‘Material’ as *Alienans* in ‘Material Implication’

The topic of conditionals is ancient, not as ancient as Aristotle and logic itself, but damn near: hard thinking on this topic began with the Dialectical School which featured such worthies as Philo the   Logician and Diodorus Cronus, circa late 4th to mid-3rd centuries B.C. In nuce, those gentlemen had wrapped their minds around what much later came to be called material and strict implication, Philo around the former, Diodorus around the latter. The topic of conditionals is also deep and fascinating. But then no topic in philosophy lacks for fascination. The mansion of philosophy has countless rooms, each a labyrinth. Be sure to secure your thread of Ariadne before plunging on . . . .

The other day it occurred to me that 'material' in 'material implication' is best thought of as an alienans adjective. Normally, an FG is a G.  Thus a nagging wife is a wife, a female duck is a duck, cow's leather is leather, and a contingent truth is a truth. But if 'F' is alienans, then either an FG is not a G, or it does not follow from x's being an FG that x is a G. For example, your former wife is not your wife, your quondam lover is not your lover, a decoy duck is not a duck, artificial leather is not leather, negative growth is not growth, and a relative truth is not a truth. Is an apparent heart attack a heart attack? It may or may not be. One cannot infer from 'Jones had an apparent heart attack' to 'Jones had a heart attack.' So 'apparent' in 'apparent heart attack' is alienans.

Now if p materially implies q, does it follow that p implies q? Obviously not. I am breathing materially implies 7 + 5 = 12, but the first does not imply the second. Material implication is no more a kind or species of implication than former wives are a kind of wives, or artificial leather is a kind or species of leather. Just as 'artificial' shifts or alienates the sense of 'leather,' 'material' shifts or alienates the sense of 'implication.'

Material implication is rather a necessary condition any implication must satisfy if it is to be what it is, namely, a genuine implication. For all will agree that in no case does p imply q if p is true and q false. Thus material implication does capture something essential to every genuine implication. But if X is essential to Y, it does not follow that X is a kind of Y.

Once we appreciate that 'material' in 'material implication' is an alienans adjective, and that material implication is not a kind of implication, we are in a position to see that that the 'paradoxes' of   material implication are not paradoxes strictly speaking, but arise from foisting the ordinary sense of 'implication' upon 'material implication.'

Soul Food

People are generally aware of the importance of good nutrition, physical exercise and all things health-related. They understand that what they put into their bodies affects their physical health.  Underappreciated is a truth just as, if not more important: that what one puts into one's mind affects one's mental and spiritual health. The soul has its foods and its poisons just as the body does. This   simple truth, known for centuries, goes unheeded while liberals fall all over each other climbing aboard the various environmental and health bandwagons. 

Second-hand smoke the danger of which is negligible much exercises our leftist pals while the soul-destroying toxicity of the mass 'entertainment' media concerns them not at all.

Why are those so concerned with physical toxins so tolerant of cultural toxins? This is another example of what I call misplaced moral enthusiasm. You worry about global warming and sidestream smoke when you give no thought to the soul, its foods, and its poisons? You liberals are a strange breed of cat, crouching behind the First Amendment, quick to defend every form of cultural pollution under the rubric 'free speech.'

Levi Asher Writes Book on Ayn Rand

Levi Asher of Literary Kicks e-mails:
 
Your blog is just about my favorite philosophy blog on the web — not because I often agree with your political opinions (I don't) but because you write with clarity, humor and just the right amount of personal touch.  Salut!  I also write about philosophy on my blog Literary Kicks, and you may remember a cross-blog interchange between Litkicks and the Maverick Philosopher over the meaning of Buddhism late last year.
 
I'm writing you now to ask if I could send you a PDF or Kindle copy of my new book Why Ayn Rand Is Wrong (and Why It Matters), which is currently #21 on the Amazon Politics/Ideologies Kindle bestsellers list.  This book offers an unusual and original approach to Ayn Rand's ethical philosophy, and aims to present an alternative conception of practical ethics that cherishes individual freedom while allowing a greater regard for the important place of the collective soul in all our lives. Since you haven't paid much attention to Ayn Rand on your blog, I gather that she is not very present on your philosophical radar, but I hope you'll consider spending a few minutes checking out my short book regardless, because I think this book has wider value as an original approach to popular ethical philosophy.
 
Here is a brief explanation of why I wrote it.  Thanks for your time, and please let me know if I can send a PDF or Kindle version of "Why Ayn Rand is Wrong" for your consideration and/or review.  Have a great day!
Thanks for the kind words, Levi, and do send me the PDF file.  Actually, there has been a fair amount of discussion of Ayn Rand on this blog.  It is collected in the Ayn Rand category.  In early 2009 there was a heated debate here about Rand.  The posts with open comboxes drew over 200 comments.  There were numerous other comments that I deleted.  Rand attracts adolescents of all ages and they tend to be uncivilized.  I was doing a lot of deleting and blocking in early aught-nine.
 
But I agree with you: Rand's ideas ought to be discussed, not dismissed.

Eric Hoffer, Contentment, and the Paradox of Plenty

Eric Hoffer as quoted in James D. Koerner, Hoffer's America (Open Court, 1973), p. 25:

I need little to be contented. Two meals a day, tobacco, books that hold my interest, and a little writing each day. This to me is a full life.

And this after a full day at the San Francisco waterfront unloading ships.  And we're talking cheap tobacco smoked after a meal of Lipton soup and Vienna sausage in a humble apartment in a marginal part of town.  Hoffer, who had it tough indeed, had the wisdom to be satisfied with what he had. 

Call it the paradox of plenty: those who had to struggle in the face of adversity developed character and worth, while those with opportunities galore and an easy path became slackers and malcontents and 'revolutionaries.'   Adding to the paradox is that those who battled adversity learned gratitude while those who had it handed to them became ingrates.

Is College for Everyone?

When I was in the 7th grade my teacher told me I was 'college material,' the implication being that not everyone is.  She was right on both counts.  I was and not everyone is.  But times have changed, and pace Obama, change is not always for the better.  Part of the change for the worse is that the very phrase 'college material' has fallen into desuetude. 

The conceit that everyone can profit from a college education is of course foolish – which is perhaps why it is is so warmly embraced by liberals, those whose egalitarian instincts are rarely constrained by common sense.  It was foolish when college was affordable and it is multiply foolish now when it isn't.

I now hand off to 'Professor X' whose Atlantic piece, In the Basement of the Ivory Tower, is one of the best things I have read on this topic. 

Obama in Cloud Cuckoo Land

People say that Obama is intelligent.  I'll grant you that he is well-spoken: unlike Bush II he doesn't stumble over his words.  Trouble is, Obama's words are mainly  blather.  I fail to discern the substance of intelligence in them.  The man lives in a dream world. He's incoherent and irresponsible, an empty suit, a disaster.  The Anointed One has turned  out to be an emperor without clothes.  The audacity of hope has given way to the mendacity of empty hope and change rhetoric.

Part of the documentation for these assertions is provided by Victor Davis Hanson here.  Study it carefully.

Seneca on Books and the Library at Alexandria

De Tranquillitate Animi, IX, 4 (tr. Basore):

What is the use of having countless books and libraries, whose titles their owners can scarcely read through in a whole lifetime? The learner is not instructed, but burdened by the mass of them, and it is much better to surrender yourself to a few authors than to wander through many.

Well said. But Seneca continues with something that strikes some as dubious:

Forty thousand books were burned at Alexandria; let someone else praise this library as the most noble monument to the wealth of kings, as did Titus Livius, who says that it was the most distinguished achievement of the good taste and solicitude of kings. There was no "good taste" or "solicitude" about it, but only learned luxury — nay, not even "learned," since they had collected the books, not for the sake of learning, but to make a show, just as many who lack even a child's knowledge of letters use books, not as the tools of learning, but as decorations for the dining room.

It was only for learned luxury? The books were collected non in studium sed in spectaculum? And only forty thousand were burned? See here. Excerpt:

The actual number of books destroyed that Seneca gives is matter of some controversy that we will need to briefly address. In ancient manuscripts it is common for large numbers to be expressed as a dot placed above the numeral for each power of ten. Clearly in copying it is easy to make a mistake with the number of dots and errors by a factor of ten are frequent. That may have happened in the case of On the Tranquillity of the Mind. The manuscript from Monte Cassino actually reads 40,000 books but this is usually corrected to 400,000 by editors as other sources such as Orosius give this figure for the number of scrolls destroyed. I have not seen the manuscript, of course, so do not know if this way the number is expressed. However, even if it was given in words the difference between 40,000 and 400,000 is also pretty small. I propose therefore that the number given by Seneca, and indeed all other ancient sources, should be ruled as inadmissible as evidence because we cannot be sure of what it was originally.

On Comments

From the mail:

. . . I also wanted to thank you for hosting a blog where you disable comments half the time, and I mean that sincerely. I'm very tired of comment-culture, and it's nice to go to an interesting blog where the blogger seems focused on producing thoughtful and interesting things to read, rather than providing raw meat for comment-warriors to spar over.

Looking forward to more, as ever.

 

Never Bullshit! Mitt Romney on Non Sequiturs and the Null Set

Thinking about the mendacity of Obama, Schumer, and Kyl, I was put in mind of a post of mine dated 6 June 2007 from the old Powerblogs site in which I expose some bullshitting by Mitt Romney.  Here it is again.  If you want to be taken seriously by intelligent people, you must never use words you do not understand in an attempt to impress.  The only people you will impress will be fools.  By the way, some feel Romney is a viable Republican pick for 2012.  I wonder.  His being Mormon may not be a problem, but how remove the albatross of RomneyCare about his neck?  We have moved too far in the socialist direction.  We need to move back the other way, toward liberty and self-reliance, and I rather doubt that Romney is the one to lead us.

…………..

Governor Mitt Romney was asked the following question during last night's debate:

     We've lost 3,400 troops; civilian casualties are even higher, and
     the Iraqi government does not appear ready to provide for the
     security of its own country. Knowing everything you know right now,
     was it a mistake for us to invade Iraq?

Romney replied:

     Well, the question is kind of a non sequitur, if you will, and what
     I mean by that — or a null set. And that is that if you're saying
     let's turn back the clock, and Saddam Hussein had opened up his
     country to IAEA inspectors, and they'd come in and they'd found
     that there were no weapons of mass destruction, had Saddam Hussein,
     therefore, not violated United Nations resolutions, we wouldn't be
     in the conflict we're in. But he didn't do those things, and we
     knew what we knew at the point we made the decision to get in. I
     supported the president's decision based on what we knew at that
     time. I think we were underprepared and underplanned for what came
     after we knocked down Saddam Hussein.

Romney's response was quite good especially given the pressure he was under. But why did he spoil it by inserting unnecessary terminology that he obviously doesn't understand? It makes no sense to refer to a question as a non sequitur. A non sequitur is a proposition that abbreviates or 'telescopes' an invalid argument. For example, 'If the war in Iraq were serious, then we wouldn't be trying to fight it with an all-volunteer force.' That is a non sequitur in that the consequent of the conditional proposition does not follow from the antecedent. Non sequitur just means 'It does not follow.' But an interrogative form of words does not express a proposition. (Possible exception: rhetorical questions; but the question posed to Romney was not  rhetorical.) So to refer to a question as a non sequitur show a serious lack of understanding.

Romney should have replied simply as follows. 'It was not a mistake to invade Iraq since at the time the decision was made, that was the right course of action given what we knew.'

It is also nonsensical to refer to a question as "a null set." For one thing, there is only one null set. Talk of 'a' null set suggests that there are or could be several. More importantly, a question is not a
set, let alone a set with no members. "But isn't a question a set of words?" Well, there is for any question the set of words in which it is formulated, but that set is not identical to the question. But I
 won't go any further into this since, although it leads into fascinating question in metaphysics and the philosophy of language, it  leads away from the point I want to make.

 
"And what point would that be?" Never bullshit! You make yourself look stupid to people who really know. Never pretend to know what you don't know. Don't try to impress people with fancy jargon unless you really  know how to use it. Concern for truth dictates concern for precision in the use of language.

Call me a pedant if you like, but language matters!

Seeds of Hypocrisy

One who strives for the ideal but falls short is no hypocrite, but at a certain point the quantity and the quality of his fallings short must plant in his mind a seed of doubt as to whether he really avoids hypocrisy.  He preaches continence, say, but finds it hard to contain his thoughts, which are not particularly seminal, let alone his sap, which is.

Why Lie When You Have Good Arguments?

Last week I pointed out Senator Charles Schumer's blatant lie about Tea Partiers.  Apparently, Senator Jon Kyl has also lied and then gone on to justify his lie in a  manner most creative:

. . . Arizona senator Jon Kyl used his time on the Senate floor during a budget debate to claim that abortions make up "well over 90 percent of what Planned Parenthood does." When it was pointed out that, in fact, abortion funding constitutes about 3 percent of the organization's budget, Kyl shrugged it off. "It wasn't intended to be a factual statement," he said.

One question is why anyone would lie when they have he has decent arguments.  The use of tax dollars to fund abortion is morally wrong whatever one thinks of the morality of abortion itself.  It doesn't matter how many or how few tax dollars are used.  That's one argument.  A second is that funding outfits like Planned Parenthood is not among the essential functions of government, and that in a time of dire fiscal crisis, government must be pared back to its essential functions.  That's a second argument.  Properly exfoliated, they are powerful arguments.  They won't convince leftists, but then no conservative argument will.  But they will reinforce conservatives in their view and bring some fence-sitters over to our side.

Arguments appeal to our better nature, our rational, truth-seeking nature.

So what does Kyl do? He tells a lie thereby badly injuring his credibility.  Even if Kyl doesn't care about the truth, he ought to care about his credibility, and he must know that to be caught in a lie is to harm it.

So why lie when you have good arguments?

Perhaps it is like this.  "All's fair in love and war" and one of war's casualties is truth.  Politics has nothing to do with truth; it has everything to do with defeating your enemies and gaining or maintaining power.  Politics is about power, not truth.  Politics is war conducted by other means. (I call this the 'Converse Clausewitz principle.')

So perhaps when Schumer and Kyl et al. lie, they make a calculation:  the positive propaganda effect of the lie will offset the negative effect of being caught in a lie, and so lying is conducive to the end in view, namely, defeating the enemy.  Also to be considered is that when politicians  lie they are primarily addressing their constituencies many of the members of which do not care about truth either.  Proof of this is the crap that people forward via e-mail: scurrilous and unsourced allegations about Obama, Pelois and whoever.  When you point out to them that it is drivel, they are unfazed.  For again, it is about winning by any means, and truth doesn't come into it.

Mendacity pays.  Perhaps that is why politicians are so practiced in the arts of deception and prevarication.  They get away with their mendacity and we let them.  They don't care about truth because the people don't and they represent the people.  Maybe we get what we deserve.
