Here are doctors who've implicitly took an oath to be superstitious and peddle the post hoc ergo propter hoc fallacy.
Needless to say the site is unabashedly blatantly biased. It publishes only those cases where there was prayer somewhere in the patient history after which the patient got better. So what may we ask about those who had the same condition and did have prayer (whatever kind and to whichever deity) but did not get well or even got worse? And what about those who had the same condition who didn't pray but whose condition improved? Moreover, what about the various medical treatments and procedures which the patients were undergoing at the time invisible genies somewhere in the universe or outside the universe were being dialed up? Would the patients have recovered without them? If prayer is a or the panacea and is effective against such a wide spectrum of diseases and medical conditions, why don't these God-intoxicated doctors just turn their cases over to Doc Jesus and have him snap his fingers and make them well? Just replace all doctors in their hospital or clinic with faith healers. If prayer is indeed efficacious then decommision the pharmaceutical industry and have MDs change careers. You don't even need diagnostics of any kind. Scrap all the equipment for X-ray, CAT scans, MRIs, PET scans, blood exams, etc. Just tell people to pray or head on over to the nearest healing priest/pastor/shaman the minute they feel something wrong. It's that simple if prayer really works. It doesn't work that way? Why? How do you know? What makes you think this (peri)omnipotent, (peri)omniscient deity of yours needs your help?
In Neil DeGrasse Tyson's Amazing Meeting 6 talk he declared that doctors are far from being smart. I thought that was a rather unfair blanket statement. Well, I apologize to Tyson. I'm beginning to think he may very well be right after all. Of course, there are doctors who can actually think critically (the skeptics community has a number of them--Steven Novella, Stephen Barret, Harriet Hall, David Gorski) but there really are lots of MDs who don't have their heads screwed on right at all and buy into cockamamie alternative medicine crap out there, including one of the most ridiculous--homeopathy.

Homeopathy is a disease of the mind
Earlier this week I said I found it alarming that a Heel affiliate was promoting what is probably a quack treatment for dengue. I did some googling and apparently there indeed are homeopathic remedies intended to address dengue. For instance Dr. Ana Teresa Doria Dreux, former president of the Instituto Hahnemanniano do Brasil (presumably named in honor of homeopathy's inventor Samuel Hahnemann) and currently its VP, prescribes nostrums for the prevention and treatment of dengue. Her concoction consists of 5CH and 12CH dilutions (equivalent to 10X and 24X). That's 1 part per ten billion and 1 part per trillion trillion of active ingredients respectively. The latter is simply too dilute to have any possible effect (therapeutic or adverse). She tells us that these remedies are her own creations. However, we are not told what clinical trials have been performed to test their efficacy. All she says is:
This of course is insufficient evidence for efficacy. When I read the above the image that pops in my head is that of Dreux tightly crossing her fingers behind her back praying her luck holds.
Despite belief in the efficacy of her anti-dengue nostrum, she cautions:
Dreux and her water institute aside, what is truly disturbing is what the doctor reveals in passing--that Brazil's health department has a homeopathy division. When government legitimizes quackery and itself peddles snakeoil then it has betrayed the people. One can only hope that there are Brazilians who are making noise and who are trying to inject sanity into its department of health.
So far, with those patients who have used this formula as prevention, there have not been any cases of infection, at least not reported to me.
I distribute this formula every year to all the personnel at IHB during the periods of epidemics and since I began doing so, not one of the approximately 22 employees has contracted the disease, not even those who live in areas where it is endemic.
This of course is insufficient evidence for efficacy. When I read the above the image that pops in my head is that of Dreux tightly crossing her fingers behind her back praying her luck holds.
Despite belief in the efficacy of her anti-dengue nostrum, she cautions:
Of course homeopathy does not DO AWAY WITH or INTERFERE with the obligatory medical care in these cases, nor should we neglect to eradicate the vector (the Aedes aegypti mosquito) by eliminating its breeding sites.Well, if "obligatory medical care" and eradication of the disease vector weren't and aren't done away with, couldn't these be the cause of the lack of incidence? Setting aside ethical issues for the moment, if Dreux actually performed a double-blind trial and subjected half of a community to her brew and half to pure sugar pills--withholding any other form of treatment including "obligatory medical care"--perhaps she could have a better idea of whether her "medicine" actually works or not. As it is, Dr. Dreux is infected with dilution delusion. And not even an hourly dose of 100,000X (ultra powerful stuff indeed!) whatnot will cure her.
Dreux and her water institute aside, what is truly disturbing is what the doctor reveals in passing--that Brazil's health department has a homeopathy division. When government legitimizes quackery and itself peddles snakeoil then it has betrayed the people. One can only hope that there are Brazilians who are making noise and who are trying to inject sanity into its department of health.

Close encounters with homeo and acupunc
Accompanied a friend to a trade exhibit last Saturday and encountered two companies promoting and selling woo.
1. Homeopathy and Homotoxicology by Biological Homeopathic Medical Corp (BHMC) / Ibarra Bio Med Int'l Trading Corp.
Let me begin with what may be a tragedy that's in the offing. After I started inquiring about their products alarms went off in my head when the representative at the booth boasted about their company having made a presentation before health officials for a preparation that addresses dengue. What these "medicines" actually are remains to be seen. I gather from the rep that they're alternative meds, perhaps homeopathic. In the recent past there have been homeopaths who prescribed homeopathic remedies for malaria. Such nostrums are completely ineffective against that disease. I'm betting that the treatment BHMC is purveying is just as bogus. These people are toying with lives. Dengue is a very serious condition. Homeopathy should be banned from peddling anything to treat/prevent such life threatening conditions. Hopefully the health department will not get duped. Lives--specially those of young children--are at stake.
Onto the reading materials I was provided. One of BHMC's flier lists the principles "proven and developed by Dr. Hans Heinrich Reckeweg":
The first two principles were in fact laid down by the inventor of homeopathy, Samuel Hahnemann. And no they haven't been proven. The second principle doesn't even need testing. Given what we know about how chemicals work, it's implausible from the git go. It's the very opposite of what we know is true even intuitively--the more of a substance you administer the more pronounced its effect. The less of it you give/receive the less its effects--and that goes for what we commonly call poisons as well. Even cyanide poses no threat if you ingest but a microgram.
BHMC is affiliated with Heel, a company that has distributors in the US, Germany, Canada, Australia, among others. Dr. Stephen Barrett of Quackwatch tells us that Reckeweg founded BHI (later renamed Heel) back in the early 20th century. In the last few decades the company managed to earn the ire of the FDA which regarded it as the "most flagrant law violators among homeopathic marketers." Barrett issues this warning:
The BHMC pamphlet lists its services:
All of the above are unproved therapies. And the safety of some of them is questionable..
The other flier I was handed introduces their Detox Kit. It describes the contents of the kit as follows:
I googled and found the composition of the Heel Detox Kit. The webpage lists all the active ingredients and even the amount of each per 100 milliliter bottle. With this data I created a spreadsheet which shows the actual amount each of the active ingredients taking into account their respective dilutions.
For the Nux vomica-Homaccord drops they list 22 substances:
You can't help but notice that in fact there are only 4 ingredients. They've merely used various dilutions of these four. If you look at the last column (% of total active ingredients) of the spreadsheet you'll see that the contributions of dilutions other than D3 are completely negligible.
You're probably wondering what this "Dx" rating is all about. In homeopathic terminology D stands for decimal. It's a scale to denote the degree of dilution. A D1 means there's one part of active to 10 parts inert ingredient. For a D2 it's one in a hundred. So it's a logarithmic scale similar to the Richter scale for earthquake intensity. Being logarithmic a D4 is ten times more dilute than a D3 preparation [10(4-3)], a D6 is a thousand times more dilute than a D3 [10(6-3)], and a D30 is a thousand trillion trillion times more dilute than a D3 [10(30-3)].
In the Nux vomica oral drops some of the substances are watered down to D1000. How dilute is a D1000? If you had one drop of active ingredient and were to dilute it in one go you'd have to mix that single drop with 101000 (remember, that's "1" followed by a thousand zeros) drops of water or alcohol. How much is 101000 drops? That's equivalent to 6.5 × 10992 cubic meters [see Note 1]. And just how large is that? Well, it's more than the size of our universe. In fact a lot bigger. If a bucket were the size of the universe you'd need 7.7 trillion buckets to end up with 6.5 × 10992 m3 [see Note 2]. After mixing (if you can even imagine achieving that) you can scoop a volume as large as the Earth or the Sun or the Milky Way and the chances of finding a single molecule of the active ingredient would still be exceedingly infinitesimal.
Since it is impossible to make extremely dilute preparations in a single step, homeopaths perform a series of successive dilutions. For example to obtain a D1000 they may mix a drop of the active ingredient in 105 drops of water--equivalent to 6.5 liters. This is now a D5 dilution. A drop from this is then added to another 6.5 liters of water to create a D10. And so on until it's been performed 200 times. Here's another way of looking at that. Let's say the entire Earth all the way to its inner core is made of water. You add a drop of the active ingredient and mix thoroughly. Take a drop of that and add it to another Earth-sized planet made of pure water. Remember to mix it real well. To end up with a D1000 you'd need to do this 45 times [see Note 3].
As we've seen homeopaths claim that the more diluted a preparation the more potent it is. Thus a D1000 is far more powerful than a D10 even if there's negligible chance of finding even a single molecule of the substance that's suppose to treat the condition. This is dilution delusion.
According to Heel the Detox regimen consists of "30 drops of each preparation in 0.7-1.5 liters of spring water to be drank during the course of the day." In the spreadsheet I've computed how much of the active ingredients one actually gets daily.
These are very minuscule amounts indeed. Which means to say they probably have neither therapeutic nor adverse effects.
Just to get a perspective on how small those amounts are, let's compute for how many days it would take to ingest a drop or milligram of the active ingredients. To compute, just get the inverse of the above values. We obtain:
Finally, is there anything to the notion of detoxification? None. It's bunk. It's crap. It's woo.
2. Shaolin Electronic Acupuncture Apparatus
The apparatus consists of an oval plastic device with a major diameter of around two and half inches, with "wings" on either side made of some pliable material under which are attached a black, sticky material they call the plaster or patch. Click the above link for photos. Here are a couple of infomercial videos I found on Youtube: the original is in Chinese but here's one in English.
The apparatus is manufactured by Zhengzhou HuiHao Technology Co.,Ltd in Zhengzhou, China. The device is powered by a coin battery and is said to incorporate a microprocessor. They probably mean microcontroller but then the terms are sometimes used interchangeably in reference to embedded systems.
The flier I got explains how it works:
The following are the diseases and conditions the device can purportedly "prevent and cure": Arthritis, diabetes, rheumatism, backache, sciatica, impotence, joint pain, Bell's palsy, kidney problems, stiff neck, vertigo, insomnia, constipation, gastroptosis, nausea, gastroenteritis, tennis elbow, hangover, hypertension, stroke, headache, gonarthritis, bone diseases, cervical spondylosis, scapulohumeral periarthritis, hip pain, inflammation of the lumbar discs, hemiplegia, carpal tunnel syndrome. It can also help rid (excess) fat, expel toxins, relieve pain, provide energy, free the "channels and collaterals", and promote blood circulation. I'm surprised they left out the big C--cancer.
According to the video the sticky patch contains a secret Shaolin concoction made from 13 herbs. These seep into the skin five times deeper than without the electronic apparatus. As to how deep the herbs penetrate without the device they don't say.
The exhibit representative urged me to try the apparatus for just ten minutes. Although reluctant at first I did give in and allowed myself to be a guinea pig just to see what the gizmo would do. Boy, was I in for a surprise. The lady strapped the device onto my forearm and pressed a button. Within seconds it started delivering electric shocks. Not very pleasant at all! My hand twitched violently with every shock as the device caused my arm muscles to contract. The pulse frequency was approximately one per second. But every half minute the frequency would change.
Given its shocking output I believe this gadget employs an inductor--a coil of (enameled) wire (probably with an iron core)--to produce a very short but high voltage output. Whenever current passes through a conductor a magnetic field is produced. When wire is formed into a coil the magnetic field around the entire length of that wire becomes concentrated--the inductance increases. When current stops flowing the magnetic field around the coil collapses. But that collapsing field now induces a voltage in the coil--a voltage that is many times that which was present when current was flowing. But while voltage is high there is very little current that flows--and it's the amount of current that can kill, not necessarily the voltage. Thus while static buildup in our body can easily reach a thousand volts, we don't feel more than a sting when we discharge the accumulated charge.
If the acupuncture gadget does employ an inductor then it works on the same principle as the ignition coil in a gasoline engine. But in this case you and I are the spark plug. Try the following (if you dare). With the engine off, pull the cable off one of the spark plugs. Hold the end of that cable--called the boot. Best if you hold a metal rod and stick it inside the boot so you can make contact with the metal shroud inside. Have that hand also touch the body of the car (ground). As a safety precaution put your other hand behind your back and avoid having any other part of your body in contact with the vehicle. Now let someone crank the engine. Unless your body is made of plastic, rubber, glass or some excellent insulator, you'll get a pulsing jolt. I've had my share of surprises when I was still tinkering with engines decades ago. So in case you want to experience electronic acupuncture, your automobile will gladly assist you.
A car's ignition coil delivers around 20,000 volts to the spark plug causing an arc to jump across the electrodes. It's this arc which ignites the gas-air mixture in the cylinder. Now think about that. What do you think will happen if you bring this acupuncture gizmo to the gas station and turn it on as you're filling up? Well most likely nothing (unless perhaps you put it right next to where you pump gas into car's gas tank). But put it inside a jar with a rich gasoline-air mix, set the gap between the electrodes to less than 5 millimeters, program the apparatus to maximum output, and maybe, just maybe, you'll have an early New Year's Eve celebration.
Instead of acupuncture the manufacturer should've called it The Portable Electro Shocker. Does it work? It certainly does! For those who have a masochistic streak in them, that is.
Notes:
1. One drop = 0.065 ml = 6.5 × 10-8 m3
Cubic meter equivalent of 101000 drops:
101000 drops × 6.5 × 10-8 m3/drop = 6.5 × 10992 m3
2. Volume of the universe = 3 × 1080 m3
number of universe-fuls of water (or alcohol) required to dilute one drop of active ingredient to D1000:
[6.5 × 10992 m3] / [3 × 1080 m3] = 7.7 × 1012
3. Volume of the Earth = 1.08 × 1015 m3
Let 10x = volume of the Earth in drops
6.5 × 10-8 m3/drop × 10x drops = 1.08 × 1015 m3
10x = [1.08 × 1015] / [6.5 × 10-8]
10x = 16.6 × 1021
x log10 = log (16.6 × 1021)
x = 22.2
number of Earth-sized successive dilutions to achieve D1000:
1000 / 22.2 = 45 Earths

Lives--specially those of young children--are at stake.
Onto the reading materials I was provided. One of BHMC's flier lists the principles "proven and developed by Dr. Hans Heinrich Reckeweg":
1. Like cures like
2. The more the remedy is diluted, the greater its potency
3. An illness is specific to the individual
The first two principles were in fact laid down by the inventor of homeopathy, Samuel Hahnemann. And no they haven't been proven. The second principle doesn't even need testing. Given what we know about how chemicals work, it's implausible from the git go.

In the last few decades the company managed to earn the ire of the FDA which regarded it as the "most flagrant law violators among homeopathic marketers." Barrett issues this warning:
Heel-BHI has been marketing products with outrageous and illegal claims for more than 25 years. The vast majority are irrationally formulated and have not been scientifically tested. Using them instead of proven therapy is a waste of money and could lead to delay in getting appropriate treatment.
The BHMC pamphlet lists its services:
Electroacupuncture by Dr. Voll
Super MORA Therapy
Bio Oxidative Therapy
Ozone Therapy
Chelation Therapy
Neural Therapy
Bio-Puncture
Colonic Hydrotherapy
Traditional Chinese Acupuncture
Anti-Ageing Therapy
Natural, Nutritional and Biological Preventive Medicine
All of the above are unproved therapies. And the safety of some of them is questionable..
The other flier I was handed introduces their Detox Kit. It describes the contents of the kit as follows:
The Heel Detox Kit® combines three homeopathic complex remedies for a comprehensive effect.
Lymphomyosot® Oral Drops
activates the lymphatic system in order to detoxify the connective tissue and the mesenchyme
Nux vomica-Homaccord® Oral Drops
stimulates the gastro-intestinal excretion pathway as well as the hepatic system (liver)
Berberis-Homaccord® Oral Drops
activates the renal and the biliary systems (kidney, gall bladder)
I googled and found the composition of the Heel Detox Kit. The webpage lists all the active ingredients and even the amount of each per 100 milliliter bottle. With this data I created a spreadsheet which shows the actual amount each of the active ingredients taking into account their respective dilutions.

Nux vomica D1000
Bryonia alba D3
Bryonia alba D6
Bryonia alba D10

Bryonia alba D200
Bryonia alba D1000
Colocynthis D3

Lycopodium clavatum D3
Lycopodium clavatum D10

Lymphomyosot (or Lyphosot): 0.0087 drop (equivalent to 0.00057ml)
Berberis-Homaccord: 0.084 mg.
These are very minuscule amounts indeed. Which means to say they probably have neither therapeutic nor adverse effects.
Just to get a perspective on how small those amounts are, let's compute for how many days it would take to ingest a drop or milligram of the active ingredients. To compute, just get the inverse of the above values. We obtain:

Lymphomyosot (or Lyphosot): 115 days / drop
Berberis-Homaccord: 12 days / mg

The flier I got explains how it works:
A Microprocessor [sic] generates a low frequency magnetic field while [sic]controls a modulated pulse that provokes slight vibrations to simulate therapy by acupuncture. This function stimulates the channels and collateral in our body thru a patch helping to promote blood circulation to relieve pains; eliminates [sic] dampness to invigorate the kidneys; expel toxins to lose fat, etc. It also achieves [sic] and has very good healing effects on inflammations and aches of the neck, shoulders, waist, legs and joints.
The following are the diseases and conditions the device can purportedly "prevent and cure": Arthritis, diabetes, rheumatism, backache, sciatica, impotence, joint pain, Bell's palsy, kidney problems, stiff neck, vertigo, insomnia, constipation, gastroptosis, nausea, gastroenteritis, tennis elbow, hangover, hypertension, stroke, headache, gonarthritis, bone diseases, cervical spondylosis, scapulohumeral periarthritis, hip pain, inflammation of the lumbar discs, hemiplegia, carpal tunnel syndrome.

Justice with Michael Sandel
Just learned of that lecture series on ethics. The first two episodes are already up for viewing. Succeeding ones will be uploaded once a week. While watching the preview/teaser, "Star Trek!" was the first thing that popped in my head. Ethical questions and dilemmas are what draws me to that sci fi series.
Prof. Sandel begins his first lecture with the (classic) trolley (or train) problem. It exposes how we humans basically are utilitarian when faced with no option but to choose between the lesser of two evils. (By the way, Sandel sounds like Command Data of Star Trek: The Next Generation)
In the movie The Wrath of Khan the dying Spock tells Kirk--having sacrificed himself to save the crew: "The needs of the many outweigh the needs of the one." That's utilitarian logic. And we all extol such such self sacrifice.
Seven years ago, after watching a Star Trek Voyager episode (you can watch it on Youtube) I wrote the following analysis of the ethical questions which it raised and tackled.

Seven years ago, after watching a Star Trek Voyager episode (you can watch it on Youtube) I wrote the following analysis of the ethical questions which it raised and tackled.
I. The Storyline
In the episode "Nothing Human" the crew of the starship Voyager comes to the rescue of an intelligent yet heretofore unknown alien species, one resembling a very large scorpion or lobster. Because its ship is badly damaged Captain Kathryn Janeway decides to beam the lone survivor to sick bay, knowing fully well that by bringing this 'stranger' on board her ship she is putting Voyager at risk.
Preliminary diagnosis indicates that the creature is ill or injured. Though at first docile this creature moments later pounces upon the ship's engineer B'Elanna Torres and attaches itself to her, pierces her neck, and starts injecting substances into her body and sending tendrils into her major organs. By so doing the creatures survives by parasitically siphoning her energy and nutrients (reminiscent of Dracula).
Unable to decipher its language consisting of shrills the crew has no way of understanding the motives of this creature. They don't know whether it has attached itself to Torres because it merely wants to survive or whether it has more long term malevolent intents.
Knowing nothing about this creature and its anatomy, Voyager's chief medical officer "The Doctor" (a hologram) decides he needs the assistance of a Cardassian medical expert on exobiology. The engineers toil to create a holographic representation of Dr. Crell Moset, a feat they manage to pull off. After the Doctor explains their predicament Moset proceeds to examine Torres and the alien creature. But because the equipment on board Voyager is inadequate he asks that his laboratory be recreated in order that he may have access to the specialized instruments he requires to further examine this creature.
While Doc and Moset try to learn about the creature and ultimately devise a method to remove it from Torres without killing her, one crew member, Ensign Tabor, by chance comes face to face with Moset. The Bajroan is aghast and is unable to contain his rage. He accuses Moset of having murdered his family by exposing them to all sorts of radiation and chemicals as part of his medical experiments. The Doctor cannot believe his ears. Surely there has been a mistake. The great Dr. Moset singlehandedly came up with a cure for a rare disease and saved thousands from the fatal epidemic. It must be a simple case of mistaken identity.
But alas, searching through the ship's database, the crew piece enough information that corroborates Tabor's allegations: the 'good' doctor indeed had performed horrible experiments on Bajorans directly causing the death of dozens if not hundreds of their people.
Captain Janeway calls for a meeting. Voyager is caught in a dilemma. How can they let Moset continue helping them when the very knowledge he's utilizing was gained from his murderous experiments? Given the fact that his expertise derives from many counts of heinous crimes, is it at all conscionable to use whatever Moset has to offer to save the life of Torres, notwithstanding that this Moset is merely a holographic representation? No, they say, not even if it's only a hologram since the representation relies on the actual Moset files found in Voyager's database. The debate among the officers heats up. Several want the Moset program terminated immediately. Even the Vulcan Tuvok agrees that it is logical for Torres to refuse help from Moset. However, a few believe that saving Torres is more important and that the chances of doing so drops to nill if Moset's expertise becomes unavailable. The captain must make a decision. And she is forthright and does not dally, giving us the impression she had already made up her mind even before she called for the meeting. For now she says Torres is more important to her than ethical issues and instructs the Doctor to continue working with Moset.
In Moset's recreated lab he and the Doctor successfully induce the creature to retract its tendrils and free Torres from its death grip, by applying a neurostatic shock to its nervous system. They move on to sickbay and try the method, for real this time. But while Moset wants to apply a large dose of electrical shock ensuring rapid retraction of the tendrils, Doc intervenes and takes over, and applies a less than lethal dose to the creature.
Meanwhile, the comrades of this alien creature have arrived and are pounding Voyager. Its energy shields are useless against the aliens' weapons. Voyager still does not understand the shrills even as the crew tries desperately to telll the aliens that they mean no harm. It is clear, however, the aliens want their comrade back.
Over in sickbay the Doctor manages to induce the creature to finally let go of Torres. With the separation complete engineers are finally able to lock onto the creature and beam it to its ship. With mission accomplished the alien ships depart without damaging Voyager. They even seem to say "thank you" on their way off.
In the aftermath Captain Janeway tells the Doctor that as the medical expert on board he must decide the fate of Dr. Moset. It will up to him whether to retain Moset or pull the plug on this most controversial hologram. The Doctor arrives at Moset's laboratory. The latter is stowing away his instruments while humming a tune he and the Doctor had sung during their most fruitful collaboration earlier.
The Doctor tells Moset that he has come to inform him of his decision. The Cardassian understands that the Doctor is still bothered by his shady past and so tries to persuade him that what is important are the results. That he was able to cure thousands during the war. Moreover, that the two of them were able to save both Torres and the parasitic alien creature should be considered a victory. The means by which they managed to do that is irrelevant. The eloquent Moset puts up a convincing argument. He even reminds the Doctor that humans had for decades used animals to test virtually everything that humans dare not try on themselves. But the Doctor has already made up his mind. No argument by Moset can possibly make him reconsider. He hails Voyager's voice-activated computer and commands it to delete the Crell Moset program and all files related to it. The laboratory and Dr. Moset, murderer and savior, disappear from the holodeck forever.
II. The Issues
A. Moset's Move
Was it right for Dr. Moset to conduct his medical experiments on Bajroans, to use them as guinea pigs and in the process maim, mutilate, and eventually kill them? No. I doubt any one of us would agree. Those who dare say yes should be ready to stand beside Moset and infect, irradiate, and eventually kill any number of people.
The end does not justify the means, certainly not in this case. But this is exactly the point around which Moset's argument revolves. The Cardassian doctor believes that the thousands who were saved did justify the (cruel) means he employed. Moset is a utilitarian, i.e., he believes that if a hundred thousand lives can be saved by sacrificing a hundred or a thousand then it is a good bargain and one must go for it unhesitatingly. Moset would further argue that with the knowledge gained from experimenting on Bajorans (or humans for that matter) medical science would be so served and advanced that the potential benefits may be even more than what is now apparent.
The utilitarian angle is an attractive argument and many throughout our history have so reasoned and rationalized their actions this way.Surely if I deny myself the several dozen books I would like to purchase right now and instead place that money in an investment that gives a return of a whopping 20% per month I'd be able to enjoy even more books next month. In this rather trivial case the small amount of pain that I suffer today from being deprived of much desired reading material indeed is more than offset by the greater amount of enjoyment I will experience in the near future. Delaying gratification, of course, if one of the signs of a mature person (very young children as we all know fail this test miserably). In this sense utilitarianism may be a good thing.
The English philosopher Jeremy Bentham (1748-1832) was the founder of utilitarianism and made it famous (or infamous) with his formula that we must strive for the greatest happiness of the greatest number. Doubtless our Cardassian doctor would gleefully assent. And to the sure delight of Bentham, Crell Moset is a utilitarian to the very end and in every circumstance. He is a doctor, but with a twist. He wants to save and cure people, yet he is ready to sacrifice a 'few' if that would ultimately enhance the life of more people. For Moset the injunction "Do no harm" is not absolute if in the end more will benefit.
On the other end of the scale is Ivan Karamazov of Fyodor Dostoevsky's novel The Brothers Karamazov. Ivan argues that if the salvation of the entire world were to be founded on the abominable suffering of but one little girl then it is not worth it at all. In fact it is unthinkable, so much so that Ivan would rather return his ticket to God. The price is simply too much to pay. Indeed who amongst us would agree to such a Faustian bargain—one tiny insignificant soul for the salvation of the entire world? Tempting sometimes, until you're handed the stick and asked to torture the child yourself.
B. Voyager's Move
The dilemma on board the Voyager is whether to allow Moset to continue counseling them, thereby directly benefiting from the murderous experiments he conducted, expert opinion which would probably save Torres; or whether to delete the Moset holographic program, thereby denouncing in no uncertain terms the crimes against humanity (or Bajorans) committed by Moset, a move which will almost surely lead to Torres' death.
Let us now tackle the argument by some of the crew members that it is absolutely wrong to reap any benefit from the work and expertise of Moset because they were gained through the most unethical means imaginable. Was it wrong for Captain Janeway to use Moset in saving Torres? Does her decision make her an accomplice to Moset's crimes?
My personal response is this: While it is incontrovertible that Moset's experiments were criminal in nature, that the harm he willfully inflicted upon the Bajorans cannot and should never be countenanced, the fact remains, today, that what happened had happened and that we now have in our possession the medical knowledge, the know-how which can and does allow Star Trek doctors everywhere to help cure and save lives, indispensable knowledge without which many will not be saved. I am of the opinion that we must not throw away that knowledge simply because it was derived unethically. If that knowledge is summarily discarded then the suffering of those who served as Moset's guinea pigs would have been in vain. Not only had they been tortured, but the only good that ever came out of their suffering and untimely death would be put to death as well.
We cannot change the past. History is like a moving hand that writes which, having writ, moves on (Rubaiyat of Omar Khayam). That Moset committed crimes against humanity is undeniable. That he was able to use the knowledge gained from those crimes to save not a few cannot be denied as well. That the same knowledge will benefit others in future (as in the case of Torres) must also be acknowledged. Call it some form of pragmatism but it is not conscionable to me to deny a starving family a loaf of bread just because that particular loaf had been stolen. If that stolen loaf is the only sustenance available that will keep that family from dying tonight in their sleep, I see an imperative for all to immediately offer them that loaf however it may have been acquired. There are priorities. And life is one of them, as Captain Janeway correctly recognized.
On the other hand, if the knowledge we had derived from the suffering of those Bajorans was how to kill more people more efficiently and effectively, then, yes, we most certainly must immediately efface, erase, expunge, and raze all the knowledge Moset had acquired.
III. An Experiment of Our Own
Let us imagine that we have been transported to the time when Crell Moset was just about to conduct these experiments. Further, let us suppose that conducting these experiments is the only way the for the doctor to find a cure for the hundreds of thousands who are dying. Moreover, let us also suppose that we have enough authority and power to stop Moset from continuing with his experiments. Let us also assume that we can see the future well enough to know of the alien creature that will attack Torres which would thus require the services of Moset, and that if we stop him from performing his experiments now the future Torres will surely die. The question for us who can grant Moset the thumbs up or down is: Should we allow Moset to proceed unimpeded? Given our perfect foreknowledge can we deny the hundreds of thousands, and Torres as well, the medical knowledge that will cure and save them? How would you answer or change your answer if one of those who will eventually be saved will be your 4-year old child? How will you answer or change your answer if all of those who will be saved are the people who invaded your country and massacred your people, leaving you widowed?
If we permit Moset to conduct his experiments then we become utilitarians ourselves just like Bentham and Moset. Morevoer, we would become accomplices to murder and all the crimes Moset will commit in the name of medical science.
Although the experiments will surely yield the answers we need to cure a whole generation there is no rationale that can permit us to decide the fate of a few in order to save the many. The end does not justify the means, however much more good there will be (as if we can, with ease, quantify goodness, happiness and utility) in the end than what we started with.
Therefore, while knowledge that already exists should not be discarded despite the means by which it was gained, consenting to create new knowledge through such means is not an option.

Rated X
Among the most important people in my life are my nephews--my sister's children. Over the past couple of years I've become some sort of a de facto tutor to her 5- and 4-year old sons. I'm a handyman and so I bring my toolbox(es) almost every time I visit my sis--not least because there's always something she needs fixed. Soon after I arrive the kids would come flocking to the toolbox and start the mayhem--littering the floor with pliers, screwdrivers, electrical tape, ... and trying to snatch my digital multimeter. Of course I have to be there to supervise and keep in check their insatiable curiosity lest they hurt themselves. I know I'm asking for disaster and their mother frowns upon the activity. Though real tools are not at all kid-friendly I'm happy to say that they've learned the names of all the basic tools and can even manage to fasten and unfasten real screws (on second thought that may not be all a good idea--I shudder at the thought of one of them grabbing a screwdriver behind their parents' back and jabbing themselves accidentally while taking their toys apart). But what I'm most proud of is the fact that I've been one of their English teachers so to speak, correcting their mistakes, expanding their vocabulary, reading them stories. We live in a trilingual community and I've set it as my goal to make English their first language. An uphill battle most certainly, but I wouldn't let anyone else have this dirty job.
Well, having said how much I am part of these children's lives and how I find it so fulfilling, my almost irrational reaction to what just happened last night to the eldest will be in context. I found out from my sister this morning that her husband was watching a TV program last night. Apparently, John was watching too. At one point he turned to his mom and asked why the man was bleeding. His mom replied that the blood isn't real and the man was just a statue--although a life-sized one. A couple of seconds later John burst into tears. His mom rushed over and hugged him, trying to console the frightened child. She told him not to be afraid, that it wasn't really blood, just red paint and that it's dripping because the artist hadn't finished his work yet. The scene so traumatized John that an hour after he was still in a state of unease, still asking about the blood. In fact it was so bad that even after bedtime he kept waking up. He was able to sleep soundly only past midnight.
So what exactly did my nephew see that rattled him the whole night? John saw a naked man impaled on a cross, complete with blood oozing out of his hands (and perhaps feet). The TV program was a mini documentary on the life and sainthood of that Catholic priest Padre Pio, a purported stigmatist.
We adults who've grown jaded and inured to seeing crosses can't imagine how frightening and nightmarish it must be for a young child to see it for the very first time particularly when they've already sustained previous injuries and understand pain. In John's case he's already experienced various cuts and even a fractured arm and knows blood and pain very very well.
So here's a human being, practically naked, hanging from pieces of timber--nailed! to it--and bleeding to death. How awfully disturbing that must be! I imagine in that child's mind, in some way, he was able to apprehend how he could or would share the same fate, that he would be subjected to the same pain and suffer the same tortuous death.
My sister knows very well that I'm an atheist. I told her that what happened to John has made me angrier than ever. Not at the parents of course. At religion. As others have already pointed out using other hypothetical examples, what if some religion had for its central symbol a depiction of how their holy teacher or god-man was racked, eviscerated and quartered, because that's how he gave his life to save humanity. How would Christians react to that? Would their pastors and priests see no psychological harm in exposing youngsters--particularly those whose parents belong to that disemboweled man's religion--to such pictures and "artistic" works? The cross with a lifelike depiction of a bloodied dying man is a gruesome image. To subject children to such violence is downright insane! It's so graphic that's it's porn. It should have an X rating. And yet weekly, we have children dragged to churches and treated to a giant cross behind the altar complete with naked, tortured Jesus on it. I think this qualifies as child abuse.
My sister now knows more than ever that she has to be careful what her kids watch on television. She's been pretty successful in keeping the tots from seeing violent programs (needless to say, toy guns and swords are absolutely banned in her home). I believe now she's also aware that she has to be on guard against religious insanities as well.
It's been half a day since the news but I'm still seething. My sister warned me not to ask John about the nightmarish scene he saw. He's suffered enough. We certainly don't want to resurrect thefearful feelings dread. I'm still so angry that John went through what he did.

The miracle we need is the extinction of ignorance
When religionists jump up in joy upon hearing a supposed medical miracle what I hear their consciousness/unconscious telling me is:
Folks, beware of this mind virus. Prevent infection and save your mind. Inoculate yourself at the nearest critical thinking clinic.
I'm really so hungry for signs. So without even having the foggiest idea of the thousands of medical events occurring daily worldwide, I find this one--in my medical and scientific ignorance--to be extraordinary and see it as a miracle--a supernaturally caused event. Forget the fact that this medical event is (merely) a statistical outlier (occurring at the tail end of the bell curve--the positive end of course, not the negative). And perish the thought that I'm calling this a miracle not because there is evidence for the supernatural but because I am--in my breathtaking ignorance again of course--at a loss for the real explanation. No one else seems to know or wants to provide a natural explanation, therefore, in unabashed hubris I declare that I do know and that it was caused by G, and mind you not just any G, but my G. It is a miracle because I want to believe it is and I say it is. Now fuck off and leave me to my delusions.
Folks, beware of this mind virus. Prevent infection and save your mind. Inoculate yourself at the nearest critical thinking clinic.

Talking to the wind
Sit down, close your eyes, relax, and be mindful of your breathing. Now repeat after me: "Kalenbo utam, mitao grekkang tho. Kalenbo utam, mitao grekkang tho! Kalenbo utam, mitao grekkang tho!!" Peace unto thee. Your stage 4 cancer is cured.
Can anyone explain and prove to me how mere concentration and utterance of words (in whatever language, terrestrial or otherwise, fictive or otherwise) can possibly affect malignant cells?
If chants and thoughts are indeed effective in curing ailments and disease why then is a faith healing "clinic" in New Zealand offering patients free prayer therapy but advises its patients "to not stop regular medical treatment"? If mumbo jumbo actually can zap cancer et al., what need is there for medication? And if the patient does get well, shouldn't the drugs receive the applause?
I'm sorry but I cannot have any respect for the cockamamie belief in supernatural friends (and in a supernatural family where the father is the son and vice versa) and belief that talking to them will get them to come thru as benefactors--in other words, genies. On the contrary, I only have unbridled derision for such beliefs. In the context of 21st century life, they're pure malarkey.
The anecdotes of cure these faith healers provide are no different from those of other forms of quackery. I could very well market pure water (without saying it's just water of course) aggressively and enthusiastically as a cancer cure, and after I've duped a few dozen into buying, I'd be able to glean more than a couple of positive testimonials which I can then use to further promote my absolutely bogus product.
