Dickinson treats hope like a paradoxical resource—it consumes without depleting. The poem opens with "subtle glutton," immediately breaking our expectations. Gluttons are obvious, excessive, visible in their consumption. But hope gorges invisibly, "feeds upon the fair" without anyone noticing the meal.
The central trick is in lines 7-8: "whatsoever is consumed / The same amounts remain." This is impossible economics. Normal resources—food, money, energy—diminish when used. Hope operates by different math. You can spend it endlessly and still have the same amount. This connects to Dickinson's more famous hope poem ("Hope is the thing with feathers")—both present hope as something that defies normal scarcity.
The "halcyon table / That never seats but one" deepens the paradox. Halcyon refers to the kingfisher bird and Greek myths of perfect calm seas, but here it's a table of abundance for a solitary diner. Hope isn't shared—each person has their own infinite supply. The loneliness of "never seats but one" cuts against the comfort of endless replenishment. You have infinite hope, but you're eating alone.
