This book is written by William Strauss and Neil Howe. It explores the concept of generational cycles and proposes a theory that history unfolds in a recurring and predictable pattern that every span lasts around a lifetime roughly 80-100 years which consists of four turnings. These turnings are driven by generational shift and societal and cultural transformations. The book was written in 1997, at which point the authors wrote that we were approaching the Fourth Turning which is the life changing period of crisis that marks every saeculum in history.
Trying to understand the current geopolitical situation, its essential to know some history of the current most powerful nation on earth, America. This post is nothing more than just a summary and my thoughts after reading the book. The full breadth of ideas within the book will amaze you. I highly recommend this book for those who loves to know history and excited for the future and at the same time prepare for it.
