That would only be true if behavior or thought were independent from brain activity, which they are not. So it is not a separate issue, people simply compartmentalize free will in their brains from logic to prevent reaching inevitable if uncomfortable conclusions. | ||

It's stochastic. Could you explain why it's stochastic? So far the only factor making it non-deterministic that I've encountered is quantum mechanics. | ||

I don't know - ask an intro to philosophy professor. | ||

No, it will always remain a philosophical issue. Science will never prove either determinism or free will, nor will it "prove" anything in fact. | ||

If only people would have thought like this originally there would have been no need for pythagoras, plato and aristotle and all that nonsense. | ||

If OP or any other person has any doubts is becouse they find reality too complicated to understand and gave up on science but still need an answer. The answer is obviously no, but if that doesn't make you happy or satisfied you can make up something like a soul or whatever you can think of. The problem with this is that the initial stupidity has not disappeared and it will manifest itself again by acusing gingers of not having a soul ( genetics too hard for me >.< god may have punished you haha! ) or burning alive women becouse they are "witches". Don't get out of touch with reality OP, or we'll be killing ourselves becouse that guy said that he knew a guy who saw a guy who said there's a reason for everything and is too complicated for you to understand so you must do just what he tells you. | ||

Brownian motion, the mechanism through which neurotransmitters diffuse through the synaptic cleft is a stochastic process. Since neurotransmitter binding controls the ratio of excitatory and inhibitory postsynaptic potentials, whether or not EPSPs and IPSPs sum up to generate action potentials, and the timing and frequency of action potentials all depend on stochastic processes. The difference between pulling the trigger or putting down the gun can be the difference between whether one neuron's neurotransmitters got there first or not. | ||

You are aware that we know laughably little about how the brain works and how it influences thought and behavior, yes? It is incredibly pretentious and arrogant to reach such a far-reaching conclusion from so little evidence. | ||

Realize how important this lack of surety is, it lies at the base of the reason why interpretation of diagnostics of any kind are fundamentally limited. | ||

No scientist uses terms of certainty when discussing random processes. That would be stupid. That doesn't mean that the processes that science describe are not correct. | ||

I would agree that a certain, perhaps large, amount of it is deterministic, but there can be wide variation. I would use reproduction as a parallel, given that is entirely a chemical process. We have laws of inheritance and can make broad predictions about a child from its parents, but end results are not necessarily inevitable and there are plenty of things where things may be unpredictably different. | ||
