Grander than the Grand Canyon

Just got back from a helicopter flight to, over, and landing in the Grand Canyon. I have a bad track record with outings, but this was sublime (though I'm not sure if anyone could tell, as it was sublime in a manner that had me wrapped in my own headspace).

The Grand Canyon itself is, well, famously grand, but focusing so much on it does a great disservice to the surrounding landscape, which defies description. I was about to construct an analogy involving craftsmen and chisels, but to compare it to human art would be to do the country a disservice and to demean it: It was not carved, but magnificently eroded.

I would not have thought that a landscape so arid would be so shaped by waters, but the entire landscape was full of dry water-courses, canyons, and arroyos; there was little water to be seen, but its trace was everywhere. (Maybe this is because it is so arid, and the soil therefore contains much less organic matter to soak and bind up the water, so that when it does rain, it flows unimpeded?) It was interspersed with cliffs and hills and small mountains -- but never a rolling landscape. Rather, craggy ridges and scarps thrust into the air, seeming to defy geology. One hulking ridge was all rusty-red down one side (from, yes, rust), whereas the other crumbled away in a dark umber, nearly black. In places, ridges jutted up at forty-five degree angles, yet were banded with what for all the world looked like the bands of sedimentary layers. Were they sediments, and were those ridges thrust up tectonically? If not, what other process was responsible? In one place a stepped ridge was in at least four different colours, each step running along the ridge distinct -- the first white, the next yellow, then rust, and finally that dark umber.

Nor was it a dead landscape. Arid, yes, and probably that is why it is so geologically dramatic, because it is thus free of not one but two great sources of erosion, rainfall and organic factors; yet though the great part of the ground was bare and dry, still you'd never have been more than a few steps from a cactus, or spiny bush, or other plant (tough, dry, spiny, thick-leaved) that I cannot even categorise. I saw no animal life save flies, a crow, and a few sea-birds on Lake Meade (which barely counts), but there was a ubiquitous buzz of insects. Somehow this appealed to me even more in some ways than a forest (though I do love to walk in a forest), perhaps because it seemed comprehensible. I don't know the few dozen important plant species, nor yet the insects and many lizards and so on, but in this arid and therefore sparser, slower-moving ecosystem, it had an air, it looked as though one might with study figure it out -- not like even a temperate forest, where I wouldn't even care to guess the order of magnitude of the number of important species. This isn't to say that I dislike a forest just because its ecosystem is too far beyond my grasp, but rather that the lure of attainable comprehension was another attraction of the desert.

The No True Theist fallacy
2012. Photo by Hoang Do., At Grapplers Inc.
petter_haggholm

Whenever a religious fringe group rises up in arms, be it Al-Qaeda, ISIS, Christian murderers of abortion providers, or whatever, pundits amass to fight at the steps of the podium to be first to proclaim that what those people do is not motivated by religion, that "real religion" is not like that. This is bizarre, and either dishonest or foolish.

Let's be clear: I don't like Islam, but there are about a billion and a half Muslims out there who aren't terrorists, the vast majority of whom would (I presume) be no more eager to decapitate people than I would. I am not suggesting that, for instance, ISIS aren't a fringe group. Of course they are. (And of course there are lots of non-Muslim Arabs, and the large majority of Muslims aren't Arabs to begin with.) Nor do I think that Islam is inherently more vicious than Christianity, though the latter has been somewhat defanged by the Enlightenment.

That said, it's very odd that these commentators always insist that any evil whatsoever cannot be motivated by religion, as "properly" understood. It's always other factors -- political, historical, cultural. Of course, all that context is always significant, and sometimes religious divisions are secondary (IRA?), but claiming that it's about history and culture instead of religion is an implicit assertion that religion has no influence on culture and history. If someone says that people are never motivated to evil by religion, they're implying that people's beliefs do not influence their behaviour; or perhaps that religious beliefs aren't important enough to be acted upon.

Well, that's what they would be implying, at any rate, were they not busily committing logical fallacies to protect, pardon me, the sacred cow of religion. If someone does something nice and credits “do unto others” or “whatsoever you do unto the least of my brothers”, if Muslims give to charity and say it's because the Quran tells them to, everyone is happy to accept their stated motivation. But the moment they do something bad, it is widely denied that their motivation could possibly be what they say it is, even if they can cite verses in their support. “No religion condones the killing of innocents,” said Obama, apparently unfamiliar with Psalm 137-9, Hosea 13:16, and other pleasant tidbits.

I don't believe in any of this. I believe that when someone claims to act out of religious conviction, the possibility should be entertained that they may be telling the truth, whether the act be good or evil; moreover, that even if an interpretation is a minority view, that doesn't disqualify it from being religious. I believe that many people take their religion seriously and do act on their beliefs, sometimes to great good and sometimes to great evil. Let me repeat that: Religion in general, and certainly the big monotheistic ones, can motivate people just as easily to good and evil. That, precisely, is the problem—not that people of any religion are somehow intrinsically evil, but that people mistake scriptures for moral compasses.

I cannot empathise with those without empathy

petter_haggholm

When I think about the awful shit happening around the world right now—whether on the murderous level of ISIS (which I shall speak no more of qua too fucking depressing) or the sordid pettiness of the coproliths from 4chan behind #GamerGate, I often find myself in a state not so much of moral outrage as weary bafflement, unable to comprehend the kind of mentality behind it. I don’t think of myself as notably nice, and on occasion I can out of sheer irritability be petty and unpleasant (above baseline levels). Yet the thought of launching a campaign of black hat hacking, libel, and fraud to ruin someone’s career, livelihood, and life, merely because their opinions offend me, feels…unthinkable, quite literally: I can verbalise it, but I don’t know that I can actually think it per se. Thomas Nagel wondered what it is like to be a bat: to see the world through senses and perceptions completely different from those of humans. I do, too, but (albeit with less interest and more distaste) I also wonder what it is like to be that kind of active misogynist.

I read once, a long time ago, the claim that in order to truly understand something, you must believe it—that is, at least briefly entertain the notion, even though you will discard it in the next moment.¹ I do not know whether this is true, but it always seemed to me that it has a ring of truth to it.² I can verbally describe how bats perceive textures with sound modulation and motion via Doppler effects and shifting frequencies, how a particularly base and virulent form of religious extremism perverts people to cutting other people’s heads off, or how criticism of their preferred monoculture appears to stir some basement-dwellers into fomenting anger, but I have no sense at all of the qualia involved.

Sometimes I find myself wondering to what degree this is emotional self defence. Perhaps (part of?) the reason I don’t understand is that I don’t permit myself to understand—that I hesitate to gaze into and have that abyss stare back at me. Of course I don’t want to experience the qualia of being these people: after all, I find them vile and do not ever want to be like them. Perhaps that implies (in the logical sense) that I do not permit myself to understand them. It’s certainly pleasing to be able to honestly say that I cannot fathom what manner of mind would stoop to these levels.

That might not be an unalloyed good, though, because it sounds an awful lot like a defensive flavour of othering, of rejecting these people utterly and as morally subhuman³ to avoid having to suffer the quale of comparing myself to them and finding any moral similarities, however tenuous. Perhaps at the personal level, that’s OK, but on a larger scale, it leads to retributive justice systems where the focus is on ensuring that They—Those People who commit iniquities—suffer their Just Desserts: putting a priority on making rule-breakers suffer rather than minimising harm. Consider the difference between the dystopian prison system of the US with, say, Norway. My gut tells me that if I somehow found myself in the same basement with one of Zoe Quinn’s or Anita Sarkeesian’s erstwhile tormentors, the most satisfying course of action would be to hamper their typing, tweeting, and hacking abilities by breaking both of his elbows. Yet reason and data both tell me that the only way to solve these problems in the longer term is to despise the attitudes and behaviours, yet empathise and build bridges with the perpetrators.

I can’t do that. I couldn’t, even if the opportunity improbably arose—perhaps because I lack the interpersonal skills, perhaps because I lack the moral courage to attempt to understand these people well enough to talk to them, or perhaps because I’m just too judgemental and unforgiving. If, for example, your moral hackles were raised by my suggesting just now that we should on some level attempt to sympathise with the slime currently harrassing Quinn, Sarkeesian, et al, I want to point out that I’ve already described them in such terms as “sordid pettiness”, “coprolite”, “misogynist”, “vile”, and earlier in this sentence, “slime”. In my defense (on the rational side), I let this be my lodestone for personal views, not for voting in political elections—I wouldn’t want to base policy on classifying those people as slime (that and a bit of racism is how you end up with the world’s largest prison population).

Ultimately, though, we all need to remember: The #GamerGate harrassers aren’t sordid, petty, vile, misogynist, slimy coprolites. Like us, they are human beings—they just happen to be particilarly petty, misogynistic people with petty, sordid, coprolitic, and vile opinions, words, and deeds.


¹ If anyone knows the source of this idea, I should be grateful to hear it.

² Put it this way: At the very least, I feel confident that I understand the proposition.

³ I do not regard anyone as inferior on the basis of ethnicity, biological sex, gender identity, &c., but I do judge opinions harshly.

⁴ Not that I’m an expert on the Norwegian justice system, and I’m sure it has many glaring flaws, but surely the focus on rehabilitation and minimising recidivism is more useful to society than basically torturing criminals and teaching them them to hate.

⁵ Inevitably, alas.

⁶ See this Cracked list, item #3. I find it oddly touching.

William Lain Craig seeks Reasons, hits bottom of barrel, and keeps tunnelling
2012. Photo by Hoang Do., At Grapplers Inc.
petter_haggholm
Thus spake WLC.

“Fine-tuning ergo God” is like saying “The odds of drawing just these ten cards are so small, it must be rigged!” when we don’t know the composition of the deck: A glib generalisation, as though every drawing of cards corresponded to a deck of Bicycle playing cards and a probability distribution we are, supposedly, intuitively familiar with. There’s a bait-and-switch here, since for all we know the deck we’re really concerned with is (meta?)physically constrained to nothing but straight flushes. For all we know, the deck might have only ten cards to begin with or the cards might be stuck together with string and Scotch tape.

Of course it’s entirely legitimate to wonder why the parameters of physics are just what they are (and on some level there is presumably a reason), but I find it highly suspect when someone asserts that they were a priori improbable—how exactly do you determine the probability? Can you demonstrate, from first principles of making universes, that there’s a wide range of possible parameters whereof the chemically productive parameters form a small proportion? I’m sure the cosmological community would be fascinated to learn the principles.

Point one—I must call them points, for they aren’t really reasons—point one is juvenile, point three is perversely ironic in the light of two millennia of unresolved theodicy (don’t you think the Cathars had a better idea, until the Catholics murdered them all?), point four is presumably included for the sake of hilarity alone (surely no one is expected to take it seriously?), and point five must have been added after Dr. Craig got drunk and forgot to activate GMail Goggles, but point two is offensive in its duplicity.

Oh well. For this particular atheist, Christmas—well, I think of it more as “juletid” in Swedish, precisely cognate with Yuletide, a pagan term that merged with Christmas when Jesus’s birthday was moved to mid-winter to co-opt older religious celebrations like Saturnalia and, elsewhere, Yule—was never much about religion but rather family, presents, a tree (of likely pagan origin), and good food (much of it based on pork and so presumably frowned upon by Jews like the Nazarene). Or at least, it was not about religion when I grew up. Now there’s always a heavy dose of news articles, editorials, and opinion pieces by Christians who hysterically complain that their holiday is under attack (because they’re not allowed a monopoly), that Jesus and Santa Claus are white, so there!, or (á la Craig) assert that people like me are echoing slogans rather than thinking. I don’t go pissing in his crèche, but ye gods! (both Jesus and the older myths he was based on), this editorialising gets on my nerves.

Email security
2012. Photo by Hoang Do., At Grapplers Inc.
petter_haggholm

Mail encryption

If privacy of your email matters to you, you may want to consider using end-to-end encryption. This is different from using a “secure” email provider: With end-to-end encryption, the sender of the email encrypts it before sending, and the receiver decrypts it after receiving it. It's not decrypted during transit—thus, even your email provider cannot read your email.

Without going into mathematics whose details I’d have to review anyway, suffice to say that PGP is a strong system of email security that, with sensible (default!) settings, cannot be effectively broken with modern technology and modern mathematics.¹ (Strong enough, in fact, that various US security agencies tried to suppress it, and when its creator released it for free to the world, he was taken to court and accused of exporting munitions. The case never really went anywhere.)

PGP uses something called asymmetric encryption. Technical details aside, the nifty and amazing thing about it is it’s what’s known as a public key cryptosystem, meaning that I can give you a bit of password (public) key that you can use to encrypt messages for me, but no one², not even you, can decrypt them…except for me, as I retain a special (private) key with the unique power to decrypt. My public key is here, should you wish to send me secure email.

My preferred solution is a plugin called Enigmail for my mail client of choice, Thunderbird.

PGP with Enigmail in Windows

There are some other solutions, none of which I have used.

PGP for webmail (like GMail) in Chrome

There's a browser plugin, currently for Chrome only though Firefox is in the works, called Mailvelope that will transparently encrypt/decrypt your webmail. There's a helpful guide. For now, there’s another plugin for Firefox, but it has received mixed reviews.

Linux

If you’re using Linux, this shouldn’t be a problem in the first place. Install your mail client of choice and it surely comes with or has an OpenPGP plugin readily available.

Other

Apparently there's an Outlook plugin. There’s a plugin for OS X Mail.app.

Passwords

As a reminder, keep in mind that your security is never stronger than your password; and your password is never safer than the least secure place it is stored. If your password is weak (password, your name, your date of birth…) there’s no helping you. If your password is pretty strong (|%G7j>uT^|:_Z5-F), then that’s no help at all if you used it on LinkedIn when they were hacked and their password database stolen, so that any malicious hacker can just download a database of email addresses paired with their passwords.

The solution is to use strong passwords, and to only use each password in one place—if you steal my LinkedIn password you can hack my LinkedIn account, but you can’t use that password to access my bank, email, blog, or any other account. The drawback of strong, single-use passwords is that you’ll never, ever remember them. The counter is to use software to remember them for you.

My preferred solution is a family of software called KeePass for Windows, KeePassX for Linux, KeePassDroid for Android (my smartphone), and so on. This has the primary feature of storing all my passwords in a very strongly encrypted file. I store this file in Dropbox, which lets me share it between my devices (work computer, home computer, laptop, phone). I don’t consider Dropbox fully trustworthy, but that’s OK: if anyone breaks into my Dropbox account, all they’ll get is a very strongly encrypted archive that requires either major breakthroughs or billions of years to break into (or a side-channel attack like reading over my shoulder, literally or electronically; but if they can do that my passwords don’t matter anyway). Thanks to this, I can use very strong passwords (like -?YhS\[q@V4#]F'/L|#*1z)_S".35/#T), uniquely per website or other service. Meanwhile, I only have to remember one password: the password for KeePass itself (which I shouldn’t use for anything else).

The KeePass family of software also tend to come with good password generators, which can generate garbled gobbledygook like the above, and/or include constraints if a given website won’t let you use special characters (e.g. you can tell it to generate a random password 10 characters long with letters and digits but nothing else, which includes at least one letter and one digit). You can also use it to store files, which is a nice way to keep track of things like PGP keys.


¹ It may be broken in the future if usefully sized quantum computers are ever build or if a major mathematical breakthrough is made in prime factorisation—mathematicians have failed to make this breakthrough for some centuries now. If this happens, then I still wouldn’t worry about my personal email: the communications of major world governments, militaries, and corporations will become as vulnerable as mine, and will be a lot more interesting.

² That is to say, there are no direct attacks known to be effective against the ciphers used. There are side channel attacks, which is a fancy way of saying that someone could break your encryption without defeating the mechanism. For example, they could be reading over your shoulder, or they could install malware on your computer that records keystrokes (when you type in passwords), or they could beat you with a $5 wrench until you talk.

Nerdy digression: Star Wars and the “seduction” by the Dark Side
2012. Photo by Hoang Do., At Grapplers Inc.
petter_haggholm

Some people feel that the Emperor’s attempt to turn Luke to the Dark Side in Return of the Jedi is a weak story element, in that there is very little in place to tempt him; that when we have heard of Vader being seduced by the Dark Side of the Force, we should expect something more persuasive. Personally I feel that this misses the point. Certainly and trivially it’s true that “if you go with it, you can win the fight against Vader (your father!) and defeat me, the Emperor (although actually it will give me your victory)” is a rather weak argument. However, that entirely misses the point that it was never about an argument to begin with. Nobody ever said that Vader was persuaded to join the Dark Side. The Emperor was not depicted as a demagogue; his evil was blatant.

Ironically, the point that I think is missed by those who argue that the “seduction” of the Dark Side should have been more persuasive and had a more human element to it is that it was about…well, the Force. It was the Dark Side itself that was supposed to hold an unnatural and harmful attraction—not the course that took you there, not the goals it promised to, or actually did help you reach, but the power in itself: Once tasted, forever will it dominate your destiny. Of course Yoda turned out to be wrong in being quite so absolute, but if we accept him (as the story clearly intends) as wise, then we may infer that his error must ipso facto have been a rare exception.

I think of it more like a metaphysical drug, a psychic super-heroin: Use it once or twice and you’re going to be hooked, not because you enjoy it so much but because it gives you no choice—even if the exposure, as it were, is largely accidental, unwilling, and transient, as Luke’s enraged onslaught at the end of Jedi.

You might argue that this is not clearly stated in the films and that I’m just making it up as a post hoc justification. To this I say—well, maybe, to some degree. Still, regarding (as I do) the original trilogy as the authorative canon, it’s the only interpretation that makes sense to me. You don’t know the power of the Dark Side, Vader intones: I must obey my Master. This was not loyalty, which is still a matter of choice. Rather, the power itself left him no options; he was enslaved to it, using it and under its control.

It also explains the Emperor himself very nicely—twisted and physically distorted, gleefully malicious apparently gratia malice; corrupted, then, by long decades of addiction to the Dark Side. (Need I explicate that I find this a more compelling interpretation than having his face melted by Samuel L. Jackson?)

Speaking of the Emperor, his behaviour lends perhaps the strongest support to my view. I think it is safe to assume that he, within the context of the Star Wars universe, is no fool, and is certainly well versed in the ways of the Force. He has lived with the Dark Side for decades at least, and experienced first-hand whatever effects it has had on him, body and mind. He is, then, pretty well placed to judge its effects on Vader’s mind. Now consider his actions, and his terminal error: He provokes Luke into fighting Vader, apparently expecting Luke’s rage to snare him in the Dark Side. If he did not have good reason to think that this might work, his entire scheme to capture Luke makes no sense. And as he didn’t have anything compelling to tempt or persuade Luke, I submit that he must have expected the intrinsic nature of the Dark Side to do it for him—as his experience had taught him it would.

That’s not the end of it, though, for his behaviour becomes far more foolish on the “psychological view”. The Emperor, seeing Luke caught up in rage, encourages him to kill Vader, and take his father’s place at the Emperor’s side—this while Luke stands over the fallen Vader, who obviously hears every word. Consider this: The Emperor distinctly informs Vader that he’s ready to toss him aside, have him killed, and replace him. But when Luke refuses, and Vader gets back on his feet, the Emperor has no qualms about having Vader by his side again. So: The Emperor demonstrates he’s willing to have Vader killed; Luke refuses to kill his father because he won’t submit and keeps insisting that Vader is not beyond redemption; so the Emperor chooses to torture Vader’s son to death right in front of him, turning his back on this seven-foot cyborg while standing next to a deep shaft into the chasms of the Death Star. Unless the Emperor had strong reason to believe Vader incapable of betraying him, this is beyond foolish: it’s suicide-by-cyborg.

Now, of course it turned out that he was wrong—Luke could and did refuse, and Vader, under these extreme circumstances, proved that though his will had been constrained by the Dark Side of the Force, it had not been utterly subsumed.¹ He was able to make a final choice and redeem himself, though it killed him. (And was this from his injuries, or from the Emperor’s dying lashing-out, or was this because at last he denied himself the addictive substance of the Dark Side on which he had become dependent—and so effectively killed himself?) But unless his mind was constrained, Vader’s killing the Emperor was not a dramatic redemption at all. Of course he might well kill the Emperor, redeemed or not; he had just been betrayed.²

The only way the dramatic climax of the saga becomes a dramatic climax is if you accept that Luke’s resistance was rare, unanticipated, and difficult; and that Vader’s redemption was profound, unprecedented, and hitherto believed impossible by everyone we had met along the way, save Luke only.


Some of you may argue that the psychological view would have given us a better story. Personally I don’t mind a bit of fairy-tale Good versus Evil, so long as it’s not my only fare, but I will not insist that you are wrong. My point is not that a Star Wars version with metaphysical evil is better than a Star Wars version with purely ‘human’ motivations—but rather that judging by the original trilogy, and Jedi in particular, the metaphysical version is the one that was actually made.

You could also argue that if what we saw was a metaphysical conception, it could have been made plainer and it could have been written better. Well, that’s certainly true of all things Star Wars. Nonetheless I disagree with the specific criticism that Jedi is inferior to Revenge of the Sith in that sole aspect of Anakin having a “real temptation” versus the Emperor failing to really tempt Luke with anything. I could even argue that it’s the other way around: By giving Anakin a concrete motivation and casting his apostacy in terms of human motivation, we’re forced to consider the strength and credibility of his sudden turn from “I just want to save my wife” to “alright, I’ll go slaughter some children”, and in terms of human psychology—well, that doesn’t look very plausible to me. Precisely by invoking the mystical corruption of the Dark Side, the original trilogy can at least justifiably ask us to invoke suspension of disbelief.


¹ At this point the Emperor has evidence that the Dark Side was a bit less absolute than he (and everyone else) had hitherto believed, but he didn’t really have time to consider the implications. Seeing Luke resist him, maybe he could have predicted Vader’s redemption, but in any case he didn’t have time.

² It is perhaps a little ironic that the very extreme emotional circumstances at play for Vader are precisely the reason why the “psychological version” would take all the drama out of the climax of the film, by making the choice too easy.

“Evolved brains would be fallible, ergo evolution is epistemically unsound”
2012. Photo by Hoang Do., At Grapplers Inc.
petter_haggholm

Some theologians and apologists (notably, I gather, the fairly famous Alvin Plantinga) hold forth a curious epistemic argument purportedly in favour of their theism. The argument in one form (not due to Plantinga) goes like this: Evolution optimises organisms for survival and gene dispersal, not correct beliefs, which would be favoured only if they enhance the above.

That is, because there’s no telling whether unguided evolution would fashion our cognitive faculties to produce mostly true beliefs, atheists who believe the standard evolutionary story must reserve judgment about whether any of their beliefs produced by these faculties are true. This includes the belief in the evolutionary story. Believing in unguided evolution comes built in with its very own reason not to believe it.

Now, the most obvious problem with this argument is of course that evolutionary theory does give us a reason to suppose that we can arrive at true beliefs, because it is difficult to conceive of any process whereby a tendency toward mostly false beliefs would be beneficial for survival or gene dispersal. I'm sure some scenarios can be dreamed up where fortuitous misconceptions would cause an animal to behave in a manner just as good, or even better, as correctness, and certainly we know of (and science corrects for) some tendencies toward, for instance, false positive errors and other biases, but here we must imagine something both subtler and more pervasive, and in particular a mechanism that accepts sensible input from the exterior world and systematically transforms this input into beliefs that are erroneous and yet more advantageous than the simpler mechanism of apprehending reality…

Still, I don't think that's the argument's worst problem. After all, the assumption of some divine entity provides no more guarantee that your senses are accurate than a naturalistic view! On the contrary: Although it's not a logical proof, I think I have outlined a good reason to think that evolution is in fact likely to produce brains capable of apprehending reality, not perfectly but with at least some fidelity. Assume the existence of an all-powerful being, on the other hand, and that all goes out the window. What grounds have you to suppose, if such a being exists, that the beliefs it chooses to have your brain produce are correct? It is completely arbitrary! The apologist might conceivably argue that his God is a God of truth and so forth, but those are just more of the same arbitrary beliefs. On the assumption that an all-powerful being exists, which can manipulate your senses and beliefs as it sees fit, your are at the utter mercy of its intentions; and its intentions are unknowable, because it can make you believe whatever falsehood it wants, and every “evidence” you might have that your vision of this god is the right one is equally susceptible to (infallible) falsification.

Ultimately, both atheists and theists must assume some fidelity of their senses a priori, whether they wish to admit it or not. Although every epistemology needs its axioms, the naturalistic world view introduces no more than necessary, and people like Plantinga and his fellow admirers of the Argument from Arbitrariness (if you will) would do well to avoid casting stones in glass houses, for once you assume the existence of ultimate beings, everything is arbitrary.

Steam on Linux, coming at last!
2012. Photo by Hoang Do., At Grapplers Inc.
petter_haggholm

Recently, Valve announced that they are working on a Linux version of the Steam client, along with a port of Left 4 Dead 2. Rumours of plans for a Linux version of Steam have floated around since roughly the dawn of time, but now it is official; now it is real.

Reactions are mixed, from gung-ho enthusiasm to RMS-style caution. Personally, I am enthused. This is partly because I am not a free software purist, and partly because I regard this as a win-win scenario.

Cards on the table: I run Steam, and I own games on Steam. Their DRM is not a deal-killer for me. That said, I prefer DRM free software, and I would rather buy games via Good Old Games, who are entirely DRM free. (If a game is available via both services, there is no contest: GOG every time.)

However, I think that this move can only be good for Linux. Even if you never run a Steam game in your life, this is a good thing. One possibility is of course that this effort of Valve's fails, in which case nothing really changes. But consider what happens if they are at all successful:

  1. Currently, there is no significant market for games on Linux, because gamers all run Windows (or, I suppose, OS X); and gamers all run Windows (…) because there are no games for Linux. It's a chicken-and-egg situation; there's no supply because there's no demand, but there can be no demand because there's no supply to demand from. Launch a few AAA titles on Linux and suddenly there will exist a games market. It may thrive or it may fail to thrive, but this kind of effort gives it a real fighting chance.

  2. Games are important. Gaming is a big piece of what computers are used for, and probably the only piece where the average consumer currently has any reason at all to go with Windows over a user-friendly Linux distribution. Having a games market will be good for Linux adoption.

  3. It will be good for indie developers. Even if, initially, only a few AAA games are ported, and only a few AAA developers care about the Linux games market, Steam remains a powerhouse delivery vehicle for games, now to a potentially new market. This should leave a lot of room for indie developers to exploit this new space in a way that cannot currently be done without a good way of reaching consumers.

    As a bonus, I expect indie developers are much better situated to port software, because they don't have massive, hard-to-port codebases to deal with (because indie games are smaller), and because they don't have bleeding-edge graphics and so don't need to worry quite so much about performance; thus a penalty from using a less-efficient cross-platform library, or a performance hit from a less-than-perfect port, is more affordable.

    And I gather that the Humble Linux Bundle proved that Linux users are quite willing to support indies, whose ethos more easily aligns with OSS mentalities than AAA corporations.

    So I regard this as Valve breaking the ice with Steam and an AAA title, whereupon indies will have the powerhouse delivery vehicle of Steam, along with a few larger players, to expand the market. Hopefully more big names will follow.

  4. As this market grows, so will the demand, now backed by real money, for better and better video drivers. The Valve team have already collaborated with Intel to improve OpenGL performance. And big players like Valve are well placed to put some pressure even on giants like NVIDIA and AMD if and when there are problems.

  5. Even if you hate DRM with a burning passion… If a games market is once established in the Linux world, there will be more room for niche players (like Good Old Games) to edge in. It may sound paradoxical to suggest that Valve moving into a virtual monopoly with Steam would improve GOG's position, but I think it may be so. Right now, there's no reason for GOG to target Linux because there is no market, and there are very few games. If a cultural shift of any statistically significant magnitude occurs, then there will be a market (ergo consumers to target), and game developers will be more motivated (and better equipped) to produce Linux versions of games.

We'll see how the ports actually work out, but I for one wish Valve the best of luck and regard the whole thing as a positive development.

“In order to improve, you have to spar with superior opponents”

The oft-repeated saw is that to improve, what you need is to train with people who are better than you are—to swallow your ego and accept that you’ll get beaten in sparring, you’ll have to tap a lot; because you can only learn from people who are better than you (and therefore have something to teach) and in particular, you’ll never learn to defeat skilled opponents without practicing on skilled opponents. There is of course considerable truth to this, and I’m sure it is possible to get very good indeed in a meatgrinder situation where your every training partner from day one is a brown belt and up.

Personally, though, I feel that there is plenty to gain from training with people who aren’t better. Regarded one way, it’s certainly a lot easier to learn offence, and practice new moves that I’ve yet to master, on less experienced opponents with whom I have a greater margin of error. I’ll never pull off a brand new sweep on someone with whom I struggle to keep up to begin with, but with a brand new beginner, I can perhaps get my position and get a few reps in every round. When rolling with people at approximately my own level of skill, I get to practice a more competitive sort of game, because either may credibly “win” and neither is predisposed to play a super defensive, staving-off-inevitable-disaster game—and here those new moves are put to the test. Against superior opponents, well, I certainly get plenty of opportunity to pratice defence

This may be a psychological flaw on my part, but I will be honest and say that sometimes, I don’t feel like I gain anything at all from rolling with people who are better than me by too wide a margin. It’s one thing if I’m constantly forced to play at the edge of my capabilities; that’s fertile ground. When someone shuts down my every attempt before I can even get started, though, I don’t think that really teaches me anything because I get no useful feedback: I can’t tell the difference, then, between “that was a mistake” and “that was a good idea but this guy is just good enough to shut it down anyway”. Then it’s not a learning experience, but mere frustration. (I do my best, when rolling with very new beginners, to remind myself not to create that kind of situation.)

I also think that one should not scoff at the benefits of rolling even with very new people, or much smaller people. Yes, if I outweigh someone by 50 lbs and have 4–5 years of experience to their week and a half, I can probably sweep them in pretty much any direction I choose, but I should be able to make more intelligent use of our training time than that. For one thing, it is a good time to relax, roll without using strength or power, and isolate details, control using the feet only, and that sort of thing. For another, I find that helping people, providing hints, and talking them through those first few rolls can itself be a learning exercise for me as much as for the other person, because it forces me to analyse the situation carefully and isolate and highlight the most important essentials, which is hard to do in the rough-and-tumble of a more even match.

And, of course, it’s good to give back. The only reason I am where I am today is because other people (I would be remiss if I didn’t specifically mention Kabir’s name at least once here) helped me in this fashion, by toning their game down a few notches, give me room to try things, and help me out—and I have a long way to go still, during which I hope to receive more of the same. So of course I want to do as much as I can to provide the same encouragement, help, and guidance to others in the same community or, if you will, family. For all that you go one-on-one at the time when you’re facing a particular opponent, building grapplers is a community effort, and as in many things, the journey is to my mind more important than the destination.

Now I’m off to open mat at GBV (slightly late because I felt moved to write this post) where I will roll with people who may be any combination of better than me, worse than me, and roughly at my level, and I leave confident that either way, I’ll have room to learn.

The Euthyphro Dilemma, illustrated
2012. Photo by Hoang Do., At Grapplers Inc.
petter_haggholm

@Pastorsmallwood: @haggholm I already told you once that is not a problem for me Things are defined as good because God says it in his word ,moral standard

@michaelAsmalls: @Pastorsmallwood @haggholm I'll go ahead and solve your little "dilemma". My moral standards are based off of what God says

The fallacy or incoherency of the above statement was illustrated over two thousand years ago by precisely that famous Dilemma that is here purportedly “solved”, in Plato’s dialogue Εὐθύφρων (Euthuphron or Euthyphro in English). Stated more simply and straightforwardly, consider the following hypothetical:

Suppose that the Christian god (henceforth “God”) exists. Suppose, furthermore, that he commands you to go forth and torture innocent babies to death. Would it be good to do so?

  1. “Yes, if God tells me to do it, it’s good by definition.” This is a logically coherent answer, but problematic in that it implies a morality that does not inherently condemn the torture of infants.

  2. “No; God would never do such a thing, because it is evil.” This is logically incoherent if you take the line that goodness is defined by God’s will: If good is defined by what God says, then he could very well say it and it would by definition be good. God cannot refrain from any action whatever on the grounds that it would be evil, because by definition whatever he does is good. He could torture babies, rape kittens, you name it—if good is defined by God’s will, it’s all good. In this case, the distinction between good and evil is mere caprice on God’s part.

    If you hold that Things are defined as good because God says it, then “God is good” means literally “God does whatever he wants”: nothing else. It is not really a meaningful statement.

    This can be resolved by saying that God would never do such a thing, because it is evil, and if he hypothetically did it, he would be evil. (Therefore, because he is good, it can only be considered hypothetically.) But in that case, God must be good according to some standard of goodness external to what he wants. Then he may be a moral authority (because, we might suppose, he’s been established as being very good), but not the source of morality (after all, it is only logically possible for him to be good in a meaning).

You might wonder how the intrepid Twitter posters from before respond to the Dilemma. The answer is of course that they faithfully, religiously, boldly, and forcefully stick their heads in the sand and refuse to answer at all.

@Pastorsmallwood: @haggholm Greek (geek) philosophy is simply intellectual arguments between those who have rejected God, God is supreme +the bible is truth

@Pastorsmallwood: @haggholm there is no dilemma in my mind God created the world and gave us his word to help to see our sin +show us his Son who alone saves

@michaelAsmalls: @haggholm I'm about truth. Not hypothetical. Find me in the scripture where it says that and then we will discuss

@michaelAsmalls: @haggholm don't make blanket statements.I will not discuss hypotheticals as asinine as the aforementioned of yours.it goes against Gods Word

Greek (geek) philosophy is simply intellectual arguments between those who have rejected God, God is supreme +the bible is truth—is that not marvellous? Explicitly dismiss logic and reasoning if it troubles you; it is better to recite by rote. I cannot help but be reminded of Martin Luther’s admonition that We know that reason is the devil's harlot, and can do nothing but slander and harm all that god says and does.

Even before I outgrew religion I always thought that if God had decided to give me a brain, I should probably use it. I suppose that is why I outgrew faith.


Addendum, after I responded to various “read the Bible it answers all questions and is the truth y’all” statements with a query into whether the man happened to be a parrot or a cassette player:

@Pastorsmallwood: @haggholm more insults , so biblical as Jesus hung on the cross people did the same thing thank you I'm humbled to suffer insults as he did

Even though Jesus’s mythical sacrifice wasn’t that big a deal, comparing my tweet to being crucified and taunted while slowly dying does sound not a little presumptuous and, well, flatly silly.

@michaelAsmalls: @haggholm @Pastorsmallwood we don't have to reason. The Word is not up for debate. It is fact, facts in which we ASSERT.

Do I even need to comment?
