I’ve heard this objection a lot, actually. But do you think it’s really fair to compare Christian faith to belief in a leprechaun? Ours is a historical faith that has developed over thousands of years, with a practical theology that applies to everyone’s lives. A person naturally reacts quite differently to the belief that a supreme, loving being exists who created the universe compared to a magical creature that plays pranks on people.
Well, I think you’d agree that logically, the amount of time a belief has been around has nothing to do with how much evidence there is for it. The leprechaun example just makes that clear with an obviously ridiculous comparison, but the same comparison could just as easily be made to some other faith – for example, Vishnu has been worshipped for thousands of years, but there’s no evidence that he exists, either.
Also, just because different people hold different beliefs, why does that stop you from trying out one for yourself and seeing if it works like it says it will?
It doesn’t. What I was saying was that people of different faiths – that claim contradictory things – claim to have experiences that validate their faiths. Because their faiths make contradictory claims, they obviously can’t all be right about the experiences they report. For example, a Christian claims that Jesus is god, and a Hindu claims that there is some kind of Brahma force that manifests in several different gods (or something like that). The Christian thinks that he experiences the presence of Christ, and the Hindu thinks that he experiences the presence of Vishnu. They can’t both be correct.
Clearly, it’s possible to be mistaken about a spiritual experience you’ve had and/or fool yourself into thinking that a strong emotional experience is a spiritual experience. And clearly, this mistake or self-deluding is so strong that people can be convinced it’s the real thing. Given all of those facts, we have a good basis on which to discard personal experience as evidence for supernatural claims.
To look at those facts and then say, “Yeah, well, I’ll try out this religion, and if it produces ‘spiritual experience’ in me, then I’ll claim it’s real” is to utterly miss the point of what the evidence actually suggests.
But aren’t the logical arguments more in the form of proof by contradiction, rather than arguments from ignorance?
I may have mispoke. I meant something like this: take the argument from causes. The argument breaks down when you consider the fact that no one knows anything about the beginning of the universe – no one knows what came before the Big Bang or what the laws of the universe were like then (if, for example, causality even functioned then). The only actual answer is “we don’t know.”
That’s really the best I can do unless you want me to talk about a specific argument.
