The theme for The Watchman's Rattle can be summed up in the story of the sophisticated and scientifically developed Mayan society: Unproven beliefs became the substitute for facts. Once this happens, as the practice of beliefs cannot result in real solutions, the inevitability of failure takes place, and disaster is the only outcome.
Our inherent hubris about our being as evolved as we can possibly ever be, is another message that one can take from The Watchman's Rattle. If we do not heed the lessons of the past, if we continue to ignore all the warning signs that threaten human existence-such as global recession, powerful pandemic viruses, terrorism, rising crime, climate change, rapid depletion of the earth's resources, nuclear proliferation, and failing educational systems-we are doomed to extinction. However, if we do pay attention, Costa lays out a plan that places us in an excellent position to change a repetitive pattern of decline.
This is an excellent book, rich with challenging thoughts as well as perceptive solutions. Costa offers excellent research in this fully developed dissertation on the warning signs and potential solutions to human and global destruction.
Highly recommended.—Geri Spieler, New York Journal of Books
