Light and darkness

Light and darkness in the novel are at once physical conditions and measures of whether life, knowledge, and continuity can endure. As the unattended electrical system fails, Ish watches familiar lights dwindle into darkness and experiences the loss as the death of an old world; later, Em’s courage and the child she carries turn light toward a future no power grid can guarantee.

The failing electrical light

The motif first becomes intimate in Ish’s living room. Shadows seem to move out from behind the chairs, and he thinks, "The lights are going out. The lights of the world!" The phrase enlarges a change in illumination into a verdict on civilization. Princess, dozing on the floor, cannot understand what the lights mean, but she senses Ish’s nervousness and approaches him, sniffing and whining. His fear is therefore legible even to a companion for whom the electrical crisis itself has no meaning.

Outside, the streetlights grow weaker and yellower minute by minute. Ish imagines the wind damaging power lines and the spreading forest fire burning lines or powerhouses. When the glow stops fading, he brings a second bridge-lamp beside his chair and manages to read by two lamps instead of one. The small adjustment offers temporary practical relief, not reassurance: it is late, but he does not want to sleep. He feels as if he is keeping vigil beside the deathbed of his oldest and most treasured friend. Recalling "Let there be light, and there was light!", he sees the failing system as the opposite end of that creation story.

The narrative later supplies the material weakness behind the apparent mystery. The generators could keep spinning, but their governors required people to inspect them for oil every ten days and replenish it perhaps monthly; no one had made the controls wholly automatic. After two months without care, oil ran low. As governors failed one by one, water passed through the nozzles without turning the wheels, taking generators out of service and placing ever greater strain on those still operating. Light’s symbolic collapse is thus tied to a specific maintenance routine: the system does not fail because its energy source vanishes at once, but because a chain of dependent parts cannot sustain itself without human attention.

Darkness and the end of the system

When Ish wakes, the lamps have faded to orange-red filaments, dim enough to look at directly, and the room is half-dark although he has not switched any lamps off. The repeated words "The lights are going out! The lights are going out!" carry, for him, centuries of human fear and metaphor. Light has stood for the world, life, and knowledge; its physical disappearance makes those meanings newly vulnerable. He shivers, then steadies himself by remembering how long the Power-and-Light system continued to function after people were gone. On the first day he came down from the mountains, still unaware of what had happened, passing the powerhouse had reassured him that things were normal. The same infrastructure that once comforted him now reveals how long an absent society can persist in its remnants—and how finite that persistence is.

The ending is delayed rather than instantaneous. The filaments fade to cherry-red; Ish stays awake, wishing the end would come quickly instead of being prolonged, and thinks, "This is the end!" The lights then seem to gather momentum in their descent, like a sled moving down a hillside. For an instant they may flare brighter, or Ish may only imagine that they do, before going out. Princess stirs and gives the half-bark of a dream. The domestic quiet does not soften the loss: outside, smoke thickens the darkness and turns the moon orange, and Ish can see no lights in the streets or anywhere on the bridge. He concludes, "Let there be no light, and there was no light!" Yet the scene does not end in pure biblical grandeur. He tells himself there is no use being melodramatic, finds the candles kept in his mother’s drawer, and sits by their weak but steady flame, still shaken. The candle cannot restore the city, but it makes visible the difference between a system’s exhausted glow and a small, continuing source of light.

Light as inheritance and hope

Light’s meaning is not exhausted by the electrical failure. Ish’s fear of darkness belongs to a larger fear that human knowledge and collective life may end with his generation. The lights had seemed to connect the present to a world whose systems still worked without their makers; their extinction makes that inheritance visibly finite. The motif therefore joins the novel’s technical account of unattended infrastructure to Ish’s emotional experience of being left behind. Its force comes from keeping those scales together: an orange filament is both a lamp approaching darkness and the last, fragile operation of a human-made order.

After Em becomes pregnant, the image changes direction. Ish still carries a fear that she might die in childbirth and that hope for the future might disappear with her, but he cannot sustain that fear in the face of her courage. He understands her as life and as "the light for the future," with the children who may come from her extending that light beyond the two of them. Unlike the electric lamps, this brightness does not depend on governors, oil, or an intact grid. It is bound to a person’s strength and to the possibility of new lives. Ish, who once imagined death creeping closer as darkness had crept from the corners of his room, now feels courage flowing from Em to him.

The expected child changes Ish’s sense of time as well as his sense of hope. He looks forward to the sun reaching the southern end of its long arc again and to himself and Em—or the three of them—carving the mark for the end of Year One into rock. The image places renewal in a modest act of recording, not in the return of electric civilization. His confidence rests on the thought that the story is unfinished and will go on. In this movement from failing lamps to the sun, from a solitary vigil to a future family, light and darkness give the novel a way to distinguish the end of one civilization’s machinery from the possible continuation of human life and memory.
