Oh come now, it's not wrong. I shall quote the article.

This is obviously referring to the natural numbers. It says so both before and after the statement you're talking about. There is no natural number whose square is negative one.
- lisper 5y agoLet's not lose the plot here. I was critiquing a piece called "Math Foundations from Scratch". It's a little hard to tell whether it was intended to be pedagogical, targeted toward people who didn't already understand the foundations of math, or a sort of review or reference, targeted at those who did. But either way I think it fails, notwithstanding the fact that the specific flaw that I cited, a circular definition of the word "number", appeared in the context of a discussion of natural numbers. That's my opinion. I've explained at some length why I hold this opinion, but it's still just my opinion.
