Argument for establishing the inner nature of appearances/representations Thanks!
more context: (although i am still trying to work out the "PSR part" too...)
"Suppose then, I (or anyone) am experiencing a field of representations. Within this field, I notice that a section of it, namely, my body, has a subjective aspect that is congruent with the very mind (that is, my mind) that contains the entire field of representations in which that body is located. Since my body is a representation, it is in my mind, but my mind also permeates and enlivens that very body from the inside. It does not, however, permeate and enliven the remaining representations in my perceptual field. Within this knotted context, Schopenhauer is struck by how incomprehensible it would be if the remaining representations in my perceptual field – the chair, table, knives, forks, etc. – were not also backed by a mentality similar to what I apprehend directly as underlying the representation of my body. Here is the same argument, formulated from a slightly different angle. From the subjective standpoint, every representation in my experience is “my” representation and is a mental entity. The representations are identical in this respect. From the objective standpoint, the representation of my body has a subjective backing, but since the other representations in my perceptual field do not display one, it is difficult to know whether they have one or not. The subjective backing to my body is my consciousness, and if – and this is the crucial point – there is to be a perfect parallel and consistency between the subjective and objective standpoints in general, as the root of the PSR would dictate, then the remaining representations in my perceptual field must have a subjective backing as well."
