This study explores the potential of critical transformative learning for revitalizing citizen action, particularly action toward a sustainable society. Through an action research process with 14 university extension participants, it was found that a dialectic of transformative and restorative learning is vital for fostering active citizenship. This study also found that transformation is not just an epistemological process involving a change in worldview and habits of thinking; it is also an ontological process where participants experienced a change in their being in the world. As participants shifted into a new mode of relatedness with their material, social, and environmental realities, they sought avenues for socially responsible involvement as active citizens.
