I'm afraid an afterlife would not leave Dennett in good humor.
Similar to Vonnegut's joke at a memorial service for Asimov at the American Humanist Society: "Isaac is up in Heaven now".
It's amusing that when I searched for the exact quote just now, I found this HN comment from 2011, on the "in memoriam" thread for Dennett's fellow horseman:
Even if he was wrong about it, it's important to air the thinking around it regardless of belief.
The proposition, for example, that consciousness is basically an illusion without empirical basis, one would have to take up as belief, I guess (paradoxically), since to most of us, that would seem like gaslighting (i.e., "if your conclusion is that Descartes was wrong and that we can't even know we are conscious, then I beg to differ")
I think that I think that I think, therefore I think that I think I am
It's kind of interesting that this is still on HN front page at the same time:
