What can you ever really know of other people's souls — of their temptations, their opportunities, their struggles? One soul in the whole of creation you do know: and it is the only one whose fate is placed in your hands. If there is a God, you are, in a sense, alone with Him.
C. S. LewisThe fundamental laws are in the long run merely statements that every event is itself and not some different event.
