“And how do you know that you're mad? "To begin with," said the Cat, "a dog's not mad. You grant that?" I suppose so, said Alice. "Well then," the Cat went on, "you see a dog growls when it's angry, and wags it's tail when it's pleased. Now I growl when I'm pleased, and wag my tail when I'm angry. Therefore I'm mad.”

“Alice didn't think that proved it at all; however, she went on: 'And how do you know that you're mad?''To begin with,' said the Cat, 'a dog's not mad. You grant that?''I suppose so,' said Alice.'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.''I call it purring, not growling,' said Alice.”

“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.”

“Cheshire Puss,' [Alice] began, rather timidly, "`But I don't want to go among mad people,' Alice remarked. Oh, you can't help that,' said the Cat: `we're all mad here. I'm mad. You're mad.' How do you know I'm mad?' said Alice. You must be,' said the Cat, `or you wouldn't have come here.' Alice didn't think that proved it at all; however, she went on `And how do you know that you're mad?' To begin with,' said the Cat, `a dog's not mad. You grant that?' I suppose so,' said Alice. 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.”

“A dog wags its tail with its heart”.”

“But I don’t want to go among mad people," Alice remarked."Oh, you can’t help that," said the Cat: "we’re all mad here. I’m mad. You’re mad.""How do you know I’m mad?" said Alice."You must be," said the Cat, "or you wouldn’t have come here.”
