Dying For Sex

Competition drives marsupial males to suicidal sex - life - 07 October 2013 - New Scientist

I thought I'd share this as a beautiful example of how genes build bodies for the sole purpose of replicating themselves - not that they have any choice in the matter because everything flows from the simple fact that whatever characteristic, whether it's body form, metabolism, ability or behaviour, produces the most descendants in that particular environment, leaves the most descendents.

The marsupial mouse, Antechinus stuartii, also known as the brown antechinus, is not a mouse; it's closer to the kangaroos and koalas than it is to the mice and is an example of convergent evolution where species living a similar lifestyle in a similar environment tend to evolve superficially similar bodies, however, that's not the point here.

Male marsupial mice expend so much time and energy on sex during a very short breeding season that they die at the end of it due to immune system collapse caused by very high stress hormone levels. Breeding occurs only once a year probably due to females needing their insect prey species to be at a peak when they breed. Unlike small placental mammals which can rear several lots of young in a single year, marsupials are much slower breeders as the young are born very under-developed and take longer to achieve independence, so, to be able to breed successfully, females need to concentrate all their efforts on this single batch, which in turn restricts the males to very limited opportunities to breed.

This is how the authors of the original paper put it:
Abstract
Suicidal reproduction (semelparity) has evolved in only four genera of mammals. In these insectivorous marsupials, all males die after mating, when failure of the corticosteroid feedback mechanism elevates stress hormone levels during the mating season and causes lethal immune system collapse (die-off). We quantitatively test and resolve the evolutionary causes of this surprising and extreme life history strategy. We show that as marsupial predators in Australia, South America, and Papua New Guinea diversified into higher latitudes, seasonal predictability in abundance of their arthropod prey increased in multiple habitats. More-predictable prey peaks were associated with shorter annual breeding seasons, consistent with the suggestion that females accrue fitness benefits by timing peak energy demands of reproduction to coincide with maximum food abundance. We demonstrate that short mating seasons intensified reproductive competition between males, increasing male energy investment in copulations and reducing male postmating survival. However, predictability of annual prey cycles alone does not explain suicidal reproduction, because unlike insect abundance, peak ovulation dates in semelparous species are often synchronized to the day among years, triggered by a species-specific rate of change of photoperiod. Among species with low postmating male survival, we show that those with suicidal reproduction have shorter mating seasons and larger testes relative to body size. This indicates that lethal effort is adaptive in males because females escalate sperm competition by further shortening and synchronizing the annual mating period and mating promiscuously. We conclude that precopulatory sexual selection by females favored the evolution of suicidal reproduction in mammals.

Just another example of why evolution is not driven by an intelligent, compassionate and all-loving designer having the best interests of his creation in mind, but by an unemotional, thoughtless and uncaring process which mimics selfishness. It is all about producing more copies of genes in the next generation. Any strategy which achieves that result is the one which is bound to be adopted because no-one and nothing has any say in what is just as inevitable a process as is planetary motion and chemical reactions.

Does Evolution Support Atheism?

Does the scientific fact of evolution support an atheistic view of the universe?

According to fundamentalist Christians in Kansas, USA, it does, as does the fact of the Big Bang. But rather than accepting these scientific facts and adjusting their beliefs, like intellectually honest people do, not only do these swivel-eyed wackos cling to their superstition but they are doing what religious people often do when nasty facts get in the way of their hidden agenda. They try to ban them.

Fearful that Kansas school children might turn out to have the honesty and integrity to base their views on facts rather than sticking to what they were brainwashed with as the unfortunate children of Christian fundamentalist parents, they have even gone running to court again to try to prevent children in public schools in Kansas being taught these troublesome scientific truths.

Although they lost a vote in the Kansas state board of education by 8-2 to prevent schools adopting the Next Generation Science Standards (NGSS) on the grounds that they teach the science of evolution and the Big Bang and not creationism, they have files a complaint with the United States District Court for the District of Kansas (COPE et al. v. Kansas State Board of Education et al.) which contends that the NGSS and the Framework for K-12 Science Education (on which the NGSS are based) "will have the effect of causing Kansas public schools to establish and endorse a non-theistic religious worldview ... in violation of the Establishment, Free Exercise, and Speech Clauses of the First Amendment, and the Equal Protection Clauses of the 14th Amendment".

Yes, you read that right - "non-theistic religious..."!

It seems they believe that if you link the word 'religion' or 'religious' to something, that makes it a religion.

The complaint alleges that the NGSS:
... seek to cause students to embrace a non-theistic Worldview ... by leading very young children to ask ultimate questions about the cause and nature of life and the universe ... and then using a variety of deceptive devices and methods that will lead them to answer the questions with only materialistic/atheistic explanations. ... The effect ... is to cause the students to ultimately 'know' and 'understand' that the student is not a design or a creation made for a purpose, but rather is just a 'natural object' that has emerged from the random interactions of matter, energy and the physical forces via unguided evolutionary processes which are the core tenets of Religious ('secular') Humanism.
So there we are. You have it on the authority of a bunch of Kansas Christian loons, who need to pad out their complaint to the court by including the names of all their unfortunate children in the list of litigants, that the scientific facts of evolution and the Big Bang support atheism and that learning about them will give their children a non-superstitious, rational and hence Humanistic view of themselves and the Universe.

At least we agree on something.

The main thrust of the litigants' case (now don't laugh!) is that atheism and evolution are "non-theistic religions" and therefore by teaching facts instead of mythology and superstition, schools are promoting a religion, in contravention of the Establishment Clause. Presumably they are hoping the judge and the defense counsel will be unaware of relevant previous case history. For example:

  • Crowley v. Smithsonian Institution (1980). Ruled that the Smithsonian's evolutionary displays do not "create a religion of secularism."
  • McLean v. Arkansas (1982). Judge commented, "it is clearly established in the case law, and perhaps also in common sense, that evolution is not a religion and that teaching evolution does not violate the Establishment Clause."
  • Peloza v. Capistrano School District (1994). Citing Edwards v. Aguillard (1987), "unequivocally that while the belief in a divine creator of the universe is a religious belief, the scientific theory that higher forms of life evolved from lower forms is not."
Is this the reason Twitter and other social media are spammed daily by religiots who insist, despite common sense, that atheism, evolution and science are religions? Is this the new slogan of the anti-science fundamentalist lobby, or have the Kansas loons simply swallowed the daft notion with their usual credulous naivety? If they can just get it established in US law that these subjects are religions, they can get teaching them banned under the Establishment Clause. The next thing to go for would be history, then geography - anything which might cause children to question the superstitions their unfortunate parents acquired from their parents as children. In fact, why not go the whole hog and ban education altogether on the basis that believing children should not be superstitious is a religious view.

I wonder how long it will be before people in these culturally backward parts of the world realise that you can't ban facts and accept that people who base their opinions on them don't need put their heads in the sand and pretend they aren't there. Nor do we need to abuse our children by preventing them learning facts about the Universe they live in incase they make up their own minds about how to live their lives.

Censorious Catholics

Continuing my theme of religion and the history of censorship, this blog deals specifically with the role of censorship in the Catholic Church and how it handles dissent in general - or did when it had the power before the forces of democracy got its autocratic abuses under control.

One might expect that an intellectually honest belief, confident in its reasoning and certain of its factual basis, would welcome questioning and disagreement, knowing that it will either win any debate or will have the good grace and honesty to admit defeat and adjust it's thinking accordingly. This is of course anathema to the Catholic hierarchy which knows full well that the 'faith' has no such basis and so must be maintained by bullying and abusing its power to silence dissent and disagreement and prevent questioning at all costs.

The main method for handling dissent was of course to define anything not in full accord with Papal dogma as a heresy, and therefore Satanic, for which the only penalty was excommunication and death by burning. This was relatively simple when the only real way to promulgate ideas was by word of mouth, or by hand-written tracts which had to be laboriously copied to be reproduced, making it very difficult to disseminate new ideas and then only to an educated intelligentsia who could actually read. New ideas could be quickly nipped in the bud and the offending 'heretic' could be easily identified and 'cauterised'.

The invention of the moveable type printing press in Germany in the mid fifteenth century presented the Papacy with a more serious problem, demanding a different, more drastic approach however. For the first time, ideas could be put into print, even anonymously, and mass-produced for a wide readership. Even the Bible could, horror of horrors, be translated into the common tongue to be read by ordinary people!

To make matters worse, the nation states that the Vatican used to control were becoming more and more independent and, although they too took fright at the thought of all this information getting into the wrong hands and set up controls of the press, their interests did not always coincide with those of the Vatican and in some cases were even hostile to it.

After the dissolution of the Index, when some people thought the printing and distribution of the work was permitted, people were reminded again in L'Osservatore Romano (15 June 1966) that, as was published in the Acta Apostolicae Sedis (1966), the Index retains its moral force despite its dissolution. A decision against distributing and recommending a work, which has not been condemned lightly, may be reversed, but only after profound changes that neutralize the harm which such a publication could bring forth among the ordinary faithful.

Cardinal Joseph Ratzinger, later Pope Benedict XVI, 31 January 1985, in a letter to Cardinal Giuseppe Siri.
This called for drastic action by a church not used to having its authority and especially its dogma questioned. The only solution was to ban and burn publications which didn't have the personal approval of the Pope and to frighten anyone who read them with the traditional threat of Hellfire. Not exactly the response of an Islamic cleric panic-stricken at the thought that someone might question the authenticity of the Qur'an or the authority of an Ayatollah, but not far removed from it.

To that end the Vatican drew up a list of banned publications called the Index Librorum Prohibitorum or List of Prohibited Books and it became a cardinal sin to read them or even discuss them. Often the entire body of work of a particular author was added to this list, which was assiduously maintained until 1946 when, due to the sheer volume of published works it proved impossible to maintain the list. The list was officially downgraded (not abolished) in 1966 when the vatican announced in its official newspaper, L'Osservatore Romano, that, while the Index maintained its moral force, in that it taught Christians to beware, as required by the natural law itself, of those writings that could endanger faith and morality, it no longer had the force of ecclesiastical positive law with the associated penalties. (Wikipedia - Index Librorum Prohibitorum)

A list of all works on the Index can be found here. You will be amazed at the books good Catholics were not allowed to read. Amongst the very many authors who found themselves on this list, often for seemingly political rather than religious or doctrinal reasons were:

Galileo before the Holy Office, Joseph-Nicolas Robert-Fleury
Johannes Kepler (for advocating heliocentrism), Jean-Paul Sartre, Simone de Beauvoir, Voltaire, Denis Diderot, Victor Hugo, Jean-Jacques Rousseau, André Gide, Immanuel Kant, David Hume, René Descartes, Francis Bacon, John Milton, John Locke, Galileo Galilei, Blaise Pascal, Hugo Grotius and Giordano Bruno. All of these are now considered major works of science and philosophy. Giordano Bruno, who was burned at the stake for heresy in Campo de' Fiori in Rome in 1600 is considered the founder of modern cosmology.

Notable by their absence from the Index are works by Charles Darwin and Karl Marx. Maybe no one in the Vatican fully grasped the significance of these books.

Had the Vatican's censorship succeeded in suppressing science and philosophy we might still believe Earth is the center of the Universe around which everything else revolves and that the only route to knowledge is by reading the Bible and the opinions of early medieval theologians who had reached the status of the semi-divine. Had we not managed to strip the Vatican of its powers it might still be executing anyone who said otherwise.

Ironically, the Index, rather than succeeding in banning the spread of ideas, now serves as a grotesque record of the Catholic Church's doggedly brutal attempt to prevent human progress in the fields of theology, ethics, philosophy and science and to hold us back in the Dark Ages where superstition and ignorance were more conducive to Papal authority and institutionalised abuse of power by Catholic clerics.

Not surprisingly, the first response of Pope John Paul II and his enforcer, Cardinal Joseph Ratzinger, to the growing number of allegations of Catholic clerical abuse of children since the 1980s, was to ban their publication and bully those who complained or who wouldn't cooperate and obey the code of omertà.

And not surprisingly, one of the first acts of the new Pope Francis, on taking over from Benedict XVI, was to tighten the rules regarding leaking of secret Vatican information or anything concerning the "fundamental interests" of the Holy See, or Church government. This followed quickly on him being handed a report by his predecessor detailing corruption and criminal activities inside the Vatican and, so it has been rumoured, details of a procurement ring for discretely supplying male prostitutes. Leaking now carries an eight-year prison sentence. It has been argued that this effectively prohibits any Vatican official or anyone under Catholic Holy Orders from informing the secular authorities of any wrong-doing by anyone under Holy Orders. It certainly covers disclosure of the financial irregularities, including money laundering and other criminal activities, of officials in the Vatican's bank.

Fortunately, the option of burning at the stake is no longer available to the Vatican.

That Natural Wow! Factor

The walk and jump of Equisetum spores

One of the things I get from reading about science is that little frisson of pleasure in finding out something new and being amazed at the sheer inventive ingenuity of nature and especially of the process of evolution.

You can quite understand why designers of things like modern aircraft wings use a genetic algorithm. The unintelligent, trial and error approach, free from preconceptions and fixed ideas about what something should look like or how it should work, often comes up with the the completely unexpected; the sort of solution to a problem an engineer sitting at a draughtboard would take several lifetimes to come up with.

To appreciate this fully it helps to know a little about a group of plants known as horsetails. Briefly, horsetails, sometimes called horsetail ferns, though they are not true ferns, are considered to be intermediate between the ferns and the flowering plants. Characteristically, they have a stem which looks in cross-section like a bundle of simple stems and have feature looking a little like the 'vascular bundles' of flowering plants. Like the ferns they reproduce through spores rather than the seeds of the flowering plants.

Like all plants, one of the challenges they face is in dispersing their spores or seeds. The last thing a spore or seed needs is to find itself germinating right next to its mother, who will have grabbed all the resources. The study of how flowering plants alone have overcome this challenge is a major branch of botany in itself. Apart from wind dispersal, the precise mechanism used by the horsetails to disperse their spores was unknown, until now. And it's in the method of dispersal of these spores where our little surprise is to be found.

They walk and jump.

Horsetail spores. Above - contracted; below - expanded.
Abstract
Equisetum plants (horsetails) reproduce by producing tiny spherical spores that are typically 50 µm in diameter. The spores have four elaters, which are flexible ribbon-like appendages that are initially wrapped around the main spore body and that deploy upon drying or fold back in humid air. If elaters are believed to help dispersal, the exact mechanism for spore motion remains unclear in the literature. In this manuscript, we present observations of the ‘walks’ and ‘jumps’ of Equisetum spores, which are novel types of spore locomotion mechanisms compared to the ones of other spores. Walks are driven by humidity cycles, each cycle inducing a small step in a random direction. The dispersal range from the walk is limited, but the walk provides key steps to either exit the sporangium or to reorient and refold. Jumps occur when the spores suddenly thrust themselves after being tightly folded. They result in a very efficient dispersal: even spores jumping from the ground can catch the wind again, whereas non-jumping spores stay on the ground. The understanding of these movements, which are solely driven by humidity variations, conveys biomimetic inspiration for a new class of self-propelled objects.


The secret to how these ribbon-like elaters work is in their two layers. One of these layers absorbs moisture out of the atmosphere more quickly than the other does, so they straighten out, or curl up, according to the prevailing humidity. This causes them to move around randomly. Sometimes they become stuck to the surface of the spore or tangled up, so a tension builds up which is suddenly released and the elater spread out causing the spore to jump. Given that the movement is random and there are more ways of moving away from the parent plant than towards it, the result of this random walking and jumping is dispersal.

And that's it.

The sort of unexpected yet functional mechanism which evolution can come up with and which probably hasn't been improved upon since the Paleozoic era when horsetails evolved, some 250 to 540 million years ago.

Religion at the Dawn of Civilisation

Hunter, gatherer… architect? Civilisation's true dawn - life - 03 October 2013 - New Scientist

This article by David Roberts in this week's New Scientist is interesting for a couple of reasons:
  • Firstly, it casts doubt on the standard model for the historical development of civilisation where it is assumed that the development of agriculture led to settled communities and the start of permanent buildings, settlements, towns, etc, and also that political organization came as a consequence of the need for these communities to be organised into something more than extended family groups with minimal division of labour.
  • Secondly, it throws a spotlight on how religious apologists, especially Bible literalists, handle this sort of information.

A team of archaeologists led by Steven Mithen of the University of Reading, Berkshire, UK, excavating a site in eastern Turkey at Wadi Faynan, specifically a hill named Göbekli Tepe, have discovered what may well be a site for religious ceremonies and ritual, complete with monuments and seating. The site itself looks as though it was deliberately buried at some point to give the Göbekli Tepe hill. It seems highly likely that the rituals practiced there may have been blood sacrifices of some sort, judging by the drainage channels running under the floor.

But what is really interesting here is that the site is 11,000 years old - which predates the earliest evidence of agriculture by some 3,000 years. So it looks as though pre-agrarian (presumably still hunter-gatherer) societies in the area may well have been both settled and organised. Organised because it requires organisation to build large, communal buildings and to have a religion requiring such a building for religious rituals.

Now, I can see religious apologists getting excited by the thought that organized religions may well have been part of the daily lives of even our earliest modern ancestors from before even farming was invented, and that they might have been the trigger for forming settled communities - around ceremonial sites, for example. But this thought is bound to set up some unpleasant cognitive dissonance in the minds of Bible-literalists as we shall see in a moment.

For anthropologists, the discovery merely raises some interesting questions about how a settled community - which implies organisation and division of labour - could sustain itself. It has always been assumed that agriculture produced a surplus of food, i.e., more food than those who produced it needed for themselves, so the surplus could go to those who performed other tasks, like making pots (for cooking and storage), building roads and buildings, governing, soldiery, full-time priests, etc, etc. But this discovery implies there was some sort of surplus from hunter-gathering - which implies a very fertile location - and that then raises the question of why agriculture was invented if food was plentiful enough.

Well, the answer to that might not be fully known yet but none of it is a bar to accepting that human society progressed from hunter-gathering, through agrarian to urban civilisation and that the discovery of agriculture played a major role in this process. It simply raises the possibility that, at least in that part of the world, building and urbanisation might have preceded agriculture because the local conditions allowed it to.

In fact, thinking about this, it makes sense that agriculture would begin in a settled community, especially if we accept that it came about almost accidentally as people discovered that seeds gathered locally, when accidentally dropped around the settlement could be harvested later with very little effort, and that some animals captured alive would breed and provide food which didn't need to be hunted. None of this could happen if the group wasn't settled in the first place. And none of it could happen if the group wasn't strong enough, and organised enough, to be able to defend its territory from other bands of hunter-gatherers and from animals.

So, although the precise details of this transition are thrown into question by this discovery, we can begin to formulate alternative hypotheses and develop new models for the growth and development of human civilisation and adjust the time-scale accordingly. New information might well cause us to rethink and reassess so we incorporate it, knowing that our new model is probably better than the old one which we can eventually discard as more knowledge is added to confirm or falsify our hypotheses.

That's how science works, why new information is never a threat and why science always progresses towards a more complete understanding.

So what about religious apologists and especially Bible literalists? How do they cope with this sort of information?

Well, when the excitement of the discovery that early civilisation might have been facilitated by religion and that early humans might have believed in gods has died down and they try to fit the rest of it into their existing model - which has the sanctity of religious dogma so can't be changed - all sorts of conflicts begin to arise.

First there is the problem with the date. Bible literalist 'know' that Earth is only 6000 years old and that it was effectively re-set about 4000 years ago, so a date in 9,000 BCE is out of the question. This fact has to be dismissed tout suite one way or another.

There are a few standard approaches here:
  • Ignore it altogether. It can't be right because it doesn't fit the 'known' facts.
  • Rubbish the science. The dating method must be wrong and/or the scientists are lying or part of a massive conspiracy. Or Satan planted the evidence.
  • God made it look that way to test our faith. He's tricky that way.

Whatever the method, the fact of the date is dismissed. The conclusion is sacred so facts have to be ignored, so lots of extraneous 'facts' have to be inserted and a straightforward, uncomplicated narrative has to be confused and hedged around with exceptions and unproven assertions to either make it fit or to dismiss it. The conclusion is sacred so the 'facts' must change.

Secondly there is the problem of whatever religion it was, it wasn't the one in the Bible so, although people at the dawn of civilisation may well have been religious, and it may well have been religions which 'caused' civilisation, it was the wrong one. As any Bible literalist will tell you, there is only one true religion - the Christian one - so all other religions are Satanic, by definition. This means Satan was behind the earliest civilisation.

Oops!

Need to rewind and re-think here.

So, I'll let any Bible literalist who had the courage to stay the course to this point tell me how they handle this one. The god of the Bible obviously would not allow human civilisation to be started by people with a Satanic religion so, disregarding the embarrassment over the date, why did the god of the Bible give a false religion to the founders of human civilisation and why did they forget they were all descended from Adam and Eve through Noah?

Or was it Satan who started human civilisation?

Portugal's Catholic Fascists

Continuing my study of Portuguese history prior to going to Lisbon at the end of this month, I was not at all surprised to discover the role of the Catholic Church in the establishment of the first European fascist dictatorship in Portugal in 1926.

I was not surprised because I was already aware of the role the Catholic Church played in Spain, Germany, Hungary and various Latin American right-wing dictatorships of the twentieth century and how it has almost invariably been on the side of anyone determined to restrict the rights of ordinary people and maintain conditions of superstitious ignorance, squalor and want for ordinary people.

But I didn't fully appreciate how close the Pope and his clerics were to the Portuguese fascists. In fact, the military coup of 1926, which put an end to the Portuguese First Republic established in 1910, was effectively a Catholic coup d'état. It was led by the odious and deeply repugnant António de Oliveira Salazar, a devout Catholic and college roommate of Manuel Gonçalves Cerejeira who later became Cardinal Patriarch of Lisbon. Salazar had himself been a Catholic seminarian before studying law.

The Constitution Salazar imposed on the Portuguese was closely based on two Papal encyclicals, Rerum Novarum (1891) and Quadragesimo Anno (1931).

In 1940, a Concordat governing Church-State relations was signed between Portugal and the Vatican. The Church was to be "separate" from the State but to enjoy a special position. The Concordat of 1940 reversed many of the anticlerical policies adopted during the First Republic, and the Catholic Church was given exclusive control over religious instruction in the public schools. Only Catholic clergy could serve as chaplains in the armed forces. Divorce, which had been legalized by the republic, was made illegal for those married in a Church service, but remained legal with respect to civil marriage. The Church was given formal "juridical personality," enabling it to incorporate and hold property.

Under Salazar, critics believe that Church and State in Portugal maintained a comfortable and mutually reinforcing relationship. While assisting the Church in many ways, however, Salazar insisted that it stay out of politics — unless it praised his regime. Dissent and criticism were forbidden; those clergy who stepped out of line — an occasional parish priest and once the Bishop of Porto — were silenced or forced to leave the country. The rest of the Roman Catholic Church hierarchy, led by Cardinal Manuel Gonçalves Cerejeira, a great friend and supporter of Salazar, remained silent on the issue.


Under the Salazar dictatorship Portugal's economy continued to lag behind the rest of Western Europe. Portugal was effectively a third-world economy. Portugal also continued to cling to its remaining African colonies, having lost its South American one (Brazil) in 1822 and Goa, liberated by India, in 1961. Africans were regarded as a lesser people, there to be colonised and exploited and not entitled to the fruits of their labour which was all for the white Portuguese.

During the dispute with the British when the white minority regime in Rhodesia led by Ian Smith unilaterally declared independence from Britain and tried to set up a South-African style apartheid system in Rhodesia (now Zimbabwe) Portugal had helped organise boycott-busting fuel supplies to Rhodesia through the Mozambique port of Beira. Portugal, apartheid South Africa and the British Conservative Party were about the only outside supporters of the white racists in Rhodesia.

As 'front-line' states, Portuguese Mozambique and Angola, which bordered South African-administered South-West Africa (now Namibia) had been solidly behind the racist South African apartheid regime - and all under the beatific and approving gaze of the Catholic Church in the form of Salazar's old college chum, Cardinal Cerejeira and the Pope.

The wars that ensued in the Portuguese colonies of Angola, Mozambique and Guinea were to have a major effect on Portugal's political development. In a curious twist of history, the African liberation forces led by educated intellectuals Agostinho Neto in Angola and Samora Machel in Mozambique civilised their colonial 'masters' by exposing the young Portuguese military officers sent to suppress them to political thinking they had been carefully insulated from in their native Portugal where 'politics' consisted of praising the very wonderful António de Oliveira Salazar and blaming everything on socialists and foreigners. Many of these officers became politically and class conscious for the first time and began asking questions about what they were doing in Africa, and more importantly, why Portugal was lagging behind the rest of Europe and why the people could have no say in their own futures.

Salazar had a severe stroke in 1968 and was succeeded by the equally odious Marcello José das Neves Alves Caetano. Unable to contemplate even the thought of giving independence to the 'lesser races' on whose labour what little wealth Portugal had depended, Caetano continued to pour money (up to 40 percent of GDP) and troops into increasingly hopeless African counter-revolutionary campaigns until, in 1974, a military coup led by the young enlightened army officers who had been politicised by the African revolutionaries, Caetano and his fascist regime were overthrown in the 'Carnation Revolution'.

In February 1974, Caetano determined to remove General António de Spínola in the face of increasing dissent by Spinola over the promotion of military officers and the direction of Portuguese colonial policy. At this point, several left-wing military officers who opposed the war formed a conspiracy — the Movimento das Forças Armadas (MFA, "Armed Forces Movement"), to overthrow the government by military coup. The MFA was headed by the majors Vitor Alves and Otelo Saraiva de Carvalho and captain Vasco Lourenço and joined by Salgueiro Maia. The movement was significantly aided by other officers in the Portuguese army who supported Spinola and democratic civil and military reform. Some observers have speculated that Costa Gomes actually led the revolution.

There were two secret signals in the military coup: first the airing (at 10:55 pm) by 'Emissores Associados de Lisboa' of the song E Depois do Adeus by Paulo de Carvalho, Portugal's entry in the 6 April 1974 Eurovision Song Contest, which alerted the rebel captains and soldiers to begin the coup. Next, on 25 April 1974 at 12:20 am, Rádio Renascença broadcast Grândola, Vila Morena, a song by Zeca Afonso, an influential folk and political musician-singer forbidden on Portuguese radio at the time. This was the signal that the MFA gave to take over strategic points of power in the country and "announced" that the revolution had started and nothing would stop it except "the possibility of a regime's repression".

Six hours later, the Caetano regime relented. Despite repeated appeals from the "captains of April" (of the MFA) on the radio warning the population to stay safe inside their homes, thousands of Portuguese took to the streets, mingling with the military insurgents and supporting them. One of the central points of those gathering was the Lisbon flower market, then richly stocked with carnations, which were in season. Some military insurgents would put these flowers in their gun-barrels, an image which was shown on television around the world. This would be the origin of the name of this "Carnation revolution". Although there were no mass demonstrations by the general population prior to the coup, spontaneous civilian involvement turned the military coup into an event with unexpected popular participation.

Caetano found refuge in the main Lisbon military police station at the Largo do Carmo. This building was surrounded by the MFA, which pressured him to cede power to General Spínola. Both Caetano (the prime minister) and Américo Tomás (the President) fled to Brazil. Caetano spent the rest of his life in Brazil, while Tomás returned to Portugal a few years later.

The revolution was closely watched from neighbouring Spain, where the government and opposition were planning for the succession of Francisco Franco, who died a year later, in 1975.


In a poignant echo of the revolutionary Maoist slogan that political power grows out of the barrel of a gun, Portuguese revolutionary political power grew from carnations in the barrels of guns. Only four people died in the Carnation Revolution, shot by secret police before they realised the game was up. The people had taken their country back.

Very quickly the Portuguese colonies were given independence, democratic elections were organised and Portugal joined most of the rest of Western Europe as a civilised, democratic country owned now by the Portuguese people and no longer by a small wealthy elite and a cabal of Catholic clerics doing everything and anything in their power to maintain their privilege and unelected, unaccountable power, in the Catholic tradition.

For neighbouring Spain too the writing was on the wall. Within a year, Spain's Catholic-backed fascist dictator, Franco was dead and soon a restored monarchy under Juan Carlos restored a democracy stolen from the Spanish people in 1936. In 1986 Portugal and Spain joined the European Union.

The brutal experiment in political Catholicism called fascism which began in Portugal and which was copied in Spain, Italy, Hungary and Germany where it cost tens of millions of young lives to extinguish, was effectively ended when Portuguese soldiers put red carnations symbolising socialism in their gun barrels and declared the Carnation Revolution.

Viva a democracia Português.

An Earthquake in Theology

Ruins of the Convento do Carmo, Lisbon, Portugal
Towards the end of this month we'll be going to Lisbon, Portugal, for a few days for no other reason than we've never been there before and we got a good deal on a hotel. We normally go to a European capital city in December for the atmosphere and the Christmas markets. We'll be a little early this year. Such is the joy of semi-retirement and all chicks having flown the nest.

Devoutly Catholic Lisbon was the site of a major disaster in 1755 when large areas of it, and the surrounding area and coastline of Portugal, were destroyed by a massive earthquake and tsunami which was to set up major shockwaves in European culture and philosophy which are still being felt today.

The earthquake struck on All Saints Day, a religious public holiday on November 1, at about 09:30 a.m. local time, as Africa moved a little further north on a journey which has pushed the Iberian Peninsula and Italy north, raising up the Pyrenees and the Alps, and the Chiltern Hills in southern England as a secondary ripple and caused the depression now filled with the Mediterranean.

The earthquake's strength has been estimated as 8.5 - 9.0 on the Richter scale with it's epicenter about 120 miles off shore. Morocco was also hit and suffered major damage. Eighty-five percent of Lisbon's buildings were destroyed, including the Lisbon Cathedral, all major churches, the largest hospital where hundreds of patients burned to death, the national archives including detailed records of voyages of exploration by Portuguese navigators such as Vaso da Gama, the royal palace, the 70,000 volume royal library, hundreds of works of art by Titian, Rubens, and Correggio and the Carmo Convent.

Survivors of the initial shock sought safety in the open and congregated around the dock on the Tagus River estuary where they saw the sea drain out of the bay revealing the remains of shipwrecks and lost cargo, only to have it engulf them 40 minutes later when it came roaring back again in the form of a 60 feet high tsunami travelling at the speed of a galloping horse. Two more waves followed. The tsunami radiating out across the Atlantic also devastated the coast of north-west Africa, the Azores, the Caribbean, parts of southern England and possibly even Greenland.

One consequence of the disaster was that King Joseph I became severely claustrophobic and refuse to live inside walls, moving his entire court to a huge complex of tents on a hill on the outskirts of Lisbon.

In Lisbon alone the death toll was put at between 10,000 and 100,000, with the true figure probably close to 50,000, many of them in church at the time and in a country noted for it's piety and support for the Catholic Church. The only area of Lisbon to survive to any extent was Alfama, the red light district.

The earthquake of 1755 was thus one of the deadliest earthquakes on record and the worst in recorded European history but its aftershock on European culture was also profound. It caused many people in the early days of the 'Age of Enlightenment' to ask some very fundamental questions about a Universe which had been assumed to be supervised by a benevolent god - the Christian God, naturally - where the answer to every question was "God did it!" How could a disaster on this scale, and with apparent indifference to the piety and 'godliness' of its victims, occur in the presence of a benevolent god?

Theologians, desperate to keep their power and privilege, did what they always do in such times and smugly announced that it was all the victims' fault and exactly what they deserved. God did it! They had obviously offended God in some way and he was merely showing his displeasure. Apparently he was displeased with children, the sick, nuns, whole congregations at prayer together with their priests, the pious and impious equally, but he saw fit to spare the prostitutes and their clients who had chosen to celebrate All Saints Day in acts of worship of a more Earthly kind. The message was clear - be even more obedient to the church and give even more money, or God'll get you too. Don't ask questions! It's for your own good!

François-Marie Arouet (Voltaire)
The Lisbon earthquake became a major counter to the belief that a benevolent god ensures that everything is for the best in the best of all possible worlds, as lampooned by Voltaire with his idiotically optimistic Doctor Pangloss in Candide. It also prompted a young Immanuel Kant to publish three texts on the possible cause of the Lisbon earthquake. He got the mechanism wrong but this was the first attempt to explain a phenomenon in natural rather than supernatural terms, and is regarded as the beginnings of German scientific geography and certainly the foundation of the science of seismology. The European intelligentsia had begun to think in terms of natural forces shaping the world, and the world as we now see it being the result of those natural forces rather than being created as is a few thousand years ago with a creator god only acting to change things as a result of human actions, be it sinning or praying.

And so the Lisbon earthquake and tsunami was a major spur, if not the main cause, of a change in basic European philosophy away from the theological towards the scientific and the rational, a move which led inexorably towards us questioning the very origins of life, the planet and the Universe, leading through Darwinism to the present increasing rejection of magic and magic creators as a grown up answer to basic questions of why the world is the way it is. From that day onwards no scientific investigation has ever concluded that a god did it. No gap has ever been examined by science and found to be occupied by a god.

The god of the gaps is now the sole preserve of theologians who have not adjusted their thinking and who still blame the victims of natural disasters and spell out the same message that they did in 1755 - do what we tell you and give us more money, or our invisible friend will get you - because it loves you.

Unintelligent Design

It's amazing how, when you have a modicum of understanding of evolution - and I like to flatter myself that I know a little about it - you can find examples of it in other areas of life, not just in biology.

While waiting for the powers that be at Twitter to get their act together and decide what to do about my @RosaResurrected account being suspended for reasons which they just don't seem to be able to put their finger on right now, I'm busying myself with a pass-time I've had for some ten years or so now. I'm a volunteer transcriber for the FreeBMD website. This charity aims to put the official indices (sorry spell-checker but I refuse to call them indexes) of English & Welsh births, marriages and death registrations on line in an easily searchable format for people who want to research their family tree. To date I've transcribed over 1.25 million entries though rather fewer in recent years than I once did.

It suddenly occurred to me how an aspect of it is an almost perfect analogy for a feature which can sometimes be hard for non-biologists to understand about evolution - how redundancy can be built in and retained and why inefficiency is not always eliminated.

Briefly, and without being too technical, the indices we transcribe are scans of alphabetical indices to the actual registrations of births, marriages and deaths, since the second half of 1837, giving enough information for people to obtain a copy of the birth, marriage or death certificate if they require one. The indices themselves can be use to confirm the dates and places of the events and, in later years, the mother's maiden surname, the age at death, or the spouse's surname without needing to buy the certificates from the UK Government's General Registration Office. This, together with census records, is often all a genealogist needs to build up a family tree.

The software most transcribers use is WinBMD, a brilliant piece, designed by software devoloper Ian Brooke and intended to make the transcription process as fast and as accurate as possible. To that end, when entering the forename, the numbers 1-9 on the keyboard are predefined with what were the nine most common forenames in England and Wales. This list is user-definable but comes with default settings along with several other background files.

The 'problem' is that this list was derived from transcriptions from around 1850-1880 which were some of the earliest indices we transcribed. Obviously the fashion for forenames changes over time and what were the most common in those days are not the most common ones in use when transcribing the 1967 indices for example.

But users like me are now used to the list and know that pressing '5' will enter the name 'James' or that '3' will enter 'Elizabeth', etc. We don't want the list to change because we would have to get used to a new one and would probably keep selecting the wrong one while we learned it. By repetitive usage of the software we have developed a set of reflexes so that when we see 'John' we hit '6' or when we see 'Mary' we press '7'. For other names we start typing then select from a drop-down list by number - a drop-down list we've built up over the years by adding 'new' names to it when we transcribe them for the first time.

To learn a new common names list, or even just to change it slightly by reordering it, would slow down the transcription process and introduce possible errors, so we are stuck with an increasingly illogical and inappropriate list which becomes more out of date as time goes on, yet the investment in effort and loss of productivity entailed in changing it is never a cost worth bearing.

Just so with evolving organisms where an intelligent designer would be able to scrap an increasingly inefficient design and start afresh with a new improved version, whereas Darwinian Evolution never has any mechanism for a radical redesign because any tendency to do so will always involve a loss of efficiency, so any carriers of these genes will be less successful, not more, and so will be eliminated. The process of Darwinian evolution is invariably upwards towards peaks in the evolutionary landscape but only in very rare and exceptional circumstances, such as genetic drift in a non-selective environment, is evolution ever to able to move a very small way down this fitness landscape.

This is exactly what we see with the mammalian eye where a redesign would result in a better eye yet any moves towards rearrangement would produce a loss of function and a complete reorganisation with a single mutation is simply not possible because of the way the eye develops in the embryo. Not a problem for an intelligent designer, who would not have made such a silly mistake in the first place anyway, but quite impossible for Darwinian Evolution.

We see a very similar problem with the mammalian recurrent laryngeal nerve where, even in the giraffe with it's long neck, the nerve takes a ludicrously long path to get from the brain to the larynx - via the thoracic cavity where it passed under one of the aortic arches before going back up the neck again. This path made sense in our remote fish ancestors with their short neck where the heart lies just a little below and behind the brain, but with evolution's small steps forward and the impossibility of going backwards, we've ended up with an unintelligent design because the overall change led to more descendants and the one small step at a time lengthening of the nerve never gave a disadvantage large enough to counter the overall improvements.

The extreme detour of this nerve (about 15 feet in the case of giraffes[16]) is cited as evidence of evolution. The nerve's route would have been direct in the fish-like ancestors of modern tetrapods, traveling from the brain, past the heart, to the gills (as it does in modern fish). Over the course of evolution, as the neck extended and the heart became lower in the body, the laryngeal nerve was caught on the wrong side of the heart. Natural selection gradually lengthened the nerve by tiny increments to accommodate, resulting in the circuitous route now observed.


This is how we can tell that life is not intelligently designed. It quite simply isn't what an intelligent designer would end up with.

I hasten to add that Ian Brooke's WinBMD design is far from unintelligent but even he can't avoid his designs being subject to the natural force of evolution and so accumulating some of the features of it such as the increasingly inefficient yet not easily redesigned 'commonest' names list.

Religion And The History of Censorship

The recent phenomenon of the mass blocking campaign on Twitter and the various attempts to shut down blogs and websites is just another manifestation of the fear of dissent and debate that has always gripped religions. It tells us a great deal about the honesty and integrity of those who promote religion and who are desperate to suppress criticism. It tells us they know they will lose the argument in a free and open debate. It tells us they know they are pushing a lie and that their greatest fear is that they will be rumbled. It tells us their agenda is not what they claim and that they are too ashamed to tell us what it is.

One might expect a belief founded on good, established and unarguable evidence and principles of logical deduction would be confident enough in its methodology and basic philosophy to not only tolerate and allow dissent and argument but to positively welcome it, confident that it can win all arguments and dispel all doubts by good, honest argument and a dispassionate examination of evidence. One might also expect such a belief to be prepared to reassess, adapt and change whenever new evidence is found.

This, after all, is the proven methodology of scientific debate. No scientist worthy of the respect of his/her peers would present a paper to an audience of fellow scientists and then refuse to answer questions and demand that doubters be removed from the auditorium and even prohibited from practicing science. No scientist would publish a paper in a journal and demand the editor refuse to publish any papers which weren't in full agreement with it.

In fact, we would be fairly sure that seeking to suppress dissent and discourage discussion would betray a distinct lack of confidence. We might well suspect some low skulduggery or dishonest dealings; a deliberate attempt to mislead, probably in support of some secretive vested interest or in pursuit of a hidden agenda.

So, because all religions claim to know the truth with complete confidence, shouldn't we expect them all to welcome dissent and debate, confident that their beliefs are going to be strengthened by the ease with which doubt can be dispelled and misunderstandings or misinterpretations can be corrected?

Only if you are naive in the extreme.

Even the slightest contact with religion will show you that the last thing they will tolerate is doubt and disbelief. If you want to lose a religious friend, tell them you think their religion is wrong and another is right. Better still, tell them you think all religions are delusions and that only atheism makes any sense when the evidence, or lack of it, is examined objectively, honestly and dispassionately. Every atheist in the closet will tell you it's their religious friends' reactions they fear most.

No religion in the history of religion has ever tolerated dissent when it has had the power to prohibit it. They have all been keen on religious freedom when they were small minorities but that support is always inversely proportional to their strength in society. When they have gained absolute power, dissent is the first thing to be banned and no measure is considered too extreme to enforce it, as the long bloody history of religious persecutions, massacres and genocides shows. When the printing press was invented their first reaction was to control it and proscribe any printed matter which questioned religious dogma and especially religious authority and privilege.

Religious censorship is a form of censorship where freedom of expression is controlled or limited using religious authority or on the basis of the teachings of the religion. This form of censorship has a long history and is practiced in many societies and by many religions. Examples include the Edict of Compiègne, the Index Librorum Prohibitorum (list of prohibited books) and the condemnation of Salman Rushdie's novel The Satanic Verses by Iranian leader Ayatollah Ruhollah Khomeini.77


The antics of religious fundamentalists and creationist frauds on Twitter is the equivalent of shouting, "Shut up! Shut up! La la la la la! Can't hear you!". Like frightened rabbits caught in the glare of headlights they've panicked and resorted to the only method they know - suppression and censorship, imagining that questions go away and arguments are won by ignoring them. And in so doing they've drawn attention to themselves, to the dishonesty of their faith and and to their own awareness of its fraud and vacuosity.

They have shown the world they know their faith is a lie and is used as an excuse for attitudes and behaviour which would otherwise be unacceptable in a decent society not conditioned to think of piety as something to be admired and of faith as a virtue.

But don't treat these frightened little rabbits as a joke, laughable and pitiable though their antics might be and how cowardly and socially inept they might be as individuals. The real lesson here is what these inadequate little people would do to other people in real life if only they had the power. The great challenge of the growing atheist movement is to make sure that we will never ever make the mistake of finding out. As it is the worst they can do is to sit in their rooms cowering in fear at what the next unanswerable question might be, what challenge they will need to run away from next, how much longer a pretence of piety is going to work as an excuse, and fantasising about what they would like to do to the person who had the temerity to stand up to them.

It's better they stay that way and hopefully never realise that their behaviour on the Internet is probably the biggest single cause of the recent phenomenal growth in atheism.

Thanks For Your Support

Very many thanks to my many supporters on Twitter for your continuing support. It is very much appreciated and more than a little humbling. I see that some have offered to tweet links to my blog in my absence. This would be very much appreciated, as would posting links on other media such as Reddit and Facebook.

I'm hoping that Twitter will reinstate my @RosaResurrected account soon but given their refusal to with @RosaRubicondior one never knows. As with @RosaRubicondior, there is still no response from Twitter Safety to multiple requests for an explanation in terms of specific tweets and the rule(s) they breached, so I am left wondering what to avoid tweeting even if I am reinstated.

Is there anything specific or does their silence indicate that they don't have anything specific either, and have effectively handed over policing of Twitter to whicher cabal of extremists and control freaks can organise a mass censoring of opinions they don't want people reading? Spam-blocking may have originally been a means of reporting actual spamming but even a single original tweet can be reported as spam with no comeback on the person who is effectively filing a false report. Lies or genuine, it seems to make no different to the way Twitter handles it.

I suspect to avoid another suspension I would have to refrain from tweeting anything promoting atheism and anything critical of religion and creationism. I short, I would have to desist from exposing bigots, frauds and liars. I wonder it that's what Jack Dorsey had in mind when he set Twitter up.

One thing I am becoming convinced of is that the spam-block option on Twitter is their cowardly way out of bothering to police Twitter effectively - which would require staff, money and training. Spamming is quite simply not an abuse on the scale of threats of violence, lies, harassment, personal abuse, racism, sexism, child pornography, etc and can be handled just as effectively by blocking if a user does not want to see repeated tweets, advertising, etc.

On the other hand, spam-blocking, when used to trigger a suspension, puts another form of abuse in the hands of abusers to be used apparently with impunity - the unjustified suspension, and effective censoring of adverse opinion - which I would suggest is a far more serious form of abuse than spamming. Apparently when the 'secret' is known, by using spam-blocking at the right time, a user can be suspended almost instantaneously.

By contrast, I have now had outstanding for 8 days another explicit threats of actual violent to myself and my family from a Christian with nothing more that an automated acknowledgement. Recently it took Twitter 12 days to respond to a series of explicit death threat and then their action was a polite reminder to the abuser that threats are against the rules and please don't do it again. I say again: this was a response to a repeated death threat!

I also have outstanding complaints against a particularly obnoxious and probably clinically insane individual with a history of abusive tweets who currently has several accounts suspended, some for threats of sexually explicit violence against women. This has remained unanswered for 12 days following the standard acknowledgment.

All this make one call into question Twitter's handling of complaints when organised triggering of some algorithm can instantly auto-suspend an account without any checking, yet explicit death threats, threats of violence again a user's family and a continued campaign of harassment goes unchecked because it doesn't trigger an automated response and the few staff dealing with these complaints haven't gotten round to it yet, and can then only select a response from a pre-defined drop-down list.

Once again, thanks for your continued support, and thanks in advance for anything you can do to promote my blog and particularly the message it contains for truth, honesty, humanism and respect for all people.

I think it's time we organised a campaign to make Twitter more responsible in the way it handles abuse.

How Early Cells May Have Got Complex DNA

DNA-grabbing bacteria hint at early phase of evolution - life - 26 September 2013 - New Scientist

How did the simplest cells early in the evolution of life build their DNA?

It has always been assumed that DNA evolved by three separate processes:
  1. DNA transfer between living organisms.
  2. Sexual reproduction where DNA is shuffled with that of a partner to produce descendants with different combinations.
  3. Random mutation with natural selection sieving out the less fit mutations and favouring the more fit ones.

Now we can add a fourth: mopping up pieces of DNA from dead and decaying organisms and possibly viruses and incorporating them into the genome where they will be replicated in future generations.

DNA is notoriously stable as a molecule, which is why it can be recovered from long-dead bodies, dried up smears of body fluids and the partially fossilised remains of Neanderthals, mammoths and ancestral horses. Genetic material would have been more abundant in the environment in which early cells were evolving than in an adolescent boy's bedroom, especially since, prior to the evolution of photosynthesis, there would have been very low levels of free oxygen.

Søren Overballe-Petersen of the Natural History Museum of Denmark in Copenhagen found that when he fed fragments of DNA to a culture of Acinetobacter baylyi they were passively absorbed. They even absorbed fragments of 43,000 year-old mammoth DNA. The fact that this was a passive process suggests it may be a very primitive ability. By contrast, assimilating pieces of DNA passed across from another microorganism takes at least 40 genes.

So we have the possibility that very early cells acquired pieces of DNA from that sloshing about in their environment and that natural selection did the rest, sieving out those new combinations which were less successful at surviving to replicate and allowing through those which gave most descendants. With possibly billions of cells taking part in this process, it would have very quickly led to the accumulation of more and more complex and successful genomes. And of course the most successful organisms left more DNA fragments for others to mop up when they eventually died, so 'success' was not only inherited by descendants but could be picked up by the descendants of less successful organisms.

How Can You Tell A Creationist Is Lying?

Entelognathus (Image: Brian Choo)
Fish fossil suggests our skeleton evolved face first - life - 25 September 2013 - New Scientist

Obviously you can tell when a professional creationist, like those who are paid to lie by the Discovery Institute, are lying because their lips are moving. What I'm talking about are the bog-standard creationist such as those who swarm onto the Internet every day to try to convince people they know more than biologists do about biology, more than geologists do about geology and more than physicists and cosmologists do about physics and cosmology and who can even spell the odd word of more than two syllables.

One sure fire way to tell they are lying is not so much the patently ludicrous claims they implicitly make about their own expertise and qualifications in science but the way the things they claim are not supported by the real-world facts.

One such patently false claim is that there are no transitional fossils as is predicted by Darwin's and Wallace's theory of descent with modification, and so no evidence to support the idea that living species evolved and diversified over time from earlier common ancestors.

Manta rays. More primitive?
As the above article in this week's New Scientist shows, these are in fact common in the fossil record. One such is the recently-found Entelognathus, a fish clearly displaying transitional features showing how bony fish evolved from the extinct primitive common ancestor of the bony and cartilaginous fish known as the placoderms.

To the consternation of creationists, Entelognathus from 419 million years ago, found very well preserved in a quarry near Qujing, Yunnan, China, has a typical placoderm skull and body and the jaw of a typical bony fish almost identical to that found in modern bony fish - features which were later to evolve into the typical amphibian, reptilian, mammalian and avian jaws in the descendants of those bony fish which evolved into the terrestrial vertebrates.

The find also suggests that, contrary to popular opinion which has sharks and rays as the more primitive fish because they lack the bones of bony fish, having cartilage instead, they may be the more highly evolved in they they could have replaced bone with cartilage. As so often with science, an answered question simple poses some more unanswered ones, and so we progress.

Just another transition fossil for creationists to lie to us about as they wait forlornly for a single drop of evidence supporting their infantile notion to be found, whilst trying not to see the tsunami of evidence for Darwinian Evolution engulfing them.

Suspended Again

Sac O' Doughnuts
Yep! My Twitter account (@RosaResurrected)has been suspended again, and once again no specific reason has been given nor offending tweet identified.

And once again little Manuel de Dios Agosto is quite beside himself with delight and trying to claim the credit for it because he was once publicly humiliated by having to run away from a simple debate his infantile boasting had gotten him into, so exposing his claims of expertise in both science and theology to be fraudulent.

But before my followers understandably retaliate by filing complaints about him and his many accounts in an attempt to get him banned, think on what I said last time something like this happened.

Imagine what it would be like to have to live out your entire life fantasising and boasting about yourself on Twitter because your life is so meaningless and devoid of reason that you have no social life outside your room and the responses you can provoke on Twitter by being an unpleasant little abuser, liar and general nuisance. Your only claim to fame and your only sense of achievement came from conning a handful of credulous simpletons into believing that you were personally responsible for getting someones Twitter account suspended! And all this while desperately hoping no one makes public the reason you were expelled from seminary - the reason you have been ostracised and confined to your room by your community in the first place.

Do you really want to be responsible for depriving little Manny of the one thing he's achieved in life - being the reviled laughing stock of the Twitter #Atheist hashtag?

I'm not telling you what to do, merely asking you to consider the humanitarian aspect first.

A more effective remedy might be to get a campaign going to make Twitter adopt a fairer and consistent policy which is not open to the abuse of mass spam-blocking and in which offenders are given a specific reason for a suspension, including the offending tweet and the rule it contravenes, together with a right of appeal and review.

Religious Sneaks

Why is God suddenly so big in the schools we all pay for? Zoe Williams, The Guardian

This article by Zoe Williams (@zoesqwilliams) reveals how religions - for that read religious people - are using the underhand tactics of the sneak who has no regard to democracy and whose morals are those of the market place where the bottom line is all that matters, to force their religion onto the most vulnerable section of UK society - our children.

The degree to which this is driven not so much by a misguided humanitarian motive (to be charitable to them) but by the perceived need to maintain control of the people through established religion can be gauged by the way it is being actively facilitated and encouraged by the right-wing coalition government with its cabinet full of aristocratic multimillionaires and public school grandees.

As Zoe Williams points out:
..what we're watching is the steady takeover of provision by groups whose influence is the result of something other than majority support. A freedom of information request by the Guardian revealed that 25% of free schools were faith schools. The true figure is higher, since a free school can have a "faith ethos" without being declared a faith school. There is massive variation in how many non-faith pupils a school will take, and the processes are opaque.

<snip>

We are a largely secular country. Only a third of adults even approve of state funding for faith schools, over half actively disapprove, and no more than a quarter of parents would be happy to send their children to a faith school. Well, parents are pragmatic, and there is plenty of expedient religiosity, which then raises accusations about the sharp elbows of the middle classes – an attempt to blame individual parents for a dishonesty that is built into the system. – we are handing over to religious institutions the education of the children of people who don't believe in God.

<snip>

[Accord Coalition] research shows that where fair admissions are being compromised, and the school intake does not reflect the social profile of the area, faith schools are the worst – their ranks include 18 of the 20 least representative schools, and 70 of the top 100.

There are schools in that bottom 20 where only 6.3% of the pupils are on free school meals [a measure of social deprivation], against 48.7% in the local area. That area, incidentally, is Hammersmith and Fulham, which has a preponderance of highly selective faith schools. The disadvantaged kids there are being systematically concentrated into the remaining, non-faith schools. This is social apartheid – a paradox, given that church schools only sprung up in the first place to educate the children of the poor.


For those not familiar with the UK education system, the huge majority of children were educated until recently in schools run and regulated by the Education Departments of democratically-elected Local Authorities. Some of these were financed partly by Anglican and Catholic churches and Jewish communities as faith schools in which faith was a part of the daily life but the children were taught according to a national curriculum. A small number of children went to 'academies', which had started out as sixth-form colleges where children were prepared for A-level exams and then university. A small number, almost all the children of the rich, went to private schools confusingly and for historic reasons we needn't go into here, called Public Schools. A tiny number were educated at home under strict Local Authority supervision. It is a criminal offence in the UK to not send children to school or to provide them with an approved education between the ages of five and sixteen.

Michael Gove, Secretary of State for Education
Recently spent taxpayers' money to provide a new Bible
for every state school
The Coalition Government has now encouraged a vast expansion of the academies to cater for all ages and removed them entirely from Local Authority (i.e., democratic) control and placed them in the hands of boards of governors nominally accountable to parents but in practice, accountable only to themselves and their financiers. The plan appears to be to eventually take all schools away from Local Authorities and remove all democratic controls from them. The Tories seem to have noticed that it is invariably the wealthy middle classes who participate as school governors and who bother to turn up for meetings. In effect, the plan is to give control of education over to local Tories without them needing to bother with elections and all that democratic unpleasantness.

Some of the Christian groups are little more than chapters of American neo-con creationist Christian groups and cults. Needless to say, religious groups have seen this removal from democratic controls as a golden opportunity to get access to our children at their most susceptible and to indoctrinate them with the fear, superstitions and distrust of science and real-world evidence which will be used to control them later on as adults.

The British Humanist Association ran a partially successful campaign to force the Secretary for Education, Michael Gove, to ban the teaching of creationism, including it's pseudo-scientific under-cover version, intelligent (sic) design in faith schools, some of which had been actively advertising the fact that they intended to lie to children and tell them it was a valid scientific theory of the origin of life, so helping cast doubt in their minds about the validity of the scientific method and the integrity of the scientific community.

Eventually we managed to get assurances that teaching creationism in any form as as science would not be tolerated and that funding would be withdrawn from schools which did so. See I Have Mail. Seeing this as a bit wishy-washy with nothing to say how these schools would be monitored I asked my MP, Nichola Blackwood, MP (Oxford West & Abingdon) a right-wing Christian Tory who narrowly beat the Atheist Humanist, Dr Evan Harris in the 2010 General Election, to take up these concerns with the Department for Education. The email exchange can be read in I Have More Mail.

But it seems the systematic teaching of lies in pursuit of a religious agenda is not the only problem faith-based schools present and which even this right-wing government has been forced to control. They are now giving free reign to their class bias and creating poor, deprived ghetto schools as dumping-ground for the children of poor parents and those who are not dishonest enough to pretend to be religious and stump up donations to the local church, synagogue, mosque or temple. In short, they are creating social apartheid, and see nothing wrong with it.

One lesson from all this is that faith groups cannot be trusted when freed from democratic controls and jump at the chance to be undemocratic, unaccountable, prejudiced, selective and autocratic whenever the opportunity arises. In short, the temptation to be anything but decent humanitarians, even in the matter of educating our children, is too much for them to resist.

Faced with the haemorrhage of membership and drought in the income stream in recent years, religions have fallen back on their basic instinct for the dishonest tactics of the sneak and the parasite again.
