Bigger stakes than that

Walkabout podcast – Bigger stakes than that

Pascal’s Wager is a well-known argument among atheists, and for that matter among evangelists too, even though it appears a lower percentage of those know it by name. It’s a line of superficial reasoning that makes an attempt to logically support theism. In essence, if you believe in a god (most especially one that wields perpetual punishment) but are wrong, and no such being exists, then being wrong has no consequences. But if you don’t believe in such a being and it does exist, you’re screwed six ways from Sunday (especially if such a being frowns on terrible word games.) So, you might as well believe.

This has been torn to shreds before, including my own take, but I now see something that I regrettably missed. And so we return to the argument, and with it even get to see how changing decisions into abstract equations doesn’t give us the functionality we might have been led to believe.

The second biggest flaw in the reasoning (the first being that it assumes a factor that has no support) is that religion is being treated solely as a personal matter; the only person who suffers the consequences is the individual. This kind of two-faced bullshit is wielded all the time, mostly by religious folk whining that their personal rights are being violated every time they’re denied the ability to legislate or control others. There’s little personal about religion; from the simple idea that the devout are urged to “spread the word of god” to the extensive efforts to produce new laws or eradicate old ones, religious motivations likely outnumber all other forms of activism combined, at least in this country, and most assuredly in theocratic regimes like half of the middle east. So the consequences of being wrong do not revolve solely around personal salvation, but the effect on everyone who has ever been influenced by religious concepts.

So, I ask the faithful, what if you’re wrong? What exactly does this mean?

1. That you have spent some (probably large) portion of your life judging actions on a meaningless concept, including all stress over what god might disapprove of and how to conduct yourself in any given situation;

2. That all confidence in divine authority and even mankind’s exalted status was entirely misplaced, a huge delusion. Any and all preaching and advice and suggestions and even disapproving looks stemmed only from ego, as did all beliefs in human importance in the cosmos;

3. That the pressures placed upon everyone who engaged in behavior not approved by faith were all pointless. This includes everyone from the masturbating youth to the unwed pregnant teen to the family of a suicide victim, who not only had to consider that their loved one was in perpetual torment, but that their own failures may have contributed;

4. That every instance of gay beatings, and verbal assaults outside abortion clinics, and even every last guilt trip over the right people to marry and the right way to raise kids, was all stupid;

5. That a significant portion of the money donated to churches went to self-perpetuating scams rather than anyplace it might have made a real difference; you know, achieving good results;

6. That every politician who garnered support by playing the religious card was only trolling the rubes, when they could have been concentrating on campaign efforts that would produce positive change;

7. That everyone who died from AIDS and STDs and unplanned pregnancies, solely because they were told condoms were bad, never had to die;

8. That everyone who has died in a holy war, or witch hunt, or religious suicide attack, or even over medical restrictions and withheld care due to “faith,” also died for no reason whatsoever. Life being so sacred to religious folk, you know…;

9. That every terrorist cell and fanatical regime which recruited followers based on ideas of destiny and ultimate rewards would have had to find another way of convincing the pawns. Speculation over the relative usefulness of other motivations is left as an exercise.

I’ll be kind and stop here, but I suspect it’s effectively demonstrated that this could go on for pages. Reducing the entire concept down to the idea of a single point of consequence shows that Pascal (and everyone who resorts to the wager) didn’t understand how flawed it is to try and apply binary decisions to real world consequences. Though it’s possible that he actually did, and formed the conditions of his wager because it produced the answer he wanted to arrive at…

There are undoubtedly those who would argue that their faith really is private, and that they engage in a “live and let live” attitude towards others, avoiding preaching and advising and even internal judging – that gets one off the hook for the worst of it, but not the personal consequences of spending one’s life in pursuit of unfulfillable goals. Not to mention that this probably accounts for less than 0.5% of religious folk. Yet, even this fails to establish innocence, since it remains a self-centered defense; claiming that I did not commit any crimes doesn’t absolve me of criminal negligence when I witness crime and do nothing about it. Simply by admitting to some form of faith, anyone has given their tacit support of that faith, lending a legitimacy to the entire ideology, and this is worsened when they fail to correct any of the bad practices by others. The christian who favors loving everyone as brothers and the christian who gives money to legislate against homosexuality are basing their decisions not just on the same book, but the same concept; that their authority is both beyond evidence and completely rational, the curious double-standard of religious devotion (actually, it’s more likely just opportunistic indulgence of personal desires, but that’s another post…) While there is never a shortage of muslims who claim islam is not about violence, every time there’s a violent act in the name of islam, somehow the violence goes on – we don’t see any corrective actions, just protests of innocence. I can tell you, if I find myself bleeding my life out from an attack by a religious fanatic, knowing that my attacker wasn’t truly religious will make it all much better, I’m sure.

Now, can we effectively weigh the two original potentials of the wager against one another? We have the religious view, which promises eternal torment if one is wrong, and the secular view, which produces a variable (yet vast) collection of social ills. Did you catch the subtle change in wording there? I hope so, because the idea of god’s retribution comes solely from scripture that is wildly inaccurate about known facts, repeatedly self-contradictory, and doesn’t even make sense by any logical process – eternal punishment is a threat, not a practice that could achieve a damn thing at all (thank you, I’m here all week.) Confidence in any claims made by scripture doesn’t come from the accuracy demonstrated – it’s entirely wishful. While the consequences of acting on religious authority are plainly visible and easily measured – literally, infinitely more demonstrated than any metaphysical claim. And they remain detrimental regardless of whether any god exists or not. Trying to compare these as if they had an equal standing is dishonest to a pathological level.

Worse, the truly ugly aspect of all this is that religion is widely, repeatedly claimed to be a force for good, yet that list up there doesn’t really demonstrate it at all, does it? In fact, more good would have been accomplished without the interference of religion in most of those cases – I’m weird this way, but I find it hard to look favorably on anyone pursuing their personal salvation at the expense of others. So we can see that “right or wrong” is not really a productive strategy, when one could substitute “good or bad” and receive real, useful guidance on how to make worthwhile decisions and contributions – ones that anyone would have every right to feel proud of as well. This does, of course, mean that someone would have to know a functional method of determining good, such as the incredibly difficult task of equating it with benefit.

I can’t ignore the argument that faith is solely about belief, and with faith comes salvation – this means that good acts don’t really matter because it’s not about how one acts, just how they think. Yes, this really is claimed, surprisingly often, apparently by people who have somehow failed to notice that scripture is brimming with long lists of proscribed actions, as well as the often-bloodthirsty consequences of violating them. Ignoring for the moment the neurosis of an omnipotent being who demands ego-stroking on penalty of torture, the implication is that even the most heinous crimes don’t count if one’s heart is in the right place, which takes religion very distinctly out of the discussion whenever morality is brought up, since morality deals solely with how one treats others. And even if we accept this pathetic argument, it would mean that the faithful have no purpose nor provocation to try and affect others in any way – their efforts to promote their beliefs and authority have nothing whatsoever to do with personal faith as a goal. Obviously, not a whole lot of religious folk are devoted to that argument even when promoting it.

It’s hard to argue that we as a species do not need a little more clarity in purpose, some method of reducing the selfish, defensive tendencies we are prone to – in other words, some stronger moral guidance. I have little doubt that not only was this the intention of every last person who resorted to the “ultimate authority” angle that eventually became every religion on earth, it’s the underlying goal of many who use it now (I was going to say “nearly everyone” before I realized that no small percentage of people use religion entirely for manipulation.) But as was just demonstrated above, good intentions don’t justify harmful actions in anyone’s sense of community, and the ridiculous machinations of religion open the door for countless forms of abuse and self-indulgent selectivity – producing exactly the opposite effect in too many cases. This becomes absolutely astounding when one realizes that morality is not a hard concept to grasp, certainly in no need of idiotic stories about original sin and following false idols. Even in those few circumstances where determining the best action is hard or subjective, one can easily realize that inaction is much better than any kind of detrimental undertaking. And this demonstrates far more logical thought than any hackneyed “wager,” which serves only to justify a pre-existing standpoint. So why wager when we already have a sure thing to pursue?

Frustrations, part 10

We’ve had a couple of bluebird nest boxes in the yard for the past two years, attracting occupants each spring, and of course this means I’m attempting to get some decent images. What I’m most after are the newly emerged fledglings, the young whippersnappers just leaving the nest, but while waiting I try for feeding shots as well.

The folks are a tad shy about me looming over their shoulder when feeding – according to a biologist, this is something about not revealing where their young are, but that’s nonsense, since I was the one who put up the nest box, and I’ve told the bluebirds that. But because they’re still neurotic about it, I resort to remote camera work, as seen here.

BluebirdRig
The camera doesn’t have to be very far away, and my focal length was only 230mm for the following images. You can see the flash for supplemental light (mostly trying to throw some into the box,) and the reflector on the ground which was contributing only when the sun dodged from behind the clouds, which wasn’t often (held against the gusting wind by the water jug.) I had a remote shutter release on a long cord and sat six meters away behind another patch of pampas grass out of sight to the right. The fuzzy bunch of weeds to the right of the nest box, by the way, is a new patch of dog fennel, which provided so many photo subjects last year that it’s being encouraged again this year.

OpenWideI had the flash unit dialed up a little too high for the first shots, like that seen here, and eventually changed the camera angle to see if I could get the adults and young framed better. There’s a bit of folklore that animals are scared of a camera flash going off, and I’m happy to tell you that in my experience this is total nonsense. If you think about it, most animals have seen thunderstorms in their lives, and a brief flash of light doesn’t appear on their list of mortal dangers. I’ve seen some give a quick start in surprise, only on the first flash, but none that have ever appeared negatively affected – I’m even skeptical that species which are sensitive to light, such as sea turtles and cephalopods, could possibly be affected by a brief flash, because sunlight (which is sustained and many times brighter) would permanently blind them. The bluebirds paid more attention to the shutter noise, and that wasn’t much, since I have 36 images of feeding in a little over an hour – they weren’t exactly spooked. And with most songbirds, the feeding instinct is so high that there’s little that makes them hesitate too long, though it still isn’t worth harassing them to find out what their limits are.

FindMyOwnFoodI knew we were getting close to fledging time, since I’d peeked in on the young every few days to see their development. Last year I had missed it when it occurred, and I was determined to try and get it this year. The young were also giving some strong indicators, including fairly regular peeks from the box, giving the impression of an elderly woman noting that the new neighbors have small children. In conditions like this the flash angle is important, because the depth of the box can throw shadows across the sprogs within, so I’d repositioned the flash to be high above the camera but in the same line – note how the shadow of the roof just misses the box opening (the sun actually sits behind the north-facing box, which I believe makes the adults happier but isn’t exactly a bonus to photography.)

Alas, I had a photo student yesterday morning and left to meet with them for a couple of hours. On my return, I sat out and observed the nest box for a while to gauge the activity, which was suspiciously nonexistent; eventually I opened it to check, and yes, it was quite empty. While I was away the fledglings had bailed not just the box, but the entire yard, and were nowhere to be seen, though I spotted the male on the overhead wires twice. My attempts to see where he might have led the offspring were in vain. So much for that photographic resolve.

ImpatientLast year we’d witnessed two different broods in the boxes, so it’s possible I’ll get another chance this year – I’ll just have to keep my eye on them (and keep encouraging the insects in the yard.) In the meantime, I’ll close with the first image I got, while I was still setting up the equipment. I glanced up from focusing the camera to find the female waiting impatiently for me to finish so she could stuff the kids – she was on the stump just to the right of the box. I twitched the camera around and fired off a frame before she could bolt, not even sure if the settings were solid, but I can’t complain about the image at all. And just FYI, we didn’t do that butcher job on the stump, which had been a thick variety of cedar bush. Inexperienced help which misinterpreted the landlord’s instructions had treated it like the pampas grass, which really does need cutting back to practically nothing each winter; the grass grows back, the bush was a goner. If I was more ambitious, I’d try to carve something creative out of it, but right now it serves as a nest box support just fine.

Macro photography, part seven

FlatPanel2
I mentioned in an earlier post about experimenting with a new method of lighting macro subjects, so now we’ll take a close look at it. One of the chief pursuits of photographers is getting the light just right, which is more involved than one might suspect. Stopping action and camera shake requires a fast shutter speed, especially at high magnifications, so a lot of light is needed, but if it’s too bright it produces a spotlight effect, with overblown reflections and deep shadows (made worse by the simple fact that photography always produces more contrast than we see with our eyes.) Enter the flash diffuser, which scatters light from a broader area, reducing the reflected highlights and throwing more light into the shadows, reducing contrast. In a portrait studio, this is usually accomplished with white umbrellas or a large unit with a thin fabric panel called a softbox. And the same can be used for macro work, but in the field you generally want something that stays with the camera and repositions as you do, so all sorts of tricks are used to produce the ideal lighting system. Alex Wild talks a little about it in his Compound Eye blog at Scientific American, with a couple of linked examples from others; now here’s one of my variations.

FP38Sunpak makes a flat-panel flash unit, the FP38, which uses four small flash tubes and a large diffusing panel to produce a softbox effect. It’s not terribly large, lighter than my workhorse Metz 44 MZ-3i, and has some nice options like variable positioning and a built-in slave trigger (meaning it will fire simultaneously with another flash by detecting the light produced by the other unit, so it doesn’t even have to be mounted on a camera.) The mount has the standard two-contact hot shoe, but since the panel unit itself is only pinched by the mount, the triggering signal is passed from the hot shoe to the panel by a PC sync cord (meaning you can also connect directly to the camera the same way.) PC syncs are notorious for developing poor contact, so I opened the panel unit and soldered in a 2.5mm mono plug socket instead, which most of my flash units will take now. Now, in an ideal world a macro flash unit should be able to tilt over top of the subject, since we find light from overhead is much more natural-looking – this was something neither Sunpak’s mount nor my current flash bracket could do; at the same time, I found the light was still a bit harsh for my purposes. So I added a new reflecting/diffusing panel.

FPDiffuser
It’s pretty simple: just three pieces of matboard, with aluminum foil glued inside to increase the reflectivity, and a piece of thin white fabric as a diffuser for the light passing through (what you want is something about like tissue paper, transparent but not completely so.) It was measured to extend over the entire light-emitting portion of the FP38, and attached with three pieces of hook-n-loop (Velcro.) In my image, you’re looking through the area where it attaches to the flash unit – it’s upside down here. With some creative angles from the flash bracket, the diffusing sheet ends up being perpendicular to the subject, more or less.

FlatPanel1
While the FP38 remains vertical (it’s aligned with the back edge of the diffuser in this image,) the cloth panel angles forward, producing light that is partly from above and partly in front of the subject, which gives a good view to the camera and still looks natural. It does mean that the whole unit sometimes looms above the subject, which can send shy insects under cover, and in tight situations it can interfere with the very plant that supports the target species. Yet this would be true of any diffuser save for a studio light on a high stand, something few people can make work in the field, so it’s just something that one copes with. The added benefits overcome the occasional detriment.

I’m going to sidetrack slightly here while the image is not too far away. The lens I’m using (yes, that’s me) is my old Sigma 28-105 f2.8-4; the automatic aperture had died many years ago. I opened it up, removed the aperture motor, and manually set the aperture to about f16. Reversed, it can produce quite high magnifications and some pretty damn good results, at much less than the cost of the only lens I know that can do the same, the Canon MP-E 65mm. It does mean that the viewfinder image is quite dark, and focus is fixed for any given focal length, but the zoom still works and this affects focus and working distance simultaneously (same with the MP-E,) so there are options to work with. Also visible is the large eyecup I added to the camera, which aids greatly when using this lens (especially with eyeglasses that allow glare to come in from the sides) and just in bright sunlight. On top of the camera is a homemade device that drops the voltage of flash units down to a safe level (I used the design here.) Some older flash units throw a lot of voltage through the hot shoe, and the 300D/Digital Rebel, among others, is sensitive to this, so the gizmo there allows me to use the Sunpak FP38 or a Capro RL80 ring flash without frying the camera.

So, how well does it work? Let’s start with the effect on the toughest of subjects, something highly reflective:

FPEffect1
Instead of a bright spotlight reflection, what is produced is a “hazy sky” broad effect throwing good light around. In this tight crop, you can see the distinctive shape of the unit’s light itself, with the main panel producing the “window panes” to the left, from its four flash tubes, and the diffuser producing the pattern to the top and right of the reflection. Perhaps drawing attention to it in this manner makes it seem weird, and the effect may not be for everyone, but bear in mind this is a set of conditions rarely encountered, chosen just to show the effect – also note how well controlled the contrast and shadows are. A more typical tough subject is a closeup of a jumping spider, with their highly reflective eyes, and the effect is quite acceptable (to me, anyway – mileage varies) in such a case:

FPEffect2
Notice how detail on the side of the ‘head’ (cephalothorax) to the right, and under the legs, is still clearly visible, even though in shadow, and that nothing is harsh. My subject here measures about 3mm wide, and is perched on a blade of grass.

CricketComparisonPerhaps this displays better with a side-by-side comparison of the same species of cricket – direct flash on top, and the flat panel with diffuser on the bottom. Shiny black subjects are the hardest to achieve good lighting of and virtually need a diffuser of some kind, for reasons shown here – pay attention to the shadows too. The color is better, the textures more apparent, and even the implied conditions much more mellow – the top image communicates searing sunlight, high noon in the desert. Diffuse light is just a more pleasant result. Further samples can be found attached to some of the past several posts with arthropod images, for example here and here (previously linked above.) The daisy is not taken with this rig (instead a softened offset flash,) while all of the spiders and mantises have been, and the water droplet image is natural near-overcast light. The diffuser even helps a little with the problem of the background dropping into darkness, because it scatters more light around, but it’s still short-range and won’t correct the problem with flash macro and a background lit by natural light (basically, not appearing lit at all because of the small aperture and fast shutter speed.) To correct that, you either need a closer background or a second lighting unit to illuminate it separately at its distance.

OneRingToRueThemAllI’ll also take a moment to throw out a comparison with the ring flash. This is a flash tube that surrounds the lens, which produces almost no shadows – this is sometimes a bad thing, because it’s the shadows that give shape and depth; you just don’t want them too dark. And with reflective subjects, the effect is much more disturbing than the “window pane” shown above.

There are some caveats to the FP38 and diffuser rig, too. Recharge time is a little slow, meaning no chance of snapping off two shots in quick succession, and it has a pretty hard power draw – too many frames and the batteries can start to heat up, dropping their response. There is no ‘charged’ beep and no way to vary power output (I got spoiled with the Metz.) It can take an AC power source, but my one set of tests with that produced some indication of either shorting or overamping, something I have not pinned down yet. The size of the panel limits the kind of bags it can be stuffed within, but at least it’s not too thick. I stupidly did not make my (easily detached) diffuser capable of folding flat, where it could have tucked alongside the flash unit smartly – that modification will be done soon. Sunpak claims that the unit can be used on a mini-tripod, but the unit being offset so far to the side of the mount means it would tip over most mini-tripods, and it cannot be used centered over the shoe mount in any other application (without modification anyway.) Yet, for macro work it’s a very inexpensive little unit, and the slave function works great. It’s far from being my only lighting option, but it’s a nice addition once I got it producing the light I liked.

I suppose you find that funny

So, I met a student in the local botanical garden this morning, and afterward took a couple of passes through the garden to see what there was to chase. I have a post in draft form, coming soon, that’s going to have a few images of jumping spiders, plus a whole collection of other recent pics – they’re primarily what I’ve been seeing lately. Thus, if anything, I’d pass on jumping spiders in favor of something else.

SmugJumper
Naturally, I glance down and find my friend here, dancing around idly on the flash unit, meaning I wouldn’t be able to use the flash for any images, so no smaller aperture for higher depth-of-field. She was cooperative enough to stay put as I disconnected the camera from the flash bracket, and despite the poor natural light, I still got one frame that was pretty sharp, wide open at f4, while holding the bracket in my left hand (meaning a double-handheld shot.) Once I’d coaxed her onto the rosemary nearby, she vanished completely, so no chances for further compositions.

Did the spider know that she was making things difficult? Was I being mocked? Oh, I have no doubts at all – note the impish look on her face…

For a given value

A recent post over at Scientific American brings up an interesting question, especially to those who pursue critical thinking: what does rational actually mean? We use this word all of the time, perhaps without realizing how subjective it is; few people ever think they’re being irrational themselves, while others would be quick to disagree with their self-assessment. But unlike some subjective terms, like happy, rational is often used in a sense that requires some agreement on the definition and/or functionality, so it bears examination.

We’ll start, of course, with Merriam Webster:

1 a : having reason or understanding
   b : relating to, based on, or agreeable to reason : reasonable <a rational explanation> <rational behavior>

… which ends up sending us to find out about reason, where if we skip the circular references back to rational we have:

c : a sufficient ground of explanation or of logical defense; especially : something (as a principle or law) that supports a conclusion or explains a fact <the reasons behind her client’s action>

So the bit about the logical defense is what brings us the closest to what we typically mean when we say rational. A rational argument should be logical – but, there are problems with that. In the article, the writer indicates that economists use a version of rational that requires only logical coherence, and not reason – if we were attempting to understand what this word actually means we’ve just collapsed in a circle of contradictory and illogical definitions. What has been missed so far is that rational often implies, if not outright requiring, the minimizing of adverse effect. As I mentioned in another post, one solution to food shortages is to kill off excess population; this is logical, but not rational. And we start to get an idea of the things that bear a significant influence on our decisions, and the very definition of rational.

The emotional reaction to any given situation or decision determines most of what we consider rational. As Spock repeatedly observed (sepulchrally,) we emotional humans keep doing illogical things. And yet, this all depends on how one defines logical as well (don’t get discouraged – this rabbit-hole does have an end, but the descent displays all the interesting bits.) Logical does not simply mean that the line of reasoning follows a demonstrable consequential path, A leads to B leads to C, but often that there is a particular purpose in mind. The solution to the food shortage above is unacceptable because it has the same consequence of the food shortage – death of a number of people – so it defeats the purpose, which is to avoid death as much as possible; the food shortage is just a factor which is denying this purpose. And the purpose is defined by our desires; empathy and survival as a species and such like that.

Then there’s another stumbling block: our logic is limited by our experience. In fact, it is formed solely by the patterns we have observed, the matrix of cause-and-effect that we build from birth. If we were to use the word in its usual sense, logically there is only one outcome possible to any situation regardless: that which will happen. But without omniscience, what we can ‘logically’ deduce is only what we think will happen based on past experience, which works pretty well but occasionally is wrong (leading to a new experience and new expectations.) So our logic is only as good as our data – and filtered through what we want to accomplish.

This is significant. What do we want to accomplish, and why? Remember that we, as a species, developed the vast majority of the traits we have because they contributed to our survival – they simply worked better in the game of probabilities that is genetic variation. Using the same food shortage example, we are concerned with the deaths of others because of our social tendencies, the drive that keeps us working in a cooperative tribe which produces more benefits than individualism does. So our logic is perpetually affected by what we might feel are important goals or outlooks – it cannot be the functional, mathematical process we often imagine it to be because we ourselves do not function in that manner. This means reason, outside of abstract philosophy, revolves around fulfilling an evolutionary ‘goal.’

Now the tricky bit. There are often multiple ways to fulfill these goals – some not so functional. The article actually has a comparison between heroin addiction and bowling, claiming that they both fulfill the concept of “self-interested utility maximization.” This misses a couple of points, the most glaring being that this can describe every last thing that we do, so they’ve done more for defining “life” than dealing with the concept of rational. Since virtually nobody finds drug addiction and mildly competitive past-times to be even vaguely analogous, and in fact often have very strong views on addictions, obviously something more is at work – especially when addiction frequently fits the definition of irrational. Without attempting to delve too deeply into the functions of addiction, the biggest difference might be the comparative weights of immediate gratification (the euphoria of psychoactive drugs) versus the consequences of negative physical, social, and economic impact. Any individual that rates the gratification higher in importance than the consequences will seem irrational to everyone who weighs these exactly the opposite. On the other hand, bowling produces far less of any negative consequences, so gratification is weighed against practically nothing and can win the decision easily.

So now let’s look at a topic that dances on either side of the rational/irrational line, depending entirely on who is asked: psychic predictions or clairvoyance. Those convinced of the existence of psychic abilities cite the numerous examples where it has been demonstrated, while those convinced of the non-existence cite the number of examples where it has failed, and the ability for the positive evidence to be caused by more than one source. Neither one can be called irrational/illogical/unreasoning by themselves; instead, views favoring one side or another place different values upon, for instance, anecdotal accounts or rigorous laboratory tests. Those values are not necessarily obtained logically; they can just as easily (probably more so) be determined by desire, and past experience, and even indulgence. A person whose parents had a negative view of scientists may possess a distinctive distrust of scientific evidence, solely because they respect their parents. This can contribute to the values assigned to the evidence of The Amazing Schmendrake’s clairvoyance.

[A small aside for a bit of perspective (I would have said logic but I’ve already thrown the definition into question, which is one of the many traps of too much philosophy): evidence is, and can only be, for one thing, which is whatever caused it. The same parlor tricks Schmendrake uses cannot be evidence for and against clairvoyance – they must be one or the other. The question is, are we interpreting the evidence correctly? This question underlies the entirety of the observation-to-conclusion process.]

Returning to the personal valuation of evidence, it is worth noting that few people ever recognize these influences, instead convinced that the whole process demonstrates rationality. While this does indicate that rational is almost certainly a misleading term, if not totally corrupt, that does not mean that a logical (ahem) argument in rebuttal cannot have an effect; people are still able to compare stronger and weaker arguments, and recognize flaws if they are presented in an effective manner. We can’t even talk about whether they’re willing to see such flaws, because they are, provided the counterargument addresses their internal valuations adequately (finding these is, naturally, the challenge.) Rational is an abstract superlative that cannot be demonstrated, like good or bad – no argument will ever be shown to be perfectly rational. But we can use benefit and detriment in place of good and bad, or simply demonstrate that one choice is better than another, and we can do the same for every place we might be inclined to use rational; that argument may be good, but this argument is better. And in doing so, we avoid trying to assign negative labels to an argument (or the person promoting it) to concentrate only on being more convincing.

*     *     *     *     *

There’s a small consideration that it probably wouldn’t hurt to bear in mind, on top of all this. For decisions of importance, how might one go about determining what goals are rational or, taking our cue from all that above, simply better? While our feelings about cooperation and empathy are evolved towards a particular benefit and underlie much of what we consider reason, we also have feelings about competition, the individualistic desire to appear better than others when it comes to sexual selection and leadership. This often translates over in many other areas, sports and career among the most prominent (sports probably wouldn’t even exist without this influence.) And while these evolved drives have their beneficial functions, they cannot be applied to every situation; sometimes they’re badly misplaced. The person who is too involved in cooperative, social interactions can place themselves at risk, especially when dealing with someone who views the interaction as competitive – I know it’s a hackneyed example, but think of trusting everything an auto dealer tells us. Alternately, competition has only specific areas where it provides benefit – elsewhere it manifests as pure ego, making us believe individual accomplishments are important. Such drives lie within much of our career actions, many corporate attitudes, and virtually everything regarding marketing. There is extremely limited benefit to the individual from pursuing ever higher income, and absolutely none to the species as a whole – it’s quite easy to demonstrate that this is remarkably detrimental instead. The corrupt concept of Social Darwinism implies that the individual demonstrates their ‘fitness’ in competition, but to what end? Evolution is a function of survival and reproduction, but it takes place in populations, not individuals – individual selection is only successful when it benefits the species as a whole. And let’s not forget that the process leads to extinction as well – what doesn’t work gets weeded out. When the trait of misplaced ego results in both overcompetitiveness and vast resource exploitation, it’s hard to see how this is a structure to survive the long run.

The message that seems to come forth is that many of our decisions, far from being rational, are colored by simple desires – and that these sometimes (perhaps quite often) can be mistaken or misplaced. The nice part about our species is how well we can recognize such influences with our fancy brains – when we put them to work being objective, rather than with efforts to justify indulgences.

Tech support

For everyone who came here (or to the main site) in the past two days and got blocked out, I apologize, on behalf of my hosting provider GoDaddy who will never do so. It remains unclear what exactly happened, but suffice to say they were woefully unprepared for it, which is pretty inexcusable from a major hosting service.

Worst of all was their Tech Support, which was slow to respond and completely clueless when they did. I’ve hosted this site for 10 years now and, while not a webmaster in any usual sense, understand file systems and permissions, FTP processes, and DNS and mail servers. When I contacted them, I gave them everything they needed to know, what I’d already checked and where I was finding issues (for instance, that I was blocked out of their own clumsy FTP tools, and my external FTP program had come up with a blank directory tree instead of the 185Mb of content that should have been there.) Tech Support took nearly a day to get back to me and ask for my PIN “before they could proceed,” and when receiving this, took another several hours to say, “It’s because you have nothing in your directory.” Yes, “echo” has a different meaning in IP services, guys…

Nonetheless (because, seriously, you can’t get any less helpful than this,) they gave me their boilerplate directions to go find their directory archive to restore the tree to an earlier point, something that is necessary because their interface design is, shall we say, pathetic. The archive gave every indication that it didn’t exist as well, so I re-uploaded all of my content – thankfully I have a reasonably fast connection – to meet with the exact same issues.

Now, GoDaddy did actually have my site mirrored on their servers, as demonstrated by it being active now without changes. They just never bothered telling me what was going on through their tech support, made me waste a serious amount of time trying to correct their issue, and took their own sweet time fixing it themselves. Even their vague “we’re doing maintenance” notice, not to be found anywhere on their site but mailed directly, listed their “outage” times as starting seven hours after my site was down and ending 14 hours before my site was actually restored – that tells me that this was not maintenance and that they had no control over whatever happened.

So if/when it happens again, be patient – I’m working on my end to correct the issue.

Drama

We’ll start with the artsy-fartsy one.

EdgeOn
This came from a patch of wild daisies down near the river, many of which served as eyries for crab spiders (I think I’m mixing metaphors without goggles again) that were making a serious dent on the hymenoptera population in the area – every one I found either had a meal in chelicerae, or soon obtained one. They tended to be shy and sidled from the center of the bloom to the edges and underneath as I approached, meaning some of my shots were taken from flat on the ground aiming against the sky as the spiders tried to hide. But in the middle of it all, I just nabbed a quick perspective from a sitting position.

Back home, I found another crab spider occupying the salvia plant I’ve had for a while now, which has undergone two transplantings – the first almost killed it, but it recovered nicely with the second and is now blooming madly.

SalviaCrab
This guy was hiding not so much from me, but from the collection of small red ants that had taken over the stalk for a short while – don’t ask me what defines the difference between food sources and deadly threats to spiders, because I don’t know, but the spider certainly wasn’t viewing the ants as an easy meal. Possibly it was idea that capturing one would have triggered a defensive odor that brought others swarming to attack.

I’ve mentioned that some images are vastly improved by choosing the right angle to shoot from, and this illustrates one example. On the same bushes housing the mantids have been a few assassin bugs, and typically what you might see in examining the bush would be something like this:

SatelliteView
But a little effort in maneuvering and positioning can change the image dramatically, and even produce a faux look of despair from the captured housefly:

HelpMe
There’s so much at work here: the raindrop that produced a reflection from the flash, making the compound eyes appear to have a frantic wide-eyed look; the open-mouthed illusion; the fact that we never see flies not perched on their hexapod of legs; and even the peculiar angle of the head. All of it produces something we expect to see from people, not from insects, and makes us relate a bit more to what is strictly an imaginary emotion. It helps illustrate how we can be manipulated by inherent social reactions.

And a tighter crop of the same image, because I’m pleased with the detail captured:

If you see a goatee and perhaps even a tongue, shame on you – you’re not detaching yourself in a professional manner. But now you can’t unsee it, can you? ;-)

To the rescue! Or, not…

I think most people know that there are certain kinds of fires that you don’t throw water on to extinguish, primarily grease, oil, gasoline, and electrical. In such cases, water is simply going to make matters much worse, either by splashing and floating the burning substances to disperse in a wider range, or by producing greater damage to equipment and creating the potential for electrocution. For this knowledge, we can thank numerous organized campaigns that drilled the information into our heads, usually at a young age, but what this highlights is that some things that we might do in the belief that they will improve a situation end up doing more harm than taking no action at all. This really cannot be emphasized enough; intentions must be married to actions that produce a positive result.

While this might seem obvious, that’s what becomes so disturbing about so many things we come across. People for the Ethical Treatment of Animals (PETA,) for example, has a fairly inarguable goal: to prevent animals from being treated poorly. Unfortunately, this goal is used as supposed justification for activities running from pretentious and condescending ads to pointless vandalism; the end result is a widespread public view that animal activism belongs to the fringe elements. Having worked at a humane society, I got to see this firsthand; while we never engaged in any kind of sensationalist media ploys or extremism, we still received an attitude of “guilt by association” from far too many people, and were at times considered to be radicals.

Feminism, as I’ve touched on briefly before, is another example. Unable (or unwilling) to differentiate between legitimate sexual inequalities and fantastic patriarchal conspiracies, feminism generates a “women with emotional issues” dismissal among a significant percentage of our population – which, all too often, is then considered by feminists as proof they were correct about the conspiracies; the polarization within the topic probably exceeds even that of politics, since politicians are not one-tenth as likely to be called potential rapists routinely.

And, the list goes on: the anti-vaccination movement, abstinence-only education, the anti-GMO crowd, Greenpeace… superficially, all displaying noble goals that could be said to benefit the entire human race. The part that gets missed far too often, however, is that there is a difference between the emotional and practical aspect – the intention and the execution. Despite stupid proverbs about paving, good intentions are something we really could encourage more in any society (as opposed to the idea that we’re all in competition with one another,) but what makes any difference at all isn’t the intentions within our heads; it’s the ways they translate to real-world differences. The question that should be asked before any kind of social activism (and most especially any action linked therewith) is, “How is this going to improve things?”

We’ve all seen videos of Greenpeace boats harassing whaling ships or trying to block waste dumping in the ocean. And I think it’s safe to say that we’ve never seen any of those targeted ships give up and go home. The only thing that’s going to stop industrially-sourced damage is legislation – the threat of legal consequences that hits someone much harder in the pocket than doing business in an environmentally conscious manner. Someone can argue that Greenpeace’s actions are “raising awareness,” but such a statement should be supportable by solid facts, not just the belief that it could work. And at the same time, the “awareness” that is raised should be predominantly positive as well – there really is such a thing as bad publicity.

With many of these subjects, the underlying motivation is emotional: compassion (over the plight of children or animals,) frustration (over the ills provoked by a capitalist outlook,) and even, perhaps mostly, ego (I am the one who’s going to make a difference!) Emotions are good, in that they motivate us towards choices and actions, but they are misleading in many ways too – it’s possible to appease an emotional desire without in any way improving something, meaning all that the emotion produced was self-indulgence, a placebo if you will. Without asserting the rational processes in ourselves to examine consequences and results, we may start to believe that we did something useful when our actions were simply a “knee-jerk” response – this is what underlies drug addiction and standing on streetcorners with signs bearing biblical quotes.

I’ve written about genetically modified organisms before (otherwise known as “GMO”) and this is an extension of the “chemicals are bad” meme that started with Rachel Carson’s book Silent Spring and the birth of the environmental movement. It soon became the demonization of “processed food” and the belief that all corporations were completely dismissive of negative consequences. Most of this, however, is the result of people who have reduced their thinking processes (if it can even be called that) down to pre-school levels of “good” and “bad.” Processing food does not destroy all nutritional value, and chemicals are not all detrimental to our health. My statement above may be taken to mean that I think the environmental movement was a bad idea, but that’s just an ironic demonstration of how the point is entirely missed: no such all-encompassing term such as environmentalism can be branded with a binary “good/bad” label, and the functionality of environmentalism comes from careful consideration of the consequences of any action. Arguments go on to this day regarding the effects of DDT – it’s incredibly damaging to the environment; no no, it could have eradicated malaria if we hadn’t banned it! Looking at the facts, DDT is less of an environmental hazard than mercury, but it does remain in soil and water for long periods of time, and does produce serious negative effects. The reasoned approach is to examine the negative and positive effects (which every practice has) and know how to compare them to determine an acceptable outcome. Instead, what we often see are people seizing onto whatever factoid they can use to support their existing standpoint and wielding that as a bludgeon – coerced by their emotions away from the most functional aspect of our species, the ability to think rationally. Or, we see the unwarranted extrapolation of any given fact towards the extremes, resulting in people believing that chopping up fruit or heating vegetables turns them into worthless dust (which, even if it did, does not translate into being bad for health either.)

There is another hazard that goes along with this kind of thinking: someone else will recognize the lack of critical distinction and exploit it. The vast majority of the ‘health food’ movement revolves around shameless manipulation of the facts, when facts are even involved; the movement is rife with things that have no basis in reality. Those that believe that “organic” means “healthy” are suckered into paying premium prices for foods with a meaningless label: “organic” has no regulated definition in regards to food labeling, at least in the US (I cannot vouch for other countries.) Meanwhile, poison ivy also fits in with just about everyone’s definition of “organic,” which shows the problem with resorting to simplified thinking. A pesticide that washes off and isn’t retained in soil has not harmed anyone’s vegetables in any way, and some pesticides don’t even have a negative effect on humans anyway. Their use results in higher crop yields, which means lower prices and more efficient use of land and resources. Alternately, some pesticides really can do a lot of damage – the word “pesticide” does not tell us anything other than “intended to reduce insect damage.”

But then there are the times when simplified thinking completely fucks things up. The catholic proscriptions against condoms, and the absolutely brain-dead attitudes towards sexually-transmitted diseases, results in thousands of unnecessary deaths every year – solely from the pursuit of piety, perhaps the most self-centered activity we can get up to as a species. Not only does this ignore every last vestige of evidence, research, and logical thought, it relies on a self-proclaimed authority produced entirely from an arbitrary interpretation of scripture. Condoms (and STDs, and abortions, and myriad other concepts) were completely unknown when scripture was written and there are no references, even obliquely, to their existence – religious pronouncements on such topics come solely from creative interpretation. While a fool might declare their utter confidence in a subjective line of supposition, it takes a special form of hubris to declare such authority from it that one is promoting lethal consequences – especially when also claiming that all life is sacred from the other corner of the same frothing mouth. What’s at work here is strictly emotional, a fixation on some idea that produces strong feelings (such as distaste over pre-marital sex,) that motivates a specious line of rationales in support, rather than any consideration at all that the original idea might be ill-conceived.

There’s a curious progression that can often be found buried within any individual’s activism, or just their strong attitudes – something I touched on in an earlier post. A kernel of trustworthy information forms an initial reaction – say, several corporations have been found dumping hazardous chemicals into public access water – but then the snowball heads downhill. Any and all similar occurrences reinforce the idea that this is widespread or common, without the comparison to how many corporations do not engage in dumping, or the realization that a connection between “corporation” and “toxic waste” is a complete failure of logic, as much so as a connection between “human” and “criminal.” On occasion, supporting “facts” may be selected only on the basis of how much they fit the concept, with no examination of how strong they are or if they even exist. Tied in with this might be frustration that others do not find the topic as important; alternately, that the individual can save many others through their efforts – a hero, if you will. Compounding it might even be an inherent distrust over government bodies, meaning any and all contra-indicators could possibly be deliberate misinformation to allay the public’s reasonable concerns. No single part is particularly farfetched – there have been numerous cases of corporate-level social disregard, and even campaign contributors that received special dispensation from favored politicians.

What’s missed is that the goal is not to concoct the plot of a novel, but to establish real facts beyond a reasonable doubt – not plausibility, but a high degree of probability. And to determine this, anyone must be capable of viewing the details objectively, and with the realization that their emotional commitment can affect their judgment. The problem is, their emotional commitment is the very part that provokes them away from the rational consideration of all the factors – it is more satisfying to prove oneself right (and, quite possibly, heroic) than to find many of the factors to be unlikely or just plain wrong. This immediate emotional indulgence, and often the justifications of an attitude by dismissing the negative evidence, can easily produce actions that actively, irrevocably harm others far more than the imagined fears of the topic of activism ever could. It is not enough to start a journey in the right direction: it must maintain that direction throughout.

Mark Lynas illustrates this at length, in his quest of contrition over his GMO activism. I have a great deal of respect for his ability and desire to correct his mistake, and I sympathize with the guilt he undoubtedly feels. But there’s another lesson in there as well: finding the flaws in his attitude sooner might have prevented a lot of emotional turmoil, and might even have lessened the impact that anti-GMO activism had over the past decade. It’s much easier to prevent a wrong than correct it. To do this, we need to be ready and willing to find where we go wrong – ignoring errors does not make them cease to exist.

Some of our thinking shortcuts can contribute to these errors significantly. For instance, few major decisions present distinctive ‘sides’ or boundaries – they’re far more likely to be shades of grey that require a lot of consideration, but we prefer things to be polarized and often try to make them more so. We also allow ourselves to be influenced by a majority, or believe that someone we like is more trustworthy; celebrities are used as spokespeople because it makes so much sense that a tennis player knows a lot about cameras, right? Large groups of people (that have self-selected by finding only those who agree) cannot be wrong? We can even fall for the idea that if someone came to the same conclusion that we have, their reasoning must be correct. There is no rule that can be applied here, but if we have strong feelings about something, this is a great warning sign that we might be about to mislead ourselves.

There is a semi-common attitude that critical-thinking is almost antisocial, basically displaying distrust in everything (and everyone.) Yet, the alternative can and does result in feeling perfectly accepted in social circles while producing horrific consequences for many others. There’s nothing wrong with protecting animals, with promoting healthy eating, even with discouraging casual promiscuity. But the results are what matters, not the personal feelings of importance.

Checking in

It’s been a little longer between posts than intended, but this only means that truly major, insightful, earth-shaking stuff is coming soon (yeah, yeah, I know; save the sarcasm.) I’ve had a couple of projects going, and have been commenting in other locations, such as Sean Carroll’s Preposterous Universe blog, or maybe it’s S=k. log W, or simply Sean Carroll – I honestly don’t know what he calls it. Anyway, I’ve been having fun with those who have been trying to defend philosophy, and if one thing’s been demonstrated quite clearly, it’s that believing in the power of philosophy doesn’t contribute a damn thing to maturity. I have been nice (well, to a degree anyway) and not resorted to various doth protest too much arguments, which really don’t address the points anyway. And as hard as it may be to believe, I’ve actually been very kind to the evangelist in the comments.

At the same time, Jerry Coyne was trying to help me get through whatever enigma is preventing me from commenting over at Why Evolution Is True, and in thanks I sent him a pic, which he decided to feature. This appears to have opened up his inbox to various other photographic contributions – or perhaps he always gets stuff like that, and because he’s still recovering from his illness he’s simply putting up more effortless content.

Since I try to space out the photographic and critical-thinking and total nonsense posts, I’ve avoided posting more pics, even though I’ve done more shooting in the past few weeks than I did throughout the winter. So while I’m going to throw up another image now, I’m at least going to avoid the arthropods in favor of something cute. Not fluffy, but cute. Hey, at least I’m not featuring photos of the cats all the time…

RhinoLizard
This eastern fence lizard (Sceloporus undulatus, more or less – herpetologists are still pinning down subspecies, and if they don’t know I’m sure as hell not going to be too specific) was found on a tree while I was trying to collect tardigrade specimens – she was counting on both camouflage and a lack of motion to escape my attention, but she might have fared better had she put her head down and not been sticking out into midair. I automatically assumed the “horn” was just a loose scale, since fence lizards do not have such body features, but it doesn’t really look like a minor injury on close examination – perhaps I just had a new mutation in my hands, and let it go merrily on its way (fence lizards being one of the best species to communicate “merrily,” of course.) If you look close, you’ll notice lots of dewdrops all over the head, proof that my model was foraging recently I think, and I like both the visible eardrum and the delicate color of the eyelids at this range.

Tardigrades are far too cool to ignore, but since they run less than a millimeter in length, getting useful images without a photo-microscope could be more of a challenge than I can meet (there, now I’ve covered my ass over any failures.) Still, it’s one of the projects I have going, and I’d be pleased with at least some images in my stock. Watch this space to see if anything actually pans out, and as a bonus, I’ll soon put up my despairing fly pic, which certainly should become an internet meme if you ask me…

Not him again

CoyingMantis
The past few days have been overcast and either rainy or misty, so photo opportunities were a little limited, but the azaleas are in full bloom so they’re providing much better settings for the mantis images now. I remain unsure how old the mantises were when I found them – I’m guessing at least a few days, since their eyes had changed from the dark ones I’ve seen on newly-hatched specimens to having some camouflaging color. I’m also unsure if they need to molt to accomplish that, like most other color changes, but it’s clear that they’ve molted since then, because their coloration is more green and they’re noticeably bigger now, though still tiny. They’re also slightly more complacent, though still not thrilled about my presence, but this means I can do a little more towards creative compositions and something a bit expressive. I’m trying to take advantage of this now, since the blooms will soon turn into crumpled brown petals everywhere and achieving a nice setting will be that much harder.

AntennaeDrops
I’ve been trying out a new lighting system, and so far have been pleased with it. I’ve had an old Sunpak FP38 flat panel flash for a while now, but it saw little use because it was hard to get the right angle. Wide, diffuse, or ‘softboxed’ lighting should largely be over the subject, providing light from a natural angle and giving more shaping and dimension than a straight-on flash provides. The mounting system for the flash is the typical setup though, a standard shoe-mount, which places it high above the centerline of the camera, or high above wherever the flash bracket can hold it. It’s not huge, but big enough to produce a lot of leverage when tilted, hard on both whatever tilting mechanism can be used, and the hand holding the rig (which includes camera, macro lens, and bracket.) I altered this by adding an angled reflector/extension to the front, made from matboard and diffusing cloth, and it’s been working pretty well. I’ll try to feature it in detail later on.

StalkyOn the vines along the fence, I spotted a jumping spider, probably a Hentzia mitrata, ducking under a leaf. That’s simply not acceptable to arthropod photographers, so I snaked a finger underneath and flushed it out. Normally such a display of shyness means good pics could be taxing, since the looming camera is enough to chase the subject back into hiding, but this little guy took it as a challenge. For reasons unknown, he (yes, it’s a male) started stalking me in return, constantly working closer by jumping and scrambling across the leaves; he even stopped twice and attempted to throw a webline into the wind to cross a particularly daunting chasm (when you’re about 4mm in length, this is relative.) The distance I had to maintain for sharp focus meant he never drew close enough to actually leap onto the camera, and I eventually left him extended out on the end of a tendril vine, perhaps frustrated. Who knows what emotions, or their analogs, arachnids feel? And yes, that’s a mist drop atop the cephalothorax.

The bad thing about the flat panel flash is how quickly it burns through batteries – I have yet to convert it to an external powerpack. So when the batteries died during some abstract shots, I switched to a wide-open aperture and used natural light for the following image. It had to be lightened considerably in post-processing (that’s one of those terms left over from film,) which contributed to the grainy appearance, but I think that adds a little more atmosphere to it.
