Here again, it occurred to me, was the unique problem that faces my generation, the generation of those who had been, say, seven or eight years old during the mid-1960s, the generation of the grandchildren of those who'd been adults when it all happened; a problem that will face no other generation in history. We are just close enough to those who were there that we feel an obligation to the facts as we know them; but we are also just far enough away, at this point, to worry about our own role in the transmission of those facts, now that the people to whom those facts happened have mostly slipped away.
