Instead, determinism is about whether the universe's course is preset, predetermined, without any random or outside influences that can change the future. If the particles subject to HUP have actual, precise values, then it's possible that the end results of their interactions are completely fixed, and the universe is just one big machine.. and free will is an illusion.
Free Will Definitons:
The power of making free choices unconstrained by external agencies...
The partial freedom of the agent, in acts of conscious choice, from the determining compulsion of heredity, environment and circumstance...
Free will is NOT about the fact that every element in the universe is determined to follow a specific path.
Free will IS about making decisions that run contrary to EXTERNAL compulsions on the individual agent.
If you are hungry, and you choose not to eat a meal placed in front of you, you have exercised free will.
Your DNA, curcumstances, and environment compel you to consume the meal, yet you resist.
The reason you resist may have been preordained (the particular chemical and neurological balance in your brain leads you to make a decision).
The INTERNAL mechanisms that allow you to make a choice may in fact be forced down a deterministic path.
But the fact that the decision was made despite EXTERNAL forces is what defines free will, and is not at all incompatible with a completely deterministic universe.
