The statement you provided seems to be discussing the concept of modal logic in the context of a divine being, often referred to as "God" ("上帝" in Chinese). Let's break down the statement and elaborate on its meaning:

1. Modal Logic: Modal logic is a branch of logic that deals with the use of modalities, which are words or phrases that express modality. Modality refers to the way in which we understand possibility, necessity, contingency, etc. Modal logic provides a framework for reasoning about these modal concepts.
2. "上帝说" ("God says"): In this context, "上帝" refers to a divine being, often conceptualized as God. The phrase "上帝说" implies statements or propositions attributed to God.
3. "能证或不能证推出的是 '上帝说' 的非必然性": This part of the statement suggests that whether something can be proven or not proven implies the contingency or non-necessity of what is attributed to God. In other words, the truth or falsity of a proposition attributed to God is contingent upon whether it can be proven or not.
4. "而不是证的非必然性": This clarifies that the non-necessity being discussed is not about the proof itself, but rather about what is attributed to God. In other words, it's not about the necessity or contingency of the proof process, but rather about the nature of the statement attributed to God.

In summary, the statement is discussing how modal logic applies to propositions attributed to a divine being. It suggests that whether something can be proven or not proven affects the contingency or non-necessity of what is attributed to God, rather than the process of proof itself.
