Reading, and Sensing an Immense World: It Takes a Universe

A wonderful friend and former colleague recommended a book to me that I found fascinating. It’s called An Immense World: How Animal Senses Reveal the Hidden Realms Around Us, by Ed Yong. It speaks to so many issues and concerns of our world today.

 

We both live the truth, and an illusion. The world we perceive can be so clear, immediate, and vital to us. Yet it sits imbedded in innumerable other worlds, universes, though we don’t and can’t perceive almost any of them. We mistake what we see for all that is there. What we perceive is not the world but one our human brain and body have evolved to perceive.

 

For example, Yong points out that we humans “cannot sense the faint electric fields that sharks and platypuses can…[nor] the magnetic fields that robins and sea turtles detect.” Our ears can’t hear the ultrasonic calls of hummingbirds or the infrasonic speech of elephants and whales. We can’t perceive the infrared radiation that is the heart of what snakes detect or the ultraviolet light birds and bees sense every moment.

 

Each species has what Yong, borrowing from Baltic-German zoologist Jakob von Uexkull, called an umwelt or perceptual world. A tick does not perceive a tree, green leaves, blue skies. It doesn’t ignore them. It simply is incapable of sensing or knowing them; they are outside its umwelt. Likewise, we can’t sense the tick’s world.

 

Too often we ignore, or are ignorant of these co-existing realties, and we harm other species by imposing our perceptual system bias on them. For example, our submarines use underwater noises that confuse whales and drown out their calls. The glass panes in our homes appear as bodies of water to a bat’s sonar. We hurt our cats and dogs by interfering in their use of their primary sense activity, sniffing, and unknowingly impose our human visual bias on them.

 

If we can’t understand what the other worlds are like to live in, Yong points out maybe we can use our reason and imagination to honor and recognize them. For example, we can imaginatively enter the world of a dog, or even more so, an elephant. Scents, unlike light, do not move in straight lines. They go around corners, up and down, swirl, and twist in all directions. Humans have fine noses. But a dog not only has more sense receptors, a larger olfactory bulb and scent-brain than we do, but a more complicated nasal structure.

 

When we humans exhale, we purge odors from our nose. But each nostril of a dog is divided in two so it can exhale carbon dioxide while inhaling more aromas. This is one reason they can detect low blood sugar levels or tumors in humans or discern a single fingerprint on a microscopic slide even after it was outdoors for a week. They can smell in the air an oncoming storm.

 

For dogs, everything around them includes the scent not only of what’s here, now, but the past and future. And smell has the most direct link to the brain of any sense. And since that link goes right to the brain’s emotional center, I imagine their world is dominated by emotions. Some might doubt the rich emotional lives of many animals but this science argues otherwise….

That First Taste of Consciousness: The Family of Awareness Is Infinite

Just imagine the moment when the first human being, hominid, or whomever first became conscious. Not just when a human felt for the first time their feet on the earth; but the first time any hominid was aware they were aware of where they placed their feet and where they were going. First became aware of the beauty in the scent from a flower, or in a sunrise, or first became aware of a memory of a bad morning.

 

One of my closest friends was talking about this with me on a recent Zoom call. What a powerful moment to consider. Was there ever such a moment? Or has consciousness always, somehow, been part of nature?

 

And this image can tease us on so many levels. Think of a baby. When is it first aware of itself? In the womb? At birth? When someone takes away its toy, a parent calls its name, or leaves them alone? Or it cries when another infant or its mother cries?

 

Anthropologists and others speculate humans had an increase in consciousness somewhere between 60,000 and 30,000 years ago, when the first art caves were created, or maybe when the first languages were developed. Or maybe before that? Art and written language are likely indicators of conscious awareness.

 

Human consciousness is doubly aware. Our species name is, after all, homo sapiens sapiens, humans twice wise. We know (somewhere inside us) by knowing we know. Conscious means con, or with, scio, to know, or know with. I thought about this in a recent blog. This allows us to reflect on our actions, thoughts, and feelings and learn from the subtlest levels of all of them.

It allows us, when we hold hands with someone we care about, to not only feel their hand and ours but know we feel it.

 

This double awareness can give us the ability to abstract and imagine, to plan or time travel, or substitute an idea for a perception. We can use words to symbolize most anything, including a self, or evoke something in us, to dream, to craft, and to understand reality.

 

Words enable us to leap into a story, one of our own making, or one we adopt from someone else. We prepare ourselves for a future event by telling a story of it. We can name a type of feeling as worrying, dreadful, or lovely. Or talk about something instead of experiencing it. We can distance ourselves from something or stick ourselves to it.

 

Thus, our double awareness can confuse us. It can provide our greatest gifts as well as the source for our greatest suffering. Language and the ability to distance ourselves mentally and emotionally from aspects of the world can create a false sense of separation between the one who knows and what is known. By telling ourselves stories we can create anxiety as well as excitement over what might never be. Since words are abstractions masquerading as objects and other beings, they can deceive us. They create illusions as well as revelations. Because they can help us, they can hurt us….
