The thesis:
......rational constructs derived from the principles of universality and absolute necessity.....
.....natural laws...... — frank
......rational constructs that act as explanatory devices for occurrences of a specific kind in Nature.....
.....happening by natural laws...... — frank
......that in Nature
determinable by that rational construct.....
X is (...) happening by natural laws..... — frank
.....that as an occurrence of a specific kind in Nature
determined by that rational construct....
X is logically necessary if it's happening by natural laws. — frank
....X is an occurrence of a specific kind determined by the principles of universality and absolute necessity, therefore because X occurred, it is necessary that it occurred, iff such occurrence is determinable by law......
Given the above,
is not mistaken.

The antithesis:
That isn't true, (X is logically necessary if it is happening by natural law), because we can imagine the counterfactual: our universe with different laws. — frank
.....therefore
is mistaken.

The theorem:
Even if we imagine different laws, they are still laws, by definition. Otherwise, something must be constructed that doesn’t adhere to universality and absolute necessity, in order to permit happenings that are not necessary merely because they happened, as natural law demands. In which case, it isn’t a law that is constructed, which leaves the truth of the original proposition is unaffected.
(Propositions regulated without universality and absolute necessity shall be deemed as rules, and depending on which predicates are assigned, deemed only convictions, and of ever lesser power, mere persuasions)
The proof:
Counterfactual indicates fact that negates established fact. You’re imagining our universe factually different. Regardless, facts are predicated on law, law is predicated on principles, but imagination is predicated on mere inclination. It is classically irrational to exchange the legislative power of principle, for the indiscriminate power of inclination, which are conditions of conviction or persuasion. It is therefore permissible to imagine anything to which one is inclined, but he has no business immediately addressing it as lawful. It follows that even if one images our universe as explainable by different laws, the universe in itself cannot be explained as being different in itself merely because our explanations relative to it, are.
In effect, there is no epistemologically legislative profit in imagining counterfactuals in opposition to established law, absent the exchange of imagination for law. Our universe as it is but explained by different laws is an empty conjecture until we actually have the different laws with which to explain it, to determine that it is possible to still understand our universe as well as or better than we do now, however different such understanding may be.
The conclusion:
That the universe may be explainable by different laws is not sufficient to falsify the truth of the proposition that X is logically necessary if it happens by natural law.

Epistemic possibility has nothing to do with that. — frank
How could it not? It is our human epistemology alone, which immediately makes any epistemic relation inescapable. We create the doctrine, we subject ourselves to it, therefore it is us. Nature, on the other hand, has nothing to do with our epistemic possibilities, but is only the occasion for its exercise.
