Some defence of substance dualism

But is this by necessity something that must be connected to the QM level?

I supposed, to some degree, almost all proponent positions would be strengthened by the necessary (but insufficient) correlate-of-consciousness in the brain to be at the level of quantum biology.

However I think this idea of a very lawful, mechanistic physical universe and a spiritual being that is free from said laws feels like an odd combination. It seems better for both Psi and Survival if this universe and the spiritual universe are not so distinct in nature.

Heck, even this suggestion that something at the quantum level - the foundational level of matter AFAIK - is influenced by the activity of the soul is suggesting there is a causal continuity between matter & mind. Is the idea here that every spirit has some minimal PK ability, but can only shift particles at the QM level?

Actually according to the article I’m referencing in this thread:

If mind is not a part of the physical universe but is able to influence brain events, then violations of physical laws should occur at points of such mental influence. Using current knowledge of how the nervous system functions, the minimal necessary magnitude of such violations is examined.…
A variety of influences that could produce action potentials is considered, including the direct opening of sodium channels in membranes, the triggering of release of neurotransmitter at synapses, the opening of postsynaptic, ligand-gated channels, and the control of neuromodulation. It is shown that the magnitude of the disturbance required is significantly greater than allowed for under quantum-mechanical uncertainty.

I haven’t followed this argument to its end since I'm out of my depth when it comes to biology, but it suggests that the influence of the nonphysical mind must be well above the QM level.

Anyway, I think you touch upon the reasons why substance dualism fell out of favor (in academia) centuries ago.

Still, for most people, substance dualism feels obviously true. In my view, it is also the philosophy of mind that offers the best hope for survival.

Sadly, our intuitions about the world are not always true. Whatever reality is, it is immensely complex. A great example is time, which is not how we intuitively perceive it.

Therefore, I don’t assign much value to the argument that substance dualism feels true.
