SENTIENCE

Mmkay, is sentience/consiousness/ect quantum, chemical/electrical, or SPIRITUALLL?

You can't prove scientifically that the universe is deterministic though, due to the heisenburg uncertainty principle. All Penrose is saying is that because we cannot predict everything absolutely we cannot say for certain whether the universe is deterministic or not and thus cannot say whether we have free will or not.

Also, can you stop being irrationally hostile to the idea of free will, it certainly seems that way, I exist, perceive, think and can choose to do what I want. If you exist as a sentient being the evidence is right there. This evidence disproves the idea that we are all robots with as much sentience as a rock, or that inanimate objects are our equals.
