“It is not worth while to try to keep history from repeating itself, for man’s character will always make the preventing of the repetitions impossible.”
It is a question philosophers have debated for millennia; is history a straight line or does humanity run around in circles. Mark Twain, being our American Philosopher, addressed that question too. And judging from what’s happend in the world since he wrote these words, it would seem as if he got it right.
