Hi Jesse,
I think the point is that arithmetical realism is a faith. That every number
has a successor is an axiom, thus considered as true. But while I believe in
arithmetical realism I can conceive that other people don't and see
arithmetical realism/plantonism has not true/real... that somehow a conscious
being is necessary for true statement to exists (I don't think that, and has
I wouldn't want to put words in Tom mouth, I wouldn't say he think that too)
