This article raises questions about what the word 'knowledge' refers to. Drawn from some 40 years of collaborative work on knowledge democracy, the authors suggest that higher education institutions today are working with a very small part of the extensive and diverse knowledge systems in the world. Following from de Sousa Santos, they illustrate how Western knowledge has been engaged in epistemicide, or the killing of other knowledge systems. Community-based participatory research is about knowledge as an action strategy for change and about the rendering visible of the excluded knowledges of our remarkable planet. Knowledge stories, theoretical dimensions of knowledge democracy and the evolution of community-based participatory research partnerships are highlighted.
