Issue 157
There is no such thing as purely objective observation. All observation is subjective; it is always guided by the observer's expectations or desires.
In scientific world, there is no aimless observation. All observation is leaded by a certain goal or expectation. However, nowadays, people have already noticed that the subjective factors sometimes may affected the precise and objectivity of the result, so there are a lot of new methods and machines been developed to keep the observation objectively, yet we should also never forget that sometimes objective observation can only be useful with the guidance of a subjective mind.
People today have developed many effective methods to preclude the subjective factors in the observation. A case in point is in the medical field. Before a new drug can be put in to market, it must undergoing an clinic trial to test the effectiveness and side effort etc,. Doctors, as the observer in the trial, may have a subject opinion to the result that patients who take the drug definitely will recover better than those who take placebos, and so do the patients. So to preclude the subjective factors, people have developed a new method called "blind method" to control the trial. In the blind method, neither doctors nor patients know what medicine the patients are taking, the placebos and the drugs have the exactly same appearance, smell, and taste. The only one who know which are placebos and which are drugs are the one from the drag company who is not included in the observation. In this way both the subjective factors from patients and doctors have been excluded.(这里的例子可以证明你的分论点吗?)
To rule out the subjective factors, people also invented many new machines that can replace human observation. In the observation, different observers may have different conclusions, with the help of machine the subjective fluctuation between the conclusions of different people can be diminished. For example, in chemical experiment, people used to test the pH value by using pH value paper, which indicate pH value by changing into different colors. However, different observer may have quite different result. Red and dark red indicate pH 3 and 2 respectively, for a pH 3 solution, some people may claim that the pH is 3 because the color is red, but others may argue that the pH is 2 because they think the color is deeper than red. With the help of a new pH indicator, which detect pH by electric signals of the solution, the subject differences between people's sensitivity of colors can be eliminated, and a more precise result can be provided.(这一段和上一段意思上是否有些重复?)
Although more and more observations are becoming more and more objective, we should always remember that sometimes without the guidance of a subjective mind, the results of objective observation are meaningless. All the results of observation should be organized and arranged to found certain rules among them, and all these course can only be done under the lead of a subjective mind, that is a mind that with expectations and desires(我认为这个定义不好). For instance, people had began to record the observation of comet long time ago, however not until Halley began to consider the relationship between the record, those observers just simply wrote down time and location of the comets they found. Halley, after a thorough comparing of several observations, had found that some record had a similarity of period. He further induce that those records refer to a unique comet, the comet that is now well known to all-the Halley's comet. Without Halley's subjective hypothesis and expectation, the records of comets were just useless documents.(哈雷的例子很好,但是我觉得用在这里说哈雷是在带着强烈的主观感觉在做记录,好像不妥。相反,这个例子正说明哈雷不急躁,思路更冷静,沉着,客观。你觉得呢?)
To sum up, objective observation now is available by the use of new method and powerful machines, however the results of observation sometimes still need the guidance of a subjective mind.(我承认人的思想是主观的,但是不能这么忽略人的思想中忠实于事实的客观因素。就好比哈雷的例子,不能说明主观的重要性。可不可以这样说,同样哈雷的例子,你可以强调哈雷的Tenacity, 毅力品质等主观因素,我认为这比强调subjective hypothesis and expectation更能突出主观性,你觉得呢? )
总体框架很好。可是,论点阐发上好像深度不够。不知道你同意吗?
有人,这样开头,我觉得更深刻一些。
The speaker claims that all observation is subjective-colored by desire and expectation. While it would be tempting to concede that we all see things differently, careful scrutiny of the speaker's claim reveals that it confuses observation with interpretation.
