Painter, sculptor, writer and philosopher Lee Ufan (born 1936) first came to prominence in the late 1960s as one of the major proponents of the Japanese avant-garde group Mono-ha. Japan's first contemporary art movement to gain international recognition, the Mono-ha school of thought rejected Western notions of representation, choosing to focus on the relationships of materials and perceptions rather than on expression or intervention. A new edition of a collection of writings first published in 2004, this volume features previously unpublished essays from 1967 to 2007 and a recent interview with Hans Ulrich Obrist. This edition has been published by Lisson Gallery and the Serpentine Galleries on the occasion of Lee Ufan's 2018 outdoor commission Relatum-Stage at Serpentine Galleries, London.
