Metaphysical libertarianism. Yeah, by definition, that's not compatible with the view that everything is determined by physical processes. This is just people freaking out over determinism. I kind of see why. "I am a physical process" sounds like "I am controlled by fate and my choices are pointless". But a person is a process that can't see the future, and a process that experiments and discovers things. Choices are the deterministic process: the person determines things. I could repeat this several times in different words but I'd just be trying to placate a kind of paranoia that happens when people realise they're physical.

Why are you framing this in terms of placating my paranoia? I have no objection to my lack of free will, it does not bother me. It makes me more empathetic to recognize that others lack it as well.

So, let me get this straight:

You think metaphysical libertarianism is meaningful ("meaningful free will"),

You also think it's false (why, if it's meaningful?),

You aren't bothered by this,

And something vague about empathy. Is that like "it's not your fault, you had no free will"? So about blame?

But the function of blame is to manipulate people's choices, and that works even when we acknowledge that the choices result from physical processes.

> You think metaphysical libertarianism is meaningful ("meaningful free will"),

> You also think it's false (why, if it's meaningful?),

Why would we expect any coherent phrase like "metaphysical libertarianism" to be true simply because it contains meaning?
