True

"'That's too good to be true,' said Nanny.

'There are very few things good enough to be true,' said Diamond; 'but I hope this is. Too good to be true can't be. Isn't true good? and isn't good good? And how then, can anything be too good to be true?...'"

George MacDonald, from At the Back of the North Wind

Purpose

"The best thing you can do for your fellow, next to rousing his conscience is-not to give him something to think about, but to wake things up that are in him; or say, to make him think for himself."

-George MacDonald, from The Fantastic Imagination
