After 20 years of studying the relation between language and the mental representation of numbers, I’ve come to the conclusion that three things are true. (1) Numbers are unrelated to language; (2) Numbers are related to language in general; and (3) Numbers are related to particular languages. These sound like contradictory statements, but I will explain during my talk how all of them can be true, depending on what one means by ‘language’ and what one means by ‘number.’
