[Transgenerational solidarity: treatment and prevention in an expanded context]

This article searches for a common denominator for the requirements of that which therapy and prevention address in their broadest terms: 1. Genuine criteria of autonomous individuation in the context of real relationship that have to be sorted out vis-à-vis random internal relations that inform the private epistemologies of each partner's idiosyncratic goals. 2. The dialogue of mutual self-definition anchored in the balance of inherent commitments to mutual self-validation through fair give and take--the basis of relational ethics, i.e., responsibility for consequences to others. 3. The systemic regulation of behavioral patterns of marriages, parent-child relationships, nuclear and extended families, and larger community networks. 4. An intrinsic tribunal of transgenerational solidarity as the basis of prevention and as the manifestation of human species survival, e.g., concern about environmental health. 5. Negentropy as the "locomotive" of biological evolution and via ethics of receiving through giving to posterity, the guardian of both parent-child and peer relationships in a progressively automated world.
