There is a thread that connects everything that exists: the weave of nature, society, and culture. This fabric is vulnerable. Since the nineteenth century, we have considered it plausible to dominate everything: the laws of life, nature, societies, and markets. We thought that we could grow infinitely, and we tried. The result is the world we live in: the Anthropocene. The crisis will be increasingly deeper. We have lost the essence of what could facilitate the construction of a collective response: the essence of our being as humans. This book examines the role of education in building a more humane society. What does this society consist of? Is it possible to build it before it is too late? How can we have quicker transitions after the pandemic? What is the role of the younger generations? The author offers a panoramic view of the problem, but instead of venturing to give absolute answers, he invites us to construct a collective thought. A global educational crusade will be useful in order to rebuild us as societies and to change the paradigm of unlimited growth for one of a more humane and sustainable society.
