Pagden cites this passage in Spanish Imperialism, 70. 8 In his later treatise, "Del Commercio del Regno di Napoli" (1740), Doria mentioned trust in relation to civil law and referred to this as fede pubblica. While he suggests that fede pubblica needs a foundation in the private good, "La legge civile c'insegna questa massima e cioè: bonum publicum praefertur bono privato," he does not make a more elaborate distinction between fede privata and fede pubblica.
