support Aristotelian science
When we have told how things behave when they are electrified, we have told all there is to tell. Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand years, believed that man could arrive at an understanding of 'reality by reasoning from self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, hence one can conclude that objects fall to the ground because that is where they belong, and smoking goes up because that is where it belongs. The goal of Aristotelian science was to explain why things happen. Modern science was born when Galileo began trying to explain how things happen and thus originated the method of controlled experiment which now forms the basis of scientific investigation.

Today a student cannot master knowledge, he can only be its servant. He knows that he can become familiar (熟悉) with only a small comer of knowledge and that his learning will always be imperfect and imcomplete. But he can still hope to add something to the sum(总量) of knowledge, and so make the situation slightly more difficult for those who come after him.

D.in 1950--2000
听力原文: In science the meaning of the word "explain" suffers with civilization's every step in search of reality. Science cannot really explain electricity, magnetism, and gravitation; their effects can be measured and predicted, but of their nature is no more known to the modem scientists than to Thales who first looked into the nature of the electrification of amber, a hard yellowish-brown gum. Most contemporary physicists reject the notion that man can ever discover what these mysterious forces "really" are. Electricity, Bertrand Russell says, "is not a thing, like St. Paul's Cathedral; it is a way in which things behave. When we have told how things behave when they are electrified, and under what circumstances they are electrified, we have told all there is to tell." Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated western thought for two thousand years, believe that man could arrive at an understanding of reality by reasoning from self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, hence one can deduce that objects fall to the ground because that's where they belong, and smoke goes up because that's where it belongs. The goal of Aristotelian science was to explain why things happen. Modem science was born when Galileo began trying to explain how things happen and thus originated the method of controlled experiment that now forms the basis of scientific investigation.

The preceding passage placed you in the future. To understand how and when social science broke up, you must go into the past. Imagine for a moment that you're a student in 1062, in the Italian city of Bologna, site of one of the first major universities in the western world. The university has no buildings. It consists merely of a few professors and students. There is no tuition fee. At the end of a professor's lecture, if you like it, you pay. And if you don't like it, the professor finds himself without students and without money. If we go back still earlier, say to Greece in the sixth century B. C., we can see the philosopher Socrates walking around the streets of Athens, arguing with his companions. He asks them questions, and then other questions, leading these people to reason the way he wants them to reason (this became known as the Socratic method).
Times have changed since then; universities sprang up throughout the world and created colleges within the universities. Oxford, one of the first universities, now has thirty colleges associated with it, and the development and formalization of educational institutions has changed the roles of both students and faculty. As knowledge accumulated, it became more and more difficult for one person to learn, let alone retain it all. In the sixteenth century one could still aspire to know all there was to know, and the definition of the Renaissance man (people were even more sexist then than they are now) was of one who was expected to know about everything.
Unfortunately, at least for someone who wants to know everything, the amount of information continues to grow exponentially while the size of the brain has grown only slightly. The way to deal with the problem is not to try to know everything about everything. Today we must specialize. That is why social science separated from the natural sciences and why it, in turn, has been broken down into various subfields, such as anthropology and sociology.
