“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. -”

“Our gods, if we choose to believe in them, must be forced to live up to ethics that far surpass our own human standards. If they fall short of the ethical conditions we place upon ourselves, what use are they to us - except to rationalize our own failures?”

“Thinking like ethical people, dressing like ethical people, decorating our homes like ethical people makes not a damn of difference unless we also behave like ethical people.”

“… architects are not acting for themselves but on behalf of others, and this means acting ethically. It is to ethics that we now turn.”

“We are faced this year with the choice between the "work ethic" that built this Nation's character and the new "welfare ethic" that could cause that American character to weaken.”

“Civilization is very fragile, all it takes is a few decades of chaos for us to forget humanity and turn into animals. Our base natures can take over very fast. We can forget that we are sentient beings, with laws and codes and ethics.”
