  1. Re:Homeopathy test results on 13 Things That Do Not Make Sense · · Score: 1
    most believers will be undeterred by any amount of evidence. The real question to test a practitionner of alternative medecine is to ask: what would it take you to admit that it doesn't work? For many, nothing will.

    Yes, obviously. Alternative medicine achieves its successes by maximizing the placebo effect. Some types of alternative medicine add a physiological effect on top of the placebo effect, but many don't bother. Therefore, alternative medicine can only work if practicioner and patient believe in it.

    The traditional approach of double blind study is inappropriate if you try to evaluate a treatment whose whole purpose is maximizing the placebo effect. Traditional medicine considers the placebo effect an irritant and tries to minimize it.

    There's also the following paradox: suppose treatment X works pretty well. You do a study and prove that the effect is exclusively due to the placebo effect. Once people learn about your study, they won't believe in the efficacy of X anymore ("it's all just make-believe"), and consequently X won't work as well anymore.

    The real velocity at which the first bit of information travels is called the signal velocity, which is how fast a waveform shaped like a heaviside step function travels. It has been theoretically proven about fifty years ago by Sommerfield and Brillouin that this signal velocity is always c regardless of the dispersion of the medium.

    Are you really saying that the signal velocity is always equal to c, or rather that it can never exceed c? Wouldn't a medium that slows down all frequencies equally also slow down the heaviside signal to the same degree?

    So Public libraries have a backdoor way to extend copyrights. Electronically duplicate the original image, on which the copyright has expired, then copyright the electronic duplicate.

    No, you can't get a copyright for a mere scan, because making a scan is not a creative act. I believe they hope to use contract law somehow: by downloading a copy from their site, you implicitly agree to a contract saying that in return for the image you promise not to distribute it any further and not to use it for commercial purposes.

    Does information just arise out of nowhere?

    Well, several patentable inventions have been constructed using genetic algorithms, by random mutation, selection and recombination of inferior structures. The eventual inventions were much better than anything the programmers could have come up with on their own, so it's clear that new information can and did arise under those conditions.

    For an example from biology, just take bacteria that mutate to become resistant to a new antibiotic. The experiment is done in every microbiology class. Clearly, the information about how to resist the antibiotic arises by random mutation and selection.

    life could be common in the universe, but why can it not be attributed to a mind that has made it happen in many places

    That mind would surely be part of some life form, just like our own minds? So every scientist would immediately ask: how did that life form come about? Did it arise by random mutation and selection? If not, what other process was at work? You can't just arbitrarily stop in the middle of your chain of explanations, unless you are talking religion and not science.

    Let's assume A moves relative to B. Suppose B chooses a point p that's at rest with respect to his reference frame. He sets off an explosion at point p and 1 second later (according to his clock), another explosion at point p. Then A will measure that the two explosions happened more than 1 second apart. The exact factor is given by the Lorentz formula. (He will also think that the two explosions happened at two different locations.) Now if A chooses a point q that's at rest with respect to his reference frame and sets off an explosion at point q and 1 second later (according to his clock), another explosion at q, then B will measure that the two explosions happened more than 1 second apart (and at different locations). The situation is thus completely symmetrical and there is no problem whatsoever. If we set off an explosion at x, then A stays at x and B travels far away and eventually returns, at which point we set off another explosion at x, then both will agree that the two explosions happened at the same spot, and B will measure a shorter time between the two explosions than A. That's the twin paradox. The situation is no longer symmetrical: B was accelerated and A was not.

    Convenient, but it avoids the question of how one decides when there is disagreement.

    True, but even more so for all the religious-based ethics. God never explicitly talked about the ethics of using anencephalic babies for medical experiments, so what do you do if one priest argues in favor and another against? Follow your personal preference?

    But now that you've judged God and found Him wanting, now what?

    If I believed He existed, because of my dislike for His personal moral choices I would simply ignore Him, in the way fishes ignore their Aquarium Keeper. Of course, there's always the option of picking another God that better fits your personal preferences; after all there are enough religions to choose from, with none of them being significantly more convincing than the others.

    Why is that a cop-out

    If you define "good" as "whatever God says or does", then the statement "God's actions are good" becomes a mere tautology without any nutritional value. In the same way, I could redefine the word "good" so that all actions of my laptop become good.

    It turns out, neither of us is completely free to define the word "good" in any way we want, since the word already has a widely accepted meaning, and any proposed definition would have to capture (most of) that meaning. I claim that the two definitions "good is whatever God says or does" and "good is whatever my laptop does" are equally wanting, since they both disagree with the commonly accepted meaning of the word "good", i.e.: don't harm others, be nice and honest, help others, etc.

    The choice of rationale is by personal preference.

    True, but fortunately the different rationales lead, in most real-world cases, to the same answers to basic moral questions. The notions of right and wrong, it turns out, are pretty robust against changes in the used rationale.

    The bigger problem is: who are you to judge God?

    Why should God's personal choices be beyond judgement? Because he is assumed to be very powerful? Should I be afraid? Or because He made everything? Should I be in awe? As you yourself pointed out, those features are orthogonal to moral value.

    And on what basis will you do so?

    I will take utiliarianism as my basis, and will declare that, on this basis, many of God's actions are evidently bad. You are of course free to use another basis. I challenge you to come up with a reasonable definition of "good" which will judge God's actions as good. Except of course the cop-out "it's good because God does it".

    No, ethicists usually give much more elaborate reasons, such as "because it leads to the largest amount of happiness for the largest number of people" or "because it will ultimately maximize your personal happiness" or "because every group of free rational and equal agents would agree to these principles" etc.pp.

    while the Deist says, "This is good because God says it is." (with the attendant problems of "which God" and "how do you know you heard correctly?")

    Not to mention the much bigger problem: why should one assume that God's personal notion of "good" agrees with a reasonable human notion of "good"? After all, a God whom it pleases to snuff out 150,000 innocent people for fun may very well invite Hitler into heaven. God's ways are unknowable.
