A collection of stories by bioethicists writing about their own illnesses displays the importance of microethics. From this perspective, ethics happens not in the application of principles to specific decisions, but rather in the moment-to-moment flow of clinical interaction, as healthcare workers and patients make decisions, especially in their use of language. Microethical issues that are common to multiple stories are described as dense junctures of ethical concern. Three junctures are discussed in detail: conflicts between medical and patient rationalities, issues of how clinicians represent patients, and practices of truth telling. These junctures are illustrated with examples from the bioethicists’ personal stories of treatment.
