Extremist ideas thrive on the certainty they engender in their followers. Undermining that certainty is crucial to their defeat. The scholarship on show in this book is therefore vital: it shows that liberalism is not a Western, Christian or atheist construct. The authors writing here demonstrate that Islam is not only compatible with liberalism, but is inherently liberal. The battle against Islamist extremism must be led by the communities most directly affected. This includes Muslims themselves. This book provides ammunition to those who wish to battle the claim that Islam and freedom are incompatible.
