Spoof,
My advice to you is that same as that I gave to Sriram earlier on: try reading Steven Johnson’s “Emergence: The Connected Lives of Ants, Brains, Cities and Software”.
Seriously - it’s an entertaining read anyway, and it’ll also explain why your understanding of emergence is wrong. In short, there’s no Hey Presto! about it, for the same reason that termites don't need theodolites and blueprints (let alone a Hey Presto!) to build their mounds. I'll grant you that it's counter-intuitive to start with, but you'll get the hang of it I'm sure.
I don't believe I gave a definition of emergence Hillside. Hopefully your recommended reading is not a rehash of reduction gussying up the power of the previous level and getting emergence merely by piling on more atoms, molecules or even neurons.
If you haven't read that link that Bluehillside provided, you can save yourself some time as all of the examples used illustrate the above. The conclusion? Complexity can arise from something less complex.
Extrapolating from this is what causes the problem, because the real issue to address is that of
gain, not increase. A gain cannot come from what is already present, yet it appears that some are wanting to use the idea of
emergence to get round this problem.
Take termite mounds. They are made from what is already present and the ability to form them is already present! Furthermore, work is done to create them, so there is no
something from nothing problem. What happens inevitably is that there is an extrapolation from this to claim that the termites who create the mounds come from something simpler than termites, which in turn came from something simpler than itself, which in turn came from something simpler than itself, ...
In the beginning, nothing caused something and the something went on to self-enhance itselfIllustrating in another way: Let’s say that all life was wiped out on earth and there were aliens from another planet that came to earth and saw these termite mounds. One of the aliens says, “Those mounds were created”. Another says, “You can’t say that, because then you will have to say, who created that which created the mounds, and you’ll get an infinite regression”. Another says, “Yeah, you’ll also have the problem that postulating some indigenous life-form is an unfalsifiable conjecture”. They then come up with an explanation to say that perhaps the mounds were formed over a long period of time due to unknown natural (non-animal) causes.
The whole thing is
counter-intuitive because it is contradicted by what can be observed! Like Richard Dawkins, who has to use terms like
the ‘illusion of design’ to get round problems, the explanation exists
despite the evidence, not because of it.
