While trying to read up on pantheism in general, I kept coming across this talk of 'scientific pantheism'. As near as I can tell it's mostly for atheists who want to say they're "spiritual".
One thing I repeatedly bumped into was this sort of talk:
Pantheism believes that we live on in nature where we are re-absorbed, but also in people's memories and in the achievements we leave behind. Therefore we have a powerful incentive to be good and kind to people, and to achieve lasting good in our lives. The kinder we are, the more good we do, the longer will be our "afterlife" in people's memories. If we do harm, then our memory will be execrated.
Yeah... kind of missing where the powerful incentive part shows up.
First there's the angle of, "Oh boy, so if I really do good and luck favors me, I'm remembered for 100 or 1000 or 10000 years instead of 10 years, before being utterly forgotten. Well hey, sign me up!" Not to mention, fictional characters probably have more of an "afterlife" than most people by this yardstick. Compare the number of guys who know and have memories of Joe Barbera to Scooby freaking Doo.
Second, if merely being remembered is desired, then Judas, Hitler, Napoleon and others have some stellar advice on achieving a long-lasting afterlife, and it's not really clear why happy memories are better than ones of hate or fear. This sort of pantheism conceivably can come in misanthrope versions, but this just gets nicely glossed over. I recall how General Woundwort ended up in Watership Down, what the memory was of him, and the comment of what Woundwort would have possibly thought of that very legacy.
Third, to the idea that "we live on in the memories of our loved ones" sort of talk. As mentioned prior, what sort of memories we leave or what we should want to leave is an open question. Also unappreciated is this: It's not just our loved ones who remember us. It's also the people who hate us. What, did the people who thought say.. FDR was an asshole forget all about him when he died? There are people who think that of FDR *now*. How's his afterlife doing?
Mind you, these criticisms are largely restricted to materialistic pantheisms. Idealistic, dualistic, even simulation theoristic versions are another matter, at least on this front. But I have a natural distaste for empty poetics, and that seems to be all that this type of pantheism has going for it.
