I have a purple shirt, or maybe it is royal blue. I was never in doubt about the color until my wife called it blue one day. Up until that point, I never even contemplated calling the shirt blue, or that there might be a difference between my perception of the shirt’s color and her’s.
Maybe there still is not a difference. Maybe our perceptions are the same and the words we use differ unnecessarily. If I look hard, though, I can see how she would call the shirt blue.
Her and my perceptions are almost certainly not the same, nor are anyone’s. The alternative – that people disagree about colors, and so much more, because our language is massively mistaken – seems too incredible. Shouldn’t we have ferreted out even the most minor issues by now? After all, we do so well at finding agreeable words for so many things, even in the realm of aesthetics.
Plus, there is a good explanation for the source of disagreement between me and my wife on my shirt’s color. If one tracks back how each of us learned to classify blue and purple experiences, there are substantial differences. And, those differences do not only effect our use of words; those differences also condition our purple and blue perceptions .
Yet there is another problem lurking. Even if I could magically take a snapshot of my brain at the moment in which I saw the shirt as purple, and show it to my wife, not as a map or photo, but as exactly the same state of affairs imposed upon her neurons, she could still differentiate it upon reflection. The brain state in question would always be her experience of my experience, rather than simply her experience. My experience of the shirt’s color cannot be captured, as mine, by means of physical reproduction.
One might ask, who cares? The upshot of our limitations is tolerable. Big truths may be a little counterfeit by implication, but we are accustomed to working with flawed notions already, and do fine by it. For example, Newtonian mechanics serves us beautifully, even if it is not ‘really true’.
Yet, we do not tolerate our flawed notions. An optimist would say that we are not satisfied with lesser things, and are constantly trying to improve our understanding. Our behavior suggests otherwise, however. We want big truths in principle, and the certainty, the reality, that comes along with them. In physics, we don’t just want quantum mechanics and relativity, we want a theory of everything. In ethics, we want good and evil, and duties to serve.
So, the hard problem does matter, because it is motivating. And, it moves us to a harder problem. We want things to be true which are not merely false, but which are incapable of being true or false. The idea of a concept not being truth-apt is slippery, so an illustration is in order.
Consider the case of Baby K. Baby K was born over two decades ago without a brain. Not only was she(?) born, she pulled off a feat which few anencephalics manage; she lived more than briefly. Or, she maintained a metabolism more than briefly, because her status as a living thing, much less a living human infant, was in question. She would never see a purple shirt, or a blue shirt, or have any experience at all. And since our personal experience is what we value above anything (what choice do we have, after all?) some people felt that a creature without experience and incapable of it was not truly alive, much less human.
Baby K’s mother disagreed. She felt that K was born of a human, exhibited some behaviors, had a heartbeat, and therefore fit into the human peg-hole, albeit imperfectly. K’s remarkable persistence owes to her mother’s insistence on aggressive medical interventions for K, based on K’s status as a human baby. For K’s mother, the rules of classification were categorical. There are Forms in the world, according to this school of thought, and the Forms suck their creatures in, even the most flawed copies.
When Baby K had trouble breathing, her mother took her to the ER and demanded that Baby K be saved, put on a ventilator, and nursed back to health in the ICU. But was health one of K’s capabilities? She needed saving, but for what, and from what? We could not ask K about any of this, ever, even in principle. As her physiology counted down to its end, what was there to distinguish this tick from the following tock, and so provide a basis for valuing more of the physiological process?
When K came in to the ER, the professionals on duty did not want to treat her. Since she was incapable of experience, she had nothing to value (there wasn’t even anyone there to value anything). Efforts to ‘help’ K were therefore empty. There was nothing to help with and no one to accept the helpful gesture.
Remarkably, some argued that further medical interventions merely prolonged K’s suffering. Perhaps they meant to say that further interventions caused the staff to suffer. More properly, futile actions degraded the integrity of the medical professions. We become what we practice, and if the medical professionals practiced service to the beating heart, then they rightfully feared that they would become servants to the beating heart.
The hospital also expressed concerns about the resources that K consumed. This argument was a utilitarian argument and failed in the usual fashion. If K did not occupy the ICU bed, the bed would not move to an under-served area, nor would the unexpended cost of K’s breathing tubes and procedures be converted into mosquito nets for children in malaria-afflicted territories. Values are not generally translatable, any more than their costs are portable.
But the missing cipher in the professionals’ calculation was K’s value to her mother. Someone did experience K’s physiology after all. To waive K’s value on that account was just as degrading as crass service to the beating heart. If the medical professions seek to serve health, and health is function, then the milieu is everything. It was a mistake to consider K’s value on the basis of K’s intrinsic capacity for experience, just as much as it was a mistake to think that the ventilator was saving K herself from or for anything. However mistaken she was about Forms and their efficacy, K’s mother valued K’s beating heart in a consistent way. Harm would come to the mother from K’s heart stopping. It would be the same sort of harm – loss of experience and the possibility of experience – to which the professionals referred in their assessment of K’s lack of value.
All along, the players in the Baby K saga evaluated her with standards that did not apply – that were not truth-apt. It was never the case that Baby K was human or not, alive or not. Her case nicely demonstrates the nature of the harder problem. Our standards – good, evil, human, matter, energy, mine, yours, blue, purple – are not stand-alone things. They are made of their circumstances (our circumstances). Without a doubt, the standards serve us well, since our circumstances are necessarily shared. If the standards refer to the specifics, and the specifics are near enough alike, it’s just good fudging to defer to the standards. It is easy to forget that the standards defer to their instances. And we are motivated to forget, because we value our experience and we value our standards, and we are prone to equate the two.
