Human beings not only contemplate the meaning of the world,but also explore their own meaning in the world.Meaning always depends on humans.At the cognitive level,the physical,chemical,biological,and other regulations presented by objects cannot be separated from the scientific perspectives of humans examining.The relationship between people and objects is also related to the dimension of value,and the ecological significance of human existence naturally reflects the above value connotations.This meaning is not spontaneously manifested,but ultimately grasped and endowed by humans.The different forms of meaning involve different forms of existence.From the perspective of nature,objects have a distinction between being free and being human,and the change in their meaning is manifested as the transformation from a free existence to a humanized existence.In the social field,the significance of existence is related to the progress from disorder to order,which is reflected the harmony between people.Focusing on human consciousness and thought patterns,the problem involves different conceptual domains,including the unfolding of specific Shi(affairs/engagement).In the dimension of cognition,meaning focuses on understanding and comprehending the world(knowing reality);In the realm of value,meaning is aimed at realizing human ideals(seeking truth).The value connotation of meaning cannot be separated from the purpose.The purpose is first related to human action,which sets the direction of action and makes human behavior manifest as meaningful activities.In the process of interpersonal communication,it is necessary to pay attention to the role of dialogue.However,although dialogue endows communication with unique forms of meaning,it is more manifested as verbal communication,turning meaning into reality,and taking practical actions as a prerequisite.
