The Guestbook Project is an ongoing artistic, academic, and multi-media experiment in hospitality. Directed by Irish philosopher Richard Kearney and sponsored by Boston College, the project's core themes are the relationship between host and stranger; violence and reconciliation; the citizen and the alien.
