In the film Arrival, the protagonist, Dr. Louise Banks, sets about trying to communicate with aliens. The methods she uses appear to succeed, but there is a very unusual effect of learning the alien language. This is rooted in the idea that a language is not just a system of communication but also implies a certain frame of reference.
Wittgenstein and the Philosophy of Meaning
The German philosopher Wittgenstein suggested in his early works that the meaning of words must be the objects or relations to which they refer in the world. The meaning of the word ‘table’ is literally the physical object to which the word refers—the table.
But after he left philosophy, Wittgenstein tried his hand at many professions: gardener, architect—he even taught small children. And when he did, he observed how children learn language and came to the conclusion that he had been wrong about what constituted meaning.
Wittgenstein came to recognize two things: one, that words are arbitrary signs with no natural connection between a word and what it means; and two, that meaning is defined by use.

Children Learning Language
Wittgenstein observed that the children he taught learned language not by figuring out which words belong with which objects, but by trial and error. Roughly put, a child uses words and phrases and checks to see if he has done so correctly by observing the reactions of others.
If the child uses them like others, he will get a positive reaction and the child will continue to use the word in his way; if he does not, he will get a negative reaction and try a different use next time. In this way, he will come to understand the meaning of words and phrases.
So, a word like ‘congratulations’ can have meaning, even though it does not refer to an object or relation in the world; and someone can learn its meaning by discovering how it’s used.
A child might think it has a certain meaning when he hears it used at a wedding and a graduation to those he saw on stage, but learn he had the wrong meaning in mind when he is scolded for saying “congratulations” at a funeral to someone who just gave the eulogy.
To learn a language is, essentially, to learn the use rules of a community’s language game.
In one of his later works Wittgenstein said, “The common behavior of mankind is the system of reference by means of which we interpret an unknown language.” About this passage, philosopher Hans-Johann Glock writes:
[According to Wittgenstein] [w]e can solve the problem of radical translation because we share with the natives certain basic forms of human behavior. This idea is linked to [Wittgenstein’s] claim that “the speaking of a language is part of a form of life”, i.e., a communal practice in which our language games are embedded.

Sharing a Form of Life
In other words, because people all share a form of life, no human language is completely foreign to other humans. Perhaps people even share a form of life because they all share a universal grammar.
But this would not be true of non-humans. “If a lion could talk”, Wittgenstein says, “we could not understand him.”
It is likely that humans wouldn’t share a form of life with aliens either. Neither would they share an innate universal grammar. Because the aliens evolved on a different planet, under completely different conditions, it would seem very unlikely that they would conceptualize the world and utilize language in the same way as humans. Would aliens even have vocal chords? A written language? The concept of a question? A conditional, if/then statement? Subject, verbs, and predicates?
Unless evolution somehow guarantees a similar conceptual framework or universal grammar is somehow truly universal and aliens share it—or, as Wittgenstein might put it, unless we share a form of life with aliens—real radical translation might actually be impossible.
Now, in Arrival, things work both ways. A shared conceptual framework makes the acquisition of the alien’s language possible, but learning the alien’s language causes Dr. Banks to share their conceptual framework. She begins to see time as they do, no longer experiencing one moment at a time, but seeing it all, past, present and future ‘as a whole’, ‘all at once’, and ‘from above’. She adopts a four-dimensional point of view.
Before she marries Ian Donnelly, she sees the future of them having a child, the child dying of a terminal illness, and it tearing their marriage part—and yet she does it anyway.

Learning a Conceptual Framework
The linguistic theory directly referenced in the film is the Sapir-Whorf hypothesis, also known as Whorfianism—which, unlike Lt. Worf’s forehead, comes in both a rigid and non-rigid form.
The stronger rigid form is expressed in Arrival. “The language you speak determines how you think … It affects how you see everything.” In its weaker form, Whorfianism merely suggests that linguistic concepts influence someone’s decisions and thinking.
According to linguist Panos Athanasopoulos, Professor of Linguistics and English Language at Lancaster University, even people’s languages might affect how they view time.
For example, English speakers think of time in terms of length, whereas Swedish speakers think in terms of volume. This causes them, in experimental conditions, to say different things about how much time has elapsed, depending on whether they are watching something increase in length or volume.
So, the basic idea of the film Arrival is this: How someone sees the world is influenced by the conceptual framework of the language they speak. This is why Dr. Banks learning the alien language enables her to see the universe four-dimensionally.
