A newborn child does not have any concepts and knowledge, but he will slowly learn knowledge. This learning process is the process of gradually establishing conditional reflexes. For example, when learning to use chopsticks, he will be praised for doing it right and be punished if he do something wrong. There is no essential difference between this process and that of training dogs. The process to establish conditioned reflex is to strengthen associations of thinking. New conditioned reflex generate new associations that associate new stimuli (including images, words and sounds, etc.) with decisions, just as dogs associate ringtones with saliva. It produces science and technology to combine weeding and harvesting. Human complex decision-making, judgment, theory and social practice do not seem to have similarities to conditional reflex. In fact, all of these are complex conditional reflex.

The reflection of the cell phone in the mirror is totally different from the reflection of the cell phone in the human eyes. After seeing the mobile phone, people can associate and act, and can pick up the mobile phone, and the reflection of the mirror will not cause any association and operation. Wittgenstein believes that the meaning is to use.

The so-called understanding mainly refers to the association of thinking. When you are too close to a painting, you often don't understand what it is drawn. When you are far away, it's easy to understand. Because what you see closely cannot make you association. Sometimes when you hear a word, you will immediately nod your head, “I have heard of it.” Actually, you do not understand its precise meaning. For example, even if you do not know the definition of life, you can understand what life is because you can associate this word to many things. The more association, the deeper the understanding is. Generally when people say, “I do not understand”, he just means that he cannot associate. Every time you read a book, you will get a new understanding. This mainly means that every time some new association
