> And yet, as Sartre shows us in No Exit, it is the very presence of other humans and our being forced to view ourselves from the perspective of others that causes us so much existential dread and pain.
I've never been entirely clear on whether Sartre intended this or not, but it always seemed glaringly obvious to me that the problem in Huis Clos was not that they were trapped for eternity with other people: it was the specific other people they were trapped with. People who magnified all their own flaws and threw them back in their faces.
If, instead, you were bound for eternity to people with whom you shared mutual respect, understanding, and commitment to each other's happiness, that would be heaven.
It is not truly that "hell is other people", whatever Sartre might say. Isolation is the worst punishment we have in this lifetime. Being condemned to an eternity of isolation would truly be hell.
Even if you started out with people you couldn't stand, and spent aeons torturing each other, what's to say you couldn't then come to some form of co-commitment to happiness with them?
Heaven and hell are defined by how we interact with the people around us.
