Aneuroscientist says free will doesn’t exist.
A philosopher says it does.
Both are persuasive. Both are serious.
And both, in their own way, seem right.
That should make us suspicious.
When two intelligent people appear to be arguing in opposite directions, and both make sense, it often means they are not answering the same question.
That, I think, is what has happened in the free will debate.
For years, the argument has been framed as a clash between two positions.
Everything you do is caused.
By biology, upbringing, environment, and prior events stretching back before your birth
Or,
Despite all of that, you still choose freely.
But those are not actually parallel claims.
When Robert Sapolsky says free will doesn’t exist, he is talking about causation.
Every thought, impulse, preference, and decision has a prior.
Your brain does not step outside the universe to make a choice.
It operates within a chain of events.
On that point, he is right.
When Daniel Dennett defends free will, he is talking about something else.
He is talking about what it is like to be a creature capable of reflection:
to hesitate, to reconsider, to weigh one impulse against another, to change course.
On that point, he is right too.
So the old argument may be stuck because it keeps treating a single phrase — free will — as if it refers to a single thing.
It doesn’t.
One side is describing the structure of reality.
The other is describing the lived experience of being a certain kind of organism inside that reality.
And once you see that, the puzzle changes.
Sometimes you can catch a thought.
Sometimes you can’t.
That difference…
