This edited collection considers whether it is possible to discern how the level of ideology is affected by radicalization. In other words: what happens in the minds of people before they decide to use political violence as means to attain their goals? Also this book asks: what has to happen in the minds of people in order to preclude them from using political violence as a way of attaining their goals? This volume unites scholars from several disciplines and perspectives from a number of different geographical, social and cultural contexts with the overarching aim to refine our understanding of what 'radicalization' actually implies.
