A wide body of psychological research corroborates the claim that whether one’s life is (or will be) meaningful appears relevant to whether it is rational to continue living. This article advances conceptions of life’s meaningfulness and of suicidal choice with an eye to ascertaining how the former might provide justificatory reasons relevant to the latter. Drawing upon the recent theory of meaningfulness defended by Cheshire Calhoun, the decision to engage in suicide can be understood as a choice related to life’s (...) meaningfulness insofar as an individual can see no point in investing her agency in her anticipated future. These meaning-based reasons relevant to suicidal choice either cannot be reduced to the reasons of well-being that philosophers have typically used to analyse suicide decisions or at least forms a distinct class of reasons within those that contribute to well-being.

This entry begins by indicating respects in which the concept of life’s meaning has only recently become salient in English-speaking bioethical discussions and by clarifying what talk of ‘life’s meaning’ and cognate phrases mean, at least to most of the philosophers and bioethicists who have used them. This essay then addresses six major respects in which thought about what makes a life meaningful has influenced bioethics. The first four issues concern life and death matters for human beings, and specifically involve: (...) euthanasia and physician-assisted suicide, reproductive ethics, life extension, and transhumanism. The other two topics are about respects in meaningfulness figures into somewhat ‘less vital’ medical contexts, concerning ways in which promoting health is conceived either as a way to advance meaning or as in competition with the latter value. This essay concludes by offering a brief bird’s-eye reflection on the state of the field. (shrink)
