The origin of our agreement on true or false usually comes from these things. But they are still agreements. That's why we have to teach our children language. Most children come wired to mirror their parents behavior. When we point to something blue, and say it is blue, they accept it without challenge because they haven't developed the capacity for challenge. It becomes axiomatic.
