“We are intelligent beings: intelligent beings cannot have been formed by a crude, blind, insensible being: there is certainly some difference between the ideas of Newton and the dung of a mule. Newton's intelligence, therefore, came from another intelligence”

“Intelligence is being intelligent enough to know you're not so intelligent as you intelligently once thought.”

“There are three types of intelligent persons: the first so intelligent that being called very intelligent must seem natural and obvious; the second sufficiently intelligent to see that he is being flattered, not described; the third so little intelligent that he will believe anything. I knew I belonged to the second kind.”

“I don’t care about someone being intelligent; any situation between people, when they are really human with each other, produces ‘intelligence.”

“If human beings are the most intelligent creatures on earth, why is it that the other less intelligent creatures realise themselves in their group of spieces that they are the same despite the difference in colour or condition, while humam beings don't”

“All of us have worries. We worry because we are intelligent beings. Intelligence predicts, that is its essence; the same intelligence that allows us to plan, hope, imagine, and hypothesize also allows us to worry and anticipate negative outcomes.”
