Knowledge can improve human nature and experience can improve knowledge itself. Humanity is like wild flowers and weeds, and learning is like building transplantation. Although knowledge can guide the direction, it is often superficial and must be based on experience.
The purpose of reading is to understand the principle of things. Reading criticism is boring, but don't be too superstitious about books. The purpose of seeking knowledge is not to brag or show off, but to seek truth and enlighten wisdom.
Reading history makes people wise, reading history makes people wise, learning mathematics makes people precise, physics makes people deep, ethics makes people noble, logic and rhetoric make people able to contend. In short, "knowledge can shape a person's character".
Similarly, an inattentive person can study mathematics, because numbers will make mistakes if they are not careful; People who lack analysis and judgment can learn metaphysics, because this subject pays most attention to trivial dialectics; People who are not good at reasoning can study legal cases. These mental defects can be improved through study.
