AB,
I have not read the book, but I did view some url links you gave some time ago on the subject of emergent properties.
A good start. I hope you found them helpful.
Emergent properties are simply the observed natural consequences of events.
Sort of: “natural consequences of events” is a loose way of putting it, and they don’t have to be “observed” to occur nonetheless, but ok…
Any perceived complexity or specific functionality must be derived from the cause of these events.
“Perceived” or not, it’s “derived from” simpler components yes. The point though is that those simpler components need have no awareness at all of the complexity that ensues because of their existence – the complexity is in other words bottom up, not top down.
If a set of balls are correctly racked up for a game of snooker, the cause will have originated from the free will of the person setting them up.
You’re falling back into your mistake about “free” will again I fear, but if they are “racked up” then someone will have done it. The point though of the motorised snooker balls example is that there’s no necessity to programme them with the instruction “arrange yourself racked up for a game of snooker” – only very basic instructions are needed (“turn 15 degrees right when you hit a red ball”, “wait five seconds when you hit a blue ball” etc) and, if you wait long enough, at some point you’ll find that they're arranged ready for a game of snooker with no top down instruction whatever to do so.
The cause of the perceived functionality in an ant colony will be derived from ant behaviour resulting from many years of evolutionary development - and this will be sourced in the DNA of the ants.
Again, the point is there’s nothing in ant DNA that says “build a nest”, “remove the dead ants” etc (what language would the DNA even use to do that?). Instead all it has is very simple instructions – “if you find food, leave a pheromone trail to it” etc – yet from those very simple instructions astonishingly complex societies and behaviours emerge with no top down designer of any sort needed to make it so.
Your suggestion about evolution is though relevant to the extent that that’s what distinguishes ants from snooker balls for this purpose – ant behaviour is
adaptively emergent, whereas snooker balls would be non-adaptively emergent because non-“successful” snooker balls don’t exit the genome while the others thrive.
The cause of a perceived snowflake pattern will be derived from the natural behaviour of ice crystals.
Perceived or not perceived, the pattern will be there nonetheless but ok…
So an emergent property can have different causes, and to me it is not a valid explanation for human awareness.
Aw no! You were actually doing quite well there, and then blammo – straight back in with an argument from your personal incredulity.
What a shame.
The point is that emergence is a well-understood phenomenon that very well explains how complex results can come from very simple constituent parts, and there’s no reason at all just to assume that consciousness isn’t another example of that phenomenon. That “to you” it’s not a valid explanation is a matter for you, but it
is a valid explanation to those who actually study these things. Why would you think that that consciousness should arbitrarily be excluded from the principle, whereas other highly complex outcomes should not be if not for, "that looks hard, therefore God"?
