Wisdom for the exquisite Existential Comics (“A philosophy comic about the inevitable anguish of living a brief life in an absurd world. Also jokes.”)…
Frege was an early philosopher of language, who formulated a theory of semantics that largely had to do with how we form truth propositions about the world. His theories were enormously influential for people like Russel, Carnap, and even Wittgenstein early in his career. They all recognized that the languages we use are ambiguous, so making exact determinations was always difficult. Most of them were logicians and mathematicians, and wanted to render ordinary language as exact and precise as mathematical language, so we could go about doing empirical science with perfect clarity. Russell, Carnap, and others even vowed to create an exact scientific language (narrator: “they didn’t create an exact scientific language”).
Later on, Wittgenstein and other philosophers such as J.L. Austin came to believe that a fundamental mistake was made about the nature of language itself. Language, they thought, doesn’t pick out truth propositions about the world at all. Speech acts were fundamentally no different than other actions, and were merely used in social situations to bring about certain effects. For example, in asking for a sandwich to be passed across the table, we do not pick out a certain set of facts about the world, we only utter the words with the expectations that it will cause certain behavior in others. Learning what is and isn’t a sandwich is more like learning the rules of a game than making declarations about what exists in the world, so for Wittgenstein, what is or isn’t a sandwich depends only on the success or failure of the word “sandwich” in a social context, regardless of what actual physical properties a sandwich has in common with, say, a hotdog.

As we add mayonnaise, we might send thoughtful birthday greetings to Norbert Wiener; he was born on this date in 1894. A computer scientist, mathematician, and philosopher, Wiener is considered the originator of cybernetics, the science of communication as it relates to living things and machines– a field that has had implications for implications for a wide variety of fields, including engineering, systems control, computer science, biology, neuroscience, and philosophy. (Wiener credited Leibniz as the “patron saint of cybernetics.)
His work heavily influenced computer pioneer John von Neumann, information theorist Claude Shannon, anthropologists Margaret Mead and Gregory Bateson, and many others. Wiener was one of the first to theorize that all intelligent behavior was the result of feedback mechanisms and could possibly be simulated by machines– an important early step towards the development of modern artificial intelligence.

Learning from the past: as John Thornhill explains in his consideration of Jason Roberts‘ Every Living Thing, the rivalry between Buffon and Linnaeus has lessons about disrupters and exploitation…
The aristocratic French polymath Georges-Louis Leclerc, Comte de Buffon chose a good year to die: 1788. Reflecting his status as a star of the Enlightenment and author of 35 popular volumes on natural history, Buffon’s funeral carriage drawn by 14 horses was watched by an estimated 20,000 mourners as it processed through Paris. A grateful Louis XVI had earlier erected a statue of a heroic Buffon in the Jardin du Roi, over which the naturalist had masterfully presided. “All nature bows to his genius,” the inscription read.
The next year the French Revolution erupted. As a symbol of the ancien regime, Buffon was denounced as an enemy of progress, his estates in Burgundy seized, and his son, known as the Buffonet, guillotined. In further insult to his memory, zealous revolutionaries marched through the king’s gardens (nowadays known as the Jardin des Plantes) with a bust of Buffon’s great rival, Carl Linnaeus. They hailed the Swedish scientific revolutionary as a true man of the people.
The intense intellectual rivalry between Buffon and Linnaeus, which still resonates today, is fascinatingly told by the author Jason Roberts in his book Every Living Thing, my holiday reading while staying near Buffon’s birthplace in Burgundy. Natural history, like all history, might be written by the victors, as Roberts argues. And for a long time, Linnaeus’s highly influential, but flawed, views held sway. But the book makes a sympathetic case for the further rehabilitation of the much-maligned Buffon.
The two men were, as Roberts writes, exact contemporaries and polar opposites. While Linnaeus obsessed about classifying all biological species into neat categories with fixed attributes and Latin names (Homo sapiens, for example), Buffon emphasised the vast diversity and constantly changing nature of every living thing.
In Roberts’s telling, Linnaeus emerges as a brilliant but ruthless dogmatist, who ignored inconvenient facts that did not fit his theories and gave birth to racial pseudoscience. But it was Buffon’s painstaking investigations and acceptance of complexity that helped inspire the evolutionary theories of Charles Darwin, who later acknowledged that the Frenchman’s ideas were “laughably like mine”.
In two aspects, at least, this 18th-century scientific clash rhymes with our times. The first is to show how intellectual knowledge can often be a source of financial gain. The discovery of crops and commodities in other parts of the world and the development of new methods of cultivation had a huge impact on the economy in that era. “All that is useful to man originates from these natural objects,” Linnaeus wrote. “In one word, it is the foundation of every industry.”
Great wealth was generated from trade in sugar, potatoes, coffee, tea and cochineal while Linnaeus himself explored ways of cultivating pineapples, strawberries and freshwater pearls.
“In many ways, the discipline of natural history in the 18th century was roughly analogous to technology today: a means of disrupting old markets, creating new ones, and generating fortunes in the process,” Roberts writes. As a former software engineer at Apple and a West Coast resident, Roberts knows the tech industry.
Then as now, the addition of fresh inputs into the economy — whether natural commodities back then or digital data today — can lead to astonishing progress, benefiting millions. But it can also lead to exploitation. As Roberts tells me in a telephone interview, it was the scaling up of the sugar industry in the West Indies that led to the slave trade. “Sometimes we think we are inventing the future when we are retrofitting the past,” he says.
The second resonance with today is the danger of believing we know more than we do. Roberts compares Buffon’s state of “curious unknowing” to the concept of “negative capability” described by the English poet John Keats. In a letter written in 1817, Keats argued that we should resist the temptation to explain away things we do not properly understand and accept “uncertainties, mysteries, doubts, without any irritable reaching after fact and reason.”
Armed today with instant access to information and smart machines, the temptation is to ascribe a rational order to everything, as Linnaeus did. But scientific progress depends on a humble acceptance of relative ignorance and a relentless study of the fabric of reality. The spooky nature of quantum mechanics would have blown Linnaeus’s mind. If Buffon still teaches us anything, it is to study the peculiarity of things as they are, not as we might wish them to be…

As we embrace the exceptions, we might send carefully-coded birthday greetings to John McCarthy; he was born on this date in 1927. An eminent computer and cognitive scientist– he was awarded both the Turning Prize and the National Medal of Science– McCarthy coined the phrase “artificial Intelligence” to describe the field of which he was a founder.
It was McCarthy’s 1979 article, “Ascribing Mental Qualities to Machines” (in which he wrote, “Machines as simple as thermostats can be said to have beliefs, and having beliefs seems to be a characteristic of most machines capable of problem solving performance”) that provoked John Searle‘s 1980 disagreement in the form of his famous Chinese Room Argument… provoking a broad debate that continues to this day.

As we live and learn, we might spare a thought for Grace Brewster Murray Hopper; she died on this date in 1992. A seminal computer scientist and Rear Admiral in the U.S. Navy, “Amazing Grace” (as she was known to many in her field) was one of the first programmers of the Harvard Mark I computer (in 1944), invented the first compiler for a computer programming language, and was one of the leaders in popularizing the concept of machine-independent programming languages– which led to the development of COBOL, one of the first high-level programming languages.
Hopper also (inadvertently) contributed one of the most ubiquitous metaphors in computer science: she found and documented the first computer “bug” (in 1947).
She has both a ship (the guided-missile destroyer USS Hopper) and a super-computer (the Cray XE6 “Hopper” at NERSC) named in her honor.

“We are as gods and might as well get good at it”*…
In 1968, Stewart Brand and small group of colleagues published the first Whole Earth Catalog, then followed it over the years with a series of updates, spin-offs, and sequels. An at-the-time unprecedented marriage of counterculture magazine and product catalog, it (and its successors) have been enormously influential. Now, as Long Now‘s Jacob Kupperman reports, the entire run of Whole Earth publications is freely available online…
When the Whole Earth Catalog arrived in the Fall of 01968, it came bearing a simple, epochal label: “Access to Tools.” As its editor and Long Now Co-founder Stewart Brand wrote in the introduction to that first edition, the goal was for the Catalog to serve as an “evaluation and access device” for tools that empowered its readers “to conduct his own education, find his own inspiration, shape his own environment, and share his adventure with whoever is interested.”
The key word in all of that idealistic declaration of purpose was “access.” The Whole Earth Catalog did not intend to directly grant its readers this knowledge, wisdom, and mastery, but to provide a kaleidoscopic array of gateways from which they could attempt to find it themselves.
Yet for years, access to the Whole Earth Catalog itself has been difficult. 55 years on from the first publication of the Catalog, it mostly lives on in the interstices — as a symbol of a vibrant countercultural history and an inspiration for writers, designers, and technologists, but less so as an actual set of catalogs that you can read. The Catalog is not lost media per se — copies can be found in libraries, archives, and personal collections across the world — but accessing its trove of information is no longer as easy as it was in its heyday.
That is, until now.
on the 55th anniversary of the publication of the original Whole Earth Catalog, Gray Area and the Internet Archive have made the Catalog freely available online via the Whole Earth Index, a website bringing together more than 130 Whole Earth Catalog-related publications, ranging from some of the earliest Catalogs published in the late 01960s and early 01970s to 02002 issues of Whole Earth Magazine.
Within the site’s grid of publications rests a cornucopia of writing and curation, from in-depth looks at space colonies to ecological analyses of the insurance industry to reporting on the state of the global teenager at the turn of the 01990s. The Whole Earth Index is a work of love, a noncommercial enterprise designed, as project lead and Gray Area Executive Director Barry Threw told Long Now Ideas, to “allow us to reflect on how we got to where we are and regain some of that connection to the countercultural world” of the Bay Area of the 01960s and 01970s.
…
For the people who helped make the Whole Earth Catalog and its descendants, the Whole Earth Index is in many ways a dream come true. Long Now Board Member Kevin Kelly, who wrote for, edited, and led the CoEvolution Quarterly, the Whole Earth Review, and later editions of the Whole Earth Catalog, told us that he found “the interface to this historic collection to be as good, maybe even better, as reading the original paper artifacts,” adding that he’d “been giddy with delight in how satisfying this archive is.” The project’s model of “instant access from your home, for free!”, Kelly noted, was something that the team behind the Whole Earth Catalog could only dream of when they began their work.
The open-ended design of the Whole Earth Index is intended as a sort of provocation towards future works — a message and invitation in the spirit of the original catalog’s epochal claim that “we are as gods and might as well get good at it.” The tens of thousands of scanned pages will live on the servers of the Internet Archive — as good a place as any to try and stave off a Digital Dark Age — but the ideas of the Whole Earth Catalog and its heirs will always live among those of us who read it and access its tools. What will you do with them?
The Whole Earth Catalog and its descendants are newly available online through the Whole Earth Index: “The Lasting Whole Earth Catalog,” from @Jacobkupp and @longnow.

As we treasure tools, we might spare a thought for a man whose work kicked in about the same time as the Whole Earth Catalog– and intersected with it in myriad ways (e.g., The WELL), Jon Postel; he died on this date in 1998. A computer scientist, he played a pivotal role in creating and administering the Internet. As a graduate student in the late 1960s, he was instrumental in developing ARPANET, the forerunner of the internet. He is known principally for being the Editor of the Request for Comment (RFC) document series from which internet standards emerged, for Simple Mail Transfer Protocol (SMTP), and for founding and administering the Internet Assigned Numbers Authority (IANA) until his death.
During his lifetime he was referred to as the “god of the Internet” for his comprehensive influence; Postel himself noted that this “compliment” came with a barb, the suggestion that he should be replaced by a “professional,” and responded with typical self-effacing matter-of-factness: “Of course, there isn’t any ‘God of the Internet.’ The Internet works because a lot of people cooperate to do things together.”
“Many of the things you can count, don’t count. Many of the things you can’t count, really count”*…
Still, we count… and have, as Keith Houston explains, for much, if not most of human history…
Figuring out when humans began to count systematically, with purpose, is not easy. Our first real clues are a handful of curious, carved bones dating from the final few millennia of the three-million-year expanse of the Old Stone Age, or Paleolithic era. Those bones are humanity’s first pocket calculators: For the prehistoric humans who carved them, they were mathematical notebooks and counting aids rolled into one. For the anthropologists who unearthed them thousands of years later, they were proof that our ability to count had manifested itself no later than 40,000 years ago.
…
Counting, fundamentally, is the act of assigning distinct labels to each member of a group of similar things to convey either the size of that group or the position of individual items within it. The first type of counting yields cardinal numbers such as “one,” “two,” and “three”; the second gives ordinals such as “first,” “second,” and “third.”
At first, our hominid ancestors probably did not count very high. Many body parts present themselves in pairs—arms, hands, eyes, ears, and so on—thereby leading to an innate familiarity with the concept of a pair and, by extension, the numbers 1 and 2. But when those hominids regarded the wider world, they did not yet find a need to count much higher. One wolf is manageable; two wolves are a challenge; any more than that and time spent counting wolves is better spent making oneself scarce. The result is that the very smallest whole numbers have a special place in human culture, and especially in language. English, for instance, has a host of specialized terms centered around twoness: a brace of pheasants; a team of horses; a yoke of oxen; a pair of, well, anything. An ancient Greek could employ specific plurals to distinguish between groups of one, two, and many friends (ho philos, to philo, and hoi philoi). In Latin, the numbers 1 to 4 get special treatment, much as “one” and “two” correspond to “first” and “second,” while “three” and “four” correspond directly with “third” and “fourth.” The Romans extended that special treatment into their day-to-day lives: after their first four sons, a Roman family would typically name the rest by number (Quintus, Sextus, Septimus, and so forth), and only the first four months of the early Roman calendar had proper names. Even tally marks, the age-old “five-barred gate” used to score card games or track rounds of drinks, speaks of a deep-seated need to keep things simple.
Counting in the prehistoric world would have been intimately bound to the actual, not the abstract. Some languages still bear traces of this: a speaker of Fijian may say doko to mean “one hundred mulberry bushes,” but also koro to mean “one hundred coconuts.” Germans will talk about a Faden, meaning a length of thread about the same width as an adult’s outstretched arms. The Japanese count different kinds of things in different ways: there are separate sequences of cardinal numbers for books; for other bundles of paper such as magazines and newspapers; for cars, appliances, bicycles, and similar machines; for animals and demons; for long, thin objects such as pencils or rivers; for small, round objects; for people; and more.
Gradually, as our day-to-day lives took on more structure and sophistication, so, too, did our ability to count. When farming a herd of livestock, for example, keeping track of the number of one’s sheep or goats was of paramount importance, and as humans divided themselves more rigidly into groups of friends and foes, those who could count allies and enemies had an advantage over those who could not. Number words graduated from being labels for physical objects into abstract concepts that floated around in the mental ether until they were assigned to actual things.
Even so, we still have no real idea how early humans started to count in the first place. Did they gesture? Speak? Gather pebbles in the correct amount? To form an educated guess, anthropologists have turned to those tribes and peoples isolated from the greater body of humanity, whether by accident of geography or deliberate seclusion. The conclusion they reached is simple. We learned to count with our fingers…

As we tally, we might send carefully calculated birthday greetings to Stephen Wolfram; he was born on this date in 1959. A computer scientist, mathematician, physicist, and businessman, he has made contributions to all of these fields. But he is probably best known for his creation of the software system Mathematica (a kind of “idea processor” that allows scientists and technologists to work fluidly in equations, code, and text), which is linked to WolframAlpha (an online answer engine that provides additional data, some of which is kept updated in real time).
