Abstract

Humans participate in an immense variety of relationships with other persons and other entities: human and nonhuman, living and nonliving, tangible and intangible, real and imagined. Participation in relationships is considered a key benchmark of personhood. Some of these relationships, particularly friendships, involve close emotional attachments, and some friendships have been described since antiquity as spiritual in nature. Different types of friendship depend upon factors such as proximity, social formality, physical intimacy, information exchanged, and the costs and benefits of maintaining the relationship. There are time‐extended processes and narrative practices involved in forming and dissolving relationships. A question is raised how androids (hypothetical humanoid robots that people would accept as equals in society) can participate in friendships with humans and other entities. This article explores the space of friendships with the aim of formulating guidelines for a computational model that can make explicit the information processing requirements and step‐by‐step processes involved with participating in the many different types of friendships, including those known as spiritual friendships.
