“美”是一个二阶概念,是一种属性之属性,不同于我们通常理解的一阶概念。它是美的事物所具有的属性,也即审美主体与客体所形成的价值关系的属性。因此,美可以定义为:是人们的感官、心灵对事物所产生的一种精神愉悦的享受的价值关系的反映。 “Beauty ” is a second-order concept, which is an attribute of property, different from the first-order concept that we usually understand. It is the property of a beautiful thing, that is, the property of the value relationship formed by the aesthetic subject and the object. Therefore, beauty can be defined as the reflection of the value relationship between people’s senses and their enjoyment of spiritual pleasure produced by things.
