This article argues for communication for social change theory tobe based on a theory of knowledge, a specific understanding of process that feeds into practice, a knowledge of structures, a specific understanding of context and flows of power. It highlights the example of the Right to Information Movement in India as an embodiment of meaningful practice that was in itselfa response to the felt needs of people. It argues that the RTI movement provided opportunities to understand Voice as a practice and value through indigenous means, specifically through the mechanism ofthe Jan Sunwai (Public Hearings). It argues that when local people are involved in articulating ‘needs’, there will be scope for the sustainability of the practice of communication and social change and opportunities to theorise from suchpractice.
