One can trust someone in matters of love but not in money matters; one can trust his knowledge but not his skill, his moral intention but not his ability to report objectively, his taste but not his discretion. The reason for this specificity can be simply that trust was learned in this restricted sphere and has foundered in other respects. It may, however, also go back to a selective interest of the system to which the parties concerned belong and which even structures the learning process itself.

DEFINE: Clarifies that trust is not a general trait but is differentiated by specific domains (love, money, knowledge, skill), with causes ranging from where it was learned to system-level structures.
