    Challenges→Hume's Principle does not require that the domain of numbers be as large as the domain of concepts

    Hume's Principle, via Frege's Theorem, actually derives the full Dedekind-infinite sequence of natural numbers, making the number domain as large as any infinite concept-extension.

    Key Terms

    Concept-extension(in philosophy of logic)
    The collection of all things that actually fit a particular idea or category—for example, the concept-extension of 'red things' is everything that is red.
    David Hume(as referenced in the statement)
    An 18th-century Scottish philosopher who argued that our desires and emotions, not reason alone, drive our actions and decisions.
    Dedekind-infinite(one of several definitions of infinity being compared)
    A way of defining something as infinite based on the idea that it can be matched up with a proper part of itself (like how the whole numbers can be matched with just the even numbers).
    Frege's Theorem(in logic and mathematics)
    A mathematical proof showing that you can build all the natural numbers (0, 1, 2, 3...) starting from basic logical rules and Hume's Principle.
