Carrion Luggage  Native to the Americas, the turkey vulture (Cathartes aura) travels widely in search of sustenance. While usually foraging alone, it relies on other individuals of its species for companionship and mutual protection. Sometimes misunderstood, sometimes feared, sometimes shunned, it nevertheless performs an important role in the ecosystem. This scavenger bird is a marvel of efficiency. Rather than expend energy flapping its wings, it instead locates uplifting columns of air, and spirals within them in order to glide to greater heights. This behavior has been mistaken for opportunism, interpreted as if it is circling doomed terrestrial animals destined to be its next meal. In truth, the vulture takes advantage of these thermals to gain the altitude needed glide longer distances, flying not out of necessity, but for the joy of it. It also avoids the exertion necessary to capture live prey, preferring instead to feast upon that which is already dead. In this behavior, it resembles many humans. It is not what most of us would consider to be a pretty bird. While its habits are often off-putting, or even disgusting, to members of more fastidious species, the turkey vulture helps to keep the environment from being clogged with detritus. Hence its Latin binomial, which translates to English as "golden purifier." I rarely know where the winds will take me next, or what I might find there. The journey is the destination. |
| I'm not overly familiar with the source of the article I'm featuring today. It's from Open Culture, which bills itself as having "the best free cultural & educational media," and already I distrust it because if you're really the best, you don't need to self-promote as such. But we're going to look at this article anyway. I'd heard this assertion before, but I don't think I've ever blogged about it. The article, incidentally, contains a video with a similar title. I didn't watch it. I don't know if it covers the same material as the writing. I prefer writing over videos. In an old Zen stoÂry, two monks argue over whether a flag is wavÂing or whether itâs the wind that waves. Their teacher strikes them both dumb, sayÂing, âIt is your mind that moves.â That reminds me of how an optimist and a pessimist argue over whether a glass is half-full or half-empty, when, clearly, the glass is twice as big as it needs to be. Such obserÂvaÂtions bring us to anothÂer koan-like quesÂtion: if a lanÂguage lacks a word for someÂthing like the colÂor blue, can the thing be said to exist in the speakerâs mind? It's a fair question, I'll admit, but it seems to me that lots of things exist that we don't have words for. We can disÂpense with the idea that thereâs a colÂor blue âout thereâ in the world. ColÂor is a colÂlabÂoÂraÂtion between light, the eye, the optic nerve, and the visuÂal corÂtex. And yet, claims Maria Michela SasÂsi, proÂfesÂsor of ancient phiÂlosÂoÂphy at Pisa UniÂverÂsiÂty, âevery culÂture has its own way of namÂing and catÂeÂgoÂrizÂing colours.â Can we really dispense with that idea, though? Just as sound is a pressure wave in a medium such as air, water, or something solid, regardless of whether there is an ear around to hear it (so much for the "tree falls in the forest" Zen koan), color is a particular wavelength on the electromagnetic spectrum. I'd argue that insofar as color exists at all, being not a "thing" but a property of a thing, that wavelength that we agree on as "blue" exists, too. How we perceive that color is, to me, a separate issue. The most famous examÂple comes from the ancient Greeks. Since the 18th cenÂtuÂry, scholÂars have pointÂed out that in the thouÂsands of words in the IliÂad and Odyssey, Homer nevÂer once describes anyÂthing â sea, sky, you name it â as blue. I'd heard that, of course, but I still have questions, like: How do we know they didn't use the word for blue if they didn't have a word for blue? And, more importantly: Why are we trusting the color descriptions of a blind poet? It was once thought culÂturÂal colÂor difÂferÂences had to do with stages of evoÂluÂtionÂary develÂopÂment â that more âprimÂiÂtiveâ peoÂples had a less develÂoped bioÂlogÂiÂcal visuÂal sense. Yeah, evolution doesn't really work like that. No matter how primitive the culture seems to our technological senses, people are generally the same, genetically speaking, all over. âIf you think about it,â writes BusiÂness Insiderâs Kevin Loria, âblue doesnât appear much in nature â there arenât blue aniÂmals, blue eyes are rare, and blue flowÂers are mostÂly human creÂations.â Well, yeah, but unless you live in London or Seattle, there's this big thing-that-isn't-a-thing called the daytime sky, which we describe as blue. It's pretty hard to miss unless you live in a cave, which even cavepeople didn't do all the time. The colÂor blue took hold in modÂern times with the develÂopÂment of subÂstances that could act as blue pigÂment, like PrussÂian Blue, inventÂed in Berlin, manÂuÂfacÂtured in ChiÂna and exportÂed to Japan in the 19th cenÂtuÂry. I did a blog entry a while back on that particular pigment; as I recall, it featured in Japanese ("The Wave") and European ("Starry Night") art. But I have my doubts about that being the origin of our shared perception of the color blue. Newton did a lot of study of the color spectrum, breaking up sunlight using a prism like the proto-Dark Side of the Moon cover art, and he included "blue" as a color. I should note, however, that Newton seems to have chosen a seven-color scheme (the actual spectrum covers a lot more than seven shades) because of the mystical association with the number seven: days of the week, visible heavenly bodies that move (sun, moon, and five planets). One modÂern researcher, Jules DavidÂoff, found this to be true in experÂiÂments with a NamibÂian peoÂple whose lanÂguage makes no disÂtincÂtion between blue and green (but names many finÂer shades of green than EngÂlish does). âDavidÂoff says that withÂout a word for a colour,â Loria writes, âwithÂout a way of idenÂtiÂfyÂing it as difÂferÂent, itâs much hardÂer for us to notice whatâs unique about it.â I kind of agree with that, though. There's the old story about how the Inuit have many different words for snow; it's probably false (not least because there are several languages and dialects involved), but it does speak to the larger truth that we name the things we find to be important in our lives. It's an interesting line of inquiry, though. When I was a kid, I remember making an offhand comment to a friend like, "How do I know that the colors I see are the same as the colors you see? Like, we can both agree that this grass is green, but if I could see through your eyes, would I see the same color as I do now?" Those weren't my exact words, which I don't remember, but whatever I said, he understood what I was getting at. Much later, after the internet became a thing, someone echoed my childhood Zen koan and got a bunch of mind-blown reactions. As far as I know, we can't know the answer to that, not yet. Perhaps someday. |
