I have said that only one thing exists and that is the personal or the relational. One might say that there exist only social relations. What then is the status of persons and other entities?
Persons are self-organizing collections of experience. Nothing can exist prior to experience, and only meaningful experience can persist. Meaning supposes intention, which conceptually polarizes into subject and object.
When I experience something the personal meaning of it possesses me. These meanings are held together by my own meaning. My meaning exists in my relation to others. Our only real need is for meaning and this is satisfied in many ways. There are only so many conceivable meanings and we are identical to the degree that we experience the same meaning. It is that commonality of meaning that holds our reality together. The depth of meaning has to do with the number of experiencers. Meaning has no content beyond the dynamic relations of its experiencers, and this is all that we experience through the identity relation. In this manner existence is entirely bootstrapped.
Admittedly, the patch of green in my visual field seems nothing like a structure of social relations. That is the problem with sense data; they keep getting in the way of reality, but where would reality be without the data. Does the song exist for the notes or the notes for the song? Since there are notes there can be many songs. The single note is perhaps the nearly meaningless (?) intersection of all of its songs; an orphan begging for yet another song.
We distinguish between the sign and the signified, but if the world is a symphony, where are the signs? Combinatorics allows there to be a common current on whose waters we are but ripples. O.K., solitons then!
