To begin with, logic and precise, careful measurement act as useful reference points in evaluating the advancements in many affairs of our life. One can look no far to find many compelling evidences, which strongly support this point. First, in education, the score that students achieve in the exam is regarded as the useful tool to judge how well they do in the lessons. And we can readily judge a student’s progress by checking the change of his scores, which were got during a considerable long period. The increasing mark means that individual has made nice progress. On the contrary, the decline in marks means the student’s retreat. Second, in the economy, the objective measurement is critical to judge how much a group makes the progress. For instance, GDP (Gross Domestic Product), acting as a statistical system, is usually employed to evaluate the economic condition of a nation. Here let's take the GDP of China for a specific example. The growth of GDP by 8 percent per year in the past ten years, which China has maintained, obviously shows the world that the economic condition in China is prosperous. Consequently, from these examples mentioned above, logic and precise measurement is an important element in evaluating.
On the second hand, it is a common sense to believe that nothing in the material world is thoroughly perfect. And it makes no difference in logic and precise, careful measurement. Namely, there are many situations where such evaluation does not work, such as evaluating the achievements of art, literature, and humanity. For example, can the price level of the painting of Picasso, one great artist, precisely evaluate the contribution of Picasso to human civilization? Does the increasing number of compositions indicate that we make substantial progress in literature? Does the growing frequency of crime illustrate that we are retreating in humanity, without the regard of fact that education is now accessible to everyone, which improve the humanity greatly? Without any doubt, the answer is no. Therefore, logic and precise, careful measurement can not be applied to show the progress of art, literature, and humanity.
In the third analysis, as far as our legal system and our democratic politics are concerned, progress and regress in these realms have little to do with numbers, or even logic. For example, can you say the number of laws represents the level of our democratic lives? From the American Constitution, which only contains limited number of laws, we can readily find the answer to the question is NO. For another example, does the phenomenon that everyone obeys the law sufficiently indicate that our legal system performances well and need no gradual modification? If the answer is yeas, then civil disobedience led by Marin Luther King, which aimed to fight against the Jim Crow Laws, will play no value. What a terrible consequence it is. So the evaluation mentioned by speaker does not work in politics. |
