@tomr,
Quote:I will admit that considering the ways neurotransmitters can affect the signals between neurons is significant. But the unpredictability/complexity of a system does not make it free. Even chemical interactions are electrical in nature and if you consider them quantum mechanical then they are Random. I still see nothing that gets us free will in this. Where is the free will coming from?
I believe there are many reasons why such a system would have some randomness of outcome, which in effect would get rid of the determinist distraction.
Randomness does not make the system free. What makes it free would be, IMHO, that it serves to build a virtual world, our mental world, conscient and inconscient, in which images, sensations, ideas and desires collide and interact to produce decisions. This virtual 'world of ideas' is real, but on another plane of reality than the underlying circuitery supporting it, it's on the mental or knowledge plane. It's our mental world, the world you and I live in. It's us. Therefore we can be certain it exists.
This virtual world is constructed for a reason: so that the subject can model the real world, and play with different scenarios, different actions available and their likely outcome. That's why it comes complete with a 3D euclidian space into which senses's feed are uploaded, pattern reognition software, intuitive sense of time, motion, accelaration, short-term and long-term memory, and a sense of agency.
The question is: is this sense of agency real? I believe it is. Entities within that virtual world are operative, they can cause an effect. The fact is that you can chose to raise your arm. Therefore an idea can result in, be translated in a series of neuronal signals to your arm and make it move.
