TOPIC: ISSUE184 - "It is a grave mistake to theorize before one has data."


Whether it is a grave mistake to theorize before one has data should be taken into consideration. In the professional realms, some subjects should only build up the theory after mastering a great number of data while some are not. There are also some professions doing not need any data before. Thus, this statement above should be considered case-by case.

In many realms, data is the most basic part of a theory. It helps researchers figure out several trends, ideas and concepts of a certain phenomenon which contribute to the discovery. Without it, no theory can convince other professions and even the public. The volume of rain in every month in a certain area informs the weather scientists when a rainy season is. By this, we can analysis where the water comes from flowing by which kind of winds. As to the physic, Galileo discovered that the every subject drops from a high building in the same speed no matter how heavy it is. This was based on his famous experiment at the Leaning Tower of Pisa . From the data he collected he realized that the speed has no relationship with the weight after the subject was dropped from a tall building. From the examples we can tell how important the data is to a theory.

However, in some abstract sciences, it is hard for scientists to collect data before theorizing. It is possible for professions to make an assumption first and put it into practice next. If it can be turned out to be true in every condition, then, this assumption will become a real theory. For instance, in math, most theories were built up by assumptions at the beginning. The facts hide behind the trends so deeply that it is hard for scientists to conclude them from the data. Just after making an assumption, they will try them in different conditions. If in a condition this theory can not work, this one would be regarded as a false one. After hundreds or even thousands experiments, they claim they discover a theory. Thus, simply concluding that we should not theorize before data is not entirely right.

At last, data is not necessary in any realms. Only to the science, it can make great sense. While, when it comes to art and something else, data has no meaning at all. Can you imagine an artist theorize how to draw picture by judging by the number of different colors used? Can you bear the novels created by writers after they had exactly counted the words which can tell them whether the novel is perfect? The answer is definitely not. Art is what the artists are thinking, listening and watching. If they create music and picture based on data helping them judging the art, they can hardly make a big difference in their fields. So, the data is not necessary when theorizing the judgment of art.

In the final analysis, when people are studying in different realms, they ought to think about whether it is necessary for them to theorize before data. Also, as to art, the theory about how to judge a piece of work should not depend on exactly data. Anyway, people would better use the data in the most proper way instead of being controlled.
