"It is just like man's vanity and..." - Quote by Mark Twain
It is just like man's vanity and impertinence to call an animal dumb because it is dumb to his dull perceptions. Heaven is by favor; if it were by merit your dog would go in and you would stay out. Of all the creatures ever made he (man) is the most detestable. Of the entire brood, he is the only one...that possesses malice. He is the only creature that inflicts pain for sport, knowing it to be pain. The fact that man knows right from wrong proves his intellectual superiority to the other creatures; but the fact that he can do wrong proves his moral inferiority to any creature that cannot.

“We are all here on this planet, as it were, as tourists. None of us can live here forever. The longest we might live is a hundred years. So while we are here we should try to have a good heart and to make something positive and useful of our lives. Whether we live just a few years or a whole century, it would be truly regrettable and sad if we were to spend that time aggravating the problems that afflict other people, animals, and the environment. The most important things is to be a good human being.”
“It is easy to make plans in this world; even a cat can do it; and when one is out in those remote oceans it is noticeable that a cat's plans and a man's are worth about the same. There is much the same shrinkage in both, in the matter of values.”
“Oh, that dog! Ever hear of a German Shepherd that bites its nails? Barks with a lisp? You say, "Attack!" And he has one. All he does is piddle. He's nothing but a fur-covered kidney that barks.”
