“If goodness has causes, it is not goodness; if it has effects, a reward, it is not goodness either. So goodness is outside the chain of cause and effect.”
“Nature is a good name for an effect whose cause is God.”
“cause and effect act in webs, not chains.”
“In the end, nothing is lost. Every event, for good or evil, has effects forever.”
“Don't wake me for the end of the world unless it has very good special effects.”
“Small causes can often have large effects. Smaller causes can have even bigger effects, and the very biggest effects frequently have no cause at all. Witness, for example, the world. It was created out of nothing, and that has made it the worst calamity the world has ever seen.”
