Epistemology is cool? What? I’m beginning to believe that many of today’s most interesting problems boil down to epistemology. In our age, we have an epistemological problem that the ancients never dreamt of. To wit, we have discovered that there is really a very, very great amount of things to know. Indeed, there are far more things to know than one puny mind, as we now understand the term, can possibly comprehend in a lifetime.
Simply put, the old epistemological questions were things like “What is knowledge?” or “How do we get to know things?” Now, the question is “How can we get every individual member of our species to know all of the things that he needs to that, collectively, we already know?” More briefly, the old question was “How do we get to know things?” The new question is “How do we get other people to know things?”
It was not always so. With the help of one or two devoted pupils, Aristotle compassed nearly all of the scientific knowledge of his age, and made the greatest of contributions in most other fields too. Aristotle, showed that, in principle at least, the acquisition of complete knowledge by an individual was possible in his time. Even much more recently, it was possible for an educated man to be familiar with all of the most important cultural touchstones of human history; such familiarity made the writings of the nineteenth and twentieth centuries possible.
Today, this is no longer true. I have worked out in some detail (and a long time ago) how the proliferation of knowledge – or at least information – has created a problem in the arts, and particularly literature. I have also discussed, in gloss, how the highly developed nature of scientific knowledge has, in a way, limited mankind’s ability to understand the grave existential threats facing it today. Now I wish to discuss one of the most irritating consequences of our epistemological problem, the persistence of vitalism.
Vitalism is the belief that some separate principle, or essence, occupies living things and makes them distinct from “inanimate” (literally, soulless) matter. A common vitalist proposition is something like, “You can’t create life in the laboratory, because there’s some constituent of life outside the realm of matter that you don’t know about.” Most vitalists are actually mystics: they not only believe that there’s some principle of life that we don’t know about, they also believe we can’t know it, that the scientific method will never understand this mysterious, non-material vital principle.
Put this way, it’s obvious that vitalism is not really a much more dignified belief than the belief in ghosts or ESP. After all, if there’s one aspect of our daily lives that can’t be understood or measured, why not others? If I have a mystic principle animating me that I can’t detect or know anything about, why couldn’t that mystic principle exist outside of the body? Since this mystic, non-material principle seems to be able to influence matter (for instance, by giving me life), why shouldn’t ghosts be able to talk or do whatever else it is that ghosts do?
Of course, most religious types are vitalists too. The vital principle for a religious type is the “soul”, which, when they speak of it, is an entirely separate form and mode of existence from the body, something ethereal and mystical, but somehow capturing all of an individual’s individuality.
Most pre-modern philosophers were also vitalists. The belief in the animating principle spawned Descartes’s mind-body duality, the inane ramblings of Aquinas, and even the more tripped-out theories of the Greek philosophers.
Now, let us imagine our philosopher, our modern philosopher. He has a complete understanding of science, and can imagine, in broad outline, how he could construct a bacterium, or even a simple sponge. It’s not possible yet, of course, because in a way, the smallest microbe poses the same challenge as a great mountain: we know what the mountain, or the bacterium, is made of, but we lack the extraordinary resources that would be required to create one out of nothing. Still, the philosopher knows of what a microbe or a sponge is made, and he mostly understands humans; he’s optimistic that in a hundred years he’ll know everything. Having this knowledge enables the philosopher to completely escape the abyss of vitalism, and in so doing, keep a cautious distance from religion, ancient metaphysics, belief in ghosts, and any number of other intellectual crosses that humanity continues to bear.
Now, the epistemological problem arises: how is he to communicate this knowledge to others? The philosopher acquired his knowledge of the way the world works by decades of painstaking study. It did not take decades because he learned inefficiently, or learned the wrong things; it tooks decades because there was so much to know. In short, the philosopher can only communicate his secret with others by passing on his knowledge, in toto, to them. For anyone to escape the trap of vitalism, decades of study are necessary. Ironically, then, the philosopher, who believes that knowledge is communicable, that the universe is comprehensible, that laws govern the natural world, and that we can discover and use these laws, arrives at the same problem as the mystic, who believes the opposite of all of these things: the philosopher has knowledge, but its transmission is impractical – though not, as with the mystic, impossible.
There is another way. The philosopher could resort to what would now be termed the “technocratic” solution. He could appeal to the unknowing people to trust that his years of study have produced for him intransmissible knowledge, but knowledge that would give him the power to solve problems and help the people. If the appeal is not taken, the same solution applies, through a longer route: build a culture of awe and respect. Over enough generations, the philosopher and his heirs could instill in the people the idea the fervent belief that the philosopher holds superior knowledge. He would, of course, hold such knowledge, though the years of study required to attain it make it hard to prove to the people that he does in fact have the knowledge. That is why the priest, I mean the philosopher, would have to instill belief and trust in the people, as opposed to convincing them on merit.
And therein lies the problem: the philosopher, to receive his power, must appeal to the same devices as the priest. Technocracy ruled our society for millenia before the advent of scientific knowledge; that technocracy was called the priesthood. The priests could not prove to the people that they held superior knowledge, but they said that they did, and they sometimes resorted to tricks to convince people. The philosopher would be left to the same devices, the same claims, and the same arguments that the priest used for thousands of years. To borrow from Arthur C. Clarke (here), the people must view the sufficiently advanced knowledge of the philosopher in the same way they view the magical claims of the priest.
And so, perhaps there is no hope for humanity: the scientists are left to argue with the priests on grounds that, in the eyes of the people, are totally equal. The only difficulty is that the scientists cannot choose their ground, their position on issues; it is determined for them by their very real knowledge. The priests, on the other hand, are free to have “revealed” to them whatever positions the people seem to favor.
Could the scientists outline the argument I have given here, and appeal to the very fact that no one would take their position if not impelled to it by real knowledge? For example, could we appeal to people to believe in global warming because why on Earth would a scientist choose to take the position that we have to adopt a poorer, simpler lifestyle? (There are, actually, many reasons, which I hope to someday discuss.) I think not; such an argument is weak because it rests on no actual information, and can be used as a defense for anyone arguing for an apparently unpopular position.
We can make heroic efforts (such as the one here), but ultimately, we must tackle our epistemological problem before we can solve any of humanity’s other problems.
