Imagination grows by exercise and contrary to common belief is more powerful in the mature than in the young.

The imagination is truly the enemy of bigotry and dogma.

You always have to defend the imagination against idiots.

Many people would have to hang by their teeth from a frayed cord suspended by a paper clip from a leaking hot air balloon over the Grand Canyon in order to feel what I feel standing on the third step of a stepladder trying to put millet in the bird feeder.

There's a great fear of the imagination. It's a dangerous thing. It's out of control, it's subversive.
