Why would that make it effective, though? After all we also invented fairy
and conspiracy theories, and religion, and...)
And those fairy tales were effective too - up to a point. "Don't sleep near
swamp because the night demons will make you sick.", probably saved a lot
Fairy tales and religion "work", in this sense (when they do - there's a lot of nonsense
invented by humans, too!) because they encode knowledge about the world. So why does
maths work? If it encodes knowledge about the world, where does that information come from?
It doesn't encode knowledge about the world. It encodes relations between sentence, i.e.
axioms=>theorems. With suitable interpretation we can use it to model the world (and
evolution hardwired this to some degree): One apple and one orange makes two fruit. Two
tennis players and two basketball players make four players - oops, one of the tennis
players is also a basketball player, so it's only three players. Interpretation is essential.
