The Journal of Practical Ethics recently posed 20 hardball questions to Peter Singer about his philosophy. It is a terrific insight into his thinking as his long career draws to a close.
About utilitarianism: Why do many intelligent and sophisticated people reject utilitarianism? Some people give more weight to their intuitions than I do—and less weight to arguments for debunking intuitions. Does that reduce my confidence in utilitarianism? Yes, to some extent, but I still remain reasonably confident that it is the most defensible view of ethics. I don’t know if everyone will accept utilitarianism in 100 years, but I don’t find the prospect frightening. It would only be frightening if people misapplied it, and I do not assume that they will.
On critics: There have been many critics of my views about euthanasia for severely disabled infants. I had some good discussions with the late Harriet McBryde Johnson, who was not a philosopher but a lawyer who had a rich and full life despite being born with a very disabling condition. As long as she was alive, when I wrote anything on that topic, I wrote with her potentially critical response in mind.
The objective truth of morality: You could just say “these are my normative views, and I’m going to treat them as if they were true, without thinking about whether moral judgments really can be objectively true.” If you do that, then in practice your decisions will be the same whether or not moral judgments can be objectively true. But given that I think morality is highly demanding, it becomes easier to say that, since morality is so highly demanding, and there is nothing irrational about not doing what morality demands, I’m not going to bother doing what I know to be right.
