I'm often asked the question, "Do you think there is extraterrestrial intelli-
gence?" I give the standard arguments -- there are a lot of places out there,
and use the word *billions*, and so on. And then I say it would be astonishing
to me if there weren't extraterrestrial intelligence, but of course there is as
yet no compelling evidence for it. And then I'm asked, "Yeah, but what do you
really think?" I say, "I just told you what I really think." "Yeah, but
what's your gut feeling?" But I try not to think with my gut. Really, it's
okay to reserve judgment until the evidence is in.
