This book focuses on ageing as a topic of philosophical, theological, and historical anthropology. It provides a systematic inventory of fundamental theoretical questions and assumptions involved in the discussion of ageing and old age. What does it mean for human beings to grow old and become more vulnerable and dependent? How can we understand the manifestations of ageing and old age in the human body? How should we interpret the processes of change in the temporal course of a human life? What impact does old age have on the social dimensions of human existence? In order to tackle these questions, the volume brings together internationally distinguished scholars from the fields of philosophy, theology, cultural studies, social gerontology, and ageing studies. The collection of their original articles makes a twofold contribution to contemporary academic discourse. On one hand, it helps to clarify and deepen our understanding of ageing and old age by examining it from the fundamental point of view of philosophical, theological, and historical anthropology. At the same time, it also enhances and expands the discourses of philosophical, theological, and historical anthro­pology by systematically taking into account that human beings are essentially ageing creatures.
