“But things are not as they teach us- for the world is hollow and I have touched the sky!”

“Science can teach us, and I think our hearts can teach us, no longer to look around for imaginary supporters, no longer to invent allies in the sky, but rather to look to our own efforts here below to make the world a fit place to live.”

“All of the world's religions have important things to teach us, and they are not as different from each other as some would have you believe.”

“It was as if his point of view had, within seconds, gone from that of an ant to that of an eagle.For the sky was hollow, and the world was round.”

“Thanks for teaching us to talk. Thanks for teaching us to be of the world and in the world and to make our way. Thanks for teaching us to be alive! And thanks for staying inside of us.”

“If history teaches us one thing, than that history teaches us nothing.”
