Open Ecological Technology's Golden Means

Aristotle observed that every virtue names a mean between two vices — one of deficiency, one of excess. Courage is not the absence of fear nor reckless abandon but the calibrated optimum between them. This document applies that structure to the design of open ecological technology, asking: what does it mean for a tool to be good, not merely functional? Illich names the conviviality threshold; OSE operationalizes village-scale production. OET extends both — toward cooperative and gift relations between users, toward the sovereignty of the user over the systems they depend on, toward design that matures alongside the living systems it inhabits, and toward the restraint to know when a tool should do less. The lineage runs through Kropotkin, Bookchin, the Burning Man and hacker traditions, EFF, Cory Doctorow, permaculture, and Daoist thought. The lineage is plural; the framework is OET's own.

Virtues of Convivial Tool Design

Each virtue names the design optimum; the vices name failure modes in either direction. Use as a scored evaluation rubric in OET design reviews.

Virtues of Convivial Society

The same doctrine applied at the level of social relations and energy structure, after Illich's threshold argument.
