According to the statement , studentsshould always question what they are taught but not accept it passively. It istrue that question the knowledge being taught is essential for many fields, butit would be presumptuous to question everything without careful thinking. Being skeptic is necessary especially for people who study science. Asthe theories brought up by predecessors are not always flawless, questioningthe validity and accuracy will certainly help them to find the defects andamend the theory. Consider, for example, the history of optics is filled with questions andamendment. After the geometrical optics was brought up, scientists questionedits validity because it can not explain the phenomenon of optical interference.Then wave optics was brought up to solve this problem, however , it stillfailed to explain optical reactions with several materials. In the end , aftercountless researches and observations, scientists created the quantum optics which explain thephotoelectric phenomenon perfectly.Without skepticism breakthroughs will certainlynot occur. It also apply to the artists , who always need unlimited imaginationto break the established forms and styles to make innovation. If they accept what has been taught passively, therewill not be masterpieces about art.
However, it is presumptuous to alwaysquestion what are taught by their teachers. As teachers are always more experienced than the students, theiradvices will undoubtedly be helpful for students as a guideline to avoid unnecessarybackwater. In fact, students should respect the opinions from their teachersbut not question them foolhardily. Besides, there are certain moral rules whichshould be obeyed since we were little when we lack the ability to identifybetween the evils and the goods. If we question these rules , it will only leadto the unsound development of our personal characters. In sum, it is necessary to be skeptic withthe reliability and validity of what are taught, but questioning withoutcomprehensive thinking will only lead to undesirable results.
