I don't believe anyone can have free will in the sense that they can make decisions that were not effected 100% by external cause and effect, cause and effect.. and so on. If i choose to eat a chocolate bar.. there are reasons that i would do so.. i didn't pull the choice out of nowhere.. i was hungry perhaps.. i didnt feel like something savoury.. i had money... there was a shop nearby.. and so on.. sort of like the butterfly effect (where a butterfly flapping its wings could be enough to mean that there will be a hurricane on the otherside of the world) every single cause and effect between every single atom of the universe.. effects how us as humans think.. and the suposedly 'free choices' we make.. If we, as humans are purely made up of matter within this universe.. (as apossed to having an imaterial soul of some kind) then just as everything around us is subject to the laws of physics etc.. our bodies and minds are also completely subject to the laws of physics.. and so we have no real control over what we do... as what we do is determined by what effects us .. and that effect is in turn affected by what effected it.. and so on. Therefore, to have free will we must have souls/spirits/minds of some sort that do not exist in a material world (meaning they would not have to be subject to any kind of laws..).. however, the thought of any kind of realm that is not material and cannot be subject to the laws of physics is something that is logicaly impossible... (in my opinion.. and many others) and would be something that humans could not comprehend... therefore.. it is 'logical' (logic being something that we have to use.. if we are to even try and obtain answers from life) to believe that there is no such thing as a non-material mind and in turn to not believe in free will... If that did not make sense to you then maybe this will explain it in more depth: http://en.wikipedia.org/wiki/determinism and yes this does mean that there can't really be such a thing as blame.. and that people who commit crimes coudln't have done otherwise.. and also that people who punish people who commit crimes coudln't have done otherwise.. and that everything that has hapened was destined to happen and that whatever happens in the future woudln't have hapened any other way.. These sound like negative points... but they are a necessity that comes with holding the opinion that 'we don't have free will' to be logical anyway.. thats my opinion on the matter.. what do you guys think?
