Was mathematics invented or discovered?

What would it mean to say that mathematics was invented and how would this be different from saying mathematics was discovered? Is this even a serious philosophical question, or just a meaningless, tautological linguistic ambiguity? In the context…

Are numbers real?

I am confused as to what numbers are. Numbers are defined to be what they are, so numbers aren't real? But numbers are found in nature, right? So if we invented them, how can they be found in nature? How can everything be based on something that is…

If there were only one single mathematician in the world, would they be able to produce a mathematical proof?

If there were only one single mathematician in the world, would they be able to produce a mathematical proof? This question was motivated by the Math stackexchange question: Should a mathematical proof be 'convincing'? I thought it would be more…

Is there a notion of "because" in mathematics?

Sometimes, in math classes, we are asked to give justification for our mathematical assertions. We say that mathematical statement X is true because Y is true. However, I don't know if "because" is the right word to use. Mathematical objects and…

What is mathematical existence?

When I make a claim in a proof that a mathematical entity exists, is this no more than saying that the theory I'm working within is consistent, and that all the steps upto that point in the proof are allowed moves in the theory? By mathematical…

Can mathematics be separated from the physical world?

I am a math enthusiast, with very little interest in physics. In fact, today I thought to myself how can I expel the physical world from mathematics completely. However, this has proved to more difficult than I had previously thought. The notion of…

What is the philosophical status of category theory?

In the philosophy of mathematics, some attempts have been made to give it ultimately secure foundations; a notable example is the Hilbert Program. Goedel's Theorems show that it is not quite possible, but there are some partial results. Most such…

How is 0 defined?

I know that the naturals are assumed by the axiom of infinity, but the relationship between them (eg 1+0=1), must be rule based or defined at the very least. Basically I want to know what makes 0 or 1 abstract. For me to figure that out, I must also…
