What Is Love? An Incomplete Map of the Metaphysics

The paper begins by surveying a range of possible views on the metaphysics of romantic love, organizing them as responses to a single question. It then outlines a position, constructionist functionalism, according to which romantic love is characterized by a functional role that is at least partly constituted by social matters (social institutions, traditions, and practices), although this role may be realized by states that are not socially constructed.
