Think about how it happens.
There’s some electrical activity in your brain.
Your neurons fire. They send a signal down into your nervous system.
It passes along down into your muscle fibers.
They twitch!…
You might, say, reach out your arm.
Looks like it’s a free action on your part,
But every one of those… Every part of that process…
Is actually governed by physical law:
Chemical laws, electrical laws and so on.
