Does Dog Exist? A tail of philosophy, AI, and the pursuit of happiness.

Dog?

In a scan of The Atlantic homepage recently, I came across Are You a Platonist or an Aristotelian? I was especially intrigued by the subtitle: "Your answer may determine how happy you can be." I thought it might be useful given what's happening, both normal (Earth's 23º tilt + orbital position = shorter days) and very much abnormal (US elections).

However not far into the article I was sidetracked from my pursuit of happiness when I learned that "Does Dog exist?" is an eternal question among philosophers, debated at least since 400 BC. Was Plato right? Is there an unchanging ideal that is the true essence of Dog? Or was Aristotle right? Are our diverse too-short-lived dogs all that we have?

Having had canine field assistants most of my career, I tend to feel I'm an expert on such topics. Also, I think philosophers delight in making easy questions difficult, for example "Does Dog exist?". But my actual knowledge of philosophy is minuscule, so I queried DuckDuckGo (my preferred search engine).

At the top of the page, above the results, I was offered the services of DuckAssist—DDG's AI—which "scans the web for relevant content and then uses AI-powered natural language technology to generate a brief answer". I was very curious. I clicked on "Generate" and after just a second or two, DuckAssist replied:

"The question of whether a dog truly exists can be explored through philosophical discussions about particulars and universals. A dog, as a particular animal, is undeniably real and can be seen and touched, while the concept of "dog" as a category represents a set of characteristics that define what it means to be a dog."

That's it?! You would think that after nearly two millennia there would be a better answer. Maybe the problem lies with DuckAssist; after all this is a Beta release. So I continued to the two websites it recommended.

The first—Is a Dog Really a Dog? at Philosophy is Not a Luxury—was similar to DuckAssist's answer but much longer. It may have been the main or only source of content. Not convinced that "philosophy is not a luxury", I went to the second recommended site: I wag, therefore I am in The Guardian.

At this site there was nothing about whether Dog exists. Instead, author Mark Rowland discussed dog philosophy in an excerpt from his book, The Happiness of Dogs. Apparently DuckAssist missed the mark by making a common AI error, specifically "Too Eager to Please". But it was a nice coincidence, as my dog does this too.

Just trying to help!

Emmie is half Basenji and therefore bred to kill small animals. This she does eagerly, even those that never lived. Likewise, an AI is driven by its breeding:

"Generative AI needs to create a response to your query, even if it isn’t capable of giving you one ... If the AI doesn’t have enough actual information in its knowledge base, it fills in gaps with stuff that sounds like it could be correct ..." (more here).

But is this really an error? After all, DuckAssist brought me back to the pursuit of happiness. Maybe it read my mind!

Rowland, a philosopher himself, considers dogs "natural philosophers"—they understand "what is important in [life], and how to live it. Philosophers have done their best to address these questions, with limited success. But dogs answer them effortlessly and decisively. Humans think about these questions, but dogs live them."

So much joy in life!

Our problem is that each of us is two beings—"one who thinks and one who is thought about". It's too much thinking that keeps us from being happy. In contrast, a dog—single being that it is—can enjoy something no matter how minor or familiar, and without asking why, or whether it's worth doing.

This certainly is true of Emmie. All it takes is these five words—"Let's go check the mail"—for her to explode with joy. She spins round and round, her small compact body making tight circles along the path all the way to the end of the fence, where she then barks and races off to get any rabbits hiding under the junipers (she has yet to catch one but no matter).

Rowland asks whether humans can ever experience this kind of joy. I too wonder. He says that because we have two lives—"the life that we live and the life that we think about, scrutinise, evaluate and judge"—we can never love life as a dog does. For one thing, a dog doesn't struggle to find meaning in life, while we too often do.

But there's hope. Both Rowland and I are sure that our dogs can help in our pursuit of happiness. We just have to pay attention.

Stay warm.

Maybe yoga will help (Upside-down Dog pose).

What's your purpose in life? To keep your dog happy, of course!

My role model?

NOTE  

The article about philosophy and happiness is by Arthur C. Brooks, a regular contributor to The Atlantic. He argues that Platonists emphasize what they are, which can interfere with happiness, while Aristotelians have greater potential for happiness because they define themselves mainly as works in progress. But he adds, "Neither being nor becoming is exclusively true or exists to the exclusion of the other." I can't say I was persuaded; maybe I didn't fully understand.

Tree Following: Killer Cottonwood in Utah

On a hot afternoon several weeks ago, I pulled into Hittle Bottom Campground on the Colorado River in southern Utah. After parking in the only site with shade, I opened the windows, put screens in place, inserted $10 in the payment envelope, and started for the pay station. But I was stopped in my tracks by a Killer Tree, right next to our campsite!

The area around it had been cordoned off with orange caution tape, but I checked carefully to make sure we were safe. Indeed everything was fine. We were out of range of falling limbs.

The big cottonwoods that grow along lowland rivers in North America—Populus deltoides and P. fremontii —are infamous for dropping large dead branches. As the Colorado AAA has observed:

No one writes poems about “under the spreading cottonwood tree” because it can actually be dangerous to sit under a cottonwood in high winds due to breaking branches.

The technical term for this is "dieback".

Some cities (Denver for example) ban these cottonwoods in part because of dieback. They grow fast (to six feet per year!) and are relatively short-lived, so falling limbs will be a problem. And they grow roots toward and into reliable water sources such as city water and sewer lines! This is an impressive adaptation for the trees but a problem for us (source).

The Hittle Bottom Campground has no water aside from the river, so managers don't worry about cottonwood roots invading plumbing. But dieback is a problem, hence the caution tape. Of course I wanted photos, so I risked my life so in the absence of imminent danger (the day was calm) I stepped over the tape to commune with the Killer Tree.

The bark was especially photogenic, even with tape.

This is Fremont's Cottonwood, named to honor the famous explorer and surveyor John Charles Fremont. However the honor probably celebrates another of his achievements, one less widely known—botanical discovery! Fremont was not a taxonomic expert but he knew how to collect plants. And collect he did—on the order of two thousand specimens. Among these were at least 165 species new to science, some 40 of which were named in his honor. For more about Fremont's botanizing, see JC Fremont was here.

On the afternoon of March 30, 1846, Fremont and his party "encamped on Deer Creek, another of these beautiful tributaries to the Sacramento [River, in California]. Mr. Lassen, a native of Germany, has established a rancho here ...". They stayed for five days, during which time Fremont collected plants, including a cottonwood. He suspected it might be a new species, as he had noted the previous year when he was in southern Utah (no collection was made or survived).

Fremont's 1846 specimen from "Deer Creek at Lassens" (Gray Herbarium). He collected both male (above) and female (below) flowers, demonstrating knowledge and care in collecting plants.

Typical of field botanists at that time, Fremont relied on experts for identification. He sent many of his collections to the leading American plant taxonomist—Asa Gray at Harvard. Gray often passed along western specimens to his colleague, Sereno Watson, who was more familiar with that flora. It was Watson who named and described Populus fremontii.

Sereno Watson (Wikimedia). A colleague described him as "tall, very erect, [with] good features, a high-bridged nose, and a carefully tended beard of great length and whiteness. Almost to the end of his life he walked with a brisk elastic step suggesting physical energy remarkable for a man of his years."

In his 1875 paper, Watson distinguished P. fremontii from its close relatives "especially by the remarkably developed torus" (now called floral disc). He also noted that young growth tended to be somewhat hairy. In contrast, the similar P. deltoides has smaller floral discs and young growth is not hairy.

A century later, James Eckenwalder, expert on the genus Populus, reached the same conclusions, recognizing the larger floral disc and often hairy young growth as distinguishing features for Fremont's Cottonwood (see also his treatment in Flora of North America).

Addendum, 23 Oct 2024. Posch, BC, et al. (2024) found Populus fremontii to be super efficient at leaf cooling (via transpiration) even when temperatures exceed 48 °C (118º F)! But water must be available. Even a minor disruption in availability will shut down cooling, causing leaves to overheat. See Intensive leaf cooling promotes tree survival during a record heatwave.
