'What Is Love? An Incomplete Map of the Metaphysics' is the second research paper developed under the aegis of this project. The paper will be appearing in the Journal of the American Philosophical Association, and a final draft is now online.
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.
