I’m honestly fine with you calling it whatever you like, but one of the following situations must obtain:
- We cease to exist at some point.
- We exist forever, but at some point cease be consciously aware.
- We are at least intermittently aware of our existence forever.
Case 3 has two possible sub-cases: 3A, where (after some specific point) we enjoy all the parts of our eternal existence that we’re cognizant of, or 3B, where we don’t enjoy it all.
Personally, if you’re in 3A, I think it’s fair to call that heaven. Anything else, not so much. And I would call both of cases 1 and 2 annihilation scenarios.
There is absolutely nothing I know of that I could do forever and still be happy doing it - I toggle activities every two to ten hours. But the point is that whatever you’re doing, it can’t possibly be productive or novel forever. So you better like spinning your wheels for nostolgia’s sake.
Fortunately for me I probably could cycle through the same several entertainment options forever, thanks to my relatively bad memory making things seem fresh again over and over. Er, I do get to keep my bad memory, right? If I didn’t have it eventually I’ll have seen and done it all and there’ll be nothing new under the sun.
Less than infinite time.
But even if there was an infinite list of things to know, it would inevitably start showing patterns and repetition and stop being novel - or it would just be random slush with no meaning and become boring as a whole.
(Plus doing all that learning sounds boring. Some people can stay in school forever; not me.)
Or, alternatively, there hasn’t been much said because there isn’t much to say. It’s a fictional concept that sounds great when casually mentioned (“It’s a place where good people are happy forever! And everybody gets a pony!”) but like many fictional concepts it doesn’t hold together under scrutiny the way real things do.
But like I said, I’m willing to carefully consider any model of heaven presented to me. I’d be happy to consider it; as you can probably tell I find these sort of philosophical thinking games entertaining. But “One exists! Go dig for it yourself! It’s stored right next to the unicorns!” doesn’t count as presenting a model to me.
