    Part of a larger discussion

    Challenges→The semantics of second-order logic depend on the metatheory with respect to the Axiom of Choice.

    Kreisel's squeezing argument supports the view that our pre-theoretic notion of logical validity is determinate even when formal metatheories disagree, so Cohen-style independence results do not destabilize the semantics of second-order logic.

    Key Terms

    Destabilize(as describing what independence results might do to our understanding of logic)
    To undermine or call into question the reliability or fixed nature of something.
    Formal metatheories(as competing frameworks for understanding logic)
    Mathematical systems that study other logical systems themselves—basically, formal rules about how logic works.
    Independence results (Cohen-style)(as potentially problematic for the stability of logical meaning)
    Mathematical discoveries (pioneered by Paul Cohen) showing that certain statements cannot be proven true or false within a given logical system.
    Kreisel's squeezing argument(as a defense of our basic understanding of logical validity)
    A logical argument by philosopher Georg Kreisel that tries to show our intuitive understanding of something (like what makes reasoning valid) is actually precise and definite, even if we can't fully prove it yet.

    Start fresh with something unrelated.
    Pre-theoretic notion(as applied to how we naturally think about valid reasoning)
    An intuitive understanding or idea we have about something before we try to formalize it into a scientific or philosophical theory.
    Semantics of second-order logic(as the thing that might be threatened by logical independence results)
    The system of meaning and interpretation for a more powerful type of logic that can talk about properties and relations, not just individual objects.
    determinate(Contrasted with determinables; taken to be independently posited in the causal/ontological economy)
    A maximally specific instance of a determinable property (e.g., scarlet as a determinate of red)
