I understand Bryan greens analogy about the limited freedom that we have compared to inanimate objects like rocks.  That human behavior is more complex than rocks is understood. However having treated many humans for substance-abuse behaviors, and crises of existentialism, this news is no more uplifting news than just stating that we do not have free will. I can predictably tell you with hard statistics, what percentage of people WILL develop depression anxiety, loss of hope, and ultimately substance-abuse and death.  These are real numbers that carry forward into reality prospectively, and predictably.  While it is true that I cannot predict with certainty which individual will develop substance-abuse and die from that condition, I can without a doubt, predict for you the number of people who will see this fate reliably. That is not free will, because that number does not change No matter what those individual people hope and think for themselves in their own individual lives.  It's equivalant to a teacher telling their students, that all of them have the free will to get straight A's.  But the results at the end of the year, are that the bell curve remains distributed the same as it always has.,(reply>), WRONG !!! FREE WILL DOESNT EXIST !!!!,(reply>), The analogy to rocks is interesting. Basically the argument is that the behavior of rocks does not change unpredictably, therefore they do not have free will.  Dinosaur and reptile behavior is more predictable than "higher animals" and therefore reptiles have a less rich conscious experience compared to humans... Well maybe that's true.  But my assertion is that human group behaviors, do not change unpredictably. The statistics show this fact, and epidemiology is only useful if the findings are generalizable to predict future occurrences. Therefore group behavior does not have freedom of will, and it is not influenced by individual free will.  If group behavior does not have unpredictable results, and individual behavior which helps constitute the groups behavior, are inconsequential, then how much free will does the individual actually have, despite feeling like they are more unpredictable than a rock or reptile?
