apeiron said:My basic point here is again that thinking about complexity in terms of simplicity is the source of most modern philosophical errors.
To see how "freewill" (anticipation, autonomy, etc) can arise in complex adaptive systems, it is better to start from simple examples of complexity (ie: simple forms of life), rather than simple examples of simplicity (ie: Newtonian deterministic mechanics).
One really cute little example is the way a flagella-driven bacterium like E. coli makes intelligent choices.
E. coli swims along, driven by the anti-clockwise cork-screw paddling of its flagella, seeking food. While spinning anti-clockwise, the flagella are all tangled together and the bacterium swims straight.
Covering its surface are receptors that can scent sugars and amino acids. While the receptors are picking up traces of food, the instruction to the flagella is to keep rotating anti-clockwise. But if the concentrations start to fall off, then the flagella are told to reverse. This then untangles the flagella and sends E. coli into a random tumbling spin until the scent begins to pick up again, at which point straight-line swimming can resume towards the source of the food.
So we have here a beautifully simple feedback mechanism. And no philosophical problem at all about how a bacterium switches from a determined, directed, action to an undetermined, randomly exploratory, undirected one.
Extract the principles, scale them up to more complex animals like cats and humans, and we have naturalistic explanations of "freewill".
You won't find anything sensible to latch on to while you stay stuck down at the level of atoms and wavefunctions (or binary computer circuits and information). But a training in biology just makes freewill a non-issue philosophically. There is still the complexity of brains to explain, but no big deal about animals making intelligent choices as a result of fundamental asymmetries (dichotomies) embedded in their design.
Brains work one way when they are smoothly anticipating the world, then switch to a different approach when they encounter errors or suprises. There does not have to be a little homunculus compartment in the brain that does the chosing. The world is always out there to drive things along.
What you described in these microscopic organisms was not freewill but rather a command-protocol that causes them to switch algorithms when sensory data drops below a certain threshold. When does the organism make a concerted random choice to do anything in your scenario?
Freewill is neither determined by a particular cue, nor completely random. It is a choice made at a particular moment based on chosen criteria. It is a modus operandi of human consciousness in a sense. I don't know whether it could be observed except from a first-person perspective.
I will only add to this that I don't think freewill is limited to human cognition. I suspect that the cat goes through a process of "what should I do now?" . . . "hmmm, I guess I'll go ahead and meow to go inside, get food, etc." I don't think it is constantly reacting reflexively to biological drives. I could be wrong, though. How could I know?
I do know, however, that I was about to post this response and then suddenly went ahead and added this concluding paragraph. I could have gone ahead and posted it without doing that. I could have even stopped in the middle of a
