In this collective writing, leading scholars of United States and global history, sociology, and philosophy of education critically examine what it means to ‘never forget’ global war and violence in education. While 9/11 serves as one case, scholars reflect more expansively on the history of war, violence, and civil society, the dream of a world without nations, and the vital need for education for global understanding and action. How can we learn from history and understand its importance today? How can we shift out of cycles of racist, ethnonationalist, and xenophobic violence and warfare through education policy, pedagogy, and curricula? Authored by diverse global experts, this collective text can serves as a resource and foundation for deeper future studies (i.e., a special issue and book project) that further reflect on war, terrorism, and education.
