" Maybe you could drive yourself crazy trying to chart backward all the causes and effects, all the ends and means, tracing everything to some original sin that may or may not have actually occurred but that people accepted as true, or true enough. Maybe staring into the eyes of all that history was a dangerous thing to do, as her mother had calmly warned her. Maybe you were supposed to move forward armed with just enough history to help you figure out the present without obsessing over the past. But how much was enough? Where was the gray area between ignorance and obsession? "
