Neuropsychologists Gabriel de la Torre and Manuel García, from the University of Cádiz, in an article recently published in the journal Acta Astronautica, set out to “explain how our own neurophysiology, psychology and consciousness… play a major role in [the] search [for] non-terrestrial civilizations … and how they have been neglected up to this date.” (How the researchers managed to neglect the not irrelevant work of Jacques Vallee (from 1990!) or that of Susan Palmer and myself (from nearly twenty years ago) is itself an interesting case of the phenomenon they are investigating….).
Their research concerns inattention blindness, like that demonstrated by the Invisible Gorilla Experiment of Chabris and Simons. Following their example, de la Torre and García had 137 subjects distinguish artificial structures from natural features in aerial photographs, one of which contained a tiny gorilla. The complement to attention blindness, the mind’s tendency to perceive pattern in chaos (pareidolia), was addressed as well. The implication of their research is that the SETI focus on electromagnetic signals, in either the visible or invisible spectrums, primes it to miss those evidential “gorillas” that would indicate non-terrestrial civilizations. The pair goes on to propose a tripartite classification of such civilizations, all of which, in general, are characterized by their varying degrees of mastery over forms of matter and energy, whether quantum, gravitational, or dark.
What is ironic is that de la Torre and García have fallen prey to the same prejudices that keep SETI researchers and proponents of the Extra-Terrestrial Hypothesis concerning the origin of UFOs from perceiving the intelligent life that swarms around us. As I’ve written elsewhere these prejudices are that intelligent life is intelligent in the way we ourselves conceive ourselves to be, cultural, tool-using creatures capable of mathematical thought and cognizing natural laws that are then exploited technologically, and that such civilizations follow universal paths of linear development toward increasing sophistication, knowledge, and mastery over nature. These prejudices are, arguably, the reification and projection of the history of one culture on earth, namely the one that calls itself the developed world, a culture resulting hardly from a natural, cultural evolution (the pairing of which adjectives should be illuminating enough) but from a highly contingent history that could have as easily followed countless other paths.
In terms of “civilization”, the founder of ethnopoetics, Jerome Rothenberg, makes a pertinent observation in the Pre-face to the first edition of his epochal assemblage Technicians of the Sacred (1967): “Measure everything by the Titan rocket & the transistor radio, & the world is full of primitive peoples. But once change the unit of value to the poem or the dance-event or the dream (all clearly artifactual situations) & it becomes apparent what all these people have been doing all those years with all that time of their hands.” When one considers that the oldest, continuous society on earth is not China but that of the Australian Aborigines, whose oral poetry sings of a ground sloth extinct 60, 000 years, the variability if not relativity of technical ingenuity becomes apparent.
Intelligence, as well, is neither a simple, nor exclusively technical, nor even human attribute. Some human beings are breath-taking coders, but their smarts are outwitted by the ability of a chickadee to remember where it’s stashed its seeds. Indeed, the attempt to imagine nonhuman intelligence, like the one Denise L. Herzing undertakes in her 2013 paper “Profiling nonhuman intelligence: An exercise in developing unbiased tools for describing other ‘types’ of intelligence on earth” expands intelligent life to include dolphins, octopus, insects, and even some bacteria. Even fruit flies can be shown to make decisions.
If we extend our curiosity to sentience, self-awareness, then the standard mirror test shows that Asian elephants, all the great apes, bottlenose dolphins, orca whales, Eurasian magpies, and even ants possess self-consciousness. And as thought-provoking as it is controversial is the contention of plant neurobiologist Stefan Mancuso that plants possess intelligence and sentience, albeit in a radically nonhuman way. Little wonder then that on 7 July 2012, “a prominent international group of cognitive neuroscientists, neuropharmacologists, neurophysiologists, neuroanatomists and computational neuroscientists gathered at The University of Cambridge to reassess the neurobiological substrates of conscious experience and related behaviors in human and non-human animals” drafted and signed The Cambridge Declaration of Consciousness, that, based on four “unequivocal observations”
“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.”
I leave it to interested parties to google “panpsychism”….
An aspect of the tale of Narcissus often forgotten or missed is that Narcissus failed to recognize himself in his own reflection. Like Narcissus, SETI researchers and their critics de la Torre and García and the proponents of the ETH fail to recognize that their speculations concerning intelligence and civilization are merely projections of humankind. Despite Darwin and the libraries of research conducted on nonhuman and even plant sentience and intelligence, the reigning prejudice still seems to be what philosophers would call that “ontotheological” one, that Man is made in God’s own image. Once we disabuse ourselves of this mere speciesism, then we see that SETI is merely (“mirrorly”) a search for ourselves and that this prejudice blinds us to the mind-boggling richness of nonhuman life, sentience, and intelligence already sharing this planet with us, at the same time it perhaps mercifully spares us realizing the heart-breaking suffering we impose on innumerable other forms of life. Perhaps it is precisely because of the latter realization we refuse to recognize a sentience like our own in other living beings and turn our gaze from the earth to the stars at our own and increasingly the biosphere’s peril.
