The unchristian cross III

The Two Babylons, Alexander Hislop, Chapter V, Section VI, The Sign of the Cross


There is yet one more symbol of the Romish worship to be noticed, and that is the sign of the cross. In the Papal system as is well known, the sign of the cross and the image of the cross are all in all. No prayer can be said, no worship engaged in, no step almost can be taken, without the frequent use of the sign of the cross. The cross is looked upon as the grand charm, as the great refuge in every season of danger, in every hour of temptation as the infallible preservative from all the powers of darkness. The cross is adored with all the homage due only to the Most High; and for any one to call it, in the hearing of a genuine Romanist, by the Scriptural term, "the accursed tree," is a mortal offence. To say that such superstitious feeling for the sign of the cross, such worship as Rome pays to a wooden or a metal cross, ever grew out of the saying of Paul, "God forbid that I should glory, save in the cross of our Lord Jesus Christ"--that is, in the doctrine of Christ crucified--is a mere absurdity, a shallow subterfuge and pretence. The magic virtues attributed to the so-called sign of the cross, the worship bestowed on it, never came from such a source. The same sign of the cross that Rome now worships was used in the Babylonian Mysteries, was applied by Paganism to the same magic purposes, was honoured with the same honours. That which is now called the Christian cross was originally no Christian emblem at all, but was the mystic Tau of the Chaldeans and Egyptians--the true original form of the letter T--the initial of the name of Tammuz--which, in Hebrew, radically the same as ancient Chaldee, was found on coins. That mystic Tau was marked in baptism on the foreheads of those initiated in the Mysteries, * and was used in every variety of way as a most sacred symbol.

* TERTULLIAN, De Proescript. Hoeret. The language of Tertullian implies that those who were initiated by baptism in the Mysteries were marked on the forehead in the same way, as his Christian countrymen in Africa, who had begun by this time to be marked in baptism with the sign of the cross.

To identify Tammuz with the sun it was joined sometimes to the circle of the sun; sometimes it was inserted in the circle. Whether the Maltese cross, which the Romish bishops append to their names as a symbol of their episcopal dignity, is the letter T, may be doubtful; but there seems no reason to doubt that that Maltese cross is an express symbol of the sun; for Layard found it as a sacred symbol in Nineveh in such a connection as led him to identify it with the sun. The mystic Tau, as the symbol of the great divinity, was called "the sign of life"; it was used as an amulet over the heart; it was marked on the official garments of the priests, as on the official garments of the priests of Rome; it was borne by kings in their hand, as a token of their dignity or divinely-conferred authority. The Vestal virgins of Pagan Rome wore it suspended from their necklaces, as the nuns do now. The Egyptians did the same, and many of the barbarous nations with whom they had intercourse, as the Egyptian monuments bear witness. In reference to the adorning of some of these tribes, Wilkinson thus writes: "The girdle was sometimes highly ornamented; men as well as women wore earrings; and they frequently had a small cross suspended to a necklace, or to the collar of their dress. The adoption of this last was not peculiar to them; it was also appended to, or figured upon, the robes of the Rot-n-no; and traces of it may be seen in the fancy ornaments of the Rebo, showing that it was already in use as early as the fifteenth century before the Christian era." There is hardly a Pagan tribe where the cross has not been found. The cross was worshipped by the Pagan Celts long before the incarnation and death of Christ. "It is a fact," says Maurice, "not less remarkable than well-attested, that the Druids in their groves were accustomed to select the most stately and beautiful tree as an emblem of the Deity they adored, and having cut the side branches, they affixed two of the largest of them to the highest part of the trunk, in such a manner that those branches extended on each side like the arms of a man, and, together with the body, presented the appearance of a HUGE CROSS, and on the bark, in several places, was also inscribed the letter Thau." It was worshipped in Mexico for ages before the Roman Catholic missionaries set foot there, large stone crosses being erected, probably to the "god of rain." The cross thus widely worshipped, or regarded as a sacred emblem, was the unequivocal symbol of Bacchus, the Babylonian Messiah, for he was represented with a head-band covered with crosses. This symbol of the Babylonian god is reverenced at this day in all the wide wastes of Tartary, where Buddhism prevails, and the way in which it is represented among them forms a striking commentary on the language applied by Rome to the Cross. "The cross," says Colonel Wilford, in the Asiatic Researches, "though not an object of worship among the Baud'has or Buddhists, is a favourite emblem and device among them. It is exactly the cross of the Manicheans, with leaves and flowers springing from it. This cross, putting forth leaves and flowers (and fruit also, as I am told), is called the divine tree, the tree of the gods, the tree of life and knowledge, and productive of whatever is good and desirable, and is placed in the terrestrial paradise." Compare this with the language of Rome applied to the cross, and it will be seen how exact is the coincidence. In the Office of the Cross, it is called the "Tree of life," and the worshippers are taught thus to address it: "Hail, O Cross, triumphal wood, true salvation of the world, among trees there is none like thee in leaf, flower, and bud...O Cross, our only hope, increase righteousness to the godly and pardon the offences of the guilty." *

* The above was actually versified by the Romanisers in the Church of England, and published along with much besides from the same source, some years ago, in a volume entitled Devotions on the Passion. The London Record, of April, 1842, gave the following as a specimen of the "Devotions" provided by these "wolves in sheep's clothing" for members of the Church of England:--

"O faithful cross, thou peerless tree,
No forest yields the like of thee,
Leaf, flower, and bud;
Sweet is the wood, and sweet the weight,
And sweet the nails that penetrate
Thee, thou sweet wood."

Can any one, reading the gospel narrative of the crucifixion, possibly believe that that narrative of itself could ever germinate into such extravagance of "leaf, flower, and bud," as thus appears in this Roman Office? But when it is considered that the Buddhist, like the Babylonian cross, was the recognised emblem of Tammuz, who was known as the mistletoe branch, or "All-heal," then it is easy to see how the sacred Initial should be represented as covered with leaves, and how Rome, in adopting it, should call it the "Medicine which preserves the healthful, heals the sick, and does what mere human power alone could never do."

Now, this Pagan symbol seems first to have crept into the Christian Church in Egypt, and generally into Africa. A statement of Tertullian, about the middle of the third century, shows how much, by that time, the Church of Carthage was infected with the old leaven. Egypt especially, which was never thoroughly evangelised, appears to have taken the lead in bringing in this Pagan symbol. The first form of that which is called the Christian Cross, found on Christian monuments there, is the unequivocal Pagan Tau, or Egyptian "Sign of life." Let the reader peruse the following statement of Sir G. Wilkinson: "A still more curious fact may be mentioned respecting this hieroglyphical character [the Tau], that the early Christians of Egypt adopted it in lieu of the cross, which was afterwards substituted for it, prefixing it to inscriptions in the same manner as the cross in later times. For, though Dr. Young had some scruples in believing the statement of Sir A. Edmonstone, that it holds that position in the sepulchres of the great Oasis, I can attest that such is the case, and that numerous inscriptions, headed by the Tau, are preserved to the present day on early Christian monuments." The drift of this statement is evidently this, that in Egypt the earliest form of that which has since been called the cross, was no other than the "Crux Ansata," or "Sign of life," borne by Osiris and all the Egyptian gods; that the ansa or "handle" was afterwards dispensed with, and that it became the simple Tau, or ordinary cross, as it appears at this day, and that the design of its first employment on the sepulchres, therefore, could have no reference to the crucifixion of the Nazarene, but was simply the result of the attachment to old and long-cherished Pagan symbols, which is always strong in those who, with the adoption of the Christian name and profession, are still, to a large extent, Pagan in heart and feeling. This, and this only, is the origin of the worship of the "cross."

This, no doubt, will appear all very strange and very incredible to those who have read Church history, as most have done to a large extent, even amongst Protestants, through Romish spectacles; and especially to those who call to mind the famous story told of the miraculous appearance of the cross to Constantine on the day before the decisive victory at the Milvian bridge, that decided the fortunes of avowed Paganism and nominal Christianity. That story, as commonly told, if true, would certainly give a Divine sanction to the reverence for the cross. But that story, when sifted to the bottom, according to the common version of it, will be found to be based on a delusion--a delusion, however, into which so good a man as Milner has allowed himself to fall. Milner's account is as follows: "Constantine, marching from France into Italy against Maxentius, in an expedition which was likely either to exalt or to ruin him, was oppressed with anxiety. Some god he thought needful to protect him; the God of the Christians he was most inclined to respect, but he wanted some satisfactory proof of His real existence and power, and he neither understood the means of acquiring this, nor could he be content with the atheistic indifference in which so many generals and heroes since his time have acquiesced. He prayed, he implored with such vehemence and importunity, and God left him not unanswered. While he was marching with his forces in the afternoon, the trophy of the cross appeared very luminous in the heavens, brighter than the sun, with this inscription, 'Conquer by this.' He and his soldiers were astonished at the sight; but he continued pondering on the event till night. And Christ appeared to him when asleep with the same sign of the cross, and directed him to make use of the symbol as his military ensign." Such is the statement of Milner. Now, in regard to the "trophy of the cross," a few words will suffice to show that it is utterly unfounded. I do not think it necessary to dispute the fact of some miraculous sign having been given. There may, or there may not, have been on this occasion a "dignus vindice nodus," a crisis worthy of a Divine interposition. Whether, however, there was anything out of the ordinary course, I do not inquire. But this I say, on the supposition that Constantine in this matter acted in good faith, and that there actually was a miraculous appearance in the heavens, that it as not the sign of the cross that was seen, but quite a different thing, the name of Christ. That this was the case, we have at once the testimony of Lactantius, who was the tutor of Constantine's son Crispus--the earliest author who gives any account of the matter, and the indisputable evidence of the standards of Constantine themselves, as handed down to us on medals struck at the time. The testimony of Lactantius is most decisive: "Constantine was warned in a dream to make the celestial sign of God upon his solders' shields, and so to join battle. He did as he was bid, and with the transverse letter X circumflecting the head of it, he marks Christ on their shields. Equipped with this sign, his army takes the sword." Now, the letter X was just the initial of the name of Christ, being equivalent in Greek to CH. If, therefore, Constantine did as he was bid, when he made "the celestial sign of God" in the form of "the letter X," it was that "letter X," as the symbol of "Christ" and not the sign of the cross, which he saw in the heavens. When the Labarum, or far-famed standard of Constantine itself, properly so called, was made, we have the evidence of Ambrose, the well-known Bishop of Milan, that that standard was formed on the very principle contained in the statement of Lactantius--viz., simply to display the Redeemer's name. He calls it "Labarum, hoc est Christi sacratum nomine signum."--"The Labarum, that is, the ensign consecrated by the NAME of Christ." *

* Epistle of Ambrose to the Emperor Theodosius about the proposal to restore the Pagan altar of Victory in the Roman Senate. The subject of the Labarum has been much confused through ignorance of the meaning of the word. Bryant assumes (and I was myself formerly led away by the assumption) that it was applied to the standard bearing the crescent and the cross, but he produces no evidence for the assumption; and I am now satisfied that none can be produced. The name Labarum, which is generally believed to have come from the East, treated as an Oriental word, gives forth its meaning at once. It evidently comes from Lab, "to vibrate," or "move to and fro," and ar "to be active." Interpreted thus, Labarum signifies simply a banner or flag, "waving to and fro" in the wind, and this entirely agrees with the language of Ambrose "an ensign consecrated by the name of Christ," which implies a banner.

There is not the slightest allusion to any cross--to anything but the simple name of Christ. While we have these testimonies of Lactantius and Ambrose, when we come to examine the standard of Constantine, we find the accounts of both authors fully borne out; we find that that standard, bearing on it these very words, "Hoc signo victor eris," "In this sign thou shalt be a conqueror," said to have been addressed from heaven to the emperor, has nothing at all in the shape of a cross, but "the letter X." In the Roman Catacombs, on a Christian monument to "Sinphonia and her sons," there is a distinct allusion to the story of the vision; but that allusion also shows that the X, and not the cross, was regarded as the "heavenly sign." The words at the head of the inscription are these: "In Hoc Vinces [In this thou shalt overcome] X." Nothing whatever but the X is here given as the "Victorious Sign." There are some examples, no doubt, of Constantine's standard, in which there is a cross-bar, from which the flag is suspended, that contains that "letter X"; and Eusebius, who wrote when superstition and apostacy were working, tries hard to make it appear that that cross-bar was the essential element in the ensign of Constantine. But this is obviously a mistake; that cross-bar was nothing new, nothing peculiar to Constantine's standard. Tertullian shows that that cross-bar was found long before on the vexillum, the Roman Pagan standard, that carried a flag; and it was used simply for the purpose of displaying that flag. If, therefore, that cross-bar was the "celestial sign," it needed no voice from heaven to direct Constantine to make it; nor would the making or displaying of it have excited any particular attention on the part of those who saw it. We find no evidence at all that the famous legend, "In this overcome," has any reference to this cross-bar; but we find evidence the most decisive that that legend does refer to the X. Now, that that X was not intended as the sign of the cross, but as the initial of Christ's name, is manifest from this, that the Greek P, equivalent to our R, is inserted in the middle of it, making by their union CHR. The standard of Constantine, then, was just the name of Christ. Whether the device came from earth or from heaven--whether it was suggested by human wisdom or Divine, supposing that Constantine was sincere in his Christian profession, nothing more was implied in it than a literal embodiment of the sentiment of the Psalmist, "In the name of the Lord will we display our banners." To display that name on the standards of Imperial Rome was a thing absolutely new; and the sight of that name, there can be little doubt, nerved the Christian soldiers in Constantine's army with more than usual fire to fight and conquer at the Milvian bridge.

In the above remarks I have gone on the supposition that Constantine acted in good faith as a Christian. His good faith, however, has been questioned; and I am not without my suspicions that the X may have been intended to have one meaning to the Christians and another to the Pagans. It is certain that the X was the symbol of the god Ham in Egypt, and as such was exhibited on the breast of his image. Whichever view be taken, however, of Constantine's sincerity, the supposed Divine warrant for reverencing the sign of the cross entirely falls to the ground. In regard to the X, there is no doubt that, by the Christians who knew nothing of secret plots or devices, it was generally taken, as Lactantius declares, as equivalent to the name of "Christ." In this view, therefore, it had no very great attractions for the Pagans, who, even in worshipping Horus, had always been accustomed to make use of the mystic tau or cross, as the "sign of life," or the magical charm that secured all that was good, and warded off everything that was evil. When, therefore, multitudes of the Pagans, on the conversion of Constantine, flocked into the Church, like the semi-Pagans of Egypt, they brought along with them their predilection for the old symbol. The consequence was, that in no great length of time, as apostacy proceeded, the X which in itself was not an unnatural symbol of Christ, the true Messiah, and which had once been regarded as such, was allowed to go entirely into disuse, and the Tau, the sign of the cross, the indisputable sign of Tammuz, the false Messiah, was everywhere substituted in its stead. Thus, by the "sign of the cross," Christ has been crucified anew by those who profess to be His disciples. Now, if these things be matter of historic fact, who can wonder that, in the Romish Church, "the sign of the cross" has always and everywhere been seen to be such an instrument of rank superstition and delusion?

There is more, much more, in the rites and ceremonies of Rome that might be brought to elucidate our subject. But the above may suffice. *

* If the above remarks be well founded, surely it cannot be right that this sign of the cross, or emblem of Tammuz, should be used in Christian baptism. At the period of the Revolution, a Royal Commission, appointed to inquire into the Rites and Ceremonies of the Church of England, numbering among its members eight or ten bishops, strongly recommended that the use of the cross, as tending to superstition, should be laid aside. If such a recommendation was given then, and that by such authority as members of the Church of England must respect, how much ought that recommendation to be enforced by the new light which Providence has cast on the subject!

As many have suspected, there is much more to the true, authentic history of the Christian religion than what we had originally been told. Some claims regarding the Church's history are accurate, some are not. The most extreme claims against the religion come from the atheist camp and often remain unproved. But this book is completely different. It comes from a devout Christian, Henry Dana Ward, a believer in Christ who backs himself up with scholarly research and facts. Why, then, was this book written if it goes against traditional beliefs and acceptance? It is because the traditional beliefs surrounding the cross and its worship are wrong! It took time for us to eventually accept the cross in its current form and to worship it and, according to Ward, this was a pagan symbol that should never have been adopted. Idols were not to be worshipped by the earliest of Christians, and the cross was no exception to this rule. Not worshipping the cross is consistent with early Christianity and is not heretical. Its lack of worship is part of Christianity's foundational beliefs and its exclusion should be part of the religion's current structure, according to Ward. Revering the cross is based on lies, deception, and ignorance. Ward shows how the lies began, who spread them, and how and why they did it.

You may be surprised to learn that many traditions of Roman Catholicism in fact dont come from Christs teachings but from an ancient Babylonian Mystery religion that was centered on Nimrod, his wife Semiramis, and a child Tammuz. This book shows how this ancient religion transformed itself as it incorporated Christ into its teachings. You may be surprised that certain practices like confessions, and crossing ones self, and even the position of the Pope come from traditions of this mystery cult. Originally a pamphlet published in 1853, The Two Babylons is Hislop's most famous work. In this book he argues that the Roman Catholic Church is nothing more than pagan cult, with roots in Babylonian mystery cults, which have a bank of secret knowledge only available to those who have been formally accepted into the cult. Roman Catholics, Hislop argues, are descendants from early Christians who adopted the Roman religion descended from the worship of Semiramis, the wife of the founder of Babylon. By discrediting the true Christianity of Catholics, Hislop hoped to bolster the legitimacy of the Protestant and Scottish Reformations. Students of theology and those interested in the complex history of Christianity will find Hislop's arguments provocative enough that they may be moved to further research of their own. Scottish minister ALEXANDER HISLOP (1807-1865) became an ordained clergymen in the Free Church of Scotland in 1844. As a Presbyterian minister, Hislop was famously critical of the Roman Catholic Church. He wrote a number of books including Christ's Crown and Covenant (1860) and The Moral Identity of Babylon and Rome (1855). http://philologos.org/__eb-ttb/

The history of the symbol of the cross has had an attraction for the author ever since, as an enquiring youth, he found himself unable to obtain satisfactory answers to four questions concerning the same which presented themselves to his mind. The first of those questions was why John the Baptist, who was beheaded before Jesus was executed, and so far as we are told never had anything to do with a cross, is represented in our religious pictures as holding a cross. The second question was whether this curious but perhaps in itself easily explained practice had in its inception any connection with the non-Mosaic initiatory rite of baptism; which Jesus accepted as a matter of course at the hands of his cousin John, and in which the sign of the cross has for ages been the all-important feature. And it was the wonder whether there was or was not some association between the facts that the New Testament writers give no explanation whatever of the origin of baptism as an initiatory rite, that this non-Mosaic initiatory rite was in use among Sun-God worshippers long before our era, and that the Fathers admitted that the followers of the Persian conception of the Sun-God marked their initiates upon the forehead like the followers of the Christ, which finally induced the author to start a systematic enquiry into the history of the cross as a symbol.

The third question was why, despite the fact that the instrument of execution to which Jesus was affixed can have had but one shape, almost any kind of cross is accepted as a symbol of our faith. The last of the four questions was why many varieties of the cross of four equal arms, which certainly was not a representation of an instrument of execution, were accepted by Christians as symbols of the Christ before any cross which could possibly have been a representation of an instrument of execution was given a place among the symbols of Christianity; while even nowadays one variety of the cross of four equal arms is the favourite symbol of the Greek Church, and both it and the other varieties enter into the ornamentation of our sacred properties and dispute the supremacy with the cross which has one of its arms longer than the other three. Pursuing these matters for himself, the author eventually found that even before our era the cross was venerated by many as the symbol of Life; though our works of reference seldom mention this fact, and never do it justice. He moreover discovered that no one has ever written a complete history of the symbol, showing the possibility that the stauros or post to which Jesus was affixed was not cross-shaped, and the certainty that, in any case, what eventually became the symbol of our faith owed some of its prestige as a Christian symbol of Victory and Life to the position it occupied in pre-Christian days. The author has therefore, in the hope of drawing attention to the subject, incorporated the results of his researches in the present essay.

This study investigates the philological aspects of how ancient Greek, Latin and Hebrew/Aramaic texts, including the New Testament, depict the practice of punishment by crucifixion. A survey of the ancient text material shows that there has been a too narrow view of the “crucifixion” terminology. The various terms are not simply used in the sense of “crucify” and “cross,” if by “crucifixion” one means the punishment that Jesus was subjected to according to the main Christian traditions. The terminology is used much more diversely. Almost none of it can be elucidated beyond verbs referring vaguely to some form(s) of suspension, and nouns referring to tools used in such suspension. As a result, most of the crucifixion accounts that scholars cite in the ancient literature have to be rejected, leaving only a few. The New Testament is not spared from this terminological ambiguity. The accounts of the death of Jesus are strikingly sparse. Their chief contribution is usage of the unclear terminology in question. Over-interpretation, and probably even pure imagination, have afflicted nearly every wordbook and dictionary that deals with the terms related to crucifixion as well as scholarly depictions of what happened on Calvary. The immense knowledge of the punishment of crucifixion in general, and the execution of Jesus in particular, cannot be supported by the studied texts. http://www.exegetics.org/

The unchristian cross IV

Did Jesus Die on a Cross?

The Bible’s answer

Many view the cross as the most common symbol of Christianity. However, the Bible does not describe the instrument of Jesus’ death, so no one can know its shape with absolute certainty. Still, the Bible provides evidence that Jesus died, not on a cross, but on an upright stake.

The Bible generally uses the Greek word stau·ros′ when referring to the instrument of Jesus’ execution. (Matthew 27:40; John 19:17) Although translations often render this word “cross,” many scholars agree that its basic meaning is actually “upright stake.” * According to A Critical Lexicon and Concordance to the English and Greek New Testament, stau·ros′ “never means two pieces of wood joining each other at any angle.”

The Bible also uses the Greek word xy′lon as a synonym for stau·ros′. (Acts 5:30; 1 Peter 2:24) This word means “wood,” “timber,” “stake,” or “tree.” * The Companion Bible thus concludes: “There is nothing in the Greek of the N[ew] T[estament] even to imply two pieces of timber.”

Is using the cross in worship acceptable to God?

Regardless of the shape of the instrument on which Jesus died, the following facts and Bible verses indicate that we should not use the cross in worship.

God rejects worship that uses images or symbols, including the cross. God commanded the Israelites not to use “the form of any symbol” in their worship, and Christians are likewise told to “flee from idolatry.”—Deuteronomy 4:15-19; 1 Corinthians 10:14.
First-century Christians did not use the cross in worship.
 *  The teachings and example of the apostles set a pattern that all Christians should adhere to.—2 Thessalonians 2:15.
Use of the cross in worship has a pagan origin. * Hundreds of years after the death of Jesus, when the churches had deviated from his teachings, new church members “were permitted largely to retain their pagan signs and symbols,” including the cross. (The Expanded Vine’s Expository Dictionary of New Testament Words) However, the Bible does not condone adopting pagan symbols to help make new converts.—2 Corinthians 6:17.

Why Human Reason Didn’t “Evolve”

 David Klinghoffer | @d_klinghoffer

 The indispensable neuroscientist Michael Egnor, writing at Mind Matters, applies some needed intellectual rigor in disciplining atheist philosopher Justin E.H. Smith. In a new book, Irrationality: A History of the Dark Side of Reason, Professor Smith “argues that reason is inferior to the non-rational behavior of animals.” Egnor: “Think of the irony: a professor of philosophy, who is paid only to reason, uses reason to argue against reason. Welcome to the bowels of atheist metaphysics.”

According to Smith, writing at Aeon, “Philosophers and cognitive scientists today generally comprehend the domain of reason as a certain power of making inferences, confined to the thoughts and actions of human beings alone.” Well, not exactly. Reason, as Dr. Egnor reminds him, is nothing  more or less than the ability to think abstractly, as opposed to thinking about physical objects. 

A Clever Dog

An example of the latter would be thinking about how to get out of your doggie play pen. Our family is currently testing out a puppy (long story) who has surprised me repeatedly when I wasn’t looking by somehow escaping from a closed play pen. It took me a while to figure out how he was doing it, since the pen is about twice his height. Even then I had to catch him in the act. Clever dog! But he wasn’t engaging in the activity of reasoning by, let’s say, contemplating the idea of freedom. Egnor:

Only man thinks abstractly; that is the ability to reason. No animal, no matter how clever, can think abstractly or reason. Animals can be very clever but their cleverness is always about concrete things — about the bone they are playing with, or about the stranger they are barking at. They don’t think about “play” or “threat” as abstract concepts.

Tough to Explain

Smith says, “Like echolocation in bats or photosynthesis in plants, reason is an evolved power.” But if reason is unique to humans, and exists nowhere else in life, did it indeed “evolve” from lower animals? That’s a tough question. In fact, Egnor explains why it didn’t, at least not by any purely material mechanism like the Darwinian one:

Reason is a power characteristic of man, to be sure, but it is not “an evolved power.” It didn’t “evolve.” The ability to reason didn’t evolve because it’s not a material power of the mind. Reason is an immaterial power of the mind — it is abstracted from particular things, and cannot logically be produced by a material thing.

A purely material process can’t “evolve” a spiritual power. Egnor is, as I said, indispensable. Read the read as Mind Matters.

Physicist tells people to stop saying they have free will
January 13, 2016 Posted by vjtorley under Intelligent Design

Over at her BackReAction blog, Dr. Sabine Hossenfelder, a theoretical physicist based at the Frankfurt Institute for Advanced Studies in Frankfurt, Germany, has written an article titled, Free will is dead, let’s bury it. However, her arguments against free will are both scientifically unsound and philosophically dated. She writes:

There are only two types of fundamental laws that appear in contemporary theories. One type is deterministic, which means that the past entirely predicts the future. There is no free will in such a fundamental law because there is no freedom. The other type of law we know appears in quantum mechanics and has an indeterministic component which is random. This randomness cannot be influenced by anything, and in particular it cannot be influenced by you, whatever you think “you” are. There is no free will in such a fundamental law because there is no “will” – there is just some randomness sprinkled over the determinism.

In neither case do you have free will in any meaningful way.

These are the only two options, and all other elaborations on the matter are just verbose distractions. It doesn’t matter if you start talking about chaos (which is deterministic), top-down causation (which doesn’t exist), or insist that we don’t know how consciousness really works (true but irrelevant). It doesn’t change a thing about this very basic observation: there isn’t any known law of nature that lets you meaningfully speak of “free will”.

If you don’t want to believe that, I challenge you to write down any equation for any system that allows for something one could reasonably call free will…

The only known example for a law that is neither deterministic nor random comes from myself. But it’s a baroque construct meant as proof in principle, not a realistic model that I would know how to combine with the four fundamental interactions.

First of all, let’s get the bad science out of the way. Dr. Hossenfelder insists that top-down causation “doesn’t exist.” She should try telling that to George Ellis, an eminent cosmologist at the University of Cape Town, whose scientific work is described by Adam Frank in an article titled, How Does The World Work: Top-Down or Bottom-Up?, over at NPR’s 13.7: Cosmos And Culture blog:

In an essay for the physics website FQXi, Ellis argues for top-down causation. If he’s right, then much of our thinking about what matters would have to be revised.

To get an handle on how top-down causation works, Ellis focuses on what’s in front of all us so much of the time: the computer. Computers are structured systems. They are built as a hierarchy of layers, extending from the wires in the transistors all the way up to the fully assembled machine, gleaming metal case and all.

Because of this layering, what happens at the uppermost levels — like you hitting the escape key — flows downward. This action determines the behavior of the lowest levels — like the flow of electrons through the wires — in ways that simply could not be predicted by just knowing the laws of electrons…

But the hardware, of course, is just one piece of the puzzle. This is where things get interesting. As Ellis explains:

Hardware is only causally effective because of the software which animates it: by itself hardware can do nothing. Both hardware and software are hierarchically structured with the higher level logic driving the lower level events.
In other words, it’s software at the top level of structure that determines how the electrons at the bottom level flow. Hitting escape while running Word moves the electrons in the wires in different ways than hitting escape does when running Photoshop. This is causation flowing from top to bottom…

Ellis is arguing for a kind of emergentism whereby new entities and new rules emerge with new levels of structure in the universe (an argument also made by Stuart Kaufmann here at 13.7). But Ellis is going further. He is arguing that the top is always exerting an influence on the bottom.

Ellis concludes his FQXI esssay, Recognising Top-Down Causation, with a bold hypothesis, and he puts forward some concrete research proposals which he believes will fundamentally transform the nature of science (bold emphases mine – VJT):

Hypothesis: bottom up emergence by itself is strictly limited in terms of the complexity it can give rise to. Emergence of genuine complexity is characterised by a reversal of information flow from bottom up to top down [27].

The degree of complexity that can arise by bottom-up causation alone is strictly limited. Sand piles, the game of life, bird flocks, or any dynamics governed by a local rule [28] do not compare in complexity with a single cell or an animal body. The same is true in physics: spontaneously broken symmetry is powerful [16], but not as powerful as symmetry breaking that is guided top-down to create ordered structures (such as brains and computers). Some kind of coordination of effects is needed for such complexity to emerge.

The assumption that causation is bottom up only is wrong in biology, in computers, and even in many cases in physics, for example state vector preparation, where top-down constraints allow non-unitary behaviour at the lower levels. It may well play a key role in the quantum measurement problem (the dual of state vector preparation) [5]. One can bear in mind here that wherever equivalence classes of entities play a key role, such as in Crutchfield’s computational mechanics [29], this is an indication that top-down causation is at play.

There are some great discussions of the nature of emergent phenomena in physics [17,1,12,30], but
none of them specifically mention the issue of top down causation. This paper proposes that
recognising this feature will make it easier to comprehend the physical effects underlying emergence of genuine complexity, and may lead to useful new developments, particularly to do with the foundational nature of quantum theory. It is a key missing element in current physics.

Having disposed of Dr. Hossenfelder’s claim that top-down causation doesn’t exist, I’d now like to examine her philosophical argument. Briefly, the argument she puts forward is a variant of what Bob Doyle describes as The Standard Argument against Free Will, at his Information Philosopher Website:

First, if determinism is the case, the will is not free. We call this the Determinism Objection.

Second, if indeterminism and real chance exist, our will would not be in our control, we could not be responsible for random actions. We call this the Randomness Objection.

Together, these objections can be combined in the Responsibility Objection, namely that no Free Will model has yet provided us an intelligible account of the agent control needed for moral responsibility.

Both parts are logically and practically flawed, partly from abuse of language that led some 20th-century philosophers to call free will a “pseudo-problem,” and partly from claims to knowledge that are based on faulty evidence.

So why does Doyle think the Standard Argument Against Free Will is flawed? First, Doyle argues that determinism is empirically false: quantum physics introduces a significant degree of indeterminism into the world, even at the macro level. Second, Doyle maintains that chance would undercut freedom only if it were a cause of our actions, but in his preferred two-stage Cogito model, it’s not: chance serves to dish up a random array of possibilities, and then something called “MacroMind” takes over, and makes a decision, based on the individual’s past history of preferences. However, I don’t propose to discuss Doyle’s Cogito model further here, because Doyle himself rejects the strong libertarian view (which I support), that “a decision is directly free only if, until it is made, the agent is able to do other than make that decision, where this is taken to require that, until the action occurs, there is a chance that it will not occur.” Indeed, Doyle explicitly acknowledges that in his Cogito model, during the split-second before a choice is made, “the decision could be reliably (though not perfectly) predicted by a super-psychiatrist who knew everything about the agent and was aware of all the alternative possibilities.” To my mind, that’s a Pickwickian account of freedom.

For her part, Dr. Hossenfelder vehemently disagrees with Doyle’s contention that quantum physics entails indeterminism: she points out that superdeterminism (the hypothesis that the quantum measurements that experimenters choose to make are themselves predetermined by the laws of physics) is an equally consistent possibility – and, I might add, one that was acknowledged by John Bell himself: see The Ghost in the Atom: A Discussion of the Mysteries of Quantum Physics, by Paul C. W. Davies and Julian R. Brown, 1986/1993, pp. 45-47). For my part, I think physicist Anton Zeilinger identified the flaw in superdeterminism when he perceptively commented:

[W]e always implicitly assume the freedom of the experimentalist… This fundamental assumption is essential to doing science. If this were not true, then, I suggest, it would make no sense at all to ask nature questions in an experiment, since then nature could determine what our questions are, and that could guide our questions such that we arrive at a false picture of nature. (Dance of the Photons, Farrar, Straus and Giroux, New York, 2010, p. 266.)

Additionally, I should point out that even on a classical, Newtonian worldview, determinism does not follow. Newtonian mechanics is popularly believed to imply determinism, but this belief was exploded over two decades ago by John Earman (A Primer on Determinism, 1986, Dordrecht: Reidel, chapter III). In 2006, Dr. John Norton put forward a simple illustration which is designed to show that violations of determinism can arise very easily in a system governed by Newtonian physics (The Dome: An Unexpectedly Simple Failure of Determinism. 2006 Philosophy of Science Association 20th Biennial Meeting (Vancouver), PSA 2006 Symposia.) In Norton’s example, a mass sits on a dome in a gravitational field. After remaining unchanged for an arbitrary time, it spontaneously moves in an arbitrary direction. The mass’s indeterministic motion is clearly compatible with Newtonian mechanics. Norton describes his example as an exceptional case of indeterminism arising in a Newtonian system with a finite number of degrees of freedom. (On the other hand, indeterminism is generic for Newtonian systems with infinitely many degrees of freedom.)

Sometimes the Principle of Least Action is said to imply determinism. But since the wording of the principle shows that it only applies to systems in which total mechanical energy (kinetic energy plus potential energy) is conserved, and as it deals with the trajectory of particles in motion, I fail to see how it would apply to collisions between particles, in which mechanical energy is not necessarily conserved. At best, it seems that the universe is fully deterministic only if particles behave like perfectly elastic billiard balls – which is only true in an artificially simplified version of the cosmos.

Finally, I should like to add that in my own top-down model of free will (as with Doyle’s), chance does not figure as a cause of our choices. In my model, it serves as the matrix upon which non-random, but undetermined, free choices are imposed, via a form of top-down causation. Here’s how I described it in a 2012 post titled, Is free will dead?:

…[I]t is easy to show that a non-deterministic system may be subject to specific constraints, while still remaining random. These constraints may be imposed externally, or alternatively, they may be imposed from above, as in top-down causation. To see how this might work, suppose that my brain performs the high-level act of making a choice, and that this act imposes a constraint on the quantum micro-states of tiny particles in my brain. This doesn’t violate quantum randomness, because a selection can be non-random at the macro level, but random at the micro level. The following two rows of digits will serve to illustrate my point.

1 0 0 0 1 1 1 1 0 0 0 1 0 1 0 0 1 1
0 0 1 0 0 0 0 1 1 0 1 1 0 1 1 1 0 1

The above two rows of digits were created by a random number generator. The digits in some of these columns add up to 0; some add up to 1; and some add up to 2.

Now suppose that I impose the non-random macro requirement: keep the columns whose sum equals 1, and discard the rest. I now have:

1 0 1 1 1 0 0 0 0 0 1
0 1 0 0 0 1 1 0 1 1 0

Each row is still random (at the micro level), but I have now imposed a non-random macro-level constraint on the system as a whole (at the macro level). That, I would suggest, what happens when I make a choice.

Top-down causation and free will

What I am proposing, in brief, is that top-down (macro–>micro) causation is real and fundamental (i.e. irreducible to lower-level acts). For if causation is always bottom-up (micro–>macro) and never top-down, or alternatively, if top-down causation is real, but only happens because it has already been determined by some preceding occurrence of bottom-up causation, then our actions are simply the product of our body chemistry – in which case they are not free, since they are determined by external circumstances which lie beyond our control. But if top-down causation is real and fundamental, then a person’s free choices, which are macroscopic events that occur in the brain at the highest level, can constrain events in the brain occurring at a lower, sub-microscopic level, and these constraints then can give rise to neuro-muscular movements, which occur in accordance with that person’s will. (For instance, in the case I discussed above, relating to rows of ones and zeroes, the requirement that the columns must add up to 1 might result in to the neuro-muscular act of raising my left arm, while the requirement that they add up to 2 might result in the act of raising my right arm.)

As far as I’m aware, there’s no law of physics which rules out the idea that patterns of random events (such as radioactive decay events) might turn out to be non-random at the macro level, while remaining random at the micro- or individual level. Of course, as far ass we know, radioactive decay events are random at the macro level, but the same might not be true of random neuronal firings in the brain: perhaps here, scientists might find non-random large-scale patterns co-existing with randomness at the micro- level.

Putting it another way: even if laboratory experiments repeatedly failed to detect patterns in a random sequence of events over the course of time, this would not establish that these events are randomly distrubuted across space as well. Hence large-scale spatial patterns are perfectly compatible with temporal randomness, at the local level.

In her blog post, Dr. Hossenfelder challenges her readers to “write down any equation for any system that allows for something one could reasonably call free will.” It’s a challenge she has already met, with her free will function in part 3 of her ARXIV essay, in which “each decision comes down to choosing one from ten alternatives described by the digits 0 to 9”:

Here is an example: Consider an algorithm that computes some transcendental
number, τ, unknown to you. Denote with τn the n-th digit of the number after the
decimal point. This creates an infinitely long string of digits. Let tN be a time very
far to the future, and let F be the function that returns τN−i for the choice the agent
makes at time ti.

This has the following consequence: The time evolution of the agent’s state is
now no longer random. It is determined by F, but not (forward) deterministic: No
matter how long you record the agent’s choices, you will never be able to predict,
not even in principle, what the next choice will be…

Dr. Hossenfelder’s example is mathematically elegant, but it’s really not necessary, in order to salvage the idea of free will. All that is needed is to show that the the idea of top-down causation which is irreducible to preceding instances of bottom-up causation remains a valid one in physics, and that this, coupled with the suggestion that the mind can make non-random global selections from random sequences of events without destroying their local randomness, is enough to render the ideas of agent-causation and strong libertarian free will scientifically tenable. How the mind makes these selections and influences processes within the brain is a question for another day (for a discussion, see here and here). All that I have been concerned to show here is that no laws of physics are broken, even if one adopts a very robust version of libertarian free-will.

Yet more on mindless intelligence.

More on "Intelligent Design Without a Designer"
Brendan Dixon April 3, 2016 3:22 AM

A reader, Eric, writes to ask about my post "Nature 'Learns' to Create Complexity? Think Again":

Like Brendan, I work on developing computer models and software for scientific applications. His comments about models vs. reality were, of course, spot on. It did occur to me that there is one possible partial response to a point that was made. Brendan writes:

Worse, whatever is "learned" by that organism must be passed along to the children. So, unless the paper's authors subscribe to some form of Lamarckism, which is exceedingly unlikely, without a clear inheritance path all the training value is lost.

A neo-Darwinist could respond with the same kind of switch that the synthesis used to rescue the original version of Darwinism. Darwinism originally did have a Lamarckian flavor to it (which is why it opposed and resisted Mendelian genetics). With the neo-Darwinian synthesis, they dropped the Lamarkian aspects, embraced genetics, and proposed that the gains were built in through genetic variations.

In a similar way, someone now could say that the "learning" isn't Lamarkian. Rather, it is the genetic variations to GRNs that succeed in being passed on (in contrast to those that were weeded out). The correspondence with environmental conditions comes in the form of the natural selection filtering that comes after the fact of the genetic change.

Yet, if that is how it should be understood, the issues raised in the preceding paragraph about training "over time and space" are still relevant. The genetic "learning" would not be limited to the life of any single individual, but it still would be constrained to accumulating within a line of ancestry.

That would make the "learning" generational in nature. Instead of a single copy of a network collecting "millions of data sets," one would have to look along an organism's ancestral line to observe the inherited network receiveing a multitude of tweaks down through the successful generations.

At first glimpse, it might seem that this way of viewing it could succeed at making it work for the neo-Darwinist. However, it does come back to the details, such as the limited amount of successful tweaking that can take place in any single generation and the limited number of generations down to the present organism.

Quite simply, there does still seem to be a serious problem about accumulating the extent of learning that would be needed.

The other main thought I had was this. You cannot have a second time without having a first time. You cannot learn to use building blocks more effectively apart from first having building blocks that can be used somewhat effectively.

In my software, I know the value of modularization and being able to recombine components, but that doesn't happen by accident. I wouldn't be able to reuse composable parts if I did not first have such parts that allowed from recombination. Flexibility comes by design, and before one could have a flexible, adjustable, "educated" GRN, one would need first to have a GRN that from the start flexibly allows for "learning." Otherwise, one could not get off the ground.

Even granting for the sake of argument that GRNs can learn across generations, how do we expect that a learning GRN can first come to exist?

Darwinists are forever pushing their present problems aside by building on the idea that whatever they need already existed earlier (without explanation), whether it is functional information or GRNs that can learn.

By the way, if you haven't seen the movie Next, staring Nicholas Cage, I would suggest giving it a look. (It's available for streaming on Netflix.)

It's not a "great" movie in any sense, but it does do a very clever job at cinematically portraying what is essentially a visual allegory to the evolutionary perspective of a finding a winning path that has been filtered from among many other failed attempts. As with evolutionary thought, the attempts are temporally concurrent.

People who have seen this will more easily and more intuitively feel that such a strategy could work (so long as one does not delve into the messy details).

I appreciate Eric's thoughts. I suppose the answer depends on how the paper's authors envision the GRN learning. If it is no different than modification + selection that preserves those GRNs producing "better" phenotypes, then Eric's point is sound. And he is correct in that case to point out that an entire ancestral chain matters. If the GRN learns dynamically (which I don't believe was clear in the original paper), then inheritance remains a significant problem.

However, if Eric's perspective is correct and a GRN "learns" through descent with modification, the analogy with Neural Networks breaks down. Neural Networks succeed by changing the entire network in response to massive data sets (along with some notion of correctness). For example, imagine two critters: The GRN in one "learns" to adapt part of the network while the other adapts the other part. They cannot share that information (unless you can specify a mechanism by which they can mate and successfully blend what both "learned"). And adaptation in one is made without respect for the adaptation in the other. NNs succeed because the entire network adapts as a unit; that is, each node learns how to respond to inputs based on how the entire network has faired. You cannot teach one node at a time or even part of the network at a time -- the entire network responds. Training a NN one node at a time will, by definition, fail.

And, as Eric agrees, the quantity of data to succeed is massive. AlphaGo contained "millions" of connections across 12 (or 13?) layers (networks) in two different NNs. AlphaGo was originally fed roughly 30 million moves from 160,000 games, yet that was far from sufficient. It required more training by playing itself (I failed to find the number of moves evaluated during this phase, but I suspect it completed many more than 160,000 games). And then, to allow the search tree to run deep, they distributed its execution across over 2,000 CPUs (some of which were the specialized, high-performance CPUs used in video games). Even then, a small number of "hand crafted" rules lurked within (see here).

Comparing GRNs to NNs remains uninteresting given what we've learned about training NNs. If anything, what we've learned says that GRNs could not have been self-taught since they just don't have access to the necessary data or a means by which to ensure the entire GRN benefits from the training.

The quantity of data needed to train an NN is proportional (though not linearly) to the number of connections within the network. The more connections a network contains, the more training data necessary.

I do not know how many nodes or connections a GRN contains, but, in a way, it is immaterial: If the number of connections is small, the network cannot "recognize" anything significant. If it is large, then the data requirements will rapidly exceed that available. A small, trainable network will be uninteresting and a large, interesting network will be untrainable. (I like that statement. I believe it captures the challenge succinctly with a bit of rhythm.)


If someone were to respond by saying, "Ah, but we have thousands of GRNs," then they have a large network (where each node is itself a GRN, something akin to a deep learning problem) that will require massive quantities of data.

Patron saint of the master race?

Why Darwinism Can Never Separate Itself from Racism

 David Klinghoffer | @d_klinghoffer

 

It’s great to have insightful colleagues. Denyse O’Leary, with Discovery Institute’s Bradley Center for Natural and Artificial Intelligence, has been writing about evolution for years as well. Having read my post “The Return of John Derbyshire,” she points out something I hadn’t quite grasped. Now a lightbulb goes off. 

Inherent, Unavoidable

The thread of racism in Darwinian thinking isn’t a chance thing, a mere byproduct of Charles Darwin’s personal views as a “man of his time.” You think if Darwinism had emerged not in the dark age of the 19th century but in our own woke era, it would be different? No, it wouldn’t. The racism is inherent, unavoidable:

That’s just the difference between Darwinism and any type of creationism OR non-Darwinian approaches to evolution. In a Darwinian scheme, someone must be the official subhuman.
I have been trying to get that across for years. It’s why Darwinism can never get away from racism. Racism is implicit in the Darwinian belief system about how things happen.  Even if one’s creationism amounts to no more than the idea that humans have an immortal soul, it makes all humans equal for all practical purposes. Take that away and believe instead that humans are animals that slowly evolved from less-than-human creatures and a variety of things happen, none of them conducive to non-racism.

True, O’Leary has been saying this for a long while. As she wrote over at Uncommon Descent last year:

The problem is not merely that Darwin, a man of his age, was a racist. The problem is that his bias resulted in his and others distorting the fossil record to suit a racist worldview.

Those issues with the fossil record are the theme of most of paleontologist Günter Bechly’s recent writing at Evolution News. She goes on:

To “get past” the fact that Darwin was a racist, we must be willing to undo science that begins by assuming that non-European features are sub-human. But the “hierarchy of man” is rooted in the fundamental assumptions of the “Descent of Man,” the idea that Darwin popularized. Rooting it out would call so many things into question as to produce a crisis. What will we be left with?
Indeed. But then an even bigger problem looms: In any Darwinian scheme, someone must be the subhuman. If not the current lot (formerly, the “savages,” currently the Neanderthals and/or Homo erectus), who will it be?
If they aren’t found, the Darwinist is looking down the maw of some sort of creationism. It need not be theistic creationism. But it does mean that a momentous event happened with explicable swiftness, like the Big Bang or the origin of language, findings naturalists do not like precisely because of their creationist implications.
Surely these are the true reasons Darwinists simply can’t confront the race issue and get past it, and so they resort to long-winded special pleading.

A Minimal Concept

The word “creationism” is used unfairly as a cudgel against proponents of intelligent design. But fine, let’s entertain it for a moment, if only to designate a minimal concept like the philosophical one that says humans, while sharing biological common descent with other creatures, are uniquely endowed with souls bearing some sort of exceptional quality, however you characterize that. It could be a divine image, but need not be. The consistent materialist must deny all this.

The idea of racial equality, perfectly natural to a design perspective, can be achieved by the Darwinist only by continually and ruthlessly suppressing a built-in tendency. It requires bad faith: fooling himself about his own way of thinking. Like an irremediable birth defect, it’s never going to go away.

“Tell It on the Mountain”

Or it’s like driving a car with misaligned wheels that always pulls you in one direction and cannot ever drive straight without your exerting continuous effort toward correction. If you don’t fight it all the time, you’ll go off the road and crash into a nasty, muddy ditch, as folks like John Derbyshire have done. John and other “Race Realists” humiliate their fellow evolutionists by dancing in the muck.

The alternative is to get those wheels nicely aligned. Of course it’s possible to find people who believe in creation and who are also racists. You can find bad apples in any community of thinkers. But the key point is that the two ideas are permanently at odds with each other. Whereas Darwinism and racism are a match made in… Well, they’re conjoined twins, let’s put it that way.

“Klinghoffer,” Denyse advises, “tell Derbyshire he needs a louder mike. He should go tell it on the mountain. Worldwide.” Okay, done.

 

Insect navigator vs. Darwin.

Monarch Butterfly's Sun Compass Investigated in Flight Simulator
Evolution News & Views

The amazing story of how Monarch butterflies navigate from Canada to Mexico is beautifully recounted in Metamorphosis, the Beauty and Design of Butterflies. "Here's a butterfly species that does something truly spectacular," Thomas Emmel says in the film. Flying over two thousand miles without an experienced leader who has made the trip before, millions of these artistically-colored flyers arrive on schedule in the same trees their grandparents or great-grandparents had wintered in the previous year.

Somehow, with a brain the size of a pinhead and a body weighing less than an ounce, the butterfly contains hardware and software for long-range precision navigation, efficient energy utilization and genetic alterations that enable the "Methuselah generation" to survive ten times as long as their parents. Emmel comments that this phenomenon will likely occupy biologists' attention for centuries to come. Researchers at the University of Washington announced this month that they have "cracked the secrets" of one small aspect of this wonder: the monarch's internal time-compensated sun compass.

We saw from the film that the angle of the sun and its traverse through the daylight hours plays a role in the choice of flight direction. Using sunlight to navigate requires processing dynamic inputs:

"Their compass integrates two pieces of information -- the time of day and the sun's position on the horizon -- to find the southerly direction," said Eli Shlizerman, a University of Washington assistant professor. [Emphasis added.]
But how is this information processed in the butterfly's tiny brain? The compass needs to be integrated with the clock.

Monarchs use their large, complex eyes to monitor the sun's position in the sky. But the sun's position is not sufficient to determine direction. Each butterfly must also combine that information with the time of day to know where to go. Fortunately, like most animals including humans, monarchs possess an internal clock based on the rhythmic expression of key genes. This clock maintains a daily pattern of physiology and behavior. In the monarch butterfly, the clock is centered in the antennae, and its information travels via neurons to the brain.
We saw electron micrographs of the antennae in the film. Covered with scales and tiny hairs, these organs are the sites for odor detection, enabling the monarchs to find mates and the females to find their host plants from miles away. Now we learn they are clocks, too:

In their model, two neural mechanisms -- one inhibitory and one excitatory -- controlled signals from clock genes in the antennae. Their model had a similar system in place to discern the sun's position based on signals from the eyes. The balance between these control mechanisms would help the monarch brain decipher which direction was southwest.
Using models and live butterflies in a flight simulator, the researchers determined how they get back on track if blown off course. There's a "separation point" that determines whether the individual will turn left or right. That point changes throughout the day. The insect's onboard computer won't let it cross the separation point, even if it requires a longer path to get back on course. The scientists also shed light on how the butterflies readjust their compasses for the return trip.

Their model also suggests a simple explanation why monarch butterflies are able to reverse course in the spring and head northeast back to the United States and Canada. The four neural mechanisms that transmit information about the clock and the sun's position would simply need to reverse direction.
"And when that happens, their compass points northeast instead of southwest," said Shlizerman. "It's a simple, robust system to explain how these butterflies -- generation after generation -- make this remarkable migration."

Simple, simply -- while appreciating the insights our neighbors at UW have gained, such talk is premature. There's a lot more going on. For one thing, not all individual butterflies head southwest and return northeast. The flight paths from Canada begin on different bearings and converge into a narrow flight path in southern Texas. Also, as Metamorphosis shows, a few individuals take a direct route across the Gulf of Mexico. Then, they all switch direction at a certain point, heading west through a pass toward the Trans-Volcanic Range. Then, within those mountains, they converge on specific trees in 12 known overwintering spots.

Time of day and sun position are necessary, but not sufficient, to explain these precise behaviors. If the researchers feel they have "cracked the secret" of maintaining a particular bearing, they have left all these other secrets unexplained. Their model only shows the bare outlines of a sophisticated, integrated system. The paper in Cell Reports says:

A long-standing, fundamental question about monarch migration has been how the circadian clock interacts with the changing position of the sun to form a time-compensated sun compass that directs flight. Here, we propose a neuronal model for both encoding of the sun's azimuthal position, and molecular timekeeping signals, and how they can be compared to form a time-compensated sun compass. Our results propose a simple neural mechanism capable of producing a robust time-compensated sun compass navigation system through which monarch butterflies could maintain a constant heading during their migratory flight.
But as we just said, the butterflies don't keep a constant heading. They make turns. And what tells individuals in Minnesota to head south and individuals in Pennsylvania to head southwest? Do their offspring for the three generations on the return trip keep the target information embedded in their memories? A compass is no good without a map. Both are no good without a brain to read them. Furthermore, as we reported about Bogong moths, some lepidopterans can reach their long-range destinations in the dark!

The researchers identified four genes that keep time by oscillating their expression levels. They identified how the compound eye determines azimuth and bearing even when the sun's position is changing throughout the day. A butterfly, however, needs much more. It needs controls for altitude, pitch, and yaw. It needs a map of where it has to go. And it needs to monitor resources to ensure it has the energy to get there.

Nevertheless, we're glad for any and all research that sheds light on the details of monarch butterfly navigation, especially when it can lead to intelligently designed applications that benefit everyone:

The model that we have built closes the loop between the time and azimuth stimuli and orientation control. As such, it provides an important framework for future studies of the monarch sun compass. Our framework can be used to design electrophysiological and flight recordings experiments to compare responses in monarchs' neurons and model units and to determine the detailed architecture of neural circuits that implement the integration mechanism postulated by our model. It also provides a simple mechanism for navigation that can be used in devices that do not have the benefit of a global positioning system.

A complex, functional system that, when partially understood, can be "used to design" something else must have been designed itself.

How OOL science can earn some respectability.

Announcing New Sewell Prize in Biological Origins Studies!
David Klinghoffer | @d_klinghoffer

Over at Uncommon Descent, mathematician Granville Sewell announces a new prize he will be administering. It sets a fascinating challenge but offers an enviable reward:

I plan to award a prize to anyone who can invent a non-trivial 3D machine which can replicate itself. The machine must be able to make copies of itself without human intervention, except possibly to supply the raw materials. Basically a 3D printer which can print a copy of itself which retains the ability to print a copy of itself, which… A page which can be photocopied does not count, because it is the photocopier which actually makes the copy, unless the photocopy machine also makes a copy of itself; a computer program which duplicates itself does not count unless the computer it runs on makes a copy of itself also.

The reward isn’t cash but something even better: 

The prize: the right to speculate about how life originated. Leave your artificial species alone and see how many generations it lasts before going extinct. If it makes accurate copies of itself for 100+ generations, then you also get to speculate about how genetic duplication errors might accumulate into major evolutionary advances.

Now go to it, you proponents of unguided abiogenesis and evolution through all sorts of brute unintelligent, and only unintelligent, natural forces. The first ever Sewell Prize in Biological Origins Studies awaits!

Blinded by fuzzy math?

Behe on Darwinism’s “Socially Inherited Dependence on Classical Yet Irrelevant Math”
David Klinghoffer | @d_klinghoffer

“Natural selection, irreducible complexity, and random mutation all reinforce each other to make Darwinian evolution very limited,” explains biochemist Michael Behe on a new ID the Future episode. That means Behe must tackle a tough question: if the limits of Darwinian evolution are so clear, as he shows in his new book Darwin Devolves, why do gifted scientists like Richard Lenski and Joseph Thornton persist in hanging on to the failed theory, against the evidence of their own experiments? 

Talking with host Andrew McDiarmid, Behe traces the errant thinking to an outdated mathematical picture taken from Ronald Fisher (1890-1962) and his 1930 book, The Genetical Theory of Natural Selection. This highly influential work was written before scientists knew what genes actually are. It’s not surprising that Fisher missed the role of broken genes in containing the creative potential of unguided evolution.

Through “a socially inherited dependence on classical yet irrelevant math,” present-day researchers are saddled with Fisher’s own “hopeful ignorance.” Download the podcast or listen to it here.
