Books are, in fact, recorded thoughts of other people. Such a seemingly banal, but very wise phrase was read by me once. This phrase sounded in the context of the need to seek your own thoughts and even write your own books. The advice, as a whole, is worthwhile, but, of course, not everyone is given the opportunity to write their own books. Moreover, it seems to me that not everyone is even actually able to always produce their own thoughts.
After all, the thought process is rather difficult and actually requires substantial concentration. Thinking work is no easier than physical labor, if done competently. However, most people are not particularly accustomed to think competently, this fact is easily confirmed by regular mistakes of people in the field of formal logic, duality of views and worldview.
Thus, if people read books, then they begin to join the culture of the thought process. Even if we are talking about some primitive fiction with simple heroes, such a book is still a product of intellectual labor. Accordingly, the reader looks at this product as a whole and catches some general structure and picture, from which he draws a certain conclusion, usually close to the one that the writer wanted to provide.
Also, the book is a good simulator for the mind, because reading concentrates the mind and allows you not only to absorb the thoughts of other people (that is, the author) but also to produce your own. Sometimes when reading you catch yourself (more precisely, your own mind) thinking about some completely distant topics. Then you recall how the plot created some associations and took the mind into the distance.
This example is an option when consciousness is not controlled. However, even in such a situation, a person eventually learns to track the various fluctuations of his mind.
Another option is when the thoughts of the heroes of the book, some plot moves make you consciously reflect on a particular topic. This option is a conscious concentration of thought, and that is how books are taught to think independently. In my opinion, this is the main task.
Books – learn to think. Yes, they are just thoughts of others, but sometimes it’s useful to find out what others are thinking.
