Reflection: Your Mathematical Reality
Philosophy of mathematics is not only for specialists, your implicit view of numbers reveals something about your metaphysics.
Prompts to consider
- Before this path, did you think of mathematical objects as real, as inventions, or as something else? Has anything shifted? If you're now less certain than you were, what produced the uncertainty, and is that a bad thing?
- Wigner's puzzle: mathematics developed for purely abstract reasons keeps turning out to describe physical reality. Think of a moment where you encountered mathematical structure in a non-mathematical context, in music, in nature, in architecture, in code. Did it feel like a discovery about reality, or like a useful tool you were applying? What does that intuition suggest?
- Benacerraf's dilemma shows that we cannot have both a satisfying semantics and a satisfying epistemology for mathematics simultaneously. This is a genuine, unresolved puzzle. Most of us just ignore it and keep doing mathematics. Is that intellectually acceptable? When is it okay to proceed confidently in a domain while leaving its foundations philosophically unresolved?
