For the past thirty years, Howard Caygill has been a distinctive and radical voice in continental philosophy. For the first time, this volume gathers together Caygill's most significant philosophical essays, the majority of which are not freely available and many of which are previously unpublished. Here, a major philosopher is at work, offering rich, rigorous and politically-engaged readings of canonical and lesser-known figures and texts. From Kant and Frantz Fanon to Herman Kahn, founder of the Hudson Institute, Caygill uncovers the untapped resources that the history of philosophy provides for contemporary thought, whilst critically pushing beyond the limits of the tradition. Divided into two parts, the first part of the collection reveals the philosophical backdrop to Caygill's acclaimed study of political resistance, On Resistance: A Philosophy of Defiance (2015), whilst the second part sees Caygill further develop his account of resistance through wide-ranging analyses of contemporary culture. Exploring numerous subjects, including Nietzsche, metaphysics, radical politics, and digital resistance, to name but a few, Force and Understanding introduces readers to the orienting themes of Caygill's thought and provides the opportunity to engage with one of the most astute, learned, and critical philosophical minds around. Ringing true and brilliant and crystal clear, Force and Understanding confirms what we have long thought and have yet to say: Howard Caygill is to be counted among the great thinkers of our time.
