Man does not learn. History is doomed to repeat itself. Always? Perhaps. But even so, the question remains, when this would be the case. It is my belief, that history cannot be stopped. What can be done with it, however, is delay it. Every time in our own lifes we are able to delay the inevitable. And maybe, just maybe, in time, humanity can break its own cycle.
Take note, I do believe in several basic formulas that can be named, but their expression in time changed, not to mention of new schemes being created with times marching on. No, there was and never had been a past-ages high technology civilization dying on Atlantis. Now get lost.
