Your comment fxcking rocks. It's not about making sense, it's about the process of engaging your mind, which you have done. Kudos! Statistically speaking that makes you a modern day superhero! I'm having difficulty connecting the dots that the randomness inherent to quantum mechanics is necessarily interdependent on whatever defines consciousness, but I also don't believe there needs to be a "ghost in the machine" to explain consciousness--it's satisfying enough to me that a sufficiently complex system can and will produce emergent phenomena that appear to exceed the sum of the parts. (I could totally be wrong, I'm a fxcking articulate layman.) Regardless of how you arrived there, the supposition that "self-will" is rooted in the very randomness over which it grants us a measure of control is godamed glorious.
And you're absolutely right that quantum mechanics is an enigma--even to the foremost "experts" in the field. That point is precisely what makes any claim that determinism is provable, much less proven, so stupefyingly preposterous. Yet many people claim free-will is a myth, discussion over, case closed, deal with it, and then point to a chain of flawed, circular logic to prove their assertion, all the while acting as though quantum mechanics is either fully understood or of no relevance to their argument. Meh, even the scientific-minded can be irrational and myopic.
