The domestic animals do not manifest hatred and cruelty toward each other; that is the attribute of the wild and ferocious beasts. In a flock of one thousand sheep you will witness no bloodshed. Numberless species of birds are peaceful in flocks. Wolves, lions, tigers are ferocious because it is their natural and necessary means for obtaining food. Man has no need of such ferocity; his food is provided in other ways. Therefore it is evident that warfare, cruelty and bloodshed in the kingdom of man are caused by human greed, hatred and selfishness.
