Two main sources we gain knowledge from are books and practical experience. Some people think knowledge from books is more important than that from experience, others suppose practice brings about more necessary knowledge than books do. Clearly, each of them has its own advantages.
On one hand, knowledge from books effectively provides people with basic information about what they need for their life. If you want to know something about a country in the world, just take a book and read it. This way help you have comprehensive information about it without spending a lot of money on a trip. In addition, knowledge from books is cumulated from one generation to others, so this has formed an abundant and systematic depository of knowledge for human. If a scientist wants to develop a new theory or law, he must use available laws formulated by other scientists in the past. He can’t make out everything from the commencement. Therefore, it should be admitted that knowledge from books play an essential role in people’s life.
On the other hand, knowledge gained from experience bring about practical feelings of life. No one can cook a good meal just after reading a book teaching cooking. No one can swim after reading a book teaching swimming. No one can do business well after reading business and economics books. Almost all things you apply into your real life stem from your own real experience. You can know how to effectively solve your problems only when you have to face them yourself. In short, experience gives people hands-on and realistic knowledge so that they could deal with their real issues in their real lives.
In general, real life provide people with more necessary knowledge than books. People still can live well without reading many books.
