Week 9: Language and thought

The film makes a strong claim about language and thought. The evidence supports a much weaker version of it, which is the more useful claim to examine

19 April 2027

Arrival is adapted from Ted Chiang’s “Story of Your Life”, and it makes its central claim explicitly: learning Heptapod B restructures Louise’s cognition until she perceives time non-linearly. Language determines thought, totally and irreversibly. This is linguistic determinism, the strong form of what usually gets called the Sapir–Whorf hypothesis, and it has almost no support in the field.

It is worth being precise about what Whorf actually wrote, because the position attached to his name comes largely from his critics and popularisers. It is also worth being precise about what the strong claim would require: if your language genuinely determined what you could think, translation would be impossible and learning a second language could not change anything, since you would have no way to think the new thoughts in order to acquire them.

The weak version is a different claim, and it holds up under experiment. Speakers of languages that divide the blue-green region differently discriminate those colours measurably faster at their own category boundary. Guugu Yimithirr speakers, whose language uses absolute compass directions rather than left and right, maintain an accurate sense of orientation that speakers of languages like English generally do not. Grammatical gender nudges the adjectives people reach for. These are real, replicated, and modest — language influences attention and habitual categorisation rather than determining the limits of thought.

Your essay asks you to state the film’s claim accurately, then set out where the evidence departs from it.

Outline#

• the claim the film makes, where it makes it, stated fairly
• Whorf, what he wrote, and what was later attributed to him
• the effects that replicate — colour boundaries, spatial frames, gender
• how to argue with a film’s claim without treating the film as a research paper
