“The heart of a man is a small thing but it desires great matters. It is not big enough for a dog’s dinner but the whole world is not big enough for it. Man spares nothing that lives; he kills to feed himself, he kills to clothe himself, he kills to adorn himself, he kills to attack, he kills to defend himself, he kills to instruct himself, he kills to amuse himself, he kills for the sake of killing. From the lamb he tears its guts and makes his harp resound; from the wolf his most deadly tooth to polish his pretty works of art; from the elephant his tusks to make a toy for his child.(...)And who will exterminate him who exterminates all others?”
