Peter Singer

It was wrong to capture wild animals and confine them in captivity for people to go and gawk at them. And that's basically how zoos got started. But once you do that, and once you have animals that have been bred in captivity, you're really stuck with them in some sense. You can't return them to the wild.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.

My father emigrated from Lithuania to the United States at the age of 12. He received his higher education in New York City and graduated in 1914 from the New York University School of Dentistry. My mother came at the age of 14 from a part of Russia which, after the war, became Poland; she was only 19 when she was married to my father.
