The 20th Century, 1914-1991, Good riddance

Even before I moved to this wonderful country, I used to read Philip Adams in the Australian; he was always the first bit of the paper that I turned to. As he got sourer and darker I pretty much stopped reading each column as soon as the word 'Howard' appeared, and I was pleased to notice a column of his not so long ago that reminded me of the old days.

How well I remember that feeling of growing up thinking you probably weren't going to grow up. I grew up in a city ringed by Titan II missile silos, at a school run by politically-aware leftist nuns.
That pervasive feeling that there is no future is why the 20th century embraced Cro-Magnon Metaphysics. If there is no future to worry about, why should anything but the present inform our moral judgments? Now we have learned to like living like this, and that is why, 'without skipping a beat', as Philip Adams puts it, we went from 'we'll all be nuked' to 'there's a hole in the sky', to 'the ice caps are melting' before getting to 'we need to establish a police state to safeguard our freedoms from the towel-heads'. Our society just needs something to panic about to maintain our culture of 'eat, drink, and be merry, for tommorrow we die.' Pathetic. That's what it is, pathetic.

Neolithic Metaphysics Revisited

Brent Howard, of Rydalmere, writes in El Pais de Murdoch:

David van Gend (Letters, 21/2) rails agaisnt the deliberate creation and killing of human embryos but offers no arguments. This process does not harm the embryos. Obviously, being created and then living, without consciousness, for a short period cannot be worse for an embryo than never existing at all. Even if we focus on embryos after their creation, they are not harmed by death. As eminent philosophers such as Michael Tooley and Derek Parfit have explained, unconscious embryos that have never had any desires or aspirations have no interest in ongoing life. The mere physical potential of the embryo does not impose any obligations upon others. We can uproot a sapling if we don’t want a tree, and John Howard’s potential to win another election doesn’t mean we must vote for him. We have no duties to embryos. Banning embryonic research that could help sick people is wrong.

If we have no duties to embryos- simply because all their capacity for suffering and joy, creation and destruction, lies in the future- than how can the potential existence of future generations impose any moral obligations on us?
It cannot. The particular comes before the general, and is the only reality. If the philosophers reject the moral obligation imposed by the embryo, which is actual in its potential, how much more must they reject the moral obligation imposed by those who are only potentially potential? It does not matter if we exhaust all fossil fuel resources: those future humans who might need them are only potential. It does not matter if we exterminate the last of the Surinamese swamp weasels. Their deaths are no more painful than their natural deaths would have been, and those future generations of swamp weasels were only potential: we have no duties to them.
These are only a few of the implications of the sophistry of those two philosophical gentleman. To reverence only the actual, and not the potential, is a religion for barbarians. It is appropriate for those who have no care for the past or the future, who are confident that each new day will bring a fresh hamlet to pillage to provide for all their needs. There is not only the moment. There is what a thing was, and what a thing will be, and these things should also inform our moral judgments.
One might argue: ‘Your fossil fuels, your Surinamese swamp weasels, those are things that are the common heritage of all humanity. I would not be so presumptuous as to judge that the rest of you should be deprived of their potential. But this embryo is mine, it belongs to me; its fate is mine to decide.’ This is a very old voice speaking. This is the voice of the Roman paterfamilias, with the acknowledged power of life and death over his children and his slaves.
But I say, no, that embryo is also part of the common heritage of all humanity. It does not belong to you, any more than the Surinamese swamp weasel belongs to the good burghers of Surinam. I will be diminished if I stand by while they clearfell the last stand of weasel swamp. I will be diminished if I stand by while that embryo is destroyed. I value it as a potential PhD student, as the potential drummer in the gurnge revival band responsible for the enigmatic concept album ‘Erklarungun der Kroten’, as the potential shopgirl who will smile- or scowl- at me at the checkout at Bi-Lo in 2025, even as the potential criminal whose wanton acts in a distant city will give me a momentary glow of Schadenfreude when I am a crusty old codger.
Destroying embryos that could grow up into any of those things, even if it could help sick people, is wrong.

La Muerte y la Brujula

So far, there have been no entries at all to the First Annual Accidental Blog Literary Competition, the goal of which was to rewrite any short story or poem by Jorge Luis Borges as if it had been composed by 'Chopper' Read... Surely 'Death and the Compass' ought to be easy.

The prize I had mentioned was a walk-on part as yourself in my upcoming Christmas Story about Giant Robots, 'A Christmas Story about Giant Robots', which I am going to finish in the next few weeks, so I am going to set a deadline for this feeble competition: the end of the year, or the end of human civilisation, whichever comes first.

Here is the beginning of 'A Christmas Story about Giant Robots':

If he had slept for just a few days longer, Dr Tamafearoa would have missed Christmas entirely. But the Dorado started waking its passengers on the day the colonists called December 18th, earlier than expected, and had finished by the 20th, and just after dawn on the 21st Dr Tamafearoa walked out onto the surface of a new world. All that he owned he carried in a little box in his right hand, except for his clothes, and the box itself- which was of ankylosaur shell inlaid with simestones- and two hundred thousand square kilometers of desert on the planet Lepidoptera which his aunt had left him. The sky was all peach and silver, like the new metal Dt Tamfearoa’s aunt had discovered, and the long shadow of Londonderry Tower stretched away in front of him, pointing to the Western Jungles. Long threads of cloud, the kind that had not been seen on Dr Tamafearoa’s world for a dozen generations, stretched across the bowl of the sky from one side to another.
‘That is where I will go,’ he said to himself, taking a deep breath of the humid air. He marveled at the smell of it, the honey and jasmine and ozone and faint drying bacon smell of this new world. He had always wanted to go to the Western Jungles. ‘I’ve always wanted to go to the Western Jungles,’ he said to himself, taking a little step forward like a child learning to walk. He had never said this to himself before, or even thought it, but he knew it was true. He took another step tentatively forward, unsure of how to deal with the traffic in the street. It was wide and clean, and lined with golden trees a hundred metres high, like any street anywhere, but the people! The people looked to Dr Tamafearoa like trees walking around. They wore clothes that looked like flowers, or clothes that were flowers, with a thousand things like leaves or petals that shimmered as they moved. They moved quickly, but did not go from place to place in the straightest way, and they spoke more loudly than Dr Tamafearoa was used to, and laughed more readily, and smelled the way people on Dr Tamfearoa’s world used to smell, before they were all deodourised.

A Parable from St. John, modified in the light of my rural experiences...

There was a man of the city who inherited an empty field from a distant relative, and resolved to be a good farmer. He bought the best seed he could from the seed-sellers, and had his servants sow it in his field, and manured and watered his field as he found it written that it should be done. But the wind scattered other seeds into his field, and others came on the feet of birds, or were lying sleeping in the soil for such watering and manuring as the man gave the field. So when the wheat sprouted and formed heads, many weeds also appeared.
The owner’s servants came to him and said, ‘Master, did you not sow the best seed in your field? Where then did the weeds come from?’
‘An enemy did this,’ he replied, thinking that some enemy of his had come in the night, and sowed bad seed among his good seed, for all his knowledge of farming had come out of books, and he did not know how the weeds had come into his field.
The servants asked him, ‘Do you want us to go and pull them up?’
‘No’, he answered, ‘ You are ignorant of farming, and while you are pulling the weeds, you may root up my good plants along with them. Let both grow together until the harvest. At that time I will tell the harvesters: First collect the weeds and tie them in bundles to be burned, then gather the wheat and bring it into my storehouse.’
But when the time of the harvest came, the field was only a wilderness of thorns and poisonous weeds. There was not one good plant in a thousand in the field, for wherever the good plants had grown they had been choked by the weeds. And the owner said to himself, ‘A thousand times more difficult it is now, to find the one good plant among so many bad, then it would have been to dig out the bad plants from the good at the beginning of the season. Now I must harvest all that grows in my field, and have it burned. For fear of losing some of my crop I have lost it all, and thinking myself a wise farmer I have proved myself foolish. In the next season I will not be foolish, but I will send out my servants to weed my field. True it is what the prophets say: whoever wishes to save what he has will lose it, while he who is willing to lose what he has will be rewarded many times over.’

Ecrasez l'infame!

I have slightly misread Prof. Holliday- his goal is not the advancement of science, but the downfall of religion, which he sees as the fountainhead of countless evils. Thus I stand somewhat in the same relation to him as a representative of 'Catholics for Choice' would stand to me, and he is probably right that there is not much point in us talking.

I fear he will be greatly disappointed should religion ever be effaced from the Earth. My observations lead me to predict that such a void will not be occupied by humanist scientific rationalism, but by New Age hokum, aimless hedonism, and endless re-runs of 'Survivor: Dinosaur Planet'.

I will accede to Prof Holliday's wish to have the last word:


#7:
At least we can agree about what Max Planck said. There is only one method of obtaining new information and that is by the scientific method, which a large number of people certainly do not realise.
However, in terms of social evolution, we have to add technology to science.

You wrote:

Secondly, if I did believe in a fundamental incompatibility between science and religion, I would keep it to myself. Claiming such a thing cannot do science any good.
There are vastly more people in the world with a religious world view than a scientific world view. In various parts of the world they are voters, legislators, or unelected rulers with power to determine science policy. They will not just go away. A great many of them do not need encouragement to think that science is godless and evil. What good can it do science to confirm them in their prejudices? About 30% of our first year students come from schools affiliated with religious institutions. Do I want to send their parents and teachers the message that science is fundamentally incompatible with their values? How would that help the long-term viability of science in Australia


Here we part company, because I could not disagree with you more. It is religions that are evil, not science. You only have to look around the world to see how much suffering is caused by religion: the ongoing conflict in the middle east. The ingrained hostility betweeen India and Pakistan, which has lead to three wars, and the even greater violence following partition. Years of conflict between catholics and protestants in Northern Ireland. And now the religious right in America, with its associated militarism. Almost all religions sanction war, and the killing of human beings. I have not the slightest respect for politicians and other members
of the establishment who regularly attend church and believe in the efficacy
of prayer.

Quite apart from all that, I think it is simply feeble to just follow a majority view. Would you believe that one should not have opposed the killing of supposed witches, because in the past the majority of people believed in their activities? Many people believe in astrology, would you therefore go along with that belief as well? Fortunately, human history is full of examples of a minority view triumphing over a mistaken majority. The abolition of slavery in the west is a very good example, or the abolition of child labour. With regard to the students you mention, it is not your job to send their parents any message about religion, but if students
enquire about religion and science, then I think they should be invited to participate in informed discussion.

I suggest we end our dialogue as it leads nowhere.

Regards, Robin Holliday

I told you that story so I could tell you this one...

Hey, did anyone hear about that wave of terrorist attacks disrupting the elections in Iraq? Me neither. It is a good day for us unreconstructed Neoconservative nation-building fanatics...

Anyway, I only put up that post about Prof Holliday’s article so I could put this one up:

#1:
Greetings Alex,

As you might possibly have expected, I wanted to make a few comments on Robin Holliday's article:

There is absolutely no place for a "vital force" or any non-material entity either in the egg, the sperm, the fertilised egg, the embryo, the child or the adult. Thus, there is no non-material soul, nor an afterlife.

Prof. Holliday is contrasting his professional understanding of biological processes with a very crude understanding of what a non-material soul might be. The Prophets did not have the same range of metaphors available that we do, and living today they probably would use different words. 'Consciousness' is not material in the sense that you can distill it out of something, yet it exists- it is apparently an emergent property, something arising from the interaction between material objects. Breath and Fire and the other historical analogies for consciousness validly refer to processes, not to static objects. An omniscient God existing outside of space-time would necessarily know all the details of the dynamic process of consciousness and be able to recreate it (upload it, in the language of Damien Broderick) to whatever 'hardware' it wanted to outside of space-time.
Thus the conclusion, there is no non-material soul, nor an afterlife, does not logically follow from Prof. Hollidays premises.

The next fundamental difference between science and religion is the issue of free will. In fact, most individuals believe in free will because it is a matter of common experience that they feel free to make their own decisions. For the religious, free will is God's gift to man. However, once it is accepted that we are complex organisms composed only of molecules, the completely new light is thrown on the supposed existence of free will. In making a simple choice, for example, between moving one's right or left arm, we feel completely free, but the fact remains that a signal is transmitted to the muscles that comes from the brain. The brain is not capable of spontaneously creating energy, because if it did it would contravene the law of conservation of energy, so the signal must come from somewhere else. Because we are conscious of feeling free, the signal must come from another part of the brain which is part of our unconscious brain function. Thus, there are forces at work of which we are not aware. These forces are determinants of our behaviour, and free will is no more than an illusion. Of course, some decision making is complex and may depend on knowledge, experience and external factors of which we are well aware, but this does not affect the basic conclusion that we do not have free will.

This argument betrays an ignorance of history. It is wrong to say that 'religion' supports free will and 'science' supports determinism: there are many atheistic scientists who believe in free will, often basing their arguments on woolly interpretations of quantum mechanics, and the argument between free will and determinism has been a constant feature *within* the main currents of religious thought for thousands of years. e.g.,: In their emphasis on the supremacy of God over all things, they [The Ahl al-Hadith] insisted that it was He alone who created human acts, even a persons evil acts. ... The Mutazilis, in their attempt to rationalise their faith, asserted the freedom of the human will which would be rewarded necessarily by Gods justice. The Hadith folk felt that this was to insult Gods power ... by ascribing to human beings alone their evil deeds, as if human creatures could create, like God, deeds or anything else.
(A 9th century controversy in the Islamic world, recounted by Marshall G. S. Hodgson in The Venture of Islam. In a more recent example, the Reformation in the Christian world was basically just a big argument about free will and determinism.)

The argument can be turned on its head, and I have argued elsewhere that a creator could easily include wheels or propellers in animal design. Yet no wheels or propellers exist in the animal kingdom. The Darwinian explanation for this is perfect: it is impossible to evolve a wheel by stages, because only a whole wheel has function.

I am sure that if a wheel was discovered in a living organism tomorrow Prof. Holliday would not accept it as a disproof of evolution- it certainly wouldnt be! So he shouldnt argue that the absence of wheels is proof. Wheels and propellors are forbidden by the physical difficulty of providing rotating structures with nutrients in organisms with the kind of biology that has evolved on Earth, not because they are non-functional in intermediate stages: otherwise, something like a wheel could equally well evolve with a non-locomotory function, being swapped over to a locomotory function later (viz., some of the models for the evolution of wings).

Experimental science has established itself as rational and reproducible, and there is no place for the contravention of natural laws, such as miracles, superstition and the occult. Finally, it is often pointed out that religious scientists exist. It seems that these are individuals who can in some way compartmentalise contradictory viewpoints, but this is an ability that I for one find extremely hard to understand.

Science is for examining the reproducible elements of the universe. It has been so good at explaining the observable features of the universe by considering only those elements that it is easy to assume that only those elements exist. That may well be true. But the existence of irreproducible, miraculous elements is not *disproved* by science. This phenomenon is not a miracle is an assumption you have to make *before* you can study a phenomenon by scientific methods. Saying that everything can be explained by science is not a scientific statement: it is a statement of faith. I think that everything within what we call the universe will end up being explicable by science, but I am fully aware that is just a leap of faith on my part.

Finally, I find *Prof. Hollidays* ability to compartmentalise contradictory viewpoints impressive. Surely he must act, in his day-to-day life, as though he has free will and is making real choices to pursue one line of research or buy one brand of soap powder over another? I couldnt do this. If I am to act as though I have free will, I need to hold to some philosophy that allows me to have free will!

Cheers,

[Dr Clam]

#2:
Thanks, [Dr Clam], and yap I was expecting comments from you.

First I'm sorry for being tardy in my reply, I've had to be away from
communications for a few days and just got back and logged in.

I shall pass your comments on to Robin together with your email address so
that he can replay to you directly.
And thanks for taking the time to state your viewpoint.

cheers,
alex

#3: To [Dr Clam]:

Alex Reisner has sent me your letter about my article. I think there
are some severe problems in communication language and logic.

I have read the following several times, without any comprehension:

Prof. Holliday is contrasting his professional understanding of biological
processes with a very crude understanding of what a 'non-material soul'
might be.


This seems to be the same as my saying "There are no fairies at the bottom of
my garden," and getting your response "You have a a very crude understanding of
fairies"

The Roman Catholic catechism includes the following:

Question: What is the soul?
Answer: The soul is a living being without a body, having reason
and free will.

That is very clear isn't it? It is a statement or dogma.

You should understand that I am merely presenting the views of
scientific rationalists, including Francis Crick (commonly regarded
as the greatest scientist of the 2nd half of the 20th century), Richard Dawkins,
and many, many others.

I find it extraordinary that a scientist could write the following:

I am sure that if a wheel was discovered in a living organism tomorrow
Prof. Holliday would not accept it as a disproof of evolution-


Thousands and thousands of animal species have been studied by
biologists over several centuries. As a scientist, what would
you make of someone saying "You might find a stone tomorrow that
does not fall to the ground"?
I do not think you are well versed in scientific methodology

There is a lot I could add about free will, but will not. You seem to adopt the
position of some philosophers who say that if you feel free, you are
free, therefore the issue is not of importance.
I did not mention determinism, which certainly is not a consequence
of a disbelief in free will. Stochastic events and chaos theory explain
that. The attempt by a few to use the uncertaincy principle of quantum
mechanics as a basis for free will does not stand up to any serious
scrutiny. We certainly know enough about neurones to be sure of
that.

Greetings Prof Holliday,

Thanks for writing back to me!

I have read the following several times, without any comprehension: "Prof. Holliday is contrasting his professional understanding of biological
processes with a very crude understanding of what a 'non-material soul'
might be."


It is the lines after that one that probably should be read several times, where I try to explain what I understand by 'non-material soul'.
If you say, 'I dissected Alex and did not find a sense of humour', then I would be right in saying, 'You have a very crude understanding of humour'.

This seems to be the same as my saying "There are no fairies at the bottom of
my garden," and getting your response "You have a a very crude understanding of
fairies"


My point is just this, which I will reiterate. In your statement "There is absolutely no place for a "vital force" or any non-material entity either in the egg, the sperm, the fertilised egg, the embryo, the child or the adult. Thus, there is no non-material soul, nor an afterlife," the conclusion does not follow from your premises. I am not seeking to defend the doctrine of the soul outlined in the Roman Catholic Catechism.

You should understand that I am merely presenting the views of
scientific rationalists, including Francis Crick (commonly regarded
as the greatest scientist of the 2nd half of the 20th century), Richard Dawkins,
and many, many others.


You have correctly identified undue respect for authority as my one great weakness, but appealing to authority rather than answering my objections is cheating! :)



I find it extraordinary that a scientist could write the following: "I am sure that if a wheel was discovered in a living organism tomorrow
Prof. Holliday would not accept it as a disproof of evolution"
Thousands and thousands of animal species have been studied by
biologists over several centuries. As a scientist, what would
you make of someone saying

Firstly, I didn't say something like, "You might find a stone tomorrow that does not fall to the ground", I said something like: "I am sure that if a stone was found tomorrow that did not fall to the ground you would not accept it as disproof of gravity." Neither would I. It would be some anti-rationalist's trick with magnets, I am sure.

But the two counter-factuals are completely different:

1) The gravitational interaction between pieces of matter is well described by laws that appear to apply always and everywhere in space-time, from extensive observations.

2) We have studied thousands and thousands of animal species, but all of them share a common ancestor and are restricted to a very small part of the universe. The properties of living organisms on Earth are *contingent on historical events* and quite different forms of life could have evolved elsewhere. It is physical limitations, based on the historical development of life on Earth, that prohibit wheels: it is possible to envision different biologies that do not have these physical limitations. It is not the absence of intermediate forms that prohibit wheels, because the intermediate forms could have had some other function and only swapped over to be wheels later.

There is a lot I could add about free will, but will not. You seem to adopt the
position of some philosophers who say that if you feel free, you are
free, therefore the issue is not of importance.
I did not mention determinism, which certainly is not a consequence
of a disbelief in free will. Stochastic events and chaos theory explain
that. The attempt by a few to use the uncertainty principle of quantum
mechanics as a basis for free will does not stand up to any serious
scrutiny. We certainly know enough about neurones to be sure of
that.


I certainly don't want to get into an argument about free will either- I had enough of that as an undergraduate to last me a lifetime! I regret putting in that line at the end about your ability to compartmentalise your ideas, it was a foolish non sequitur. Please accept my apologies.

My point was just that the equation religion=free will is fallacious, as historically most of the opponents of free will have been truly, madly, deeply, religious.

Best regards,

[Dr Clam]

#5: To [Dr Clam],

I do not think our correspondence is leading anywhere. I have
read your two Emails several times but I am unable to extract anything
about your real opinions on the topic of science and religion that I wrote
about.

One thing you seem to invoke is a non-material "consciousness." Now I
am aware that many have referred to and discussed the "problem"
of consciousness. To me the problem is that we simply do not yet understand
brain function, and I would add that many animals appear to have an
awareness of the world around them and therefore consciousness. I cannot
envisage any conceivable reason why consciousness is not part of sensory
perception and brain function. Brains consist largely of neurones, and
neurones are made up of molecules. What else can there be?

I will just add two further comments. You write:

Thus the conclusion, 'there is no non-material soul, nor an afterlife',
does not logically follow from Prof. Holliday's premises.


There are NO premises, but a mass of information from modern
biology.

On free will, you write:

This argument betrays an ignorance of history.

I take exception to this. I have been a student of the philosophy
and history of science and I think what I wrote about free will
has absolutely nothing to do with history. It is about conservation
of energy and neurone function.
I can also add that I am completely unconcerned about the choice
of soap powders. It could be arbitrary, or it could be that my wife or
someone else recommended one. The absence of free will is very
important when it come to judging anti-social behaviour. Most people
believe in retribution, ie punishment, for criminal acts. I do not, because
such acts are not the result of "free will." Deterrence, however, is very
important, in a variety of contexts. This is a hugely important social issue,
and I think most people are very confused about it
If you want to continue this, I suggest you summarise in succinct form
your own views about science, religion, vitalism, consciousness, or
whatever. Then at least I will know where you stand. At present your
real opinions are something of a mystery to me.
I will send you next week a few reprints on matters directly or indirectly
related to all these topics.

Regards, Robin Holliday

#6: Dear Prof Holliday,

You are probably right that this is useless, but I will have one more go and try to answer your questions. I hope I am right in believing that you published your piece on The Funneled Web because you want people to argue with you, and will not be offended by me. I certainly do not wish to cause any offence and am only interested in making my ideas clear. Evidently I have a long way to go!

You wrote an article claiming that there is a fundamental incompatibility between Science and Religion. I do not believe this is true. My first published letter to the editor was to the Catholic Leader when I was 19, telling people that they should not fear evolution, because it was fundamentally compatible with religion. I have continued to argue this with many people in many places over the last few decades, all of them people who fear and distrust science because of the sort of rationalist triumphalism embodied by people like Prof Dawkins.

My understanding of the scientific method is grounded in its practice and in the writings of the 19th century American Pragmatist Charles Sanders Peirce: once we know the consequences of a thing, we know all there is that can be known about it. I have a quote on my website by Max Planck that embodies the same principle: Experiments are the only means of knowledge at our disposal. Everything else is poetry, imagination. Those are statements I believe. I think they demand a greater degree of humility and agnosticism from practitioners of the historical sciences than we have seen from Prof Dawkins. Experiments cannot tell us whether miracles are possible, whether there is or is not a God or an afterlife, or what if anything exists outside space-time. We are free to chose our own poetry for whatever is not amenable to experiment, and we do not have any scientific grounds for preferring Housman over Manley Hopkins.
I should add that I am not currently a practising Catholic, and I do not believe in any kind of vital spirit. I believe what I attempted to explain in my first message, that the soul as some kind of spirit existing independently from the body is an unnecessary hypothesis. I am a theist in the Judaeo-Christian-Islamic tradition and strive to make my beliefs consistent with our observations of the universe.
I completely agree with you about animals. I do not believe there is anything uniquely important about human beings and have been a vegetarian since 1990 because of my respect for animal consciousness.
I wrote to you because I disagree strongly with the claim of your article. I do not believe there is a fundamental incompatibility between science and religion.

Secondly, if I did believe in a fundamental incompatibility between science and religion, I would keep it to myself. Claiming such a thing cannot do science any good.
There are vastly more people in the world with a religious world view than a scientific world view. In various parts of the world they are voters, legislators, or unelected rulers with power to determine science policy. They will not just go away. A great many of them do not need encouragement to think that science is godless and evil. What good can it do science to confirm them in their prejudices? About 30% of our first year students come from schools affiliated with religious institutions. Do I want to send their parents and teachers the message that science is fundamentally incompatible with their values? How would that help the long-term viability of science in Australia?

Thirdly, if I did believe both in a fundamental incompatibility between science and religion and that it was a good thing to point this out, the three main points I made in my first letter would hold true, and if I was an atheist I would probably still want to make them. There are flaws in your arguments that make them ineffective in demonstrating what you wish to demonstrate.

(1) The findings of modern biology have no bearing on whether there is something that, in its consequences, is indistinguishable from the soul of tradition. A premise is defined as a proposition which an argument is based on or from which a conclusion is drawn. You cannot have any logical argument without premises, and I am as convinced as you are that the facts of biology you cite are sound. But your conclusion does not follow from them. I tried to explain this but have failed completely to make myself understood. It would probably take a whole essay on its own, which I do not want to write, and I am sure you do not want to read!

(2) Your wheel argument is flawed. The lack of wheels is a contingent fact of terrestrial evolution, not a necesary characteristic of life everywhere, and a wheeled organism would not constitute disproof of evolution.

(3) It is wrong to state that belief in free will is a characteristic feature of religion. That is the only point I wanted to make. I have absolutely no interest in arguing about free will as such because I am convinced it is a futile exercise. I am sure you have an excellent understanding of the history and philosophy of science. But you would not say that belief in free will was a characteristic feature of religion if you had made any serious study of the history of religion. I am sure this is a topic that you have little sympathy or patience for, so this is understandable, but the history of religion is inextricably bound up with human history as a whole. The claim that belief in free will is a characteristic of religion in general is an untenable one.

I hope I have cleared up the mystery a little. I do not think my opinions are really of any relevance. I know I have no chance of convincing you that your thesis is wrong, or likely to cause harm to science, but hoped there was some worth in pointing out the flaws in some of your arguments. I would count it a victory if you became a more accomplished polemicist for your cause, because this can only be achieved by understanding your opposition, and the more there is understanding, the more there is hope.

All the best,

[Dr Clam]

I shall consider Prof Holliday's reprints at a later date...

On a scale of one to ten, it's not good

I think the recent events in the tsunami-prone fringes of Devil Bunny City are the most depressing things to have happened in this country while I have been here. If I, an educated middle-class Anglo-Slavic Catholic living hundreds of kilometers away, feel a sudden urge to tattoo 'Islam Power' on my knuckles, invest in a much larger car stereo, and beat the living daylights out of that idiot from Penrith who was stupid enough to give his name to reporters, I can only guess what my former neighbours are thinking.

As for Alan 'Inyenzi' Jones, surely those new sedition laws provide something he could be charged with? The role of talkback radio in the whole affair is frighteningly reminiscent of its role in the Rwandan genocide.

Censored

I will depart again from my habit of not saying anything about my real life, because of the interesting thing that happened today. I have been censored, for the first time since primary school.

(1) My university offers a Bachelor of Health Sciences (Homeopathic Medicine) degree.

(2) The students actually get taught real knowledge stuff by my university. It doesn’t teach the actual homeopathic medicine bit, but leaves that in the hands of a bunch of fruit loops.

(3) Homeopathic medicine is a load of toss. It is an order of magnitude less scientific than Creation Science, because Creation Science depends on some supernatural force kicking off the natural laws we know and love, and homeopathic medicine just tells said natural laws to bugger off.

I had a bit on an out of the way corner of my web site at work mentioning these three facts, in very slightly more polite language than I’ve given here, with links to our degree programme, the fruit loops, and a representative web site demonstrating that homeopathy is a load of toss.

Got a message from the Dean this afternoon, saying: ‘Please remove the references to homeopathy on your web site.’

Being at heart a forelock-tugging slave to authority, I said ‘okay’.
Having a tiny bit of pride, I replaced the blurb with ‘The links that used to be here have been removed by request of the Dean.’

About ten minutes later, I got another message from the Dean, saying: ‘Please remove the reference to me on your web site.’

So I wrote back, ‘Please rephrase your request as a directive and I will happily comply.’
And the Dean replied: ‘That was a directive, I was just being polite.’

So I did that. Then I went to ask someone who knew about Information Technology Legal stuff if the Dean was actually allowed to do that. And they said (I think) ‘Yes.’

So I spat the dummy and took my whole website down. Childish, I know...

Hmmm...

Here is a link to an opinion piece by Prof Robin Holliday, who has discovered all sorts of neat molecular biology stuff, entitled ‘The Fundamental Incompatibility Between Science and Religion’.

I am not entirely sure why he wrote it.

If science and religion were fundamentally incompatible, would it really do science any good to convince people of the fact?

There are vastly more people in the world committed to a religious world view than a scientific world view. Why split humanity into two camps, with yourself in the small embattled one, if you don’t have to?

I suppose it just reflects the spirit of the age: here are these people with feet in both camp ‘us’ and camp ‘them’ (f’rinstance, religious scientists, or moderate Muslims). Do we think of them as:

(i) Useful bridges to the other side, expressing a point of view that we need to understand if we are going to reach any long term solution, or

(ii) Dangerous and deluded fifth columnists who must be forced to conform to the ideals of camp ‘us’?

So that is what *really* bugs me about Prof Holliday’s article, when I think about it.

Walk Against Warming?

There are signs up around my workplace inviting people to walk/cycle to work on some particular day- not sure which one it is- as a token gesture to reduce CO2 emissions. I was thinking about whether this was sensible or not.

I live too far away to propel myself to work without spending 4 hours a day commuting, but I will assume for the purposes of argument that I live only 5 km away. I get around about 500 km for a 50 litre tank of petrol, so driving 10 km I would use a litre of petrol- about 750 g of stuff that gets converted into CO2 (2.3 kg) and water (1.1 kg).

Now, if I am going to walk or cycle to work indefinitely, and not just as a token gesture, I will need to increase my food intake, or I will waste away and die. My gee-whiz exercise bike says it takes about 250 kcal to bicycle 10 km. When I convert this into rice, it comes out at only 69 g that I convert into about 100 g of CO2 and 20g of water. So it looks pretty good!

But... My rice has been grown somewhere with diesel-powered tractors and fertilizers produced using fossil fuels, and irrigation water probably pumped with fossil-fuel derived energy. It is packaged in plastic bags made from fossil fuels by machines run on fossil fuels. Then, the somewhere it has been grown is a long way away. The closest somewhere is around Griffith, from which it has probably been carried in a diesel-fuel powered vehicle to a central depot in Sydney, and then carried here the same way. But the packet actually says it is from Thailand: so it has been trucked from somewhere in Thailand to somewhere else in Thailand, loaded onto a fossil-fuel-powered ship, and taken to Sydney first. How much does that all add up to? I have no idea. The internet factoids that purport to answer this sort of question are all from end-of-cheap-oil doom and gloom people who want to make things sound as bad as possible, but I did find some reasonable looking data from a Centre for Sustainable Systems at the University of Michigan estimating that in the United States 7.3 units of energy are consumed for every unit of food energy produced, on average. In another part of the same article they have some specific calculations for a tin of sweet corn (8.1:1) and grain-fed beef (36:1) and estimate ratios of about 5:1 for a vegetarian diet and 10:1 for an omnivorous one. They also calculate that on average, 1.8 units of food energy are produced for every unit consumed. Things here are probably not too different from the United States- if anything, we probably have a larger proportion of food transported by road instead of rail or internal waterways.

So in getting to work on my bicycle, I am probably (indirectly, statistically) burning enough fossil fuel to make 3375 kcal of energy. How much is this?

Looking in the back of my 1st year chemistry textbook, I calculate that burning 1 mole (114 g) of octane should produce 1066 kcal of energy. Thus I am using about 360 g of fossil fuel in cycling to work: this is only about half the amount I would burn in the car, so voila, cycling to work is a good idea! Especially if we were to repeat the exercise and take the whole supply chain for producing and distributing the petrol into account.

Except... my 1066 kcal was the theoretical maximum, and I have no idea whether the University of Michigan study uses the actual energy produced by burning the fossil fuel, or the theoretical energy content. If it is the first, then cycling and driving are becoming pretty much of a muchness. And if my diet consists of meat from non-native animals and fresh fruit and vegetables airfreighted from exotic locations, than I am doing the environment a grave disservice if I don’t drive to work...

#81, The Overthrowing

In the name of Allah, the Compassionate, the Merciful.
When the sun is overthrown, and when the stars fall, and when the hills are moved, and when the camels big with young are abandoned, and when the wild beasts are herded together, and when the seas rise, and when souls are reunited, and when the girl-child that was buried alive is asked for what sin she was slain, and when the pages are laid open, and when the sky is torn away, and when hell is lighted, and when the garden is brought nigh, then every soul will know what it hath made ready.
Oh, but I call to witness the planets, the stars which rise and set, and the close of night, and the breath of morning, that this is in truth the word of an honoured messenger, mighty, established in the presence of the Lord of the Throne, one to be obeyed, and trustworthy; And your comrade is not mad. Surely he beheld Him on the clear horizon. And he is not avid of the Unseen. Nor is this the utterance of a devil worthy to be stoned.
Whither then go ye? This is naught else than a reminder unto creation, unto whomsoever of you willeth to walk straight. And ye will not, unless (it be) that Allah willeth, the Lord of Creation.


Our honourable treasurer says there is no place in our democracy for people who want to introduce Shari’a- what a tosser! You can’t just suddenly arbitrarily decide that our present system is the acme of excellence and try to preserve it exactly how it is forever. It wasn’t so many years ago I remember his telling us that our constitution was no good and we had to throw it our and get a new one. There is no difference in principle between replacing the Queen with some party political hack and replacing her with a Caliph or a democratically elected council of mullahs. Show some consistency, Pete! If someone thinks the country should be run in a completely different way, they have the right to form a political party with a clearly stated platform of introducing cargo-cult socialism, or Islamic Law, or whatever, and if they manage to get voted in, they should be able go ahead and do it.* That is what democracy is supposed to be about. A party tells you what its policy is, and then you vote for it or not. You don’t say, for instance, that you’re ‘never ever’ going to do something, and then do it...

*: If Barnaby Joyce lets them.
