    Oops. Made another mistake. Based on:

    Most objections to Judeo-Christian morality are rooted in two causes: 1. Personal vice. 2. Inexperience. The first is almost never philosophical. The second is almost invariably philosophical, but dwells on matters in which the philosopher has no actual experience.

    So... because you've changed your mind in the past, there has to be a supernatural force affecting the physics that govern your neurons? Wow.

    I've previously said that free will seems like a nearly insurmountable philosophical problem. Supernatural effects don't seem to fix this problem any more than classical nondeterminism through exponential dependence on initial conditions or quantum nondeterminism. These "quick-fixes" either turn a deterministic, predictable system into a deterministic but unpredictable system, or a genuinely nondeterministic system that obeys statistical laws. Supernatural effects seem similar except they wouldn't necessarily have to obey statistical laws.

    But just like quantum nondeterminism doesn't adequately explain free-will, supernatural effects don't seem to explain the subjective impression we have of free-will. How would supernatural violations of (say) conservation of energy or momentum result in my subjective impression that I make my own decisions?

    Appealing to magic to find a quick answer to a hard problem is tempting. Especially when that answer also implies that death is just a transition to see our departed loved ones, that evil people will be punished in this life or the next, and that we're not insignificant mayflies in an oppressively vast universe.

    In contrast, saying "I don't know" isn't nearly as satisfying an answer. But sometimes that's all we can say.

Right now, pro-choicers are up in Stalin territory, who reputedly killed about 55 million. But I didn't write this post (or its parent) to bash pro-choice people. But trollish rhetoric aside, there are some points I'd like to clarify: But since you had to mention the Nazis... the ideological bases for the pro-choice movement originated with Nazi collaborators. This is not hyperbole, I'm not trolling, it's a historical fact.

    Yes... I mentioned the Nazis. Right.

    It's not that I really believe all pro-choice people are in league with the devil, but merely that they are unaware of the larger, underlying issues in the debate.

    The issue of abortion hinges on the definition of what it means to be human.

    In my other post I argued that it hinges on which beings qualify for individual rights, and I decided that all sapient beings deserve the right to life. I explicitly extended this right far beyond the human race. Not based on superstitious, unfalsifiable claims like the presence or absence of a "soul" but the quality of sapience that can (at least in principle) be detected.

    The sapient alien question is hardly compelling because a moral evil does not require damaging a human being. In Islam, it is morally wrong to mistreat an animal. If the sapient alien would qualify as an animal, we could safely say killing one would be morally wrong, without ever addressing the issue of whether they possessed a soul, were sentient, intelligent, loving, caring, etc...

    Seems like you're saying sapient aliens would be on the same moral level as cows. Mistreating one would be morally wrong, but "humanely" slaughtering it for food is presumably okay. I strenuously disagree.

    So instead, they simply avoid the debate, and their proponents are left in a rather untenable position of being able to do nothing more than assert, without reason, the supposed correctness of their cause.

    Like when some people assert that homosexuality is immoral because a straight father really loves his son? Or how some people assert that abortion should be illegal because they watched a person die unexpectedly? I agree, both of those instances seem like enormous leaps of logic that are very good examples of assertions not backed up by reason.

    As an example, I'll use homosexuality. According to Judaism, Islam, and Christianity, it's wrong. But why?

    Because people are fundamentally herd animals, and fear anyone who's different. This prejudice affects everyone, even the people who wrote those "holy books."

    I honestly didn't know the answer. Why would God care if someone found sexual pleasure in a unique way? He wants us to be happy, right? I didn't find out until after I had married and had a child. ... I had *no idea* being a father could be so rewarding. But most homosexuals will never experience this joy, let alone know it exists.

    Neither will single people, couples who can't have kids, or couples who choose not to conceive. But they're not all sinners because of their choices (depending on the religion in question and the method of contraception.) Also, homosexuals can have children through surrogates and should certainly be able to adopt children.

    In a similar manner, someone afflicted with homosexual desires, often simply can't understand why they would resist temptation.

    Because God creates people with homosexual tendencies (even though He wants us to all have children) just to watch them squirm. If they manage to suppress the desires He gave them, they don't burn for all eternity. Hey, this sounds plausible and reasonable. Where do I sign up?

    The first time I met a homosexual, it was immediately apparent to me that they were undergoing an epic internal struggle, the least of which concerned their sexuality. Yet, to them, this condition has persisted for so long it felt "normal" And without the ability to defer judgment to another's experience, they saw no reason to change. Without any understanding that things could be better, they thought of my position as merely trying to take away what little happiness they did posses.

    I'm just kidding. I don't really believe that. But it was silly of me to justify a position with such a subjective anecdote, wasn't it? Maybe calling homosexual desires "afflictions" makes you tend to see more of an internal struggle than can be traced back to the fact that gays live in a world that hates and harms them for no good reason?

    Having actually seen someone die unexpectedly, it is very clear to me that all human life is valued by God. Until that happened, the abortion issue for me had been largely a philosophical exercise. It wasn't until I witnessed the death of a human being that my mind changed dramatically. But I realize that most reading this have not had that experience.

    Maybe it's very clear to you how that conclusion follows from witnessing an unexpected death. And maybe all the atheists in the world just haven't seen anyone die unexpectedly. (I wonder what the odds of this are?)

    Or maybe grief affects everyone differently, and doesn't imply anything about any deity.

    In fact, most of us will never have all of the experiences which shaped the Torah or the Bible. We simply have to trust that these tenets of morality were written down and copied throughout the ages because enough people recognized the value and truth in them.

    Individual rights aren't directly linked to genetics. Otherwise it would be perfectly moral to kill a sapient alien. He's not trying to say fetuses aren't human in a biological sense, but rather that mere human DNA doesn't necessarily confer individual rights.

    Does that mean that persons with mental defects are somehow not human?

    Again, they're biologically human. But morally, a person who suffers irreversible brain death is no longer sapient, so our laws (correctly) allow families to "pull the plug." This is the most extreme case, of course, and it's common for this position to be used as a strawman position: "Pro-choice means that anyone with an IQ below X should be killed!"

    This couldn't be farther from reality. Most people recognize the need for shades of grey. For instance:

    How about people with alzheimer's and very young born children? Are they inhuman because they lack some of these qualities you speak of? No sir... you are unequivocally wrong.

    People with alzheimers shouldn't be given driver's licenses, nor should they have access to firearms or heavy machinery. Very young children don't have the right to vote or enter contracts. But only a lunatic would say that they have the same rights as a brain-dead vegetable. Shades of grey are necessary.

    A dog has the mental capacity of a 2 year old child yet you would not say that the line was drawn at that point; the dog is thought of being less than the human despite similar mental capacity.

    For a very good reason; dogs don't ever progress past that point. Humans do.

    You value human life on a fairly arbitrary scale that favors your opinion but has little to do with reality.

    All moral decisions seem arbitrary to me, in the sense that they can't be falsified. But I also arbitrarily think that all sapient beings have the right to life. This includes all humans except for those without the capacity for sapience (e.g. fetuses prior to the development of a "reasonably" complicated brain, and people who have suffered irreversible brain death.) It also includes sapient aliens, genuine artificial intelligences, and possibly cetaceans, cephalapods, and some of the other great apes.

    I haven't conclusively figured out where to put the boundaries for individual rights. Anyone who thinks these issues are simple is either naive or a genius on a level I'll never be able to reach. Morality in the real world is messy and arbitrary for everyone who hasn't locked himself into a moral system prescribed by an omnipotent, omniscient deity.

    Yes, Faraday rotators are used in optics labs to rotate the polarization of polarized light. I didn't mention either of these effects because they're irrelevant in this context. Sunlight isn't polarized, so rotating its polarization doesn't do anything. Plus, the magnetic fields required for a measurable rotation are far stronger than the Earth's field.

    That's what I'm thinking too. GCR intensity is highest when sunspot activity is lowest, generally modulating on an 11 year cycle. But solar irradiance also varies at the same frequency; the Sun is actually (~0.1%) brighter when more sunspots are present, contrary to intuition.

    If tree growth between 1953-2006 really is highest when sunspot activity is lowest, that implies trees grow faster when the Sun is very slightly dimmer. Weird. Their diffusion explanation makes sense, but as they note this cloud condensation effect is supposed to be a very small effect. Perhaps it's just large enough to be noticed in these proxy data, though. I agree, however, that a link to solar irradiance is more intuitively appealing, and it's not immediately obvious how it could be ruled out.

    I'd bet they've already considered this issue and ruled it out, possibly by using satellite measurements of solar irradiance and solar wind over the last few decades. They're supposed to be tightly correlated, but if the solar wind varies even slightly differently than solar irradiance it should be possible to see which is causing this variation in growth rates.
