Here are the contexts of the quotes tweeted from @sueannbowling between September 18 and September 24, 2014. The first six are from Mort, by Terry Pratchett.
“Rather than drown in uncertainty it was better to surf right over the top of it.” One of the things Mort has learned as an apprentice to Death.
“If there’s one thing that really annoys a god, it’s not knowing everything.” Why the gods have not loosed an avalanche on the abbey of the Listeners.
“History has a habit of changing the people who think they are changing it.” Mort thinks he has changed history by preventing an assassination, but history is tougher than that.
“People just don’t see what their mind says isn’t there.” Cutwell is speaking to Mort, who already knows that.
“Better to be a dead queen in your own castle than a live commoner somewhere else.” The Royal way of looking at things, as Cutwell attempts to explain Keli’s attitude to Mort.
“Empaths were necessary, but they were not suited to rule.” Sue Ann Bowling, Tourist Trap. Part of Zhaim’s grievance against Roi.
