Is This the End?
Brian and Molly are talking about the sudden death of a mutual friend. “I’m still shocked
to think that Karl is gone,” Molly says.
“I know you were quite close to him,” Brian says. “But do you think in some sense Karl

1. N • I
“If memory goes with the brain,” Molly replies, “then I wonder if the consciousness you
speak of is in any way your consciousness. But setting that aside, are there any reasons for
thinking that the soul is immortal?”

“Fine,” Molly says. “But what makes you think that you have a nonmaterial soul in the
first place?”
“Well,” Brian replies, “according to Descartes, I am essentially either a mind or a body.

“Your argument is so abstruse that I don’t find it very persuasive,” says Molly, as she
scratches her head. “I think the evidence is overwhelming that humans are the product of
