'In this masterful work, Six ideas that threaten the World, Professor Winston Langley, a prolific writer, gives us a detailed meditation on the state of the world which is hurdling towards destruction. He offers us insights into how we placed ourselves in this dangerous location, and our individual and collective destinies to overcome our dark situation with hope and action guided by the quest for justice. ' -- Professor Teodros Kiros, Harvard Summer School, and producer of The Kiros Report. 'The author brings his broad historical knowledge to reflect on the major issues of our time. He does so in an engaging manner, giving us a survey that is at once accessible to students and stimulating to the general reader.' -- Victor Wallis, professor, Liberal Arts & Sciences, Berklee College of Music. 'Ideas, indeed, do matter. Winston Langley, a longtime senior administrator in higher education and scholar of international relations, probes six key ideas with widespread ramifications for the human condition. This book is an opportunity for readers to learn from and think with Langley, particularly amidst rapid advances in artificial intelligence that are facilitating the rethinking of ideas and attendant actions across the world.' -- Neil Roberts, Williams College
