 Topics (a) and (c)—what makes a minded being differ from a minded one, and what its properly mental content and activity extend to encompass—have evident connections with topic (b): the unity of the mental. For presumably a minded being will be one whose states have “mental content” and whose activities are properly mental or psychological in character; to decide what those contents and activities include will be to decide not only what is part of its mind, but also what puts something in the domain of the mental at all. Further, insofar as such boundaries of mind also mark boundaries of self (or person or psychological subject—however these categories are to be related)—we will find topics (a-c) closely related to topic (e)—regarding the constitution, continuity and situatedness of self.
