The universe is not the only way it can be... But the way it is -- features (the potential for and) the realisation of natural generation of intelligent... self aware individuals who are so caut up in the illusion... that most of 'em still believe that will is free.!!! An even tho the underlying mechanism apears to be random... they want to believe that this randomness somehow leads to free will.!!! Just to clarify: determinism is more than just cause and effect, but the principle that if you rewound time and pressed play again then everything would come out in exactly the same way. It is a case of X always leading to Y always leading to Z etc: if you have the same inputs then you always get the same output. Indeterminism is still a matter of cause and effect (although could allow for the uncaused) but where the same inputs can lead to different outputs. Randomness in the output, e.g. within a probability function, would make the universe indeterministic. My take is that the same inputs lead to the same probability function of outputs, but the specific output is random in line with that function. So if you rewound the universe I think it would have almost zero chance of being exactly the same as it is now. It might be close, depending on the cumulative probability functions, but it would also depend on the level of chaos in the system (chaos being the sensitivity of the ouput to the starting conditions). Hence my slight amendment above. Please Register or Log in to view the hidden image!
