Just a caveat: Wildberger subscribes to a strict, non-mainstream view that rejects the existence of infinite objects. His exposition is fantastic, and as you say the content is definitely thought provoking if you have enough mathematical sophistication to (at least superficially) understand what he's about, but I wouldn't recommend it to anybody who hasn't taken a traditional real analysis course.

Yes, should have mentioned that. It’s not always clear, even though he rarely fails to mention it :)

Thanks for clarifying.
