“Sometimes a man wants to be stupid if it lets him do a thing his cleverness forbids.”

“All great events hang by a single thread. The clever man takes advantage of everything, neglects nothing that may give him some added opportunity; the less clever man, by neglecting one thing, sometimes misses everything.”

“Things that would have made fame of a less clever man seemed tricks in his hands. It is a mistake to do things too easily.”

“And this shows that sometimes people want to be stupid and they do not want to know the truth.”

“You aren't stupid, Lillian,' said Uncle Victor, smiling and shaking his head, 'but sometimes the things you do are.”

“I'm out to change people's attitudes about them. Wolves are a whole lot more than just predators who feast on a rancher's herd. They're smart and clever and loyal and courageours, and sometimes they do really stupid, silly things, just like people.”
