A critic can only review the book he has read, not the one which the writer wrote.

Mignon McLaughlin (1913–1983) was an American journalist and aphorist best known for her concise, epigrammatic observations on art, love, and everyday life, many of which were collected in her books of maxims. This remark belongs to her recurring theme that communication is inherently imperfect: what an author intends and what a reader receives are never identical. In the mid‑20th‑century American literary scene—shaped by mass-market publishing and increasingly prominent reviewing culture—McLaughlin’s line functions as a wry reminder that criticism is inevitably mediated by the critic’s own experience, expectations, and interpretive habits rather than being a transparent report on authorial intention.

The aphorism draws a sharp distinction between the author’s act of creation and the reader’s act of reception. McLaughlin suggests that a review is always of the critic’s encountered text—filtered through attention, taste, and prior beliefs—not of the ideal work the author imagined or attempted to produce. The point is not that criticism is useless, but that it is necessarily subjective and partial: every reading is a reconstruction. Implicitly, the quote cautions writers against expecting perfect understanding and cautions readers to treat reviews as accounts of one person’s reading, not definitive judgments on the work’s “true” meaning.
