Political legitimacy depends on constructing structures of well-founded trust [definitional]
Locke did not expect well-founded trust to be actualized at all frequently even in an essentially legitimate political society. But he thought that in political communities which were fortunate enough to be essentially legitimate the problems of political agency for all socially and politically active groups were always problems of how best to construct, reproduce, or repair structures of well-founded mutual trust.
