(Actually you CAN'T prove that arithmetic is consistent using arithmetic itself, that's Gödel's second incompleteness theorem, but we don't need to get into that) Whether 2+2=4 in real life is entirely dependent on how you count and measure the four things, whatever they are

Of course that process is subjective, it's carried out by a subject Your friend even brought up the example of a crooked street vendor, which is the *perfect example* of how using the same "rules of math" gets you different results if you measure a different way

Interesting thread. I am ignoring Lindsay because he is an opportunist trying to win a fake culture war. Your patience is endless — the willful, smug obtuseness about nothing. Our idea of absolutes in math is still imprecise. Not controversial.

You can demonstrate that *given* a particular application, there can be correct and incorrect answers. The application assumed by anyone not trying to play games when considering 2+2=4 is that of counting individual items taken as units. Like, i don't know, maybe your fingers.
