This chapter revisits the ethic of hospitality as a guiding ethic for education during the current climate crisis and other transgressions of planetary boundaries. Existing work on an ethic of hospitality has considered social inequalities that threaten newcomers’ hospitable reception but has, thus far, not been attentive enough to threats to the livability of the planet itself. This chapter recasts hospitality as a form of common decency and restraint by those in affluent regions, mainly in the global north. It presents “family hold back” as a scene of everyday hospitality that embodies this spirit of common decency. It then discusses how common decency has been taken up in moral theory, especially by Cheshire Calhoun and Todd May. It also discusses the challenges of grappling with justice not just to spatially distant others but also to temporally distant others, which is the central issue of intergenerational justice. This chapter argues that educational hospitality has to be lived in the spirit of the common decency of sharing the planetary home not only with those who are children today but also with those yet to arrive. With reference to Hannah Arendt’s work, this chapter argues that the enactment of hospitality in education requires today’s adults to take responsibility not only for representing the world but for showing our own contributions to ecological regeneration and climate change mitigation. Without such contributions, we fail at offering hospitality and lack credibility and authority in educating the next generation. This chapter closes by raising the question of an ethic of hospitality beyond its anthropocentric boundaries, in which hospitality can extend to other-than-human generations.
