Life

The musical group, R.E.M.’s most popular song is arguably “Losing My Religion.” The first two lines of the lyrics are, “Life, it’s bigger; It’s bigger than you.” It’s bigger even than our homo sapiens species. I sing that song periodically in karaoke, though as too many people in charge of karaoke are corrupt in that they slide in their friends, new arrivals, and even regulars into rather than at the end of the line, I go less and less often. To an ethicist, corruption even on that small level is intolerable, as indeed the mentality of such a DJ is culpable. It is easy to commit the fallacy of anthropomorphizing unethical, sordid intent onto other species, especially with regard to their biological need to feed in order to survive. In the film, Life (2017), astronauts, a physician, and a scientist on board a space-station orbiting Earth wisely avoid precisely that fallacy even though a species from Mars being cultivated by Hugh Derry, the scientist, feeds on all but one of the six humans on board.

Don't Look Up

The film, Don’t Look Up, is a most interesting film not only for how it relates science to political economy, but also in that images of wildlife—Nature, as it were—are interspersed throughout the movie, and it is Nature, rather than our circumscribed, petty, and yet economically successful species, that continues on after a large comet hits Earth and our species is wiped out. In fact, that impact-event in the movie cancels out the one that really happened 66 million years ago by returning dinosaurs to dominance. The last scene in the movie shows some of the political and economic elite waking up in their spaceship and landing on Earth more than 200,000 years in the future only to be eaten by dinosaurs that look "cute." two of those stupid people had been in charge both in the White House and in business before the comet hits, whereas the two principal astronomer-scientists who warn of the coming comet are repeatedly relegated and dismissed by the political and economic elite until the president realizes how she can use them politically—albeit just until the political winds turn again and comet-denial is more useful politically to the president. Does this sound familiar?

The Summer Solstice: Astronomy Is Not Meteorology

It boggles the mind that the same meteorologists who know that June, July, and August days are counted when calculations are made on the average temperature for summer nonetheless broadcast the summer solstice that falls three weeks into June as the first day of summer. To do so in the context of weather forecasts is nothing short of intellectually dishonest. To an unfortunate extent, those meteorologists may simply be following the herd of tradition at the expense of thinking for oneself. The human brain is suited for much more than a herd-animal mentality.

Undermining Progress: Power Enforcing Infallible Ignorance

Bleeding to heal. The Earth is flat. Earth is at the center of the solar system. Zeus lives on Mount Olympus. The divine right of kings to act even as tyrants (e.g., Henry VIII of England). Hitler died in his bunker. Turning the heater on in a local bus kills coronavirus. These are things that were thought in their respective times to be uncontrovertibly true. In some of these cases, the power of the establishment was not subtle in enforcing them even when they should have been questioned. How presumptuous this finite, mortal species is! If ignorance on stilts is bliss, then why is it such in need of power? Subconsciously, the human mind must realize that its assumption of not being able to be wrong is flawed. We are subjective beings with instinctual urges—one of which manifests in the unquestioned assumption that what we know cannot be wrong, and furthermore that we are entitled to impose our “facts” on others. As the homo sapiens (i.e., wise) species, we are too sure, and too proud, concerning our knowledge and especially beliefs. We would like to have the certainty and objectivity that computers have, but we are subjective biological animals, not inert machines.

Climate Seasons and Astronomy Confused: A Societal Blind-Spot


In the Northern Hemisphere, in the Northern E.U. and U.S., it is ludicrous to claim that winter begins not until December 21st. If we go by the claim, the Christmas season is in the fall—joined by Halloween (and Thanksgiving in the U.S.). Similarly, September sports autumn cooling off rather than three more weeks of summer. In many areas, leaves turn fall colors well before September 21st. As a matter of fact, “Climate scientists define summer as the three months from June 1 through August 31st.”[1] Why, then, do meteorologists on television, at least in the U.S.—that vaunted superpower—announce that fall officially begins on September 21st. They even show “fall begins” on the day of the 21st on the week of weather. Similar, the fools show “winter begins” just four days before Christmas, on the winter solstice. That solstice is in the winter—not the beginning of it.

Political Black Holes: On the Power Behind the Throne

Our galaxy, the Milky Way, has a black hole. If this is news to you, there is no need to go hide under a rock. It turns out our black hole is not the biggest by far, and it doesn't spew out a lot of excess energy that falls into it. Even so, it is ours, and we can be glad that we have one of our very own even if it isn't the biggest one on the block. In case you are interested in seeing it’s baleful look in a picture, I’ve got bad news for you; it is invisible. No light can bounce off it.  You are probably wondering how the scientists found it.  Well, they knew that black holes are in the center of galaxies, so the crafty lab coats used invisible light to find our center because there is too much gas there for much there to be visible to us.  The scientists noticed that the speed of stars speeds up around a certain point and posited the existence of a highly-dense black hole.

Getting the Seasons Officially Wrong: A Case of a Category-Mistake

Joel Achenbach of the Washington Post has not quite turned the corner with respect to spring, and the seasons in general. You see, “season” is used in two distinct though related ways in English. It can refer to four distinct weather/plant-life conditions or to the four parts of the earth’s orbit around the sun. Given the tilt of the Earth, the two are related but they do not occur together. While Achenbach acknowledges that the vernal equinox typically on March 21st “is a moment of time specified by the motion of the Earth around the sun,” he refers to this as the official start of the meteorological spring. In actuality it is not. In the Northern Hemisphere, meteorologists record data from December, January and February as winter and March, April and May as spring. So in March 2012, meteorologists could already conclude that the preceding winter had been the fourth warmest since the record-keeping began.

A Comet’s Cosmic Song: Evidence of Plato’s Justice as Harmony of the Spheres?

On September 30, 2016, the European Space Agency’s Rosetta spacecraft ended its mission orbiting Comet 67P. The mission added knowledge on how planets came together and how life arrived on Earth. “One of Rosetta’s key findings is that comets are probably not the source of Earth’s water.”[1] I submit that of even greater importance is a finding that can be indexed as philosophical in nature.

Increasing Complexity and More Energy in the Context of Evolutionary Biology

In “the story of increasing complexity and then decreasing complexity,” we find complexity in “privileged localities” where “intense local flows of energy that are dissipated elsewhere, where things are less complex. . . . So increasing entropy in one region seems to allow decreasing entropy—that is to say, increasing complexity—in some very special regions, such as the surface of our Earth.”[1] Differentials in the universe began in the random, unpredictable differences at the sub-atomic level at the very beginning of the Big Bang.  It took 380,000 years for tiny differentials in temperatures and mass-densities to show up in the cosmic radiation background. Since then, much steeper energy-gradients have developed, and these have enabled greater complexity to arise and subsist.
Contemplating the enigma, wherein increased complexity and the associated additional energy required occurs amid a more general entropic process of a flattening out or dispersion of energy in the universe as a whole, can lead to the question of whether the level of complexity now extant in human civilization is a work in progress or a pinnacle. That is to say, will hitherto undiscovered sources of energy boost human arrangements and infrastructure—artifices of human intentionality—to higher levels of complexity? At a much longer temporal scale, will the Milky Way gain in energy and complexity as a result of incorporating a passing galaxy? In both cases, I marvel at the enigma wherein steeper energy gradients serve as more efficient energy conduits on the way to an entropic final destination. 

This history of life on Earth is a tale of increasing biological complexity. A single cell is more complex than is the Sun and our planet. From the Cambrian period, the diversity of plant and animal organisms has expanded so much from the common one-celled ancestor that we can say with Plotinus, "(I)t is a wonder how the multiplicity of life derives from what is not multiplicity, and the multiplicity would not have existed unless what was not multiplicity had not existed before the multiplicity."[2] What we typically forget is that with each increase in biological complexity, more free energy is necessary to sustain it.  
In human history, the capture of energy from the Sun for our species’ use has increased dramatically from the hunter-gatherer days to today. The leap afforded by the Neolithic Revolution, when nomads—taking advantage of “Garden of Eden” conditions—began sedentary, agricultural lives, is dwarfed by the tremendous jump in energy-usage from fossil fuels in the Industrial Revolution. The change in technological and organizational complexity due to the Industrial Revolution far exceeds the increase in complexity that came as a result of the Neolithic Revolution.
Because 95% of our species’ time on Earth was spent in the hunter-gatherer, small clan, social arrangement, the incredible leap in energy usage (now 100 times what is needed for survival, per capita) from fossil fuels whose stored energy far exceeds the potential energy of animals and human labor, and the related leap in complexity in spheres such as business, government, and society (e.g., large cities) during and after the Industrial Revolution makes us fish out of water, evolutionarily speaking. That is to say, natural selection—the mechanism discovered by Darwin whereby a changed environment “selects” mutations that are more favorable to it—has not had enough time to adjust our species to the world that we have created.
For instance, we are “hard-wired” for having contact with up to 150 people because that’s how big clans got during 95% of the time that natural selection has had to fashion our species via incremental alterations or adjustments. We are fish out of water in the cities we ourselves have built. Similarly, natural selection is too long-paced to alter our innate short-sightedness such that we can apply collective learning to obviate the threats to our species’ survival from our energy use, such as in climate change. In short, the increasingly large leaps in the steepness of the energy gradients enabled by our successively rich energy-sources have by now outstripped the energy of our evolutionary biology being able to “catch up.” Put another way, our amazingly complex biology—far from the Cambrian Revolution that led to the diversification of life—is not in sync with the complexity that we have constructed to make our lives easier and even happier.

Interstellar: Being in Love as a Black Hole

As difficult as it is to grasp the nature of a black hole and its all-consuming gravity, Interstellar (2014) also traces the powerful yet mysterious gravitational pull of human love, including that utterly unfathomable condition we know as “being in love.” We fall in love, which is an expression that presupposes gravity. Yet such all-consuming attachment may not even in principle have as its object our species itself. Even falling in love may be dangerous—just look at Shakespeare’s Romeo and Juliet.

God Versus Physics: Is Creation Behind the Big Bang?

In his doctoral dissertation, Steven Hawkins demonstrates that the universe could have begun spontaneously. That is to say, the big bang could have gone off without being triggered by a divine intelligent being, or God in the sense of the word as used in the Abrahamic religions. To say that the universe could have begun in a moment of singularity is not necessarily to vitiate the deity-concept of all content. In fact, Hawkins’ work may one day trigger a movement to hem in the concept to the terrain that is distinctly religious.

Agora: Putting Religion in Perspective

Film has the potential to be so engrossing perceptually for the viewer-auditors that the medium can engage the human condition at a deep, unconscious level. At that level, the subconscious protects us in the games we so seriously play.  If done well, film-making crafts a coherent and complete story-world into which the voyageur can be temporarily lodged before returning to the ordinary world that now looks somehow different. The subtle perceptual change can result from part of the viewer’s subconscious having been made transparent, or realized, while in the film’s story-world. As concerns the religious domain, I contend that the medium has only touched the surface in holding a mirror up to ourselves. This is not to say that more anti-religion movies, such as Last Temptation of Christ, are the answer; neither are more palliative, apologist films, like The Ten Commandments and The Greatest Story Ever Told, the way to greater self-awareness for homo religious.  On account of their un-questioning, one-dimensionality (even when viewed with 3D glasses!), these films are more alike than their respective leitmotifs would suggest. Most importantly, none of these films raises penetrating questions that assume the validity of “the other side.” Nietzsche advocates approaching truth itself as a problem rather than as something whose validity is held to be beyond question (i.e., sacred).  A film can subject truth itself as a problem (rather than as a conveniently partisan given) and enhance, thereby, human awareness of just what we are up to when we take ourselves as religious, whether in self (or group) identification or conduct. Once a film gets a grip on a truth and makes it a problem rather than a pallid backdrop, you can bet the river Styx in the human unconscious will be stirred, lapping over its banks as it tries to order its new-found energy gained from the antiseptic sunlight. My question here is whether Agora transcends below the patina of reactionary anti-religion films to widen our collective consciousness at the expense of hypocrisy and denial.

Meteorology vs. Astronomy: Is It Spring Yet?

Advancing clocks an hour ahead to Daylight Savings Time conveniently announces itself as the easy-to-remember Spring Forward. Advancing democracy in the Middle East in the early years of the 2010s proclaimed to the world the Arab Spring. Advancing global warming foretells earlier springs encroaching on softened winters. Even as spring blooms in the sights of the popular press, the media quite stunningly often stumbles over when the season begins. The groundhog is no help, differing from year to year on whether spring begins four or six weeks from February 2nd. Astonishingly—and in no small measure my impetus in writing here out of no less than dumbfounded curiosity—even television meteorologists play to the popular ignorance, willingly succumbing to the common practice of taking astronomical “spring” as meteorological spring too. The “professionals’” declaratory tone alone reveals just how certain human beings can be even of presumed knowledge lacking any real foundation.  Sadly, this mentality of assertion, having become so widespread, or ubiquitous, in modern society, is virtually invisible to us; and yet, the shrill of the epistemological missionary zeal reverberates from no less than modernity’s default: faith in one’s own use of reason. In this essay, I present the first day of spring as a case in point rather than make the entire argument.

Sometime during the first week of March 2014, as yet another front of frigid Arctic air charged southward through North America, various weather personalities on television newscasts relished in the apparently startling fact that spring was just two weeks away. Viewers looking out at snow-covered landskips as far south as Kansas City could marvel at the return of nature’s colors and smells so soon. Most years, the grass is green there by the Ives of March.

Even as the popularly broadcast juxtaposition made for good copy, meteorological spring in the Northern Hemisphere had already come—that is to say, with regard to weather and climate. According to the U.S. National Oceanic and Atmospheric Administration, “(m)eteorologists and climatologists break the seasons down into groupings of three months based on the annual temperature cycle as well as our calendar. . . . Meteorological spring includes March, April, and May; meteorological summer includes June, July, and August; meteorological fall includes September, October, and November; and meteorological winter includes December, January and February.”[1] Therefore, by the first week of March 2014, spring had already arrived as far as the weather is concerned even as television meteorologists were publicly pointing to March 20th as the first day. 

Even calling so much attention to the first day, as if suddenly the northern climes of the contiguous United States would suddenly return their fauna and flora to their other half-lives on that day, is horribly misleading. Assuming that the meteorologists were well aware that spring weather data begins on March 1st of each year in the U.S., the next-most plausible explanation may be found in the lazy assumption that it is easier to go with popular misconceptions than expend the effort to stare one in the face and overcome its stolid inertia head-on (the excuse being not wanting to cause confusion).

As a result, Americans are left with the incredibly incongruent “expert” assertion that summer begins not with Memorial Day, but just a couple of weeks before July 4th on June 21st of each year. Essentially, we are to believe that summer begins in the middle of summer! That such a logical and experiential absurdity can long endure in spite of evidence to the contrary is itself evidence of just how much cognitive dissidence human beings are willing to endure in the face of declarations from perceived expertise. In other words, an erroneous or outdated status-quo societal default has tremendous hold even in the age of (rationalist) Enlightenment (i.e., from the fifteenth-century Renaissance period).

Lest it be said that the enabled popular misconception came spontaneous out of nothing ex nihilo, the basis of the confusion lies in the rather stupid decision to apply the names of the meteorological seasons (i.e., fall, winter, spring, and summer) to the four quadrants of the Earth’s orbit around the sun. Whereas the meteorological seasons are based on the annual temperature cycle applied to the calendar, “astronomical seasons are based on the position of the Earth in relation to the sun.”[2] Due to the tilt of the planet, solar energy is maximized in the Northern and Southern Hemispheres in different parts of the planet’s orbit. To label a certain interval of space as “spring” is not just highly misleading; the label is a category mistake, for the climatic seasons on Earth do not exist in the void of space.[3]

Astronomy is distinct from weather, even though the two are related (i.e., not disparate).
(Image source: NASA)

Put another way, astronomical “spring” in the Northern Hemisphere refers to the portion of the Earth’s orbit from the point at which the vertical rays from the Sun hit the Earth on its equator (on the “Spring” Equinox, usually on March 21st) to point when the vertical rays are on the Tropic of Capricorn (the furthest north the vertical rays go, on the “Summer” Solstice, usually on June 21st). In fact, Summer Solstice is better translated as the highpoint rather than beginning of summer. That is to say, the sun reaches its highest arc in the Northern sky on June 21st, which is neither the pinnacle nor beginning of summer in terms of temperatures.[4]
 
In short, the piercing pronouncements on the public air-waves of the beginning of spring (and then three months later of summer) ring hollow. Nevertheless, the meteorologists who trumpet the good news do so year after year, as if deer caught in a car’s headlights (or speaking to such deer!). Perhaps the fix is as simple as changing the names of the Earth’s orbit’s four parts so they are not likened to climatic seasons. The puzzle would doubtless still present itself as to how it is that nonsensical claims can long endure as a societal (or even global) default, taken for granted in a way that strangely wards off reason’s piercing rays and those of our own experience. Something is oddly off in how human beings are hard-wired.

[3] As another example of a mislabeling that should have been known to trigger much confusion and even false claims, the three law instructors from Harvard who founded the law school at the University of Chicago at the beginning of the twentieth century should have known better than to replace the name of the bachelors in law, the L.L.B. (i.e., bachelors in the letters of law), with a name implying a doctorate (the J.D., or juris doctor). The actual (professional and academic) doctorate in Law is the J.S.D., the doctorate in juridical science, of which the LL.B., or J.D., along with the LL.M. (masters), is a prerequisite and thus not possibly a doctorate in itself. A doctoral degree must be the terminal degree in a school of knowledge, have comprehensive exams in a discipline of said knowledge (graded by professors rather than an industry regulatory body), and include a significant work of original research (i.e., a book-length study, except in a quantitative or scientific field) that the candidate defends before a committee of faculty. Yet how many Americans correct an American lawyer who declares himself to be a doctor?  The same goes for the M.D. as well (a program of survey-courses followed by a couple years of seminars—the typical substance of a bachelors program), and yet how many physicians and surgeons presume themselves entitled to use the doctoral title (Dr.) even as they dismiss the valid appellations that holders of the Ph.D., J.S.D., D.Sci.M. (Doctorate in the Science of Medicine), D.B.A. (business), D.D. (divinity/theology), and D. Ed. (education) use as per the rights and privileges of these doctoral degrees?  Meanwhile, the general public goes on grazing as if the snow were green grass.
[4] The word solstice in English comes from the Latin word, solstitium, which combines sol (sun) and stit (from sistere, to make stand).  In other words, the sun is made to stand (highest) in the Northern Hemisphere on June 21st of each year. Nothing is thus implied about any beginning; rather, the implication is that of a pinnacle or high point. Yet even in this sense, meteorological summer is different, for its high point in terms of temperature comes in mid to late July.
