Published for MoMA's retrospective exhibition and in collaboration with the artist, this volume presents new critical essays that expand on Piper's practice in ways that have been previously under- or unaddressed. Focused texts by established and emerging scholars assess themes in Piper's work such as the Kantian framework that draws on her extensive philosophical studies; her unique contribution to first-generation conceptual art; the turning point in her work, in the early 1970s, from conceptual works to performance; the connection of her work with her yoga practice; her ongoing exposure of and challenge to xenophobia and sexism; and the relation between prevailing interpretations of her work and the viewers who engender them.
