For example, you think religious people don't value their happiness that comes from their religious beliefs? I would think that they do, very much so.
In the case of the "fictional refugees" that I mentioned earlier the person donating money to the conman certainly valued the happiness it gave him very much. But he was mistaken to value that happiness, because it came from a mistaken belief (namely, that the money he was giving the conman was benefiting refugees). It's possible to attach a mistaken value to something, if you hold mistaken beliefs about it.
There are some teachings of religion that are good things to follow regardless of whether or not you believe in the religion, these being basic moral lessons like "don't hurt people." But there are other teachings religions have that are only justified by the belief that there exists a supernatural creature who wants us to follow them, and we have a duty to obey that creature.
The lifestyle the people of Kiryas Joel lead is based on the second type of teachings. I explicitly think these teachings are wrong, that such a supernatural creature doesn't exist, and that we wouldn't necessarily be obligated to obey it if it did exist. If these precepts are false, than any happiness those people derive from their piety is based on mistaken beliefs.
Would you say that they all engage in denial?..... I am speaking of sincerely believing things which other people think are mistaken or wrong.
In that case it would be better to call their beliefs mistaken or deluded than in denial. But yes, I basically do believe that all religious beliefs are mistaken, deluded, or in denial. How could I believe otherwise without becoming religious myself?
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 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?
