Authority
Three topics have dominated philosophical discussion of authority: the nature of authority, the point of authority, and the sources of authority.
The Nature of Authority
In providing an account of the nature of authority, the focus in this entry will be on de jure practical authority, though the differences between de facto and de jure authority and between theoretical and practical authority will also be briefly considered at the end of this section.
What is authority? Authority is a relational matter: A has authority over B with respect to some domain D. What follows is first a consideration of items A, B, and D that enter into this relationship, and then of the nature of the relationship among them.
With respect to A: while A need not be a person, it must be something that can have a say-so—that is, it must be the sort of thing about which one can truly assert "A says that B must ϕ." So, A can be a natural person, or a corporate person, or an institution, or a text. With respect to B: while B need not be a natural person, B must be the sort of thing that exhibits agency.
