I’m not too sure entirely what you’re trying to say here. At most all I see is the statement that without anything to experience then there is no experience. Which might be true enough, but I don’t really see how it’s relevant. At best I can see it as meaning that without experience there can be no action, but I don’t see how that means that action is necessary for experience. Even if it does, I still don’t see how it proves your point.
You say that death is equivalent to ‘no experience’ but that’s only true on an atheistic worldview. If we are talking about Heaven, then that statement is false. There is something to experience, namely, Heaven.
You also talk as if experience itself has no value and is only a means to an end (namely action), but you’ve provided no evidence to support this.
Your argument itself seems to have several other problems.
- Humans have limited experience
- Any type of limited experience will inevitably lead to misery.
- Heaven provides limited experience since we cannot have unlimited experience because we are not and will not be God.
4 . Since humans can only have limited experience even the limitless experience of heaven will eventually become misery.
- Thus, heaven is misery.
Your first premise, that humans can only have limited experience, only applies to this life. I see no reason to believe that humans in heaven will be so limited in our capacity to experience. It may be true that humans cannot have an actual limitless experience, that doesn’t mean that we lack the potential for infinite experience. Its the same thing as the difference between an actual infinite and a potential infinite, just applied to humans.
Your second premise is also suspect. Your sole proof for it is that in this life it is possible to, over time, lose interest in things that we enjoy. Or, to put it another way: since you get tired of experience in this life, that means that you’ll also get tired of experience in Heaven. But that isn’t necessarily true. The key problem is the phrase ‘over time’. You are implying that Heavenly time is the same as Earthly time, only longer. But eternity is not the same as infinite time .Eternity is, according to C.S. Lewis, the eternal present. And our own experience shows that joy - not joy remembered or joy anticipated, but joy experienced in the present, is anything but misery.
This calls into question your third (and forth) premise, since, if it is possible for humans to experience a potential unlimited experience, than this premise is false.
