Today's dose of Pratchett Preachin' comes from 'Mort':

"History isn't like that. History unravels gently, like an old sweater. It has been patched and darned many times, reknitted to suit different people, shoved in a box under the sink of censorship to be cut up for the dusters of propaganda, yet it always – eventually – manages to spring back into its old familiar shape. History has a habit of changing the people who think they are changing it. History always has a few tricks up its frayed sleeve. It's been around a long time."

— Terry Pratchett, Mort
