    Supports→Vagueness does not exist in the world itself.

    Key Terms

    Equally legitimate(as used in epistemology)
    Having the same level of validity or justification; one is not better supported than the other.
    Lewis(philosopher who created the similarity metric being discussed)
    David Lewis was a famous American philosopher who developed influential theories about possible worlds—alternative ways reality could have been.
    Sharp extensions(as the possible precise meanings of vague words)
    The precise, boundary-free meanings you get when you fully specify a vague word. If you decide exactly where 'tall' begins and ends, that's a sharp extension of the vague word 'tall.'
    Worldly properties(as what the bridge principle should map onto)
    Actual characteristics or qualities that exist in the real world outside our minds, like the redness of an apple or the hardness of a stone.

    A predicate P that exhibits borderline cases for which it is not clear whether P truly applies or not
