Generally speaking, an analysis of animal behavior is not considered scientific unless the animal is assumed, at least tacitly, to be operating according to the same means/end calculations that one would apply to economic transactions. Under this assumption, an expenditure of energy must be directed toward some goal, whether it be obtaining food, securing territory, achieving dominance, or maximizing reproductive success—unless one can absolutely prove that it isn’t, and absolute proof in such matters is, as one might imagine, very hard to come by.
I must emphasize here that it doesn’t really matter what sort of theory of animal motivation a scientist might entertain: what she believes an animal to be thinking, whether she thinks an animal can be said to be “thinking” anything at all. I’m not saying that ethologists actually believe that animals are simply rational calculating machines. I’m simply saying that ethologists have boxed themselves into a world where to be scientific means to offer an explanation of behavior in rational terms—which in turn means describing an animal as if it were a calculating economic actor trying to maximize some sort of self-interest—whatever their theory of animal psychology, or motivation, might be.
That’s why the existence of animal play is considered something of an intellectual scandal. It’s understudied, and those who do study it are seen as mildly eccentric. As with many vaguely threatening, speculative notions, difficult-to-satisfy criteria are introduced for proving animal play exists, and even when it is acknowledged, the research more often than not cannibalizes its own insights by trying to demonstrate that play must have some long-term survival or reproductive function.
Despite all this, those who do look into the matter are invariably forced to the conclusion that play does exist across the animal universe. And exists not just among such notoriously frivolous creatures as monkeys, dolphins, or puppies, but among such unlikely species as frogs, minnows, salamanders, fiddler crabs, and yes, even ants—which not only engage in frivolous activities as individuals, but also have been observed since the nineteenth century to arrange mock-wars, apparently just for the fun of it.
Why do animals play? Well, why shouldn’t they? The real question is: Why does the existence of action carried out for the sheer pleasure of acting, the exertion of powers for the sheer pleasure of exerting them, strike us as mysterious? What does it tell us about ourselves that we instinctively assume that it is?
It’s not just that scientists are reluctant to set out on a path that might lead them to see play—and therefore the seeds of self-consciousness, freedom, and moral life—among animals. Many are finding it increasingly difficult to come up with justifications for ascribing any of these things even to human beings. Once you reduce all living beings to the equivalent of market actors, rational calculating machines trying to propagate their genetic code, you accept that not only the cells that make up our bodies, but whatever beings are our immediate ancestors, lacked anything even remotely like self-consciousness, freedom, or moral life—which makes it hard to understand how or why consciousness (a mind, a soul) could ever have evolved in the first place.
What would happen if we proceeded from the reverse perspective and agreed to treat play not as some peculiar anomaly, but as our starting point, a principle already present not just in lobsters and indeed all living creatures, but also on every level where we find what physicists, chemists, and biologists refer to as “self-organizing systems”?
This is not nearly as crazy as it might sound.
Philosophers of science, faced with the puzzle of how life might emerge from dead matter or how conscious beings might evolve from microbes, have developed two types of explanations.
The first consists of what’s called emergentism. The argument here is that once a certain level of complexity is reached, there is a kind of qualitative leap where completely new sorts of physical laws can “emerge”—ones that are premised on, but cannot be reduced to, what came before. In this way, the laws of chemistry can be said to be emergent from physics: the laws of chemistry presuppose the laws of physics, but can’t simply be reduced to them. In the same way, the laws of biology emerge from chemistry: one obviously needs to understand the chemical components of a fish to understand how it swims, but chemical components will never provide a full explanation. In the same way, the human mind can be said to be emergent from the cells that make it up.
Those who hold the second position, usually called panpsychism or panexperientialism, agree that all this may be true but argue that emergence is not enough. As British philosopher Galen Strawson recently put it, to imagine that one can travel from insensate matter to a being capable of discussing the existence of insensate matter in a mere two jumps is simply to make emergence do too much work. Something has to be there already, on every level of material existence, even that of subatomic particles—something, however minimal and embryonic, that does some of the things we are used to thinking of life (and even mind) as doing—in order for that something to be organized on more and more complex levels to eventually produce self-conscious beings. That “something” might be very minimal indeed: some very rudimentary sense of responsiveness to one’s environment, something like anticipation, something like memory. However rudimentary, it would have to exist for self-organizing systems like atoms or molecules to self-organize in the first place.
Physicists are more playful and less hidebound creatures than, say, biologists—partly, no doubt, because they rarely have to contend with religious fundamentalists challenging the laws of physics. They are the poets of the scientific world. If one is already willing to embrace thirteen-dimensional objects or an endless number of alternative universes, or to casually suggest that 95 percent of the universe is made up of dark matter and energy about whose properties we know nothing, it’s perhaps not too much of a leap to also contemplate the possibility that subatomic particles have “free will” or even experiences. And indeed, the existence of freedom on the subatomic level is currently a heated question of debate.
Is it meaningful to say an electron “chooses” to jump the way it does? Obviously, there’s no way to prove it. The only evidence we could have (that we can’t predict what it’s going to do), we do have. But it’s hardly decisive. Still, if one wants a consistently materialist explanation of the world—that is, if one does not wish to treat the mind as some supernatural entity imposed on the material world, but rather as simply a more complex organization of processes that are already going on, at every level of material reality—then it makes sense that something at least a little like intentionality, something at least a little like experience, something at least a little like freedom, would have to exist on every level of physical reality as well.
The crucial thing to design in a videogame is the moment when nothing happens. Is our player still immersed and enchanted when they release control? When the only verb available is the most important one of all: to be.
