This paper is based on research into the Treatment Action Campaign (TAC) in South Africa. The research investigated whether, through being active members of this social movement, HIV-positive activists learn things they could not otherwise learn about their status and the epidemic, and how they put such knowledge to use. We show how activists develop a critical understanding of the underlying causes of their ill health and its link to economic poverty and global politics. The paper concludes by suggesting that adult educators can assume direct responsibility for poverty reduction by working in and with social movements.
