From the intro to "God Bless You Dr. Kevorkian" by Kurt Vonnegut

Some of you may know that I am neither Christian nor Jewish nor Buddhist, nor a conventionally religious person of any sort.

I am a humanist, which means, in part, that I have tried to behave decently without any expectation of rewards or punishments after I'm dead. My German-American ancestors, the earliest of whom settled in our Middle West about the time of our Civil War, called themselves "Freethinkers," which is the same sort of thing. My great grandfather Clemens Vonnegut wrote, for example, "If what Jesus said was good, what can it matter whether he was God or not?"

I myself have written, "If it weren't for the message of mercy and pity in Jesus' Sermon on the Mount, I wouldn't want to be a human being. I would just as soon be a rattlesnake."

I am honorary president of the American Humanist Association, having succeeded the late, great, spectacularly prolific writer and scientist, Dr. Isaac Asimov in that essentially functionless capacity. At an A.H.A. memorial service for my predecessor I said, "Isaac is up in Heaven now." That was the funniest thing I could have said to an audience of humanists. It rolled them in the aisles. Mirth! Several minutes had to pass before something resembling solemnity could be restored.

...

So when my own time comes to join the choir invisible or whatever, God forbid, I hope someone will say, "He's up in Heaven now." Who really knows? I could have dreamed all this.

My epitaph in any case? "Everything was beautiful. Nothing hurt." I will have gotten off so light, whatever the heck it is that was going on.
