“Kindness” is gentleness, consideration, care for others. It is related to “kinship”—the genetic and affective bonds among parents, children, brothers, and sisters. By way of “kind,” meaning “species” or “breed,” it expands the reach of those bonds to what Montaigne (in Florio’s translation) calls “the general throng.” The word “kindness” incites us to think about how human virtues, which usually stand apart from the natural world, might be rooted in our kinship with all the other animals. The Tempest is a key text for thinking about the history and the great utility of kindness as a transspecies virtue in the twenty-first century. This chapter makes its case for animal virtue by telling the story of the key arc of action in the play itself and by recounting a story about how the author of the chapter, at a workshop with actors and scholars, was terribly unkind toward Caliban and what he learned from his own lack of animal virtue.
