Talking Science and God With the Pope's New Chief Astronomer

sciencehabit writes: On 18 September, Pope Francis appointed Jesuit brother Guy Consolmagno as the new director of the Vatican Observatory, which employs a dozen astronomers to study asteroids, meteorites, extrasolar planets, stellar evolution, and cosmology. The observatory is based at the pope's summer residence south of Rome and operates a 1.8-meter telescope in Arizona, where the skies are clearer. Science Magazine chatted with Consolmagno about a variety of topics, including whether God gets in the way of doing good astronomy. Consolmagno said, "First of all, I want to provide space for other astronomers to do their work. And I also want to show the world that religion supports astronomy. It is often religious people who most need to see that; they need to know that astronomy is wonderful and that they shouldn't be afraid of it. I often quote John Paul II, when he said [of evolution] that "truth cannot contradict truth." If you think you already know everything about the world, you are not a good scientist, and if you think you know all there is to know about God, then your religious faith is at fault."

      Sorry I don't care how cool this guy comes off, being a scientist and believing in fairytales is a conflict of interest for me.

      So I suppose you ignore the contributions of all of these Catholic scientists, including all of these Catholic clerics who have made prominent scientific contributions (including the founders of many scientific disciplines)?

      I'm no defender of the Catholic Church or of overzealous religious idiots in general. But your attitude is a pretty extreme version of the so-called Conflict Thesis, which is a product of 19th-century historical revisionism by a few ill-informed historians who wanted to claim that religion has stood in the way of science throughout history. This viewpoint has been widely discredited by modern historians of science, as pretty much the opposite was the case. Many religious people throughout history have actually had very strong urges toward scientific investigation, since they seek to understand and appreciate the workings of "God's creation."

      On the specific topic of astronomy, the Jesuit order in particular has a very strong record of making significant contributions. Ever wonder why so many features on the moon were named after Jesuit scientists? It's due to one of the most influential treatises on astronomy from the 17th century, written by Jesuit scientist Giovanni Battista Riccioli. His Algamestum novum (1651) is largely forgotten today, but it made significant contributions to physics, putting much of Galileo's work on the laws of motion on a stronger theoretical footing.

      Perhaps the most interesting thing about Riccioli's treatise is his exhaustive compilation of arguments for and against the Copernican theory -- 49 for and 77 against. Riccioli's discussion is a model for modern scientific debate: he critiques bad arguments on both sides, though for him he ultimately comes out in favor of the Tychonic theory (proposed by Kepler's mentor, which was a kind of hybrid between geocentrism and heliocentrism). It must be remembered that in 1651 there was no clear empirical evidence in support of heliocentrism -- astronomers had been looking for things like stellar parallax and Coriolis forces in projectiles for decades and hadn't found them. (It wasn't until the mid-1700s, a full century after the Galileo affair, that Bradley's chance observation of stellar aberration finally put Copernicanism on a solid empirical footing. Until then, it was just gradually adopted because the math was easier. And it wasn't until the 1800s that many of Riccioli's arguments against heliocentrism were finally refuted by empirical evidence.)

      Imagine if we examined something like Riccioli's complex scientific debates as part of learning about the history of science, rather than our own scientific "fairytale" about Galileo triumphing over ignorant religion. In fact it was Galileo who was trotting out ignorant and weird arguments, while both mischaracterizing the strength of his own arguments and lampooning his opponents for their valid objections.

      (His only empirical "proof" for heliocentrism revolved around the tides, which required there to be only one high tide per day, and which would have to occur at noon. Obviously this contradicted empirical evidence... but, well, that was the best he had. He also rejected Kepler's empirically derived elliptical orbits and Kepler's empirically derived theory of tides caused by the moon -- because, well, circles are more cool and lunar tides didn't fit his theory.

      Yes, but you must take into account that at the time, if you were poor, the only way to get and education and learn a lot of things was to become a monk or a priest. Those got to learn to read and write, and had a lot of time to study and discuss with each other.

      This may have been true up to the 16th or 17th century or so. But by the late 1600s there were plenty of organizations and networks of scientists who were no longer part of the clergy.

      Your observation thus doesn't explain why so many scientists continued to join religious orders (or become scientists, despite being in religious orders) for the past 350 years or so. There are many major scientific disciplines founded in the 1700s or 1800s which came about with major help from Catholic clerics, other Catholic scientists, and Christian folks in general.

      So, if all those Catholic scientists would be alive today instead of hundreds of years ago, do you really think they would still have become Catholics or they would have been regular scientists (and by regular I mean not monks, priests or clerics)?

      This is an interesting question, but it's kind of a different one from what I was responding to. The question isn't whether science requires religion (I never said it does, and I don't think it does), but whether science is impeded significantly by religion... so much so that the parent I was responding to argues we should ignore a prominent scientist just because of his religion.

      I think that they were curious, intelligent guys who took the only option available to them at the time to expand their knowledge.

      That may be true for many of them, and I don't dispute that. But while being a religious person was still the default after 1650, there was plenty of secular training and scientific networks available to people who weren't ordained in the past three centuries or so.

      And yet those lists I linked to still contain many names from the past couple centuries. Why did they continue to take holy orders AND practice science? Your argument may apply to some, but certainly not to all.

      Again, I'm NOT arguing that religion produces better scientists (I don't think that's true), only that having religious beliefs has not historically impeded the progress of science as much as some people claim. (And, in fact, religious communities preserved knowledge and frequently encouraged the seeking of new scientific knowledge, as your argument acknowledges.)

Most recent example I read about was Buddhism, where in the late 1600s a handful of Jesuits had studied Buddhism in Asia for decades. Some other orders thought the knowledge they brought back (despite no Jesuit converting or otherwise waivering) was too threatening, and arrnaged for the pope to recall all the Jesuits in the far east. Some scholars have posited that some of the ideas the Jesuits brought back re Buddhism helped kindle the Enlightenment.

There is debate and personal opinion over what constitutes a severe defect.

If you mean debate as in one side talking science and the other arguing with nitpicks and ad hominems, it's still going on.

    The Earth's surface is warming up. That's based on observations, and is not open to question. There's no halfway reasonable way to interpret the data as anything other than not-particularly-steady warming. There's also observations like what's happening with polar ice (it's diminishing) and unusual weather patterns (although it has to stay unusual for a long time to constitute good evidence).

    Since the Nineteenth Century, we've known that carbon dioxide is a greenhouse gas, and that increasing its concentration in the atmosphere would warm the place up. Since 1850, the concentration has gone from about 280 parts per million to about 400, also not open to question. The change in the isotopic distribution of the carbon in the carbon dioxide (specifically, the amount of carbon-14) strongly suggests that the change is due to the release of old carbon, such as our burning of fossil fuels, and in fact we are burning sequestered carbon in amounts more than large enough to account for this change (suggesting that some of the carbon dioxide is being absorbed somewhere). There's no other obvious reason for the warming (climate scientists measure the sun).

    Given this, we have the rough outline of a theory that we're burning fossil fuels (also not open to question), which increases the carbon dioxide in the air, which warms up the Earth's surface. This is Anthropogenic Global Warming. There are no competing theories that match the observations. Such a theory would have to say that the carbon dioxide doesn't have its expected effect because of X, and the observed warming is due to Y. I'm not saying that couldn't happen, but I've seen no indication of what X and Y might be. Until someone comes up with such a theory, the science is pretty well settled. That doesn't mean it can't be unsettled if somebody has a bright idea, but at this stage that seems very unlikely.

    The next question is where it's going from here, and that's hardly settled, although the projections all indicate rising temperatures for some time if we don't do anything differently. Other questions include how much harm that's going to do, how much it'll be helpful, what happens if we vary the amount of sequestered carbon we burn, and what other means we have to change the global climate. Again, there's a lot of debate, although there's a general consensus that it will be be very expensive if we don't do something.

    The question of what we should do about it is political and economical, not scientific. It would be nice if the politicians involved would pay attention to the science, though.

    There's no argument about the science involved in abortion. We can determine all that.

    The question is moral, and there's no way to settle that scientifically. There is no scientific way to determine who has what moral rights, or how to reconcile conflicting rights.

    My position is that a woman has the right to not endanger herself for another's benefit. If my brother needed a kidney donation, and I was the only match, there's no law that says that I have to give him one. If I agree, I can back out at any time. I believe that in bone marrow transplants they kill the patient's bone marrow first, to prepare for the transplant. In a case like that, I have the legal right to agree to donate, wait until the recipient's marrow is destroyed so the recipient is going to die pretty fast without a transplant, and back out. Similarly, I don't believe a woman should be legally forced to support a fetus with her own tissue. This is why I believe that a woman should have the legal right to get an abortion. (This is not entirely a moral argument, and I strongly support some laws that make it possible for people to do things I consider immoral - free speech, for example.)

    We know how fetuses develop in the womb. We all know that they develop a heart, a brain (which starts having recognizably human activity after a while), and can move on their own at certain stages. There is no scientific controversy. What people seem to disagree about is at what point human rights come in, and that isn't a scientific question. Personally, I'm of the opinion that it isn't a human, for all moral purposes, until human-like brain activity starts. Other people disagree.

    I will point out that Roe vs. Wade didn't say that any pregnant woman could get an abortion at any time. It rejected legal limits on abortion in the first trimester. After Roe vs. Wade came out, I was expecting lots of states to pass laws that went up to the edge of what the Supreme Court said they could do, and it didn't happen. In fact, a law that forbade abortions past about four months (the time you mentioned) except for medical reasons wouldn't affect things much, as most abortions are well before that.

    The science of prenatal development is pretty well settled, and I haven't noticed anyone arguing about it. The ethics, and what the law should say, are not scientific questions and are subjects of debate.

    (By the way, I'm not aware of legal systems that treated abortions like murders. This means that those people who argue that abortion is murder do not have general acceptance or tradition on their side. I'm not saying they're necessarily wrong, although I am saying they're wrong, but it's up to them to argue for a reclassification.)
