ABSTRACT
The work of Peter Singer cover a wide range ethical issues, from animal liberation to euthanasia (including infanticide) and from globalization to the workings of George W. Bush's mind. When Singer speaks of the intelligence of animals, of their susceptibility to suffering, and of their capacity for empathy, his examples are apes and chimpanzees, animals that most closely resemble human beings. Racism has many manifestations, one of which is the taboo against interbreeding and marriage between members of different races. It is perhaps racism's deepest taboo. If the analogy holds, speciesism would entail a taboo against interbreeding between, say humans and chimpanzees, which anti-speciesists would want to combat, just as an anti-racist would fight against proscribing marriage between a white person and a black person. Singer takes up the challenge or appears to take it up.
