David Attenborough quote: “The Roman public's thirst for blood and pleasure in witnessing pain seems to have been unquenchable and without limit."…”

“On the surface it may seem that wars are caused by economic and political questions, but in fact they are caused by our wholesale slaughter of animals. The laws of justice are inexorable, and human beings are going to have to pay with their own blood … We kill animals, but nature is an organic whole, and by killing animals we are, as it were, affecting certain glands in that organism. When this happens, the balance of the organism is disrupted, and it is not surprising that before long war breaks out among men. Yes, human beings have slaughtered millions of animals for their meat, without realizing that on the invisible plane those animals are linked to other human beings, and it is they who will now have to share the fate of the animals. When we slaughter animals we are slaughtering human beings. Everybody agrees that it is time to establish the reign of peace in the world, that there must be no more wars. Yes, but war will go on just as long as we continue to slaughter animals, because by destroying them we are destroying ourselves.”

“The dictator is the one animal who needs to be caged.”

Zulfikar Ali Bhutto (1928–1979) Fourth President and ninth Prime Minister of Pakistan

Context: Tin-pot dictators have ravaged Asia, Latin America and Africa. In the aftermath, they have done more to promote communism than the works of Marx and Engels, Lenin and Mao. They are the worst tyrants of the post-colonial period. They have destroyed time-honoured institutions and treated their people like animals. They have caused internal divisions and external confusion. The dictator is the one animal who needs to be caged. He betrays his profession and his constitution. He betrays the people and destroys human values. He destroys culture. He binds the youth. He makes the structure collapse. He rules by fluke and freak. He is the scourge and the ogre. He is a leper. Anyone who touches him also becomes a leper. He is the upstart who is devoid of ideals and ideology. Not a single one of them has made a moment's contribution to history.

“Animals who die for your dinner table die alone, in terror, in sadness and in pain. The killing is merciless and inhumane. … Animals suffer from pain and fear just as much as you do. Most spend their last hours locked in a truck, packed into a cage with hundreds of other terrified animals and then cruelly pushed into a blood soaked death chamber. Animals which are a year old are often far more rational – and capable of logical thought – than six-week-old babies. Pigs and sheep are far more intelligent than small children.”

“They were going to look at war, the red animal — war, the blood-swollen god. And they were deeply engrossed in this march.”

Stephen Crane book The Red Badge of Courage

Source: The Red Badge of Courage (1895), Ch. 3
Context: The line, broken into moving fragments by the ground, went calmly on through fields and woods. The youth looked at the men nearest him, and saw, for the most part, expressions of deep interest, as if they were investigating something that had fascinated them. One or two stepped with overvaliant airs as if they were already plunged into war. Others walked as upon thin ice. The greater part of the untested men appeared quiet and absorbed. They were going to look at war, the red animal — war, the blood-swollen god. And they were deeply engrossed in this march.
