Based on Hannah Arendt’s notion of love, this article develops a life affirmative ethics, which we argue can guard against indifference and evil and enable ethical agency. In being the means through which existential journeys are made to what gave and gives birth to us, storytelling is important for such ethics. The love of our relations, communities, places, landscapes, oceans, family, people and animals is embedded in such storytelling. She referred to it as thinking—what she called a person’s two-in-one conversation with themself. In this storytelling, we engage in conversations with life. We use two stories of new sustainability managers to think through how love of the world—amor mundi—can help enable ethical agency in corporate contexts. Pondering over and thinking about the richness of life including pain, violence, struggle, conflict as well as joy and happiness are parts of an affirmative attitude to life that is part of maturing as a person, and which may help us learn to manage sustainably. Through Arendt, we learn that love is a question of mutual loving, where true solidarity with others relies on curious and compassionate thinking. This happens through revisiting our becoming and our experiences of the good life. Such thinking is the way in which we collect ourselves from dispersion, resist power relations and maintain a curious and caring relationship to the world’s plurality.
