And this I believe: that the free, exploring mind of the individual human is the most valuable thing in the world.

And this I must fight against: any idea, religion, or government which limits or destroys the individual.
~ East of Eden
by John Steinbeck
"And what, incidentally, do you think integrity is? The ability not to pick a watch out of your neighbor's pocket? No, it's not as easy as that. If that were all, I'd say ninety-five percent of humanity were honest, upright men. Only, as you can see, they aren't. Integrity is the ability to stand by an idea. That presupposes the ability to think. Thinking is something one doesn't borrow or pawn."
~ The Fountainhead
by Ayn Rand
His life has been spent in devotion to ideas. The passions of his brain have consumed the passions of his body.
~ The Triumph of the Egg (Seeds)

by Gilbert Parker
"And people laugh at me because I use big words. But if you have big ideas you have to use big words to express them, haven't you?"
~ Anne of Green Gables
by Lucy Maud Montgomery
"Is it not? Is it not? Breadth of view, my dear Mr. Mac, is one of the essentials of our profession. The interplay of ideas and the oblique uses of knowledge are often of extraordinary interest."
~ The Valley of Fear
by Sir Arthur Conan Doyle
