Love is the motive, but justice is the instrument.
Just Mercy“Love is the motive, but justice is the instrument.” appears as the book’s epigraph, attributed to Reinhold Niebuhr. Its decisive distinction joins an inward ethical purpose to an outward means: love supplies the motive, while justice is the instrument through which that purpose is pursued.
Wording and Meaning
The sentence is balanced around a contrast. “Motive” names the reason for action; “instrument” names what is used to act. By assigning love and justice different roles rather than treating them as alternatives, the epigraph presents justice as a means of giving moral purpose practical form.
Placement and Function
Placed before the contents, the epigraph frames the book before its narrative begins. Its compact formulation establishes a relation between feeling and action, but the supplied text does not elaborate on Niebuhr’s meaning or specify how particular episodes interpret the line.
