To begin at the beginning, one of the best-known C S Lewis quotes, "farther up and farther in," is taken from the end of the seventh Narnian Chronicle, The Last Battle, in which it is repeated several times (and is even used as a chapter heading.) A very similar expression was used by MacDonald in one of his own novels—also a fantasy, also towards the end, and also in the context of a spirit-soaring "good death." MacDonald's "farther in, higher up" is the likelier to have deeply influenced Lewis because Lilith was one of his favourite works, a fondness for which (if his biographer George Sayer is to be believed) seemed almost a passport to his intimate friendship.
