This paper makes the case for including "critical harmony" as a complement to justice within civic education. The concept of harmony is significant for civic education because it acknowledges the crucial role that relationships play in society--an important moral, ethical, and social ideal in many cultures around the world. Harmony must also incorporate a critical dimension, however, by embracing conflict and tension, valuing difference and diversity, and striving for balance among divergent voices. By using examples of public issues such as housing and gender identity to illustrate the relational dimension of public policy, this paper argues that the concept of critical harmony can contribute to a more comprehensive foundation for students' deliberation of civic issues.
