From the level of science, the light we saw is the reflection on objects, and that are not the objects themselves. The space that we apperceived from the vision is the result of the interaction between the light and objects, therefore, there is some internal relationship between the light and objects, which means there is correspondence between them.

从科学意义上讲，我们看到的是光线在实体上的反射，而非实体本身，我们视觉感知的空间是光线与实体相互作用的结果，因此光与实体存在着某种内在的联系，也就是说，光与实体存在着对应性。
