People, animals, plants... all life, all that is in the universe must necessarily be an expression of first principles.
So are proteins just a gestalt of first principles? Why to they spell "words" in DNA? There is an abstract principle of order working here IMO, (part of first principles). Hmm. Pardon, just meandering on topic.
I should say though that I agree that "souls" is basically a term expressing ignorance. In argument of Boris's point though and as I've said, it seems to me that there IS a "non-material" (in the classical sense) aspect of mind (perhaps just "organization" (which itself is a concept with no physicality)) that doesn't exist "separate" from it, but as part of it.
Yeah okay I'm still meandering. Sorry.
