is infinity a number or a concept?

@beckychandler I´m not a nominalist, but...
A material "thing"?

@beckychandler Sorry, Becky if I´m wrong.
But seems, only seems, that your assertion comes from some kind of armchair philosophy and not from Math.
Nor from Science.

Scholastics anyone?

@CharlieZ William of Occam's idea plagues us today. Everything is just a name. If the government chooses to print paper (or digits) and call it money --well, it is money. If Sally decides to called herself a man, well by God she is a man. Nothing is real.

I am the realist.
