A Conundrum(?) about Empirical Knowledge and Empirical Belief.

addenda 031819
In so far as a scientific statement speaks about reality, it must be falsifiable; and in so far as it is not falsifiable, it does not speak about reality.” -- Karl Popper

No amount of experimentation can ever prove me right; a single experiment can prove me wrong. -- Albert Einstein
BEGINNING:The Empirical Conundrum.
Original Assumption: Knowledge and Belief are not the same.
Belief may be a component of Knowledge, but Knowledge need not be a component of belief. Some beliefs are not knowledge.
Proposition A: Empirical Knowledge Claims are Defeasible (falsifiable), by virtue of their being empirical.
, i.e. defeasible means subject to withdrawal by virtue of possible (though maybe as yet unknown) countering evidence, CE. (See Three Human Dimensions of Conceptualization.)

Then,
Proposition B: Empirical Knowledge claims are, at best, Empirical beliefs.
So, it follows that
Proposition C: if something is at best an Empirical Belief. it is not Empirical Knowledge,
according to the Original Assumption.

Proposition C applies to anything that is claimed to be empirical evidence.

Thus Empirical Knowledge is not defeasible and consequently not empirical, gotten via the contrapositive of Proposition A.

Attempted Rebuttal.

But what is this CE? Is it Empirical Knowledge? If so, then by Proposition A, it is defeasible, ergo, merely Belief.

Thus, if counter-evidence CE is merely Empirical Belief; it is not really counter-evidence. Thus, Propositions B and C are gainsaid and consequently, Empirical Knowledge is, indeed, defeasible. (GO BACK TO BEGINNING.)

A Most Annoying (crucial?) Question: "How Do You Know That?"

updated 111220

He who knows nothing is closer to the truth than he whose mind is filled with falsehoods and errors. -- Thomas Jefferson
"How do you know that?" Unless we are teachers in a classroom, or students in a philosophy seminar, we tend to raise that question only when confronted with a statement we find unfamiliar or uncomfortable. Just posing the annoying question risks being taken as challenging the good sense or honesty of the claimant. And, as more and more people have come to realize, almost any old statement can, initially, at least, serve as a response to brush off the inquiry.

So it is that many us stumble through life sticking with the familiar and comfortable beliefs we've had passed down to us, even though, upon reflection, we know that what people believe, or not, is not a measure of truth or falsity. How many times throughout history have people been called to sacrifice themselves (or others) dearly for some Faith in an unexamined "Truth"? (What "truths" have been served by setting off bombs in civilian marketplaces and schools?)

Let's relax and consider. Suppose we wanted to know why the sun rises in the East and sets in the West. As we walk down the street we see coming toward us some familiar faces: three deeply educated men, Lorenz, Maurice and Curlius, believed by many to comprise the Wisdom of the Ages. We stop, greet them and ask, "Why is it that the sun rises in the East and sets in the West?"

They answer as follows:
Laurence, a scholar of ancient religions: 'Tis because Phoebus, the Sun, rises in his golden chariot in the East, drives across the sky to the West and then spends the night traveling underground to get back East to repeat the cycle."


Maurice, Ptolemaic scholar: Who believes that anymore? Actually, it is because the Earth, as center of the Universe, is circled by the Sun. What we call night is our period in shadow. The Sun's visible arc begins for us in the East and travels to our West.

Laurence interjects: Well, Maurice, I disbelieve your story. So there!

Curlius, erstwhile Copernican companion, declares: You may well believe your falsehoods, but the truth is that the Earth travels around the sun, spinning counterclockwise on an axis somewhat perpendicular to its orbit. So there!

Laurence and Maurice, both: Utter nonsense!

This interchange illustrates some principles we come to know at an early age, even though many fail to put them into practice in the direst of circumstances.
That some people believe something does not mean it is knowledge.

That some people disbelieve something does not mean it is not knowledge.

Our continuing controversies over evolution or global warming, illustrate these principles.

(However, were we to put the annoying question to our three sages, they, being deeply educated would likely be able to produce justifications for believing their respective claims to be true, as well as for rejecting counterclaims as untrue. So much for Plato's definition of Truth as justified, true* belief!)

But this goes way beyond the concerns of classrooms and philosophy seminars. What damaging actions might have been forestalled, what rash decisions reconsidered, what innocent bodies left unbroken, what promising lives saved, had the annoying question, "How do you know that?" been seriously considered at the appropriate times in the long, sad history of this planet?

Public “Science” Controversy: distrust is not the only issue.

edited 2/23/21
“We live in a society absolutely dependent on science and technology and yet have cleverly arranged things so that almost no one understands science and technology. That's a clear prescription for disaster.” -- Carl Sagan

No amount of experimentation can ever prove me right; a single experiment can prove me wrong. -- Albert Einstein

I would never die for my beliefs, because I might be wrong. -- Bertrand Russell

Need Understanding Promote Acceptance? For as brilliant a scientist (and advocate of Critical Thinking) as Carl Sagan was, he makes a common, and erroneous logical leap: he appears to imply that to understand something is necessarily either to condone or advocate it.

This is wrong. Understanding something (or someone) is not to concede it some kind of validity or authority. But should understanding a practice (or person) bring us to conceding, at least, a live-and-let-live attitude toward it?

Consider the Aztec practice of human sacrifice. Or the regimes of Hitler or Stalin. We pretty much know why they did what they did. We have a good idea what their supporting religious and cultural beliefs and practices were, and how they were carried out. Should we thus adopt a live-and-let-live attitude toward them? Certainly our understanding of what they were about need not move anyone to see their examples repeated.

”Science” Perceived as a Special Interest. We live in a Market Culture. Caveat Emptor, folks! It’s not hard to understand why many people -- not necessarily only uninformed or ignorant people -- are suspicious of pronouncements about, say, global warming, safe vaccinations, or gender differences correlating with intellectual inferiority in science. They consider the sources, motivation and social contexts of the claims or claimants. All’s fair in love, war, and marketing. (See Bestowing Trust.)


Anyone with a memory reaching back more than twenty-five years -- or some acquaintance with history -- can remember when “science” was invoked to justify slavery, frequent wide-spectrum use of antibiotics and promiscuous electric-shock therapy, as well as systematic X-ray exposure to treat teen-age acne. And, don’t forget, tobacco companies could always find a scientist to insist that there was no link between smoking and cancer. (See The 7 biggest problems facing science, according to 270 scientists.)

But “Science” corrected itself, did it not? Yes, so to speak. But generally, only in areas that did not upset entrenched cultural hierarchies. It took World War II to convince most Americans that women could learn to weld and to construct machines. That non-Whites, even Japanese, Native and African Americans could loyally defend a country where they had been treated with so very much less respect than citizens of European derivation. That not all, if some, human behavior was controlled by environmental reinforcement.

U.S. University presidents, even, were abashed to find out that common “grunts,” returning working-class GI’s, could actually use the GI Bill to acquire a profession. WWII Veterans on the GI Bill neither destroyed private higher education -- as predicted by James Conant -- nor did their presence turn universities into "vast hobo jungles" -- as Robert Maynard Hutchins warned they would.

The Elephant in the Room? Two Antagonistic Conceptions of Knowledge.

“Our knowledge can only be finite, while our ignorance must necessarily be infinite.” -- Karl Popper

In so far as a scientific statement speaks about reality, it must be falsifiable; and in so far as it is not falsifiable, it does not speak about reality.” -- Karl Popper

There is a deeper issue underlying the widespread skepticism about Science than suspicions about marketeering. It is that there are, roughly speaking, two competing concepts of knowledge embedded in our society. Many people, generally those with scientific training, or interest in scientific activity consider -- or at least give lip-service to the idea that -- scientific knowledge is an accumulation of hypotheses that are

a. tentative and correctible, (therefore, always possibly evanescent);
b. most persistently survivors of critical testing; and
c. cross-disciplinarily or experimentally mutually reinforcing.
d. Predictions are, at best, estimated with better than random probability.

This is the notion Einstein and Russell are alluding to in their quotes in the epigraph. I will refer this notion, albeit imprecise, as the notion of “Experimentalist Knowledge”. Any "Faith" one has in Experimentalist Knowledge is conditional upon its producing outcomes that someone values (in some "market"?), or at least, that one can hopefully predict (and, maybe, control -- barring certain kinds of complexity) through testing and adjustments in theory and procedure.

Within a professional context, Experimentalist Knowledge is not only given often precise expression, but carefully practiced, because any resultant publication must pass peer revue. Questioning can be quite intense and rigorous (and, to less prepared souls, annoying.} In the marketplace, as we will see below, something else happens.

A Competing Tradition. Eternalist Knowledge is a more ancient concept but still quite active today. It is given lip-service, at least, not only by adherents of certain religions, but also by many mathematicians, theoretical physicists, philosophers, mystics and "humanist" educators.

Eternal Truths are:

a. unchanging and eternal;
b. beyond being challengeable by “so-called tests”; and
c. often indifferent to other claimants to truth.
d. Predictions are considered to be either certainties, e.g. (logically?) derived from more basic Eternal Truths, or speculations of lesser concern.

Within a professional context which typically includes non-professionally prepared participants -- e.g. a laity --, there is at most a perfunctory "peer review" with a bias toward maintaining the authority of the professional over the layperson. Questioning, unless ritualized, is not encouraged.

So if adherents of Experimentalist Knowledge warn about global warming, those of Eternalist Knowledge might reply in dismissal, “Our Faith in X (or Y or Z) is our assurance that we will be exempt from such travail.”

Whether or not they are very devout adherents of eternal truths, many people’s ideas of science are as sophisticated as weather-forecasting TV permits. Snow, if predicted, often amounts to little. And yet, despite mathematical models and predictions, we get surprises. In the communities where Eternalist Knowledge dominates, lip-service is often reinforced by practices and rituals. But it, too, like Experimentalist Knowledge, can be transformed by the ethos of various markets.


An Important Caution. The reader ought not assume that what follows from the distinction Experimental or Eternalist is that either of the two traditions is being offered as "superior" to the other. In a disagreement it will all depend on what claims are made and which tradition is invoked. Nowadays a minor flesh wound is not treated with a prayer service. Nor is a geometric axiom invoked in a cry of mourning.

People who recognize certain items, e.g. holy scripture, foundational moral axioms, domains of discourse or procedure as "worthy" of pursuit are likely committed to justification by certain forms of Eternalist Knowledge. So also may be scientists who engage in debates about "Laws of Nature", or whether the Universe consists basically of "wave or particle"; or, whether individual rights ought to override "needs" for social stability. Or whether a mother's or her foetus' life should take precedence. Or, even, what criteria should be used, if any, to implement discriminatory treatment of populations, e.g. who gets a rare vaccine, or pardon for criminal behavior.

(The wisdom of recognizing the Experimentalist-Eternalist distiction seems to indicate that the much-vaunted pursuit of Artistic or Philosophical Authenticity, the degree to which a person’s actions are congruent with his or her beliefs, must take second-place to a modicum of hypocrisy, if only for survival purposes.)

Debating About “Science” in the Market: a slogan-fest.

The arc of the moral universe really is bending toward progress. -- Michael Shermer, The Moral Arc, (Henry Holt, 2015) précis of article appearing in Scientific American, Jan. 20, 2015

Professional interaction and market interactions are quite different, even among adherents of the same type, i.e. those of Experimentalist Knowledge, Empiricists, or those of Eternalist Knowledge, Eternalists. The epigraph of this section is certainly strange. For appearing in a generally Empiricist publication it looks suspiciously like an Eternalist statement.

Let's put some questions to Shermer. What is this "arc of the moral universe" in empirical terms? How does one determine the direction in which it bends? If one considers that 200,000,000+ people, mostly non-combatants, were killed in wars in the 20th century and that the slaughters continue into this 21st, where might this moral universe be situated?

Or is this article's appearance in Scientific American merely meant to get Eternalist adherents to buy a subscription?

Consider the punditry published in even scientific journals about Global Warming, or Vaccination, or Spanking, or anything purported to be of Public Concern. There the rhetoric begins to heat up: individuals are treated as though having melted together into uniform sampling groups or opinion-blocks, e.g. Scientists, Religionists, Believers, Atheists, Conservatives, Liberals. Reifications and hubris abound. False consensus likely rules the day.


Does knowledge of either kind even matter here? Or is this game best described as Fools Fooling Fools?

C.P. Snow in 1959 anticipated a scholarly schism into two basic cultures, the Scientific and the Literary. Has his prediction been visited not only upon Academia; but, with a vengeance, upon our national culture as a whole?

Cause & Effect: essential belief, misapprehension, moral hazard?

updated 071322
The brain is a construction of the brain. -- Nietzsche
There Must Be a Better Way! (The proctological principle?) I was waiting in a doctor’s office to arrange an examination, when a nurse answered a phone call. The irate voice on the other end of the line resounded throughout the small room: “I’m getting a colonoscopic exam tomorrow and I’m told I have to flush my system out by drinking a gallon of some insipid water concoction over the next twenty-four hours.” “That’s correct,” replied the nurse. “That’s absolutely ridiculous!” retorted the caller. “In this day and age there must be a better way to do it!” “No, sir. There is not,” responded the nurse.

A stream of expletives gushed from the telephone receiver. I thought to suggest to the nurse that she advise the patient to use a plumber’s snake instead of the prescribed water solution. But I kept my silence.

Practically Necessary Beliefs. Our way of life depends on a certain system of beliefs handed down through the centuries, although substantially modified in the process. Our notions of self-control, insanity, responsibility, criminality, and justice rest ultimately on the belief that some events relate to one another as cause and effect.

Daily we debate about who has done what; or, who can do what -- pretending all along that these “practical” questions have little to do with what “ivory-tower types” would call “philosophy.” In the debate we presume our investigations rest on a firm foundation: not merely the “belief,” but the “reality” of cause and effect. The operative train of thought here seems to ride on the Proctological Principle: if we (think we) need it, it must, in this day and age, be “a reality.”

Are Cause and Effect Illusions? Bertrand Russell recounts in his memoirs how, as a young man, he woke up in his bed one morning and came to a frightening understanding as to what David Hume meant by his theory of causation. All we ever observe, Hume had written, are correlations; regular sequences of event. Cause is our interpretation, our belief, more commonly, an assumption that normally observed regularities of precedence and propinquity will continue into the future.

Russell feared to step out of his bed onto the floor. It might, if Hume were right, suddenly open up beneath him, since there was nothing more than assumption to guarantee the persistence of its support. Thus, he would fall into an abyss of … nothingness (?).

(Russell’s reasoning here is somewhat inconsistent: If he could not trust that the floor, though sound and normal, would continue to support him, how could he come to any conclusion about what might happen next? Maybe he might float over the abyss!)

Being ultimately a pragmatist, as we all tend to be, Russell got past this fear and out of his bed and on with his life. Possibly he came to the realization that his bed, too, -- or the foundation of his house, or England in its entirety -- could just as likely open up to swallow him as he imagined the floor might.

Ultimately, perhaps, Russell, being a philosopher, might have come to concede (he did so, later) that there is more involved in identifying cause-and-effect relations than what our perceptions give us. Even today we warn our students, friends, associates, and acquaintances, perhaps, -- often futilely -- that mere “correlation” neither indicates nor denies “cause.” Little matter; if they are gamblers, day-traders, newspaper columnists, or political incumbents, they tend to ignore us.

Cause = Perceptions + Assumptions. Russell’s, and our, ability to act in this world rests heavily on structures of trust in generally unproven (and purely empirically unprovable) regularities of persistence. We construct edifices of trust with bricks of hope and desire cemented together with no more than the mortar of our assumptions. (See Varieties of Explanation & Cause.)

Immanuel Kant, some decades after Hume, presented a counter to Hume’s apparent empirical skepticism by denying that the human mind could go beyond experience, even such experience as augmented with scientific apparatus, to settle questions such as the “nature” of causation or objectivity. Our knowledge, Kant says, such as it is, is limited to phenomena.

Phenomena are constructed within the framework of human categories of understanding, which constitute the structure of the human mind, although interacting in someway with entities -- or entity -- of the extra-phenomenal world. Number, unity or plenty, says Kant, is a category of human understanding; not necessarily to be expected to parallel extra-phenomenal “reality.” (Check out the notion of quantum entanglement to appreciate how Kant's distinctions still retain relevance; although, he seems not to have considered how developing technologies and theories might interact to substantially expand human experience.)


It is amazing how many people in so many walks of life just hate this kind of theory: the theory that in culling out the true from the false, the wishful or delusional from the real, we ultimately invoke items of belief that themselves can only be judged, ad infinitum, by invoking other items of belief. (See Getting Down to Facts: can we avoid making assumptions?)

Is there a Bedrock of Knowledge? So what if claims of knowledge are always risky, resting on a potentially infinite chain of assumptions? Why the panic? Or more likely, the dismissive disdain? (Much more polite, if more condescending.)

I suppose it’s frightening. What? No absolute bedrock of The Known upon which to build our temples of Value, Prestige, Justice and Faith? Must everything be at risk? Can we, no matter how high our IQ or repute, how vast our wealth or influence, never be free from the risk of mistake?

Excepting formal linguistically constructed systems, i.e. knowledge by definition or stipulation, never, it would seem.

But does it really matter whether we occasionally stumble through life, rather than exhibiting perfection in all our decisions? Apparently to some people it does. Many who would reject the idea that knowledge may be essentially tentative are not inclined to even bother to present counter-argument or -evidence. Their basic concern, one might suspect, is more to preserve their incumbency in privileged positions; or, their right to importune others less empowered, i.e. to be in a condition of permanent moral hazard.

**Consider the similarities also in
Isaiah 45:7 (KJV) "I form the light, and create darkness: I make peace, and create evil: I the Lord do all these things."

And, also, the conversation between Faust and Mephistopheles (1335-1337 and 1345-1358 Original German edition, my translation -- EGR) wherein Faust's question as to who Mephisto is is answered "I am a part of that power that always pursues Evil yet always yields Good."

Faust counters, "How can you be a part of something when you present yourself to me as a whole?", Mephisto replies,"... Although (you) a human, from that a tiny world of fools, may consider yourself a whole, I am a part of a part that once was Everything, the Darkness that gave birth to Light."

What Can You Believe? Whom Can You Trust?

edited 1/14/19
"There's a sucker born every minute" -- a phrase often credited to P. T. Barnum (1810–1891), American showman
Should you believe a person who tells you that the moon landings were faked on a Hollywood production lot? Why or why not?

Can you trust anyone who tells you he talks with the dead? Why or why not?

Honesty and truth are not necessarily connected. Honest people may promote falsehoods, believing them to be true. Dishonest people may, on many an occasion, tell truths -- for various reasons, usually because they have no stake in it. Involved are two different dimensions of judgment, intention vs. facticity.

These are not particularly deep issues; but some careful thought may be needed to sort out those people we can trust or not, from the reliability of the information we get from them.

A whole lot depends on what they present as evidence. How might you evaluate it?

What is Superstition? Why Does It Matter?

edited 4/1/20
… a superstition is nothing other than a supposed natural correlation that is supported solely by convention and is unverified by controlled observation. --Stephen C. Pepper, Ethics, (1960) p. 55.
Is Pepper right? His attempt at defining a superstition seems to be an improvement over our everyday notion, which goes something like this:
If you and I both believe or disbelieve something, then it’s an example -- we assume -- of knowledge.
If I believe something you don’t, then that is an example of your ignorance.
But if I don’t believe something that you do, then that is an example of your superstition.
Nonetheless, there is less to Pepper’s definition than meets the eye; it raises several questions:
1. Who is doing the supposing? Doesn’t that matter?
2. How can we tell if the supposition is “supported solely by convention” ?
3. Need we verify everything “by controlled observation”?
Here are some beliefs we are not likely to dismiss as mere superstition, if superstition at all:
A. Ice feels cold.
B. The language you are reading this essay in is English.
C. What you see with your own eyes is not 100% illusion or hallucination.
Have you ever remarked, "I suppose that ice is cold"? Do you have to carry out a series of “controlled observations” to justify believing A or B or C above as something other than superstition?


If I have persuaded you that Pepper hasn't got it quite right, and if you still think it is an important matter to distinguish between knowledge and superstition (After all, which should we teach our children?), then see Questionable Assumptions in Social Decision Making

Living with False Assumptions

Never ASSUME, for when you ASSUME 

You make an ASS out of U and ME. 

-- Benny Hill
Like fat, sugar and other additives in our foods, the following “principles” are so deeply embedded in our culture that in most situations we unthinkingly fall back on them, although, under even casual consideration, we would find them far from certain. These principles are
The Principle of Command: To command is to control.
The Principle of Accepted Value: What we value, everyone should value.
The Principle of Objectivity: Facts are facts.
How do such principles control our thought processes?
