 For Stein, the solidarity required for communal life is experientially grounded. Members of a community can only constitute a true community of solidarity if they are bound together by so-called “communal experiences” (Gemeinschaftserlebnisse), and jointly constitute a so-called a “supra-individual” (überindividuell) or “communal stream of experiences” (Erlebnisstrom der Gemeinschaft) (1922: 112–122[133–145]). This stream has its own motivational and psychic-causational laws (1922: 140–148[167–175]) and its own life-power (1922: 167–174[201–210]).
