It really MIGHT depend on what the meaning of the word "is" is. (Reposted)

Reposted from the Ontological Comedian

If you think every word has a definition, and definitions are how we know what words mean, consider the word "is" -- which is a pivotal part of every definition -- indeed of the very idea of definition. A bear is a large furry mammal that sometimes walks on it hind legs, etc., etc.

The Big Lie again: "Holiday Trees" and Steven Levy "commentary"

 The following is going viral again as it apparently has around every Christmas of the past few years
http://www.truthorfiction.com/rumors/l/Steven-Levy.htm#.VIDWCUrUhLU

The above sources says it is based partly on a screed by Ben Stein, which is easy to believe considering other things he's written.

Apparently the White House referred to Christmas Trees as Holiday Trees for the first time this year which prompted CBS presenter, Steven Levy, to present this piece which I would like to share with you. I think it applies just as much to many countries as it does to America.

I have no idea where the concept came from, that America is an explicitly atheist country. I can't find it in the Constitution and I don't like it being shoved down my throat...

What is Science and What Can We Learn From it About Keeping Our Heads on Straight Generally.

Here are three posts trying to make some contribution to philosophy of science and to the public's understanding of it.

The first, What is A Machine? Natural Machines and Origins of Science tries to express something possibly original about the occasions when people have gotten a foothold on the path to a major branch of science.  Before the scientific revolution there were, hidden amidst the blooming buzzing confusion of nature, a few "natural machines".  Unlike the typical object in nature, they behave with predictable simplicity, although this may not be obvious for a long time -- until certain concepts and technologies aid in their analysis.  These include a heavy dense projectile in (parabolic, as it turns out) flight, and the system of the Earth, Sun, moon, and planets (and their moons).  Probably, I should say machines and mechanical processes, but I like the idea of a flying rock or cannonball as an ultra-simple machine.

The next essay, Finding Your Invisible Elephant. A Science Requires, and is Shaped by, a Tractable Subject Matter suggests that "scientific method", or other good epistemic processes such as peer review journals and conventions are not enough.  Once a discipline, through a fruitful set of techniques, is able to repeatedly find its way to make contact with a coherent set of fundamental facts of nature, only then do the practices of academia give rise to a ratcheting mechanism that can make the diverse efforts of many autonomous individuals and groups converge on better and better understanding of some set of phenomena.  This does not work for literary criticism, and its working in many fields of social science, such as sociology of scientific knowledge, is highly dubious.

The third essay, Global Warming and the Controversy: What is Scientific Consensus? Continental Drift as Example focuses on a case study of scientific consensus by a practitioner of the fairly new field of social epistemology, Miriam Solomon in her book Social Empiricism.  It concerns the gelling, over several decades, of recognition of the phenomenon of continental drift, or plate tectonics.  Many very diverse disciplines had to finally agree that they all had data pointing to the same surprising phenomena before it could legitimately be said that there was a scientific consensus.

Now, this falls short of what the title seems to promise, but is part of a project of trying to take small, sometimes painful steps in that direction.

Global Warming and the Controversy: What is Scientific Consensus? Continental Drift as Example.

    One common way of attacking the mainstream of climatology for its "global warming consensus" is to claim that consensus is just that sort of authoritarian "group think" that Galileo confronted in the Inquisition.  A companion claim is that mainstream climatologists have abandoned "the scientific method".  Some of those who say they have a case against AGW are likely to say that they are practicing the true "scientific method" and anyone who doesn't accept their experiment(s) or studies as decisive must be rejecting the scientific method.  They may also delve into the mainstream studies.  Global warming dissidents (who rarely sound to me like true skeptical thinkers) often cite studies by scientists who would be surprised to learn that anyone is saying their study disproved AGW, so it is often not scientists, but "science critics" claiming the scientific method has been abandoned by mainstream climatologists.  One person with whom I recently argued (on Facebook) said "When I went to college and took experimental psychology, the premise of experimentation was to challenge existing theory" and later "There is a scientific experimental process ... propose a postulate, select your population or test material, identify and isolate variables, run your test, draw conclusions, repeat, publish, then stand up to challenge."

Gerrymandering Viewed as a Nonpartisan (or rather pro-electorate vs the system) Issue

The difficulty we have with gerrymandering is that it will always seem attractive to the party in power. Common sense reforms should make us all feel we have more of a chance of being represented. Redrawing the map by both sides has one big nonpartisan effect; it is overall very good for incumbents. It tends to make every district a "safe" district for one party or the other. Another effect, sometimes in competition with the first is, due to "safe" districts, primary elections become very important; general elections much less so. During the primaries, candidates must try to "click" with one group riled up enough to turn out for primary elections. So you are far less likely to get people with balanced perspectives. In this age, balance or moderation tends to be ridiculed by both (or all) sides. But it is the way of getting the best from multiple perspectives. It gives you people able to argue fruitfully, not just posture for the "base". In reality, sometimes the more conservative idea fits the situation best, and sometimes the more visionary idea does. If people can fruitfully argue, we are more likely to get the benefit of that. I believe you are also more likely to see flaws (to missing the mark or just excess complexity) corrected in some legislation with more moderates rather than the attitude extremists often have "We won't cooperate to improve it because we like it being as bad as possible because we want it to fail" (see http://tinyurl.com/pf2z4qx). What would an alternative to eternal gerrymandering look like? Maybe laws that say a district should have a certain geometric compactness. That is something  where an intuitive concept could be represented by a mathematical formula. We might not understand the formula, but by looking at examples of what conforms to it and what violates it, we could see whether results look intuitively right. Better yet, in my opinion, we might introduce an arbitrariness, according to a mathematical formula. If you had a square state (which we don't of course) it could look like a checker board. Actually this doesn't quite work because it won't give you districts of approx equal population within a state, city, or county to be "districted" More sophisticated mathematics could generalize that formula. Another reason for putting it all in the hands of a mathematical/computer best line-drawing system that we can judge intuitive by the intuitive pleasingness of the results: it eliminates the considerable amount that can be done to create solid incumbancy districts (Dem districts or Repub. districts, or white, black or Latino districts) while the districts still look nice and geometrically compact. I believe some decades ago, gerrymandering, or rather drawing maps heavily relying on human judgement to attain some electoral tendency, regained some respectability when they were used to increase the chances of certain minorities getting a representative who looked like them. Lani Guinier, a legal scholar nominated by Clinton for Attorney General had some ideas for allowing such possibilities without distorting the electoral map in any way. They involved a sort of one man, N-vote sort of system, which was quickly vilified (as was Guinier) as a violation of the sacred 1-man 1-vote principle; but it did not violate it at all in spirit. Besides anti-gerrymandering, another common sense reform principle driven by the goal of real representativeness (not favorong one ideology or the other) is to reduce the role money plays. In http://therealtruthproject.blogspot.com/2014/08/might-it-be-possible-to-tune-out-or.html I proposed a model for this, suitable for growing up from the "grass roots" *if* the idea and trial results can over time persuade enough people. One example of money in politics that a conservative might be able to relate to is how much of a farce the 2012 Republican presidential primaries were. There were several instances of one candidate being up in one state and another in the next that looked less like the states having different ideological tendencies, and instead seemed explanable by someone having just bought a few million dollars worth of ads through one PAC or another. E.g. Sheldon Adelson bringing Newt Gingrich up from out of nowhere to near the top for a couple of days. Adelson is a casino magnate whose main issue these days is to suppress online gambling.

Finding Your Invisible Elephant. A Science Requires, and is Shaped by, a Tractable Subject Matter

The story of the blind men and the elephant comes from India.  One version, in Wikipedia follows:

Six blind men were asked to determine what an elephant looked like by feeling different parts of the elephant's body. The blind man who feels a leg says the elephant is like a pillar; the one who feels the tail says the elephant is like a rope; the one who feels the trunk says the elephant is like a tree branch; the one who feels the ear says the elephant is like a hand fan; the one who feels the belly says the elephant is like a wall; and the one who feels the tusk says the elephant is like a solid pipe.

Some may see it as a parable about the impossibility of knowledge, but the way I look at it, with enough blind men operating under the incentive structure of science, comparing notes, arguing this interpretation and that, they would eventually "get it" perhaps making a clay model of an elephant that one person could get their hands around.  Of course if they are no good a listening to each other, or lack persistence and/or the right sort of discipline this won't happen.

Previously, I wrote about how the few rare "natural machines" like the solar system have been a major factor in bringing sciences into being.  Now I'd like to suggest a different metaphor and try out the notion that the keystone of a science is finding its invisible elephant.  Rather than make all scientists blind, I'd rather make elephants invisible.

What does it look like when we are failing to find our elephant?  Maybe one man really is grasping a pillar, another a tree trunk, or hand fan, and another pushing on a wall.  No wonder their observations don't add up.  Suppose they insist on their observations adding up to something - then they may produce a forced "body of knowledge", something like astrology.

So what does a science finding its elephant look like?  There should be some convergence of observations when the blind men work together effectively, like more than once a man grasps something like a pillar.  Attempts to find relationships between observations.  Maybe 4 men are saying "this is like a pillar", and they can tell by listening they are close to each other, and they reach out until they grasp each others' hands, and get a sense of where each man is, and maybe all link hands to discover that the pillars are in a rough square.  Someone again says it's like a rope, and they wave their hands around until the one with the "rope" finds he's roughly equidistant from two of the "pillar" men.  And on and on.  Someone says "this is like a creek", but his voice is too far away, so the others say "That's something else, come back to where we are."  And as long as they stay close together, maybe holding hands, circling the object together, certain observations occur repetitively, and all the relations between the observations begin to add up to something.  Maybe someone bounces a basketball their way, one grasps it and says "something new!" but they soon realize it isn't part of the thing they're trying to understand.  It is "irrelevant data", or "noise" as in Nate Silver's The Signal and the Noise: Why So Many Predictions Fail - but Some Don't.

When observations add up and complement each other, and it becomes more and more clear which observations belong to the newly emerging object of study, and which do not, we can say there is a tractable domain.   Tractability is not absolute.  Until the 20th century, medicine was largely intractable.  We had only glimmerings of understanding here and there that could not be worked into any sort of whole.  Failure to admit this -- wishful thinking -- led to systems like that based on the "humours" (or 5 basic fluids supposed to account for the body's workings) which lead to inappropriate bleeding and purging, and sometimes even preventing elimination, all on the theory that too much or too little of some "humour" caused a given syndrome.

A tractable domain means one has a good sense of the thing that is under study - and this leads to techniques of study specific to the domain or object of study, unlikely to make sense in any other domain.   It might be invisible elephants, or equally invisible atoms, whose properties can only be known via more complex and roundabout ways than merely looking.  The idea that all scientific methodology can be summarized by one "method" is more often heard in disciplines that are trying hard to be scientific than in those which have gotten very clear about, and been shaped by, their subject matter.

Consensus that we are talking about the same thing (from different angles) is the sign that you may have found your elephant. In 17th century physics it was the large objects of the universe going around and around in patterns that Galileo, Kepler, and Newton finally made sense of and it lead to powerful general principals.  In the 18th century, various manifestations of electricity presented a mystery to be solved, once some of the phenomena proved to relate to others in certain patterns.  Lightning in the sky may somewhat resemble the sparks that jump from the glass globe that has been rubbed in a certain way, but are they really alike?  Benjamin Franklin is supposed to have answered this. In late 19th/early 20th century physics it was the structure of the atom (you can tell by now that a field might have more than one elephant, but it needs at least one).

Maybe it's just because of an argument I had a while back over global warming with a guy claiming methods cited to support it were not "the scientific method", and he described "the scientific method" as he learned it from his psychology professor some decades back ... but I really suspect it is a sign that a science has not yet gotten much traction when you hear so much about a (one size fits all) "scientific method".

Sometimes mistaken "knowledge" plagues humanity, and a radical new vision is required to prove tradition must be broken, and that a better understanding can be gained.  But the image of Galileo or Columbus or Pasteur standing alone is a kind of story that has itself become too much of a tradition - a story that our minds love to hear -- we are fooled into thinking that practically everything good had to come from such a stand.  We have an addiction to the idea of the individual rebel that is so prevalent that groups with quite opposite tendencies, such as Hollywood liberals and those who loathe such liberal politics are alike sunk in it up to their eyeballs.  We celebrate Steve Jobs and forget about Xerox PARC, a collaboration which generated the fundamental concepts behind the Apple computing model.  "Liberal" Hollywood gives us Dirty Harry, Jack Bauer, and dozens of other action heroes who act on their own, as well as heroic victims and lone whistle blowers by themselves against shadowy forces, and artists despised in their own lifetimes.

There really are many occasions for honoring such individuals, but our popular art and literature hardly recognizes anything else, and we tend to exaggerate their aloneness. Like Newton, had to stand on the shoulders of many others (not all giants).

Superheroes. which have gone from comic books for nerds to a main staple of Hollywood, seem to be the purest embodiment of our fascination with one great soul having to save the world with no help from anyone, and, of course they are the least realistic embodiment.  The right leaning press gives us  the lone gunslinger (in the supermarket yet) and heroic billionaires at risk of being tied up and paralyzed by the system.

Science still on occasion needs the unique visionary who find a new elephant, or find out that everybody else had the elephant upside down.  Sometimes they can't make themselves understood, and suffer frustration, but, at least in the hard sciences, it still takes a unique vision to win the greatest rewards, such as the the Nobel Prizes.  Scientific culture is such that if nearly everyone is mistaken, and one person can demonstrate this, they may be controversial for a while, but the best proof or demonstration tends to win in time -- due to a culture founded on the idea that the truth is the most important thing

But the majority of scientists are trying to get more and more detail on the same elephant, like the astronomers who spent their lives even before telescopes plotting where the star or planet is in the sky at such and such a longitude and latitude at a certain moment, who gave Kepler and Newton the masses of data they required.  Without them, most great leaps could not have happened.

Scientific consensus has been confused with group-think, which is far more likely to come from think tanks set up to serve a particular political agenda, or scientists who cater to tobacco or oil companies.  True scientific consensus comes from many scientists putting maps, table, graphs, observations and experiments together and after much wrangling coming to approximate agreement about what they add up to.  It is often something that just one of the scientists cannot confidently pronounce without the others, all looking at the problem from different angles.

What is A Machine? Natural Machines and Origins of Science

(Note: This essay is likely to evolve, but started as "What is a Machine?" on the "Ontological Comedian" blog)


The concept of machine pervades our culture, and has occupied an important place in philosophical debates for at least the last two or three centuries.

For example, it is often argued that living organisms, or the human mind, are "ultimately just machines". I.e. underlying all the organic, often amorphous complexity of the world we perceive, is a level at which ultra-miniscule machines function predictably. Electrons spinning around nuclei at an exact, measurable speed; light photons traveling always at a particular speed. At the heart of biological processes are DNA molecules whose properties can in theory be exactly deduced from the sequence of molecules of which they consist.
