My life’s far from perfect, but I don’t find it miserable. I’m sorry to hear you do.

Yes reincarnation has a certain appeal, especially if people come back as animals appropriate to their behaviour. That has a certain poetic justice. I can just imagine a naturalist calling out excitedly to his colleague:

“What is it Ted?”
“It’s this priapulid worm… it bears a striking resemblance to Jerry Falwell!”

Really? Isn’t this one life miserable enough?

But if I must live forever, I’d pick reincarnation over Christianity’s heaven.
(1) I get recycled (yeah!)
(2) I get the chance to fix my mistakes
(3) I get to go somewhere else and to have problems with different people.
