I think the awareness of moral choice introduces the only genuinely "chaotic" behavior that has been observed in the universe (All other such claims are actually just acknowledgments of processes with too many variables for us to quantitatively predict). While the neurons certainly fire in a way that is statistically reasonable, I believe humans have a non tangible soul with veto power over instinct and biology.
@Ventifact and Rasmurr
Very much agreed, except for Rasmurr staying that we couldn't judge people on moral grounds. If it was generally scripted that human life is deterministic, the definition of moral would change to work in that system as it has worked in our current system.
Those initial conditions are still factors, and yes, chaos theory is built upon the premise that initial conditions, changed slightly, give a different result, but it still gives a singular result, and since we can't change the initial conditions in our universe, it is deterministic. The reason that chaos matters is not because it creates randomness, it creates a seeming randomness because humans have finite knowledge about these systems.
Yes, in multiverse theory there are infinitely many universes, infinitely many initial conditions, but we still inhabit only one. These other universes become apparent because of their changes over time (they don't exactly "split off, asdfadf, if that's your real name), but even if we can't observe them, it doesn't mean that we can't know that we inhabit one, which has a predetermined outcome. If it doesn't have a finite end, since now there's evidence that our universe may not have one, but it still doesn't mean that the path will change.
I believe that people are being hung up on the fact that we can't know our outcome, but that doesn't mean that we don't have an outcome based on our initial conditions. We don't need to know what it is in order to know that there is one, dvds only one
So many people today don't want to take responsibility for their actions. See law suits about pouring hot coffee on your own lap and getting hurt while robbing someone. So many people want to believe that what they do doesn't matter. See universe-splits-when-anyone-makes-a-choice theory. I wonder why this is.
The point most of these posts miss is that the chemistry of the brain (human and animal) has become complex enough to achieve consciousness. All this means is that it is able to influence its own chemistry.
Yes, the chemistry of the brain controls what people do...AND free will (their consciousness) is able to control their brain chemistry. A person's actions are a result of the chemistry of their brain, and that same chemistry can change itself...so yes, you can hold a person responsible for the chemistry of their brain.
