Science is atypical because it is cultivated with communal participation from throughout the world. This global formation has evolved recently. It originates in the institutionalization of a cosmopolitan tradition in Europe. The cosmopolitan orientation and the perceived usefulness of the European tradition promoted its adoption and institutionalization in the non-Western civilizations. A global institutional frame, including a global science policy regime, sustains communal participation in world science. Participation is described in terms of individual, national, and global communalformations.
