Adrian Duncan's A Thought Without Collision
A review of Adrian Duncan's fifth novel, A Thought Without Collision, which intertwines the lives of a gifted Irish girl and a Wittgenstein-inspired

Adrian Duncan's fifth novel, A Thought Without Collision, is reviewed in The Guardian. The book, set across 1923 Ireland and 1951 Scotland, follows a gifted child and a dying philosopher.
The Irish author's new work relates an experience of being mystified by the universe. It opens in 1923 Ireland, where six-year-old Catherine displays exceptional academic gifts while her father's farm fails. The narrative then shifts to 1951, introducing Dr Josef Alois, a Tyrolean émigré academic in his mid-50s living alone in a self-built Scottish house. Catherine reappears as a handsome Oxford professor in her mid-thirties. The chapter ends by stating Alois "is more unwell than he believes and will perish in one month and eleven days."
Philosophical foundations and form
Details of Alois's life and work are drawn from philosopher Ludwig Wittgenstein. The novel references his near-contemporaries GE Moore, Gottlob Frege, and Maurice Merleau-Ponty. Like the characters, these men labored to establish a particular understanding of the world. Some pages present diagrams or passages of algebraic logic. Descriptions of small, mysterious places-like pockets in Catherine's mind, pits in the ground, or a swallow's nest-serve as emblems of worlds intimated but beyond human knowledge.
Catherine's polymathic intelligence ranges from complex mathematics to animal sentience. She pictures hidden worlds in the sky, described as a "plane of translucent and unconnected fragments above them all." The narrative uses short, alternating chapters between the two time periods, creating a flickering sense of movement. The reviewer calls this a feat of engineering, allowing the story to cut between temporalities and philosophical traditions while handling distinct historical settings.
Narrative style and tradition
The novel does not feel abstruse to read, according to the source. Its mysteries are not meant to infuriate. When Catherine's father stakes his farm on American stock market investments, the story shows how floating abstractions tether to material realities. Duncan's novels, from his debut Love Notes from a German Building Site through The Gorgeous Inertia of the Earth, share a careful, patient narrative voice. While some earlier works leaned on psychological disintegration, here the conclusions are more definite, offering glimpses of characters' new worlds with economic gestures.
The book often reads as a realist Irish rural story, with hens underfoot, cold black tea, and drizzle. Catherine, dignified and marked by a bone-deep sadness from childhood tragedy, could almost be a William Trevor character. However, Duncan's fiction converges that tradition with a cerebral European mode drawn to philosophy, architecture, madness, and exile. The reviewer states, "I can't think of another writer who draws from the same seams in any comparable way."
The weight of precise detail
The prose is described as exceptionally straightforward. A passage detailing Alois making dinner is cited: he "sets a dark pot on his range to boil. He then lifts a skillet from the wall and begins to heat it up."
This physical attention is intense but not sustained, making the close descriptions seem weighted with something beyond themselves. The review questions whether the "tiny pantry" is contextual detail or a metaphor, suggesting a relation to Wittgensteinian language games. The precision feels suggestive, like a photorealistic still life where detail prompts meditation. In this novel, every half-inch cube of butter makes you wonder.
