The Fragility of Knowledge

A recent addition to the collection of essays at “Einstein’s Errors” relies mainly on Christoph von Mettenheim’s Popper versus Einstein. One of Mettenheim’s key witnesses for the prosecution of Einstein’s special theory of relativity (STR) is Alfred Tarski, a Polish-born logician and mathematician. According to Mettenheim, Tarski showed

that all the axioms of geometry [upon which STR is built] are in fact nominalistic definitions, and therefore have nothing to do with truth, but only with expedience. [p. 86]

Later:

Tarski has demonstrated that logical and mathematical inferences can never yield an increase of empirical information because they are based on nominalistic definitions of the most simple terms of our language. We ourselves give them their meaning and cannot,therefore, get out of them anything but what we ourselves have put into them. They are tautological in the sense that any information contained in the conclusion must also have been contained in the premises. This is why logic and mathematics alone can never lead to scientific discoveries. [p. 100]

Mettenheim refers also to Alfred North Whitehead, a great English mathematician and philosopher who preceded Tarski. I am reading Whitehead’s Science and the Modern World thanks to my son, who recently wrote about it. I had heretofore only encountered the book in bits and snatches. I will have more to say about it in future posts. For now, I am content to quote this relevant passage, which presages Tarski’s theme and goes beyond it:

Thought is abstract; and the the intolerant use of abstractions is the major vice of the intellect. this vice is not wholly corrected by the recurrence to concrete experience. For after all, you need only attend to those aspects of your concrete experience which lie within some limited scheme. There are two methods for the purification of ideas. One of them is dispassionate observation by means of the bodily senses. But observation is selection. [p. 18]

More to come.

What’s Going On? A Stealth Revolution

UPDATED WITH A LIST OF RELATED READING

Senator Cory Booker (D-NJ) hints at the game plan:

I will be introducing a bill to remove Confederate statues from the US Capitol building. This is just one step. We have much work to do.

What work? Based on what I’ve seen since the Charleston church shooting in 2015, it’s a stealth revolution (e.g., this) piggy-backing on mass hysteria. Here’s the game plan:

Focus on racism — mainly against blacks, but also against Muslims and Latinos. (“Racism” covers a lot of ground these days.)

Thrown in sexism and gender bias (i.e., bias against gender-confused persons).

Pin it all on conservatives.

Watch as normally conservative politicians, business people, and voters swing left rather than look “mean” and put up a principled fight for conservative values. (Many of them can’t put up such a fight, anyway. Trump’s proper but poorly delivered refusal to pin all of the blame on neo-Nazis for the Charlottesville riot just added momentum to the left’s cause because he’s Trump and a “fascist” by definition.)

Watch as Democrats play the racism-sexism-gender card to retake the White House and Congress.

With the White House in the hands of a left-wing Democrat (is there any other kind now?) and an aggressive left-wing majority in Congress, freedom of speech, freedom of association, and property rights will become not-so-distant memories. “Affirmative action” will be enforced on an unprecedented scale of ferocity. The nation will become vulnerable to foreign enemies while billions of dollars are wasted on the hoax of catastrophic anthropogenic global warming and “social services” for the indolent. The economy, already buckling under the weight of statism, will teeter on the brink of collapse as the regulatory regime goes into high gear and entrepreneurship is all but extinguished by taxation and regulation.

All of that will be secured by courts dominated by left-wing judges — from here to eternity.

And most of the affluent white enablers dupes of the revolution will come to rue their actions. But they won’t be free to say so.

Thus will liberty — and prosperity — die in America.

Trump vs. Obama

Compare their standing with likely voters polled by Rasmussen Reports:


Derived from polling statistics for Obama and Trump published by Rasmussen Reports.

Each line represents the ratio of favorable to unfavorable views. Values above 1 mean that the favorables outweigh the unfavorables; values below 1 mean that the unfavorables outweigh the favorables. The light-blue and light-red lines track the 7-day averages of Obama and Trump’s overall ratings with likely voters. The dark-blue and dark-red lines track the 7-day averages of Obama and Trump’s ratings with likely voters who express strong approval or disapproval.

Trump’s comparative disadvantage seems to be shrinking. Here are ratios of the ratios plotted in the first graph:

Trump’s recent upswing relative to Obama reflects not only a slight softening of opinions about Trump’s presidency, but also the rapid decline in Obama’s popularity in the summer of 2009. (Caveat: The full effect of the events in Charlottesville on Trump’s standing may not be reflected in his numbers.)

Given the media’s incessant attacks on Trump, it seems unlikely that he’ll ever gain parity with Obama — whose negative ratings were based on his actual (and abysmal) performance.

Stay tuned.

A Baseball Note: The 2017 Astros vs. the 1951 Dodgers

If you were following baseball in 1951 (as I was), you’ll remember how that season’s Brooklyn Dodgers blew a big lead, wound up tied with the New York Giants at the end of the regular season, and lost a 3-game playoff to the Giants on Bobby Thomson’s “shot heard ’round the world” in the bottom of the 9th inning of the final playoff game.

On August 11, 1951, the Dodgers took a doubleheader from the Boston Braves and gained their largest lead over the Giants — 13 games. The Dodgers at that point had a W-L record of 70-36 (.660), and would top out at .667 two games later. But their W-L record for the rest of the regular season was only .522. So the Giants caught them and went on to win what is arguably the most dramatic playoff in the history of professional sports.

The 2017 Astros peaked earlier than the 1951 Dodgers, attaining a season-high W-L record of .682 on July 5, and leading the second-place team in the AL West by 18 games on July 28. The Astros’ lead has dropped to 12 games, and the team’s W-L record since the July 5 peak is only .438.

The Los Angeles Angels might be this year’s version of the 1951 Giants. The Angels have come from 19 games behind the Astros on July 28, to trail by 12. In that span, the Angels have gone 11-4 (.733).

Hold onto your hats.

The “Public Goods” Myth

The argument for the provision of public goods by the state goes like this:

People will free ride on a public good like a clean atmosphere because they can benefit from it without contributing to it. Mimi will enjoy more breathable air when others switch to a Prius even if she doesn’t drive one herself. So the state is justified as a means of forcing people like Mimi to contribute: for instance, by creating laws that penalize pollution….

Standard models predict that public goods will be underprovided because of free riding. Public goods are non-excludable, meaning that you cannot be excluded from enjoying them even if you didn’t contribute to them. Public goods are also non-rivalrous, meaning that my enjoyment of the good doesn’t subtract from yours. Here’s an example. A storm threatens to flood the river, a flood that would destroy your town. If the townspeople join together to build a levee with sandbags, the town will be spared. However, your individual contribution won’t make or break the effort. The levee is a public good. If it prevents the flood, your house will be saved whether or not you helped stack the sandbags. And the levee will protect the entire town, so protecting your house doesn’t detract from the protection afforded to other houses.

It’s typically assumed that people won’t voluntarily contribute to public goods like the levee. Your individual contribution is inconsequential, and if the levee does somehow get provided, you enjoy its protection whether or not you helped. You get the benefit without paying the costs. So the self-interested choice is to watch Netflix on your couch while your neighbors hurt their backs lugging sandbags around. The problem is, your neighbors have the exact same incentive to stay home— if enough others contribute to the levee, they’ll enjoy the benefits whether or not they contributed themselves. Consequently, no one has an incentive to contribute to the levee. As a result of this free-rider problem, the town will flood even though the flood is bad for everyone. [Christopher Freiman, Unequivocal Justice, 2017]

The idea is that private entities won’t provide certain things because there will be too many free riders. And yet, people do buy Priuses and similar cars, and do volunteer in emergencies, and do commit myriad acts of kindness and generosity without compensation (other than psychic). These contrary and readily observable facts should be enough to discredit public-goods theory. But I shall continue with a critical look at key terms and assumptions.

What is a public good? It’s a good that’s “underprovided”. What does that mean? It means that someone who believes that a certain good should be provided in a certain quantity at a certain price is dissatisfied with the actual quantity and/or price at which the good is provided (or not provided).

Who is that someone? Whoever happens to believe that a certain good should be provided at a certain price. Or, more likely, that it should be provided “free” by government. There are many advocates of universal health care, for example, who are certain that health care is underprovided, and that it should be made available freely to anyone who “needs” it. They are either ignorant of the track record of socialized medicine in Canada and Britain, or are among the many (usually leftists) who prefer hope to experience.

What is a free rider, and why is it bad to be a free rider? A free rider is someone who benefits from the provision and use of goods for which he (the free rider) doesn’t pay. There are free riders all around us, all the time. Any product, service, or activity that yields positive externalities is a boon to many persons who don’t buy the product or service, or engage in the activity. (Follow the link in the preceding sentence for a discussion and examples of positive externalities.) But people do buy products and services that yield positive externalities, and companies do stay in business by provide such products and services.

In sum, “free rider” is a scare term invoked for the purpose of justifying government-provided public goods. Why government-provided? Because that way the goods will be “free” to many users of them, and “the rich” will be taxed to provide the goods, of course. (“Free” is an illusion. See this.)

Health care — which people long paid for out of their own pockets or which was supported by voluntary charity — is demonstrably not a public good. If anything, the more that government has come to dominate the provision of health care (including its provision through insurance), the more costly it has become. The rising cost has served to justify greater government involvement in health care, which has further driven up the cost, etc., etc., etc. That’s what happens when government provides a so-called public good.

What about defense? As I say here,

given the present arrangement of the tax burden, those who have the most to gain from defense and justice (classic examples of “public goods”) already support a lot of free riders and “cheap riders.” Given the value of defense and justice to the orderly operation of the economy, it is likely that affluent Americans and large corporations — if they weren’t already heavily taxed — would willingly form syndicates to provide defense and justice. Most of them, after all, are willing to buy private security services, despite the taxes they already pay….

… It may nevertheless be desirable to have a state monopoly on police and justice — but only on police and justice, and only because the alternatives are a private monopoly of force, on the one hand, or a clash of warlords, on the other hand.

The environment? See this and this. Global warming? See this, and follow the links therein.

All in all, the price of “free” government goods is extremely high; government taketh away far more than it giveth. With a minimal government restricted to the defense of citizens against force and fraud there would be far fewer people in need of “public goods” and far, far more private charity available to those few who need it.

The Invalid “Viability” Argument for Abortion

Bill Vallicella (Maverick Philosopher) summarizes Elizabeth Harman’s argument for abortion:

1) “Among early fetuses there are two very different kinds of beings . . . .”

2) One kind of early fetus has “moral status.”

3) The other kind of early fetus does not have “moral status.”

4) The fetuses possessing moral status have it in virtue of their futures, in virtue of the fact that they are the beginning stages of future persons.

5) The fetuses lacking moral status lack it in virtue of their not having futures, in virtue of their not being the beginning stages of future persons.

Therefore

6) If a fetus is prevented from having a future, either by miscarriage or abortion, then the fetus does not have moral status at the time of its miscarriage or abortion. “That’s something that doesn’t have a future as a person and it doesn’t have moral status.” (From 5)

7) If a fetus lacks moral status, then aborting it is not morally impermissible.

Therefore

8) ” . . . there is nothing morally bad about early abortion.”

Vallicella then refutes the argument:

She is maintaining in effect that the moral status of a biological individual depends on how long it lasts. So the early fetus that developed into Elizabeth Harman has moral status at every time in its development, while an aborted early fetus has moral status at no time in its development.

This issues in the absurd consequence that one can morally justify an abortion just by having one. For if you kill your fetus (or have your fetus killed), then you guarantee that it has no future. If it has no future, then it has no moral status. And if it has no moral status, then killing it is not morally impermissible, and is therefore morally justified.

In sum, and with all due Maverickian pithiness: Moral status cannot be contingent upon longevity.

Harman’s argument is essentially the “viability” argument, which I have summarized and refuted several times. This is from “Crimes Against Humanity“:

The argument that a fetus is “inviable” — and therefore somehow undeserving of life — until it reaches a certain stage of development is a circular argument designed to favor abortion. A fetus (except in the case of a natural miscarriage) is viable from the moment of conception until birth as long as it is not aborted. It is abortion that makes a fetus inviable. Abortion therefore cannot be excused on the basis of presumed inviability.

(Read the whole thing.)

Fleshing it out:

There is an argument that a fetus should not be aborted (executed) after it becomes viable and therefore capable of surviving outside the womb and attaining “full personhood”.

This implies that it is wrong to prevent a fetus from attaining “full personhood” if it is capable of doing so.

All fetuses are potentially viable, though some fetuses may expire by miscarriage (or death in the womb).

Except in those unpredictable and unusual cases, abortion prevents a fetus from attaining viability.

Executing a fetus before it attains viability therefore presumably prevents it from attaining viability and (probably) “full personhood”.

It is therefore wrong to execute a fetus before it attains viability.

It seems that Vallicella and I see it the same way.

After demolishing Harman’s argument, Vallicella asks this (his boldface): “Is it ever morally right and reasonable to question or impugn motives or character in a debate?” Having refuted Harman’s argument on its own merits (or lack thereof) Vallicella answers his question with a “yes”, and continues:

I have a theory about what really drives the innumerable bad pro-abortion/pro-choice arguments abroad in this decadent culture, but I leave that theory for later. Here I pose the bolded question quite generally and apart from the abortion question.

I have a theory, too, which you will find in “Leftism As Crypto-Fascism: The Google Paradigm” and “Leftism“. It boils down the this: a need for control (authoritarianism), born of neuroticism and (sometimes) psychopathy.

In this case (as in many) the need for control exhibits itself as an urge to overturn civilizing social norms. (It’s the adolescent rebellion syndrome writ large.) The targeted norms vary with time, which is why the left’s agenda is malleable and guided by elite opinion. And leftists obtain a degree of relief from their neuroticism by attaching themselves to the ideology and “belonging” to the “cause” that is represented in the agenda du jour.

Thus leftism is an attachment to a superficial ideology that can be expressed in slogans (e.g., reproductive rights, equality), not a set of deep principles (e.g., socially evolved and tested norms guide behavior in constructive directions). The “viability” argument is circular because it stands (and falls) on neurotic feelings instead of deep principles.

Leftism as Crypto-Fascism: The Google Paradigm

NOTE TO READERS: I WILL CONTINUE TO UPDATE THE RELATED-READING LIST AS NEW, RELEVANT PIECES COME TO MY ATTENTION. MOST RECENTLY UPDATED ON 08/20/17 AT 2219 CT.

Google is a private company. I strongly support the right of private employers to fire anyone at any time for any reason. I am not here to condemn Google for having fired James Damore, the author of the now-notorious 10-page memo about Google’s ideological echo chamber.

The point of the memo, for those few of you who haven’t been paying attention, was the bias inherent in Google’s diversity policies, which ignore some basic (and well-known) facts about differences in men’s and women’s brains, bodies, and interests. Google fired Damore for “perpetuating stereotypes”, when it is Google which perpetuates anti-factual stereotypes.

I am writing about Google’s firing of Damore for daring to speak the truth because it is of a piece with the left’s political modus operandi:

  • Fixate on an objective, regardless of its lack of feasibility (e.g. proportional representation of various demographic groups — but not Asians or Jews — in STEM fields), lack of validity (e.g., the demonstrated inaccuracy of climate models that lean heavily on the effects of atmospheric CO2); or consequences (e.g., high failure rates among under-qualified “minorities”, lower standards that affect the quality of output and even endanger lives, the futile use of expensive “renewable” energy sources in place of carbon-based fuels).
  • Insist that attainment of the objective will advance liberty, equality, fraternity, or prosperity.
  • Demand punishment for those who question the objective, thereby suppressing liberty; fostering false equality; engendering resentments that undermine fraternity; and diminishing prosperity.

What happened to James Damore is what happens where leftists control the machinery of the state. (Be mindful that Hitler was a leftist, as I explain and document in “Leftism“.) I turn to Jean-François Revel’s Last Exit to Utopia: The Survival of Socialism in a Post-Soviet Era, with the proviso that his references to communism and socialism apply equally to leftism generally, whether it is called progressivism, liberalism, or liberal democracy:

[T]he abominations of actual socialism are characterized as deviations, or treasonous perversions of “true” Communism….

But this account of redemption through good intentions is undermined by an impartial and, above all, comprehensive exploration of socialist literature. Already among the most authentic sources of socialist thought, among the earliest doctrinarians, are found justifications for ethnic cleansing and genocide, along with the totalitarian state, all of which were held up as legitimate and even necessary weapons for the success and preservation of the revolution….

What all totalitarian regimes have in common is that they are “ideocracies”: dictatorships of ideas…. [T]he rulers, convinced that they possess the absolute truth and are guiding the course of history for all humanity, believe they have the right to destroy dissidents (real or potential), races, classes, professional or cultural categories — anyone and everyone they see as obstacles, or capable one day of being obstacles, to the supreme design….

… [Ideocracy] strives to suppress — and it must in order to survive — all thinking that is opposed to or outside the official party line, not only in politics and economics, but in every domain: philosophy, arts and literature, and even science.[pp. 94-100, passim]

The left’s supreme design includes the suppression of straight, white males; the elevation of females, blacks, Hispanics, other persons of color (but not Asians), and gender-confused persons, regardless of their inherent or actual abilities; the suppression of statements by anyone who questions the foregoing orthodoxies; the extinction of property and associative rights; and dirigisme on a scale that would be the envy of Hitler, Stalin, and Mao — despite its demonstrably destructive effects.

Trans Man Gives Birth, Shares Beautiful Story Of His Family

“He” stopped being an imaginary man long enough to have sex with a real man and conceive and bear a child. But the idiotarian left-wing press insists that a “man” gave birth.

The sun was shining on the sea,
Shining with all his might:
He did his very best to make
The billows smooth and bright–
And this was odd, because it was
The middle of the night….

Of cabbages — and kings –
And why the sea is boiling hot –

Why ‘s Matters

I have added this to my page, “Writing: A Guide“, as section IV.B.4.

Most newspapers and magazines follow the convention of forming the possessive of a word ending in “s” by putting an apostrophe after the “s”; for example:

Dallas’ (for Dallas’s)

Texas’ (for Texas’s)

Jesus’ (for Jesus’s)

This may work on a page or screen, but it can cause ambiguity if carried over into speech*. (Warning: I am about to take liberties with the name of Jesus and the New Testament, about which I will write as if it were a contemporary document. Read no further if you are easily offended.)

What sounds like “Jesus walks on water” could mean just what it sounds like: a statement about a feat of which Jesus is capable or is performing. But if Jesus walks on the water more than once, it could refer to his plural perambulations: “Jesus’ walks on water”**, as it would appear in a newspaper.

The simplest and best way to avoid the ambiguity is to insist on “Jesus’s walks on water”** for the possessive case, and to inculcate the practice of saying it as it reads. How else can the ambiguity be avoided, in the likely event that the foregoing advice will be ignored?

If what is meant is “Jesus walks on water”, one could say “Jesus can [is able to] walk on water” or “Jesus is walking on water”, according to the situation.

If what is meant is that Jesus walks on water more than once, “Jesus’s walks on water” is unambiguous (assuming, of course, that one’s listeners have an inkling about the standard formation of a singular possessive). There’s no need to work around it, as there is in the non-possessive case. But if you insist on avoiding the ‘s formation, you can write or say “the water-walks of Jesus”.

I now take it to the next level.

What if there’s more than one Jesus who walks on water? Well, if they all can walk on water and the idea is to say so, it’s “The Jesuses walk on water”. And if they all walk on water and the idea is to refer to those outings as the outings of them all, it’s “The water-walks of the Jesuses”.

Why? Because the standard formation of the plural possessive of Jesus is Jesuses’. Jesusues’s would be too hard to say or comprehend. But Jesuses’ sounds the same as Jesuses, and must therefore be avoided in speech, and in writing intended to be read aloud. Thus “the water walks of the Jesuses” instead of “the Jesuses’ walks on water”, which is ambiguous to a listener.
__________
* A good writer will think about the effect of his writing if it is read aloud.

** “Jesus’ walks on water” and “Jesus’s walks on water” misuse the possessive case, though it’s a standard kind misuse that is too deeply entrenched to be eradicated. Strictly speaking, Jesus doesn’t own walks on water, he does them. The alternative construction, “the water-walks of Jesus”, is better; “the water-walks by Jesus” is best.
