This normally leaks away after a while. ok section 5. Entaglement *is* Observation. And whilst a naive view is that observation is easy to understood (even though it's not explained exactly what it is) and entanglement is really hard. They are the same thing. So there are no particles only probability waves. Hence no objects. And no randomness. "randomness is not an essential cornerstone of quantum measurement but rather an illusion created by it."

So what *they* mean (not you or other compatibilists) when they say "free will" is something involving a soul, something that is *not* determined. Determined means precisely "not free." What you and other compatibilists mean by "free will" is, as Ron pointed out, "a very convincing illusion of free will that is really deterministic." This is emphatically *not* what Roman Catholics, for example, believe. warmest regards, Ralph -- Raffael Cavallaro

Compare the numbers of Calvinists in this world, and the number of Roman Catholics for example; we are talking about what "most people" believe, not what one small sect believes. The Calvinist notion of predestination is so noteworthy precisely because it is as odds with traditional christian doctrine. warmest regards, Ralph -- Raffael Cavallaro

What is also interesting is that nobody can seem to agree on what "free will" means. Pascal, for example, says that free will deals with the amount of control one agent has on the will of another agent. By this, he doesn't mean external control, but internal control, using the analogy of changing a computer's state between "clock cycles". Ron, I think, defines free will in terms of information assymetry between two agents. And, if I read you correctly, you define it in terms of information assymetry between the agent itself, i.e., the agent is free since the agent doesn't necessarily know what he/she/it will choose. Now, if I understand both you and Ron correctly, it seems odd to define freedom in terms of knowledge; especially since theologians have shown that foreknowledge is not predestination; i.e. knowledge is not control. I can understand why theists would want to grapple with the issue of the freedom of the will. What I don't understand is why non-theists even care. Shouldn't it be a non-issue? The will is just another phenomena like the color of the sky. Freedom, or the lack thereof, shouldn't enter the picture. Or am I missing something?

I'm not Lutheran, so I hesitate speaking for them, but they, like Calvinists, don't subscribe to free will, either. In any case, the arguments for free will in a theological sense typically come down to two issues: 1) The desire to be free; i.e. not under the control of someone, or Someone, else. As the poem Invictus says, "I am the master of my fate: I am the captain of my soul." 2) The notion that moral responsibility requires moral freedom. It isn't hard to see how the first arises; our wetware is geared toward self. But where in the world does #2 come from? How can that possibly be shown to be true? |
