A necessary warning from Victor Davis Hanson

I always find cautionary tales like this one from good classicists/historians troubling but necessary.

Think back to the Roman era of the "Five Good Emperors" - between A.D. 96-180 under the reigns of Nerva, Trajan, Hadrian, Antonious Pius and Marcus Aurelius - when all problems of the turbulent past at last seemed to have been solved. There was a general peace, ever more prosperity from Mediterranean-wide trade, and a certain boredom and occasional cynicism among the Roman elite. Few then had any idea that three centuries of war, revolution, poverty and scary emperors like Commodus and Caracalla awaited their descendants - all a prelude to a later general collapse of Roman society itself.

In our own new age of war, terrorism, huge debt, high-priced gas and frightful weapons and viruses that we try to ignore, we should remember that civilization's progress is not always linear. The human condition does not inevitably evolve from good to better to best, but always remains precarious, its advances cyclical.

Too many of us take civilization, the comforts of modernity, and prosperity for granted, and with each year we become less vigilant about protecting them.
