>Another point about language. It’s dangerous to uncritically use terms like “divide” when talking about mental conceptions. That’s a term borrowed from the physical world, where objects can be divided into their constituent parts – like a big ball of clay being split into two small balls of clay.
>Numbers do not work like this. They are not composite objects. “4” is not actually composed of “two 2’s”, or “four 1’s”. “4” is a symbol for a discreet concept that we can actively manipulate in our minds.
>While we can practically “divide 4 by 2”, metaphysically speaking, that “division” didn’t happen until you performed the action, and it’s not the same kind of division that we’re used to in the physical world. It’s an active mental process. Numbers do not come “pre-divided” in the real world.
