This is a book born of long and deep reflection on its subjects' writings (especially Montaigne's), and attends to both the tiny stitches of an essay, play or fiction, and to the larger design. As Williams maps the linkages and the meanings to which they lead, he can listen with a tuner's sensitivity to the internal rhymes in a line of Racine and to their equivalents in Ted Hughes's rendering, or, zooming out, can give a sweeping overview of the poliical context. His methods persuasively combine material historicity with some inspiration from "universal" deconstructionism and psychoanalysis; the results are rich and layered, and show how barren theoretical purism can be.
