The Metaphysics of Materialism
I agree with some of this, others not. There is very good evidence to suggest that [1] is not true: the universe cannot be understood by human beings, at least not metaphysically (which is the purpose of this thread) - the ultimate grounds of reality are sealed out for us.
[2] Is more terminological than anything else. Yes, there is a universe out there - it can be called "physical", "neutral", "material", "immaterial", it does not have consequences for our inquires- for whatever the universe is made of, whatever word is used - this is what we study.
[3] Yes, sure. We could substitute "laws" for "habits", but it is fine.
[4] Yes. Or at least, we can best describe its behavior through applied mathematics.
[5] Given the time period, perhaps this was assumed to be true. There may be exceptions, but, fine.
[6] Yes.
[7] So far as was known, correct.
[8] And assumed to be infinite too.
[9] Space and time are considered absolute and not the same thing, as is now the case.
Pretty good OP Clark.
