The Bronx is the New York City borough that serves as the birthplace and formative ground of the novel's narrator, Everett. It is the place where his personal history begins, and it anchors the book's larger philosophical inquiry into how individual identity emerges from, and remains entangled with, the teeming collective life of the city. The borough is not merely a geographical setting but the origin of the narrator's way of seeing the world — the vantage point from which he later contemplates the masses of Manhattan, the birds of Valdemingomez, and the ants of Central Park as instances of a single, mysterious pattern of aggregate thought.

Birth and Early Life

The narrator's life begins in a lying-in hospital "no bigger than a brownstone" on the corner of Mt. Eden Avenue and Morris Avenue in the Bronx, in the year 19–. He was a breech baby, the first of many difficulties he gave his mother, Ruth, a resolute woman and a gifted pianist. This origin is marked by a kind of physical and narrative awkwardness — the breech birth foreshadows a life of arriving sideways into situations, and the modest scale of the hospital, no grander than a brownstone, establishes the unpretentious, working-class texture of the borough as the narrator's native ground. The Bronx of his birth is a place of small buildings and determined mothers, a world away from the monumental architecture and intellectual ferment he will later encounter elsewhere in the city.

The Bronx High School of Science

The most consequential institution of the narrator's Bronx years is the Bronx High School of Science, the specialized public school that shaped his intellectual formation. He describes the "brilliant boys" he knew there whose minds were made to solve mathematical problems and skip happily among the most abstruse concepts of physics — and notes, with characteristic wryness, that a large number of them were jerks, a judgment he has since confirmed by encountering them in adulthood, still jerks. The school is also the site of a specific, telling memory: a fellow student who would plop down next to him in study hall to copy his algebra homework. This student, it emerges, was Murray Seligman, a figure who never tied his shoelaces and whose teeth were green. The detail is comic, but it carries a deeper resonance: the Bronx High School of Science is where the narrator's own intellectual path was set, and where he first encountered the odd, unpolished brilliance that the novel associates with the borough's particular strain of Jewish-American life.

The Borough and the City's Collective Life

The Bronx functions in the novel as the counterpoint to the narrator's later meditations on the city as a whole. Standing on a corner at the intersection of two busy streets, he reflects that before him are thousands of lives headed in all four directions — uptown, downtown, east and west — on foot, on bikes, on in-line skates, in buses, strollers, cars, and trucks, with the subway rumble underneath his feet. He calls this "the most spectacular phenomenon in the unnatural world," a "primatial over-soul" in which each passerby, every scruffy, oversize, undersize, weird, fat, bony, limping, muttering, or foreign-looking person, is a New Yorker, "as native to this diaspora as I am." The Bronx, as his birthplace, is the ground of this universalist vision: it is where he learned to see the city as "a great sputtering experiment in a universalist society proposing a world without nations where anyone can be anything and the ID is planetary." The borough's own history — a place of immigrants and strivers, of small brownstones and determined mothers — is the seed from which this planetary imagination grows.

The Bronx and the Ecological Imagination

The narrator's Bronx-rooted perspective extends to his observations of the natural world within the city. In Central Park, he hunkers down with the boys to watch a brown ant population building an underground city, each ant not an eighth of an inch long, and he explains to the kids that these are "domesticated Central Park ants, the house sparrows of the ant species" — the simplest, most modest kind, unlike the big ones in the jungles and rain forests that build leaf bridges, cultivate crops, float across rivers on rafts, march, make war, and eat meat. This ecological vision, which sees the city as a habitat continuous with the wider natural world, is an extension of the narrator's Bronx-formed sensibility: the borough taught him to look closely at the small, the overlooked, and the collective. The ants' "invisible organ of aggregate thought," an unlocatable group brain beyond the capacity of any single ant to understand, becomes his model for understanding the city itself — and the Bronx, as his point of origin, is where he first learned to see the whole from the part.

Narrative Significance

The Bronx is thus not a setting in the conventional sense but the novel's origin myth — the place where the narrator's consciousness was formed, where his intellectual path was set at the Bronx High School of Science, and where he first encountered the paradox of the individual and the mass that structures his entire worldview. The borough's modest scale, its brownstone hospital and its specialized public school, its brilliant jerks and its green-toothed future rabbis, all feed into the novel's larger argument about the city as a living organism, a collective brain in which each person is a single cell. The Bronx is where the narrator learned to be a New Yorker, which is to say, as he puts it, "as native to this diaspora as I am" — and from that native ground, he extends his vision outward to the birds of Valdemingomez, the ants of Central Park, and the millions of lives crossing at the intersection of two busy streets.
