Identity politics have taken a strong hold on modern society, in particular online on social media platforms. But to what extent have they contributed to human flourishing? Have they changed the world for the better, and to what extent? David Pilgrim explores identity politics as a ''curate''s egg'': good and bad in parts. The good, that they shine light on topics that may previously have been neglected. The bad, their tendency towards absolutism and premature certainties. The world is nuanced and contradictory, and our awareness of it is highly partial. Identity politics are an inadequate response to that complexity and mystery of life. They take away the need to give free expression to all views, including those we may not only disagree with but might also find offensive. Pilgrim re-establishes a realist objection to strong social constructivist arguments within social science about gender, sexualities, and putative moral panics. This accessible book is a must-read for anyone with an interest in contemporary policy formation or reform. It will appeal to students and professionals from the fields of sociology, politics, social policy, social work, philosophy, mental health, and public health could use this book.
