If possessing a higher degree of intelligence does not entitle one human to use another for his or her own ends, how can it entitle humans to exploit non-humans?

To protest about bullfighting in Spain, the eating of dogs in South Korea, or the slaughter of baby seals in Canada while continuing to eat eggs from hens who have spent their lives crammed into cages, or veal from calves who have been deprived of their mothers, their proper diet, and the freedom to lie down with their legs extended, is like denouncing apartheid in South Africa while asking your neighbors not to sell their houses to blacks.

An animal experiment cannot be justifiable unless the experiment is so important that the use of a brain-damaged human would be justifiable.

I have never really been fond of animals. I certainly wasn't an 'animal lover' when I became involved in the movement. I just came to be persuaded that animals should be treated as independent sentient beings, not as means to human ends.

I'm such an advocate for animal rights and environmental rights.

The time will come when men such as I will look upon the murder of animals as they now look on the murder of men.
