In the wake of the Coronavirus pandemic, intergenerational solidarity and responsibility have become central points of reference in public discourses. However, the use of these concepts is often unclear and ambivalent: On one hand, older people are described as a vulnerable group whose protection requires sacrifices on the part of younger generations, e.g., regarding individual freedom and economic welfare. On the other, they appear as dispensable individuals that should relinquish their claims for the sake of the young and their future prospects. Our contribution offers an analysis of intergenerational solidarity and responsibility in public discourses on COVID-19. The leading question is how both concepts are used and how the corresponding claims can be justified or criticized. We first give an overview of notions of intergenerational solidarity and responsibility in current debates. In the next step, we provide a moral philosophical clarification of both concepts and their normative presuppositions. We then conduct a descriptive ethical discourse analysis of pertinent cases from three areas of European discourse: politics, civil society, and mass media. The analysis focuses on politico-moral claims and their normative premises, ambiguities, and biases. We argue that the discourse involves assumptions about old age and generational relations that need further clarification and justification. An analysis of intergenerational solidarity and responsibility in times of COVID-19 can help understand the dynamics of social cohesion in late-modern societies.
