The dialectic of fatalism and free will

The Dialectic of Fatalistic Destiny and Active Choice

The deepest question Arrival poses is the philosophical paradox: 'If you know the future, does free will disappear?' This question is, beyond an SF device, an inquiry into the fundamental will (Will) of human existence. Through the process of Louise Banks understanding the non-linear flow of time via communication with alien civilisation, the film casts doubt on the very premise that the human concept of time is 'linear.'

1. The Paradoxical Power of Knowing the Future: Motivation, Not Despair

The general fatalistic view interprets that if everything is already determined, every human action is merely 'performance' following a predetermined script. If Louise were to learn the future of her daughter's death, she might either fight desperately to prevent that tragedy, or abandon all effort and sink into helpless despair.

Yet the film shows that Louise does not become helpless despite having this ability. On the contrary, she clearly perceives the pain of the future (her daughter's death) and yet 'chooses' to experience those moments fully. This choice is not mere emotional avoidance. It is an active, deliberate decision to acknowledge the colossal background fact (Fact) of destiny while still pursuing within it the most human and valuable things (love, connection).

This interpretation argues the paradox that knowing the future is not despair, but rather a powerful motivation to cherish the present moment even more. In other words, knowledge of the future tells us 'what will happen' but does not deprive us of the right to choose 'how to live.'

2. The Difference Between Film's 'Choice' and the Novel's 'Destiny'

The depth of this theme becomes clearer through comparison with the source novel. The perception of the future in the novel is close to 'destiny.' One knows the future but cannot and must not change it, so the characters tend to calmly accept the given future. This leads to the fatalistic conclusion that free will can hardly exist.

The film, by contrast, makes an important adaptation at this point. The decisive move is changing the cause of Louise's daughter's death from 'a fall during rock climbing — an accident easily preventable by free will' to 'a terminal illness that modern medicine cannot cure.' This change of setting presupposes that Louise knows the future yet has no room to prevent the tragedy. Therefore, her act of choosing to spend time with her daughter is interpreted not as resisting fate, but as the active will itself of choosing the most human value within destiny.

3. Free Will from a Linguistic Perspective

This philosophical discussion is ultimately completed through the medium of 'language.' Louise's process of learning an alien language is an experience that, beyond mere translation, reconstructs the very mode of human thought. As Ian's narration goes, the hypothesis (a variant of the Sapir-Whorf hypothesis) that 'a person's thought is shaped by the language they use' is applied, and Louise escapes the linear temporal concept of the human mode of thought, assimilating to a non-linear mode of thought in which past-present-future coexist simultaneously.

This linguistic change enables her to transcend the limitation of perceiving the flow of time 'linearly,' and consequently enriches the concept of 'choice.' She is no longer a being swept along by the flow of time, but a subject who understands the multidimensionality of time and is thereby able to exercise her own will.
