Freewill Does Not Exist, Thus Reality is Deterministic

Here are my reasons to believe free will doesn't exist.

1. It has not been demonstrated that the law of cause and effect can be subverted. True, modern quantum speculations may suggest that it can be subverted; however, this is a lack of knowledge of "quantum reality," not proof of free will. Hidden variables don't prove free-will.

2. Knowledge is possible, even if ultimately limited to approximations. If free-will did exist, it would suggest that randomness is also possible. If reality were random, we wouldn't know anything since today's physical law could be tomorrow's fantasy. But since things are repeatable and demonstrable, i.e., not random, this is further proof that free will doesn't exist.
