Personal sexual intimacy is the private analog of civic trust relations.

Evidence

This relationship, in his view — and he wrote a treatise to demonstrate that women were the equal, or at least the near equal, of men — was one of the most significant in any society, since for Doria sexual relations were in the private domain what civil relations were in the public: opportunities for trust and ‘conversation’, which can easily collapse into honour and secrecy (1973: 48). — Diego Gambetta, Trust - Making and Breaking Cooperative…, 1816

Categorization

• DEFINE: Doria’s distinction between trust/conversation and honour/secrecy—the private-domain twin of civic trust—is core to the reader’s Luhmann/Hardin synthesis.
• XREF: Directly maps onto Hardin’s trust-as-encapsulated-interest argument and Luhmann’s familiarity: when ‘conversation’ collapses into honour and secrecy, observability and trust degrade.
