Of course, a wise man must have knowledge: only when he has knowledge, he must be able to make good use of it and constantly revise and increase his knowledge in the process of using it. Therefore, to say that a person has knowledge means that he really understands the meaning and utility of knowledge. Even if success is not one's own, the application and practice of knowledge is not a personal matter, but a collective undertaking that needs the long-term joint efforts of a group of people under certain social resources and conditions. From this point of view, knowledge is a sharp weapon for smart people, and it is by no means something that one person can monopolize; Knowledge is a social asset that everyone enjoys, because everyone has a certain degree of intelligence and has the opportunity to wander in the ocean of knowledge.
Secondly, smart people must be educated. Moreover, true intelligence is a sign of mental maturity, showing a person's due tolerance, taste and style. Now, we will always meet some people with knowledge and no culture; In fact, how can there be real knowledge without education? Knowledge and education are two aspects of an organic whole. It is knowledge that nourishes one's virtue. It is education that makes a person's knowledge play a real role, and at the same time shapes a mind and tolerance that is good at controlling oneself and understanding others. Especially in today's complicated life situation of interpersonal communication, we need to treat each other with a mature and open mind and wisdom, and constantly awaken and support each other with self-reliance and self-control education.
Finally, a wise man must have self-knowledge. Socrates is regarded as the most wise man in the world by the Oracle of the Temple of Delphi in Athens, because only Socrates admits that he is "truly ignorant", while other wise men always show off their omniscience. It turns out that an individual's intelligence is like a chestnut in the sea. How can you be arrogant under the omniscient and omnipotent god? And even if there is no god in our hearts, we must have great awe of the world; From the use of faculties to the use of understanding and reason to weave the outline of concepts, what have we grasped? Besides, there are storms between heaven and earth, and our hearts are always restless and unwilling to be lonely.
