TITLE: Language, and What It's Like To Be A Bat AUTHOR: Eugene Wallingford DATE: September 28, 2016 3:16 PM DESC: ----- BODY: My recent post about the two languages resonated in my mind with an article I finished reading the day I wrote the post: Two Heads, about the philosophers Paul and Pat Churchland. The Churchlands have been on a forty-year quest to change the language we use to describe our minds, from popular terms based in intuition and introspection to terms based in the language of neuroscience. Changing language is hard under any circumstances, and it is made harder when the science they need is still in its infancy. Besides, maybe more traditional philosophers are right and we need our traditional vocabulary to make sense of what it feels like to be human? The New Yorker article closes with these paragraphs, which sounds as if they are part of a proposal for a science fiction novel:
Sometimes Paul likes to imagine a world in which language has disappeared altogether. We know that the two hemispheres of the brain can function separately but communicate silently through the corpus callosum, he reasons. Presumably, it will be possible, someday, for two separate brains to be linked artificially in a similar way and to exchange thoughts infinitely faster and more clearly than they can now through the muddled, custom-clotted, serially processed medium of speech. He already talks about himself and Pat as two hemispheres of the same brain. Who knows, he thinks, maybe in his children's lifetime this sort of talk will not be just a metaphor.
If, someday, two brains could be joined, what would be the result? A two-selved mutant like Joe-Jim, really just a drastic version of Siamese twins, or something subtler, like one brain only more so, the pathways from one set of neurons to another fusing over time into complex and unprecedented arrangements? Would it work only with similar brains, already sympathetic, or, at least, both human? Or might a human someday be joined to an animal, blending together two forms of thinking as well as two heads? If so, a philosopher might after all come to know what it is like to be a bat, although, since bats can't speak, perhaps he would be able only to sense its batness without being able to describe it.
(Joe-Jim is a character from a science fiction novel, Robert Heinlein's Orphans of the Sky.) What a fascinating bit of speculation! Can anyone really wonder why kids are drawn to science fiction? Let me add my own speculation to the mix: If we do ever find a way to figure out what it's like to be a bat, people will find a way to idescribe what it's like to be a bat. They will create the language they need. Making language is what we do. -----
