A funny insight about Platonism (if it's not funny, treat this as a bad joke) I think aka "∅" therefore I know I thought aka "{∅}" therefore I know I knew I have thought aka "{{∅}}" and ... boom! The entire Math system is imported. (BTW, limitations known as "computation theory" is also introduced) So maybe we are actually mathematical being on a manifold named as "real world". To me it is more concise and profound than "philosophy". As we are real, so do all mathematical objects.
