What is the difference between methodological materialism and metaphysical ? Basically is it a difference of principle/practice

What do you mean by "even if it has broken down upon close analysis"

I see , but what exactly did you mean in response to my second question "biological limits in physical context"

Well the only reason it's disturbing for me is that , that way we can't know that treating or curing certain diseases are possible and/or have a model for engineering attempts at our biology

yes I edited it to another question

In the response to the third question , you said "yes" , which line were you replying to ?

Edited

What exactly would the purpose of immutable laws be in those fields though , wouldn't they just be describing physics limits in those fields

I.e supply and demand in economics is a representative of the scarcity in our universe

I mean in scientific terms

There was a comment regarding logic a while ago
That got my attention

> Be careful with the logic they study in the typical philosophy course.

> They only handle the very primitive beginnings of it. They do not even seem to deal with 19th century Boolean algebra, let alone with serious mathematical logic.

> Using that primitive tool, i.e. just some bits and bobs of Aristotelian logic, you won't get anywhere.

> Without a firm grasp on the work of Gödel, Tarski, Church, and Turing, you won't be aware of the fundamental limitations of first-order logic, especially, when dragging basic number theory (PA) into the fray.

> You will easily overestimate what is possible, simply, because you do not know that it is completely impossible. That is one of the many reasons why the absurd optimism of contemporary philosophy quickly degenerates into mere bullshit.

Wouldn't this comment imply that even logic develops ? And isn't enough to know possibilities

Isn't the problem of induction something in philosophy as well ?

Doesn't physical possibility depend on weather or not physics governs everything ? And can fields like biology and chemistry have their own immutable laws i.e survival of the fittest ?

Is physics the only field which has a "theoretical aspect" ?

May I ask How so ?
