It is Wright’s contention that only by understanding and ultimately breaking from the patterns of progress and disaster that humanity has repeated around the world since the Stone Age can we avoid the onset of a new Dark Age. Wright illustrates how various cultures throughout history have literally manufactured their own end by producing an overabundance of innovation and stripping bare the very elements that allowed them to initially advance. Wright's book is brilliant; a fascinating rumination on the hubris at the heart of human development and the pitfalls we still may have time to avoid.
