THis topic seems to reflect the philosophical discussion we know for ages, e.g. Descartes and his 'duality' (here's the material world - here's the spirit world and only few connections) vs. the ideas of idealism or monism.
Very much so. I tend to think one of the monisms is likely to be true. Either everything is immaterial, and materiality is an illusion, or everything is material. It is hard to grasp why there would be two cartesian substances.
I do not think that what we call non-physical does have to have the same rules or any rules we know.
I would tend to agree. I think the laws of this physical are determined from above, and the next existence it is nested inside is not at all bound to those laws (but probably its own set).
Our minds cannot grasp the higher reality rulesets as long as we are here because according to this ruleset here we are not meant to have this capability.
I agree, their rules could probably not be learned from this vantage point. But I am pressing a different question here- can we reason the fact that they must have rules at all? I am supposing we might do this, with my instability argument above.
