The Poor to the Rich: Stand by Me

Posted by Tioti Timon *

The debt of developing countries refers to the external debt which is incurred by their governments, typically in amounts beyond their governments' ability to repay. Therefore there have been ongoing calls for lifting this burden of debt, with significant debt cancellation having been granted in 2006.

However, it is not merely a matter of lifting the burden of the debt which poor nations have towards the rich.  I argue here that the rich nations have a debt to the poor, on the basis of the disastrous effects of those activities which have made them rich.  The subject is vast, and the debate is obscured by many factors.  I begin therefore with a description of my personal experience, which reflects the overriding concern of my own Pacific nation. 

Casting my mind back over many years, the palm trees where I once played and climbed as a child have gone. What little fresh water there was is now contaminated by salt. There is no rain, and all the low lying land is being washed away. With a lack of fresh water, our children suffer from dysentery. The graveyards of our relatives are being swallowed up by the sea. For the old people this is very hard. Our culture and our history is being washed away. 

It is a story which may be told in many different forms, in many different places.  Life is degraded through the so-called progress of humanity, and those on the receiving end find themselves helpless.

As the world merges into the technological age, what future is there for the powerless, innocent people struggling to get on with life?  Whom shall we blame, and would the perpetrator accept their being blamed?  Or is blame even necessary to motivate compassion?  Parliamentarians speak easily of justice, peace, security, and a higher standard of living in their campaigns.  Is it bringing justice to the lowly and powerless who have no say?  Everything in this world is a race to be seen, and be ranked at the top of all human powers. 

Why do developed, rich countries give aid to developing countries, yet fail to make the changes which matter most?

Are there any lessons we can draw from traditional Christian teachings? When Jesus came to the world, He brought justice with a new set of rules.  Love one another as you love yourself—a new commandment not only for the individual, but to level everyone on the hierarchy of standards, and to bring peace within the world nations.  Many of the global countries profess to be Christian countries, whether through heritage or through living faith.  Why not use the new commandment of Christ, and care for our helplessness on washed out islands during these times?

The people of Kiribati, who are at the top of the list of nations endangered by global developments, cry for the world to have compassion, and to think of us, a Third World struggling nation who have no say, and have no power to protect ourselves from the side-effects of the technological age.  The fact that our government needed at all to beg the larger countries at Copenhagen shows the ignorance of the world with regard to their tiny younger brother begging for help in times of need.

A cry for justice may be scoffed at with ignorance, as our cry would hold back bigger countries in their race for the most powerful position.  Our cry is a mere bump on the road for them, but we pray to our loving heavenly Father that someone will emerge with a plan, to convince our big brother nations to help and stand by us this time.

We call for nations not merely to think in terms of others’ debt towards them, or the neutralisation of that debt, but to think of their own debt towards others.  I conclude by quoting the preamble of a statement by the Australian Uniting Church on Human Rights: 

‘We believe that God has given humanity gifts and skills for the benefits of the earth and humanity itself. These gifts includes the capacity for love, compassion, wisdom, generosity, and moral choice.  They come with the responsibility to ensure the health and wellbeing of present and future generations and the earth.’

Particles Dreaming

Reflecting on the Double Slit Experiment

What do particles know?

The so-called ‘double-slit experiment’ is a demonstration that light and matter can display characteristics of both classically defined waves and particles. It is also said that it displays the 'fundamentally probabilistic nature' of the universe at the quantum scale.

The original intution of Thomas Young (back in 1802) was to reproduce the cancellation of water waves, but with light; the double slit was simply used to yield two exactly identical light sources (the same, divided in two). Notice the straight lines that seem to radiate from the source of the water waves: they are made of the cancellation of each other, and are analogous to the dark regions on the five-step picture (below), a true depiction of the impact of electrons in an experiment made by Tanamura.

In the de Broglie–Bohm theory (also called the Bohm interpretation) of quantum physics, the reason why single particles seem to interfere ‘with themselves’, in other words, the reason why, in the double-slit experiment, even single particles ultimately form a figure of interference despite of the fact that they are not emitted as beams but one after the other (see the 5-step process, below), is because each of these particles have a kind of pilot wave which does interfere with itself in some circumstances like the double slit apparatus. The analogy of the sonar helps to explain the phenomenon : picture a dolphin who would have to echolocate through two holes and you get the picture!

Bohm had many analogies for the quantum potential, his revised version of the pilot wave. The sonar is one of them. The information given by the surroundings guides the dolphin, it is called 'active information'

However, what this analogy leaves unattended is the fact that particles do not "send" signals to the surrounding and do not "wait" for this signal to bounce back. Another analogy far remote from the sonar one, was given by Bohm : each particle is like a piece of an hologram, each contains information about the whole, but each is concretised in a specific context.

The 'echolocation' process would be more like a pulsation between the particle as a located entity and the particle as one concretion of the whole. Pulsating infinitely rapidly between being-discrete and being-the-whole, the particle would be more like a process taking the form of an object.
What kind of "thing" can be everything half of the time and something the rest of the time?

Humans, for starters. We, as particles, tend to forget that we also are the whole, each night. We dream.

Are We All Scientists?

Posted by Thomas Scarborough

What is it that separates scientific discourse from our ordinary, everyday discourse? Do the two represent separate, independent languages? Or are they fundamentally the same? Are we all scientists?

I first became aware of this question – not that it was new then – when I witnessed a boatsman surfing a reef at high tide. The timing was a special skill that depended on an intimate knowledge of the regularity of the waves which bombarded the reef. Basically, said the boatsman, the waves came in threes – although it was more complex than that. Was this science? In fact, where did science begin and where did it end?

Many thinkers suppose that there are two kinds of discourse in this world: the language of science, and the language of mind. The fundamental difference, writes philosophy professor Michael Luntley, is that the language of science allows only for the physical properties of things, while the language of mind has to do with perspective.

This distinction may not in fact be necessary. Is it not a matter of perspective  as to how we arrange the physical properties of things?

The novelist and critic Samuel Butler considered (to put it too simply) that science merely has to do with the conventions on which people act, and these conventions vary. This merely needs to be noted, however. It is not of great importance to this post, other than to show that it has been considered. More important is individuation:

Our reality – if we try to imagine it before our minds make any sense of it – has been variously described as an undifferentiated stream of experience, a kaleidoscopic flux of impressions, or a swirling cloud without any determinate shape. William James famously wrote of ‘one great blooming, buzzing confusion’.

To make sense of this confusion, then, we need to break up the undifferentiated stream of experience – sounds and sights, surfaces and motions – into individual units. And while the process of doing so may seem to be quite natural and simple to us, what actually happens is extraordinarily complex.

From our earliest childhood, we begin to individuate people, playthings, animals, and a great many things besides. Before long, we begin to look at picture books in which individuated things are represented in pictures, with their names printed underneath: dog, cat, apple, orange, sun, moon – and so on.

Importantly, during this process, we strip off many of the relations which are associated with a thing, and seek instead to create something which is self-contained. In Hegelian-style philosophy, such individuated ‘things’ are said to be abstract, insofar as they are thought of in isolaton from the whole to which they belong.

Take the example of a ‘horse’. When we speak of a horse as an individuated thing, we have little interest in what it eats, or if it sleeps, or even whether it has four legs or three. It is something else that makes it a ‘horse’. To put it another way, when we individuate something, it loses some of its informational content. While in reality, it is impossible to imagine a horse without air, or food, or something to stand on – and innumerable things besides – the individuated ‘horse’ needs none of this.

Even at the same time, however, we carry all of the associations of individuated things in the back of our minds. They are present with us even as we exclude them. That is, we do not completely forget what these things are in their totality, even though we individuate them.

Consider the statement, ‘The horse fell from the top of the cliff.’ While we all know that it is likely that the horse is now dead or seriously injured, the individuated unit ‘horse’ does not obviously contain such information. To put it another way, to individuate something does not mean that we truly and completely individuate it. It may be more accurate to say that we allow some aspects of it to recede yet not to leave the picture.

In fact, this is very much what we do with scientific research. In our experiments, in order to make any progress, we screen out unwanted influences on independent variables. Physics, wrote the 20th century linguists Wilhelm Kamlah and Paul Lorenzen, investigates processes by progressively screening things out. That is, we ignore unwanted relations.

Whether we say, “This cake needs thirty minutes in a hot oven” (a highly abstracted statement), or “I wonder whether it will rain today,” we are doing what the scientist does. We are removing informational content, to relate abstract things, one to the other.

With this in mind, we ‘do science’ all day long. There is little difference, in the most fundamental way, between the Hegelian-style abstraction of our everyday thinking and our scientific pursuits – except that, with science, we make a more rigorous effort to put out of our minds the relations which are unwanted.

Our scientific discourse, therefore, is closely related our ordinary, everyday discourse. We are all ‘scientists’.

‘Ordinarily, hypotheses used in science are more precise
and less vague than those adopted in everyday affairs.”
—W.V. Quine and J.S. Ullian.

Is Consciousness Bound Inextricably by the Brain?

From Qualia to Comprehension

Posted by Keith Tidman

According to the contemporary American philosopher, Daniel Dennett, consciousness is the ‘last surviving mystery’ humankind faces.

Well, that may be overstating human achievements, but at the very least, consciousness ranks among the most consequential mysteries. With its importance acknowledged, does the genesis of conscious experience rest solely in the brain? That is, should investigations of consciousness adhere to the simplest, most direct explanation, where neurophysiological activity accounts for this core feature of our being?

Consciousness is a fundamental property of life—an empirical connection to the phenomenal. Conscious states entail a wide range of (mechanistic) experiences, such as wakefulness, cognition, awareness of self and others, sentience, imagination, presence in time and space, perception, emotions, focused attention, information processing, vision of what can be, self-optimisation, memories, opinions—and much more. An element of consciousness is its ability to orchestrate how these intrinsic states of consciousness express themselves.

None of these states, however, requires the presence of a mysterious dynamic—a ‘mind’ operating dualistically separate from the neuronal, synaptic activity of the brain. In that vein, ‘Consciousness is real and irreducible’, as Dennett's contempoary, John Searle, observed in pointing out the seat of consciousness being the brain; ‘you can’t get rid of it’. Accordingly, Cartesian dualism—the mind-body distinction—has long since been displaced by today’s neuroscience, physics, mathematical descriptions, and philosophy.

Of significance, here, is that the list of conscious experiences in the neurophysiology of the brain includes colour awareness (‘blueness’ of eyes), pain from illness, happiness in children’s company, sight of northern lights, pleasure in another’s touch, hunger before a meal, smell of a petunia, sound of a violin concerto, taste of a macaroon, and myriad others. These sensations fall into a category dubbed qualia, their being the subjective, qualitative, ‘introspective’ properties of experience.

Qualia might well constitute, in the words of the Australian cognitive scientist, David Chalmers, the ‘hard problem’ in understanding consciousness; but, I would suggest, they’re not in any manner the ‘insoluble problem’. Qualia indeed pose an enigma for consciousness, but a tractable one. The reality of these experiences—what’s going on, where and how—has not yet yielded to research; however, it’s early. Qualia are likely—with time, new technologies, fresh methodologies, innovative paradigms—to also be traced back to brain activity.

In other words, these experiences are not just correlated to the neurophysiology of the brain serving as a substrate for conscious processes, they are inextricably linked to and caused by brain activity. Or, put another way, neurophysiological activity doesn’t merely represent consciousness, it is consciousness—both necessary and sufficient.

Consciousness is not unique to humans, of course. There’s a hierarchy to consciousness, tagged approximately to the biological sophistication of a species. How aware, sentient, deliberative, coherent, and complexly arranged that any one species might be, consciousness varies down to the simplest organisms. The cutoff point of consciousness, if any, is debatable. Also, if aliens of radically different intelligences and physiologies, including different brain substrates, are going about their lives in solar systems scattered throughout the universe, they likewise share properties of consciousness.

This universal presence of consciousness is different than the ‘strong’ version of panpsychism, which assigns consciousness (‘mind’) to everything—from stars to rocks to atoms. Although some philosophers through history have subscribed to this notion, there is nothing empirical (measurable) to support it—future investigation notwithstanding, of course. A takeaway from the broader discussion is that the distributed presence of conscious experience precludes any one species, human or alien, from staking its claim to ‘exceptionalism’.

Consciousness, while universal, isn’t unbounded. That said, consciousness might prove roughly analogous to physics’ dark matter, dark energy, force fields, and fundamental particles. It’s possible that the consciousness of intelligent species (with higher-order cognition) is ‘entangled’—that is, one person’s consciousness instantaneously influences that of others across space without regard to distance and time. In that sense, one person’s conscious state may not end where someone else’s begins; instead, consciousness is an integrated, universal grid.

All that said, the universe doesn’t seem to pulse as a single conscious entity or ‘living organism’. At least, it doesn't to modern physicists. On a fundamental and necessary level, however, the presence of consciousness gives the universe meaning—it provides reasons for an extraordinarily complex universe like ours to exist, allowing for what ‘awareness’ brings to the presence of intelligent, sentient, reflective species... like humans.

Yet might not hyper-capable machines too eventually attain consciousness? Powerful artificial intelligence might endow machines with the analog of ‘whole-brain’ capabilities, and thus consciousness. With time and breakthroughs, such machines might enter reality—though not posing the ‘existential threat’ some philosophers and scientists have publicly articulated. Such machines might well achieve supreme complexity—in awareness, cognition, ideation, sentience, imagination, critical thinking, volition, self-optimisation, for example—translatable to proximate ‘personhood’, exhibiting proximate consciousness.

Among what remains of the deep mysteries is this task of achiveing a better grasp of the relationship between brain properties and phenomenal properties. The promise is that in the process of developing a better understanding of consciousness, humanity will be provided with a vital key for unlocking what makes us us.

Picture Post #20 Olber's Paradox raising insoluble questions

'Because things don’t appear to be the known thing; they aren’t what they seemed to be neither will they become what they might appear to become.'

Posted by Martin Cohen and Tessa den Uyl

A NASA  image from the Hubble Telescope looking into the 'Deep Field'

This is a patch of BLACK sky - empty when initially seen - even through the largest earthbound telescopes. Yet, with the  Hubble space telescope and a long-enough exposure time, even the darkness of space soon comes to glowing life. The point is, every bit of sky is actually packed with light - not merely with stars but with uncountable distant galaxies.

Heinrich Olbers (1758–1840) was a Viennese doctor who only did astronomy in his spare time, but realised that there was a bit of a logical problem about the night sky. And ‘O’ is for ‘Olbers Paradox’*,  which can be summed up by saying that if the universe is really infinite in size, the the night sky should not only be bright – but should be infinitely bright. Put short, we should see stars everywhere we look. So why don't we and why isn't the night sky all lit up ?

The paradox touches upon profound issues in cosmology, or the study and theory of the origins of the universe. Simply saying that most of the stars are too far away to see is not enough. Certainly it is true that starlight, like any other kind of light, dims as a function of distance, but at the same time, the number of light sources in the ‘cone of vision’ increases – at exactly the same rate. In fact, on the mathematics of it, given an infinite universe, with galaxies and stars distributed uniformly, the whole night sky should appear to be not black, not speckled, but white!

Olbers’ paradox is a ‘thought experiment’ in the very good sense that most of the reasoning is done by hypotheticals. What if the universe is infinitely large? And infinitely old? If the stars and galaxies are (on average) spread out evenly?

Various possible explanations have been offered to explain the paradox. Such as that stars and galaxies are not distributed randomly, but rather clumped together leaving most of space completely empty. So, for example, there could be a lot of stars, but they hide behind one another. But in fact, observations reveal galaxies and stars to be quite evenly spread out.

What then, if perhaps the universe has only a finite number of stars and galaxies? Yet the number of stars, finite or not, is definitely still large enough to light up the entire sky…

Another idea is that there may be too much dust in space to see the distant stars? This seems tempting, but ignores known facts. Like that the dust would heat up too, and that space would have a much higher. The astronomers who took this image claim it shows some kind of spectral shift into the red specturm. Or is it only the dust? The questions are not really resolved, even yet.

So what is the best answer to Olbers’ riddle? The favoured explanation today is that although the universe may be infinitely large, it is not infinitely old, meaning that the galaxies beyond a certain distance will simply not have had enough time to send their light over to fill our night sky. If the universe is, say, 15 billion years old, then only stars and galaxies less than 15 billion light years away are going to be visible. Add to which, astronomers say that the phenomenon of red shift may mean some galaxies are receding from us so fast that their light has been ‘shifted’ beyond the visible spectrum.

After reading this, and then standing here on planet Earth and watching the night sky, one might feel a little trapped by the questions. Our sight is limited and it always will be but maybe this is our hope for we can continue to philosophise: afte rall, what are we thinking? The picture above might as well represent pieces of coloured glass, under water visions where fluorescent life flows in deep dark sees, a pattern for printed cloth. Our brain only represents what we think we see, not necessarily the reality in which we live? In the incredible immensity of space, mankind has always been aware of this, even if, once in a while, the tendency is to forget.

* Although the paradox carries Olbers’ name,  it can really be traced back to Johannes Kepler in 1610.  In Wittgenstein's Beetle and Other Classic Thought Experiments, Martin’s book, which talks a little more about all this,
