"And , a circle could be called a circle in the English language , but I could make up a new language in which a circle would be called a square and a square a circle ."
"But your new language would be meaningless . The definition of a circle or a square does not vary from language to language . Mathematical definitions are not matters of opinion but quite precise descriptions so that all mathematicians will understand what is meant when the term is used . The words may change but the meaning does n't . Math is not opinion . It is not my opinion that a triangle has three angles . That is a matter of definition . Apparently Habbit does n't understand that substituting the words of another language does not change the concept . That sort of argument is basically ignorant XXXX ."
