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."
Something ,admittedly, having been adding to most of our observations making them subjective rather than purely objective. Just like in a football match, we may
wish the team standing for our country or our school to win, thus observation is not objective any more ,for it contains something emotional.And it is the same in the field of science. However it does not mean that we can not view something objectively, for we still have the sense and capability to avoid subjectiveness and try to be objective.
Naturally, our observations are always guided by our expectations or desires.Because we human beings can barely avoid being a little sentimental if not very. It seems that we have been used to the way we observe the world aroud us. For instance, we want the moving moive we watch to have a nice edding instead of a tragedy, which is for the nature of human being. Thus we are not objective anymore. And I think if we are supposed to watch objectivly all the time, the films especially featuring in its elaborate plot will no longer attract many moviegoers.
