Safeguarding collective wisdom is a powerful tool for civilization to overcome the major upheavals ahead. Climate change, civil unrest, wars: How will we make it through the tough times that loom ahead of us? By remembering, Mary Soderstrom argues. Our time is the first in history that catastrophe has threatened societies, but, using examples from China, the Roman Empire, and North American Indigenous cultures, Soderstrom shows how memory can lead the way toward the future. Before We Forget examines how memory works in people, and then details how we store our collective memories in libraries and archives, as well as in the vastness of the electronic universe. In part an entertaining history of knowledge and where we keep it, Before We Forget allays fears and encourages people to develop strategies for safeguarding collective and individual wisdom, which we will need to meet the challenges ahead.
