TOPIC: ISSUE153 - "Students should bring a certain skepticism to whatever they study. They should question what they are taught instead of accepting it passively."

I strongly agree with the assertion that students should bring a certain skepticism to whatever they study and question what they are taught instead of accepting it passively. The information is always increasing and the world itself is always changing, so it is necessary for students doubt the credibility of the former theory and knowledge.
In the field of nature science, this necessarity of being skeptical results from the limitation and development of the knowledge gained by human beings about the nature. Nature science is the subject learning the laws of the universe. Human beings, with a history of thousands of years, have only gained a small part of the information in the universe with a history of billions of years. Actually, as a part of universe, it is impossible for human beings learn all the information and the laws about the universe. There were are and will be some secret the universe hidding from human beings. However, with the research, explore and intelligent development, human beings are gaining more and more information about the laws of the universe. With the increasing information, it often occurs that what we believed to be the law of universe turn out to be not true, or more often, not so accurate as we once thought. So, the history of nature science is the history about doubting the former theories and creating new theories. Galieo chanllenged the belief accepted from the age of Aristotle that things would keep steady without outer force with inspire Newton to develop his theory about physics, which turned out to be extremely successful and accurate and regarded as an essential part of a proper education during the following centuries. However, at the begining of the 20th century, Einstein doubt the basic rules of Newton's theory, and developed the Relative Theory based on the results of some new researches, which replace Newton's Theory in modern scientific research. In a word, only with a certain skeptism to the already established theory can one achieve the success in creating new theory in the nature science field.
In the field of social science, this necessarity should be attributed to the restless changing society. The society is always changing from the age of caveman to nowadays. With the development of industrialization, the old ecomomic theory that established in the argriculture society cannot work any longer. Especially in the past century, the society and the lives of people has changed unprecedently rapidly, with the results of the technological advancement such as mobile phone and plane. Some old habits such as writing letters are becoming almost extinctive and some new phenomenon are developing rapidly such as Internet. Every change can diminish the meaning of the elder theory in social science field. The theory that fit the former society may not be adapted to modern society. So it is necessary for the students keeping a certain skeptism about the former theories which cannot be adapted to the society in the future and develop their own theories.
Someone are likely to question the meaning of doubting the basic precinples that are accepted by almost everyone. They may feel it is just a waste of time to doubt the basic pricinples and steadfast beliefs. However, the skeptism about the basic priciples are often the catalyst of some fundamentally new ideas. For example, it is well known that there is exactly one line passing by a point out of a certain line parallel to it. Acually, this is the fundament of the Euclid geography that established in ancient Greeke and accepted by almost everyone. However, it is the doubt of this anxiom that result into the found of teh Non-Euclid geography, which is the mathematical fundament of the Theory of Relativity.
In sum, students should have the courage to doubt whatever they study, at least in the field of two main branches of human beings' knowledge, nature science and social science, for the doubt of the already established theory has been proved to be the catalyst of great advancement in the history.
TOPIC: ARGUMENT186 - The following is a recommendation from the director of personnel to the president of Professional Printing Company.
"In a recent telephone survey of automobile factory workers, older employees were less likely to report that having a supervisor present increases their productivity. Among workers aged 18 to 29, 27 percent said that they are more productive in the presence of their immediate supervisor, compared to 12 percent for those aged 30 or over, and only 8 percent for those aged 50 or over. Clearly, if our printing company hires mainly older employees, we will increase productivity and save money because of the reduced need for supervisors."

In this argument, the arguer advocate that Professional Printing Company should hire mainly older employees in order to increase productivity and save maney spent on supervisors, because a recent survey finds that young workers are more likely to be more productive in the presence of their immediate supervisor. This argument suffers from several serious logical fallacies which make it unacceptable.
The arguer fails to convince us about the reliability of the survey. First, the survey is conducted via telephone. Maybe the supervisors are around the workers which prevent them to reply their real feeling. It is also very likely that there are some workers don't take such a survey seriously. Second, the there is no information about the size and the representivity of the sample in the survey. May be the people in the survey can represent only a small part among all workers which diminishes the meaning of the survey heavily.
The arguer commits the fallacy of false analogy. The arguer adapt the result of a survey of automobile factory workers to the priting workers without any demonstration. Actually, there are many difference between the automobile factory workers and priting workers. The priting workers can be more continent than the automobile factory workers, which makes the analogy between these two kinds of workers questionable. The work in priting company is also quite different from the work in automobile factory. Maybe the productivity is mostly influenced by the equipments of printing instead of by worker themselves. If so, the advocate of the arguer has little value for the company.
The arguer overlooks or intentionally neglects the other difference bewteen younger workers and older workers. The result of the survey reveals that older workers are less likely to be influenced by the presence of supervisor. However, this does not necessarily follows that the older workers are more productive than young workers. Considering young workers are more energetic, It is possible that young workers are always more productive than older workers, no matter with the presence of supervisor or not. There is also a possibility that the salary of older workers are higher than those young workers for an older worker is responsible to support a whole family. The older workers are more likely to get ill with aged bodies. If so, the decision of hiring mainly older employees will decrease instead of increasing the profit of the company.
In a word, with the flaws mentioned above, the arguer fails to convince us that Professional Printing Company should hire mainly older employees in order to increase productivity and save maney spent on supervisors. The arguer needs the result of a more credible and thorough study about the productivity of young workers and older workers with and without the presence of supervisors. |
