This document discusses open source and commons-based peer production. It describes peer production as large-scale collaboration that is decentralized and motivated by social factors rather than markets or management. Peer production enables modular, granular contributions that can be easily integrated at low cost. The document also discusses Ivan Illich's concept of "conviviality" as individual freedom through personal interdependence. Commons-based peer production can materialize virtues like autonomy, creativity, altruism, and cooperation. However, the relationship between peer production and virtues is not directly causal and remains normatively attractive rather than conclusively proven.
