> If the brain is not the seat of consciousness and the self is instead the result of some metaphysical process that's external to the body,

This seems backwards to me. It is the self that is the result of processes from the interaction between consciousness and the body (including the brain).

Analogy: the sea does not create the matter of the stone it hits against on the shore, that is already present. But it is the interaction between the sea and the rock that shapes the rock, and in doing so it can create a pattern that looks like a face.

Processes are abstract concepts. They can't interact with concrete objects, except through the concrete objects that support them. Talking about consciousness interacting with the brain makes as much sense as talking about movement interacting with a car. It's a process that's running on the brain. If it can be said to "interact" with the brain, what's happening ultimately is the brain interacting with itself.

Okay, now undo the analogy.

Cars exist because the need for faster and better movement exists. The process of movement created the need for the invention of the car.

> Talking about consciousness interacting with the brain makes as much sense as talking about movement interacting with a car. It's a process that's running on the brain.

If we follow this logic then "movement is a process that's running on the car."

Cars are a result of multiple conditions, including movement and the necessary material conditions to employ movement in a specific way.

Consciousness is a result of multiple conditions, including mind and the necessary biological conditions to employ mental factors in a specific way.
