These are stimulating times for anyone interested in questions of animal consciousness. On what seems like a monthly basis, scientific teams announce the results of new experiments, adding to a preponderance of evidence that we’ve been underestimating animal minds, even those of us who have rated them fairly highly. New animal behaviors and capacities are observed in the wild, often involving tool use—or at least object manipulation—the very kinds of activity that led the distinguished zoologist

Griffin to found the field of cognitive ethology (animal thinking) in 1978: octopuses piling stones in front of their hidey-holes, to name one recent example; or dolphins fitting marine sponges to their beaks in order to dig for food on the seabed; or wasps using small stones to smooth the sand around their egg chambers, concealing them from predators. At the same time neurobiologists have been finding that the physical structures in our own brains most commonly held responsible for consciousness are not as rare in the animal kingdom as had been assumed. Indeed they are common. All of this work and discovery appeared to reach a kind of crescendo several years ago, when an international group of prominent neuroscientists meeting at the University of Cambridge issued “The Cambridge Declaration on Consciousness in Non-Human Animals,” a document stating that “humans are not unique in possessing the neurological substrates that generate consciousness.” It goes further to conclude that numerous documented animal behaviors must be considered “consistent with experienced feeling states.”
Excerpt | The Cambridge Declaration on Consciousness in Non-Human Animals

We declare the following: “The absence of a neocortex does not appear to preclude an organism from experiencing affective states. Convergent evidence indicates that non-human animals have the neuroanatomical, neurochemical, and neurophysiological substrates of conscious states along with the capacity to exhibit intentional behaviors. Consequently, the weight of evidence indicates that humans are not unique in possessing the neurological substrates that generate consciousness. Nonhuman animals, including all mammals and birds, and many other creatures, including octopuses, also possess these neurological substrates.”
That is technical language, but it speaks to a riddle age-old and instinctive. These thoughts begin, for most of us, typically, in childhood, when we are making eye contact with a pet or wild animal. I go back to our first family dog, a preternaturally intelligent-seeming Labrador mix, the kind of dog who herds (image) playing children away from the street at birthday parties, an animal who could sense if you were down and would nuzzle against you for hours, as if actually sharing your pain. I can still hear people, guests and relatives, talking about how smart she was. “Smarter than some people I know!” But when you looked into her eyes—mahogany discs set back in the grizzled black of her face—what was there? I remember the question forming in my mind: can she think? The way my own brain felt to me, the sensation of existing inside a consciousness, was it like that in there?
For most of the history of our species, we seem to have assumed it was. Trying to recapture the thought life of prehistoric peoples is a game wise heads tend to leave alone, but if there’s a consistent motif in the artwork made between four thousand and forty thousand years ago, it’s animal-human hybrids, drawings and carvings and statuettes showing part man or woman and part something else—lion or bird or bear. Animals knew things, possessed their forms of wisdom. They were beings in a world of countless beings. Taking their lives was a meaningful act, to be prayed for beforehand and atoned for afterward, suggesting that beasts were allowed some kind of right. We used our power over them constantly and violently, but stopped short of telling ourselves that creatures of alien biology could not be sentient or that they were incapable of true suffering and pleasure. Needing their bodies, we killed them in spite of those things.
(image) The sheer number and variety of experiments carried out in the twentieth century—and with, if anything, a renewed intensity in the twenty-first—exceeds summary. Reasoning, language, neurology, the science of emotions—every chamber where “consciousness” is thought to hide has been probed. Birds and chimps and dolphins have been made to look at themselves in mirrors—to observe whether, on the basis of what they see, they groom or preen (a measure, if somewhat arbitrary, of self-awareness). Dolphins have been found to grieve. Primates have learned symbolic or sign languages and then been interrogated with them. Their answers show thinking but have proved stubbornly open to interpretation on the issue of “consciousness,” with critics warning, as always, about the dangers of anthropomorphism, animal-rights bias, etc.
Regardless, though, of whether they can talk to us, we’ve learned more and more about the complex ways in which they talk to each other. Entomologists mastered the dance code of the bees and spoke it to them, using a tiny bee-puppet. (For the bees it may have been as if the puppet had a strange accent). In more recent years the numerous calls that elephants make to one another across 150-mile distances have been recorded and decoded. Evidently the individual animals can tell each other apart. So there are conversations of some kind taking place. Zoologists have observed elephants having, for instance, a “departure conversation” at a watering hole, rustling their great heads together in a “rumbling,” communicating about the decision to leave; the water is no good here, we should move on. Who knows what they’re saying. Ludwig Wittgenstein said that if a lion could talk, we wouldn’t understand it. It may, as it turns out, be truer to say that we wouldn’t understand it very well.
If we put aside the self-awareness standard—and really, how arbitrary and arrogant is that, to take the attribute of consciousness we happen to possess over all creatures and set it atop the hierarchy, proclaiming it the very definition of consciousness (Georg Christoph Lichtenberg wrote something wise in his notebooks, to the effect of: only a man can draw a self-portrait, but only a man wants to)—it becomes possible to say at least the following: the overwhelming tendency of all this scientific work, of its results, has been toward more consciousness. More species having it, and species having more of it than assumed. This was made boldly clear when the “Cambridge Declaration on Consciousness” pointed out that those “neurological substrates” necessary for consciousness (whatever “consciousness” is) belong to “all mammals and birds, and many other creatures, including octopuses.” The animal kingdom is symphonic with mental activity, and of its millions of wavelengths, we’re born able to understand the minutest sliver. The least we can do is have a proper respect for our ignorance.
The philosopher Thomas Nagel wrote an essay in 1974 titled, “What Is It Like To Be a Bat?”, in which he put forward perhaps the least overweening, most useful definition of “animal consciousness” ever written, one that channels Spinoza’s phrase about “that nature belonging to him wherein he has his being.” Animal consciousness occurs, Nagel wrote, when “there is something that it is to be that organism—something it is like for the organism.” The strangeness of his syntax carries the genuine texture of the problem. We’ll probably never be able to step far enough outside of our species-reality to say much about what is going on with them, beyond saying how like or unlike us they are. Many things are conscious on the earth, and we are one, and our consciousness feels like this; one of the things it causes us to do is doubt the existence of the consciousness of the other millions of species. But it also allows us to imagine a time when we might stop doing that.

An important article, thank you. Nature and animals help humans to realize their consciousness. It’s much more challenging to see oneself as a living breathing being by looking into a computer screen or handheld device. Take for example, therapy dogs helping individuals see beyond their illness and relate to another living thing thereby increasing the healing process.
