Knowledge Gained from Books Some people believe that knowledge is always gained from experiences instead of books. However, I disagree with this statement because experiences could bring mistakes instinctively. Besides, books contain the complete content of knowledge and reduce the duration on trials and errors. First of all, it is possible to make mistakes by following past experiences, because current condition is not always the same as the former one. Sometimes you want to make things through based on your experience, but actually some instinctive errors have been involved. For example, I'm a mechanical engineer. I once encountered a problem which is regarded as a common issue as usual. However, after the force analysis precisely, I found out the solution still comes from basic theories in the book. Therefore, experiences are not always the right way to the goal. Second, books provide the complete and comprehensive knowledge base, while you can only learn some pieces of knowledge from experiences. Insufficient learning will not help you to solve the similar problems in the future. For instance, when I was a student, I used to understand all the material in textbooks before solving problems. By this method, I can easily answer all the questions in the same topic. Hence, one should gain knowledge from books rather than experiences for complete basis. Lastly, books teach you how to do by pioneer's methods, then it can speed up the process to solve problems. Newton said that he stands on the giant's shoulder and sees farther. That is, ancient people's experiences which all are written down in books can help us improve more and prevent struggling on the same traps. Take smart phone as an example, if people didn't take the cell phone and touch panel technologies as basic experiences, how can a smartphone contains both functions of calling and touch controlling now? As a result, we can learn more past experiences from books than our own experiences. In conclusion, because books contain the complete content of knowledge and reduce the duration on making mistakes, I'm of the opinion that knowledge is always gained from books instead of experiences.
