There is a close relationship between structure and function. Structure is the foundation of function, and function makes structure a concrete existence. Structuralists try to use structure to reveal the internal relations of society itself and explain some common social phenomena. They deny the existence of objective social laws, oppose the use of empirical research methods, oppose starting from specific things, and oppose summing up laws according to objective facts. They believe that structure is congenital and the result of subjective and objective phenomena.

(2) the structure of the unconscious:

Social structure is not only the sum of social relations in a specific society, but also the reality beyond empirical observation. It is a complete whole, composed of many elements, and the change of any one element is limited by the change of other elements. Therefore, the constituent elements of the structure are immutable and fixed. Social structure is the product of human inherent spirit, which is determined by heredity, not by society or culture. Therefore, the structure of culture is created by unconscious rationality.

(3) super rationalism:

Livingstone was deeply influenced by Marxism, geology and psychoanalysis, and the problem they faced was the relationship between rationality and sensibility. The goal of the three is to achieve a kind of super-rationalism, which integrates emotion and reason without losing its original characteristics.

(4) Simulation and structure:

Human cognition and behavior are deeply influenced by nature. Therefore, all human activities are the result of simulating various relationships in nature. The relationship network of "man/man" or "man/nature" is the structure. All animals have the ability to distinguish categories, and humans also have this innate, unconscious and instinctive simulation ability. Based on this ability, people have constructed many models based on binary opposition, which have become models of social culture and social relations. The simulation ability of human beings is manifested in the social customs and social relations of primitive tribes. The more developed the society, the more advanced the civilization and the more complicated the relationship, which may lead to imbalance. The task of structuralism is to reveal its basic structure from the seemingly complicated cultural and social relations, so that human beings and nature can regain harmony. This basic structure is a natural model of human rational unconscious activities and an algebraic model that human thinking must follow. Binary opposition:

Language is the foundation of social structure, and the structure of language is the prototype of social structure. The basic structure of all human languages can be simplified as the opposition between culture and nature. Based on this relationship, human language derives a set of concepts of binary opposition to refer to the relationship between different things. Structure must be characterized by relationships, and all relationships can ultimately be attributed to binary opposition. It can be said that every component or element in social facts, whether it is an event, an action or the naming and classification of natural phenomena in mythology, can be endowed with certain social value and significance according to its relative position in the binary opposition relationship.

(c) Structural analysis method: procedures mentioned in totem system.

1. Define the object we want to study as the relationship between two or more real or hypothetical projects.

2. Make a table and list the possible arrangements and combinations between these projects.

3. Use this table to analyze general objects. Only in this way can we get all kinds of relationships between projects. The empirical phenomenon that researchers initially considered is only one of many possible combinations. Only by building a complete system of these possible combinations can we see their structures clearly. Psychological algebra course:

All kinds of social relations and cultural variations we have observed are the results of human thinking ability running according to the program of psychological algebra. Levi Stowe compares the way the human brain unconsciously processes various symbols to the calculation process of matrix algebraic model, such as a simple matrix like a crossword puzzle. Taking symphony as an example, this paper explains that harmony is metaphorical and melody is metonymic, so as to understand and deal with the meaning of language or music.

(2) "Language" and "Speaking":

Language is a system composed of words, conventions and their usage. It is established by language users, not created. To speak and use words, we must select some words, grammatical rules, tones and stresses from the whole language system, arrange them in a specific order, and then speak words and convey information.

(3) "case system" and "meaning group chain":

The metaphorical usage of symbol constitutes the symbolic system of symbolic change; And its metonymic usage constitutes the so-called combinatorial chain, which refers to the abstract or formal connection between symbols and can express a complete information.

(D) The deep structure of myth:

From Levi Stowe's four-volume works on mythology, it can be found that he tried to put together a group of totems, rituals or myths obtained from different cultures, compare them with each other, sort out the paradigm system and metaphor model of symbol change, and determine whether the constructed model reflects the deep structure of human mind.
