审美活动是后实践美学的核心范畴。后实践美学把审美活动抬高到本体论的地位 ,一切美的其他范畴都由审美活动推导而来。这是美学研究视角的一大转换。美的个体性、精神性、超越性由此凸现。后实践美学对实践美学的超越还表现在对审美本质超理性的界定上 ,审美的本质不是理性与感性的矛盾运动 ,而是超理性形上追求。后实践美学主要吸收西方当代人文哲学的成就 ,在某些方面值得商榷 ,如对本体论的重设等 Aesthetic activities are the core category of post-practice aesthetics. Post-practical aesthetics elevates aesthetic activities to the status of ontology, and all other categories of beauty are derived from aesthetic activities. This is a major shift in the perspective of aesthetics. Beauty of individuality, spirituality, transcendence thus highlights. The transcendence of practical aesthetics to practical aesthetics also manifests itself in the definition of super-rationality of aesthetic essence. The essence of aesthetic is not the contradictory movement of reason and sensibility, but the pursuit of super-rationalism. Post-practice aesthetics mainly absorbs the achievements of contemporary Western philosophy of humanities and is debatable in some aspects, such as the reset of ontology, etc.
