More censorship, this time of Israeli ambassador to the UN

February 14, 2017 • 1:45 pm

It’s not just Milo who’s demonized; it’s anybody connected with Israel. This tweet was posted yesterday evening, and reportedly shows Columbia University students “shutting him down” by disrupting his talk. When will they ever learn?

This event was dreaded by everyone for days in advance; after all, it’s Israel, Jake, and we can’t have a talk by an Israeli without disruption. Apparently Columbia University had to approve of those invited to attend,

Here’s what some of the protestors shouted:

“Danny Danon you can’t hide, we charge you with genocide,” they chanted as waitlisted guests for Danon’s event stood in line, several bearing Israeli flags.

In addition, a group of chanting protesters interrupted the student event during which Danon addressed the crowd on Israel.

“We’ll be free from the river to the sea, Palestine!” shouted a handful of demonstrators marching up stairs in the lecture hall.

That statement, which calls for the abolition of the state of Israel, is documented in this tweet from Danon himself:

They’re entitled to their opinion, but they’ll never get a two-state solution calling for the abolition of Israel. And these snivelling little brats should learn to let someone speak, and to protest peacefully.

The Reds wipe out capitalism on Mars!

February 14, 2017 • 1:00 pm

This movie came from a tweet by Maria Antonova, a Russian journalist:screen-shot-2017-02-14-at-12-48-38-pm

And here’s the movie, called “Interplanetary Revolution.” It’s a bizarre mix of antiquated and advanced technology, including a spaceship that looks like a trilobite:

Now this movie was reportedly made in 1924, so that’s four years after the Nazi Party adopted the swastika (the flag was designed by Hitler himself), explaining its presence as a right-wing symbol in this early movie. Joseph Stalin appears as well; he had become General Secretary of the party’s Central Committee in 1922, and rose to supreme leadership after Lenin died in the year of this movie (we also see Lenin near the end).  And the fat-cat capitalists are hilarious!

I love these early propaganda films. It doesn’t matter who made them, for they’re a look back at a history we don’t often see these days.

A liberal tells us what liberals “don’t get” about free speech, but she’s the one who doesn’t get it

February 14, 2017 • 10:45 am

We’ve met Katherine Cross before, in a piece she wrote defending the punching of Nazis. Identified as “a pizza loving feminist sociologist, trans Latina, and amateur slug herder, working on her PhD at the CUNY Graduate Centre,” she writes for The Establishment, which I don’t read but, upon perusal, seems to be a slightly upscale version of PuffHo—about as Authoritarian Leftist as they come. It should in fact be called The Authoritarian. (To wit: its headline article today the Grammys for blatant racism: they gave Adele an award for best album of the year but ignored Beyonce because, they say, she was black. They also spell “Black” with a capital letter and “white” without one.)

The article Cross wrote before, “Why punching Nazis is not only ethical, but imperative,” was a deeply flawed piece of writing, and I took it apart on this site. But she’s equaled it with her latest piece on Alternet, “What liberals don’t get about free speech in the age of Trump.” Yet most of us have already gotten what we’re said not to “get,” and I’m surprised that this piece was published in the first place.  I suspect that, like PuffHo, The Establishment publishes left-wing pieces with little or no remuneration to their authors.

But on to the piece, which I’ll summarize briefly. Cross says there are two things we liberals don’t get about free speech. She is, of course, mostly concerned with Milo Yiannopoulos.

1.) Free speech doesn’t entitle anyone to a platform anywhere you want. Cross says this:

This is the key difference. You can think whatever you like, and even say it without fear of government reprisal, but when you introduce force-multipliers for speech into the equation, things begin to get very hazy indeed. You have a right to a view; do you have a right to pronounce it to millions of New York Times readers, however? No. We have no problem recognizing this when it’s about something silly like Bigfoot, but the minute matters of consequence enter the frame, suddenly people are mystified by the very existence of standards.

To speak to so vast an audience is a privilege, not a right. To speak through a newspaper or magazine column, a TV talk show, an interview on national TV, a speech at a university, or a primetime debate program, is, by its very nature, a privilege not open to all. There are billions of people on this planet, each speaking their views at any one time, but they can’t all appear on the Today show. Once again, we intuitively grasp this basic logistical matter, but forget about it entirely when a raving bigot shows up, feeling cornered by an abstract principle into insisting that he or she be given not only space to speak, but the largest possible platform and audience for it.

It has been the pride of my life to be able to write editorial copy and speak at universities and conferences around the world. I do not, however, delude myself into thinking I have a right to any of these things. They are privileges I have earned. I have a right to the views I espouse here; I do not have a specific right to force the editors of The Establishment to use their platform for that espousal.

Duh! Is there anybody here who hasn’t grasped the difference between asserting a right to speak at, say, a college, and a right to speak in a public square? Milo didn’t have an a priori right to speak at Berkeley or any other school: he gained that right because he was invited to speak by the College Republicans. Once he was asked and accepted, he had a right to speak. Even the University Chancellor recognized that right, and urged the Berkeley community to act accordingly. And once Yiannopoulos had that right, he could say anything he wanted unless he violated the courts’ interpretation of the First Amendment: permitting speech so long as the speaker’s words didn’t urge listeners to commit immediate violence. Of course Milo’s presence—he wasn’t allowed to talk—did lead to violence from protestors, but that wasn’t was his words were designed to do: it’s what his mere bodily appearance produced. You cannot ban someone from speaking simply because those who thought they might be offended by his speech (and not inflamed to do his bidding) start rioting, hurting people, and destroying property.

That much is obvious. So on to Cross’s second point:

2.) Free speech has to be balanced against another “right”: the right for society to be free of speech that will damage it. To her credit, Cross doesn’t say that people like Milo abrogate people’s right “to not be offended.” Instead, she says that Milo’s words were designed to encourage his followers to further marginalize and physically injure those already marginalized, which will create a dystopian society. To further her argument, Cross brings up—yes, again—the Nazis:

So many people are hung up on Yiannopoulos’ right to free speech (without enumerating the specifics, e.g. a right to this platform, a right to payment from this institution, et cetera, none of which are democratic rights per se), while ignoring the rights his hate-mongering specifically abridges.

. . . What I protest in Yiannopoulos’ “Dangerous Faggot Tour” is that he incites action, which cannot be ignored or brushed off by its targets. Yet despite being central to the issue, it is rarely the focus of chest-beating free-speech absolutism in the editorial pages.

She then quotes Ron Rosenbaum, and expert on the history of Nazism:

For Trump, his army of trolls, and his ideological lieutenants like Yiannopoulos and Richard Spencer, words are playthings used to win a moment’s battle, to elicit a reaction, and to hide as much as to reveal. It is their actions that speak true.

And then, mentioning Hannah Arendt, Cross says this:

Hannah Arendt had the right of it when, in her Origins of Totalitarianism, she explained what the purpose of Nazi propaganda was. It was not a proposition presented for debate, compromise, and rebuttal, but an alternative reality that justified its own existence:

“The assumption of a Jewish world conspiracy was transformed by totalitarian propaganda from an objective, arguable matter into the chief element of the Nazi reality; the point was the Nazis acted as though the world were dominated by Jews and needed a counterconspiracy to defend itself.”

In other words, these were articles of faith that served to justify Nazism’s aims. They told the world what had to be true in order for race laws and death camps to make moral sense. This was not a matter for debate, though it had been disproven on its merits time and time again.

And, at the end, although Cross claims she’s not trying to excuse the violent protests at Berkeley, she says she understands why they did what they did: they had to fight Milo’s “actions”—or rather, what she sees as his call for immediate violence:

This is not to say that quests for truth are pointless — quite the opposite — but rather that we should understand what they can and cannot do. You cannot disprove the truth of an action; you can only combat it.This essay will undoubtedly be positioned as a defense of the violence at Berkeley. It isn’t; a disquisition on the merits of political violence as such requires its own article. But the argument I’ve made here should serve as an explanation of why, when faced with an establishment that is deaf to all reason, some may have felt setting lighting equipment on fire to be their only recourse.

Inasmuch as it stopped Yiannopoulos from radicalizing his audience into committing hate crimes against their fellow students, the protest achieved something meaningful. But it diminishes us to flush that down the memory hole of another pointless debate about tediously abstract and immature constructions of free speech. If we must do this, then let us do it properly. Let us call actions by their names, acknowledge the harms of those actions, and then, with the terms of debate and its principles properly grounded, discuss the matter.

After all, is that not what those of us who care about words are obliged to do?

This is deeply confused. First Cross tells us that there is a “right” to be free from the kind of violence-inducing speech promulgated by Yiannopoulos, then says that we must combat that “hate speech” by calling it what it is: not only hate speech, but speech designed to wreck society. But we’re already doing that! Plenty of liberal outlets have done what Cross says we’re “obliged” to do: argue against Milo, produce counter-speech, and even accuse him of “hate speech.”  So what’s the problem? And if you can’t “disprove” the truth of an action (i.e., speech), why even “discuss and debate the matter.” What’s the point if listeners are “deaf to reason”?

Why did Cross even write this piece?

Her problem is that she indicts Milo for truly violating the First Amendment as interpreted by the courts—for making speeches that he knows will move his audience to violence. Well, that’s just not true, and if it were, Cross or anybody else could take Milo to court for violating the Constitution.

Milo doesn’t call for violence. Yes, he does stuff that I think is unwise, like publicly naming a transgender student and was (so I hear) about to urge Berkeley students to name fellow students who are undocumented immigrants. To my mind that’s wrong, but I say that as a person. As someone acquainted with the law, though, I have to add that although I think it’s wrong, it’s also legal, and I’ll defend Milo’s right to say those kinds of things.

There is no “right” for people to not be subject to speech like Milo’s. If they don’t like it, they don’t have to listen to his talks. But the kind of speeches Milo gives on campuses do not violate the First Amendment, and thus abrogate no legal rights. The Constitution does not prohibit, nor has it been interpreted to prohibit, calls for social changes that other people think are harmful. If that were the case, then every Muslim could riot when Charlie Hebdo cartoons are published, every black person could riot when some of the tenets of the Black Lives Matter movement are questioned, and every believer could riot when religion is criticized. For indeed, all of those offended by such speech believe it will wreck society. Cross sees herself as the Arbiter of Non-Damaging speech, and thereby guts the First Amendment, as many Authoritarian Leftists do.

And I’ll add here that the censorship of a free press, which is what the Nazis did when they assumed power, was done in the name of keeping German society peaceful.

 

Directionally asymmetrical eyes (and behavior) in a squid: left eye big, right eye small

February 14, 2017 • 9:15 am

Last week I wrote three posts (1, 2, and 3) on “directional asymmetry”: the phenomenon whereby an animal is asymmetrical in a way that shows “handedness”; that is, a trait is differentially expressed or developed on a consistent side of the body, either the right or the left. One example is the enlarged canine tooth of male narwhals, which is always on the left side, or our own hearts, which tilt toward the left side of the body. (A random appearance of asymmetry, such as the big claw of male fiddler crabs, which can be on either the right or the left, is called “anti-symmetry”.)

I’ve long been fascinated by directional asymmetry because it shows that genes can “know” that they’re on the left versus right side of the body, and express themselves accordingly. This is a puzzle for an organism that’s truly bilaterally symmetrical, as I don’t see a way for a gene to detect left versus right. Of course once an initial directional asymmetry has developed, then further directional asymmetries can cue off that one, so the problem is largely solved.

In the second of the three posts mentioned above, I discussed some recent findings suggesting how directional asymmetry can develop (and hence evolve) from a zygote, but we still don’t know a lot about this. What I want to do today is describe a new case of directional asymmetry reported in a recent paper by Kate Thomas et al. in the Philosophical Transactions of the Royal Society (free download; reference below). Actually there are two cases, and they’re in a group appropriately called “the cockeyed squids.”

These deep-sea squid live between about 150-800 meters beneath the ocean surface (older squids go deeper)—an area where there’s diffuse but weak light from above and near total darkness below. To deal with a situation in which they can spot predators or prey against either a light background (above) or a dark background (below; the organisms looked for there are bioluminiscent, i.e., they glow), the squid have developed directionally asymmetrical eyes:  they have a big eye that’s twice the size of a smaller eye, and the big one is always on the left. (The eyes start out symmetrical in juveniles but then differentially enlarge). The right eye is a hemisphere, while the big left eye is not only “semi-tubular”, but often has a yellowish pigmentation in the lens, said to be able to help the squid recognize “counterilluminated” objects above highlighted against the lighter ocean surface. The difference in eye size is mirrored in the brain’s optic lobes, as the left lobe is twice as large as the right.

Here’s what two species examined look like; the disparity in eye sizes is striking:

f1-large
(from paper) The two species examined in this study: (a) an adult Histioteuthis heteropsis (ROV image), (b) a semi-transparent juvenile H. heteropsis showing the differently sized and shaped eyes, (c) the left and right side of a juvenile Stigmatoteuthis dofleini, and (d) an adult S. dofleini (ROV image).

The squid, examined by a remotely-operated submarine sent into the depths of Monterey Bay in California, were seen in two positions: the “J-pose” (i and ii below) in which the arms are curled up around the head, and the “I-pose,” in which the squid are straight, with tentacles out and pointed down (the head and mantle are always oriented toward the surface). The authors speculate that the J-pose is defensive and is probably a startle reaction to the submarine. Here are the poses and other shots of the eye, one showing the yellow-pigmentation of the big eye (c iii)

f2-large
(from paper): Still frames of Histioteuthis heteropsis from in situ ROV video. (a) Examples of an adult (i) and a juvenile (ii) in the J-pose posture. (b) Sequential images (i–iii) of a ‘ratcheting’ turn in the Straight Arms posture. The sequence shows the starting position (i), twisting of the mantle relative to the head (ii), and the ending position (iii). (c) A juvenile (i) and adult (ii) with unpigmented large left lenses, and an adult (iii) with a yellow-pigmented left lens.

Why the asymmetry? One clue is that the squids tilt themselves a bit so that the big eye basically faces up, while the small eye faces horizontally and down, so they scan different parts of the ocean. Here is the typical orientation of squids in the I-pose: the body of adults is tilted 20° from the vertical:

screen-shot-2017-02-14-at-7-31-52-am
(from paper): Histioteuthid eye and body axis orientations (left, solid white lines) relative to a vertical axis (left, dotted white lines). (a) Absolute eye orientations, with 0° indicating an eye oriented directly upward and 180° directly downward. Orientations of the larger, left eye are plotted on the right (grey) and the smaller, right eye on the left (black) to show where the eyes are directed relative to one another. (b) Absolute body axis orientations with 0° indicating a vertical, tail-up position and 180° representing a vertical, tail-down position. Observations are shaded by posture observed at first sight of the animal: J-pose (black), Straight Arms (grey), or unknown/unseen (unfilled).

This asymmetrical orientation, taken along with examination of the eye itself, led the authors to conclude that the squid has differential ranges of vision of the two eyes. The big eye sees from directly horizontally (90° to a a line drawn vertically to the ocean surface) to directly upwards, while the smaller eye has a bigger angle, seeing from about 45 degrees upward to directly down:

screen-shot-2017-02-14-at-7-34-29-am
(from paper): cross section through both eyes of a histioteuthid showing the approximate field of view for each eye (shaded) given an orientation of 45° for the large left eye and 120° for the small right eye. Adapted with permission from Young

Is this adaptive? And why the asymmetry? The authors suggest that a bigger eye would always be better for seeing both up and down, for it’s able to provide both better resolution and sensitivity. So why doesn’t the squid have big eyes on both sides of the body? We can only guess, but the authors suspect it’s a matter of metabolic economy: eyes are expensive to make and maintain, and are easily injured, so if you don’t need a big eye to look down, better to divert the resources for making one into other features that can enhance reproduction. Here’s how the authors put it (my emphasis):

Visual modelling indicated that the observed orientations of the large and small eyes of histioteuthids were probably important to the evolution of the size dimorphism. When looking at extended scenes, it is nearly impossible to recover the sighting range that is lost going from an upward- to a downward-oriented eye of any size. However, sighting ranges for point-source bioluminescence do not change as substantially with viewing angle. Thus, for an upward-oriented eye viewing a black object, small increases in lens diameter (aperture) produce large gains in sighting distances. However, for a downward-oriented eye viewing a black object, even large increases in lens diameter do little to improve sighting distances. Eyes are metabolically expensive to grow, maintain, and use, so while larger eyes can improve both sensitivity and resolution, selection probably favours an eye just large enough to perform a necessary visual task but no larger. Thus, once each eye has been consistently designated as upward-viewing or horizontal- to downward-viewing through behaviour, it is not difficult to imagine how selection could have favoured increasingly dimorphic specializations in each eye of the ‘cockeyed’ squids.

Now the “metabolic expense” notion is just a hypothesis, and would be hard to test, but it may well be right. Regardless, though, what we do have is yet another case of directional asymmetry in an animal. The question remains how this develops, how the genes that make a bigger eye on the left are differentially expresssed, and whether there are already directionally asymmetrical features in these squid that can act as cues to induce the directional formation of eyes.

Here is a video of the squid taken from the remotely-operated submarine; it doesn’t add much to the description above but does show you the squid in situ.

Simon’s cat: Valentine specials

February 14, 2017 • 8:45 am

We have two Simon’s Cat specials for Valentine’s Day. In the first, Simon Tofield shows how he makes one of the pictures used in the second video.  I don’t think the cat’s inamorata is thrilled to get a box o’ mice.

And here’s the final product for today: “Dinner Date: Starters.” Note how the cat is startled by a cucumber, something I’ve mentioned before.

Google animated Valentine’s Doodle is also a game

February 14, 2017 • 8:15 am

Today’s Google Doodle is a Valentine’s Day animation—and a game. It features a Philippine pangolin (Manis culionensis), an at-risk species. The object of the game, as described by Google, is to get the animal home to the Philippines to find love. It’s been a four-day Doodle, and you can see the description of today, the last day, here. You play using your keyboard.

Readers’ wildlife video: Valentine’s Day special

February 14, 2017 • 7:30 am

Today we have a special Valentine’s Day video from Tara Tanaka (Flickr page here, Vimeo page here); it’s culled “Black Vulture Romance: Just one look. . . “, and shows that you don’t have to be pretty to find love. Tara’s notes:

I was culling videos from my last birding trip around Florida, and realized that this clip was perfect for Valentine’s Day. It almost looked like a flip of her wing was the thing that so piqued his interest and set off his dramatic display. Another vulture photo-bombed the couple, and then another bird’s alarm call broke the mood for this romantic pair. The loud bird call in the background is a Limpkin.

Be sure to watch it on the Vimeo site, enlarged and in high definition. (The Black Vulture is Coragyps atratus, the limpkin is Aramus guarauna.)

Tuesday: Hili dialogue

February 14, 2017 • 6:30 am

Good morning on a balmy February 14 in Chicago: Valentine’s Day! ♥ ♥ ♥ ♥ ♥ I hope you sent a nice treat to your loved one(s).  Meanwhile, a Pakistani court has banned Valentine’s Day in the whole country, declaring that it’s “against the teachings of Islam” (what: they don’t like love?),  and the flower-sellers are deeply upset.  So be it.  Appropriately, today’s food holiday is National Cream-Filled Chocolates Day (I prefer what I got–giant fresh strawberries dipped in rich, dark chocolate). But it’s also “V-Day,” a day to mark and decry violence against women and girls. (Since it was started by Eve Ensler, the “V” stands for “Victory, Valentine, and Vagina.”)

On this day in 1502, during the Spanish Inquisition, the Catholic Monarchs ordered Muslims in Granada to convert to Catholicism or leave Spain. That’s a reminder that, in the past, Catholics were as intolerant of infidels as some Muslims are now. Exactly 54 years later, the Church declared Thomas Cranmer a heretic for separating the English church from Catholicism (and translating Scripture into English), and he was executed.  In 1859, Oregon became a state, and Arizona followed on this day in 1912. In 1929, the infamous St. Valentine’s Day Massacre occurred in Chicago, with seven rivals of Al Capone gunned down in a garage. On February 14, 1945, the fire-bombing of Dresden by the Allies began, and in 1956, Khrushcheve condemned Stalin in a secret speech—one of the first public criticisms of the former tyrant. In 1990, the Voyager I spacecraft took the famous “pale blue dot” photograph and, finally, on this day in 2005, YouTube was launched, making free kitten videos available to all.

Here’s the “pale blue dot” photo (you can see it as a light speck in the vertical brown band to the right); and let us remember what Carl Sagan said about it in a speech at Cornell University:

We succeeded in taking that picture, and, if you look at it, you see a dot. That’s here. That’s home. That’s us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there – on a mote of dust, suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light.

[…] To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we’ve ever known.

Wodehouse (both 1975), James Bond (the ornithologist whose name was used by Ian Fleming, 1989), John Ehrlichmann (1999), and jazz pianist George Shearing (whom Jack Kerouac called “The Great God Shearing”, 2011).
