Abstract: Body is the medium that connects the mind and the world,and it is also the form and material used in dance art.The dance body shows an ultimate "goodness" of dance art through the thinking evolution of "essence-way-value" in three aspects:the logic of generation,the pattern of expression and the shaping of beauty.The generative logic of the dance body is based on the observation of the body level,one of which is to present the material body as the real,and the other is to integrate the spiritual life into physical practice.Through the four expressions of body reproduction,body metaphor,inter-body nature and mind-body relationship,the "physical beauty","conceptual beauty","interactive beauty" and "self-consciousness" of dance art are generated in dance image,movement form,other relationship and self-consciousness,with the purpose to promote the construction of humanistic ecology with artistic body,sublimate character and purify humanity.

Key words: body, dance, dance body, body aesthetics, dance aesthetics
