Now I feel silly for only reading this after posting my own part two that repeated many of these points :)
As I said in my reply to CronoDAS’s comment, I think I make a slightly different distinction: mental objects in your big collection’o’mental’objects are what you can think sentences about (and evaluate the truth of, and have arguments about, etc), but you aren’t required to think all of those things exist. I argue that it feels like numbers exist because when we learn about numbers, it feels like we’re interacting with something objective and external.
