Our history to date has been one long procession of construction and destruction. Now that we are able to put an end to all human presence on Earth, the future of our species depends largely on political choices. It is therefore essential to think about a political system within which our future can be protected in the long term. After an overview of some of the major problems that threaten humanity – environmental, but also economic, military, and social – this book examines whether modern democracies offer an appropriate framework for dealing with them. In particular, it attempts to restore hope in a promising future, in a new era that each of us can help usher in, and proposes a political structure conducive to our survival in the age of “omnicide”, which we entered on August 6, 1945 when we dropped the first atomic bomb on Hiroshima.
