“In the whole history of the world there is but one thing that money cannot buy...to wit--the wag of a dog's tail.”
“Money will buy a pretty good dog, but it won't buy the wag of his tail.”
“Money will buy you a fine dog, but only love can make it wag its tail.”
“A dog wags its tail with its heart”.”
“our moral reasoning is plagued by two illusions. The first illusion can be called the wag-the-dog illusion: We believe that our own moral judgment (the dog) is driven by our own moral reasoning (the tail). The second illusion can be called the wag-theother-dog's-tail illusion: In a moral argument, we expect the successful rebuttal of an opponent's arguments to change the opponent's mind. Such a belief is like thinking that forcing a dog's tail to wag by moving it with your hand will make the dog happy.”
“Well, then,' the Cat went on, 'you see, a dog growls when it's angry, and wags its tail when it's pleased. Now I growl when I'm pleased, and wag my tail when I'm angry. Therefore I'm mad.”
