The COVID-19 pandemic, Black Lives Matter movement and renewed action against climate change all highlight the increasing gulf between narrowly based dominant political ideologies and popular demands for social justice, global health, environmentalism and human rights. This book examines for the first time the exclusionary nature of prevailing political ideologies. Bringing together theory, practice and the relationship between participation, political ideology and social welfare, it offers a detailed critique of how the crucial move to more participatory approaches may be achieved. It is concerned with valuing people's knowledge and experience in relation to ideology, exploring its conventional social construction including counter ideology and the ideological underpinnings and relations of participation. It also offers a practical guide for change.
