@Zetherin,
Zetherin - Regarding your post #100:

If I bend my legs and jump, am I not jumping, since I built up kinetic energy in my hamstrings and quads? Do we dismiss other things that happen, simply because they have a cause?
I am not denying that we make choices. We do things because we want to. And our wants are caused by our brain states, which in turn are caused by physical laws.
Imagine an extremely simplified "billiard-ball" model of the universe, disregading chaos and quantum effects, in which one event leads to another with total predictability. Then the sequence of all prior events would inevitably lead to a certain neurological configuration in your brain at a particular time. The combination of prior events and physical laws would then
make you think and act in a certain way at that time. From your conscious point of view, however, you would feel free.
Of course, the real universe is not like that; the unpredictability in chaos theory, and (perhaps) quantum randomness, must be taken into account. But since we agree (I think) that indeterminacy cannot of itself give rise to free will, we need only consider the
deterministic element of events for the purpose of the current argument.
So, in a universe where everything was totally predictable, there would be no room for real freedom because the course of all events would be fixed in advance. But, as noted above, unpredictability doesn't give rise to free will either. Either (a) you couldn't have done otherwise, because everything is predetermined, or (b) you could have done otherwise, but only as a result of chaos or randomness, for which you are not responsible.
I think we are in agreement as to what actually happens. We only disagree about the words we should use to describe it. This is understandable; when common words such as "free" and "compel" (which are perfectly clear in everyday usage) are used to discuss contentious philosophical issues, they can be imprecise and confusing.
