Most people usually are learning and practicing through their whole lives. From reading words in text book such as toy, car and train, people have the concepts and ideas. They more understand the actual meaning of these words by playing toys and riding or driving cars, trains. Education from books and experience are the main two point for People to gain their knowledge. Each play different roles for people. But I agree knowledge from experience is more important than that from books.
To begin with, Experience first can prove whether the knowledge form books are true or false. Textbooks are very wonderful in teaching people essential principles, how is the world looks like? what is the basic law of change of people and things? We can learn many things through primary school, secondary school until entering university. But people can only understand the really meaning of form books and justify them if they are right through practices. A few hundred years ago, people learn from text book that the earth was flat. However scientists found that was wrong through observations and measurement.
Another reason is that the knowledge from experience can improve and advance our society. As books limitated, they only teach us the what people found in the past. The knowledge from the books are constrained to the certain conditions and environment. For example, mould and tools design of plastics industry, the university course only taught me very simple cases, most knowledge are obtained from various different and complicated cases in my career.
Finally, there are a lot new inventions and new products which could not be found from textbooks. Our society and world are developed through continuous practices. So those knowledge never found in books like internet, e-business. those are all developed through new practices.
“The truth comes from practices and experience”, people are continually discovering new things and assessing the creditability of the knowledge written in books. The knowledge from experience help us much more than those from books.
