“Of all the creatures that were made he [man] is the most detestable. Of the entire brood he is the only one — the solitary one — that possesses malice. That is the basest of all instincts, passions, vices — the most hateful…He is the only creature that inflicts pain for sport, knowing it to be pain…Also — in all the list he is the only creature that has a nasty mind.”

“Of all the animals, man is the only one that is cruel. He is the only one that inflicts pain for the pleasure of doing it.”

“Man is the only creature endowed with the power of laughter; is he not also the only one that deserves to be laughed at?”

“Of all the creatures that man kills for his amusement there is only one that he kills out of hatred—other men. Man hates nothing as much as himself. That is why war is called the leprosy of the human soul.”

“Man is the only creature who refuses to be what he is.”

“The human being is a most curious creature. He thinks he has got one
soul, and he has got dozens.”

“Man can be the most affectionate and altruistic of creatures, yet he's potentially more vicious than any other. He is the only one who can be persuaded to hate millions of his own kind whom he has never seen and to kill as many as he can lay his hands on in the name of his tribe or his God.”

“He could not be mistaken. There were no other eyes like those in the world. There was only one creature in the world who could concentrate for him all the brightness and meaning of life. It was she. It was Kitty.”

“He was less afraid of gentlemen than of most other kinds of men; for instinct told him that, however detestable a gentleman's personal character might be, he was usually not inclined to be censorious or even inquisitive about the conduct of his fellow-creatures.”

“Of all God's creatures, there is only one that cannot be made slave of the leash. That one is the cat. If man could be crossed with the cat it would improve the man, but it would deteriorate the cat.”
