This article provides a critique of the monolithic accounts that define justice in terms of a single and often inappropriate goal. By providing an array of real examples, I argue that there is no simple definition of justice, because allocations that express justice are governed by a variety of reasons that reasonable people endorse for their saliency. In making difficult choices about ranking priorities, different considerations have different importance in different kinds of situations. In this sense, justice is a conclusion about whether an allocation reflects the human interests and priorities that are at stake. The article describes how several principles of justice have a legitimate place in medical allocations. To achieve justice within medical practice, professionals should focus on the human interests and compelling reasons for prioritizing specific principles within their specific medical domain.
