“To think one thought meant thinking the opposite thought, and no sooner did that second thought destroy the first thought than a third thought rose up todestroy the second.”

“First Thoughts are the everyday thoughts. Everyone has those. Second Thoughts are the thoughts you think about the way you think. People who enjoy thinking have those. Third Thoughts are thoughts that watch the world and think all by themselves. They’re rare, and often troublesome. Listening to them is part of witchcraft.”

“First Sight means you can see what really is there, and Second Thoughts mean thinking about what you are thinking. And in Tiffany's case, there were sometimes Third Thoughts and Fourth Thoughts although these...sometimes led her to walk into doors.”

“Listen to your second thought, or the third might be too late.”

“Thought is the seed of action; but action is as much its second form as thought is its first.”

“It was knowing someone else thought about me for more than one second, maybe thought about me when I wasn't there.”
