What does it mean to become older? This question cannot be answered by biology or sociology alone but must be addressed by studying how aging appears to aging persons and to others who encounter them. The paper presents the outline of such a phenomenological analysis of aging. In contrast to a problematic tendency to reduce phenomenology to the study of first-person experience, it is suggested that aging should be understood as a complex process comprising of both subjective and objective (mental, (...) social and biological) elements, and as partly transcendent to experience, that is, not completely transparent to the aging person. In this it resembles physical and other “transcendent” objects as described by early phenomenologists like Husserl. It is further shown how Marcel Proust’s elaborate description of aging in the last volume of his Remembrance of Time Past can support and contribute to such an analysis, and how it is supported or at least compatible with findings from contemporary gerontology and cognitive psychology.
