Neither the third nor the fourth age: viewing old age through the philosophical lens of ambiguity.

This paper argues that the philosophy of ambiguity, associated with Maurice Merleau-Ponty and Simone de Beauvoir, provides a helpful framework for understanding the complex and paradoxical nature of old age outside the dominant categories of the 'third' and 'fourth' ages. Building on philosophical literature in cultural gerontology including that focused on the 'art of living' and other approaches that draw on existentialist thought, it suggests 'ambiguity' as a theme that has been overlooked in such literature. The advantage of this approach is that it can accommodate contradictory elements and thus underpin an integrated approach to old age. At the same time, in distinguishing between ontological and social dimensions of ambiguity, the conceptual framework offers a new perspective on ageism that can help clarify the distinction between ageism as oppression and the negative aspects of deep old age itself. The paper is structured as follows. After making the case for the value and importance of 'ambiguity' as a framework for viewing old age, I set out the key aspects of this philosophy as found in the work of Merleau-Ponty and particularly Beauvoir. I then apply this framework to a discussion of two literary memoirs of deep old age, by Diana Athill and Florida Scott-Maxwell respectively. I argue that the picture of old age which emerges contrasts with the hegemonic discourses enframed by successful ageing and frailed old age and offer the possibility not only of a true appreciation of old age but also of a more meaningful life course itself.
