To interact with our private languages it must gain access to what hitherto has been a shrine accessed by a priesthood order of one, ourselves. Art demolishes the privileged access maxim. Of course not. Rather it would be safer to assume that an object of art would mean different things to different people. The affinity provokes empathy and the latter is misinterpreted as understanding.
Art is as unintelligible as any other private language.
Yes, we are sealed off from ourselves as well. This is what we discover through Art. The echoes of our very own languages perishing in the caverns of our minds. The Guy Code Gothic.
