Abstract

In a 2020 paper, 37 authors, all researchers and students in aging biology, pointed out a general lack of consensus in their field, “even on the most fundamental questions”. They evoked a “problem”, for which a solution has yet to be found. But what exactly does this lack of consensus specifically refer to and why should it be inherently problematic? Here, I would like to explore three distinct philosophical reactions when dealing with this issue. First, I will assess the extent to which this lack of consensus can be taken as evidence that science, in a sense, needs philosophy. Then, I will examine how it may be related to the particular nature of the aging phenomenon, which both science and philosophy can help describe and understand. Finally, I will show that this lack of consensus could also be considered, not as a problem, but as an opportunity to question the role of pluralism and the importance of ambiguity in science in general, and in aging biology in particular.
