If a Philosopher Falls in the Forest …

I thought that I might pursue a doctorate here at the University of Texas because the school will pay for up to 5 credit hours per semester for an employee. The plan died aborning. I sent a letter to the philosophy department and they never answered. While I was waiting, I checked out some books from the library to read over Christmas. Among them were two from the department chair, David Sosa, and an anthology on epistemology by a group of Objectivists. I cannot see myself engaged in such meaningless discussions based on unstated, arbitrary assertions. I actually think well of philosophy and invest time in it and if this is the best that they can do, then I confess to hubris here: It is not that I know more than they do but that I think more clearly.

The Mantis Shrimp sees things that you do not.
It is the same universe for all of us.

When I say “red” and you say “red” are we talking about the same thing? People who are color blind adapt to the world around them. It is only by the application of a special visual test—given to aircraft pilots, medical doctors, and others—that we can establish that a person is color blind. These philosophers seem to be disengaged from the experiential world. Their limiting cases are people with eyeglasses. And they gloss over the problem of what it means for tree to appear “fuzzy” as if bark were made of acrylic sheets. 


Microscopes at right reveal details not visible to
the naked eye. It is the same universe.

Is Perception Infallible?

Consider Salmieri’s instructive example of the myopic man looking at a tree without his glasses. While he sees the same tree he would see if he was wearing them, he sees it blurrily, and this blurriness is part of the way or form by which he sees the tree. As Salmieri notes in his section, “Epistemology and the Nature of Awareness,” “An especially naïve realist would take the blurriness to be a feature of the very tree in front of which the man is standing.” Such a naïve realist is, of course, mistaken, for he mistakes a way he perceives an object for a feature of the perceived object. -- Concepts and Their Role in Knowledge: Reflections on Objectivist Epistemology, Allan Gotthelf, Editor; James G. Lennox, Associate Editor; Ayn Rand Society Philosophical Studies, University of Pittsburgh Press; 2013; page 217, “In Defense of the Theory of Appearing: Comments on Ghate and Salmieri,” by Pierre Le Morvan.

 Onkar Ghate is resident expert in Objectivism at the Ayn Rand Institute. He received his doctorate in philosophy in 1998 from the University of Calgary. Gregory Salmieri completed his doctorate at the University of Pittsburgh in 2008. Pierre Yves Le Morvan earned his Ph.D. in philosophy at Syracuse University in 2000.

It is not only my Objectivist comrades who are lost in the woods. This passage starts off sounding very technical, promising close analysis. In the end, though, it comes down to a sophomoric failure. It is well known that so-called “natural language” allows nonsense. And this is an example of it.

If philosophers were pursuing new knowledge, they would be formalizing the integration of perception across many transducers from your own senses to the most sophisticated instruments. How and why do all of these outputs describe the same objects? 

“A simple account teaches us that argument validity is a matter of truth-preservation: roughly, an argument is valid just in case the truth of the premises guarantees the truth of the conclusion. A bit more precisely, a set of sentences G of a language L entails a sentence s of L just in case, (for any model M), whenever all elements of G evaluate to the truth (in L, and M) so does s. Then we can say that an argument is valid, just in case (for all models), the premises entail the conclusion(s). On this account, then, entailment is characterized as a relation between sets of sentences and a sentence (a conclusion); and arguments are individualized as sets of premises and conclusion(s).

“But this simple account becomes instantly more complex once we are dealing with inference patterns in natural languages. One immediate problem is ambiguity. For instance, consider the following:

(1)   Ambiguity

a.     If John is at the bank, he will deposit a check

b.     John is at the bank.

c.     He will deposit a check.

“Suppose that ‘the bank’ in the big premise, (1-a) refers to a financial institution and in the small one, (1-b), to the bank of a local river.”

If a tree falls in the forest, they will hear it.

The failure of so-called “natural language” to explain the truly supernatural is an old lesson.  To hang an argument on a pun--bank versus bank; and no mention of turning an aircraft-- seems frivolous. 

(ii) Yet sometimes men are led by a natural tendency to think and speak of God as if He were a magnified creature — more especially a magnified man — and this is known as anthropomorphism. Thus God is said to see or hear, as if He had physical organs, or to be angry or sorry, as if subject to human passions: and this perfectly legitimate and more or less unavoidable use of metaphor is often quite unfairly alleged to prove that the strictly Infinite is unthinkable and unknowable, and that it is really a finite anthropomorphic God that men worship. But whatever truth there may be in this charge as applied to Polytheistic religions, or even to the Theistic beliefs of rude and uncultured minds, it is untrue and unjust when directed against philosophical Theism. The same reasons that justify and recommend the use of metaphorical language in other connections justify and recommended it here, but no Theist of average intelligence ever thinks of understanding literally the metaphors he applies, or hears applied by others, to God, any more than he means to speak literally when he calls a brave man a lion, or a cunning one a fox.

It is a fact that if all of the boulders, rocks, and stones between Mars and Jupiter were gathered into a single body, it would be the size of our Moon, hardly a planet, and yet we still call them “asteroids” as if they were star-like. The first quasar was identified as a pulsar. And Pluto is no longer a planet. And that is just one science. 


I have several books from the library on genetics. As much as we know, we still describe basic knowledge with footnotes and exceptions. Just for one fun fact: sometimes for a gene to be replicated the transcription RNA must “read” the molecule backwards. And yet here we all are, even if we do not know everything about how and why. 


Science proceeds by accepting ambiguity. Philosophers want to argue it away—in English. If you want to fall down the rabbit hole of analytic philosophy, read what many philosophers think that Immanuel Kant meant by “Das Ding an sich.” The problem is the word “an.” It sounds like “on” but it means “next to” or “nearby. “ Hans ist an den Wandtafel. (John is at the blackboard.) And it could be “in” “of” “with” and so on, depending on the context and the acceptance of idiomatic expressions.

Humans Will Live Beyond Earth, Thrive Well, and Travel Far

The discovery of seven likely Dyson Spheres suggests the possible existence of civilizations beyond our own. Whether or not that claim is ultimately supported, the fact that was made at all is an important element in the broader search for extra-terrestrial intelligences (SETI). It is highly unlikely that billions of galaxies with billions of stars most with planets all exist without intelligences, except for us here on Earth. Contrary to that, on the astronomy discussion board Cloudy Nights, Sky & Telescope editor, Tony Flanders, has been hosting an open exchange of opinions -- his own and from several other writers -- that overwhelmingly assert that human colonization beyond Earth is unlikely, or impossible, or unnecessary, or undesirable. I believe that it is inevitable. 

See here for the 40+ comments "Will Humans Ever Settle in Outer Space? - Science! Astronomy & Space Exploration, and Others - Cloudy Nights" https://www.cloudynights.com/topic/947257-will-humans-ever-settle-in-outer-space/ 


 Seven possible Dyson Spheres from 

MNRAS 531, 695–707 (2024) 

https://doi.org/10.1093/mnras/stae1186 

Advance Access publication 2024 May 6 

In that discussion, the objections to human colonization beyond Earth are that the environments of the Moon, Mars, Venus, the asteroids, etc., and the space between them all is worse than hostile: it is irremediably lethal because of the electromagnetic energies (“radiation”) that exist. (We are protected here by our magnetic fields and atmosphere.). Moreover, water is critical to life for us and rare almost everywhere else. And food must be created and no other planet has soil that is amenable to the lifeforms that we depend on. Having evolved in a gravity field, we find living in zero-gravity debilitating of our muscles and bones. And those are just the gross structures. At the cellular level, zero-gravity is just as bad for us, if not worse in the long run. We are not at all adapted to that environment.

Further objections grew from the economics of trade: there is none. In other words, spaceborne manufacturing so far has been in batches too small for commercialization. It has all been proof-of-concept, at best. Mining the Moon, Mars, or asteroids was also dismissed as difficult to impossible in the first place. Consequential to any success the economics of mining suggest that anything initially rare enough to justify the expense becomes too common to support it.

Overall, I found the objections especially disheartening because they came from people whose hobby is observational astronomy. They have the technical knowledge and special interest that I expect from enthusiasts rather than nay-sayers.

I can project several scenarios that take humans beyond Earth. All of them come from known science fiction and are merely extrapolations of known history, as science fiction must be: “if this goes on…”; “unless this changes…”; “if this takes over…”; “if this is forgotten…”; and so on. 

 1.     New propulsions. Beyond chemical rockets or plasma engines or huge sails, something we have not expected and could not expect but may be hinted at now will come along. We have had the steam engine, electric motor, internal combustion engine, jet engine, … balloons, airships, and airplanes … and the International Space Station. Something new but understandable in retrospect will change how people leave the planet.

2.    New technologies. The unexpected cross-use of existing tools will open new opportunities. The transistor is a case in point. The “transfer of resistance” by crossing two diodes solved one limited problem in one field. Now, we have power transistors pushing over 200 amps with potentials over 4000 volts. And we have very large scale integrated circuits with a million tiny transistors. 

3.    New biologies. The “people” who go into outer space may not be recognized as “people” today. Modified by microorganism that themselves were modified, they will be engineered to thrive in environments that right now are lethal to us. Those people will engage with symbionts that also were engineered for their environments. Not knowing fully what those ecologies will be, we could allow them to evolve through planned but open epigenetics.

4.    New sociologies. You do not need to take your tribe with you or go with them. Rather than as colonies and settlements, we may burst forth as a billion individuals. Individuals in individual carriers can be linked into complex social engagements. Some intelligent actors can be long-distance communicants while others will be mechanoids like dogs or cats aboard your ship. 

5.    Radiation is energy. The electromagnetic wavicles that are dangerous are also the dynamos that can power the transformations we need. Elements can be created and from them molecules. 

6.    Space is rich. Hydroxyl ions, water itself, and aromatic hydrocarbons are known to exist in outer space. Asteroids, moons, planets and their atmospheres are all sources of the materials upon which the abundant radiation can be put to work.

7.     New challenges. One complaint repeated is that there is no reason to go to Mars or the Moon, etc. And I can grant that. But I also point to the 7,269 people who have climbed Mount Everest—over 90% of them in the last 40 years. Some have died for lack of oxygen because the crowding prevented them from getting to their camps. In 1985 only one person had climbed the tallest summits on each of the seven continents. Now, it is regarded as “a popular challenge.”

The Light Ages: The Surprising Story of Medieval Science

It is difficult to know when to accept history on its own terms. We tend to not condemn the ancient Greeks, Romans, or Jews for having slaves, though we hold the ante-bellum South culpable. I was not surprised by Seb Falk’s story about Brother John Westwyk’s productive labors in mathematical astronomy and the consequential instrumentation of measurement for those works. But I was enlightened by the search for and discovery of the man who wrote an astronomy text commonly credited to Geoffrey Chaucer. 

Chaucer did author A Treatise on the Astrolabe. It was Dompnus Johannes de Westwyke (Brother John of Westwick) who created Equatorie of the Planetis, a book that had been credited to Chaucer. So, Seb Falk interleaves two stories here: the life of Brother John as best it can be built from scant records; and the development of astronomy (and, generally, science) in the Middle Ages. 

Reading this book the first time through, I knew that I would annotate post-its to bookmark passages. The second time through the book, it soon became clear that I should just copy the whole thing here—which, of course, is not allowed.

“Far from the stereotype of a stagnant scientific environment which did no more than preserve the ideas of the ancients, computists in the twelfth and thirteenth centuries continued to refine their astronomical models, with ever more accurate estimates of the solar and lunar cycles. Scholars became more outspoken in their criticism of the increasingly unrealistic ecclesiastical calendar. In the 1260s Franciscan friar and proponent of empirical science Roger Bacon wrote, at the Pope’s request, a series of tracts on educational reform.” (page 74) 

To compute, you must have a computer. God gave you ten fingers, each with two knuckles. Supported and enhanced with recipes for rapid mental arithmetic, you could calculate the rising and setting of the Sun for your locale—and you could measure musical harmonies, also. If you were enrolled at a university in 1325, to complete a bachelor’s degree required completing the Trivium of Logic, Rhetoric, and Grammar; the master’s degree required the Quadrivium of Geometry, Arithmetic, Music, and Astronomy. But attending one of the newly founded universities was expensive. So, monasteries most often paid for a limited education after which the motivated monk studied (and wrote) on his own—and sometimes her own (page 73). 

 

One result of that was that no two books are exactly the same. Copyists used the intentionally available spaces to add their own amendments and emendations, expanding, explaining, and correcting. Books lived. (ref. esp. pages 77 and 124). Knowing this, and expecting that copies will be carried to other places, Brother John Westwick cautioned the next one building an equatorie from his plans: “Nota I conseile the ne write no names of signes til that thow hast proved this commune centre defferent is trewli and justli set.” (Illustration 7.9).


The Light Ages: The Surprising Story of Medieval Science by Seb Falk; W. W. Norton & Company, New York, 2020. (Published in the UK as The Light Ages: A Medieval Journey of Discovery; W. W. Norton & Company, London, 2019.) W. W. Norton's webpage mentions the Best Book awards from The Times, The Telegraph, and BBC History Magazine. I learned of it because it garnered the AAS Historical Astronomy Division Osterbrock Book Award for 2024.


One thread not followed here, which I considered important, is that the manuscript under discussion was first rediscovered by Derek Price deSolla. Price deSolla is also credited with the first rigorous examination of the Antikythera Mechanism (NecessaryFacts here.) No mention of that appears in this book.

Christmas 2024

In our neighbood, Steeplechase II, in Kyle, Texas, the Christmas lights started sprouting right after Halloween. The best graveyard changed the headstone to Ebenezzer Scrooge and added reindeer and very much more. 

Our House is a Very, Very Fine House

When we moved here at the end of 2020, I had lights up at two homes. This year, I changed one string of Thanksgiving colors and I used as many Christmas lights as our home would carry.

Created Works and the Public Domain

Public Domain Day 2025 came up as a Google News item. I have given some thought to the traditions and laws about intellectual property and I have only questions. In other blog posts I commented on the contradictions, but I have no integrated proposal. 

Common assumptions about property are rooted in the physical reality of land: it is impossible for two objects to be in the same place at the same time. Thus, land is rival and exclusionary: if an entity (person, family, etc.) possess it, then another cannot. Copyrights and patents attempt to include “ideas” into “lands.” However, intellectual property is metaphysically different from physical property. 

 Based on the definition that property ownership is rival and exclusionary, collectivist thinkers built a truth table to show Common Resources (excludable but non-rival) and Club Goods (rival but non-excludable). That is nonsense. 


Define Human as “rational animal” and the non-rational animal and rational non-animal remain not-human. So, too, are common resources and club goods not property. Non-A cannot be A. Nothing is not a different kind of something.


Contrary to the collectivist claims, freshwater, fish, timber, and pasture are all exclusionary and rival. You can’t have your fish and let your neighbor eat it, too.

 

What they call “club goods” are defined and limited by technology, not by metaphysics. Discussing radio broadcasting in her essay, “Property Status of the Airwaves” Rand correctly pointed that two broadcasters cannot share same frequency. But they can. Just not at the same time. And time-slicing allows two (or more) broadcasters to occupy the same wavelength. However, that does not change the fundamental principle that these timely-sliced increments are property.

Common resources – non-excludable but rival (freshwater, fish, timber, pasture)

Common resources are defined as products or resources that are non-excludable but rival. That means virtually anyone can use them. However, if one individual consumes them, their availability to other consumers is reduced. The combination of those two characteristics often results in an overuse of these resources because demand exceeds the available quantity (see also the tragedy of the commons). Examples of common resources include freshwater, fish, timber, pasture, etc. -- https://quickonomics.com/different-types-of-goods/

 Club goods – excludable but non-rival (cable television, cinemas, wireless internet, toll roads)

Club goods are products that are excludable but non-rival. Thus, individuals can be prevented from consuming them (i.e., access can be restricted), but their consumption does not reduce their availability to other individuals (at least not until a point of overuse or congestion is reached). Club goods are sometimes also referred to as artificially scarce resources. They are often provided by natural monopolies. Examples of this type of goods include cable television, cinemas, wireless internet, toll roads, etc. -- 

https://quickonomics.com/different-types-of-goods/

 

It is true that you and I can both watch the same program on cable-TV. The hidden error was identified by Ayn Rand as “the blank out” and Rand identified its logical expression as the fallacy of the stolen concept. You and I can both watch the same cable-TV show – up to a point: we all know what happens when too many users overload a website. More deeply and cogently, for anyone to access television or the internet, physical goods must be produced. The perception of social largess as a “club good” blanks out on the previous non-existence of roads and theaters.  

We [the American Historical Association] encountered a similar experience in 2001, when the AHA decided to create a freely available online collection of Civil War newspaper editorials, utilizing two volumes originally published by the AHA in 1931 and 1942. AHA staff quickly discovered that no copyright renewal was ever filed for the second volume, edited by Harold C. Perkins, and it subsequently had entered the public domain. However, the editor of the first volume, Dwight L. Dumond, had renewed the copyright in his own name in 1959. Orphan Works Notice of Inquiry – 70 Federal Register 3739 (Jan. 26, 2005)

http://www.copyright.gov/orphan/comments/OW0676-AHA.pdf

To me, the error was the granting of the copyright to Dwight L. Dumond. As the editor, he was a hireling. His work rightfully belonged to those who paid him for it. The concept of a collective entity in law –what we call a “corporation”-- has roots in the Roman republic. Under Roman law, a flock of sheep was a collective entity: lose a lamb or gain a lamb, it is the same flock. On that basis, cities were taxed: the city was an entity that owed tribute to Rome, itself a collective entity. No one owned a city. Under American law, the American Historical Association as an entity can certainly be protected from theft by its employees. 

 

On or about the same day as the link about Public Domain Day, Google News offered a link to a story from GameRant.com about the Star Trek canon. Star Trek is owned by Paramount Global. (The July 2024 merger with Skydance may be challenged now through the FCC but that does not affect what follows.) Since 1966 many details of the continuing, expanding, and extending myth have been changed. Others remain constant. In this case, the legal owners changed an element of the canon - the physiognomy of the Klingons was altered in Star Trek: Discovery and the fans objected. (Klingons had changed once already but that was accepted.) Using a new storyline in Star Trek: Lower Decks, the owners offered some technical explanations for the change. 

 

To me, that is all good because myths change in the retelling. Mythology allows that: characters can merge or split; new characters can be entered while established characters leave. Star Wars: A New Hope is just the Wizard of Oz: Luke is Dorothy; R2D2 is Toto, … But in Star Wars, one aspect of the Wicked Witch (Darth Vader) is saved while the other aspect of the character (the Emperor) perishes. That begs the basic question: Who owns Star Wars or Star Trek or Harry Potter?  At what point does the creation of intellectual private property enter the public domain? Is there such a point? 


Back in the early 2000s, before the Atlas Shrugged movies were released, a Rand Fan created some Atlas Shrugged swag, a Rearden Steel trucker's cap, etc. The Ayn Rand Institute sent her a lawyer letter reminding her that the artifacts were based on the copyrighted works of Ayn Rand. So, as an Objectivist herself, she ceased and desisted. But we cannot imagine Paramount chasing down every "Beam me up, Scotty" bumper sticker. And personally, I think that the ARI should have just shrugged it off by labelling their gear "Official" the way that Major League Baseball does.

I have donated to the Internet Archive and the Wayback Machine. (Similar archives include the Hathi Trust and the Linda Hall Library.) Like the promoters of Public Domain Day, my comrades at the Internet Archive claim a moral high ground because they are offering the works for free and have no commercial interest in the use. To me, that argument is irrelevant. And it is falsified by several considerations. They do accept donations, and it is easy to assume that donors are users. Absent donors, the entity would not exist. So, they are in business. And in business for a profit because not-for-profit is only a matter of bookkeeping: owner's equity is called "net assets."


Long ago, writing in The Libertarian Connection, Skye d’ Aureus and Natalie Hall argued against Ludwig von Mises’s assertion that truth and beauty are not economic goods. Skye and Natalie pointed out that truth and beauty must be produced by human action.  

As collectivism grows in popularity, and as the nonproductive consider themselves increasingly entitled to the wealth created by the productive, Rand’s arguments in favor of intellectual property rights merit reinforcing not diminishing. -- "Ayn Rand's 'Patents and Copyrights'" by Marilyn Moore, posted May 28, 2019.  https://www.atlassociety.org/post/ayn-rands-patents-and-copyrights

Writing for the Atlas Society, Marilyn Moore (Director of Student Programs) parsed the difference between copyrights and patents and argued contrary to Rand that literary works should be patented while inventions should be copyrighted.  Moreover, Moore asserted, as a metaphysical fact, a discovery cannot be patented or copyrighted. First, the discoverer did not create the fact; and, second, once announced to the public, the discoverer cannot prevent other people from now knowing what they know. Third--and most consequentially--it is immoral to deny independent discovery and therefore independent invention. It is unlikely that two people will write the same book. It is well known that two people can create the same solution to a technical problem based on a shared (though independent) understanding of the facts of reality.
