实践转向与美学的逻辑

作为人文科学的美学，从实践转向的角度来看，其逻辑起点是人类社会实践，而人的存在只是美学的出发点。对应着实践结构的物质交换层、意识作用层、价值评估层、美学的逻辑结构应该包含着自然客体逻辑，即合规律性逻辑；人类主体逻辑，即合目的性逻辑；主客体关系逻辑，即审美间性逻辑。对应着实践类型的物质生产、精神生产、话语生产、美学的逻辑构成应该包含着物象逻辑，即感性形式逻辑；意象逻辑，即知性形式逻辑；形象逻辑，即理性形式逻辑。对应着实践的受动和主动相统一过程，物质和精神相统一过程，共时性和历时性相统一过程，美学的逻辑过程应该包括意向性活动逻辑，即对象化逻辑；超越性活动逻辑，即符号化逻辑；时空性活动逻辑，即真实化逻辑。美学的逻辑力量就在于实践的建构功能、转化功能、解构功能在审美实践和艺术实践中的实现。

Practical Turn and Aesthetic Logics

As humanities,aesthetic logical starting point is human social practice,and human existence is the only aesthetics intention.Corresponding to matter exchanging level,consciousness effecting level and value evaluating level of practical structure,aesthetic logical structure should include natural object logic that is logic of conforming to law;human subject logic that is logic of conforming to purpose;logic of relation between subject and object that is logic of aesthetic inter-subject.Base on matter production,spiritual production and discourse production of practical type,aesthetic logic constitution should include image logic that is perceptual form logic;imagery logic that understands form logic;image logic that is reason form logic.Corresponding to practical mutual integration course of passive and initiative,matter and spirit,synchronic and diachronic,aesthetic logic course should include intentionality activity logic that is objectification logic;transcendence activity logic that is signifying logic;time and space activity logic that is actualization logic.Aesthetic logical power just lies in the realization of practical constructive function,transforming function and deconstructive function in aesthetic practice and artistic practice.
