"This chapter will focus on the theorizing of communication and social change. It will argue that theory must enable people to know the world. It will also argue the limits to token participation and the unsustainability of "behavioral change communication'' that is theorized outside of structures, power flows, and cultures. Using the Right to Information movement in India as a case study, this chapter will explore grounded meanings of "voice" and "participation'' and will argue the need for a theory of communication for social change that is informed by people's needs and struggles. If theory is a set of principles informed by and drawn from observations of everyday needs and practice, its explanatory power is bound to remain consistent over time. Theory offers us a framework for knowing the world and the validation of concepts that are critical to apprehending and making sense of reality. I argue in this chapter that the Right to Information movement in India gives opportunities to explore communication and social change theory from the bottom up." (Abstract)
