What, if anything, lasting and remaining was "won" from the welter of struggles through the 1960s to the early 1970s?  Nothing that I can point to.

  Instead, human nature remains mortal and ever subject to having to relearn the "lessons" of the past.  Fortunately, on the upside, it also implies that our errors aren't permanently fixed either--unless, of course, they amount to our own species-ending errors.

  So, either I don't understand what "we only have to win once" means or, if I understand it, it's a dangerously mistaken idea.  Whatever we "win" has to be preserved carefully and transmitted, or it will surely be lost.
