Until rather recently, philosophy, when practiced as a way of life, was, for most, a communal enterprise of mutually reinforced personal cultivation. In these times of social isolation, including in academic philosophy itself, it is time, yet again, to revitalize this lost, but vital, intercultural mode of philosophy. This volume characterizes a neglected communal mode of philosophy — the philosophical community — by describing the constellation of metaethical principles (general, axiological, cultural, and dialectical) that cultivates its values. The book draws on examples from across the globe and history, including interviews of adherents of living philosophical communities.
