In this article I draw on personal experience to explore the kinds of relationships that can develop between human and nonhuman animals. The first part of the article describes my encounters with wild baboons, whom I studied in East Africa over the course of many years. The baboons treated me as a social being, and to gain their trust I had to learn the troop's social conventions and behave in accordance with them. This process gave me a feeling for what (...) it means to be a baboon. Over time, I developed a sense of belonging to their community, and my subjective identity seemed to merge with theirs. This experience expanded my sense of the possible in interspecies relations. The second part of the article describes a mutual exploration of such possibilities in my relationship with my dog, Safi. I describe how Safi and I co-create systems of communication and emotional expression that permit deep 'intersubjectivity', despite our very different biological natures. In my relationships with baboons, dogs, and other animals, I have encountered the presence in another of something resembling a human 'self'. I emphasize the importance of recognizing and honoring this presence in other animals as well as in humans. (shrink)
