I am still confused.
Let's take a person, say, Alice. Alice believes in Jesus. In fact, she believes in Jesus with all her heart and Jesus' love is the bright spot in her otherwise dreary life of quiet desperation. She gets a lot of happiness from her religious beliefs.
You think that she is mistaken and deluded, Christianity's teachings are wrong, and her happiness is based on mistaken beliefs.
Given all this, what does your phrase "happiness that comes from having mistaken beliefs isn't valuable" mean in this context?
I read your entire discussion the TheOtherDave and everyone else before replying. He said pretty much everything I would have said in these replies.
Reading further through the discussion I found this statement by you:
...Consider a medieval European society where life is nasty, brutal, and short, not to mention muddy and itchy. But on Sundays you go to the cathedral, a beautiful building with awe-inspiring stained glass windows and open your heart to unconditional love, forgiveness, and promise of eternal happiness. It makes life worth living -- but, sorry,
I was browsing my RSS feed, as one does, and came across a New York Times article, "A Village With the Numbers, Not the Image, of the Poorest Place", about the Satmar Hasidic Jews of Kiryas Joel (NY).
Their interest lies in their extraordinarily high birthrate & population growth, and their poverty - which are connected. From the article:
From Wikipedia:
Robin Hanson has argued that uploaded/emulated minds will establish a new Malthusian/Darwinian equilibrium in "IF UPLOADS COME FIRST: The crack of a future dawn" - an equilibrium in comparison to which our own economy will look like a delusive dreamtime of impossibly unfit and libertine behavior. The demographic transition will not last forever. But despite our own distaste for countless lives living at near-subsistence rather than our own extreme per-capita wealth (see the Repugnant Conclusion), those many lives will be happy ones (even amidst disaster).
So. Are the inhabitants of Kiryas Joel unhappy?
