Bonhoeffer's New Beginning investigates the ethics of making new beginnings after devastating moral rupture. The work argues that new beginnings must be made in order to sustain the fundamental convictions that it is good to exist and that life in the world with others should be loved without exclusion. Bonhoeffer's ethics of new beginning is set in conversation with the thought of four moral philosophers, Friedrich Nietzsche, Hannah Arendt, Jonathan Glover, and Jonathan Lear. DeCort argues that Bonhoeffer's ethics of new beginning opens and energizes a more promising, world-affirming moral vision with radical hope for new beginnings vis-à-vis the perceived absence of God in the face of devastation.
