whether the information need to be shared freely to public People have different view about whether all the information should be shared without paying any money to public. In my opinion, while I accept that sharing information is convenient to people, I believe that some information need to be charge in a certain degree. On the one hand, sharing information to public is benefit to the development of some aspect of progress, such as scientific research and academic world. Students and professors can search the papers and references they need to use without spending a lot of money on booking the special scientific journal, especially when they have not enough scientific fund. In the same time, scientist will make the best use of this information to acquire the successful result faster than all the information keeps secret. On the other hand, some people argue that some information cannot be free to public because it is too vital. If some information concentrated on many people’s blood and sweat is open to public, it might not give them a great sense of satisfaction to their work and effort and it might be not equal to their endeavor. In addition, payment of something such as patent and literature can be done as a method of protection of their knowledge to prevent other people who want to copy the owner’s idea and thought with stealing author’s achievement. In conclusion, it seems to me that some information should be able to be shared with some payment so that the owner’s production, thought and idea will get their respect.
