“Intelligence is the capacity to know what we are doing and instinct is just instinct. The results are about the same.”

“When I learned about this, I was told that it was “instinct.” (“Instinct” continues to be the explanation of choice whenever animal behavior implies too much intelligence.) Instinct, though, wouldn’t go very far in explaining how pigeons use human transportation routes to navigate. Pigeons follow highways and take particular exits, likely following many of the same landmarks as the humans driving below.”

“Nature never appeals to intelligence until habit and instinct are useless. There is no intelligence where there is no need of change.”

“Our capacities, our instincts for this our present sphere are but half developed. Let us be completely natural; before we trouble ourselves with the supernatural.”

“All things resist destruction, according to their capacity. Rocks, pebbles, diamonds. Unity is instinctive to being.”

“That's what everyone thinks--they think being a cop is about punishing people for doing wrong. But that's not true. You know it isn't. It's about believing in people, believing in the good. In the will of people to do what's right despite their own instincts.”
