Why does agency-the capacity to make choices and to act in the world-matter to us? Why is it meaningful that our intentions have effects in the world, that they reflect our sense of identity, that they embody what we value? David Kyuman Kim addresses these crucial questions by uncovering the political, moral, philosophical, and religious dimensions of human agency. Through a critical engagement with the work of theorists such as Judith Butler, Charles Taylor, and Stanley Cavell, Kim argues that late modern and postmodern agency is found most effectively at work in what he calls "projects of regenerating agency" or critical and strategic responses to loss. Agency as melancholic freedom begins and endures, Kim maintains, through the moral and psychic losses associated with a broad range of experiences, including the moral identities shaped by secularized modernity and the multifold forms of alienation experienced by those who suffer the indignities of racial, gender, class, and sexuality discrimination and oppression. Kim calls for renewing the sense of urgency in our political and moral engagements by seeing agency as a vocation, where the aspiration for self-transformation and the human need for hope are fundamental concerns.
