" The fateful law of human semiotics is this: that of all the objects in the entire Cosmos which the sign-user can apprehend through the conjoining of signifier and signified (word uttered and thing beheld), there is one which forever escapes his comprehension--and that is the sign-user himself...The self of the sign-user can never be grasped, because, once the self locates itself at the dead center of its world, there is no signified to which a signifier can be joined to make a sign. The self has no sign of itself. No signifier applies. All signifiers apply equally. "

― Walker Percy , Lost in the Cosmos: The Last Self-Help Book
