Excerpt from The Fabric Of The Cosmos by Brian Greene:

Whereas human intuition, and its embodiment in classical physics, envision a reality in which things are definitely one way or another, quantum mechanics describes a reality in which things sometime hover in a haze of being partly one way and partly another. Things become definite only when a suitable observation forces them to relinquish quantum possibilities and settle on a specific outcome. The outcome that's realized, though, cannot be predicted-we can predict only the odds that things will turn out one way or another.

Freedom is built into the universe.
