I fully agree that there’s something special about mind-body correlations. There's definitely something 'deeper’ going on than mere coincidence. There must be a
causal relationship behind mind-body correlations. But what is the nature of this causal relationship?
One thing that must be pointed out right from the outset is that causation must be ‘noumenal’, or imperceptible. And by restricting causation to that area of existence which is ‘noumenal’, we definitively rule out the possibility that human sense-organs are the cause of mind-body correlations since your own human sense-organs belong to that area of existence which is ‘phenomenal’, or perceptible. Something else, then, besides human sense-organs must be the cause of your mind-body correlations, but what? I think we can make several reasonable inferences about the attributes of this causal entity.
The causal entity must have the following attributes:
- Powerful (this causal entity must be of extraordinary power since it is creating and sustaining the entire perceivable world, which includes your mind-body correlations)
- Intelligent (this causal entity must be of extraordinary intelligence since it is creating and sustaining incredibly intricate and orderly perceivable relationships, including your mind-body correlations)
- Immutable (this causal entity must be unchanging since perceptions are constantly changing)
- Omnipresent (this causal entity must be omnipresent since it is causally present anywhere a perception exists and, on idealism, perceptions constitute the entire world)
- Spaceless (this causal entity must be non-spatial since space is an aspect of perception)
- Eternal (this causal entity must be eternal since it must exist outside the temporal succession of perceptions. It must also be eternal since it exists uncaused)
... I could carry on arguing for more attributes (like ontological simplicity) but I think you get the idea. We end up with a God-like entity who is the cause of experience (including the experiences that constitute mind-body correlations). Thus I conclude that the
God of classical theism is cause of your mind-body correlations, not human sense-organs.
There’s really only two options here: You either have to claim your perceptions exist uncaused (which you yourself admit do not find plausible) or posit some God-like entity that causes perceptions.
