Knowledge is infinite.

Only by fighting against the blue sky can the eagle know how vast and small the sky is; Only when the stream runs into the sea can we know how vast and small the ocean is; Similarly, only by learning more can a person realize that learning is endless, and the knowledge he has learned is just a drop in the ocean. French enlightenment thinkers also said that "shallow ignorance exists before knowledge, while learned ignorance exists after knowledge". It means "knowledge is endless".

Some people often don't want to learn. If they don't want to learn, of course, they rarely touch the unknown, and they don't know how profound and mysterious the unknown is. They naturally don't feel their own shortcomings, but feel that they are still very knowledgeable. It's like a frog at the bottom of a well, unwilling to jump out of the well and complacent. Jiang Yan, a writer in the Southern Dynasties in China, was famous for his articles in his early years and was known as "a talented man in the south of the Yangtze River". Later, he didn't want to continue his studies, and finally left a joke that Jiang Lang was exhausted. There is such a fable in ancient China, which tells the story of a Chu people learning to sail the sea. At first, his master taught him in calm water. After a few days, he was able to sail freely. So he thought he was "trying his best to sail" and didn't want to continue his studies, so he said goodbye to his master. Later, he sailed into the river, and the waves in the river rolled. He only ended up "looking around, stumbling, falling into the paddle and losing the rudder." This fable tells us that we can't find our own shortcomings without in-depth study, and we can't really master a knowledge.

On the contrary, learning will make people feel that they lack knowledge. The more they learn, the more they feel inadequate. The famous scientist Zhi Nuo once used a vivid metaphor to illustrate this truth. He used the inside of the circle to represent the knowledge he had mastered and the outside of the circle to represent the unknown knowledge. He said that the more knowledge a person has, the bigger the circle, the bigger the circumference of the circle, and the greater the contact with the unknown. So, he said to his students, "In this sense, I don't know more than you." It is this insatiable and enterprising scientist who has made brilliant achievements in science.

Learn and then know your own shortcomings, you must learn first and keep learning. Only in this way can you gain more knowledge and feel more about your own shortcomings. Only by never being satisfied can you keep learning and making progress. Mr. Lu Xun said: "Dissatisfaction is an upward wheel." Lenin said: "The most harmful thing is to think that we always know something." Pavlov said, "Don't think that you know everything at any time. No matter how much others value you, you should have the courage to say to yourself,' I have no knowledge.' These teachings tell us from different aspects that we should keep forging ahead and never be satisfied.

Zhu Youshi said: "Ask where the canal is so clear, because there is running water from the source." If knowledge is compared to the clear water in that canal, then learning is the source of knowledge. Only by learning endlessly, the source of knowledge will never be exhausted, and the clear spring water will flow out forever, watering the flowers of wisdom and bearing fruitful fruits.

Test analysis: first of all, we must understand that "shallow ignorance exists before knowledge, and learned ignorance exists after knowledge." There is a certain speculative color here. Shallow ignorance is because people have a narrow range of knowledge before they master knowledge, and they are vulgar in seeing problems and doing things. After mastering certain knowledge, although we have a certain thinking and a certain world outlook, knowledge is vast, learning is endless, and our knowledge is limited. At the same time, while gaining some knowledge, we have to stand the test of practice.

Reference angle:

1, the more knowledgeable (learned), the more you find your ignorance. /Knowledge is endless. The field of knowledge has increased its contact with the field of ignorance while expanding, and knowledge is deepening, advancing and expanding. At the same time, the more we know, the more we know about nature, the universe and life, and the more mysterious we are. In terms of cognition or people's mastery of knowledge, we may all have gone through such a path: not knowing what we know-knowing what we don't know-knowing what we don't know-knowing what we don't know. )

2. It is a kind of ignorance for a scholar to talk nonsense, cheat, whitewash peace, be self-righteous and stick to the rules.

3. When theory cannot be combined with practice, it is learned ignorance. Theoretical knowledge should also stand the test of practice. )

4. If you don't study, you are ignorant.
