“The depth of knowledge to be gained from books is much richer and broader than what can be learned from direct experience.”
Books, a kind of media from which one can acquire knowledge, carry nearly all kinds of information. So, is the depth of knowledge to be gained from books much richer and broader than what can be learned from direct experience as the speaker claims? Actually, however, knowledge gained from books and experience is equally rich and broad for the following considerations.
The knowledge one can get from books is limited no matter how books contain knowledge abundantly. It is widely known that the life time for everyone can be no more than 150 years, and usually only 70 to 80 years. Even though one reads at the pace of one book per day(be not suitable for most people), the total books he can read is less than 6,000 books, and without obviating the years when one cannot read such as 1 to 3 years old. So the knowledge one gets is like a corner of an iceberg to that of books. Nothing is more ridiculous than to compare one's own knowledge with the total ones from books. Another important factor may limit one's knowledge is that we are forgetting knowledge everyday. It seems like a reservoir for a person's memory, whose cubage cannot be changed, if the water dimension going out exceeds that of the reservoir, the excessive water must be flown away, keeping the water amount in the reservoir all the same. In fact, the knowledge one forgets during his life is much more than that of he remembers.
Experience always can be the alternative to books for getting knowledge. If we experience something we have just learned from books, it can help us remember the knowledge, and the forgetting time can be diminished greatly compared to that of just learning from books without experiencing. The reason why experience has this function is that experience usually describe the knowledge with real ones that we can see or hear by our bodies, while on the other hand, books teach us knowledge using a relatively abstract way, which makes us frustrated and hard to understand. So we can get more impression when experiencing. Also, some knowledge got from experience cannot be found in the books. For example, there are so many skilled workers working in factories. They know exactly how to manipulate the machines and how to produce the products. However, they do not get the knowledge from books but other workers who worked earlier. The knowledge is all from experience, passing down from one generation to another.
Therefore, we should acquire knowledge both from books and experience, which may be a best way for learning. After studying from a book for some knowledge, then going out for experiencing the one we have just learned. Books can teach us new knowledge we have never contacted, and experience can make us more impressed by the real object that we can either see or hear. The effect of combination of the both two may be much better than only one of them. On no accounts can students ignore the importance of experience any more, while paying too much attention to the books.
In sum, both books and experience should be placed equal emphasis on, neither of which can be ignored. |
