I think the idea is that the relationship is between physical and mental states or events, rather than brain states or events, which are physical.Gary Childress wrote: ↑Sat Jul 13, 2024 1:14 pmI would say that changes in body states are also accompanied by changes in brain states.

You as an alive person with self consciousness is a case and example of Supervenience at work.
Here is AI[wR]'s views:
Discuss??ChatGpt wrote:... the emergence of consciousness from a physical body can be regarded as a case of supervenience. In philosophy, supervenience refers to a relationship between two sets of properties such that if there is a change in the supervenient properties, there must be a corresponding change in the subvenient properties. Applied to the mind-body problem, this means that mental states (consciousness) supervene on physical states (the brain and body).
In this context:
Subvenient properties are the physical properties of the brain and nervous system, including neurons, synapses, and their complex interactions.
Supervenient properties are the mental states and conscious experiences that emerge from these physical properties.
The principle of supervenience implies that any change in mental states must be accompanied by a change in the physical states of the brain.
However, it does not necessarily mean that the relationship between the two is causal or reducible. It allows for the possibility that mental states are dependent on but not fully explainable by physical states, aligning with certain non-reductive physicalist or emergentist perspectives in philosophy of mind.

But I agree with your point about sub- and supervenience. If there's complete simultaneity, then why give them different labels, which suggests a hierarchy or at least one-way relationship of some kind? And then, as you say, we happily talk about the mind affecting the body.
I reckon it's because the idea is to account for 'mental' things, which are supposed to be of a different kind from physical things. So it's the old mind-body or mind-matter 'problem' in a different guise.
But, as ever, it's only a problem - needing a solution - if we keep taking mentalist talk - about minds containing mental things and event - seriously, despite its obviously metaphorical nature. Using the rules of one language game inappropriately in another.
And I think the related argument between compatibilists and incompatibilists is also stuck - in that case with an old faculty psychology where the nature of 'the will' supposedly needs explanation.
