That’s about it
This week marks the start of the first sitting in Parliament for the Rudd Government.
Today Prime Minister Rudd gave the apology to the Stolen Generation.
So, that’s about it for this Pharoz blog.
[Can't quite say that it was fun though]
***
I will continue to write posts on the Becrux blog.
Hope to see you there…

It might be an idea to summarise the *Solar Energy category in Pharoz and put some of these posts into the Becrux (Mimosa) blog with links to the relevant Pharoz posts.The basic categories would be something like:
- Energy efficiency at a network level
- Storage of electrical energy
- Transport of electrical energy
- Fixing electrical energy
- Transverse horizontal wind turbines
- Transition from coal power to renewables (system wide)
- Carbon dioxide – Removal, transformation and disposal of CO2
- Applying usable kinetic energy to spacecraft through remote lasers
There is a separate post for each of the broad categories above with links to the relevant Pharoz posts. The more readily achievable ideas will be put in the Becrux blog while the more hypothetical will be kept in Pharoz. In the list above the topics in lines 1, 4, 5, 6 and 7 are immediately realistic, while those topics in lines 2, 3 and 8 are more futuristic. The topics in lines 2, 3 and 8 above work with each other as a system – all three would have to be realised to start up large volume space travel. Whether this is achievable now is a mute point. First you have to be able to imagine what you need to do.
And it’s not fantasy like in a book like The Hitch-hiker’s Guide to the Galaxy – these are incremental steps that can be researched to see whether they can be realised with current technology. Even if the answer to these questions may be NO now, it may be YES at a later stage.
And travelling in space is not a utopia. I expect people to organise themselves politically like they do now – with separate public and private realms, the rule of law combined with human rights, transparent and accountable governments, and so on.

Another idea for storing electrical energy. Capacitors can hold small amounts of electrical energy with little loss. When holding higher energies over time capacitors can fail, so the idea is to store high amounts of energy in capacitors for short amounts of time so that the capacitors do not become damaged. Pulses of electrical energy are stored by sending them circling through cycles of capacitors (and solenoids). This would involve large currents so it would have to be at superconducting temperatures. The question is whether you could configure such a complex system to hold large amounts of electrical energy, with a good energy density as compared to conventional fuels and storage methods. You would also have to consider the overheads of controlling such systems and keeping them at superconducting temperatures. I suspect that it may take some time to arrive at the point where such systems are commercially viable, if it were possible. It’s worth considering the idea at least.

The basic idea is that the light from a laser made with a gas will be at a frequency such that the light from that laser can be absorbed by that same gas in a special cavity at a distance removed from the laser, and thus cleanly ‘catch’ the energy from the laser so to speak. While the resonant cavity used to generate coherent light in a laser might be small in volume, the volume of the catching cavity of a relay satellite would have to be big enough to ‘hold’ all the energy transmitted at one time. To mix metaphors, such a catching cavity would need to be lined with something that keeps the energy bouncing around inside, as with a thermo flask, and the lense through which the laser light enters the catching cavity would have to have a large shutter like a camera so that it can be open for only a short amount of time.
There would need to be a process within the relay satellite that in effect draws quality energy (preferably not thermal) out of the excited gas being held, and it would be something of a reverse process to that in the laser that pumps energy into the resonant cavity filled with that same kind of gas to start with. That last step of drawing out the energy in such a catching cavity once it has absorbed the energy from a laser would be the most difficult. I think the other steps could be readily achieved. If this last step can be realised efficiently in practice then you could use lasers as a medium for transmitting energy, at least in space. The terminology I am using here is crude but I hope this conveys the basic idea.

Think about it. If a spacecraft were to be powered from remote energy sources what mechanisms would be available to to this? You could carry all the fuel from launch, use gravity near planets, electrical and magnetic fields would be too weak and dispersed and fixed solar panels wouldn’t collect enough energy to significantly propel the craft. Burning fuel to change the centre of mass in space seems sort of inefficient, even if it works. It has a single-cell biomechanical feel to it, like a free floating blob that inches along by periodically puffing up, shifting its weight and then contracting again.
If you could make a surface on a spacecraft that at a molecular level ‘kicks’ in a certain direction when it absorbs a photon of a specific frequency, then you might be able to move that spacecraft remotely through lasers. (I am using the term laser generically, the frequency can be outside the visible spectrum). Even if a small percentage of the incident energy (like 5%) could be used to safely move spacecraft in space that would significantly change the nature of space travel. Even so, at the moment you could call this science fiction.

Not as citizens and without appeal to ER and her courts, it’s the E-R identity that counts. There’s an interesting article at Online Opinion about so-called federated identities (Plurality of Identities). It’s interesting to consider the impact of computer technology on the way that people understand each other, at least within some communities, such as the security community. The thing about linking all of our various identities, whether recorded in a database or through comment files, into one federated identity, as it seems to be called, is the fact that each federated identity comes down to a number. A key field in most large databases is preferably a unique sequential number. To combine a large number of identities into one federated identity would mean making that database key number for the individual concerned the one main identifier that links it all together. That number would have precedence over any other kind of identity, even the person’s name. Anyone not familiar with database systems would possibly not understand these points and its significance.
Some of the main issues around such database systems are about who has access, how far the databases go (do they even get to see items scanned at a supermarket and paid for by credit card, the times and places that a car eTag was read, etc), whether the person involved has any say in what is recorded and even systematic fraud. Systematic fraud is the most serious problem because it would most likely be difficult to detect as fraud. With things stored only electronically it would be relatively easy to do Orwellian revisions. Tied to that issue of integrity would be the reputations of many powerful people and protecting reputations through enforcing secrecy of the system. We saw some of this with the Haneef case. It’s about power and exercising that power in order to keep that power. It’s a far cry from “government of the people, by the people, for the peopleâ€. Transparency of these systems protects the public, while more security personnel does not necessarily mean more security, it could help small pockets of organised criminals become entrenched within the secret system. But of course, these systems persist as long as they are considered by the public to have integrity or the public no longer has any option but to comply. I wish I didn’t have to make these kinds of comments.

Here’s a train of thought that is sort of difficult to express.
The monotheistic religions start with an all powerful God which sort of provides a clean slate for creation, as with in the first chapter of Genesis. This idea of creation out of apparent formlessness has a parallel with some kinds of human action – the claim of terra nullius in colonial times is a strong example, but also for more mundane acts of creativity. It could also allows for free will, but there are many other cultural ways of doing this as well.
Such an absolute claim made by anything or anybody other than God must be followed by a Fall of some kind, a realisation of limits.
But even so, even after the Fall there is still the result of the intended action without consequence. Something is broken and it is difficult to point out what that is. It traditionally goes by the name of original sin and is assumed to be with every person born after the Fall. (These ideas are a discussion using some religious concepts.) But perhaps rather than being based in a flawed humanity, the original sin may be based in an unrealistic concept of God as omnipotent. The Fall transfers the blame away from the concept of a perfect God. And that precious idea, the omnipotent God, remains as it was originally.
There is perhaps a sense that sacrifice is sometimes a consequence of an initial audacious stepping out. The creative act may have been audacious and the person paid for it, but the consequences remain and the assumption of a clean slate within which that initial audacious action may have taken place becomes confirmed in some way. It’s like a disruption to the natural order that becomes solid through irreversible consequence and sacrifice.
But then in Christianity, what would it mean that God would be sacrificed in the person of Jesus? It is like a more humble concept of God, even while maintaining the original concept of an omnipotent creative God. There is still the possibility for creation and free will in human life but the blame, so to speak, for the Fall may not be all due to original sin in humanity.
And then again, the creative potential is still there and more honest and realistic. You could say that Christianity also tries to redeem God, even if that would not be admitted. It is difficult to express this idea properly. It’s not taking the mickey. The twentieth century ground on after Freddy’s claim that God is dead with the quick-fix failure of an idea to try to substitute Man into the role of omnipotent God. Twentieth century history and postmodernism have thoroughly ridiculed that idea.
So what does the Christian story have to say about the nature of God? The conventional Christian story is that Jesus redeemed humanity through his sacrifice, but could the Christian story also be about redeeming God? Now that would be a strange twist in the story! But ideas take a while to take root, if there is anything to this new perspective.
***
There are obviously different cultural contexts for the phenomena of sacrifice. In the Judeo-Christian religions it has various meanings, possibly related to the way God is understood. I think that in some ways of living, as with Buddhism which does not believe in an omnipotent God, there are different notions such as generosity and meditative practice. It’s a difficult topic to talk about but it is important because a notion of God is still part of our culture. In a way the Christian approach brackets [God] , unless of course they make out that Jesus of Nazareth was something of a triumphant Uebermensch. That would be missing the point in my opinion.

And creation here is meant as a cultural act by a person. The natural world changes continually with some aspects of things changing while other aspects remaining constant (such as mass/energy, momentum, etc). A creative act by a skillful person can have an effect in the physical world but that is more through something like guiding impersonal physical processes to create some thing or situation that may have been imagined. It would be nearly impossible for any person to construct even a biological cell or a strand of hair from the raw elements, but everything that goes into reproduction, eating and keeping a person healthy is covered through culture and the ways we live. Creative action is not about literally placing every atom in place from moment to moment, which couldn’t be done in any case.

These are not value judgments or opinions. The posts in this category are about seeing these topics about western religion and modernity in a different way. Whether I like it or not, or whether you like it or not, is beside the point. What is important is that the ideas have consistency and that the ideas hold together. It is very difficult to explain a different paradigm and it is possibly something that can only be evaluated over a few generations.The point made in this post is that the problem of evil is related to the way that God is understood. The way a culture defines The Good will impact on the way that the culture defines what it sees as being not that Good. With the Judeo-Christian religions God is all good and all powerful so that prevents analysis to an extent. In pre-modern times you could not criticise directly the way that God was conceptualised for fear of excommunication, exclusion or worse. Even so, there also seemed to be something culturally unconscious, a sense of justice or truth maybe, that over time corrected for the nature of the problem.
Translating the Bible into local languages and the printing press had a profound effect on the cultural understanding of God within Europe. The Reformation was also about things such as the relation of the church to the people, the nature of authority, reading the Bible and its stories for oneself, having religious services that people could understand, and so on. The mystery in pre-Reformation religion was not just theological but through ignorance and the power relations of the clergy to the people.
Perhaps our problem today has to do with -Â being stuck with the need for an ABSOLUTE Good without really acknowledging it. And being too clever and sophisticated to admit to such a cultural need. Think of nationalism, ideologies and totalitarian states, greed and consumerism, the fuss about perfection in our bodies and looks, fundamentalisms of all shades and colours, the way the public and media places celebrities in the public spotlight and then criticises every single perceived imperfection, as with Diana. God hasn’t died, He’s just gone kitsch. And it’s not a Good look. We still hanker for perfection, or carry on as if we expect it, somewhere; but still rip anything to pieces that we momentarily set our collective hungry gaze upon.
The ambiguity is in the way that God is conceptualised in our culture. The churches don’t really understand what is going on. They seem to be stuck repeating tired formulas or else tarting up their image of God and church to match the times. It’s difficult to explain…

I was just browsing through some wikipedia pages: constructivist epistemology, theodicy, omnipotence and a few others about the history of ideas.
One of the apparent problems with the conventional way that the idea of God is understood has to do with the problem of evil. If God is all powerful and all knowing how could there be evil in the world? Theodicy tries to reconcile the two.
The conventional way that God is conceptualised seems to be in terms of essences. Some questions in the philosophy of religion are about trying to define the nature of God and then to reason about it. Theology takes God as self-evident and goes from there. This is only a mug’s one-line descriptions of large fields of knowledge.
And of course Man was made in the image of God.
These questions are also tied to questions about free will.
I think one of the most important aspects of God has to do with the Creation stories. In the religions with a monotheistic God those creation stories are like an unconscious template for creative human action, at least in our small ways. That creative process is replayed repeatedly and you might even attribute free will to that repetitive creative process.
Religions are socially constructed and to an extent even the concept of God is also socially constructed (although that still means that it is beyond any one person to fathom the full extent of the idea of God over the past, present and future or even in any one moment). You still need a name for something that is unknowable and can not be named (or defined) in the same way that other physical objects, things or events can be named.
The important thing for the creative process is the protection, like a nest for an egg, so that the new creation can be brought into the world. Saying that God has the qualities of omnipotence, omniscience, omnipresence and benevolence provide that nurturing space. It would not provide the authority and confidence for free action without that. Still, therein also lies the problem of evil. There is the Genesis but after that there also needs to be a review. Free will without concern for the consequences is a problem. And then there is always other people and society to consider. Perhaps it is characteristic of the monotheistic religions to have cultures that emphasis bold beginnings but then suffer a Fall of some kind, unless difference and the social are acknowledged.
So there is a socially constructed God construed as being specifically not socially constructed at all but that is instead eternal, all powerful and unchanging – universal. And then there are the actions of the faithful that follow, assumed to be sanctioned by an all powerful, universal God. There is a sense that this on-going creation sometimes tramples and trespasses beyond legitimate boundaries and limits. Social exclusion and power is sometimes used to entrench that exclusive worldview.
But that conventional monotheistic approach sometimes doesn’t look that good in a plural society, and claims of moral authority can sometimes come undone. At least with a Holy Trinity the emphasis could be shifted to one of the other two. Perhaps the Holy Spirit is more suitable for these times. It was also there at the beginning. And mankind still remains to be made in the image of God.

One of the main differences with this new interpretation is about recognising the context and limits of individualism. It’s difficult to describe succinctly, and this is making a very crude attempt of it too.
In pre-modern times the church and local community did provide a context and limits within which most people lived. I suppose that the Enlightenment ideals grew over a long time out of that solid understanding of society and people’s place in it. Yet the Enlightenment with it’s industrialisation, science, migration from rural communities to large cities, and occasional crises and revolutions also undermined that social context where people can live safely and contentedly.
Pre-modern life was certainly not idyllic. Yet you also find with some of the revolutionary ideologies that they idealise aspects of that pre-modern life. Rousseau could be a source for a quote at this point. You could include some kinds of religious fundamentalism, national socialism and communism as ideologies that tried to turn the clock back or that try to harness modern science within something like a pre-modern social order (that just happened to also be authoritarian). Personally I think the reality of communism had nothing to do with a classless society. The people in the dominant political party of one party states constituted an elite class for those societies. Marx deliberately tried to find a way to reconnect workers in modern societies with the product of their labour as was the case in pre-modern societies, at least in theory. Communism may be a world apart from pre-modern society, but there are some important threads that link the two, so the claim made above is not as far-fetched as it may at first appear.
The Enlightenment did, however, emphasise the Individual; the rational individual. In the popular mind there is still a strongly negative connotation to some of the Enlightenment ideals. I think part of this is because science and industry can appear indifferent to human society and a person’s place in it. It is really tricky to untangle these ideas. Modernity does not in general pay due attention to society and community, and that may be part of the cause for cynicism about science and industry.
All I wanted to say, or am asserting, in this post was that the pre-modern world view is based more around narratives of people and how they live in communities. The fundamentalist religions seem to be harking back to a pre-modern world. Modernity grew out of a pre-modern world, obviously a tautology, but it initially took some things for granted, such as society, in ways that we no longer even consider or may be aware of these days. I am not saying that the social context in those early modern days were all good, or even that good for most people. It would have been a hard life. Perhaps what I am saying is that the problem may not be with modernity and the Enlightenment ideals, but that we have over time lost the social context and that we have to consider that in theory as well.
The left and right political divide has formed in an ambiguous way where the left champion society but with Enlightenment ideals, while the right champion the Individual but more in a pre-modern conservative context. There is a strange twist in the old way of dividing left from right. Both sides of the political divide could claim to represent people in communities, and yet both sides could miss the point.
An alternative, as stated many times through this blog, is to recognise the difference between public and private. The public world is about testing knowledge, while the private world is more about affirming others in our immediate circles. You can have both, but there is a structure that separates the two modes. Science as well as narratives. That approach is usually found at the centre of the political spectrum. Does that make sense?
