Intro is fine. Though technically, 'proof' is stronger than evidence. So even if James fails to prove God's existence, he might still have shown they are evidence for God. I'm being a bit pedantic there but it's worth understanding and explaining that sort of distinction, especially when the terminology is in the essay question.
Intros just really need to say what you're going to argue, so that's fine.
Pretty good AO1 and a bit of AO2 with the strength.
Though it's a bit confusing when you say 'therefore we should trust Paul's story' - since that isn't your line of argument. Better to say 'therefore, Swinburne's argument suggests we should trust Paul's story'.
This is all fine AO1, though it's not very detailed. You've basically put different things together, James & Swinburne (with the illustration of Paul), and explained each of them a bit. But you're not demonstrating really deep understanding that way. Better to explain just one of them in a bit more detail and then evaluate that one.
See my notes about the way James builds an argument from his 4 criteria - I call it the 'pluralism' argument'.
You are mentioning James' argument which results from his being a 'pragmatist', which is the epistemological view that something being good for us is evidence of it's truth. That's why he'd regard Paul's experience being life-changing as evidence for it's authenticity. That's the kind of detail you need to start including if you want higher AO1 marks.
There's too many different things going on here. Better to separate James and Swinburne rather than trying to evaluate both of them at once.
Your chain of reasoning is:
St Paul's experience being life-changing doesn't mean it's evidence for God.
People can have a life-changing experience which wasn't real
E.g. St Theresa of Avila - who had psychological / medical issues,
Russell argues those can cause supposedly religious experiences
Swinburne admits we shouldn't trust people's experience if we have a valid reason to doubt them
We do have reason to doubt Avila, so her experience isn't valid evidence for God.
The problems are:
By the end of the evaluation, you've forgotten about James. You need to say 'therefore, the life-changing effects of an experience are not evidence for their having a supernatural origin'.
Also, you haven't really criticised Swinburne's view here. Yes, Swinburne might agree that Avila should be dismissed because we have a reason not to believe her. But, Swinburne's whole point is that there are people who have religious experiences for whom we have no such evidence of naturalistic explanations like illness. His argument is, we have no basis on which to avoid accepting
their experiences as evidence for God. You've not discredited that argument, which you'd need to do to justify your line of argument.
So, don't try to explain and evaluate two different arguments at once. It can be done better if you'd not made those mistakes and written more, but there's no advantage to it.
It's better to choose one criticism and develop that in detail, rather than trying to spray multiple criticisms against something. It can seem strong to throw multiple criticisms and have many reasons to disagree with something. But you get AO2 marks for the 'detail', 'coherence' and 'development' of your evaluation. So, it's better to choose one criticism and evaluate that.
James isn't really adding much. Sure, James wouldn't accept this experience as a valid mystical experience. But so what? Is James right..? You've not really addressed whether he's correct in his categorisation of religious experiences. So you're just saying James disagrees, which isn't evaluation.
I would go with the peer pressure example. I like adding Hume to that, that makes sense. Technically Hume was saying that about miracles but you could say it works against religious experiences too. See my notes for ways to explain the whole psychological dynamics involved in peer pressure / social compliance in more impressive detail.
Using Otto is fine, but you haven't evaluated him properly, you just say there's no concrete evidence.
The whole discussion about whether Otto would consider the toronto blessing a genuine religious experience is a bit superficial, because again who cares if Otto thinks it is! If you want to get into the question of whose criteria are valid, you need to debate and evaluate that, not merely identify what would be valid according to whose criteria. That's not evaluating who is right.
It's easier to just debate the validity of their arguments for religious exprience rather than debating their criteria honestly. Otto was influenced by Schliermacher to argue that religious experiences were self-authenticating, appreciated by the non-rational part of the mind etc - you need to then argue that makes no sense because it could be deluded by hallucination or something like that, or perhaps use Persinger's God helmet.
But really i would just get rid of Otto, and have three paragraphs - James, Swinburne and Corporate experiences - all individually explains and evaluated.
Anyway, this essay would get around a high B grade, perhaps something like 28/40.
It's fine, everything you mention is correct and relevant. But you would most benefit from being stricter with your structure.
A paragraph should be like this:
point (an argument for or against the question - can often be detailed AO1. If the question focuses on a particular area/scholar - which this one doesn't - then you must start your essay with the point of the first paragraph covering much of the AO1 for that thing)
counter (
one argument
directly countering the argument made in the 'point' section
evaluation (
Your judgement about whether the counter succeeded or not. Use language like 'X argument was un/successful because....' when starting your evaluation, or 'X fails because....' or 'However, X is invalid because...'
Make it just one argument per stage of the paragraph.
One argument for the point,
one direct counter to it,
one evaluation of that counter.
This is harder, because it means that those single arguments have to be made in more impressive and precise detail. But that's the most reliable way to get higher marks!
