01 · Who wrote what
Every character, traced to its author.
Attribution is counted per character, never guessed. See each person’s share of the document, what they wrote, what they deleted, and how fast they typed.
The Distance of the Green Light
Gatsby reaches toward the light across the bay as if it could close the space between the past and the present. Fitzgerald returns to it three times, and each time it is farther away.
By the final chapter the light has lost its color entirely; what remains is the reaching, the boats against the current, and a reader who knows how the story ends before Gatsby does.
The novel’s quiet argument is that longing outlives its object.
