To be clear, I am not defending beliefs that are contradicted by what we know about reality.
I am only questioning whether beliefs about what we don't know ought to be condemned.
And I am asking why beliefs about what we don't know ought to be considered valid at all. Because honestly, what's the difference between believing in gods and believing in unicorns or leprechauns? Why is one patently absurd and the other not?
The point was that they do have reasons for their belief, contrary to your statement.
And I'm questioning whether they are good reasons. Because again, the whole point is to get to truth. If that's not the point, then the whole process is meaningless.
It could be evidence that it is a healthy belief to have, despite there not being hard evidence for it.
Then it would also be evidence that taking heroin is healthy. We actually know how brain chemistry works. Women remain in abusive relationships for exactly the same reason that people remain religious. Are you going to argue that spousal abuse is healthy?
What evidence do you have that your life is worthwhile? But isn't it more beneficial to have that belief than not?
We're not talking about worthwhile, we're talking about true. In evolutionary terms, no individual human life is "worthwhile" because no single life actually contributes anything to the survival of the species.
I get your point: I am not saying that feeling good about something always indicates that it is true. I said it might be evidence, and that is all. People trust their gut in a lot of things when there is no clear cut answer.
The argument that people believe things for no good reason, which I think both of us agree with, doesn't make said belief a good thing. I get into these discussions all the time with theists, who invariably get to the point of "I'm going to believe anyhow, so there, pfffft!" That's not a mature or rational way to look at the world.
I wasn't really speaking of religion as a whole-- that is trickier since it's more likely to influence behavior.
Unfortunately, since beliefs inform actions, believing absurd things results in absurd actions. We look at religious violence and we find that, absent the beliefs, the violence would have no justification whatsoever. We look at religious parents who refuse to allow their children to see doctors, out of a belief that their god will heal them, that just results in lots of dead children. Without the beliefs, there is no reason to think those kids would be dead. We look at people who actively fight science because science contradicts their heartfelt beliefs. Take away the irrational beliefs and there's no reason for them to do so. I could go on and on and on.
I'm just talking about belief in the existence of a god.
Which is not supported by any objective evidence whatsoever.
I don't think such a belief is particularly irrational.
By definition it is. Irrational is defined as "not logical or reasonable." I'd love to see someone make a logical case for the factual existence of any specific god.
And if you are wrong about this belief, then so what? You were wrong. Nobody is going to punish you.
But you can harm a lot of people in the meantime. Besides all of the things I listed above, because, as I said, your beliefs inform your actions, your religion affects how you vote, how you treat others and how you raise your children, all of which has a demonstrable impact on society.
And say you are right to with-hold belief. Then so what? Nobody is handing out rewards for your rationality.
The benefits to society are all the reward anyone needs. Look at the Dark Ages, when religion was imprisoning anyone who didn't agree with their teaching and killing so-called heretics. Imagine where we might be today if there hadn't been hundreds of years of religious ignorance imposed upon the world. Imagine where the Middle East might be today without fundamentalist Islam. Ask the people who died on 9/11 what their lives have been like... oh wait, you can't do that, they're all dead because of religion.
