Many of us questioned President Txxxx’s coronavirus-ridden return to the White House, but now that he’s threatened to travel to Miami, reverted to spreading months-old disinformation about COVID-19, and sent the economy into a nosedive, it seems clear the man’s judgement is as sound as ever.

  • Within moments of arriving home, a highly-medicated Dxxxx Txxxx horrified doctors (and also, everyone) by dramatically removing his mask and releasing a bizarre propaganda video that asserted he contracted coronavirus as an act of…leadership. Today Txxxx proved how much he’s learned from his firsthand leadership experience by spreading the same false comparison between coronavirus and influenza he first promoted 210,000 deaths ago. Social media companies censored those posts, leading Txxxx to cryptically call for the destruction of the internet. He’s back, baby!
  • Not content to shed coronavirus around the hard-hit, poorly-ventilated West Wing, Dxxxx Txxxx has announced his intention to take this infectious show on the road. Txxxx’s lying doctor Sean Conley put out a statement that the president, who was visibly gasping for air upon his return to the White House on Monday, today “reports no symptoms,” and the miraculously recovered 74-year-old tweeted that he’s “looking forward to the debate on the evening of Thursday, October 15th in Miami. It will be great!” That townhall-style debate would be just two weeks after Txxxx (purportedly) began experiencing symptoms, and it is beyond insane for him to consider attending it in person.
  • On Monday Conley suggested that Txxxx’s tweets served as a useful gauge of his mental fitness. We would be interested to know what the good doctor thinks about these ones, in which President Deals shut down all hopes of further coronavirus stimulus until after the election and immediately tanked the stock market. Incidentally, here’s a new poll that found 74 percent of voters think the Senate should prioritize coronavirus relief over confirming Amy Coney Barrett. More Coronavirus, Worse Economy: It’s a bold closing argument from Team Txxxx.

Meanwhile, as more people in the White House’s orbit fall ill, the administration has worked systematically to make sure we never learn when Txxxx last tested negative, or how many people contracted the virus from him or people at his superspreading events.

  • Stephen Miller has it. Nearly all of the Joint Chiefs of Staff are in quarantine after a Coast Guard admiral tested positive. Txxxx’s Coast Guard aide Jayna McCarron has coronavirus, as does one of his active-duty military valets and a third press office aideNew York Times reporter Michael Shear said his wife has now tested positive: “The collateral damage is going to be pretty significant, I think.” White House employees are rightly scared and angry; one source told Axios, “It’s insane that he would return to the White House and jeopardize his staff’s health when we are still learning of new cases among senior staff. This place is a cesspool.”
  • Txxxx’s recklessness and refusal to conduct contact tracing have consequences beyond the White House grounds. Washington, DC, reported 105 new coronavirus cases on Monday, the city’s highest one-day spike since June. That spike may not be a function of the Rose Garden Misadventure alone. John Hagee, a megachurch pastor and Txxxx advisor, has tested positive; he wasn’t present at the Amy Coney Barrett nomination event, but he did attend a September 15 White House event along with hundreds of people who were largely flouting safety measures. 

Our new reality is almost too surreal to fathom: The president and his allies are not only neglecting their responsibility to bring the pandemic under control, they’re now actively and knowingly spreading a deadly virus themselves. What a good time to don the hazmat suit of democracy and escort them out.

Philosophy Talk

A philosophy professor named Tim Sommers and I had an exchange at Three Quarks Daily about the Liar’s Paradox (the president wasn’t mentioned):

TS: There’s something wrong with the sentence, “This sentence is false.” Is it true or false? Well, if it’s true, then it’s false. But then if it’s false, it’s true. And so on. This is the simplest, most straightforward version of the “Liar’s Paradox”. It’s at least two thousand five hundred years old and well-known enough that you can buy the t-shirt on Amazon.com.

this-sentence-is-false

I’ve been thinking about the “Liar’s Paradox” lately, because I’m teaching an “Introduction to Philosophy” class on paradoxes (and writing a book) called “Life’s a Puzzle: Philosophy’s Greatest Paradoxes, Thought-Experiments, Counter-Intuitive Arguments, and Counter-Examples from AI to Zeno”. It starts with the “Liar’s Paradox” because it’s one of the oldest and most well-known, but also simplest and most daunting, of philosophical paradoxes. Some people think that while “puzzle” cases in philosophy are fun and showy, they are not where the real action is. I think every real philosophical puzzle is a window onto a mystery. And proposed solutions to that mystery are samples of the variety and possibilities of philosophy.

So, let’s start with this. Why is it called the “Liar’s Paradox”? Let’s go to the Christian Bible for that one, specifically, “St. Paul’s Letter to Titus” (Ch. 1, verses 12-14)

“They must be silenced, because they are disrupting whole households by teaching things they ought not to teach – and that for the sake of filthy lucre.12 One of Crete’s own prophets has said it: ‘Cretans are always liars, evil brutes, lazy gluttons.’13 This statement is true.14”

Verse 12 has philosophers dead to rights. We are disrupting whole households, teaching things we ought not to teach and – speaking for myself at least – it’s all about the filthy lucre (hence, the book). But verse 13 is what we want here. It has “Cretan’s own prophet” saying “Cretans are always liars.” Now, if that just means that all Cretans lie a lot, but not all the time, there’s no problem. But if it means that Cretans are always lying whenever they speak, given that this is asserted by a Cretan (read: liar), we have a paradox. This then is the primordial, liar’s version of the “Liar’s Paradox”. If that’s unclear you can simplify the liar’s version down to: “I am lying right now.”

By the way, “Crete’s own prophet” was “Epimenides of Crete”. Crete is the largest of the Greek islands, only 99 miles from the mainland, but (at that time) culturally distinct. It was the home of the Minoans. You might think you’ve never heard of the Minoans, but you have. They built a very famous labyrinth . . . 

What should we say about, “This sentence is false”? What if we said not every sentence has to be true or false and leave it at that? But “This sentence is not true” works just as well. Or rather works just as paradoxically. It’s true, if it’s not true. If it’s not true, it’s true. Even if we say not every sentence has to be true or false, we can’t have sentences that are both true and not true. That’s a straight-up contradiction. . . .

There’s . . . something called the Prior solution to the “Liar’s Paradox”, not because it’s prior to anything, but just because [it was formulated by] Arthur Prior. Prior says every sentence already implicitly implies its own truth. So, “This is fun”, really says “This sentence is true and this is fun.” Apply that to “This sentence is false” and you get “This sentence is true and this sentence is false”, which asserts a contradiction and so is just false now and not paradoxical. Voila! Problem solved.

Except, did you ever see the episode of “Rick and Morty” where Morty said, “What Rick just said is false”, and Rick said, “What Morty just said is true”? That’s the two-sentence version of the “Liar’s Paradox”. . . . Prior’s solution can’t help us here. (1) This sentence is true and the next sentence is false. (2) This sentence is true and the previous sentence is true. The paradox does not go away.

Maybe, what’s wrong with “This sentence is false” is that it’s self-referential. But, in general, it’s not a problem if a sentence is self-referential. Consider, “This sentence is six words long”. That’s just true. No problem. Or “This sentence is seven words long”. That’s just false. No problem. But “This sentence is false” is not just self-referential, it self-referentially assigns itself a truth value. So, let’s take a step back.

You have to admit, our ordinary, natural language is a mess. It’s imprecise and ambiguous and, most importantly, as any computer programmer will tell you, natural languages are over-flexible. They allow sentences to do things like self-referentially assign their own truth value. Computer languages can be thought of as artificial languages that replace natural languages in some contexts. Some universities now have departments of “logic and computation” that are no longer part of the philosophy department. This kind of thing happens all the time historically, by the way –  some part of philosophy morphs into a science. Four hundred years ago physics was “natural philosophy” and now they expect their own offices.

Anyway, in such an artificial language you might think there should be a kind of hierarchy of types of sentences. So, in computing, or in [the philosopher Alfred] Tarski’s logic, sentences can only assign truth values to sentences that are lower in the hierarchy. They are forbidden to assign truth-value to themselves or any of the sentences that outrank them.

“This sentence is false” is just nonsense, then, because it violates this rule. On this way of looking at it, the “Liar’s’ Paradox” is evidence that you need to enforce such a rule and/or develop an artificial language – or you get insoluble paradoxes.

So, how can we resolve the “Liar’s Paradox”. Beats me. I am hoping you will leave the solution in the comments section so I can go tell my class.

LF (me): I wonder what it would mean to “resolve” the Liar’s Paradox? Regarding the simple case, “this sentence is false”, would we have to show why it’s actually a regular true or false statement, or that it’s meaningless or vague or ungrammatical? There are lots of ways language can be used poorly. For example, some statements are rude. “This sentence is false” is paradoxical and not paradoxical in a good way if you’re having a normal conversation. If you’re teaching a course and want to discuss the issues the sentence raises about language, it’s paradoxical in an excellent way. But, in general, we don’t have to resolve a paradox like “this sentence is false”. We just have to avoid talking paradoxically (or rudely, falsely, ungrammatically, etc.), unless there’s a special reason to do otherwise.

TS: Thanks for the comment. I get what you are saying, I think. But still…what, if anything, is wrong with “This sentence is false”? It doesn’t appear to be, as you say, “meaningless or vague or ungrammatical” or even “rude”. Calling it “paradoxical” is just giving it a name. So, what would a resolution look like? Here are my thoughts on what might qualify. It’s true. Appearances aside, it’s just false. It’s ill-formed logically or as a speech-act. It’s meaningless, because… My hunch is that self-referentially assigning its own truth value violates some kind of “rule”, but I would like to see what that rule is better characterized – because I think it would be informative.  

[LF]: I will try to clarify. Presumably, to resolve a paradox means to show that it isn’t paradoxical. To resolve a problem is to make it go away, to no longer be problematic. Yet “This sentence is false” is clearly paradoxical, so it can’t be resolved or addressed in that way.

The next question is why is “this sentence is false” paradoxical? It’s paradoxical because it gives with one hand and takes away with the other. In ordinary, practical terms, declarative sentences are supposed to say something that’s true, yet “this sentence is false” simultaneously suggests that it’s not true. If the statement is meant to convey accurate information, it fails. It’s paradoxical. If it’s meant as entertainment, however, or as an example in a philosophy course, the fact that it’s paradoxical isn’t a problem; it’s a perfectly fine way to speak.

It’s the same situation with the two-sentence version of the paradox (“the next sentence is false”; “the previous sentence is true”). In practical terms, uttering these two declarative sentences suggests that each sentence is both true and not true (the principal difference being that each sentence refers to the other, and thereby indirectly to itself, not directly to itself, as in the one-sentence case). It’s another unresolvable paradox, a case in which language is being used poorly, if it’s meant in the usual way, to convey accurate information when uttering declarative sentences. The two-sentence case isn’t ungrammatical or meaningless in the usual sense, or rude or vague, other ways in which language can be spoken inappropriately unless there are overriding reasons to speak in those ways, for dramatic effect, for example.

I don’t think there’s a rule against “self-referentially assigning [a sentence’s] own truth value”. For example, everything I’m saying in this paragraph, including this sentence, is true. The relevant rule is “don’t make a declaration and indicate that it’s not true, unless you have a good reason for being paradoxical or ironic”. In similar fashion, “don’t tell somebody to do something and not do it, unless you have a good reason for contradicting yourself and don’t want it to be done” and “don’t ask somebody a question if you don’t want an answer, unless it’s a rhetorical question”. There are ordinary ways to speak that work well. Don’t mess with the formula unless you have a good reason to. I think that’s as deep as we need to go.

(Note: “Don’t mess with the formula” are the immortal words of Mike Love, addressed to Brian Wilson when things began to get strange around 1966.)

Unquote. (Prof. Sommers hadn’t responded to my response last time I looked.)

One other thought. I’m enjoying my news vacation during these troubled and troubling times, even though news leaks through. One of the results of avoiding the news is that you’re living in a different context. It occurred to me that, if I ran across the phrase “Fump Truck” during a really thorough news vacation (or if FBI Director James Comey had followed the rules and kept his mouth shut in 2016), I’d probably think it was a variation on “Dump Truck”. It wouldn’t suggest an entirely different phrase (similar to, but not “Dump Trump”).

It Was Reckless Endangerment or Worse

At the Rose Garden event last Saturday when they introduced the Republican nominee to the Supreme Court:

Guests mingled, hugged and kissed on the cheek, most without wearing masks. An indoor reception followed the outdoor ceremony.

Seven days later, at least eight people who attended the ceremony have tested positive for the coronavirus, including the president. Several more of the president’s closest aides and advisers have also tested positive.

Then, our president got to work, spreading the joy:

EjavL0-WoAAdOxl

Of course, we’re only heard about some of the famous people who got the virus in the Rose Garden, at the White House, on Air Force One, at the rally or the fundraisers, not the common folk who rubbed shoulders with the rich and famous, or provided security, or served the drinks.

We knew he was a heartless prick who only cares about himself, but I mean, wow.

Postscript:  The White House doctor (i.e. public relations representative) has now “clarified” the timeline, explaining that when he said “72 hours” he meant “day three”, not “three days ago” (?). So it was actually Thursday night, after all the traveling about, when the president knew he had the virus, not Wednesday morning. Of course, everyone who speaks for the president can be trusted to deliver the unvarnished truth, so there’s nothing to see here. Obviously.

Perhaps the Commission on Presidential “Debates” Wants To Hear From You

We watched two episodes of Fargo‘s very disappointing new season instead. We already know who these candidates are. We already know that the president is unwilling and/or unable to carry on a civil conversation. The Commission would do the country a big favor by canceling the next two. I won’t call them “debates”. It’s better to call them “confrontations”.

You can contact the Commission on Presidential Confrontations at media@debates.org or (202) 872-1020.
