There may be fairies at the bottom of the garden. There is no evidence for it, but you can't prove that there aren't any, so shouldn't we be agnostic with respect to fairies?

Richard Dawkins

Everytime a child says 'I don't believe in fairies' there is a little fairy somewhere that falls down dead.

James M. Barrie

The fairies break their dances / And leave the printed lawn.

A. E. Housman
