This study focuses on examining the ideal and communal life of future society through literature by analyzing care ethics in Willa Cather’s O Pioneers!, The Professor’s House, and Death Comes for the Archbishop. As an ethical analysis that has been lacking in discussion about Cather’s works, it aims to shed light on the aspects that the main characters of the works practice the values of a virtuous human society and care by pursuing a co-existence life based on emotional exchanges with the surrounding people. In these three works, Cather notes that each of the main characters in the mainstream society practices his/her own virtues by having a complementary relationship with marginalized characters. He/She tries to communicate emotionally and commune with the surroundings in order to ultimately live a moral life as a right human being. Of course, in the process, the characters are directly involved in negative situations such as infidelity, evil, violence, jealousy, and feud, but they successfully practice their care ethics that can help overcome given difficulties and ensure human autonomy and welfare through trust and sympathy with the community. As such, care that can convey various lives of humans in stories is meaningful in that it can contribute to the completion of virtue in the end. Therefore, this paper observes the care aesthetics the characters embody focusing on their complementary lives, and further explores the potential for harmony and equality-oriented growth of the community that they can have a positive effect on the modern society.
