    Challenges→The meaning of a formula (the proposition expressed) does not represent a reality distinct from the linguistic system in which the formula occurs

    If the proposition expressed by a formula were constituted entirely by its role within a formal system, no proposition could be true yet unprovable within that system—contradicting Gödel's result.

    Key Terms

    Constituted(as describing how intersubjectivity is formed)
    In philosophy, this means 'made up of' or 'formed through'—describing how something comes into existence or takes shape through a process.
    Formal system(as used in logic and mathematics)
    A set of rules and symbols (like mathematical axioms) that you use to prove whether statements are true or false, similar to how a chess game has specific rules that determine what moves are legal.
    Gödel's result(as used in logic and mathematical philosophy)
    A groundbreaking discovery by logician Kurt Gödel proving that in any formal system powerful enough to do basic arithmetic, there are true statements that cannot be proven using that system's own rules.
    Kurt Gödel(the mathematician who disproved Hilbert)
    An Austrian-American logician (1906-1978) who proved shocking theorems showing that any complex formal system has true statements that cannot be proven using the system's own rules.

    proposition(Used in the context of a semantic theory sensitive to differences in subject matter.)
    The content expressed by a sentence, individuated at least in part by the subject matter of the sentence and the contents of its subsentential expressions.
    provable within a system(as used in logic and mathematics)
    Something that can be proven true using only the rules and axioms (starting assumptions) of a particular formal system—like proving a theorem in geometry using geometry's basic rules.
