"The Arrival" (2016)

Linguistic Relativity holds that a language affects the speaker’s worldview or cognition in nontrivial ways. The hypothesis is naive when applied to common languages. There is just not enough variation between the vernacular languages to inculcate individuals to substantially different ways of thinking.

Mathematics and economics are the languages that are sufficiently different from the vernacular, however, to shape reasoning in a distinctive manner. Mathematics makes one act as if arguments are won by persuasion, not by charisma. Economics puts one into the habit of identifying positive-sum games and turns one into a consequentialist.

The best gift of language one can receive are the languages of economics and, by implication, mathematics (which is the hardware on which economics runs). In 1940, Hardy praised pure maths for being useless and, therefore, harmless. We have moved some way forward since then. We have a language that is better than harmless: it is useful in opening up the opportunities to cooperate and in enabling one to think through cooperative strategies.
