I have some trouble with the idea of free will. It seems rather essential for explaining evil and yet, the more I think about it and discuss it the less robust the “we have free will” arguments seem. Here are three of the more compelling arguments against it from three different fields. I’d like to hear some replies.
Philosophy:
Here is a classic that is stronger than most people give it credit for
- In order for an action to be free, there needs to be a choice of possible actions.
- If God knows I will eat toast for breakfast tomorrow then I must eat toast tomorrow since God is never wrong.
- If I must eat toast tomorrow, then I have no choice whether or not I will eat toast.
Therefore: the toast eating action isn’t free.
Nobody said you “must” eat toast tomorrow. You can choose what you want to eat, with the limitation that it must be an item you already have in your house, or that you can buy it on the way to work. It’s your choice, and even if God sees you eating toast tomorrow, He
won’t make you do so.
Physics:
This one won’t have premises because I don’t know the math well enough, but I have it on good authority that if general relativity is actually the case, then all of our actions must already exist “out there” and someone could see my future given the right circumstances. The idea is that right now, what counts as the present for me exists as the past for someone if they were significantly far away from me. In the same way, what exists as my present would also be someone else future. All of the events that will ever happen already exist depending on where you are in the universe. I don’t think it matters much that no one, as far as we know, is over there. Mathematically it all exists already. Here is a youtube clip that explains it better than me.
Watching somebody’s past actions is hardly the same thing as making them act that way. You just happened to observe them doing so, but it was still their choice.
Biology:
Using functional MRI machines doctors can predict the choice a subject will make well prior to the subject being conscious of having made a choice. They hook you up to the machine and say “press either the left or right button” and before you are aware of having made a choice they know what you will choose. Now, one might easily say that subconscious decisions are still decisions, but morally and even legally I don’t think that we agree with that. I am not held responsible for things I have no control over. Presumably we have no control over our subconscious, which is why we dream weird things.
Assuming doctors can see you making a simple choice in response to a question, all they are doing is watching
you make the choice, by watching your brain waves. Since the brain waves precede your choice, they’ve got a very small drop on you.
The question of free will versus predestination is an interesting one, and I think they both operate to some extent. I’ve got a personal reason for saying this, as I claim my father appeared in my room the night he died. He’d been very cruel, and the episode started with an apology from him, and a terriftying scream just before he disappeared again.
But during the proceedings, he exclaimed at one point, “I always was doomed! I didn’t really have any choice!” I argued back (even though I was an atheist at the time, plus I was wondering just what the hell was going on here at the same time), saying “That can’t be right!”
He replied, “Oh, it’s right all right! You can see that from here!”
But later in the same exchange he admitted “I was WILLING!” (to act in the cruel, bad tempered, stupid, vindictive way that condemned him,
and to keep it up for twenty five years non-stop). My old pastor remarked, “It’s almost as though he wrote a policy statement, that his mission in life was to wreck your life!”. He may have been foreseen doing it, but he was quite willing to do so.
So predestination may be correct in the sense God can see what’s going to happen, and what we’ll do. But you can bet your bottom dollar we’ll make the choices that lead us to heaven or hell. We’ll be “willing” to quote my father.
