Mathematics has a purely metaphorical connection to reality anyway. There’s not really two apples there when you start going deeper and deeper into it, for example. It’s a convenience that’s practical. Mathematics is convenient for humans to use. It’s a language we use and understand that works with our brains which have a need to form patterns rather than seeing everything as unique.
Our brains are tiny. We need to use patterns and form stereotypical views of stuff to form categories for compression and such. That’s my view anyway smile emoticon
