Here are a couple of quotes for you that may be apropos - you be the judge:

"Those who cannot remember the past are condemned to repeat it."
George Santayana, The Life of Reason, Volume 1, 1905
 

"More than any other time in history, mankind faces a crossroads. One path leads to despair and utter hopelessness. The other, to total extinction. Let us pray we have the wisdom to choose correctly."
Woody Allen (1935 - )
