Riff on Clausnitzer esthetics

Having visited the essay on his website Rough Trade & read the hard thought therein about the contribution realism could make to abstract painting, I was inspired by the article to parasitize and assimilate (probably wrongly) some of the thinking I found there to my own philosophical prejudices...Whitehead's theory of perception is that the senses are not primitive graspings of the real at all, rather, they are very precise and refined indices of the real world that, like computers, are supremely precise, except when they aren't, i.e. when they get a glitch at some basic level of functioning...in Whitehead all the senses are refinements of a direct grasping of the universe that he calls "prehensions." Basic prehension as such is supremely vague but is in its way more reliable than so-called sense data. (An example of basic prehension, prior to all information from the senses, is the sense, say, of being a localized entity...) A prehension is a direct grasp of all the immediate entities contiguous to the experiencing entity in time and space (this is not precise Whiteheadian language at all, because time and space are also, er, things, that are built up rather than being foundational, but for the sake of time and a certain rough and misleading clarity, I'm leaving that for the moment...) A prehending entiy's grasp of another entity also indirectly prehends all the entities prehended by the other entity, etc. ad infinitum...thus a prehending entity to a vanishingly small degree prehends the entire universe...Now, my favorite French philosopher, Giles Deleuze, warns against the project of trying to subsume all of art under a single theory...in his view each of the arts has a certain sphere that is irreducible to any of the others...yet he would likely admit that the cross-fertilization and boundary mergings can be fruitful ways to proceed...by a process of analogy from Whitehead, if something is expressed as visual image is borne along on the back of a more primitive prehension, then the more primtive prehension can also be assimilated to an expression in another perceptual mode...of course, that is a gross oversimplication...a great deal is lost in de-translation and re-translaton in such a context...yet it could account for how it is possible to find relatonships and analogs among the various arts and at the same time not threaten the autonomy of any...& maybe has some bearing on phenomena such as synesthesia...
