It is an important tendency of modern western aesthetics to reconstruct art noumenon and explain art with form instead of social and cultural relations, but the methods adopted by various schools are different. Susan Langer used physiology (life science) and arnheim used psychology. Gestalt psychology believes that there is a corresponding relationship between the existing form of external things, human visual perception organization activities, human emotions and visual art forms. Once the ways of action of these forces in different fields reach structural consistency, it is possible to arouse aesthetic experience, which is "heterogeneous isomorphism" It is under the action of this "heterogeneous isomorphism" that people directly feel the attributes of "vitality", "life", "movement" and "balance" in the form of things and works of art.
meaning
The theory of "heterogeneity and isomorphism" comprehensively uses the methods of modern science, such as system theory, holism, cosmology, anthropology, physical field theory and psychological experiment, and explains people's aesthetic experience and the basic principles of art from a new perspective, which has its merits. It tries to transcend the opposition between subject and object, emotion and external things in western traditional aesthetics and establish an "isomorphism" in different fields. However, the influence and restriction of social historical factors and realistic factors on people's emotional activities and aesthetic activities are ignored or ignored, and the decisive role of human social practice and cognitive activities on people's psychological and even physical development is ignored or ignored. Therefore, it uses pure psychological and anthropological methods to explain the complex human spiritual phenomenon of "man" and "art". In this way, there is no way to talk about the relationship between art and human aesthetic experience. Even if people are restored to the original position of animals, they can't distinguish the difference between "people" and "non-people" because psychologists don't understand that the form of "five senses" is the product of previous world history.
