If I hallucinate prismatic shapes overlaying everything, it does not follow that there is some non-physical phenomenon which is responsible.

“It is obvious that the world is covered in prisms. It’s obvious that those prisms don’t fit in my eyeballs, therefore the entire scientific edifice is mistaken and we need a metaphysical explanation for my experience.”

Comparing free will to a hallucination isn’t helpful because everyone knows the difference and has experienced them.

No, actually, that’s the point they allude to: that free will might be an illusion, a hallucination.

No one denies the lived experience of free will, the inquiry into it asks if we can quantify that qualia without resorting to complete determinism.

If we can’t, it is perhaps an illusion. There is ample precedent for lived experience being an illusory lie told to our minds by our brains - visual hallucinations are the closest example to hand.

[mensetmanusman]

Beings without free will can’t prove anything though since the verbs available to a being without free will is an empty set, and passive descriptions are more apt.

[w0de0]

I don’t think free will and autonomous action as described by a verb are equivalent.
