These 3 paragraphs from the link above them all struck me more than anything. I think it's saying that the future is open to our alterations, but once acted upon, the initial choices remain set. In quantum mechanics, a similar spectrum of possibilities exists, but it becomes a definitive result upon observations, chosen out of many other factors that, under different chance results would have unfolded towards another destination.Originally Posted by Montalk
All future transformations are contingent with how the present shapes out, and free will gives us the power to direct its ultimate course. Free will, assuming we actually have it would be the random variable and the unknown factor which determines the future. Paradoxically, we could say that the indeterminate nature of free will can command what comes to happen and, with sufficient force of will could theoretically by the guidance of our determination make any event imminent.
Perhaps this is the prime cause for all actions that happen everywhere, that they are moved by some kind of mind, maybe even by minds above our own. Under a system along these lines, any vision could become real, and the present would have all promise for those who seize it with the right tenacity to become anything. Ultimately, my personal conclusion is that everything is determined by free will.
Stephen Hawking also has good thoughts on this question, as depicted in the below videos:
