Okay, who did it? Who went and angered the Gnomes of Zurich? Who screwed the dwarves out of their rightful tribute? Who went and annoyed the boys at Gringotts? I know somebody did, because otherwise we wouldn't be in this mess.
No, really we wouldn't. Of course, it always happens this way – humans get greedy for gold and it all goes downhill from there. All you have to do is keep your head down and don't go near them. Instead, like magpies in their black and charcoal plumage, the suits decided to plunder the shiny realm, help themselves to the pots of gold.
Look where that has got us – another financial meltdown. Stocks plummeting, doom upon the horizon. Some part of me wouldn't be surprised if Ragnarok was around the corner, except of course it always is – just at the corner of your eye, but that's another story.
Economics – or as Terry Pratchett puts it 'reflected-sound-of-underground-spirits' a.k.a. Echo-gnome-ics – purports to be the art of dealing with such things. But as anybody who understands the myth of Echo will tell you, there's a bit of a problem.
Echo was doomed to repeat the words of others, her voice taken away by Hera in revenge for consorting with Zeus. Essentially, her communication was reduced to that of a cargo cult – mimicking and repeating sound with little hope of understanding.
Now, notwithstanding the fact that all communication is a bit like this, economics is about appearance. Those bankers and stockbrokers are doing the equivalent of listening to the voices of the gnomes and other chthonic spirits, echoing down mining tunnels and fissures in the Earth. They interpret echoes and make decisions based upon them – an entirely virtual construction based off second or third order perceptions.
It's no wonder really, considering that Paracelsus states that gnomes are capable of passing through solid rock as easily as humans pass through air, so for those of you who enjoy Harry Potter it might help to envisage them as being masters of the Apparate spell.
As apparitions, their substance is by nature more loosely bound than those humans – their outline lest fixed and form more fluid. It makes sense then, that they are masters of the physical, because their ability to modulate matter is a massive engineering boon. This is why in Norse myth, the dwarves are the creatures that create the weapons and tools of the very gods themselves.
This excerpt from Neil Gaiman's award-winning novella The Truth is a Cave in the Black Mountains, which is available in full here, illustrates this really quite well:
