Law is culture, and culture is law. Given by the ancestors and cultivated over millennia, Indigenous law defines what it is to be human. Complex and evolving, law holds the keys to resilient, caring communities and a life in balance with nature. Marcia Langton and Aaron Corn show how Indigenous law has enabled people to survive and thrive in Australia for more than 2000 generations. Nurturing people and places, law is the foundation of all Indigenous societies in Australia, giving them the tools to respond and adapt to major environmental and social changes. But law is not a thing of the past. These living, sophisticated systems are as powerful now as they have ever been, if not more so. Law: The Way of the Ancestors challenges readers to consider how Indigenous law can inspire new ways forward for us all in the face of global crises.
