Some chatted for a moment and sighed in admiration. Even limited words feel unfathomable. Some people are also very powerful, but they have not been enlightened, and they are still almost mean. This feeling actually comes from a set of judgment criteria. What standard? Which level a person is at, forms his own logical closed loop. Some people may special database be "giant babies", standing on the "top of ignorance". Some may be true masters, constantly enlightened, standing on a "constant plateau". From the "top of ignorance" to the "valley of despair", tell me about my cognition worth tens of millions. Once wrote that there are about five levels to judge whether a closed loop is formed and what kind of closed loop is formed. The first level: thinking has no logic, thinking has no closed loop. You say A, he says B, there is no intersection between the special database two. Maybe he doesn't even understand what he wants to express, and the sentence itself has logical loopholes. The second level: thinking has logic, thinking has no closed loop. There is thinking, reasoning, and every sentence fits perfectly. But put all the words together, I don't know what to say, and the opinions contradict each other. What should a higher level of thinking look like? The third level: thinking has logic, thinking has a closed loop. But this closed loop, possibly a special database low-level closed loop, is a sad and terrible thing, because he may be standing on the "top of ignorance". For example, when confronted with conflicts, problems, and challenges, he likes to say that "yin and yang interact with each other", which has been the case since ancient times. "Why did the business fail, the yin flourished and the yang declined. Find to do it together, and you will succeed.
