“That will be her undoing," gasped Artemis, already suffering under the weight of the flak jacket. "Artemis Fowl will never be."
"I thought you were Artemis Fowl the Second?" said Holly.”

“Radomosity, thought Artemis. And he felt like weeping.”

“Remember the pain?' thought Artemis. I hate myself. I really do.”

“Quickly, Holly," said Artemis urgently. "Follow those bubbles."

Holly opened the throttle. "Now there's an order I never thought I'd hear from you.”

“Really, I'm trying to care, Artemis, really. But I thought it was all supposed to be over when the fat lady sings. Well, she's singing, but it doesn't appear to be over”

“I hate you! (Artemis)
Oh, please don’t get my hopes up. You almost gave me a hard-on with that thought. At least tell me this time your hatred will last more than five minutes. (Acheron)”

“Thought is the thought of thought.”

“Thoughts of such magnificent vigor began to think their own thoughts-and their thoughts thought thoughts. As if in divine astonishment and surprise, All That Is began to listen, and began to respond to these generations of thoughts and dreams, for the thoughts and dreams related to each other also.”

“Of all the thoughts that rise in the mind, the thought 'I' is the first thought.”
