Energy: What Exactly Is It? Davy Jones - 2011



No matter how much you push the envelope – it will always be stationery

About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion was known as the Big Bang.  At the moment of this event all of the matter and energy was contained at one point.  What existed prior to this event is completely unknown and is a matter of pure speculation.  (LaRocco)

The above paragraph is an excerpt from an article, entitled, ‘The Big Bang – It sure was BIG’!  Note the comment – all of matter and energy was contained at one pointnot - all of matter and energy was created at one point. 

There’s no great mystery in this statement of course, it is a simple matter of physics – energy - as we ‘know’, cannot be ‘created or destroyed’ - it can only be transformed!  The arguable word in the sentence is the inclusion of ‘matter’ being contained at this point.  However, given that energy and matter are, according to Einstein (E=mc2), one and the same, the semantics of the sentence are perhaps neither here nor there.  What is possibly more important in this reflection is the fact that many people actually refer to the Big Bang as the point at which the universe was ‘created’!  That basic misinterpretation muddies the cosmic waters before any logical thought as to the conceivable possibilities surrounding the greatest of all mysteries, can be considered.  Just to underline the immense implications contained in this short paragraph, one should also consider; all energy and matter must mean and include – dark energy and dark matter – or quite simply – the basic constituents for everything thereafter!  

My thoughts as I read through the above article drifted to the most basic question – ‘what exactly is energy’?  On the face of it, a simple and certainly most obvious question, which would soon be resolved by a little research?  (I have been known to make naive suppositions from time to time).

Within a short while I found myself frustrated at every new Internet page.  Information categorising energy in its various forms – thermal (heat) – chemical – electrical – radiant – nuclear – elastic – sound – mechanical and luminous (light), abounded.  All of the indicated forms of energy can of course be divided into the two generic groups of kinetic and potential energy. 

The Internet also provides an overabundance of data relating to the above classifications, detailing where, when, how, and why they occur.  There is also much made of the fact that energy is a physical measure that expresses the amount of work that can be achieved by a force; it then follows that all forms of energy are measurable through the use of mathematical symbols.  A lot of interesting facts and figures – but no concrete explanation of exactly what energy is! 

Eventually, I stumbled upon a Science Forum discussion page that seemed to offer ‘something’ I could finally nail down!   The opening question appeared to offer precisely the information I needed: ‘What exactly is energy…without using symbols and metaphors’?  There was no doubt about it – as I waded into the opening comment – the first participant began by stating the obvious – that molecules move, they are ‘hot’ and have lots of kinetic energy.  But, then asked: what exactly is energy?

The discussion progressed along similar fumbling lines to my research – going through all of the categorisation mentioned above, including the mathematical concepts involved.  Several comments into the forum I came across the first glimmer of hope in the following comment: …’energy is the capacity to do work of some sort.  It is categorically not a substance in itself that pervades the universe’. Naturally a swift rejoinder to this comment followed, which suggested that if the previous writer thought energy was just an abstract concept – they should try sticking a fork into an electrical socket.  Whilst amusing – this comment still didn’t assist me in my quest to define ‘energy’ per se.  We all know that ‘electricity’ is a form of energy.  And, as with just about every form of energy I can think of, in certain circumstances, too much of it can do extreme damage to the fragile human atomic structural arrangement!  At its worse – we call that damage – death – that being, in terms of physics, just another ‘changed state’ in a seemingly endless process!

The next comment suggested that ‘everything’ was energy because all matter, irrespective of state is a form of energy.  A fair enough comment – but it still didn’t answer the basic question!  It is amazing how trains of thought can become bogged down when dealing with oddly esoteric questions.  Further again into the discussion the term: ‘creation of the universe’ inevitably raised its head.  The very use of the word – creation – of course, suggests a creator – and therefore moves the discussion from a purely scientific one to a philosophical and spiritual one.  This manipulation of any discussion seems to be the ultimate human response when frustration and a lack of logical answers set in; a third party is introduced that conveniently provides all the answers.  Even the illustrious Einstein is recorded as resorting to the same conclusion at one very frustrating moment in his quest for answers.

Despite this natural diversion, the discussion continued in a reasonably focused direction.  Some participants were beginning to show obvious signs of frustration – evident in their comments becoming more personal and derogatory towards other forum participants.  Much was made of the fact that energy determines the path of change – energy is evident through observable change – and the amount of energy determines the rate of change. 

All pertinent points – but still none that addressed the original question: What exactly is energy?

Towards the end of the discussion there were a few comments relating to molecules and particles, and the movement of these ‘producing energy’.  Finally, a respondent came up with the following explanation:  Energy, he said, has no reality apart from its mathematical dependence on measurable variables.  The respondent noted that an object’s kinetic or potential energies are not measured – but the associated state variables are - velocity and position respectively. (Sic)

This answer was expanded upon, by one I assumed to be the convener, who warned that whilst it wasn’t an easy question to answer – that didn’t make the question impossible to answer.  He indicated most physicists know exactly what energy is, and continued thus: the concept of energy is ultimately a tool – invented by humans – to understand the world around us.  He stated that whilst this was not a definition of energy – the whole point was – energy can be MANY things and it is this vagueness that makes the concept useful.

As an example, he cites the notion of length – which is close to our primitive perception; length – we understand as being that there is, “here” and “there”.  The concept of energy, however, he describes as being a higher order type of tool.  It doesn’t correspond so simply to our direct experience in that no one can point to a primitive notion and state that it is an example of energy.  Therefore – energy – is simply an abstraction.  However, it does enable a unified description of diverse phenomena.  Energy, as such, is simply a tool and an additional way to organise our understanding of the universe. 

The writer wraps up by providing what he describes as an exact definition of energy: “Energy is the generator of time translations”.  Having given this murky definition, he explains that – this is why no one gives the exact definition of energy, because it takes years of intensive training just to comprehend what such a statement really means!

In this instance, I can only agree.  Having put myself through this meticulous research process, I now wonder what ‘diverse phenomena’ are?  I’m sure no one will ever bother to explain it to me – simply because I wouldn’t understand - even if they bothered! 

So, at the moment of the Big Bang – all diverse phenomena were present – or were they?

Any readers’ comments on this small reflection would be most welcome; particularly if a convincingly simple answer is forthcoming.

Theories Abound - Davy Jones


In a lecture, hosted by Fairfax in May 2012, entitled – A Guide to the Universe – Nobel laureate, Professor Brian Schmidt outlined his early ambitions.  He wanted, he said, to do something ‘really big’ and the biggest challenge he could imagine was - Measuring the universes’ past so he could understand its future!   
Professor Schmidt is also reported to have responded when asked the question – “ Where is the universe expending to?” – with the answer – “Into the future.”

Remarks such as this generate speculative thoughts; ideas of the ‘past’ and ‘future’ – of ‘beginnings’ and ‘endings’, are undeniably fertile ground for the inquisitive mind. 
This same type of question has arisen in the past  at Macarthur Astronomical Forum sessions, for example  ‘where did the universe begin?’  To which the general response seems to be – ‘everywhere – all around us or that is a question that has no real answer.’  Such responses, in my humble view, may not be quite correct!

Whilst a 2D or 3D vision of the universe is perhaps the more common, (understandably) human view – I suggest, as Brian Schmidt indicated, the 4th dimension – TIME – is vital when clarifying remarks relating to ‘aspects of the origin of the universe.’ 
Therefore – rather than seeking a 'physical location’ – which would be patently wrong – instead, the answer to - where did the universe begin – should simply be – at least 14 billion light years ago.

Similarly – the debate persists regarding the ‘shape of the universe’.  With a little research, one quickly discovers a number of ‘possible models’ – often diagrammatically represented in mind-bending ‘Escheresk – matrix detail’ (see M.C.Escher). 
Again though, in reality, it is not too difficult to visualize a realistic cosmos model – taking all four dimensions into account – as starting from a ‘point’ and growing or expanding exponentially over billions of years into a ‘bell-like shape’. This bell-like structure is - one must remember - countless light years across.
Imagine, if possible, looking down the bell of this ever-growing cosmic trumpet.  Again – TIME – is an indispensable factor and an essential element of this model. 

From my simplistic point of view, one could take a 2D slice across this trumpet-like representation of the universe at any point in the past 14 billion years.  The resulting ‘slice’ would reveal the exact state - stage – and extent of the universe at that exact point in ‘time’.  Add and overlay slice upon ever-widening slice over millennia and one eventually arrives at today’s complex cosmic arrangement. 
The only question remaining then is – what lies ahead?   Ahh – more questions; more musings.  Comments and other thoughts are always welcome ;-)

The Standard Model - Davy Jones


I realise that many MAS members will have read some of my scribbling.  However, as Face Book offers a wider audience, and many people seem to enjoy reading almost anything on the absorbing subject of astronomy, I thought I might adapt some of my archived work for others to peruse.
One of the columns offered in the now defunct club magazine – Prime Focus – was (tongue in cheek) called "Musings".  I liked that column very much simply because it offered a little more freedom of expression.  Without such freedom – Einstein and his ilk would never have been afforded the opportunity to day-dream – to hypothesize – call it what you will.  Just for the record – this approach in physics is called: "A thought experiment" or, if your name happened to be Einstein..."das Gedankenexperiment".
The first article I offered in that column went something like this:


Musings - hum - never thought of myself as a muse!  However, I'm quite surprised Prime Focus isn't essentially a compendium of musings - considering the universe is such a catalyst for musings generally.   
The word - muse - is these days perhaps more associated with day-dreaming or idle thoughts.  The origin though, is very different, with its roots way back with those - oh so Ancient Greeks.  There were nine Greek Muses; all with excellent family credentials in the gods' department - each associated with a different set of inspirational or philosophical disciplines.
Astronomy - falling well within these parameters - unsurprisingly, has its own dedicated muse, who went by the name of Urania.  Her cloak, naturally, was emblazoned with stars and symbols and her attention was centred at all times on the glorious heavens above. 
Urania, o'er her star-bespangled lyre,

With touch of majesty diffused her soul;

A thousand tones, that in the breast inspire,

Exalted feelings, o er the wires'gan roll—

How at the call of Jove the mist unfurled,

And o'er the swelling vault—the glowing sky,

The newborn stars hung out their lamps on high,

And rolled their mighty orbs to music's sweetest sound.

—From An Ode To Music by James G. Percival

Anyway, that'll be quite enough of that - thank you - it's time I revealed my musings of late.  I think the fairly confident discovery of the Higgs' Boson prompted my current line in musings.  With talk of various models of the universe coming to the fore, one cannot help but ponder, in an uninformed and somewhat crude manner, on the secrets that as yet lay undiscovered.
I have just a sneaking suspicion that whilst the universe in its entirety is indeed an extremely complex affair, once its origins are revealed, the 'processes' which brought it about will essentially be simple.  Funny how anyone can make that type of statement with hindsight (or in ignorance)!
Having exposed my unsubstantiated musings I am obliged to some degree to explain myself with - if possible - a terrestrial equivalence.   After a further extended period of musing - hopefully the following might make a skerrick of sense.
Think of an electricity generating station - coal - hydro - nuclear - gas - geothermal or whatever;  the initial process of generating electricity is much the same whatever the source or mode of generation.  The result is a reasonably clean and simple process that leads to the formation of pure energy in a distributable form; then the electrical energy bursts forth and leaves the plant at almost the speed of light – allow for attenuation caused by cables etc! 
It is now that the process of the conservation of energy begins in earnest, and is played out in a million different ways in our daily lives.  The pure energy aids the production of all the wonders of our modern world.  Not only that, at times it even causes the occasional tragedy.  Take the death of an unwary or complacent human being - an electrician or enthusiastic amateur - who gets themselves killed whilst working with this invisible Wunderkraft.  
All this complexity and drama, however, is developing far from the generating plant.   Once combined with other technologies the original clean and pure electrical energy may even produce yet more undesirable results, such as noxious waste products, or other less obvious pollutants such as light or noise pollution - think Rock Concert. 
Put quite simply: I envisage  the universe to be much the same - that which the enthusiastic, dedicated astronomer will spend hours - often enduring bitter cold nights or balmy mosquito infested summer evenings - to soak up through the eyepiece of equipment (that costs an arm and a leg) may simply be the debris released or created far from the original simple generating source of the pure energy. 
The natural processes of mixing gases - superheating - cooling - swirling - the generation of vast fields of electro-magnetic forces - and the intermingling of massive secondary forces, will obviously bring about many seemingly unexplainable phenomena.  Such phenomena may though in fact have very little to do with the original relatively simple source of production. 
Oh well - it was only a thought...
Whilst totally inconclusive, I have since had further thoughts on this particular subject, which I may at some time share with the world at large.  But Musing – does allow one to clear one’s mind of clutter.

Notes from Bryson:


Religion has never filled my ‘curiosity void’ or satisfied my intellectual hunger regarding the eternal questions – what comes after this life – and what is this life all about? 

Religion has likewise never offered me any great ‘spiritual comfort’ - simply because I don’t adhere to the proposal there’s a personified spook lurking deep within the confines of my body;  an amorphous entity awaiting blessed release from its beastly physical restraints.  The moment of my demise allows it to poof joyfully into the heavens, there to sit on a cloud whilst watching the world go by, until the world and indeed, the solar system, ceases to exist. 

The following passage from Bill Bryson, makes more sense to me than all the ghostly afterlife stories offered up by a plethora of religious organizations; after reading it I truly wonder why anyone could desire a more complex explanation, or a touchy-feely story to ease their often painful passing from this mortal coil.

Bill Bryson:  ‘A Short History of Nearly Everything’ pp. 176 – Ch. 9: The Mighty Atom.  Bryson rattles on about the properties of atoms a couple of times in his book, but the magic thing is, I found great comfort in the basic logic conveyed by such a simple scientific explanation that runs something like this…

…The great Caltech physicist, Richard Feynman, once observed that if you had to reduce scientific history to one important statement it would be:  ‘All things are made of atoms’.  They are everywhere and they constitute everything.  Look around you.  It is all atoms. Not just the solid things like walls and tables and sofas, but the air in between.  And they are in numbers that you really cannot conceive.
The basic working arrangement of atoms is the molecule.  A molecule is simply two or more atoms working together in a more or less stable arrangement…

At sea level, at a temperature of 0 degrees Celsius, one cubic centimetre of air (that is, a space about the size of a sugar cube) will contain 45 billion billion molecules. And they are in every single cubic centimetre you see around you.  Think how many cubic centimetres there are in the world outside your window – how many sugar cubes it would take to fill that view.  Then think how many it would take to build a universe.  Atoms, in short, are very abundant. 

They are also fantastically durable.  Because they are so long-lived, atoms really get around.  Every atom you possess (in your body) has almost certainly passed through several stars and been part of millions of organisms on its way to becoming you.
We are each so atomically numerous and so vigorously recycled at death that a significant number of our atoms – up to a billion for each of us, it has been suggested – probably once belonged to Shakespeare.  A billion more each came from Buddha and Genghis Khan and Beethoven, and any other historical figure you care to name…

So, we are all reincarnations – though short-lived ones.  When we die, our atoms will disassemble and move off to find new uses elsewhere – as part of a leaf or other human being or drop of dew.  Atoms themselves, however, go on practically forever.  Nobody actually knows how long an atom can survive, but according to Martin Rees it is probably 1035 years – a number so big that even I am happy to express it in mathematical notation…


For those who have ever puzzled as to why – if we are all made of atoms and likewise all other solid and nonsolid objects – we can’t walk through walls, or perform all sorts of other remarkable feats 

PP. 184
…, if an atom were expanded to the size of a cathedral the nucleus would only be about the size of a fly – but a fly many times heavier than the cathedral.  It was this spaciousness – this resounding, unexpected roominess – that had Rutherford scratching his head in 1910.

It is still a fairly astounding notion to consider that atoms are mostly empty space, and that the solidity we experience all around us is an illusion.  When two objects come together in the real world – billiard balls are most often used for illustration – they don’t actually strike each other.  ‘Rather’, as Timothy Ferris explains, ‘the negatively charged fields of the two balls repel each other… [W]ere it not for their electrical charges they could, like galaxies, pass right through each other unscathed.’ When you sit in a chair, you are not actually sitting there, but levitating above it at a height of one angstrom (a hundred millionth of a centimetre), your electrons and its electrons implacably opposed to any closer intimacy.

Libertas – Davy Jones



I strongly suspect that both my parents died not knowing or understanding why they had been part of this world.  I also suspect this sad prospect may be attributed to the majority of people in this world today – who possibly at some stage wonder what it’s all about’, but never quite fathom a satisfactory answer.  Questions and answers alluding to the meaning of life have been asked down the ages and many of the responses have been recorded throughout history.  I count myself fortunate to have been born at a time when both education and information have become more readily available to the public, thus, should we choose, allowing even the lowliest amongst us to form a reasonably informed opinion.

The ‘official’ responses for the – ‘meaning of life’ or ‘why we are here’ - range from those profoundly thought out, by philosophers both ancient and modern, to a plethora of glib answers - mere dogma - trotted out by any number of religious organisations.  The human race has grasped at these mostly false straws in the hope of finding some inner peace or some logical reason for ‘being’ with all the associated pain and joy (if you are lucky) that accompanies us from cradle to grave.

Throughout history, the human race has had an obsession with the ‘spiritual’ world; an obsession that often borders on fanaticism.  This fantasy spiritual world seems to have been created entirely in the human mind.  It is a world inhabited by demons, spirits, evil monsters, hobgoblins and gods of everything; a vibrant imaginary world, apparently holding all the answers, to seemingly unanswerable questions.  This world is an illusionary world, where man’s incredulity can be quickly and easily satisfied and impossible questions answered in one fell swoop.  But it certainly isn’t real!

The human race has sometimes been described as being ‘hard-wired’ in the spiritual sense. Since the earliest times - before recorded history – ancient peoples followed rituals, rites and ceremonies that shaped their daily lives and gave meaning to their very meagre existence.  They followed nature’s rules and performed the rituals that apparently guaranteed control of the uncontrollable.  If their efforts failed, then the fault lay somehow within them.  The god’s were seen to be punishing mankind for some lack of observance or failure to obey obscure - but man-made - rules - invented by a shaman or similar person, regarded as being in touch with the spirit world.

In a paper – entitled, Heavenbound A scientific exploration – Henig, makes the following observation…‘Lost in the hullabaloo over the neo-atheists is a quieter and potentially more illuminating debate. It is taking place not between science and religion but within science itself, specifically among the scientists studying the evolution of religion. These scholars tend to agree on one point: that religious belief is an outgrowth of brain architecture that evolved during early human history. What they disagree about is why a tendency to ‘believe’ evolved, whether it was because belief itself was adaptive or because it was just an evolutionary by-product, a mere consequence of some other adaptation on in the evolution of the human brain.’ HENIG, 2007

The gods, or spirit representatives, could also been seen as providing a ‘third party’ – a ‘big brother’ – who ensured that compliance was rewarded and non-compliance punished.  This ‘third party’ can also be blamed or beseeched in times of trouble.  Gods were and still are mankind’s security blanket in troubled times!  Likewise, the old remedy of basic reward and punishment – heaven and hell - are still applied in most religions today.

Could this be linked to something as basic as the need for self-regulation of a mind that has the capacity to be self-aware and has the capability to extrapolate beyond mere self into the minds of those with whom he or she shares their daily life?  Certainly, control and power play a part, even if its basis is illusionary. 

Whilst prehistoric peoples may not have employed psychologist per se, they almost certainly employed psychology on a fundamental level.  The power of the human mind to justify itself as an individual and to promote its own selfish personality and well-being over others has in all probability been with us from before the days when we descended from the trees.  As the human race has evolved so too has its ability to manipulate in fact – or in fiction – the world and those with whom they shared their daily lives.  Summed up in a few words – this amounts to little more than self-survival at any price.

Understanding the minds of the ancients is difficult from where we in the modern world sit – perched amongst our air-conditioned branches, with full bellies and nothing but idle thoughts, TV, or a plethora of modern day propaganda to fill our otherwise empty minds.  Trying to inhabit the world of the prehistoric cultures from this distance is very difficult if not impossible.

The prehistoric world is inconceivable to modern man; on a day-to-day basis it is difficult to know where to begin in describing its workings. 
Shamanic practices held sway, and from our understanding, a philosophy similar to the Aboriginal Dream Time was adhered to, and governed day-to-day living. 
Religion could better be described as ideology in the sense that – as with modern day Islam – religion dictated every aspect of daily life.   

Prehistoric Medicine


Medicine that predates written records, evolving with the emergence of modern hominids over two-million years ago. The study of prehistoric medicine is mainly dependent on sources such as skeletons, artefacts, and cave paintings, and draws heavily on anthropological studies of indigenous cultures in Asia, Australasia, Africa, and the Americas. Prehistoric people relied on a combination of religious beliefs and practical treatments made from local materials to treat their ailments. Their anatomical knowledge appeared to be very slight, and they believed that illnesses were caused by supernatural media, such as the gods or curses. Rational treatment was used only on obvious injuries; otherwise spiritual treatment was carried out by a shaman or medicine man, who received his medical ability through his relationship with the gods.




Discussing early records, S. H. Preston suggests that suggest that life expectancy from prehistoric times until 1400 or so was in the range of 20 – 30 years - Ch. 2 Samuel H. Preston pp. 30.

He goes on to say …’the most satisfactory collection of skeletal remains is drawn from the Maghreb peninsula (North Africa, between Egypt and the Atlantic) during the Neolithic period.  This population evidently had a life expectancy at birth of about 21 years.  Its age patterns of mortality were remarkably similar to that of modern populations at similar levels of mortality.

Whilst life expectancy was short, the likelihood of losing a child was equally gloomy with an average death rate before the age of five averaging around 500 in every thousand.

In an essay entitled, ‘The Decline of Childhood Mortality’ – (Kenneth Hill Ch. 3 pp.38). Hill admits the difficulties involved in retrieving accurate information from fossilized remains.  However, he goes on to discuss a more reliable method using the Theoretical Constraints of Population Dynamics method…‘Over the long haul of pre-recorded history, the human population survived but grew very slowly, with an average annual growth (allowing for periodic ups and downs) of less than one per thousand.  Births and deaths had to have been in very close balance, and the net reproduction rate (number of females surviving in the next generation to replace the mothers of one generation) must have averaged only very slightly over 1.0.  For this to have occurred, the requirements of population dynamics indicate that, over the long haul of prehistory, the probability of dying before the age of five for females was probably not lower than 440 per thousand live births and not higher than 600.  Risks to males would have been similar or higher.

The environment of nomadic hunter-gatherers peoples, whose homes were rude shelters in damp, dark inhospitable places, would be a world of mystery and a terrifying place where the prospect of often violent death accompanied each passing day.

Little wonder such people developed an inner desire for ‘something better’ – even if it was in an imaginary, heavenly or spiritual form of afterlife. 

In a sense, we here in Australia are fortunate to have a first-hand view of one of the few remaining ‘primitive religions’ to still exist to this day – namely, the Aboriginal Dream Time. 

Robyn Davidson, in her recent Quarterly Essay on nomads, sums it up beautifully in the following paragraphs:

‘One could say that the Dreaming is a spiritual realm which saturates the visible world with meaning; that it is the matrix of being; that it was the time of creation; that it is a parallel universe which may be contacted via the ritual performance of song, dance and painting; that it is a network of stories of heroes – the forerunners and creators of contemporary man.
During the creation period, the ancestral beings made journeys and performed deeds; they fought, loved, hunted, behaved badly or well, rather like the Greek gods, and where they camped or hurled spears or gave birth, tell-tale marks were left in the earth.  While creating this topography, they were morphing constantly from animal to human and back to animal, again rather like the Greeks.

They made separate countries, but interlaced them (related them) with their story tracks.  They created frameworks for kin relations. 

Many different ancestors created a country, by travelling across it and meeting each other.  In that way, a particular country is shared by all creatures who live there, their essences arising from the Dreaming, and returning to it. Some Dreamings crossed many countries, interacting with local ones as they went, and connecting places far from each other.  Thus the pulse of life spreads, blood-like, through the body of the continent – node/pathway, node/pathway – as far as, and sometimes into, the sea.  At the end of that epoch, exhausted by their work, they sank back into the ground at sacred sites, where their power remains in condensed forms.
It is not quite right, however, to say that the creation period is in the past, because it is a past that is eternal and therefore also present.  Ancestors sink back into, but also emerge from and pass through, sites.  In other words, an ancestor's journey, or story, became a place, and that place holds past, present, and future simultaneously.

For traditionally oriented Aboriginal people, the historical past lies a couple of generations back and always will.  The Dreaming encompasses and surrounds this time of living memory, which sinks into it.  Time sinks into place, into Country.  Each sacred site contains a potentially limitless supply of the particular species left there by an ancestor. 

But in order to ensure their continued generation, ceremonial action is required.  If this isn't done, or isn't done properly, that life-form will eventually disappear [a term Aboriginal people call ‘Looking after Country]’.  Children, too, are born from the ancestor's spirit which arises out of its place to impregnate a woman.  Such children belong to and have responsibility for that place, and will return to it after death, so that its life potential isn't dissipated.

Not only did the mythical ancestors give the world its shape, they imbued it with moral and social structures – handing down laws whereby all humans have intrinsic value and a share of goods.  Living by these laws invigorates the life-force surging and burgeoning through the land.  In fact, to sing a ritual song is to move that ancestor along through the land.  Earth is sacred, sentient stuff; it is not a counterpoint to heaven.  Heaven and earth are embedded together, on the same plane.  A country is saturated in consciousness.  It recognizes and responds to people.  It depends on people.

NO FIXED ADDRESS: Nomads and the Fate of the Planet - Robyn Davidson


The questions themselves – questions such as: why does the sun shine – why do we die – what is death – why do the seasons change – is there life after death (or why am I afraid of death) – all stem from a mind that is capable of being ‘self-aware’; a mind capable of communicating high level thoughts with other ‘like minds’.

The philosopher, Protagoras, 484 - 414 B.C. when asked about the existence of God replied that his faculties were too limited to take him to a conclusion on that matter and his life too short for the necessary search.  He later said that God existed for those who believed in God. (de Bono 1993 – pp.20)

In essence, the ‘requirement’ for a spiritual world offers an escape from the harsh world of reality.  It also offers a multitude of instant answers to questions beyond logical thought of the time.  The spiritual world fills many ‘perceived’ inner needs – not least amongst them the need to avoid or ‘survive’ death – or to have a meaningful spiritual existence after death.  It can be deduced that fear of death led to the creation of ‘another world’ – a world inhabited by beings or creatures capable of not only surviving death but of not even being subjected to the same physical cosmic strictures as mere flesh and blood.

That is on one level.  On another level entirely, the need for the human race to grasp at straws presents an opportunity for the smart mind to control the gullible mind.  With the emergence of self-awareness and the greater thinking power of the human brain – physical strength alone was no longer enough to make a leader.
  
Science Daily (Oct. 29, 2004), discusses how the fear of death affects people’s political choices.  Whilst this study is related to modern day political choices, I suggest the basic hypothesis applies equally to our prehistoric cousins: 
‘This research is based on the idea that reminders of death increase the need for psychological security and therefore the appeal of leaders who emphasize the greatness of the nation and a heroic victory over evil.

To test this hypothesis, Jeff Greenberg, a professor of psychology at the University Arizona in Tucson, Sheldon Solomon (Skidmore College) and Tom Pyszczynski, (University of Colorado, Colorado Springs) and their colleagues conducted an experiment that is scheduled to appear in the December 2004 issue of Psychological Science.

For their current research, the scientists asked students to think about their own death or a control topic and then read campaign statements of three hypothetical political candidates, each with a different leadership style: "charismatic" (i.e. those emphasizing greatness of the nation and a heroic victory over evil, as described above), task-oriented or relationship-oriented.  Following a reminder of death, there was almost an 800 percent increase in votes for the charismatic leader, but no increase for the two other candidates.

"At a theoretical level," the authors wrote, "this study adds to the large body of empirical evidence attesting to the pervasive influence of reminders of death on a wide range of human activities. 

These findings fit particularly well with prior studies showing how mortality salience leads people toward individuals, groups, and actions that can help enhance their self-esteem.  People want to identify with special, great things, and charismatic leaders typically offer the promise of just that.’

It is suggested that 1 in 10 people demonstrate leadership capabilities.  Whilst all cannot be leaders – many can be ‘leaders in their field’.  Opportunists abound throughout all cultures.  Often the most successful survivors are the best opportunists.  Those who see an opening then use it ruthlessly to further and improve their own life-style, and perhaps the life-style and chances for their own families for generations.

All organised religions had a beginning – originating with one man or woman; a person who sat amongst others – perhaps freezing and uncomfortable – a person who sat and studied others.  This was a person who had an idea and was prepared to offer that idea to others.  Maybe in some cases it was simply a thought that was spoken openly, rather than some great design or plan to take over the minds of others.  Perhaps more than one person was responsible for the further development of a belief.  Maybe, as often happens, the belief was linked to some quirk of nature – ‘we have done something wrong – it has rained non-stop for a month – the gods must be angry with us’. 

This type of thinking suggests immediately that if ‘we are good’, then ‘the gods will stop being angry with us and the rain will cease’.  The sun will reappear and all will be well.  So, if ‘we’ as a group do try to mend our ways – and magically the sun reappears – we are ‘obviously’ on to something big!   The same concept fits in with the trait humans have towards mass hysteria – and primitive mindlessness that is often more obvious amongst our primate relatives – with whom we sadly share many savage behaviours.

The idea might appear simplistic, but given that living conditions for many thousands of years, and indeed in many parts of the world to this day, are basic, to say the least, it is hardly surprising that the thought of being able to control one’s environment holds such great appeal.  Life is a truly hard road for many and at the end of that pain-filled road waits only death.  No wonder the human race looks for a better more appealing outcome.

Origin of Religion - Ancient Foundations
The origin of religion can generally be traced to the ancient Near East and classified in three basic categories: polytheistic, pantheistic and monotheistic. Atheism is really a modern belief (or non-belief) that resulted from the "Enlightenment" period of the 18th century.



The very life of the community depends upon observing the conventions of communication. The function of a religion is precisely to guarantee the whole system of convention, or the rules of thought and language, conduct, and role. For Judaism and Christianity, the idea of salvation is inseparable from the idea of belonging to a community of so-called chosen people, that is, the Church, considered as a body of members, or an assembly (Latin ecclesia), whether it be Israel or the communion of saints.

Religious salvation is basically the idea of incorporation in a divine community through conformity to the will of God. In the later phases of the Semitic tradition, salvation began to include the idea of survival beyond death, first through miraculous resurrection of the body and later, as a result of Greek influences, by virtue of the inherent immortality of the soul. Salvation, however, remained subordinate to and conditional upon membership in the divine community. After death, those who remain unincorporated are spiritual outcasts consigned, for example, to the Judaic Gehenna, the Christian Hell, or the Islamic Iblis. On the other hand, salvation beyond death is conceived of as being a state of the most intimate union with God, in which, however, the distinct personality of each member is preserved.

Thankfully, a growing number of people these days prefer their own version of the meaning of life, and the inevitability and finality of death.  Once the ties - and lies - of childhood religious brainwashing have been broken and fear of the great ‘unknown’ dispelled – it is quite possible for any man or woman to stand proudly and live life by their own unencumbered rules of decency.  When death approaches – that same person can meet death comfortable in the knowledge that they lived their lives as intellectually free and independent human beings - unbound by the fear of fanciful religious dogma.
