This essay considers Richard Zaners storytelling in Troubled Voices as a form of possibilizing which uses the stories to exemplify important moral themes such as contingency and freedom. Distinguishing between activities of moral discovery through the telling of a story and posing in the sense of writing to tell the moral of the story, I suggest that something crucial goes on for Zaner in his own tellings. Several of the more insistent implications Zaner reveals about the moral relationships encountered in the activity of clinical ethics consultation are examined in that light, especially regarding this question: is it more beneficial, or harmful, to articulate elements of core meanings and values that are entailed in individual viewpoints, which, prior to an ethics consultants participation, may have remained unspoken and possibly unacknowledged?
