The existentialist tradition from which Greene drew understood freedom not as the absence of external constraint but as the exercise of a capacity — and the capacity requires imagination. The person who cannot imagine an alternative to her situation cannot act to change it. She can only repeat the given, and the repetition, however efficient, is captivity.
Imagination in Greene's usage is not fantasy or escapism. It is the most rigorous cognitive act available: the capacity to perceive what is not yet, to see through the surface of the given world to possibilities it conceals, to refuse the comfortable finality of this is how things are. Without this capacity there is no agency — only execution.
The AI tools release imagination by closing the gap between vision and execution for builders whose imagination had always exceeded their technical capacity. The designer who could see interactive prototypes but could not code them can now build. The teacher who could envision educational tools but could not create them can now create. The release is genuine, morally significant, and irreversible — a liberation in the existential sense that the expansion of the field of possibility within which a person can act.
But imagination without judgment is not freedom. It is impulse. The machine will build whatever it is told to build. It does not ask whether the thing deserves to exist, whether the people who will live alongside the artifact have been considered, whether the vision has been tested against ethical scrutiny. These are human responsibilities — the responsibilities that freedom imposes on every person whose imagination has been released.
Greene drew the analysis most directly from Sartre's Being and Nothingness (1943) and What Is Literature? (1948), supplemented by Beauvoir's Ethics of Ambiguity and Freire's Pedagogy of the Oppressed. She articulated the synthesis most powerfully in The Dialectic of Freedom (1988).
Freedom requires imagination. The capacity to conceive of an alternative is prior to the capacity to act toward one.
Deeper imprisonment. When the imaginative horizon contracts to match the given, no external removal of constraint produces freedom.
Not fantasy. Imagination in Greene's sense is rigorous perception of unrealized possibility, not escapist daydreaming.
AI as release. The tools close the vision-to-execution gap for millions, enabling imagination that had been structurally blocked.
Judgment required. Imagination without the judgment to evaluate what should exist produces impulse, not freedom.
