The Center for Consciousness Studies (CCS), based at the University of Arizona, was formed in 1998 with a seed grant from the Fetzer Institute. The 1994 Tucson conference on "Toward a Science of Consciousness" is widely regarded as a landmark event, and the subsequent series of biennial conferences in Tucson organized by the Center have attracted extraordinary international, interdisciplinary interest. The Center is a unique institution whose aim is to bring together the perspectives of philosophy, the cognitive sciences, neuroscience, the social sciences, medicine, and the physical sciences, the arts and humanities, to move toward an integrated understanding of human consciousness. The Center is unique in its broad-spectrum approach. Other groups tend focus either on cognitive neuroscience, philosophy or purely phenomenal experiential approaches, whereas the Center not only integrates these areas, but "thinks outside the box" of conventional wisdom which has thus far, at least, failed to make significant breakthroughs. The Center has also inspired other groups such as the Association for the Scientific Study of Consciousness who organize other conferences.
