    Part of a larger discussion

    Challenges→Although actual infinites can have an ideal existence, they cannot really exist.

    Georg Cantor and contemporary set theorists like Quine and Maddy have shown that denying the part-whole axiom for infinite sets yields a consistent, well-developed mathematics that maps onto physical theories.

    Key Terms

    Axiom(as something that may be necessary or redundant in a logical system)
    A basic assumption or rule that you accept as true without proof, which then serves as the foundation for building other conclusions.
    Georg Cantor(as the originator of set theory)
    A 19th-century mathematician who invented set theory (a way of organizing collections of objects mathematically) and revolutionized how we think about infinity.
    Maddy(whose objections are challenging the indispensability argument)
    Penelope Maddy is a contemporary philosopher of mathematics who challenges Quine and Putnam by pointing out that scientists don't actually use mathematical objects the way the indispensability argument suggests.
    Maps onto(logic and mathematics in philosophy)
    Corresponds to or matches up with; when one thing 'maps onto' another, there's a systematic relationship between them.

    Start fresh with something unrelated.
    Part-whole axiom(as a mathematical principle being questioned)
    A basic logical rule that says if something is part of a larger thing, then the larger thing should contain all its parts (sounds obvious, but it breaks down in strange ways with infinity).
    Physical theories(as what the mathematics is being applied to)
    Scientific explanations of how the natural world works, like Einstein's theory of relativity or quantum mechanics.
    Quine(as a proper name referring to the philosopher whose theory is being discussed)
    Willard Van Orman Quine was a 20th-century American philosopher who wrote about how we know things and how language works. In this statement, we're discussing one of his specific ideas about observation.
    Set theorists(as the experts working with Cantor's ideas)
    Mathematicians and philosophers who specialize in studying sets and the logical rules that govern them.
    Set theory(as used in mathematics)
    A branch of mathematics that studies collections of objects (called 'sets') and the rules for how they relate to each other.
    consistent(Contrasted with the model-theoretic notion of satisfiability)
    A proof-theoretic notion indicating that no contradiction is derivable from a set of sentences
