I came across a post on Reddit that used the analogy of a homicide to describe differing attitudes towards knowledge in religious and religious people.
The analogy goes;
"Imagine you're a homicide detective. Most of the time you don't know who the killer is, so every piece of evidence is a valuable clue that might lead you to the truth and you are going to weigh it carefully.
But let's say on one case, you already know who the killer is, and all you're trying to do is gather enough evidence to convict. (Let's say you witnessed the crime firsthand, but your testimony is inadmissible for some reason.) Now your standard for evaluating evidence is completely different. You aren't trying to find out the truth—you already know it—you are just trying to find enough evidence to corroborate it.
In most things true believers are like the rest of us. They don't know the truth ahead of time and must rely on a critical evaluation of evidence to tease it out. But when it comes to religion, they think they already know the truth. They think they have witnessed firsthand the answers that everyone else is groping in the dark to find. So they aren't judging the church against the evidence for and against it. Rather, the evidence is judged according to whether it supports what they already know to be true."
In many ways this analogy is fantastic, because it gets at the disparity between faith and reason as forms of knowledge. But like all analogies, it fails in some areas, and I'd like to highlight two ways in which I think that happens, so as better to illuminate the phenomenon it is trying to describe.
1) We want to know why, or how, the detective thinks he knows who the killer is. Natural theology would say that he could have worked it out using the evidence, but eventually he would have to confront the killer and get a confession. Revealed theology would say that the evidence is insufficient and could be read in multiple ways, so the only way to know is to ask the killer directly and get them to explain how they committed the murder and how the evidence fits together. The only reason the detective knows this is because the killer approached him first and confessed.
If the detective witnessed the crime first hand we end up with a non-relational revealed theology, where the killer has no part in the transformation of the believer. Faith is therefore purely chance (the detective was just in the right place at the right time).
2) The post is written from the point of view of a non-religious person. The irony is that this person thinks they have the 'inside scoop' on how religious people think, or how faith really works. This doesn't mean the writer isn't correct, it's simply worth noting that he is not objective. He assumes that he (and people who hold his position) are able to weigh up the evidence.
a. If he thinks that no one did it and it was an accident then he would be an atheist, but his reasons for thinking this would need to be based on the evidence, and he would be claiming that he too has the inside scoop, in that everyone else thinks it's a murder but actually it wasn't. If everyone just studied the evidence then they'd realise that it was an accident and not a murder.
b. If he thinks the evidence is inconclusive he is an agnostic. He cannot simply ignore it and go home, because there is an answer to the homicide, whether it was an accident or there is a murderer still at large. Saying that the evidence is inconclusive and ignoring the issue does nothing to the reality of the situation. Instead, he must either continue weighing up the evidence until he reaches a conclusion, or try to get a confession from the killer himself. If the killer exists and is willing to confess (as one detective claims) then getting an answer should be pretty easy. If the killer cannot be singled out amongst a line up of suspects, then the detective cannot therefore conclude that the killer does not exist, only that if he exists he has not found him yet.
I hope that all this makes sense. I've tried to structure it to show my train of thought.
I think the big question for Revealed theology is why did the killer approach one detective and not another? There's no good answer for this, but Christianity unanimously argues that it is not because the detective is a good detective. Rather, the detective who knows is no different to detective who doesn't know. This might look a lot like chance, therefore looking like the non-relational revealed theology, and this is one of the criticisms often made of predestination. An Arminian might argue that once approached the detective has the choice whether or not to believe the killer, but again, the analogy starts to break down!
Criticism welcome!
