Do you have free will?

That’s an easy question. Of course you do.

Here’s a harder question: What is free will?

That’s where most of us get into trouble. Common sense tells us that we have free will, but doesn’t tell us what it is. We have only a vague idea of what it means to act freely.

And it’s a pretty important concept. If people can’t freely choose what they do, then they aren’t morally responsible for their actions. If we hold them responsible anyway, then we had no choice about it. Just like Alex in A Clockwork Orange, we are helpless automatons, not morally rational beings.

Our common-sense idea of free will is something like this: You go out for ice cream. You like chocolate and strawberry, but today you decide to get chocolate. You could have picked strawberry. Your will was free.

The problem is what we mean by “free.” Can a free choice be influenced by prior circumstances? You like chocolate and strawberry, so you choose one of them and ignore the vanilla. Could you have chosen the vanilla? Sure, but why would you? You felt like having chocolate ice cream.

For example, suppose when you go out for ice cream, your spouse teases you about always ordering chocolate. So you order strawberry — that is, unless you’re really annoyed, in which case you order Rocky Ripple. Your choice was still free, but both your taste preferences and your spouse caused you to make it a certain way.

That fits very well with how causation works. Events are almost never caused by a single thing. Normally, a whole context of causes makes things happen. In this case, the context included your spouse’s teasing, your ice cream preferences, and you. Which one of those things we choose to call “the cause” of your ice cream choice depends on the kind of story we’re telling and for what purpose. Since we’re talking about free will, in this discussion, you’re the cause. You made the choice.

What about Divine knowledge of the future? If God knows what we’re going to do, does it mean our actions are pre-determined, and therefore not free?

I’ll tell you a secret: It often occurs that months before I know what I’m going to do, my mother knows what I’m going to do. She doesn’t make me do it: I still choose freely. She just knows me very well, so she can predict what I’ll freely choose. However, even she doesn’t know me as well as God does.

God’s knowledge of the future doesn’t mean that our choices aren’t free. It only means that God knows us infinitely well, is outside of time, and therefore can “predict” our actions.
