Created from Animals: The Moral Implications of Darwinism (1990), p. 5
“Let us consider first the view that it is always wrong to take an innocent human life. We may call this the “sanctity of life” view. People who take this view oppose abortion and euthanasia. They do not usually, however, oppose the killing of nonhuman animals—so perhaps it would be more accurate to describe this view as the “sanctity of human life” view. The belief that human life, and only human life, is sacrosanct is a form of speciesism.”

“Consider also our approach to the sanctity and value of human life.”
Nobel lecture (2005)
Context: Consider also our approach to the sanctity and value of human life. In the aftermath of the September 2001 terrorist attacks in the United States, we all grieved deeply, and expressed outrage at this heinous crime — and rightly so. But many people today are unaware that, as the result of civil war in the Democratic Republic of the Congo, 3.8 million people have lost their lives since 1998.
Are we to conclude that our priorities are skewed, and our approaches uneven?
