Lawrence Krauss On the Pope's Encyclical: Not Even Close? 305

Lasrick writes: Lawrence Krauss muses on the hoopla surrounding Pope Francis' encyclical on climate change, and finds the document lacking: 'It is ironic that while the scientific community has long tried to raise warning signals and induce action to address human-induced climate change, an encyclical from the pope on this subject is being taken by many as an ultimate call to action on this urgent issue.'

    Three modes of persuasion/rhetoric identified by Aristotle are ethos, pathos, and logos.

    ethos is an appeal to authority or credibility
    pathos is an appeal to emotions
    logos is an appeal to reason

    Tthe pope's statement may have enough ethos with some audiences to make an impact.

  • I'm not Catholic, so I can't say I paid particular attention to the Pope's Encyclical. But I am also not particularly interested in what some atomic scientist has to say about the encyclical, or Catholicism, or climate change for that matter.

    The Pope holds a great deal of moral authority. Scientists not so much.

    I've read Laudate Si'. It's not really about the science, or arguing that AGW is true, or that biodiversity is being lost, or that pollution is killing people. It takes these things for granted but it does not marshall evidence per se.

    It's main point is that AGW, true or not, is evil and must be stopped, and it ties this into social teaching by associating the consumer culture of rich countries with the exploitation and immiseration of small, poor ones; mankind's moral obligation to protect the Earth, and it asserts baldly things like "man has no right" to push a species, any species, even the smallest plankton, to extinction (Francis actually mentions plankton).

    I don't hear scientists talk like this, and that's fine, it's probably not their place. But evidence isn't enough to actually move people to action, you do actually have talk about right and wrong, and why this thing is wrong and must be stopped. And Francis specifically argues against the idea that technology will one day solve this problem for us, to him the problem with the planet is 100% between people's ears, it has to do with the way modern people see the world as a resource to be exploited. Don't ask me to defend this, I think he's a little too pessimistic here, but it just continues the idea that his argument isn't about science, or technology, or even the material world, to him it's fundamentally spiritual.

    And he has a point; why should we care about climate change if the Earth if it's just a ball of dirt and we can just fly a rocket to another one? Science can tell us what the planet is and where it's going, but it can't tell us if that's a good thing or not. So does Krauss think scientists should hold more moral authority than a Pope? Is that the paradox here? Should scientists teach us right and wrong?

      Krauss brings up points that the pope doesn't _because_ of the pope's "moral authority". For example, Krauss makes the point that contraception is a must. A large world population is simply unsustainable without doing major environmental harm (and may simply be unsustainable, period). Needless to say, the pope couldn't really go there, although he has previously said that people should have fewer children -- never mind how.

      So, while I think the pope is doing much good, he is dangerously restricted by the very moral authority you mention. It's a double-edged sword.

        That's not true, the Pope goes there and totally disagrees with Krauss, Francis strongly condemns birth control and abortion. I agree I don't think that's workable, though I know what Francis would say: people should be fucking a lot less and only for procreation. This doesn't actually work in our culture, but as far as he's concerned the culture is the problem.

        • That's not true, the Pope goes there and totally disagrees with Krauss, Francis strongly condemns birth control and abortion.

          I would withhold judgement on that. I have a feeling that Pope Francis is going to lend some of the Church's authority behind the upcoming United Nations goal for zero population growth.

          Say what you will, the pope is not an idiot. He realizes that if you're going to head off disaster, you have to somehow limit population growth. My guess is that he's aware that very large families

            Not a chance. It would cause too much conflict within the church - even the pope is bound by the need to maintain some form of unity. If he does want to lend support to such a goal, he would have to do so without speaking of it openly.

            I've not even heard such a goal proposed before. The panic over population growth isn't as severe as it used to be, as it's b

            • I've not even heard such a goal proposed before. The panic over population growth isn't as severe as it used to be, as it's becoming clear that population does eventually level off naturally.

              When you say, "level off naturally" are you counting the starvation, displacement and epidemics?

          It's a little weird to say that the pope went there when in fact the pope took the position furthest from there, but that's semantics.

          Regardless, my point stands: the pope is restricted by his moral authority, and that's a real problem if he's leading the charge. (That said, I think the pope will do much more good than harm, but he could do so much more good if he would tell people to use condoms.)

          (I have another response to your original post, but I'll put it in another comment.)

        • The catholic church doesn't teach that sex is only for procreation. It teaches that procreation is a defining aspect of sex. Big difference. You're still allowed to enjoy sex all you want, so long as you have at least the possibility of procreation - but if you deliberately stop the procreative part from working then you are perverting sex into something unnatural, by taking away the purpose God intended it to naturally fulfill.

          Or, in the Church's own words from the Humanae Vitae, "If they further reflect,

          • If you read past the flowery language, you'll see that the Catholic Church's position is based on misogyny and the denial of women's rights to control their bodies. Mind you, so are most religions so don't think I'm bashing Catholicism particularly.

            Specifically in the Catholic case, it's also highly hypocritical. We have this "divine gift" from God, yet priests are not allowed to enjoy it --- all so the Church will inherit their property, of course, rather than natural living heirs. How conveeeenient.

      • by msobkow ( 48369 )

        Personally I think Krauss is just jealous that over a billion people will listen to the Pope and ignore him.

        Such is always true of the famous: they hold far more sway over the small-minded masses than the educated and intelligent arguments of scientists ever have or will.

      • ...although he has previously said that people should have fewer children -- never mind how.

        He may not say it, but the implication is there - don't have any fun.

      Science can tell us what the planet is and where it's going, but it can't tell us if that's a good thing or not.

      This is a very insightful comment, and I hope you don't get modded down by anti-religious morons. I don't care much what the pope says in his capacity as a spiritual leader, but he is a public figure that holds significant moral authority. I'm sure there will be a hundred posts in this thread about how "nobody should care about what the pope says," but the simple fact is that many people do care.

      And people do in fact need to CARE about the earth and the future of humanity if this is to be solved. That's a moral question, and not a scientific one. Why should we care about stuff that might not begin to have a REALLY bad impact in our lifespan? Some people are driven by concern about their kids and their grandkids -- others might just a commitment to humanity in some general way.

      But most people don't spend a lot of time constructing their own moral systems with philosophical rigor. They get their ethical sense from a number of sources, and for many religious people, this pope is an inspiration.

      So regardless of whether the pope argues for specific technological or economic solutions, he's arguing that we need to care and to care deeply. That may be important in swaying some people.

      I'm not sure I get what Krauss is complaining so much about. This is a theological and moral document, not a scientific blueprint to save the climate. The only actual complaint Krauss seems to have against the pope is that he refuses to change the church's opinion on birth control -- and I agree that the church's stance is ridiculous here, and I'm not going to defend it. (On the other hand, population control is only one piece of the climate puzzle.)

      But I have to say that things really go off the rails when Krauss starts quoting Steve Pinker, as in:

      The pontiff continues in the millennia-long Catholic tradition of vilifying technology, commerce, and ordinary people enjoying the fruits of material progress.

      I'm sorry, but Steve Pinker deserves to be called an idiot for saying something like this. Yeah, I know there's a sort of urban myth that grew up by atheistic activists in the 1800s about how the church has been against science since the dawn of humanity, but the reality is that the Catholic Church has long been a strong supporter of new technology, as well as new commercial progress. We're not talking about the rare ascetic monks here, nor are we talking about the AMISH (some of whom actually do villify technology, commerce, etc.).

      If you doubt my view on this, please spend at least a few minutes scanning the Wikipedia article on the history of the Catholic Church and science [wikipedia.org]. Aside from the Galileo affair (which I'll agree was a travesty), there's little evidence of the church being against scientific or technological progress -- for most of the past millennium, it has been a strong supporter of it.

      Steven Pinker proves himself to be ignorant, and Krauss misses the point. TFA's conclusion:

      Of course, these solutions leave the pope, and his church, with no special role. Thus, while I cannot fault the pope's intentions, which are presumably praiseworthy, his proposals are inevitably compromised if they adhere to doctrines that can thwart real progress, and that attempt to use prior theological arguments to address issues that need to be dealt with by focusing on not only real problems but also on real solutions.

      Uh -- the "special role" is the moral authority the parent already mentioned. The only "doctrine" mentioned by Krauss that "can thwart real progress" is birth control, which is admittedly a stupid policy, but it's generally not the first thing even most scientists start talking about in terms of climate change. And the "prior theological arguments" give an ethical

        Umm, religions can't tell us if it's a good thing or not either. Not in any objective sense of the word that we can all agree upon. Science can tell us the effects of our actions. Religion cannot. So science CAN tell us if what is happening is a good thing at least for any non-moral sense of the term good.

    • Science can tell us what the planet is and where it's going, but it can't tell us if that's a good thing or not.

      I disagree. You have to assume that people interested in their (and their offspring's) physical well being, and scientists darn well can tell us if something is good or not. (I'm not saying that's the only assumption you have to or should make, but those other assumptions can be factored in too.)

      However, the scientific answer is a much more complicated calculus. The pope can just tell people to stop destroying the environment. Science gives more nuanced answers like: this amount of environmental alteration

    • by khallow ( 566160 )

      It's main point is that AGW, true or not, is evil and must be stopped,

      When truth and reality don't matter, then right and wrong can be anything you want. It's just arbitrary bits to set.

      why should we care about climate change if the Earth if it's just a ball of dirt and we can just fly a rocket to another one?

      That's simple economics. Because you destroy a valuable asset and impose an unnecessary cost on yourself. You might as well ask why not burn your house down, if you can just move to another house afterward at great cost? Even asking the question demonstrates that one hasn't thought about the consequences any more than the people they supposedly are criticizing.

    • I don't think the pope holds any moral authority. No pope will until the church stops hiding the child molesters and hands them over, along with any files, over to the proper authorities for prosecution. While the church protects these scum from the law then they can't tell us what is right or wrong.

    • It's main point is that AGW, true or not, is evil and must be stopped

      Since millions will suffer in some way needlessly if it is not true (due to terrible misallocation of resources), why MUST it be stopped regardless?

      If that's the main point, then the whole paper means nothing in reality. It is simply the clearest sign yet that the "something must be done" cry around AGW is ONLY a religious matter, rather than scientific.

    • The Pope continues to actively shield child molesters. He holds no moral authority.

    Whoever thinks the pope is trying to pick sides in a political debate is either genuinely insane or has trouble forming simple logical concepts. Because on the scientific overall concept it's not even a debate. The best methods for combating climate change though, are still only scientific. Politics dosent even enter in until you try to implement those methods.

    Go ahead and mod me down but I'm really sick and tired of people thinking what they believe makes a crap in a biscuits difference to reality. Even though the popes statement may be lacking its a great step to get hundreds of millions of stupid people to start acting responsibly and be aware of the issue. It's just so ironic that it is a belief in faith, with no foundation in factual reality, that brings awareness to the factual reality we as a species are facing.

    I really enjoy Lawrence Krauss, and Richard Dawkins, and, alas, Christopher Hitchens etc. I am an "anti-theist" and someone who has absolutely no belief in god. That being said, I have spoken at my wfe's church, cooked for their dinners, and was friends with the last pastor. He and I accepted that we had no common ground in the spiritual world, but we both agreed that community is good, and that creating friends and being good friends and neighbours is good. How could that not be? I stood up in front of the church and said I was an Atheist and that I enjoyed the community. I got applause. This is a true story.

    Lawrence, Richard, an others obviously need to continue the Atheism work that they do, but they also need to understand that this was a HUGE movement by the catholic church. HUGE. The pope is a chemist. A scientist. If you judge this pope by his words and his actions, he may be the sort of man that can lead a sizeable portion of the world population in a better direction.

    I think "Atheism" and "Climate Change" are separate. If this pope did not do enough, reach out. He isn't the nazi-youth that was there previously, this is a man trained in chemistry and seems earnest. I think this is the best chance science and a major religion have ever had to work together to address a real problem facing human kind. Rather than snipe at the pope for not going far enough, holy shit guys, 1 billion people claim to listen to this guy, convince him to do better.
