Loyalty vs. Obedience

     A recurring theme on this blog might be distinctions between easily confused concepts. I started out with a post about the difference between faith and belief and I've also written on the difference between theory and fact. Yesterday the CBC reported on a letter sent to Parks Canada employees warning them not to criticize the government and "reminding them of their duty of loyalty". The author of the letter is confusing loyalty with obedience.

     This isn't a new confusion. Shakespeare addressed it very well in King Lear, where the aging king rewarded his daughters Goneril and Regan for their fawning and empty praise, and condemned as disloyal his daughter Cordelia who alone was willing to tell him that his actions would lead to his downfall. It is soon revealed, of course, that Cordelia was the only genuinely loyal daughter Lear had.

     King Lear illustrates very well the difference between loyalty and obedience. Loyalty, whether to a person or an institution, involves more than simply doing what the object of loyalty might desire or demand; it is a genuine concern for the welfare of that person or institution, a commitment to act in their best interests, including providing needed (but perhaps unwanted) counsel. Obedience, in contrast, is simply carrying out instructions.
   
     So what the government is demanding from its employees is not loyalty but obedience. It orders them not to criticize its policies, and expects them to obey. It doesn't care about the reasons for criticism; like King Lear, it just wants to hear what it wants to hear. (We see this also with the Conservatives' systematic removal of any sort of non-partisan information-gathering or expert advisors from the federal budget. They know what they want to do, and have no interest in anyone suggesting what they ought to do.)
     Demanding obedience of public servants is entirely appropriate. The elected government must be able to implement policy by directing public employees to carry it out. That's not controversial at all, and in fact is central to all employment relationships; within the scope of one's employment, one is obliged to obey one's employer's directions. But only within the scope of that employment.

     It's not always a clear line, of course. If you're employed as a commercial airline pilot, your job is flying planes and what you do or say on your own time is generally your own business so long as it doesn't impact on your ability to fly planes safely and on time, but if you publicly badmouth your airline and negatively affect ticket sales, even on your own time, you can expect to be fired.
     That's the argument that the Conservative government is trying to use in justifying its attempts to exert greater control over the speech of public servants, and superficially it seems reasonable. But there's a crucial difference. Government is not a business, at least not in the sense of a competitive market enterprise pursuing profit. An airline can lose market share and thus profits if its reputation suffers. Government cannot. Government is government, regardless of who happens to form it. A political party can certainly be harmed by damage to its reputation, but so what? No civil servant is obliged to help a party get or stay elected.

     Civil servants owe a limited duty of obedience to whatever political party happens to form the government, but if they owe a duty of loyalty it is to the nation and its citizens, not to the political party. Loyalty to the nation demands providing honest counsel, engaging in the democratic process, and saying what one thinks needs to be said. Sometimes that will be at odds with what the party in power wants us to hear. Too bad. We the people don't always have access to all the information we need to make informed decisions around election time, and so it's vital that we hear from everyone who might know something relevant. IT IS NOT for government to control that dialogue!

After Images: Amateur Adventures in Neuroscience

     Many years ago (perhaps as early as the 1980s?), I remember reading in a book about artificial intelligence something about attempts to develop vision systems where researchers were surprised to find the processed image essentially going blank after a few seconds, if the camera were left pointed at a static scene. I don't remember the details of the book or the experiment, but it's something I've found myself thinking about from time to time, and of course it makes a certain amount of sense when you think about how neural networks work. After all, visual processing isn't just a matter of detecting the intensity of each pixel, but involves picking out patterns: edges, lines, movement, and so on. Layer upon layer of neurons perform this task, each responding to a particular, relatively simple combination of inputs from several neighbouring neurons to decide things like whether or not its tiny area of the visual field includes a boundary between different regions.

     It has recently occurred to me that I may have observed this very same phenomenon with the visual system in my own brain. I had tried to duplicate the result by staring very intently at a single point long enough for things to fade, but that never worked; even in a very calm environment where nothing appears to be moving, the semi-random saccadic eye movements force your field of vision to twitch just enough to keep things dynamic for your neural net.
     But there is a way to imprint a static image directly onto your retina, without any possibility of its moving around. I noticed this one morning as I woke up, and the high contrast image of the daylight through my window against the darkness of the rest of my room left an afterimage when I closed my eyes again. At first the image was a very sharp outline of my window, with every slat of the Viennese blind distinctly visible. But soon it began to blur and fade.
     Afterimages are caused by the retinal cells in your eye being fatigued. The cells fire when exposed to light, sending a signal through the optic nerve to the brain, but it uses metabolic resources to fire, and it takes time to regenerate those resources. Now, I thought the fading of the afterimage, after I closed my eyes again, was simply a matter of my retinal cells recovering from the effort. But then I found I could restore the afterimage for a short time by opening my eyes without looking in the direction of the window. That is, I controlled for the possibility of simply re-burning a similar after image, by looking at my darkened room rather than the window. And the image came back, though as before, only for a few seconds before it faded. I was able to make this happen again and again, for several minutes. Evidently it can take quite a while for retinal cells to rest fully.

     So here's what I think is happening here. The after image on my retina is very static, because it's fixed to actual retinal cells. The layers in my neural net quickly cease to recognize it as a pattern, and stop reporting it, precisely because it is so static. In other words, the brain automatically filters out these artifacts of the optic system itself, compensating for the fact that one retinal cell might be giving less than its normal response and another nearby one is giving its full signal, and reconstructing what the scene "really" looks like without the local variations of sensitivity.
     And when you think about it, it makes perfect sense that our visual system would adapt this way, since it's supposed to tell us what's happening in the world around us, not irrelevant administrative details about how each retinal cell is performing.

LARP Ethics and Why Linda Gibbons' Case Isn't Inflaming the Passions of Civil Liberty Groups

     The other day, a friend called my attention to the case of Linda Gibbons, who has spent a great deal of time in jail in connection with picketing abortion clinics. My friend was concerned about what he sees as hypocrisy among civil liberty groups who have not rallied to defend Ms. Gibbon's free speech, apparently because it's speech that goes against the right to have an abortion which civil liberty groups support.

     I was troubled by this as well at first, and still am to some extent. My own view is that freedom of speech is the most basic, most fundamental, most indispensable right in any society that aspires to being in any way just. I've long held that the proper approach to things like hate speech is to counter it forcefully with intelligent and persuasive criticism, rather than to attempt to silence it through censorship. So my gut feeling is that people ought to be permitted to peacefully express their opinions anywhere and at any time, and my instinct is that injunctions against peaceful protest had better have very, very good reasons or they shouldn't be granted.
     The problem for me is that I don't really know if the injunctions in this case were really warranted. On the one hand, there's the freedom of speech point, which militates very strongly against any such injunction. Yet at the same time, we have to remember the situation on the ground in the access to abortion issue; it's not always easy to draw the line between legitimate, peaceful demonstration and intimidation which has no place in a free society.
     Intimidation, real menacing intimidation, can be quite subtle, and depends very much upon context. Let's consider the circumstances. First, genuine violence has been carried out against abortion clinics, their staffs and patients. Moreover, not all involvement in violence is direct; there have been (and for all I know still are) websites that publish the names and home addresses of abortion providers with the implied intention of facilitating harming them. So the act of peacefully standing by an abortion clinic, expressing your disapproval, isn't necessarily going to be interpreted that way; there's also the unavoidable unspoken message: "I see you, I know what you're doing, and I think you're a murderer."
     Second, consider the demographics of the targets of protests: women with unwanted pregnancies. A significant number are likely alone, feeling especially vulnerable and struggling with a very difficult life choice, and especially in need of privacy. Some may have parents or friends or family from whom they wish to keep this decision. In that context, even a genuinely peaceful protest can be especially intimidating.

     I think what made me sensitive to this issue was thinking about a question in LARP ethics, of all things, several years ago. The question arose: is it ever okay to roleplay a rape scene? (I am assuming that the roleplayed scene would be described rather than physically acted out.) In general, I see LARP (when it's done well, that is) as an expressive medium, a legitimate form of theater in which no subject matter should be off-limits. However, one always needs to be sensitive to one's audience, and especially so in LARP where one's audience may be just one person. If I and a female player are off in the woods ostensibly seeking the lair of some ogre, and then when no one else is around I suddenly turn on my partner and roleplay an assault, I had better be very sure she knows and trusts me very well, and understands the artistic legitimacy of what my character is doing and why, because otherwise the unintended message she receives could be "Oh look. We're along in the woods, I'm bigger than you, and the thought of raping you just crossed my mind. Of course, it doesn't have to be rape..." That is absolutely not a message you want to send, and so I reluctantly concluded that, in some contexts, it's legitimate to limit certain kinds of speech, even when the intent is perfectly innocent.
     I'm not entirely comfortable with that, but I can live with it, in part because other contexts exist where it is safe to discuss the same themes without realistic fear of being misunderstood. (Some people will misunderstand you no matter what, of course, but that can't be helped.) If one can't responsibly address issues of rape in a LARP, one can still write novels, essays, and discuss the topic in safe environments where no threat can reasonably be inferred.

     And so the same seems to me to be true of the injunctions Ms. Gibbons violated. It does seem extreme, on the face of it, to prevent all protesting within a certain distance of the abortion clinic, and so I'm not fully comfortable with that. At the same time, I can see arguments for why such an injunction might well be reasonable, and of course she is still free to express her views anywhere else.

      (I feel a need to contrast this with other so-called "free speech zones", by the way, where authorities prohibit any demonstration or expression of certain views within a certain distance of a motorcade route or conference site. I am steadfastly against those sorts of limits, and the difference there is about who has the power, and who gets to control the message. A lone young woman going to terminate a pregnancy has virtually no power, and is very vulnerable. The President of the United States giving a speech to campaign contributors doesn't fall into that category, and his purpose in clearing the streets of signs and t-shirts of contrary messages isn't to be shielded from intimidation, but to control the image: he looks better on TV when he appears in front of crowds of enthusiastic supporters than if there are signs of dissent.)

     But as I said, I'm not really sure where I stand on this one, because I'm not fully convinced the original injunctions were fully reasonable. I can see reasons why they might be, but I'm uncomfortable about any limits on free speech. And that, at least, I think explains why there hasn't been as much of an outcry from civil liberty groups about Ms. Gibbons' case. Two important civil liberties are in conflict here, the right to seek lawful medical intervention without being intimidated, against the right to free speech. The case is nuanced, and it's not immediately clear which side someone who values both liberties should take.

Why I'm Against the Death Penalty

     The other day, I mentioned parenthetically that I would get to my reasons for opposing capital punishment in another post. Ere I forget, I'm writing that another post now. I have two main reasons for my position. One is moral/philosophical, and I might get to that in another post. The other is legal, and that's what I'm going to talk about in this article.

     There are two kinds of rights we have in our legal system, substantive and procedural. Substantive rights include what we usually think of as basic human rights (rights not to be tortured, to worship or believe what one will, to vote in elections, and so forth) but also can include special rights such as those gained under a contract or by statute; under a contract, if you do your part, you have a right to what the other party promised. Substantive rights can be disputed at times, and won or lost under various circumstances.
     This is where procedural rights come into play. Procedural rights are rights to a fair process (hence the name) by which substantive rights can be determined. So, for example, you have a procedural right to a fair trial to decide whether or not you lose your substantive right not to be imprisoned.
     Procedural rights are interesting because although we usually speak of them as belonging to the accused (in criminal matters) or to the litigants themselves in civil matters, they are actually more diffusely owned by society as a whole. That is, we all have an interest in procedural fairness, and we all lose if our procedures become unfair (even if some of us happen to benefit from the unfairness). It's just that the parties to the dispute are the ones most immediately concerned with the process, and thus most likely to zealously assert those procedural rights. Besides, if one party should choose to waive those rights in a given case, no one else is in a position to complain about unfairness.
     Now, while substantive rights can be won or lost, procedural rights ought to be absolute, in part because they don't just belong to the accused. There is no crime so heinous that we would want to say you lose your right to a fair trial; no matter what you're accused of, you have a right to insist that the state prove its case against you before it can mete out punishment. And society also has a right to insist this as well, because (1) none of the rest of us want the state to be able to punish us without proof, and (2) society has an interest in making sure that we've got the right guy; it wouldn't do to convict you while the real culprit goes free.
     My legal problem with capital punishment, then, is not that it takes away substantive rights, but that it extinguishes all rights, substantive and procedural, absolutely and irrevocably. Once someone is executed, there is no possibility that new evidence can exonerate them, or that the law on sentencing could be changed, or that the Crown might grant a pardon. While I have considerable trust in the legal system in principle, part of that trust derives from the fact that it includes so many error-correction mechanisms, such as appeals, Acts of Parliament, and Crown prerogatives. Capital punishment deprives society of the opportunity to correct its errors.

Little Joys of Discovery #1

     Every so often I learn something new in the most delightful way. Today I was out weeding the garden, turning soil to prepare for planting some vegetables, when I was surprised to come across this:


     As you can see, it's part of a wasp nest. The top image shows what surprised me: instead of hanging from the bottom of a branch somewhere, it's attached to the roots of the grass I was removing from the vegetable garden. That is, the paper nest had be constructed completely underground. I'm used to seeing wasp nests above ground, in trees or under the eaves of my garage, like this one, which I excised from our apple tree one autumn a few years ago and have been keeping in a sealed plastic box because it was just such a fabulous specimen:


    Now, you may have known this all along, but it simply never occurred to me that wasps might go to all the trouble to excavate an underground chamber and then go ahead and make this elaborate paper structure as well. I suppose I just assumed that what with the paper and the stings, wasps wouldn't bother to dig like this. And yet they do, and I feel richer for having found that out first-hand, rather than from a book or a blog, as much as I like books and blogs.

     I recall the same sort of experience a few years ago, lying on the grass and happening to notice a bee landing nearby carrying a piece of a leaf, before it disappeared into a tiny burrow in the ground. I was astonished. I had, of course, heard all about leafcutter ants, and their marvellous underground fungus farms, but somehow I had never heard of leafcutter bees. So I promptly went and looked them up, and it turns out they're very important pollinators for many crops. A few years later, I was replacing some rotten boards on our deck, and found tunnels lined with leaves, and packed with yellow powdery deposits I assume was pollen, stored for the bee's young. (Yes, singular possessive "bee's"; apparently leafcutter bees are a solitary species.) I wish I had taken a picture.

     While I had the camera out for the wasp nest, I also took a couple of other shots of delightful discoveries I happened upon today, though neither quite so surprising to me as learning that wasps built paper nests underground. After all, I knew that robins ate worms, though I was puzzled at why this one seemed to be just idly sitting there on the wire for so long without either eating its prey or taking it home to feed its chicks.

      I also knew that chives spread like weeds, but I was still pleased to find this one, almost as it if had been posing for a photo. Usually I find it disguised as tall grass, hiding from the lawnmower behind the raspberry bushes.


     So much for today's self-indulgent photo essay.

You'd feel differently if...

     Yesterday I wrote about the idea of using convicted criminals for medical experiments, prompted by a Facebook status/share/chainletter thingy. Reading through the comments in support of this barbaric idea, I saw a few people who spoke out against it on basically humanitarian grounds, and the responses to these typically took the form of this argument: "You wouldn't say that if you or someone you loved were a victim of these monsters!"

    This is a very common argument, although I rarely see it in any context outside of crime and punishment. I happen to be opposed to the death penalty (for reasons I'll get to in another post), and nearly every time I get into a debate with someone who's in favour, they bring it up. It's easy to understand why: it's a very emotionally powerful argument, and what's more, it appears to be very effective at bringing out a contradiction in the position of the one arguing against capital punishment. How hypocritical, you might say, that I would oppose the death penalty in general but favour it for someone who had killed one of my loved ones. How hypocritical that I might oppose torture for molesters of other people's children while calling for the torture of anyone who molested my own.

     But there's a reason why we don't see this form of argument in other contexts: it's because it's actually a pretty stupid argument, when you stop to think about it carefully. Yes, it's true that I'd probably strongly desire the death of someone who murdered someone I loved. So what? Since when does powerful emotional trauma make someone a better judge of what is to be done? Is it not widely accepted in most other contexts that a strong emotional investment in an issue usually disqualifies one from making rational, objective decisions? We require judges to recuse themselves from hearing cases where they have close connections to one or both parties, and it's generally better if your surgeon isn't also your lover. Likewise, decisions concerning penal policy probably ought not to be made by those with an overwhelming personal agenda.

     It goes farther than that, though. Let's suppose we accepted the idea that overwhelming emotional desires made people better qualified to make policy decisions. It'd be hard to argue against a policy whereby the government provided free heroin to everyone on demand; after all, you'd feel differently if you were addicted to heroin and going through withdrawals!
     Indeed, this is where the argument finally becomes self-defeating. After all, it relies in large part on our shared sense of moral outrage against pedophiles and violent criminals; we want to say that we are entitled to judge these people's actions as wrong. Yet much of the time, probably most of the time, what they do is driven by overwhelming emotional desires. "Don't tell me not to molest children," one might tell us, "You'd feel differently if you were subject to powerful pedophiliac urges!" Well, yeah, I would feel differently. But I'm entitled to say I'd still be wrong to act on those urges, even if I had them.

     And so, by the same reasoning, I can say that while I might desperately want the state to execute someone who'd murdered someone I loved, it'd still be bad policy and bad for society at large to indulge that desire. It's natural, and perhaps even healthy, to want things that are ultimately bad for us. It's also right and proper to refuse to satisfy those wants.

On Using Prisoners for Medical Experiments

     This morning, one of my friends on Facebook shared an image which was basically just the following text: "Why test on Animals when we have Prisons full of Pedophiles?"

     It's an attractive idea. The the posting from which it was shared has, as of this moment, 44,463 shares and 3,169 likes. Of the hundred or so comments I skimmed through, a significant majority were enthusiastic approval, and only a tiny handful expressed reservations. Of those, all of them were based on a vague notion that cruelty and revenge are barbaric, and those were invariably criticized with almost as much venom as that directed against the pedophiles themselves.
     But as viscerally appealing as it might be to try to extract some positive benefit to society from people who do so much harm, it's a terribly dangerous idea, and so much more so because the danger is so subtle. I mean, on the face of it, what's not to like? Evil people suffer, good people benefit with medical cures.

     What's not to like is the insidious corrupting effect this idea will inevitably have on the administration of justice. The only consideration in finding someone guilty or not guilty of a crime should be whether or not the evidence points beyond a reasonable doubt towards guilt. A person should never be found guilty for reasons other than actually being guilty, and the danger of turning convicted criminals into any kind of valuable resource, whether it be labour, medical test subjects, or organ donors, is that someone will have an interest in seeing people convicted in order to realize the benefits of that resource.

     Imagine, for instance, that you are a judge or juror in a system where those convicted of serious crimes are executed and harvested for organ transplants. Imagine also that you have a child who will die without a liver transplant in the next month or so. The case before you is a man accused of a particularly nasty violent crime, and the evidence suggests that he's the most likely suspect. How much doubt is reasonable, when that doubt potentially costs your child a liver?

     That sounds like an extreme case, and we don't (yet) harvest criminals for organs in North America. (In Canada, we don't even execute them, so it's less likely to be a problem here unless we reinstate the death penalty.) And sure, the potential benefit from a cure found by experimentation on a single accused is so remote that it shouldn't influence the decision making in a single case, right?
     Well, not necessarily. The beneficiaries of a policy that made convicted pedophiles into test subjects wouldn't immediately be the patients whose diseases might one day be cured, but the pharmaceutical (or cosmetics?) companies looking for test subjects. There's value in that, monetary value. Profit. And where there's profit as an incentive, it'll find a way to grow.
     Consider the case of Mark Ciavarella, a judge in Pennsylvania recently convicted of receiving around a million dollars in "finders fees" from a for-profit detention center. This organization receives a fee from the state for every person committed to its care, which is how it earns its revenue and hence profits. Evidently they considered it a worthwhile investment to provide Mr. Ciavarella with a financial incentive to find juveniles guilty and sentence them to terms in its facility; more teens in care meant more profits, so up the conviction rate.

     Oh, but that's outrageous corruption, you might say. Obviously, judges who do that sort of thing should be charged and convicted, and just because someone does something illegal doesn't mean the system is bad when it's run by people who obey the law, right?
     Well, no, but there are lots of ways money can influence the system when it has an incentive to do so. And if it's in the financial interests of anyone, whether they be pharmaceutical companies or private prison operators, to increase the conviction rate then they will do so by whatever means is most cost effective, including lobbying for "tougher" laws to make it easier to find an accused guilty, relaxing the evidentiary standards for guilt, removing funding for things like Legal Aid intended to give the accused adequate legal representation, and so on. All of these things we see happening, in the U.S. and also, perhaps, in Canada. (The Conservatives haven't made public any plans for privately operated prisons so far, but they haven't really been very forthcoming about much of anything, and the way they've sold their crime omnibus bill certainly is consistent with such an agenda.)

     Crime is bad. That's something I think we can all agree on, and it's something we all ought to agree on. It follows from crime being bad that we'd all want to reduce it, so there's as little crime as possible. Who could possibly say it would be good to have more crime?
     I'll tell you who. Anyone who profits from it. And turning criminals into a resource for anyone's benefit creates people who profit from it.
