Free Will Debate

[Anomalocaris]

the question seems to me to be, can something be sufficiently different in your brain to have caused you to make different decision, without that difference being directly traceably to an earlier difference that had already existed outside your brain? 

if not, then no decision really originated in your brain.   it is just first perceived by you as a difference in your brain.

Why would that be desirable? I *want* my decisions to be based on my experiences (outside events affecting me). It would be exceedingly strange if they were not.

Most likely, that small difference in my brain that 'decided' is the result great number of previous events, both inside and outside of my brain. No single one of them would be enough for a different decision, most likely. Those previous influences had to come together to affect the activity of my brain for the decision to happen.

In other words, both external and internal events affect my decisions. Duh.

I make no judgements regarding whether that is desirable.  I only ask whether that could be true.

regarding both external and internal events affect your decision. does the doc-called internal event truly have any significant freedom to transpire differently resulting in different decisions if all external events remain the same? if not, then there is no real internal events, only intermediate effects of external events.

it is possible the brain magnifies the chaotic nature of how decision responds to subtle changes to external events. but other things can also magnify the chaotic nature of how effects of external events impinges on your brain. Also, a macroscopic chaotic system is still in most cases essentially deterministic.
