There’s no question of your working out the entire future of the Galactic Empire, you know. You needn’t trace out in detail the workings of every human being or even of every world. There are merely certain questions you must answer: Will the Galactic Empire crash and, if so, when? What will be the condition of humanity afterward? Can anything be done to prevent the crash or to ameliorate conditions afterward? These are comparatively simple questions, it seems to me.
