I believe life has no absolute purpose. This is probably a costly belief compared to other, more rosy (i.e. religious) beliefs with which I am very familiar.
Nonetheless, I hold the belief I do, despite it's negative consequences (emotional, motivational, psychological, etc.), because I'm compelled to believe this way based on the evidence.
As I said, I don't see any reason someone couldn't believe in a non-honest god. I've talked to deists who don't consider "honesty" a characteristic that applies to the sort of hyper-powerful entity they believe created all things.
If our conscious experience is a simulation, then are the creators of that simulation (i.e. the gods) being "honest"?
I think you are factually mistaken about whether life has a purpose. Of course to see whether we actually disagree about this I would have to know why you added the word "absolute" there. But it looks to me like you just agree with Eliezer that reality in itself is indifferent. As I have said in other threads, I think reality in itself is good. Evidence that reality is purposeless, for me, would be a reality where there are no tendencies. Of course it is hard to imagine such a world, and it may be entirely impossible. But there is nothing strange...
