Well I'm an atheist. But I'm saying that if we do believe in true free will, then we need some extra unknown "thing" to provide it, because the known ones don't appear to.
You is preaching to the converted... 😆
I agree that is exactly what I meant too.
No that's the thing about chaotic systems - while they can be modelled perfectly as an equation (or set of), an infinitesimal change in the initial conditions can deliver a huge difference in the system's behaviour.
So the system is modelled correctly and if you could perfectly reproduce the initial conditions you'd get the same result, but in reality that's not possible so the system can't be predicted accurately.
Also Lava lamps are much less complicated than humans, I bet we model them before us...
Nick I don't agree, free will to me is doing whatever you want. Wanting to quit work and ride all day has practical limits that I choose not to explore, much like doing an RKelly. The outcome have different levels of severity, but I cannot wish up an unlimited income on the spot, exactly as I can't wish myself invincible.
Apologies if it was too [i]preachy[/i]. I find it a really interesting discussion.

Hmm I wonder if we just dont have the ability yet, either in knowledge or computing power.
Which just goes to show, if we can't model two sticks, forget modelling wether I choose to wipe clockwise or anticlockwise after my coffee tomorrow.
Sorry Graham, I was just using you to make an excellent joke... (Atheism/preaching geddit?)
Also nick, I read the whole wikipedia page on free will earlier. It fits my definition exactly...
I wish we were in thepub. This is v interesting. Beer anyone?
Also thepurist you know? about numerical solutions right? The solution is an approximation.

Not sure about that. I spent a chunk of my third year at uni defining 0 and 1 from first principles and then proving that 0+1 = 1 and 1+1=2,so I'm on pretty firm ground there.
Also on the dual pendulum thing the computing power and knowledge to calculate it is pretty basic. For any given set of starting points you can accurately predict what happens to the system. It's perfectly predictable in theory but in real life half an atoms todger (*) of difference in the starting point can have a big impact on where it ends up.
(* or small measure of your choice)

Funnily enough last time I discussed this in earnest it was in the pub with an old uni mate and we were both smashed.

Yet people still claim that uni degrees are pointless? 😉

Oh, ok, I bow to your greater knowledge. 😆
defeying the laws of nature is Counterfactualism, and although has some common themes with determinism, it's not "free will" in the classic ancient Greek sense.
Counterfactualism is about perception, esse est pircipi all that stuff, if your world is just perception, is it real...Your brain sits in a dark room with no actual connection to the outside world, so it perceives everything second hand (so to speak).

Is that not a bit like saying the choice between life and death proves there's no free-will because no-one ever chooses to die?

No, sometimes people do choose to die, you however cannot choose to not die in a situation where the universe removes your chance of living. IE it aint your choice, even if you do not want to die, you still die. Therefore, no free will.

It is in the modern 5plusn8 sense... I do not have 100% free will, somethings will always happen, like death and taxes. I cannot decide not to have death, or taxes.

Can we have a demo please?
I am drinking cider tonight by the way, its nice, have a sip. The wife passes Waitrose in Horley on a daily basis and get me the boxed stuff. Left over from last weekends England rugby game.

Sort of. You may (or may not, after all the jury's still out) have free will over the decisions that you have available to you i.e. you can chose or not to jump from a cliff, the decision to then not hit the ground at 32ft/sec/sec is not yours to make, it will happen to you, and therefore outside of the discussion of free will.
With flying, again it's not a valid free will decision, you cannot choose to fly or not fly, as (in this world at least) as one of those options is not open to you (not a valid choice). You may (or may not) act within the boundaries of this physical world freely, what happens to you after you've made your last decision may be out of your hands, but as it's out of your immediate control cannot be said to be in the gift of your free will.
