 Large parts of Stein’s treatise are devoted to further specifying the “structure” of communal experiences (1922: 112–122[133–145]), the “elements” it contains (such as imaginations, categorical acts, intentional feelings, etc.) (1922: 122–139[145–165]), the mechanisms integrating the individual experiences into the unified communal stream (1922: 139–147[165–175]; 159–163[191–196]), and finally its own personal, psychic and spiritual life (1922: 163–199[196–238]) (see also Burns 2015; Caminada 2015). Roughly, the communal stream has a temporally structured internal coherence, with its own “associative”, “motivational”, and “causal” mechanisms conjoining the individual experiences into an experientially coherent “integrate” (1922: 141–147[167–175]). Experiences also affect one another by “psychic” and “volitional causation” (1922: 159–163[191–196]). Accordingly, the communal stream exhibits its own life-feelings as well as psychic and spiritual life-power (1922: 145–147[172–175]; 167–185[201–203]). Communities can be more or less productive, energized, etc., depending on the contribution of the life-power of the participating individuals. In turn, the communal life-power feeds back on the individuals’ life-power (see Müller 2020).
