One Thing I Know is Pati Hill's third novel, first published in 1962, when she was forty-one and had just given birth to her first and only child. It is the last novel she wrote before claiming to "quit writing in favor of housekeeping".

Written in the purest tradition of American coming-of-age stories, One Thing I Know follows a sixteen-year-old girl, Francesca Hollins, as she discovers an unexpected taste for autonomy. The bravado of her affirmation cannot mask the seriousness of her conviction: "One thing I know, I will never be in love again." Francesca's journal begins with this statement, and neither Danny, a young boyfriend already haunted by bourgeois dreams, nor her mother, a woman she believes lacks all imagination, can convince her otherwise. The novel recounts how Francesca discovers an unexpected definition of her independence, something Diane Arbus perceived when she wrote to Hill: "I am more than ever convinced and maybe [Francesca] is too, that people are born old and that life has to be lived backwards and there is no convenient shortcut like forwards."

The reprint of Pati Hill's 1979 book, composed of images and texts by Hill through which she intended to contextualize and explain her working methodology to Jill Kornblee, her New York gallerist.

Published on occasion of Pati Hill's first posthumous solo exhibition at Kunstverein München in 2020.

Pati Hill (1921, Ashland, Kentucky – 2014, Sens, France) left behind an artistic output spanning roughly 60 years and encompassing various disciplines. Untrained as an artist, she began to use the photocopier as an artistic tool in the early 1970s and continued to do so until her death, leaving behind an extensive oeuvre that explores the relationship between image and text. In addition to this comprehensive body of xerographic work, she published four novels, a memoir, several short stories, artists books, and poetry. Drawing also became an essential part of her practice.

By using the copier—a machine that was stereotypically linked to secretarial work and thus to feminized labor—to trace everyday objects such as a comb, a carefully folded pair of men's trousers, or a child's toy, Hill developed an artistic practice that programmatically translated invisible domestic labor into a visual and public language. Through her use of this reproductive apparatus, she created a model of artistic production that critically opposes the convention of individual expression as well as the supposed neutrality of technologically produced images.
