Re: DeLong on health insurance reform
John said: Yes, but it's not the whole story. It is not my whole post, either, since you cut the quote off early. I know it wasn't your whole post let alone your whole argument but it was enough for me to hang my toy example from. I suspect you double-counted the 9 possibilities where each person gets 1 item, and also the 6 possibilities where 1 person gets two different items. 36 - 9 - 6 = 21. My reasoning in more detail was that one dollar can be spent in six ways: (Alice, burger); (Alice, fries); (Alice, shake); (Bob, burger); (Bob, fries); (Bob, shake) The spending of the two dollars is independent so the total number of ways they can be spent is 6x6 = 36. However, I think that you're right as burgers are indistinguishable from each other, as are portions of fries, as are shakes, at least in a simple toy model. I was counting the case in which the first dollar buys Alice a burger and so does the second as two cases rather than one. As you said, there are six such cases that I've counted twice. I was also counting cases in which the first dollar buys Alice a burger and the second buys Alice fries as distinguishable from the one in which the first buys her fries and the second a burger. If they're indistinguishable it's clearer to describe them as "Alice doesn't have a shake" or whatever and there are actually only 3x3=9 cases rather than the eighteen that I counted. So the correct count is 36-6-9 = 21, as you calculated. Your method of counting has the virtue of being more elegant as well as the greater virtue of being correct. Thanks for the correction. Also, if each person chooses one of 7 uniformly, the 28 outcomes will not be uniform: for example, Bob with 2 burgers will be half as likely as each with a burger. It seems that the outcome will be less predictable, more randomized. Yes, that's true. There will be some quite odd cases in which Alice buys Bob a burger and vice versa too (and similarly for the other two products). Do you think Nick would argue the same thing (Alice must give everyone a dollar) if Alice had $10 and 9 others had no dollars? What if Alice had $20 and ten others had $2 each? What if, instead of dollars, we had coupons for a medical treatment to extend life by a year? Must Alice give up years of her life? What about contracts to provide 1 year of manual labor to XYZ corporation? If Alice was liable for 2 of those contracts, and Bob was liable for none, must Bob take 1 of the contracts? What would you guess Nick would argue? I think that in the cases with the money or the coupons Nick would argue that Alice should be made to give to the others, but not in the case with labour contracts, but I suppose we'll have to wait for him to give his opinion. Of course, not all years of extended life have the same cost in expended resources so that example's a bit strange. Similarly, the opportunity cost of making different people engage in manual labour varies wildly. Rich ___ http://mccmedia.com/mailman/listinfo/brin-l_mccmedia.com
Re: DeLong on health insurance reform
John said: Say I have two $1 bills. I could choose to go to McDonald's and buy a burger and fries. Now someone takes one of my dollars. Now I can only buy a burger, or fries, but not both. My choices have been limited. My freedom to choose has been limited. That is obvious. Yes, but it's not the whole story. Suppose that Alice has two $1 bills and she could choose to buy a burger, fries or a shake, each of which costs $1, and further suppose that Bob has no money. Then Alice could choose from one of 36 possible futures (as each dollar could supply one of {burger, fries, shake} to one of {Alice,Bob}, so she could choose, for example, a burger for herself and fries for Bob or a burger and fries for herself). Alice has quite a lot of freedom, but Bob has none. Suppose George insists that Alice gives $1 to Bob. Then Alice can't choose any of the 36 possible futures. The most she can do is to pick one of six "partial futures", for example the one in which she has at least one burger. Bob can also choose one of six partial futures, for example the one in which he has a shake. The outcome is that Alice and Bob collectively choose one of the 36 total futures. Alice's freedom has been curtailed a bit, but Bob has been given some freedom in compensation. I guess that you would argue that Alice's two $1 bills are hers, and that if she wants to use them to give Bob some freedom she could choose to give one or both to him but that George isn't justified in forcing her to. I further guess that Nick would argue that it's more fair for George to make Alice give the dollar to Bob as the gain in freedom for Bob outweighs the loss of freedom for Alice.

That they are unqualified will never occur to them. Sadly, there are a large number of people who will do just that. For example, a few years ago I wrote an article on faster-than-light communication and causality in special relativity in which I showed as clearly as I know how that the existence of a communication system whose signal is instantaneous in the frame of a transmitter and receiver that are at rest with respect to each other can be used to violate causality. This is an unambiguous prediction of special relativity, and is a special case of a more general violation of causality by faster-than-light communication in the theory. Furthermore, it doesn't rely on anything except the two postulates of special relativity. (General relativity doesn't change the prediction; it just makes the demonstration more difficult.) Nevertheless, the article spawned an interminable comment thread in which I've repeatedly been accused of being an idiot on the basis of other people's intuition about how time must be. Unfortunately, special relativity has been supported (in the form of quantum field theory, which combines special relativity with quantum mechanics) to something like one part in 10^14 whereas the vague intuitions of non-physicists about time and causality are presumably on less secure footing.

IIRC, the Chinese empire > lasted > about the same length until it was overtook by the Ghengas > Kahn...who's rule > ended up merging into that empire. It may be an aside, but both of those statements are misleading. To begin with, Constantine reunified rather than splitting the administration of the Roman state. The history of the separation between West and East bears closer examination. Under the Republic, the Romans had a long history of the division of the supreme magistracy, first between two consuls and later into first an ad-hoc and later a formalised "triumvirate". This tendency briefly re-emerged during the second century with the co-imperium of Marcus Aurelius Antoninus and Lucius Aurelius Verus, which enabled the presence of emperors at several trouble-spots concurrently. During the troubled third century this need for divided absolute authority became even more pressing and was formalised by the emperor Diocletian's institution of the "tetrarchy", in which there were two senior emperors ("Augusti") and two junior emperors ("Caesars"). It was Diocletian's intention that the Augusti should periodically abdicate in favour of their junior colleagues who would in turn appoint two new Caesars from the best men of the state. The succession of the emperors would thus be regularised, putting an end to the cycle of rebellion and civil war that had plagued the empire for fifty years. Unfortunately, it didn't work like that, as sons of the Augusti who had been passed over in favour of new, unrelated emperors, asserted their supposed hereditary rights, alternative centres of power crystallised and a new phase of civil wars began. The ultimate victor was Constantine, who became sole ruler of the Roman empire in 324. Before Constantine, there had been many temporary Roman capitals - for many decades the capital had effectively not been Rome but wherever the emperor was. Under the tetrarchy, for example, the capitals of the Augusti had been Nicomedia in Asia Minor, Mediolanum in northern Italy, Sirmium in what's now Serbia and Augusta Treverorum (modern Trier). One of Constantine's several innovations was the establishment of a permanent new capital at Constantinople. Rather than this city being the capital of an "Eastern Roman Empire", it was the capital of the whole empire. Even during periods of division of the imperial authority, the empire itself was seen as a unitary whole and the usual procedure was for edicts to be issued in the name of all the current emperors and to be enforced across the Roman world. It's commonly held that the final division of the Roman empire occurred in 395 at the death of Theodosius I, at which Honorius became emperor in the west and Arcadius in the East. From then until the extinction of the western dynasty in 476 there was always an emperor in Constantinople and another usually in Ravenna. However, even as these two centres of power solidified, the Roman world formally remained whole. The two emperors provided each other with military assistance even as late as a major joint naval expedition against the Vandals in 468. Even the man sometimes seen as the last fully legitimate western emperor, Julius Nepos, was appointed by the eastern emperor Leo I. Furthermore, following the overthrow of the last western emperor, Romulus Augustulus, many of the Germanic successor rulers claimed to be ruling not as independent kings but as representatives of the emperor at Constantinople. As for when the Eastern remnant of the Roman empire fell, I think there were two very clear periods during which large swathes of territory were lost and the character of the empire deeply changed. The first was during the lightning conquests of the Muslim armies in the seventh century, which cut away from the empire the ancient Roman provinces of Syria, Palestine, Egypt and North Africa. Augustus might well have recognised the sixth century empire of Justinian as a successor, however much transformed by the passage of centuries, to his own; but the Byzantine empire of Heraclius and his successors was a different world. The second major collapse occurred with the defeat of Romanus Diogenes by the Seljuk Turkish sultan Alp Arslan at Manzikert in 1054. (The Seljuk sultanate was a successor to the Arab Caliphates that had inflicted the earlier defeats on the Byzantines.) In any case, much of this is a distraction from the central questions: what endured for those 1500 or more years, and was it totalitarian. In my view the main continuity was that of the administrative bureaucracy created by the Romans, despite the changes at the highest levels of power, the shifts

I'm pretty sure that the answer is (a). Interactions in quantum field theory can be written as sums of Feynman diagrams, each of which is made up of lines representing particles and vertices at which the particles interact. Each type of force has characteristic vertices. For example, the electromagnetic force has a vertex with two charged particles and a photon. This can either represent a single charged particle emitting a photon or a particle and its anti-particle annihilating to form a photon. So, for example, an electron and a positron can annihilate at a vertex forming a photon. (To conserve energy and momentum, you need at least two vertices resulting in two photons in the whole diagram.) Thus, no interaction vertices means no interaction, and hence no reaction and no particle emission. Rich ___ http://www.mccmedia.com/mailman/listinfo/brin-l

How do they change with time? Which factors help some prosper when others fail? How do ideas flow between them? - Sociological questions, such as those about the benefits or otherwise to society of religions, the dynamics of religious communities and so forth.

I'm very aware of my bias towards the Romans in my reading about history and one of my intentions for next year is to read several histories of the Persian empires to compensate. Having said that, I think that it's largely Rome that was to blame for the wars against the Parthians and Sassanids. The motivations for the Romans were mixed: the prestige attached to military conquest, the promise of plunder from the famously wealth East, the almost pathological desire to secure the Republic against threats from its few peers, and later the religious opposition of Christianity and Zoroastrianism (the latter of which was much more tolerant of other religions than the former). The war that started over half a millennium of intermittent conflict between the two powers was engineered purely so that Crassus could have military exploits to rival those of his fellow triumvirs. Marcus Antonius' Parthian expedition had a similar motive. And so it went... I don't think the Parthians wanted revenge for Alexander's conquests. In general they were fairly philhellenic and during their expansion they largely absorbed the Greek administrative system and the Greek elites of the crumbling Seleucid empire. Maybe such a motive was more likely for the Sassanid monarchy, but again I know so little about Persia that I'd hesitate to say. By the way, I can't remember if I've mentioned it here before but you might be interested in reading the first of my (slowly) ongoing series on the period from the crisis of the third century to the Arab conquests, "The Pirenne Thesis and the End of Antiquity": http://www.theculture.org/rich/sharpblue/archives/000140.html With a little luck I might find time to finish the second part soon!

Interestingly, I wouldn't even describe the Empire as "Byzantine" until after Heraclius. Whereas Justinian's empire in the mid sixth century was manifestly Roman, and Justinian saw himself as the heir of Augustus and Diocletian, Heraclius clearly didn't. The near terminal crisis of the empire during his reign changed the entire character of the empire, and provides what seems to me the most natural break-point between "Roman" and "Byzantine" (although, of course, there are many continuities that span the divide). But let me say something about that crisis... For the whole period of the Dominate, from the end of the troubled third century until the final war between Rome and Persia, the military strategy of the Romans was dominated by the Persian frontier. Even during the period of the fall of the western part of the Empire, the bulk of Roman forces were tied up in the east. (Indeed, if not for this the western provinces would almost certainly not have fallen, and if the threat of Persia had receded then the recovery of the west by Justinian's generals Belisarius and Narses would probably have been much more complete.) For much of this period the massive Roman forces and fortifications along the frontier preserved the peace although there were limited wars in the buffer regions. During the century and a half between the fall of the west and the final war, there were relatively small wars during 502-6, 526-32 and 540-57 (a more serious pair of overlapping wars on different fronts during which Antioch fell to the Persians). Then in 602, the apocalypse that the balance of military might between the two powers had postponed for centuries finally broke out. The Romans had been weakened by another bout of civil war, military unrest and the invasion of the Balkans by the Avars. The Persian king Khosrau II took advantage of this weakness and invaded Roman Mesopotamia. In 608, Heraclius, the son of the Exarch of Africa, rebelled against the emperor Phocas, whose rule had been generally disastrous, and took Constantinople in 610. The renewed civil war in the Roman Empire further strengthened the position of the Persians, who invaded Syria, taking Damascus in 613, Jerusalem in 614 and conquering Egypt in 616 (it remained under Persian control for a decade). At the low point for the Romans, the empire in the east was reduced almost to the city of Constantinople itself: the Avars controlled the Balkans and the campfires of the Persians were visible just across the Bosphorus. The imperial government came within a whisker of abandoning the city and moving the capital to the safety of Carthage. I don't think anybody at the time can have expected anything except the imminent dissolution of the Roman Empire. Remarkably, that's not what happened, largely because of Heraclius himself. Unlike most of the later Roman emperors his charisma could inspire immense loyalty and courage in his troops and he turned out to be something of an organisational and military genius. He totally reformed the administrative and military structure of the Empire (and along the way replaced Latin with Greek as the official language of the imperial government). His reorganisation largely endured for eight centuries, which is why I consider him the first Byzantine emperor. Heraclius was also the first emperor to lead his troops in person for over two hundred years, and his campaigns between 621 and 627 were spectacular indeed. A combination of strategic and tactical brilliance and skillful exploitation of weaknesses in the Persian political system brought the Persian empire to its knees, plunging it into a series of crises that fatally weakened it. By the end of the war, the Romans had recovered all the territory they'd lost to Persia, but they were territories ravaged by a quarter of a century of foreign occupation and war. It was only seven years after the end of this last war between Rome and Persia that the armies of Islam erupted from Arabia. By that time Heraclius had fallen into terminal illness, and his generals failed him. Syria fell to the Arabs in 634, the Persian army was defeated in 636, Armenia and Egypt were conquered in 639, Africa in 642, Persia itself in 651...

Re: "Someone Must Tell Them"
Dan said: I really don't see this. For example, with AQ, the evidence is that they see the lifestyle of the West as decadent and evil, and the dominance of the West to be anathema to the proper order of things. My take is that the radical fringe of Islam is a sort of cargo cult. I think that fundamentally most people everywhere want prosperity and security for themselves and their families, and a sense that they're respected. The Islamic world once had all of those things. For the period from, say, AD800 to AD1400, Islam was one of the world's two most powerful civilisations (especially in the period when an expansionist Abbasid Caliphate skirmished with China's T'ang dynasty in central Asia). Indeed, even at the end of that period the great conqueror Temur-i-Lang thought that the important parts of the world were the Islamic states, India and China, and that Europe was too insignificant to bother conquering. Since then, the position of the dar al-Islam relative to the European civilisation has clearly shifted dramatically in favour of Europe and its overseas extensions. For the last two centuries, the once mighty Islamic world has suffered military reverses, the dismemberment of its last major empire, and near total colonisation by Western powers. The essential problem facing us today is that the model used by the radical Islamists to explain this immense political, economic and social cataclysm is utterly incorrect. The reason for the explosive expansion of the Arab armies was partially the unity given them by Islam, but was mostly the weakness of the Roman and Persian empires in the aftermath of their final apocalyptic war. Following that expansion, the reason for the prosperity of the Islamic states in the AD800 to AD1400 period wasn't their adherence to strict Islamic laws - in fact most of them were pretty lax about applying such things - but their position straddling the trade routes crossing Asia. For most of that period, the most important trade routes in the world were the "silk roads" that ran from Chang'an in the east through the Tarim basin or the northern foothills of the Tien Shan mountains, through Samarkand and the other great trading cities of Central Asia, into Persia and Iraq and then to the Levantine ports on the Mediterranean and south into Egypt. The power and wealth of Islam were the result of its openness and encouragement of trade. Then later the Atlantic states of Europe mastered the art of oceanic navigation, discovered America and bypassed the silk roads by opening up direct contact with India, the East Indies and China. As transcontinental trade dried up, so the Islamic world supported by that trade began the long, slow decline from its brilliant apogee into today's decrepitude. Unfortunately, the radical Islamists don't see it that way. One of the characteristics of Islam is that the success of Islam-the- religion and the success of Islam-the-states are closely tied together in the minds of many Muslims (certainly more so than the two kinds of success are in the minds of Christians). Attacks on the dar al-Islam are easily seen as attacks on Islam itself, and failures of the dar al-Islam are easily considered the effects of moral failings on the parts of the people. In my opinion, the radical Islamists have built a cargo cult on this basis: they see the recapitulation of the forms of Muslim behaviour from the great days of Islam as the key to regaining prosperity, security and respect. But the shallow aping of forms misses the deep reasons for the success of Islam. This is seen most clearly in the case of the Taliban, whose viewpoint seems to be that the relative poverty and impotence of Afghanistan isn't due to the withering of trade through the region (which once supported some of the most magnificent and rich cities in the world) or other more recent but secondary historical factors but is caused by the people not being strict enough or literal enough in their interpretations of the Koran and application of the Sharia. It's also apparent in the web of international Islamic terrorism, which seeks to regain the greatness of the Islamic world through fantasies of recapitulating the heroic military actions of the first armies of Islam against the infidels. Unfortunately, although these attitudes are clearly idiocy of the first order to most of us, they are pretty seductive to certain groups of people both inside and outside the Islamic world. Equally unfortunately, they are doomed to failure and generally deleterious to the well-being both of Islam and the dar al- Islam. Quite how we can convince people in the regions where the failure of the Islamic states is most total that the things they ought to be emulating from the glorious past of Islamic are openness to trade, toleration, meritocracy, egality, respect and encouragement for

For us to lose our freedoms in the name of a little illusory safety. For us to be _not_ US. One of the most striking things about the July 7 attacks was how utterly unterrified we all were. I know people who were very close to the bombing attacks and their response was uniformly calm and practical. In fact, those attacks seemed to cause more anxiety and fear on the other side of the Atlantic than they did here. I think a positive first step would be switching nomenclature from "terrorist" to "idiot", for calling them terrorists tends to suggest that we're terrified of them or at least potentially so. Besides, news stories that start "A group of idiots demonstrated their stupidity by blowing themselves up..." are so much less glamorous from their point of view.

Re: Jobs, not trees! (Collapse, Chapter 2)
JDG said: Additionally, if my memory serves me correctly, Egypt went on to become one of the most important and productive provinces in the Roman Empire. Thus, it hardly seems to have been "depleted." In fact, Egypt was so productive that there were people who argued against its annexation as it was so much richer than the existing provinces that whoever controlled it would necessarily dominate the Roman state. This in fact turned out to be true. Octavian - later the emperor Augustus - took control of Egypt not as a new Roman province but as his own personal property, and this was an important part of his stabilisation of the turmoil of the collapsing Republic. Throughout the early Principate it remained an anomalous province controlled more or less directly by the emperor. Its importance was shown again a century later during the civil wars after the death of Nero, the key event of which was Vespasian gaining control of the Egyptian corn supply, which fed the city of Rome. The economic decline of Egypt only started almost a century after that, with Marcus Aurelius' suppression of an Egyptian revolt and the detrimental effects on the Egyptian economy of several years of warfare. I'm not sure why the solution of dividing Egypt into a number of smaller provinces took so long to occur to the Romans. Rich ___ http://www.mccmedia.com/mailman/listinfo/brin-l
Re: Morality
JDG said: Given the existence of universal truth, I don't see how the number "n" of people who fail to recognize and accept that universal truth is at all relevant. After all, that universal truth is, by definition, universally true. Yes, indeed. But Dan was specifically talking about transcendental truths. If we have no way to determine those truths, and thus no way to act on them, then they're of no use to us whatsoever. So far, nobody has presented me with an acceptable criterion for a moral assertion to be true, let alone for something like "God exists" to be true.

Damon said: IRC, thinking back to my college classes, the downfall of both the Old and Middle kingdoms came during times of political unrest... It's quite hard at this distance to determine the causes of the end of the Old and Middle kingdoms when we can only barely discern even the symptoms. What is clear is that the end of both was a gradual process, with a weakened central authority coexisting with strengthening regional administrations for many decades, rather than a dramatic downfall. (There was a tendency towards regionalism throughout Egyptian history, especially when weakened pharaohs allowed administrative or religious posts in the nomes to become hereditary. A strong king was largely one who could impose his will in appointing people to these posts.) In the case of the First Intermediate Period, it's been suggested that a period of reduced inundations of the Nile in turn reduced the agricultural surplus on which the Old Kingdom regime depended, and local people looked to local powers to provide for them during a time of famine. The Second Intermediate Period saw the Nile delta dominated by the Hyksos kings, who invaded Egypt from Palestine. The Middle Kingdom had seen a gradual infiltration of Egypt by "asiatics" (including people from the Eastern Desert) and perhaps the support of these people for the Hyksos invaders proved the deciding factor. (As I've already said, the increased power of the priesthood of Amun was a factor in the end of the New Kingdom, as was the erosion of the Egyptian empire in Palestine and Syria under pressure from the Hittites.)

William said: Agnosticism : ~Believe {God(s) exist} is true Atheism : Believe {God(s) exist} is ~true I think you're wrong on the former.

I think JohnR's argument is that belief breathes the "fire" into the words and unless you believe you don't experience that fire and so don't truly understand.

Re: The Morality of Killing Babies
JohnR said: So what? In the USA people need to eat less anyway. And globally, there needs to be a reduction in population that could most easily be effected by widespread starvation.

That is, I would if I did not believe that every human being on this earth is a child of the same Heavenly Father and hence truly brothers and sisters.

Re: The Morality of Killing Babies
Dan said: Actually, it is possible, with a simple assumption, to do more than that. Again, I fully admit that there is no proof, but I think that...if the transcendental is partially and imperfectly discerned by humans, then one can reach some general conclusions about our best bets at approaching the truth when it comes to ethics. I'll stop here to see if you think that is a presupposition that is worth exploring further. I'm always interested to hear what you have to say on such things, even though I'm fairly sceptical about the possibility of discerning anything transcendental.

Re: The Morality of Killing Babies
Andrew said: Again, Jews believe there are universal standards for good and for righteousness (and that the most certainly don't need to be a Jew to be righteous) - and further, the Bible states that the Law of the Land is the Law. So is that an argument from the authority of the Bible, an argument from the authority of the people who wrote Bible, an argument from the authority of the traditions of the ancient Jewish people or something else? No. You're commiting the basic theological falicy (again, in Jewish terms) of thinking of G-d as a Human. To eff the ineffible. Which is understandable (especially since Christians HAVE adopted a Human aspect to their G-d) but from our POV the question is meaningless in context. Well, that sounds awfully like you're saying that these things are true because an all-powerful and ineffable God said so but that we shouldn't really look too closely into such matters. Which, to me (although presumably not to others), sounds awfully like an argument from the authority of one's imaginary friend. Rich ___ http://www.mccmedia.com/mailman/listinfo/brin-l

DanM said: > I think the most critical question involved is the understanding of the > transcendental: Truths that are true, whether or not they are believed > by humans, or even whether they are perceived by humans; Reality that > exists apart from our perception. But that seems like an especially useless position. If we're discussing which things are good and which are evil then believing that there are transcendental truths doesn't help at all if different people have different positions on what those truths actually are. So far as I can tell you're reduced either to an argument from authority (whether that of a priesthood, a holy book, one or more historical figures, or the "general sentiments of society") or an argument from what makes you feel all warm and fuzzy inside. At best, I suppose, you can argue that some of those priesthoods, holy books, historical figures or warm and fuzzy feelings are divinely inspired rather than ultimately reducing just to opinion, but once again we can argue endlessly about exactly which of those things are touched by the ineffable mystery of the transcendental.
