" In an earlier stage of our development most human groups held to a tribal ethic. Members of the tribe were protected, but people of other tribes could be robbed or killed as one pleased. Gradually the circle of protection expanded, but as recently as 150 years ago we did not include blacks. So African human beings could be captured, shipped to America, and sold. In Australia white settlers regarded Aborigines as a pest and hunted them down, much as kangaroos are hunted down today. Just as we have progressed beyond the blatantly racist ethic of the era of slavery and colonialism, so we must now progress beyond the speciesist ethic of the era of factory farming, of the use of animals as mere research tools, of whaling, seal hunting, kangaroo slaughter, and the destruction of wilderness. We must take the final step in expanding the circle of ethics. - "

" At least ten times as many people died from preventable, poverty-related diseases on September 11, 2011, as died in the terrorist attack on the World Trade Center and the Pentagon on that black day. The terrorist attacks led to trillions of dollars being spent on the ‘war on terrorism’ and on security measures that have inconvenienced every air traveller since then. The deaths caused by poverty were ignored. So whereas very few people have died from terrorism since September 11, 2001, approximately 30,000 people died from poverty-related causes on September 12, 2001, and on every day between then and now, and will die tomorrow. Even when we consider larger events like the Asian tsunami of 2004, which killed approximately 230,000 people, or the 2010 earthquake in Haiti that killed up to 200,000, we are still talking about numbers that represent just one week’s toll for preventable, poverty-related deaths — and that happens fifty-two weeks in every year.

" The merely conscious being does not have a preference for continued life. Perhaps while having a pleasurable experience it has a preference for that experience to continue, or while having a painful experience it has a preference for that experience to end, but it will not have any preferences for the long-term future, and the desires it has do not survive periods of sleep or temporary unconsciousness, because unlike a self-aware being, it has no conception of its own future existence after a period of sleep. Thus if we are concerned only about the thwarting of preferences, for a merely conscious being, painless killing and administering an anesthetic seem to be equivalent. Killing does not thwart any more desires than putting the being to sleep. The being will be able to continue to satisfy its preferences after it awakes, but from the being's subjective perspective it is as if a new being, with new preferences, came into existence. "
