The Tale of a Comet

It is well-known that people who lived before the Enlightenment were hopelessly superstitious. They believed, for example, that "odd" occurrences in the sky were omens signifying that odd occurrences would soon happen down here on Earth. The most blatant example of this took place when Halley's Comet appeared in 1456. While it was still visible, the siege of Belgrade by the Turks began; thus it was feared that this portent in the heavens had some relevance to the battle. Halley's Comet so upset Pope Callistus III that he resorted to drastic measures: he excommunicated it.

For years, this story was repeated as an example of how absurd and superstitious religion is, especially when contrasted with science. Carl Sagan referred to it in his book on comets. But of course, you know where I'm going with this: it didn't really happen. The story appears to have been popularized by Pierre-Simon Laplace at the end of the 18th century; Laplace, in turn, apparently got it from Vitæ Pontificum, a 15th century work, by Bartolomeo Platina. The Catholic Encyclopedia article on Platina dutifully translates the relevant text as follows:

A maned and fiery comet appearing for several days, while scientists were predicting a great plague, dearness of food, or some great disaster, Callistus decreed that supplicatory prayers be held for some days to avert the anger of God, so that, if any calamity threatened mankind, it might be entirely diverted against the Turks, the foes of the Christian name. He likewise ordered that the bells be rung at midday as a signal to all the faithful to move God with assiduous petitions and to assist with their prayers those engaged in constant warfare with the Turks.

Now there are a couple of things to note right away. First, there is no mention here of the Pope excommunicating the comet. Second, while the Pope had indeed issued a papal bull calling upon people to pray, and while Halley's Comet did appear in the sky at about the same time, there was simply no perceived link between the two. The bull doesn't even mention the comet. Platina just tied two events together that had no connection.

Laplace took Platina's account and suggested that Callistus sought to exorcize Halley's Comet -- and I can't help but wonder if he intended this as a metaphor. Regardless, subsequent writers took it literally, and replaced "exorcize" with "excommunicate" since all those religious terms mean the same thing anyway. The final paragraph of the afore-mentioned article summarizes this development well.

Of course, no doubt there were people who thought Halley's Comet had something to do with the siege of Belgrade. That's the kernel of truth in this story. For that matter, it may very well be true that people in the 15th century were in general more superstitious than people today tend to be. But we still have astrology. Most newspapers print the horoscope every day.

What interests me is how people who hold themselves up as skeptics were taken in by such a ridiculous story as this. Carl Sagan was, by any account, a brilliant man. Yet he uncritically repeats an urban legend in order to show how other people are gullible. What this shows, I think, is that there are no true skeptics. People are only skeptical of things that they want to be skeptical about.

For example, in his book My Life Without God, William Murray describes how his mother Madalyn Murray O'Hair would tell groups of atheists that religious people were so stupid that nobody realized sex led to pregnancy until the 19th century. This is difficult to write without chuckling, but her throng of skeptics bought it. O'Hair herself attended seances, and believed she could talk with dead people. Murray wrote that, as far as he knew, his mother never tried to reconcile this with her belief that there is no afterlife. The skepticism with which she and her fans approached religion was obviously not consistently applied.

The point of all this is that we should be skeptical of our skepticism. The reason why an intelligent person like Carl Sagan could be taken in by such a silly story as a Pope excommunicating a comet is because it fit with his views on the nature of science, the nature of religion, and the relationship between the two. Madalyn Murray O'Hair and her followers were completely contemptuous of religion and religious believers, so any claim that justified this attitude, no matter how insane, was plausible to them.

I have different biases: I am skeptical of the claim that science and religion are opposed to each other. This makes me prone to accept stories that seem to affirm this bias without showing them the same level of critical analysis that I would show to a story that contradicts it. I have to examine myself to determine, as far as possible, what my biases are, and how they might be influencing my beliefs.

Islam, Christianity, and Euthyphro

Euthyphro is one of Plato's dialogues which presents us with a meta-ethical dilemma that has been addressed throughout philosophical and theological history (meta-ethics being the study of the ground or foundation of ethics). In this debate, Socrates asks Euthyphro why God assigned the particular moral laws he did, such as to not commit murder or adultery. The problem this creates is that if God assigned these laws because they are good in and of themselves, then there is a "higher" reality than God, and God commands them because he must align himself with this reality just as much as we do. God, in other words, is not absolute; neither the ground of morality nor of reality. But if we say that these laws are not good in and of themselves, then these laws are simply arbitrary, and God could have made them differently. The "good" would have been to commit murder and adultery if God said so. In this case, God is not intrinsically good because the appellation of "good" is entirely arbitrary (this is the position that Euthyphro takes in the debate).

Traditionally, Christianity has split the horns of this dilemma. Moral laws are intrinsically good, not arbitrary. But their goodness is not derived from something outside of God; rather, they are derived from God's own intrinsically good nature. The ground of morality, in other words, is identical to the ground of reality. The error of the Euthyphro dilemma is that it tries to put the two concepts -- the goodness of certain acts and God's command of them -- into a cause-and-effect relationship with each other. If the goodness of these acts is what causes God to command them, then they are higher than he. But if his command of them is what makes them good, they are arbitrary. Neither, however, is the case: these two concepts are both effects from a common cause, namely, God's own nature.

Now, as far as I can tell, this option would be available to any general theistic position. But in my (admittedly limited) knowledge of Islam, Muslim theologians have not availed themselves of this resolution. A core doctrine of Islam is that God is completely transcendent; that is, he transcends even our moral and rational categories. God may give moral commandments, but ultimately, they are not expressions of his nature -- if they were, then he would not transcend them. Since they have their origin in his command of them, but not in his nature, they could have been different, and are therefore arbitrary, as Euthyphro thought.

Thus, in the Qur'an, God is represented as capricious. For example in the battle of Badr, God had told Muhammad (indirectly -- since God is completely transcendent there is no direct communication between him and humanity in Islam) that he would outnumber his enemies. When Muhammad's army got there, they found to the contrary that the enemy outnumbered them; but there was no way to avoid the battle at that point, and the Muslims ended up winning anyway. Later, when Muhammad asked why God told him that they would outnumber the enemy at Badr when they didn't, the response in the Sura of the Spoils of War is essentially, "If God had told you the truth, you wouldn't have gone".

Or take the Qur'an's explanation of Jesus' crucifixion, which Muslims deny: God made it seem that Jesus was crucified, but he really wasn't. Islamic tradition explains this by claiming that God put the image of Jesus on someone else (sometimes thought to be Judas Iscariot), and this person was crucified instead of Jesus. In any case, God made things appear differently than they really are in order to accomplish his objectives. So it seems that Islam has pitched its tent with Euthyphro, by accepting that the moral laws are good because God commands them, and that they are thus arbitrary.

In contrast to this, the God of the Bible cannot lie; not that he merely does not or will not, but he cannot. Unlike Islam, in Christianity morality and rationality are two things that put us in touch with God, because of their origin in his nature. God does not transcend morality and rationality, he is their very ground. That's part of what it means to say that we are created in his image -- there is a connection between humanity and God, even after the fall. We are created in his image because we have the capacity for morality and rationality. There's more to it than that of course, but that's at least some of it.
