I Am a Strange Loop - Douglas R. Hofstadter [18]
What gives us word-users the right to make life-and-death decisions concerning other living creatures that have no words? Why do we find ourselves in positions of such anguish (at least for some of us)? In the final analysis, it is simply because might makes right, and we humans, thanks to the intelligence afforded us by the complexity of our brains and our embeddedness in rich languages and cultures, are indeed high and mighty, relative to the “lower” animals (and vegetables). By virtue of our might, we are forced to establish some sort of ranking of creatures, whether we do so as a result of long and careful personal reflections or simply go along with the compelling flow of the masses. Are cows just as comfortably killable as mosquitoes? Would you feel any less troubled by swatting a fly preening on a wall than by beheading a chicken quivering on a block? Obviously, such questions can be endlessly proliferated (note the ironic spelling of this verb), but I will not do so here.
Below, I have inserted my own personal “consciousness cone”. It is not meant to be exact; it is merely suggestive, but I submit that some comparable structure exists inside your head, as well as in the head of each language-endowed human being, although in most cases it is seldom if ever subjected to intense scrutiny, because it is not even explicitly formulated.
Interiority — What Has it, and to What Degree?
It is most unlikely that you, a reader of this book, have missed all the Star Wars movies, with their rather unforgettable characters C-3PO and R2-D2. Absurdly unrealistic though these two robots are, especially as perceived by someone like myself who has worked for decades trying to understand just the most primordial mechanisms of human intelligence by building computational models thereof, they nonetheless serve one very useful purpose — they are mind-openers. Seeing C-3PO and R2-D2 “in flesh and blood” on the screen makes us realize that whenever we look at an entity made of metal or plastic, we are not inherently destined to jump reflexively to the dogmatic conclusion, “That thing is necessarily an inanimate object since it is made of ‘the wrong stuff ’.” Rather, we find, perhaps to our own surprise, that we are easily able to imagine a thinking, feeling entity made of cold, rigid, unfleshlike stuff.
In one of the Star Wars films, I recall seeing a huge squadron of hundreds of uniformly marching robots — and when I say “uniformly”, I mean really uniformly, with all of them strutting in perfect synchrony, and all of them featuring identical, impassive, vacuous, mechanical facial expressions. I suspect that thanks to this unmistakable image of absolute interchangeability, virtually no viewer feels the slightest twinge of sadness when a bomb falls on the charging platoon and all of its members — these factory-made “creatures” — are instantly blown to smithereens. After all, in diametric opposition to C-3PO and R2-D2, these robots are not creatures at all — they are just hunks of metal! There is no
