Section 44: Is elected local government office an “office of profit under the Crown”?

I also have doubts as to how an elected local government councillor could be an employee of the Crown, since he or she takes no instructions from the Crown and is not paid by the Crown.

Boilermaker Bill's Rum Hospital

The section 44 juggernaut just keeps rolling. The next question likely to come before the court as a consequence of Jacqui Lambie’s disqualification on dual citizenship grounds is whether her likely replacement, Devonport mayor, Steve Martin, is himself disqualified, for holding an “office of profit under the Crown”, with respect to his office in local government. Martin maintains that he is on solid ground, citing advice given by the then Clerk of the Senate ahead of the 2016 election.

Indeed, history suggests he has a strong case.

A Boy in Winter, by Rachel Seiffert

ANZ LitLovers LitBlog

Who should I thank for bringing this excellent book to my attention?  I know I read about it somewhere online, but I forgot to note down whose review it was…

I first read Rachel Seiffert when she was nominated for the Booker for her debut The Dark Room, a powerful trio of novellas that tackled the moral responsibility of ordinary Germans under the Third Reich.  Seiffert has continued to tackle confronting themes… Though I’m going to leave it for a little while before I read it,  I’ve just borrowed her next book Afterwards which explores the aftermath of service in the British Army in Northern Ireland and in Kenya.  I need a bit of space after reading A Boy in Winter, in which Seiffert returns to the topic of The Holocaust, this time, in a small village in Ukraine, beginning in November 1941 as the German Operation Barbarossa makes…

Mark Steyn on Problematic Speech and Free Speech.

American Elephants

Mark Steyn had a long legal battle with the Canadian Human Rights Commission nearly ten years ago about free speech, for the Canadian Human Rights Commission believes that free speech does not include words with which they disagree. They had the force of law behind them, and the descent into totalitarianism is not far behind.

It’s hard for some to realize that free speech actually includes words or statements with which you disagree, especially political words and thoughts. But if free speech means anything at all, you must defend speech that you don’t like. You may disagree, refute their arguments, prove that they are wrong, but they get to say what they believe. There are few things that are so damaging to American colleges and universities than attempting to create tiny spaces somewhere on campus that are “free speech zones.” There is nothing so offensive to those who are…

Here’s the organism (well, sort of. . . .)!

Why Evolution Is True

Did you guess what organism made the pattern below, found on a recent dive around the hydrothermal vents off Tonga?

Here’s the answer in the second tweet:

How big is that thing? The laser beam images are 10 cm (about 4 inches apart): The paper from which this comes (below) adds, “Note the shield-shaped elevation, marginal elevated rim and mote, and color (pale pink) of the area of the pattern compared with the surrounding veneer of gray calcareous lutite (image courtesy The Stephen Low Company).” You can find thousands of these things on the wall of the mid-Atlantic Ridge.

The pattern is similar to that described in a 2009 paper in Deep Sea Research (click on screenshot to go there):

World’s scientists turn to Asia and Australia to rewrite human history

The Conversation

Where did we humans come from?

Some 40 or so years ago, our origins seemed quite straight forward.

But now we see that the human story is far more complex. As summarised by Christopher Bae and colleagues in their latest paper just published in Science, data from Asia and Australia is becoming vital in piecing this new history together.

Zoom using +/- and click on each site to view more information. The box at top left can also be used to navigate through the evidence.

Read more: Curious Kids: Where did the first person come from?

The original story went something like this: modern humans (Homo sapiens) evolved to their current anatomical form in sub-Saharan Africa sometime after 200,000 years ago. They hung around for a bit, then groups started moving out of the homeland.

Arriving in Western Europe, a “human revolution” soon occurred (40,000 years ago), resulting in our much celebrated artistic and complex language abilities, a sort of creative explosion. These cognitively and technologically advanced peoples then out-competed the indigenous Neanderthals (and other archaic, or relatively ancient, human groups) and ultimately conquered the entire globe.

But fresh evidence has forced a rethink of this version of human history.

Modern humans

New analyses of human fossils have pushed back our earliest recognisable modern ancestors to around 310,000 years. And they weren’t found in eastern or southern Africa (like previous fossil finds), but from a site called Jebel Irhoud in Morocco. These findings have raised questions regarding exactly how – and where – we became “modern”.

Chimpanzees fish for algae using tools.

Traditionally, we saw the primary difference between humans and the rest of the animal kingdom as being the use of tools. However, primatologists and other biologists have been recording more and more instances of chimpanzees, orangutans, and other creatures making and using tools.

More than that, work initially in southern Africa has demonstrated that the creative explosion didn’t happen in Europe – it happened back in Africa, and far before the original 40,000 years ago date.

Currently, we understand that our complex cognitive and social capacities first began to emerge at around 100,000 years ago or earlier. And it wasn’t even an explosion, but probably more like a slow burn that slowly built into the raging fire of modern creativity.

New and old humans

Perhaps the most intriguing new evidence comes from the analysis of ancient DNA samples.

These studies are showing that interactions between the “new” humans (Modern Humans like you and me) and the “old” humans (Neanderthals, Denisovans, Homo erectus, Homo florensiensis, that are all now extinct) was not just a case of simple replacement. Instead, it appears that groups of new and old humans intermingled, interbred, fought, and interacted in a multitude of different ways which we are still disentangling.

Read more: Neanderthals didn’t give us red hair but they certainly changed the way we sleep

The results of these encounters appear to have left some lasting legacies, like the presence of between 1-4% Neanderthal DNA in non-African Modern Humans.

These studies are also beginning to identify some interesting cognitive differences between “us” and “them”, such as the fact that while we modern humans are susceptible to brain conditions like autism and schizophrenia, it appears Neanderthals were not.

The Asian story

The Australasian region is playing a larger and larger role in rewriting the stories of human history.

New fossils like Homo floresiensis have completely changed our view of what the human story is in this region. These tiny humans – “the hobbits” – found on the Indonesian island of Flores, continue to challenge palaeoanthropologists – are they a dwarfed Homo erectus? Or are they the descendants of something much more ancient? What are the implications?

But perhaps more interesting (to me at least), are the multitude of artefactual finds which have come to light in recent years.

It now seems that one of the species of older humans, Homo erectus, may have had some capability for symbolism – something rarely associated with them. This hypothesis comes thanks to new analyses of material from old excavations.

Looking back at material excavated from the first known locality of Homo erectus fossils – Trinil on Java, originally discovered by Eugène Dubois in 1891 – scientists stumbled upon a shell exhibiting a zig-zag pattern. This shape had been carefully inscribed using a stone tool more than 400,000 years ago (and perhaps as much as 500,000!). Such geometric motifs had previously been found at southern African sites – but all with Modern Humans – and all significantly younger. In Eurasia too, such designs are present, but rarely seen in Neanderthal contexts.

Other findings in Island South East Asia – this time associated with modern humans, Homo sapiens – are showing that the realm of extravagant creativity wasn’t the sole domain of Africa and Europe. New explorations and excavations on Sulawesi and Timor-Leste have recovered not only the oldest rock art in the world, but a vast array of jewellery and other artistic items.

Read more: Ice age art and ‘jewellery’ found in an Indonesian cave reveal an ancient symbolic culture

More than this propensity for art, it has also been found that the first modern human colonists in Asia were practising complex food-targeting strategies, like deep-sea fishing. Such a finding indicates an extensive knowledge of the sea, its dangers, and its rewards.

Focus on Australia

Australia too has been contributing to the rewriting of human histories.

In just the last two years alone, the date of original colonisation of this vast southern continent has been pushed back to around 65,000-years-ago.

The earliest bone ornament in the world, and the earliest ground-edge tool in the world were both found on this continent. It is becoming obvious that Australia was (and is) a land of highly adaptive and innovative people.

The speed at which new and astounding discoveries are being made in Australasia has effectively turned the focus of many human evolution researchers from the old bastions of Africa and Eurasia, much further east.

Recognising the growing importance of this region for furthering our understanding of our story, it is not only individuals that are moving their focus to Asia, but also whole departments. For example, the Australian Research Centre for Human Evolution based at Griffith University in Brisbane was launched with the expressed view of focusing on the Australasian region to answer evolutionary questions.

The ConversationIn all, it is an exciting time to be a researcher in this region. Indeed, it appears that the long sought after answers to some of the central questions in human evolution studies may finally be answered here.

Colonialism: Myths and Realities

The Classical Greeks colonised Sicily and what is now the western part of Turkey, so colonisation is not a recent European invention.

Notes On Liberty

My only claim to fame in regards to colonial scholarship rests on a paper I wrote for an Honors course in Western Civilization as an undergraduate. The paper won a spot at an Honors consortium held at Stanford, so I was able to do even more research on the subject. The following post is a summation of my research in blog form.

The first task I have is to explain what colonialism is not. Colonialism is not a European invention or concept designed specifically to keep non-white people down. The myth of the evil white colonialist is one of the most pernicious myths espoused today, and for a couple of big reasons. The first reason is that colonialism has been around for a long time. Today, the Han practice colonialism through the fascist Chinese state. In the 19th century, the Ashanti practiced colonialism throughout their slave-trading empire. The Ottoman…

“Purpose and Desire”: a misguided biology book that got a starred review on Kirkus

Why Evolution Is True

On November 7,  I called attention to a new book by biology professor J. Scott Turner, “Purpose and Desire: What Makes Something ‘Alive’ and Why Modern Darwinism Has Failed to Explain It,” and how the book got a starred Kirkus review despite its avowed intent to put teleology (goal-directed evolution) back into biology.  Turner works at the State University of New York’s College of Environmental Science and Forestry in Syracuse, New York, so he’s got biology cred. But he also admits he’s a Christian, the book’s production was funded by the Templeton Foundation, the book defends intelligent design pretty strongly at the end, and Purpose and Desire was endorsed on the Amazon page by Discovery Institute IDers Douglas Axe and Stephen Meyer.

I questioned the book’s credibility based on these summaries and a bit of other stuff I read, but since Turner beefed about my criticisms, saying I…

Why did slavery decline earlier in the North than in the South of the United States?

by Tim Harding

There were enormous differences in the timing of slavery abolition in the North of the United States compared to the South.  The gradual state by state emancipation of slaves began in the North soon after the Declaration of Independence in 1776.  Yet there was no legislated emancipation of any slaves in the South until 1865, after a bloody and destructive Civil War against the North.  Why was this so?  Was it simply due to geographic differences in the levels of racial prejudice against black Africans?  Or were there, as I intend to examine in this essay, more complex and relevant cultural, political, economic or religious differences between the North and the South?

In terms of the abolition of slavery, the dividing line between the North and the South was the Mason – Dixon Line, which separated free Pennsylvania from slave Maryland, Delaware, and what is now West Virginia.  This essay focusses on the internal North/South differences during the emancipation of slaves, rather than the abolition of the importation of slaves to America via the Atlantic slave trade, which affected both the North and the South.

During the British colonial period, African slaves were imported and distributed to all colonies to replace the dwindling supply of white indentured labour,[1] who were not arriving in sufficient quantities to replace those who had served their limited term.[2]  On the plantations, escape was easy for the white indentured labourer who could blend into the free population, but less easy for black Africans.[3]  In the North, slaves typically worked as house servants and labourers, including on farms and on maritime docks in loading and unloading ships.  Some slaves worked in various skilled trades, such as bakers, carpenters, blacksmiths and so on.[4]

Williams argues that the decisive factor was that the African slave was cheaper than indentured white servants.  The money that procured a white servant for ten years could buy an African slave for life.  He concludes that the primary reason for the use of African slaves was economic rather than racial; and that racial prejudice was a later rationalisation to justify economic facts.  Sugar, tobacco and cotton required large plantations and hordes of cheap labour.[5]  In America, these commodity crops were all grown in the South, as a result of climatic and topological differences from the North, where there were no such large plantations.  .

The first American plantation commodity crop was tobacco in the Chesapeake region, dating from the early 17th century.  Production of food crops – primarily maize – was usually limited to the requirements of self-sufficiency.  The switch from indentured labour to slave labour did raise productivity on the majority of plantations, just as the slave buyers had hoped.  Most of these efficient workers were Africans rather than Creoles, with slave women performing the same work as slave men.[6]

The American Revolution brought severe economic depression and social disruption to the Chesapeake region.  There were shortages of salt, medicine, shoes and cloth and slaves naturally suffered more than slave-owners.  Some slaves got to travel with their owners, where they learned what the Revolution was about, stimulating slave demands for consequential freedoms.[7]

Slaves picking cotton

Later on, after the invention of the cotton gin in 1793, the rapid expansion of the cotton industry in the South and Deep South reshaped American slave life.  The slave population in Alabama and Mississippi grew sixfold, mainly as a result of a substantial relocation of 700,000 slaves from the Southern border states.[8]   Strong world demand for cotton kept prices generally high, enabling the purchase and relocation of slaves from higher latitudes.[9]  Slaves were even bought from Northern slave-owners in anticipation of the abolition of slavery in those states;[10] although there was a market preference for experienced Southern slaves who were more efficient in the ‘sleight of picking cotton’.[11]  This evidence helps to show that slavery was clearly the cheapest and most productive source of labour in the South.[12]

African slaves were also of economic importance to the North.  Whilst there were no large agricultural plantations like those in the South, slaves performed menial tasks that whites would otherwise have had to do.  For this very reason, the Senate Foreign Relations Committee in 1828 objected to the colonisation of American slaves in Africa (which had been proposed as a solution to the perceived social problems that would arise from abolition).  The Senate Committee argued that colonisation would create a labor vacuum in the Eastern seaboard cities, increase the price of labor, and attract rural Africans and fugitive slaves to the urban centres.[13]

After the American War of Independence, there were several petitions by slaves to state legislatures begging for the abolition of slavery.[14][15]  These petitions largely fell on deaf ears at the time, although Vermont and Pennsylvania had already passed Acts for the gradual abolition of slavery in 1777 and 1780 respectively.[16]  All the other Northern states followed over the next decade or so, except for New Jersey in 1804.[17]  This gradualist approach is illustrated by the words of the key ‘Founding Father’ George Washington who in 1786 wrote:

‘I never mean (unless some particular circumstances should compel me to it) to possess another slave by purchase; it being among my first wishes to see some plan adopted by, which slavery in this Country may be abolished by slow, sure, & imperceptible degrees.’[18]

George Washington, as a farmer with his slaves

The gradual abolition of slavery in the Northern states at first freed children born to slave mothers, but required them to serve lengthy indentures to their mother’s masters.  As a result of this gradualist approach, New York did not fully free its last ex-slaves until 1827, Rhode Island in 1840, Pennsylvania in 1847, Connecticut in 1848, and New Hampshire and New Jersey in 1865.[19]

In stark contrast, none of the Southern states abolished slavery until after the American Civil War, when in 1865 the Thirteenth Amendment to the US Constitution of abolished slavery in all states, except as punishment for a crime.

The original Constitution of the United States included several provisions regarding slavery.  Section 9 of Article I forbade the Federal government from completely banning the importation of slaves before January 1, 1808; although some states individually passed laws against importing slaves.  Section 2 of Article IV prohibited states from freeing slaves who fled to them from another state, and required the return of chattel property to owners.[20]

In 1789, the Fifth Amendment to the Constitution, amongst other things, stated that no person (that is, a free citizen) shall be ‘deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation’.  Because slaves were property at this time, the Fifth Amendment was interpreted to mean that slavery could not be abolished without just compensation.[21]  The need to avoid expensive compensation payments may well have been the main reason why Northern governments opted for gradual abolition on an intergenerational basis.

Whilst racism was an obvious factor in the Atlantic slave trade,[22] there appears to be little evidence that racist attitudes towards Africans were more prevalent in the South than the North prior to the Civil War.  For instance, the minstrel shows in which white performers in black face disparaged and ridiculed Africans originated in New York.[23]  Most of these white minstrel performers were either born in New York or had lived in the city for long periods of their lives.[24]  Minstrel skits exaggerated racially distinctive features and behaviours to grotesque proportions.[25]  Together with newspaper cartoons and posters, Northerners were constantly reminding Africans of their alleged inferiority.  These racial stereotypes ‘hardly induced Northerners to accord this clownish race equal political and social rights’.[26]

Northern white workers protested often and bitterly against unfair competition from the far cheaper African slaves.  Founding Father John Adams observed that had slavery not been abolished in the North, the white labourers would have removed the African slaves by force.  In any case, white worker hostility towards the slaves had already rendered slavery unprofitable by lowering slave motivation and productivity.[27]

An alternative view is that the views of white workers held back emancipation in the North, through fears of labor competition from freed slaves.  White trade unions reinforced antipathy towards African labor competition.  They rejected racial unity as a way of achieving higher wages and vigorously opposed abolitionism.  To the trade unions, emancipation posed a serious threat of thousands of former slaves pouring into the North to undermine wages and working conditions.[28]  Although there were obviously conflicting views of white workers towards African slaves, they underscore the central importance of economics to the debate.

On the other hand, Litwick suggests the need to balance economic arguments for the North/South differences with consideration of cultural and ideological influences.  He suggests that political leadership was a factor in drawing attention to inconsistencies between the Enlightenment principles used to justify the American Revolution and the continuation of slavery.[29]  For instance, the Northern Founding Father John Jay (later Chief Justice of the Supreme Court) wrote:

‘To contend for liberty and to deny that blessing to others involves an inconsistency not to be excused.  Until America ridded herself of human bondage her prayers to Heaven for liberty will be impious’.[30]

John Jay (1745 – 1829)

Another cultural difference was that the leading antislavery religious movement, the Quakers, were much more active in the North than in the South.  Abolitionist sentiment in Pennsylvania, for example, resulted largely from early and persistent Quaker opposition to slavery as inconsistent with ‘the true spirit of Christianity’.  Following the lead of Pennsylvania, annual Quaker meetings in other Northern colonies adopted similar condemnations of slaveholding.[31]

In 1785, the New York Manumission Society, with John Jay as its president was also politically influential.  In 1799, John Jay as Governor of New York signed a bill providing for the gradual emancipation of New York State’s 21,000 slaves.[32]

As a counterbalance to these explanations, Davis argues that the Southern states also had antislavery political leadership from the likes of Washington, Jefferson, Madison, St. George Tucker, Patrick Henry, Arthur Lee and John Laurens.[33]  Yet there were no legislated moves towards the emancipation of Southern slaves, gradual or otherwise.  For example, the Virginian judge St. George Tucker despairingly wrote in 1795:

‘If, in Massachusetts, where the numbers are comparatively very small, this prejudice be discernable, how much stronger may it be imagined in this country, where every white man felt himself born to tyrannize, where the blacks were regarded as of no more importance than the brute cattle, where the laws rendered even venial offences criminal in them, where every species of degradation towards them was exercised on all occasions, and where even their lives were exposed to the ferocity of their masters;’[34]

This is not to say that there were no slavery abolition movements in the South – there were many, but they had little influence compared to those in the North.  According to Davis, in 1827 the number of antislavery organisations in the South outnumbered those in the North by at least four to one.[35]  Since 1794, Southern and Northern antislavery societies had met periodically as the ‘American Convention of Delegates from Abolition Societies’.  The number of states represented varied from year to year, but the consistent presence of the Pennsylvania and New York societies gave them a dominant voice.[36]

Slaves celebrating emancipation

The abolitionist sentiments in the South were vastly outweighed by the huge economic incentives to grow commodity crops such as tobacco and cotton at minimal labor costs.  Whilst there was some difference in the antislavery religious leadership of the Quakers in the North, there were insufficient differences in political leadership to account for the eighty year delay in Southern slave emancipation.  Nor is there sufficient evidence of differences in racial prejudice between the North and the South, at least until after the Civil War.

So we are left with a conclusion that the dominant differences between the North and South in terms of slavery abolition were economic ones.  On large Southern plantations where labor costs were crucial, African slaves were much cheaper than indentured white servants, not to mention free white workers.  There were no such plantations in the North, where white workers resented and agitated against unfair competition from African slave labour.  The emancipation of Northern slaves was most likely done gradually on an intergenerational basis to avoid governments having to pay compensation for the loss of slaves as property.

The fantastic eye of the scallop revealed in a new paper


Why Evolution Is True

Perhaps you didn’t realize, like reader Gregory (who sent me the Science paper), that scallops have eyes. But they do indeed—up to 200 tiny eyes lining the mantle, each a millimeter across: about the size of an “o” on a printed page.

Here’s what the array looks like in the scallop Pecten:

And a close up of the miniscule baby blue eyes:

Why do they need them? Because scallops aren’t sedentary molluscs: they swim actively by “jet propulsion,” flapping their shells to get away from predators or to find new resting sites. To wit:

It’s been known for a while that these eyes probably involve mirror reflection of incident light onto a retina, but how that reflection was achieved wasn’t clear, except that the mirror probably involved guanine crystals (guanine is one of…
