More education less indoctrination II

Nature Agrees: Science Students Should "Actively Grapple with Questions" Not Just "Listen to Answers"

Discovery Institute has long promoted critical thinking in the science classroom, noting that it is remarkably scarce in the way evolution is taught. Despite media opposition to academic freedom laws, active engagement, asking questions, and thinking analytically have been demonstrated to promote student understanding and success.

That insight has now been confirmed by no less a source than Nature, the world's most prestigious scientific journal, in collaboration with Scientific American. The two journals got together to produce an issue on the theme, showing that STEM (science, technology, engineering, and mathematics) instruction is due for reform. They note, "[S]tudents gain a much deeper understanding of science when they actively grapple with questions than when they passively listen to answers."

In the cover package, "Building the 21st Century Scientist: Why Science Education is More Important than Ever," Nature emphasizes research demonstrating that active engagement increases student understanding and success in STEM classes. They highlight various types of interactive instruction, and present strategies for teachers to improve their instructional methods and institutions to incentivize change.

What Is Active Learning?

Jay Labov, a senior education advisor from the U.S. National Academy of Sciences, describes active engagement as "learning content not as something you memorize and regurgitate, but as raw material for making connections, drawing inferences, creating new information -- learning how to learn."

Unfortunately, this is not the norm for science classes. Jonathan Osborne wrote in 2010 in the journal Science:

Typically, in the rush to present the major features of the scientific landscape, most of the arguments required to achieve such knowledge are excised. Consequently, science can appear to its students as a monolith of facts, an authoritative discourse where the discursive exploration of ideas, their implications, and their importance is absent (7). Students then emerge with naïve ideas or misconceptions about the nature of science itself -- a state of affairs that exists even though the National Research Council; the American Association for the Advancement of Science; and a large body of research, major aspects of which are presented here, all emphasize the value of argumentation for learning science (8-10).

Active learning can take many forms, but it generally repudiates traditional lecture-style teaching. Neuroscientist Sarah Leupen, for example, doesn't ask her physiology class to name the sensory nerves in the leg. Instead, says Nature, she poses the following question to the students:

You're innocently walking down the street when aliens zap away the sensory neurons in your legs. What happens?

1. Your walking movements show no significant change.
2. You can no longer walk.
3. You can walk, but the pace changes.
4. You can walk, but clumsily.

"We usually get lots of vigorous debate on this one," Leupen said. (For curious readers, the answer is d).

And there are many other classroom strategies for fostering scientific inquiry. Nature highlights Little Scientists' House, a program developed in Germany for children between three and six years old, but spreading worldwide. At Little Scientists' House, students learn to ask questions about the world around them and look for answers by simple observation and experimentation.

In one exercise, students guessed whether more water could accumulate on the head of a euro coin or other currency. One student thought that the smaller coin, which was worth more money, would hold more water -- and the class proceeded to try out his idea. "In the end, the children could not come to a definitive answer, but that is OK, says [kindergarten teacher Christina] Jeuthe. The point is to spark questions, and a conviction that they can be explored rationally."

On the college level, the University of Richmond in Virginia has begun offering introductory, interdisciplinary science courses that explore real science questions such as "antibiotic resistance and cells' response to heat." Outside of the traditional classroom setting, active learning can encompass activities from involving high school students in real scientific research projects to materials-based outdoor exploration.

What about Evolution?

Eugenie Scott, former executive director of the National Center for Science Education, has said, "There are no weaknesses in the theory of evolution." No matter what your stance is on evolution, however, treating scientific theories as unquestionable fact doesn't make sense.

At Discovery Institute, we recommend teaching both the scientific strengths and scientific weaknesses of evolutionary theory. Students should not only hear about similarities in DNA sequences between species and antibiotic-resistant strains of bacteria, but also grapple with the Cambrian explosion and the intricacies of the cell.

We put it this way in our Educator's Briefing Packet:

What Is a Suggested Plan for Teaching a Unit on Neo-Darwinian Evolution?
Objective education means that students must be allowed to form and express their own opinions. An objective unit covering neo-Darwinian evolution might look something like this:

• First, cover the required curriculum by teaching the material in the textbook. Ensure that students understand the scientific arguments for neo-Darwinian evolution. (1-2 weeks)


• Next, spend a few days discussing scientific criticisms of neo-Darwinian evolution. The supplementary textbook Explore Evolution, the DVD Investigating Evolution, and the Icons of Evolution Study Guide are potential resources. Encourage students to think critically. (2-3 days)


• Finally, consider allowing students to spend a couple days wrestling with the data and forming their own opinions. This could include in-class debates, or an assignment where students write a position statement on neo-Darwinian evolution. In these exercises, students may defend whatever position they wish, but must justify it using only scientific evidence and scientific arguments. (1-2 days)

Most public school curricula stop after step 1, missing out on the benefits from steps 2 and 3. Some might claim those extra steps would take too much time. But teaching the modern neo-Darwinian theory of evolution in an objective fashion need not take any more time than the 2-3 weeks typically spent on an evolution unit.
More importantly, any extra time taken to teach this topic objectively is not wasted -- it will help students better understand the evidence, better appreciate scientific reasoning, and fulfill standards requiring critical thinking and use of the inquiry method. Finally, this approach will be welcomed by students who find this topic engages their interest in science.

Building 21st-Century Scientists

It's high time for a change. Science education, especially at the university level, faces some hurdles. Nature says, "A study tracking 17,000 post-secondary students in the United States and Puerto Rico found that only two-fifths of those who enrolled in a STEM discipline went on to obtain a degree in the field, or were still studying for one 6 years later." On the other hand, Nature notes that research at the University of Washington in 2014 surveyed 225 studies of teaching in STEM fields and found that active engagement decreased failure rates by one-third.

Carl Wieman, a physicist at Stanford who won the 2001 Nobel Prize in his field, began advocating for science education reform after interacting with newly graduated scientists who "had done really well as undergraduates, but couldn't do research." Today, along with prominent journals such as Nature, Scientific American,and Science, he promotes active engagement in the classroom.

Nature concludes its keynote editorial, "But change is essential.... In an era when more of us now work with our heads, rather than our hands, the world can no longer afford to support poor learning systems that allow too few people to achieve their goals."

That's right. Teaching the controversy over origins would be a step towards better overall science education. Where the approach has been adopted already, it trains students to think analytically and examine the evidence -- in all scientific fields. It awakens interest in the issue of origins by inviting students to confront the research themselves. And students who succeed in courses on evolution (as well as other STEM courses) are more likely to pursue degrees in these fields. Inquiry in the classroom paves the way for inquiry in the lab.

Two horrific killings of children put Israel at a crossroads

By Nic Robertson, CNN

Jerusalem (CNN)Ori and Mika Banki did what no parent should ever face.

On Monday they buried their daughter Shira. She was just 16.

The girl they said was "charming, happy, lively and beloved" has been ripped from their lives.

"With no purpose but with stupidity, evilness and recklessness, her life came to an end," the family said in a statement. "Bad things happen to good people and the worst thing happened to our amazing child."Israelis are familiar with sudden death. But this is different. Not just because Ori and Mika Banki's anguish is impossible for any parent to insulate against, but because Shira's brutal killing questions the very lives people live here.

It puts Israel at a crossroads.

Vilified through history by so many for so long, Jews are accustomed to sticking up for one another. But, in the light of Shira's murder, the question now is: Can they still do that?

Repeat attacker stabs 6 at Jerusalem gay pride parade, police say

Vilified through history by so many for so long, Jews are accustomed to sticking up for one another. But, in the light of Shira's murder, the question now is: Can they still do that?

Shira died Sunday after she was stabbed at a gay pride rally in Jerusalem Thursday while supporting the rights of her friend and others to be themselves.She was quite simply upholding one of the founding principles of the Israeli State: tolerance.

To many in the outside world familiar with the struggle between the Israeli state and Palestinians, that idea may seem hard to grasp. But to most Israelis, tolerance is what makes Israel a good place to live.

Tel Aviv is widely rated as one of the world's most tolerant places for gays. Above others, the coastal city seems to embody what Israel's founders declared in 1948: The state "will ensure equality of social and political rights to all its inhabitants irrespective of religion race or sex."

In the past few days that notion of tolerance has been challenged, not just by the brutal killing of bubbly 10th-grader Shira, but by the death of Ali Saad Dawabsha, an 18-month-old Palestinian toddler.

Yishai Shlissel, an ultra-orthodox Jew, stabbed Shira and was photographed during his attack on her and five others. He had just been released from jail for a similar attack 10 years ago. Suspicion for Ali's murder also points, unproven as yet, towards Jewish extremists.

Ali was sleeping in his house later that same Thursday in the tiny West Bank village of Duma when arsonists struck. His mother, father and 4-year-old brother were badly burned too. The house was daubed in Hebrew graffiti denoting a "price tag" attack.The so called price tag attacks began in 2008 and eere blamed on extremist Israeli settlers driven by a religious conviction that they should live on the land of their ancestors. The "price" was for settlements the government forced them to give up and revenge for Palestinian attacks on settlers.

Recent Israeli newspaper reports suggest Israeli's intelligence service Shin Bet believes that the right-wing extremists behind these attacks intend to escalate atrocities to destabilize Israel's government.

Regardless, both brutal killings have triggered an examination of the Jewish state and its tolerance, questioning whether that very principle has allowed homegrown extremists to go too far.

Israel's President Reuven Rivlin struck a chord saying "more than shame, I feel pain. The pain over the murder of a little baby. The pain over my people choosing the path of terrorism and losing their humanity, their path is not the path of the state of Israel."

Israel's security cabinet met this weekend determining that the killers be brought to justice by all legal means necessary and, for the first time, authorizing "administrative detention" for Jewish citizens -- a security measure implemented to stop attacks and one that is more usually applied to Palestinians.

The killings have also driven a deeper wedge between left and right, with the left blaming the right-wing government's tolerance of settlers as the root of the killing of Ali.

As they prepared to bury Shira, Mika and Ori Banki called for "less hate and more tolerance"

They are holding her funeral away from scrutiny and the public lament that surrounds her death. They want a quiet civil service, not a religious one.

It's the way they raised their family, they say.

In a newspaper interview three years ago, they told a reporter that raising Shira and her three siblings was "all about quality. To raise good citizens, children who will bring happiness to themselves and to their surroundings."

In her short life Shira did just that.

In her death, her country at a crossroads, many here hope her legacy will live on.

Genesis Vs.Young earth Creationism.The Watchtower Society's commentary

THE BIBLE’S VIEWPOINT:Creation


Did God create the earth in just six 24-hour days, as some creationists claim?
“In the beginning God created the heavens and the earth.”—Genesis 1:1.
WHAT THE BIBLE SAYS: God created the universe, including the earth, in the indefinite past—“in the beginning,” as Genesis 1:1 says. Modern science agrees that the universe had a beginning. A recent scientific model suggests it to be almost 14 billion years old.
The Bible also describes six “days” of creation. However, it does not say that these were 24-hour days. (Genesis 1:31) In fact, the Bible uses the word “day” to refer to various lengths of time. For example, it calls the entire period of creation “the day that Jehovah God made earth and heaven.” (Genesis 2:4) Evidently, these “days” of creation lasted many thousands of years.—Psalm 90:4.WHY IT MATTERS:The false ideas of creationists could lead you to dismiss the Bible altogether. On the other hand, if the Bible actually contains a credible account of creation, you stand to benefit from its storehouse of “practical wisdom.”—Proverbs 3:21.Did God use evolution to create life on earth?:“God said: ‘Let the earth bring forth living creatures according to their kinds.’”—Genesis 1:24.WHAT THE BIBLE SAYS: God did not make life in a simple form and allow it to evolve into more complex forms. Instead, he created basic “kinds” of complex plants and animals, which then reproduced “according to their kinds.” (Genesis 1:11, 21, 24) This process, which continues today, has resulted in the earth being filled with the same “kinds” of life that God originally created.—Psalm 89:11.
The Bible does not specify how much variation can occur within a kind, as might result when animals within a kind interbreed and adapt to their environment. While some view such adaptations as a form of evolution, no new kind of life is produced. Modern research supports the idea that the basic categories of plants and animals have changed little over vast periods of time.
WHY IT MATTERS: The Bible’s scientific accuracy in describing basic “kinds” of life strengthens its credibility in other areas, including history and prophecy.
 Where did the raw material of the universe come from?:“I stretched out the heavens with my own hands.”—Isaiah 45:12
 WHAT THE BIBLE SAYS:God is the Source of infinite power, or energy. (Job 37:23) This is significant, because scientists have learned that energy can be converted into matter. The Bible says that God himself is the Source of the “vast dynamic energy” that produced the universe. (Isaiah 40:26) God promises to use his power to sustain his creation, for the Bible says regarding the sun, moon, and stars: “[God] keeps them established forever and ever.”—Psalm 148:3-6.
 WHY IT MATTERS: The astronomer Allan Sandage once said: “Science cannot answer the deepest questions. As soon as you ask why is there something instead of nothing, you have gone beyond science.” Not only does the Bible explain creation in a way that harmonizes with science but it also answers questions that science cannot—such as, What is God’s purpose for the earth and for mankind?*

And now,armor plated doubt.

Earliest Comb Jellies Wore Armor

Evolution News & Views July 29, 2015 3:29 AM

What does it take to wear armor? An animal has to be able to make the material and put it where it belongs. To be functional, the armor cannot interfere with the animal's movement. And the animal cannot simply glue sand particles on its exterior in a haphazard way. The appropriate materials, directed by genetic instructions, must be manufactured and placed holistically so that the finished armor provides a beneficial function. It would be surprising, under an evolutionary view, to find such a complex system in the earliest animal fossils. But that's what Chinese paleontologists discovered in their country's early Cambrian rocks.

Phylum Ctenophora (cilia-bearing) has about 150 living representatives. While most of them have tentacles, none have hard parts. Varying in size from a few millimeters to over a meter, they resemble jellyfish (phylum Cnidaria) in being gelatinous and transparent, but are distinct in having eight-fold radial symmetry with comb-like rows of fused cilia that propel them around. Some living comb jellies give stunning light shows as their comb rows reflect light in rainbows of iridescent colors, making them resemble alien spacecraft (watch on YouTube). Though not bilaterians, they have complex body plans with a buoyancy organ called a statolith, muscles, a nervous system, an alimentary canal, and the ability to control the direction of their locomotion. The phylum made its appearance in the earliest Cambrian layers, dated 520 million years ago. That takes us to the Chengjiang biota in China, one of the finest exposures of early Cambrian fossils in the world.

Seven Chinese researchers found beautifully preserved comb jellies in lower Cambrian strata -- three new species and three reclassified species -- all with armor. Their open-access paper in Science Advances, "A vanished history of skeletonization in Cambrian comb jellies," shows the photographs of the fossils along with diagrams of how they probably looked. Armored struts and plates are arranged in complex shapes along the animals' exterior, following the eight-fold symmetry and making up complex curves. One of the species has spines along its outer struts. The fossil hunters were quite surprised:

They share a basic body plan characterized by a tentacleless and octaradial body with an oral-aboral axis, eight rigid struts (termed here "spokes") radiating from the aboral end and arched to converge to the oral end, eight soft-bodied flaps or lobes supported by the spokes, eight pairs of ctene rows, a conspicuous apical (or aboral) organ walled by eight rigid platesand housing a spheroidal or ellipsoidal statolith, and an oral region surrounded by eight apiculate lappets...

The eight arcuate spokes [in one species] bear robust spines (Fig. 2, L to N, and figs. S4 to S6) and retain their structural integrity even when disarticulated, suggesting a remarkable degree of sclerotization. [Emphasis added.]

The plates have "considerable rigidity," they noticed, retaining their integrity even when separated. Some of the hard parts protrude into different layers of sediments. It's not clear what the armor is made of, but the authors presume it is chitin, the same protein that makes up the exoskeleton of arthropods. "The spokes and apical plates of scleroctenophores were likely cuticular or chitinous in composition, but the presence of minerals in their skeletons cannot be completely ruled out, given that the epidermis of extant ctenophores can produce Mg-Ca carbonates that partially form the statolith," they say. The statoliths of some fossil specimens even preserve some organic carbon.

The authors are not sure about the function of the armor, but indulge in some evolutionary speculation. The typical evolutionary explanation is to imagine an "arms race" that forced the animals to defend themselves against a new class of predators. It seems obvious, though, that nothing about predation can cause a brainless animal to build a suit of armor. It could more easily just go extinct.

What's even more remarkable (a word they use themselves) is that the ctenophores are not alone in being armored compared to living counterparts. They use this observation to support a view from the late Stephen Jay Gould that evolution is highly unpredictable:

The occurrence of sclerotized and armored skeletons inCambrian representatives of several animal groups -- including entoprocts, phoronids, lobopods, scalidophorans, and now ctenophores that are exclusively soft-bodied among modern survivors -- is a remarkable phenomenon. The independent skeletonization among these diverse Cambrian animals provides indirect evidence for an intensified level of ecological interactions (for example, arms race) and also highlights the importance of paleontological data in illuminating theevolutionary legacy that would be otherwise inaccessible by studying living animals alone. The widespread occurrence of skeletonization echoes Stephen Jay Gould's view of the striking morphological disparity of many animal phyla during their Cambrian debut, and the contrasting evolutionary trajectories of skeletonized cnidarians and ctenophores also elucidate the contingent fate of evolutionary innovations such as skeletonization.

This kind of explanation serves only to protect Darwinian evolution from the evidence. If animals are similar, they evolved. If animals are different, they evolved. But the authors noticed that the "morphological disparity" in the Cambrian explosion exists not only between phyla, but between species within phyla. Earlier, they referred to the explosion:

Here, we report several sclerotized and armored ctenophore species, based on new material and reinterpretation of previously published material from the early Cambrian Chengjiang biota (ca. 520 Ma). Along with armored Cambrian entoprocts, phoronids, lobopods, and scalidophorans, the new fossils suggest a vanished Cambrian history of skeletonization in multiple animal groups, imply the ecological importance of skeletonization in theCambrian explosion, and highlight the remarkable morphological disparity in certain Cambrian animal clades relative to their modern survivors.

A "vanished Cambrian history of skeletonization in multiple animal groups" is inconsistent with Darwinian evolution. "Ecological importance" is incapable of producing genetic programming for an armored skeleton. "Morphological disparity" at the earliest onset of complex animals is the opposite of Darwin's image of a branching tree gradually separating into more and more complex types.

Designers, by contrast, know how to apply a common solution in different applications. That's why it's unsurprising to see complex armor in disparate groups from the beginning.

Stephen Meyer did not go into detail about ctenophores in Darwin's Doubt, other than to note they are among the phyla that suddenly appeared in the Cambrian explosion (p. 32). But this new revelation that ctenophores are more complex than originally realized, possessing elaborate armor, certainly reinforces his contention that "the best explanation for the explosion of information necessary for the Cambrian animals... remains intelligent design" (see the Epilogue in the paperback edition, p. 448).

A time to punish:The Watchtower Society's commentary.

When Is There a Basis for Taking Offense?

AT ECCLESIASTES 7:9, the Bible states: “The taking of offense is what rests in the bosom of the stupid ones.” This verse shows that we should not be overly sensitive when someone offends us; rather, we should be forgiving.

However, is Ecclesiastes 7:9 saying that we should never be offended by anything or anyone, that we are to forgive all offenses regardless of how severe or how frequent they are and not do anything about them? Should we be unconcerned about our giving offense by word or action because we know that the one offended should be forgiving? This cannot be the case.


Jehovah God is the epitome of love, mercy, forgiveness, and long-suffering. Yet, in the Bible, he is many times spoken of as being offended. When the offense was severe, he took action against the offenders. Consider some examples.

Offenses Against Jehovah.

The account at 1 Kings 15:30 speaks of the sins of Jeroboam “with which he caused Israel to sin and by his offensiveness with which he offended Jehovah.” At 2 Chronicles 28:25, the Bible says regarding King Ahaz of Judah: “He made high places for making sacrificial smoke to other gods, so that he offended Jehovah the God of his forefathers.” Another example is found at Judges 2:11-14: “Israel fell to doing what was bad in the eyes of Jehovah and serving the Baals . . . , so that they offended Jehovah. . . . At this Jehovah’s anger blazed against Israel, so that he gave them into the hands of the pillagers.”

There are other things that offended Jehovah and that called for strong action. For example, at Exodus 22:18-20, we read: “You must not preserve a sorceress alive. Anyone lying down with a beast is positively to be put to death. One who sacrifices to any gods but Jehovah alone is to be devoted to destruction.”

Jehovah did not continually forgive the major offenses of ancient Israel when they kept offending him and did not show true repentance. Where there was no true repentance and no actions to indicate that there was a turning around to obey Jehovah, God eventually gave the perpetrators up to destruction. This happened on a national scale in 607 B.C.E., at the hands of the Babylonians, and again in 70 C.E., at the hands of the Romans.


Yes, Jehovah takes offense at the bad things that people say and do, and he even executes unrepentant offenders whose sins are gross. But does this put him in the category of those of whom Ecclesiastes 7:9 speaks? Not at all. He is justified in taking offense at gross sins and always judges fairly. The Bible says of Jehovah: “Perfect is his activity, for all his ways are justice. A God of faithfulness, with whom there is no injustice; righteous and upright is he.”—Deuteronomy 32:4.

Major Offenses Against Individuals

Under the Law that God gave to ancient Israel, there were serious consequences for major offenses against individuals. For instance, if a thief came into a house at night and the householder killed him, there was no bloodguilt on the part of the householder. He was an innocent victim of a major crime. Hence, we read: “If a thief should be found in the act of breaking in and he does get struck and die, there is no bloodguilt for [the householder].”—Exodus 22:2.

A woman who has been raped has a right to be highly offended, as this is a major crime in God’s eyes. Under the Mosaic Law, a man who raped a woman was to die “just as when a man rises up against his fellowman and indeed murders him.” (Deuteronomy 22:25, 26) While we are no longer under that Law, it gives us insight into how Jehovah feels about rape—a horrible wrong.


In our time, rape is also a major crime with severe penalties. The victim has every right to report the matter to the police. In this way the proper 
authorities can punish the offender. And if the victim is a minor, the parents may want to initiate these actions.(emphasis mine)


Lesser Offenses.


However, not all offenses require action by the authorities. Thus, we should not want to take undue offense at the relatively minor mistakes that others make, but we should be forgiving. How often should we forgive? The apostle Peter asked Jesus: “Lord, how many times is my brother to sin against me and am I to forgive him? Up to seven times?” Jesus answered: “I say to you, not, Up to seven times, but, Up to seventy-seven times.”—Matthew 18:21, 22.

On the other hand, there is a continuing need for us to work on our Christian personality to try to minimize giving offense. For instance, when you deal with others, are you at times blunt, tactless, insulting? Such ways are likely to offend. Rather than blaming the victim for taking offense and feeling that the burden of forgiveness is on him, the offender needs to realize that he is the reason that the person took offense. The offender needs to work on controlling his actions and speech so as not to give offense in the first place. This effort will reduce the number of times we hurt the feelings of others. The Bible reminds us: “There exists the one speaking thoughtlessly as with the stabs of a sword, but the tongue of the wise ones is a healing.” (Proverbs 12:18) When we offend others, even if we did not intend to do so, our making an apology goes a long way toward remedying the situation.

God’s Word shows that we should “pursue the things making for peace and the things that are upbuilding to one another.” (Romans 14:19) When we are tactful and kind, the proverb applies: “As apples of gold in silver carvings is a word spoken at the right time for it.” (Proverbs 25:11) What a pleasant and delightful impression that leaves! Mild, tactful speech can even change the rigid attitudes of others: “A mild tongue itself can break a bone.”—Proverbs 25:15.

Hence, God’s Word counsels us: “Let your utterance be always with graciousness, seasoned with salt, so as to know how you ought to give an answer to each one.” (Colossians 4:6) “Seasoned with salt” means that we make our expressions tasteful to others, thereby reducing the possibility of giving offense. In both word and deed, Christians strive to apply the Bible’s admonition: “Seek peace and pursue it.”—1 Peter 3:11.


Thus, Ecclesiastes 7:9 must mean that we should refrain from taking offense at the relatively minor sins of others. These may be the result of human imperfection or may even be deliberate yet not gross. But when an offense is a major sin, it is understandable that the victim may be offended and may choose to initiate appropriate action.—Matthew 18:15-17.

The Watchtower Society's commentary on the book of Jeremiah

JEREMIAH, BOOK OF

Prophecies and a historical record written by Jeremiah at the direction of Jehovah. Jeremiah was commissioned as prophet in the 13th year of King Josiah (647 B.C.E.) to warn the southern kingdom, Judah, of her impending destruction. This was less than a century after the prophet Isaiah’s activity and the fall of Israel, the northern kingdom, to the Assyrians.

Arrangement. The book is not arranged chronologically, but, rather, according to subject matter. Dating is presented where necessary, but the majority of the prophecies are applicable to the nation of Judah throughout the general period of the reigns of Josiah, Jehoahaz, Jehoiakim, Jehoiachin, and Zedekiah. God repeatedly told Jeremiah that the nation was incorrigibly wicked, beyond reform. Yet those with right hearts were given full opportunity to reform and find deliverance. As to being prophetic for our day, the arrangement does not affect the understanding and application of Jeremiah’s writings.

When Written. For the most part, the book of Jeremiah was not written at the time he declared the prophecies. Rather, Jeremiah evidently did not put any of his proclamations into writing until he was commanded by Jehovah, in the fourth year of King Jehoiakim (625 B.C.E.), to dictate all the words given him by Jehovah to date. This included not only words spoken about Judah in Josiah’s time but also proclamations of judgment on all the nations. (Jer 36:1, 2) The resulting scroll was burned by Jehoiakim when Jehudi read it to him. But Jeremiah was ordered to write it over, which he did through his secretary Baruch, with many additional words.—36:21-23, 28, 32.

The remainder of the book was evidently added later, including the introduction, which mentions the 11th year of Zedekiah (Jer 1:3), other prophecies that Jeremiah wrote down at the time he was to deliver them (30:2; 51:60), and the letter to the exiles in Babylon (29:1). Additionally, the proclamations uttered during the reign of Zedekiah and the accounts of the events after Jerusalem’s fall, down to about 580 B.C.E., were added later. It may be that, although the scroll written by Baruch was the basis for a large part of the book, Jeremiah afterward edited and arranged it when adding later sections.

Authenticity. The authenticity of Jeremiah is generally accepted. Only a few critics have challenged it on the basis of the differences in the Hebrew Masoretic text and the Greek Septuagint as found in the Alexandrine Manuscript. There are more variations between the Hebrew and the Greek texts of the book of Jeremiah than in any other book of the Hebrew Scriptures. The Greek Septuagint is said to be shorter than the Hebrew text by about 2,700 words, or one eighth of the book. The majority of scholars agree that the Greek translation of this book is defective, but that does not lessen the reliability of the Hebrew text. It has been suggested that the translator may have had a Hebrew manuscript of a different “family,” a special recension, but critical study reveals that this apparently was not the case.

The fulfillment of the prophecies recorded by Jeremiah, together with their content, strongly testifies to the book’s authenticity. Among the numerous prophecies of Jeremiah are those listed on the chart on page 34.

Principles and Qualities of God. Besides the fulfillments that we have listed, the book sets forth principles that should guide us. It stresses that formalism is of no value in God’s eyes but that he desires worship and obedience from the heart. The inhabitants of Judah are told not to trust in the temple and its surrounding buildings and are admonished: “Get yourselves circumcised to Jehovah, and take away the foreskins of your hearts.”—Jer 4:4; 7:3-7; 9:25, 26.

The book furnishes many illustrations revealing God’s qualities and his dealings with his people. Jehovah’s great loving-kindness and mercy are exemplified in his delivering a remnant of his people and finally restoring them to Jerusalem, as prophesied by Jeremiah. God’s appreciation and consideration for those showing kindness to his servants and his being the Rewarder of those who seek him and show obedience are highlighted in his care for the Rechabites, for Ebed-melech, and for Baruch.—Jer 35:18, 19; 39:16-18; 45:1-5.

Jehovah is brilliantly portrayed as the Creator of all things, the King to time indefinite, the only true God. He is the only one to be feared, the Corrector and Director of those calling on his name, and the one under whose denunciation no nation can hold up. He is the Great Potter, in whose hand individuals and nations are as clay pottery, for him to work with or destroy as he pleases.—Jer 10; 18:1-10; Ro 9:19-24.

The book of Jeremiah reveals that God expects the people bearing his name to be a glory and a praise to him and that he considers them close to him. (Jer 13:11) Those who prophesy falsely in his name, saying “peace” to those with whom God is not at peace, have to account to God for their words, and they will stumble and fall. (6:13-15; 8:10-12; 23:16-20) Those standing before the people as priests and prophets have great responsibility before God, for, as he told those in Judah: “I did not send the prophets, yet they themselves ran. I did not speak to them, yet they themselves prophesied. But if they had stood in my intimate group, then they would have made my people hear my own words, and they would have caused them to turn back from their bad way and from the badness of their dealings.”—23:21, 22.

As in other books of the Bible, God’s holy nation is considered to be in relationship to him as a wife, and unfaithfulness to him is “prostitution.” (Jer 3:1-3, 6-10; compare Jas 4:4.) Jehovah’s own loyalty to his covenants, however, is unbreakable.—Jer 31:37; 33:20-22, 25, 26.

Many are the fine principles and illustrations in the book, upon which the other Bible writers have drawn for reference. And many other pictorial and prophetic patterns are found that have application and vital meaning to the modern-day Christian and his ministry.

HIGHLIGHTS OF JEREMIAH

A record of Jehovah’s judgment proclamations through Jeremiah, as well as an account of the prophet’s own experiences and of Babylon’s destruction of Jerusalem

Writing was begun about 18 years before Jerusalem fell, and was completed some 27 years after that event

Youthful Jeremiah is commissioned as a prophet

He will have “to tear down” as well as “build” and “plant”

Jehovah will strengthen him for the commission (1:1-19)

Jeremiah fulfills his commission “to tear down”

He exposes the wickedness in Judah and proclaims the certainty of Jerusalem’s destruction; the presence of the temple will not save the unfaithful nation; God’s people will be exiles for 70 years in Babylon (2:1–3:13; 3:19–16:13; 17:1–19:15; 24:1–25:38; 29:1-32; 34:1-22)

Judgments are announced against Zedekiah and Jehoiakim, as well as against false prophets, unfaithful shepherds, and faithless priests (21:1–23:2; 23:9-40; 27:1–28:17)

Jehovah foretells humiliating defeats of many nations, including the Babylonians (46:1–51:64)

He also announces that Jehovah will conclude a new covenant with his people (31:27-40)

At Jehovah’s direction, Jeremiah buys a field in order to illustrate the certainty that Israel will return from exile (32:1-44)

He assures the Rechabites that they will survive, because they obeyed their forefather Jehonadab; their obedience shows up Israel’s disobedience to Jehovah (35:1-19)

He reproves Baruch and strengthens him with the assurance of surviving the coming calamity (45:1-5)

Jeremiah suffers because of his bold prophesying

He is struck and placed in the stocks overnight (20:1-18)

A plot is hatched to kill him for proclaiming the destruction of Jerusalem, but the princes deliver him (26:1-24)

The king burns Jeremiah’s scroll; Jeremiah is falsely accused of deserting to the Babylonians and is arrested and confined (36:1–37:21)

Finally, he is put into a miry cistern to die; Ebed-melech rescues him and is promised protection during the coming destruction of Jerusalem (38:1-28; 39:15-18)

Events from the fall of Jerusalem until the flight into Egypt

Jerusalem falls; King Zedekiah is captured, his sons are slain, and he is blinded and taken to Babylon (52:1-11)

The temple and great houses of Jerusalem are burned, and most of the people are led off into exile (39:1-14; 52:12-34)

Gedaliah is appointed governor over the few Israelites remaining, but he is assassinated (40:1–41:9)

Research by Dembski and Marks Makes Inroads in Technical Literature

Casey Luskin July 29, 2015 1:19 PM



Intelligent design is making unmistakable progress in mainstream scientific thinking. Here's an example from a new paper in the journal of Soft Computing, "Heuristic algorithm based on molecules optimizing their geometry in a crystal to solve the problem of integer factorization." It cites the work of leading ID researchers William Dembski and Robert Marks of the Evolutionary Informatics Laboratory -- quite favorably so, not in order to critique them.

The paper discusses integer factorization, or how we determine what prime numbers can be multiplied to yield another particular integer. This is essentially a search problem with applications in cryptography and other computer science questions. As the article explains:

Because of the computational intractability in factoring large semi-prime numbers, it is often used in public-key cryptography (PKC) such as RSA cryptosystems used in digital signatures, communication and e-commerce.
This is a very difficult problem but some algorithms have been developed to solve it. Which search algorithms are more efficient than others at solving the search? That is the precise question that Dembski and Marks set out to answer. The paper continues:
To quantify the quality of an objective function, we analyze our objective functions based on conservation of information in search theory (Dembski and Marks 2009).
Dembski and Marks have developed a principle called the "conservation of information" which says that if an algorithm does better than blind search, that is because it was given prior information, where the amount of prior information equals at least the measure of how far the algorithm outperforms blind search. Searches can thus perform better than a random search when they are fed information (called "Active Information") to help find the target. According to their methodology, Exogenous Information (I‡) represents the difficulty of a search in finding its target with no prior information about the target's location. Active Information (I+) is the amount of information smuggled in by intelligence to aid the search algorithm in finding its target. Endogenous Information (Is) then measures the difficulty the search will have in finding its target after the addition of Active Information. Thus, I+ = I‡ - Is.
After discussing various methods of solving the problem of integer factorization, the new paper in Soft Computing asks how the methods compare. They authors write:

In this section, we analyze our objective function based on conservation of information in search (Dembski and Marks 2009). We know that exactly two integers will exist, those are the prime factors of the semi-prime under consideration. Therefore for a semi-prime number, N, the probability of finding the two factors using a random search is

eq9.jpg (9)

Therefore, the endogenous information (Dembski and Marks 2009) measure is:
IΩ = -log p = 2 log N. (10)

Now, to measure the exogenous information (Dembski and Marks 2009), we need to know the problem-specific structure that the search algorithm takes into account. For example, if we just evolve one single factor using the objective function as defined in Eq. (3), then the probability of finding that factor is

q = 1/N (11)

Hence, the exogenous information measure (Dembski and Marks 2009) will be

Is = −log q = log N. (12)

Therefore, the active information measure (Dembski and Marks 2009) for this will be

I+ = log N (13).

After discussing how this methodology relates to solving a search question, they conclude, "The conservation of information in search provides a way to quantify the quality of an objective function."
What does all this have to do with Darwinian evolution? The research by Dembksi and Marks is applicable to essentially any search function. While this paper focuses on solving the problem of searching for prime numbers that can be multiplied to yield a given integer, Darwinian evolution is, at its heart, also a search algorithm. It uses a trial-and-error process of random mutation and unguided natural selection to find genotypes (i.e., DNA sequences) that lead to phenotypes (i.e., biomolecules and body plans) characterized by high fitness (i.e., fostering survival and reproduction).

Dembski and Marks explain that unless you start off with some information indicating where peaks in a fitness landscape may lie, any search -- including a Darwinian one -- is on average no better than a random search.

In some cases, even a random search can work when you have lots of probabilistic resources (i.e., time and opportunities for computation) or when there are lots of targets out there waiting to be found. Thus, Darwinian evolution can work when only one mutation is needed to give some advantage and when evolution takes place within a large, rapidly reproducing population (like we often see in bacteria).


But when targets are rare and there aren't lots of opportunities for the search (e.g., trying to evolve a complex multimutation feature in long-lived organisms like humans with small effective breeding populations), then such a random search won't work. The paper under discussion here doesn't get into any of that. It does, however, show the utility of Dembski and Marks's ideas in testing the efficiency of a search function -- an extremely important question in the context of evaluating Darwinian evolution.

Darwinism vs. The real world. V

Cardiovascular Function: What Happens When Real Numbers Are Wrong?

Howard Glicksman July 31, 2015 1:57 PM

Editor's note: Physicians have a special place among the thinkers who have elaborated the argument for intelligent design. Perhaps that's because, more than evolutionary biologists, they are familiar with the challenges of maintaining a functioning complex system, the human body. With that in mind, Evolution News & Views is delighted to present this series, "The Designed Body." Dr. Glicksman practices palliative medicine for a hospice organization.

Due to the laws of nature, the body must have enough energy for its trillions of cells to work properly. The body won't function very well if its cells don't have enough oxygen (O₂).

Evolutionary biologists claim that the organs described so far in this series, and the systems that control them, must have come about by chance and the laws of nature alone. But their theory seems to account only for how life looks and not how it actually works to stay alive under the laws of nature. Experience teaches that real numbers have real consequences when it comes to life and death.

Based on what we know about how the body actually works, our earliest ancestors had to be able to provide at least 3,500 mL/min of O₂, mainly to their muscles and heart, to be able to run fast enough and fight hard enough to win the battle for survival. That would have required their lungs to have a rapid enough airflow, a large enough volume, and an efficient enough gas exchange to bring in enough O₂. It would also have required that they have enough iron to make enough hemoglobin to be able to carry enough O₂ in the blood. And finally, their cardiac output (CO) needed to be at least 25 L/min to sustain the kind of activity levels needed to hunt rather than be hunted.

As I've noted in previous articles, lung function, hemoglobin production, and cardiac output are controlled by irreducibly complex systems, each consisting of sensors, integrators, and effectors that must also inherently know what is needed for survival. I call this natural survival capacity, because the systems involved must naturally have the capacity to keep a specific chemical or physical parameter within a certain range to allow for survival. We have looked at what happens to the body when its lung function and hemoglobin production do not measure up to what is needed. Now we will start to look at what happens when cardiac function is not up to snuff.

At rest the average male needs about 250 mL/min of O₂ to keep all of his organs working properly, and any increase in activity requires more. Walking slowly requires 500 mL/min of O₂; walking quickly, 1,000 mL/min; moderate jogging, 2,000 mL/min; and fast running, 3,500 mL/min of O₂. Since we know that the CO has to be at least 25 L/min for maximum activity, we can figure out what the minimum CO levels would have to be for lesser activity levels. We can do this by multiplying 25 L/min by the ratio of the lower and maximum O₂ consumption. So to jog at a moderate pace, the minimum CO would have to be 25 x 2,000/3500 = 14.3 L/min. To walk quickly would take at least a CO of 7.2 L/min, to walk slowly a CO of 3.6 L/min, and to stay at rest would need a CO of 1.8 L/min.

It is important to note here that these are real numbers that reflect real life and the laws of nature. No matter what evolutionary biologists say about how matter must have organized itself into the complex systems we know are needed for life, medical science tells you that if you don't have a CO of 7.2 L/min, you can't walk very quickly, if you don't have a CO of 3.6 L/min, it would be very difficult for you to walk even slowly, and if you don't have a CO of at least 1.8 L/min, you are probably dead. Certain parameters of cardiac function had to be met for our ancestors to survive within the laws of nature, and no expenditure of imaginary effort can deny this fact.

When real numbers lead to chronic debility with respect to the lungs, they usually involve problems with ventilation and/or gas exchange. But when dealing with chronic debility and the heart, we usually encounter four different problems. Each condition, individually, is capable of causing significant debility but, in real life, they often occur in combination. Just as adding a gas exchange problem to a ventilation problem can more quickly lead to worsening debility from pulmonary dysfunction, so too a combination of more than one of these cardiac conditions can quickly lead to significant weakness and a limited ability to be active and manage independently.

The commonest heart condition in developed countries, and what most people think of when they hear someone has heart trouble, is coronary artery disease. Even though the heart pumps blood throughout the body, it must also supply adequate blood flow to itself so it can do its job. As the blood flows out of the left ventricle through the aortic valve, the coronary arteries turn back over the surface of the heart. The heart is the hardest working muscle in the body and when its blood supply is compromised this can lead to significant debility and even death.

Another common cardiac condition is valvular heart disease. The "V" shaped one-way valves between the atria and the ventricles and the ventricles and their outflow tracts are structured in a way that allows them, when open, to facilitate the forward movement of blood, and when closed, to prevent blood from going backward. The efficiency of cardiac function is dependent not only on adequate coronary blood flow, but also on properly working valves. A valve can't be too tight, slowing forward blood flow, or too lax, allowing backward flow.

When the heart cannot meet the metabolic needs of the body it is said to be in heart failure. This third common cardiac condition can involve either the left or the right side of the heart alone, or both at the same time. In addition, left ventricular failure can be systolic, where reduced muscle contractility leads to weaker pumping action, and/or diastolic, where increased muscle stiffness reduces relaxation and the filling of the ventricle with blood. Both coronary artery and valvular heart disease are common causes of heart failure.

The fourth common cardiac condition is the cardiac arrhythmias. It is the sino-atrial node, the natural pacemaker in the right atrium that dominates the other excitable cells in the heart. It controls the heart rate and starts coordinated atrial contraction and the conducting system makes sure that coordinated ventricular contraction takes place soon afterward. Any disruption or short-circuiting of this signal formation, impulse conduction or coordinated muscle contraction can lead to significant debility and even death. All three of the conditions mentioned above, and other disorders, can predispose the heart to cardiac arrhythmias.

When real numbers lead to functional problems of the heart, these are usually the four main conditions that contribute to the situation. In the next few articles we will take a closer look at each of them.
