The Life-Force is a sort of tame God. You can switch it on when you want, but it will not bother you. All the thrills of religion and none of the cost. Is the Life-Force the greatest achievement of wishful thinking the world has yet seen?
C. S. LewisIn Charn [Jadis] had taken no notice of Polly (till the very end) because Digory was the one she wanted to make use of. Now that she had Uncle Andrew, she took no notice of Digory. I expect most witches are like that. They are not interested in things or people unless they can use them; they are terribly practical.
