Definition of the problemAdvance directives involve evaluative assumptions about the further course of one’s life that can be more or less appropriate and thus call for ethical reflection. This contribution focuses on the basis and criteria of such assumptions. We argue that considerations regarding the temporal structure of a good life constitute a particularly relevant perspective in this context.ArgumentsEmpirical studies on the individual composition of advance directives point to the important role of personal values and life plans that can change (...) over time. Therefore, we first contextualize advance directives from the perspective of an ethics of the good life and then discuss their implications with regard to different levels of temporality, comprising fundamental parameters of human existence in time, cultural models of the life course, as well as narratives of the individual trajectory of life.ConclusionConceptions of a good life and its temporal structure represent an important perspective for drafting and interpreting advance directives. Their consideration provides a more nuanced understanding of the evaluative implications of advance care planning. This can benefit individual patients, service providers, as well as policy makers.
