Because it involves slightly less typing than "physicalism" and most of the time it doesn't make any difference.
Then why did you say that the difference was important?
No, I meant we are in unknown territory in terms of this debate, because I have no idea how you delimit science.
What limits/defines science?
Science is delimited practically to what is at least indirectly observable or what can be verified by at least indirect observations.
"real" != "physical" unless you are a physicalist.
I am not sure how that is relevant. You refuse to give a definition of what you mean by physical - I don't know of a useful one. So what meaning can this statement have?
None.
But is there something real and non-abstract that science should not even try (for some reason) to study? Can you think of any?
Maybe science
can't study some things for practical reasons. But if it can it should.
What can physics do with randomness? Physics describes how X affects Y. When you have randomness you have a situation where Y is being affected but there is no X. You can describe the relationship between X and Y but you cannot describe the relationship between [void] and Y.
Do you really want me to go into the many useful things developed using QM?
In fact you can say quite a bit about the relationship between [void] and Y as long as you know about Y.
And what you can't say about it is useful too because the reasons are important. Science does not depend on determinism. If it did it would not be a useful tool for describing the world.
Yes, do you understand the implications?
Yes, the implication of the part I quoted is that many universes is a result of the maths and therefore empirical.
It may turn out to be wrong, but it is based on the maths.
The many universes conjecture pre-dates the Anthropic Principle by more than a decade. It is held by many who have no time for the Anthropic Principle.
Just because people are smart does not mean they are always right. Look at Kepler and his later work - which was downright woo.
