Olafur Eliassona (TM)s large-scale installations addressing aspects of human perception are as fascinating as they are unsettling. Eliasson believes that art is a practice through which vital aspects of society and life may be examined, challenged, and renegotiated. Cultural practices such as art are not driven by capitalistic values, but operate through reflection on the values that define sociality, on the way that experience and ethics are intertwined, and ultimately on how subjectivity is defined. Eliassona (TM)s interest in architecture, space, time, and art thus comes from a fundamental interest in human beings and in our potential to re-evaluate the conditions that determine or influence our sense of subjectivity. Eliasson explores these aspects of his work in this volume which documents in detail three exhibitions: Your Light Shadow, Hara Museum, Tokyo; Notion Motion, Museum Boijmans Van Beuningen, Rotterdam, and The light setup, MalmA, Konsthall. This volume also contains a seminal text by the artist.
