It is easy for us to criticize the prejudices of our grandfathers, from which our fathers freed themselves. It is more difficult to search for prejudices among the beliefs and values we hold.

Those who lie and cheat, but do not believe what they are doing to be wrong, may be living according to ethical standards. They may believe, for any of a number of possible reasons, that it is right to lie, cheat, steal and so on. They are not living according to conventional ethical standards, but they may be living according to some other ethical standards.
Peter Singer
As far as food is concerned, the great extravagance is not caviar or truffles, but beef, pork and poultry. Some 38 percent of the world's grain crop is now fed to animals, as well as large quantities of soybeans. There are three times as many domestic animals on this planet as there are human beings. The combined weight of the world's 1.28 billion cattle alone exceeds that of the human population. While we look darkly at the number of babies being born in poorer parts of the world, we ignore the over-population of farm animals, to which we ourselves contribute...[t]hat, however, is only part of the damage done by the animals we deliberately breed. The energy intensive factory farming methods of the industrialised nations are responsible for the consumption of huge amounts of fossil fuels. Chemical fertilizers, used to grow the feed crops for cattle in feedlots and pigs and chickens kept indoors in sheds, produce nitrous oxide, another greenhouse gas. Then there is the loss of forests. Everywhere, forest-dwellers, both human and non-human, can be pushed out. Since 1960, 25 percent of the forests of Central America have been cleared for cattle. Once cleared, the poor soils will support grazing for a few years; then the graziers must move on. Shrub takes over the abandoned pasture, but the forest does not return. When the forests are cleared so the cattle can graze, billions of tons of carbon dioxide are released into the atmosphere. Finally, the world's cattle are thought to produce about 20 percent of the methane released into the atmosphere, and methane traps twenty-five times as much heat from the sun as carbon dioxide. Factory farm manure also produces methane because, unlike manured dropped naturally in the fields, it dies not decompose in the presence of oxygen. All of this amounts to a compelling reason...for a plant based diet.
Peter Singer
The prescription of the equality of human beings is not a description of an alleged actual equality among humans: it is a prescription of how we should treat human beings.
Peter Singer
If we have learned anything from the liberation movements, we should have learned how difficult it is to be aware of the ways in which we discriminate until they are forcefully pointed out to us. A liberation movement demands an expansion of our moral horizons, so that practices that were previously regarded as natural and inevitable are now seen as intolerable.
Peter Singer
We have to speak up on behalf of those who cannot speak for themselves.
Peter Singer
If our life has no meaning other than our own happiness, we are likely to find that when we have obtained what we think we need to be happy, happiness itself still eludes us.
Peter Singer
Putting yourself in the place of others...is what thinking ethically is all about.

Their reliance on biblical quotations does not augur well for their for their openness to moral reasoning....
