As an alternative to approaching Islam as an object for anthropological analysis, this article develops the idea of an anthropologist participating in conversations going on within an Islamic tradition. The idea of a conversation is developed through the ethical philosophy of Emmanuel Levinas and his ideal of knowing as an ethical relation with an infinite other. Levinas opposes a sterile and oppressive relation of 'totality', where the knowing self encompasses the other within concepts and thought that originate in the self, with a critical and creative relation of 'infinity', in which the alterity of the other is maintained and invites conversation that brings the self into question. In the article, recent disciplinary discussions of how anthropology should engage with alterity, which have been framed in terms of ontology and post-secular anthropology, are examined in the light of Levinas's ideal of knowing as ethical and critical practice.How can, or, perhaps more importantly, how should, anthropology engage with Islam? I was first prompted to revisit this problem by a response in the question-and-answer session following a talk I gave at a university anthropology department in the United States on the topic of Islam in Uzbekistan. The questioner, a Muslim, said that he had been offended by my presentation. I had been talking about lived experience as a site for the development of moral selves. A person comes to an understanding of what it is to be a Muslim, I had argued, through rituals and practices that refer to Muslim histories and sacred texts, but also in the ongoing flow of experience, in marrying off one's children successfully, helping a neighbour to build a house, participating fully in a sociality of neighbourhood and kinship, and, perhaps more problematically for my questioner, in dream or waking interaction with spirits, often in the context of illness, whether as a patient or a healer. I sought to engage sincerely with the experience of individual Muslims in Uzbekistan. But the questioner felt that I was misrepresenting what Islam is truly about, that I was presenting beliefs and practices that many Muslims would themselves view as humanly produced tradition, the misunderstandings or nonQur'anic practices of some Muslims, as standing for Islam itself.I was taken by surprise by the response because this is not a new problem and is one I thought had long been resolved. It was the central concern of disciplinary
