Part of a special issue on the legacy of the Fluxus group. Variously described as a laboratory, a conceptual country, or a community, Fluxus is well known at least by name, but its central ideas and issues are overshadowed by a multiplicity of misleading or one-sided interpretations. According to its cofounder, Dick Higgins, it is a way of doing things, a tradition, and a way of life and death rather than a moment in history or an art movement. Instead of labeling it as a movement, it is better to examine the issues or themes that typify its experience, which include globalism, the unity of art and life, and intermedia. Aiming to provide an introduction to the rich network of its ideas, this issue seeks to reveal the sometimes hidden dimensions in what may appear as a well-understood phenomenon.
