What do you mean by abstract and concrete?

Abstraction is a method to reproduce the quality and essence of an object in the human mind through analysis and synthesis, which can be divided into qualitative abstraction and essential abstraction. Analysis forms qualitative abstraction and synthesis forms essential abstraction (also called concrete abstraction). As the starting point of scientific system and people's complete understanding of things, it can only be an essential abstraction (concrete abstraction). The abstraction of quality can only be a link in the essential abstraction, not as a complete understanding, nor as the starting point of a scientific system.

Figurative is a Chinese vocabulary, pronounced as jù xiàng, which is concrete but not abstract when used as an adjective; When used as a noun, it expresses a concrete image; It is the basic image that is active in the minds of writers and artists in the process of literary and artistic creation. It is also the basic requirement of literary and artistic creation. Scholar Chang Zhiguo's couplet In Jing Tang: "Dunhui Heart Official Figurative/Cloud as Quality Revival" emphasizes the importance of figuration in creation.

Representatives and statements:

Representation only keeps the image of something in memory; Figurative is a colorful and highly concentrated image that writers and artists have been in contact with and excited about many times in their lives. It is not only the result of perception and memory, but also bears the emotional imprint of writers and artists and is processed by their thinking. It is a combination of countless single appearances in life and formed after making choices. Psychologically speaking, the creative process of literary and art workers is a concrete movement process. The concrete movement process is mainly a process of stimulating and strengthening the emotions of writers and artists and interacting with them. Once entering the stage of figurative movement, creators often can't help themselves, even crazy, unconscious and rarely controlled by abstract thinking. Concrete is not the starting point of abstract thinking, but the result of selection and comprehensive representation under the action of abstract thinking.

Genetically speaking, image and memory ability are people's low psychological level, and animals also have image and memory ability, but animals do not have the ability to comprehensively choose images according to their own needs, attitudes, experiences and ideas, and then form concreteness, which is unique to human beings.
