Radical Neo-Enlightenment is a spirited response to the multiple and accelerating crises we face today. The provocative and ambitious work contends that we require a “radical neo-Enlightenment” to counter these systemic crises. The driving idea is that Reason must now be reclaimed as a powerful force for positive social change. Along the way, the book criticizes philosophy’s failings and restores its noble compulsion to change the world. Radical Neo-Enlightenment then criticizes conventional religion and advances a reconstructed faith that would be an ally of socially-transformative Reason. It then marks out practical core steps that would lead to rational global transformation. While the book is introductory and accessible in scope and style, it confronts and develops the thought of some of the most important subversive thinkers of the past and present.
