But the soft sciences and religion are doing the same thing - except they do it with things like justice, love, anger, envy, lust etc. etc.
They tend to talk about these things as if they were as measurable as length or temperature.
Not really since empiricism (attempts to) take the question of the seer out of the the problem
So do psychology and religion.
I yet have to meet a religionist who wouldn't talk as if everything he or she says is the objective truth.
The practical norm for religionists is to make claims in the objective form, as if they wouldn't be made from an individual person's perspective.
means that we innately have the knowledge but it is currently in a covered state
All kinds of people are telling us what that "innate knowledge" supposedly is.
It comes down to having faith in those people, not in our own experiences.
It's not clear how the approach of religionists is any different than the approach of psychologists or sociologists:
Both will make claims formulated as "When you think/feel/say/do X, this means that you are/have Y" whereby they are the ones to determine when someone has X, not the person themselves.
All kinds of people are telling us "who we really are" and what our thoughts and feelings "really mean."
its not so much that the approach (to knowledge based claims) is similar but the notion of existing in a superior state (whether it be better health or liberation from nescience) is similar.
In some abstract, conceptual, nominal sense this is so.
But not in the practical sense, since religion, as well as psychology, also define what "better (mental) health" or "liberation from nescience" are - one doesn't have any actual, personal knowledge of either.
if its all about an artificial imposition then one tends to deviate from from the innate basis
That's merely a truism.
Of course, the Catholics have different ideas of what "an artificial imposition" and "innate basis" are than Muslims, and they yet different ones than Hindus and so on.
In the end, given all this variety, one comes away with the impression that our "innate basis" is merely a placeholder, a general ability, a potential, but not an actual set of qualities and skills ...
What could possibly be higher than sense data?
the context it operates in
That context is still something that is sensed - ie. just more sense data.
I am not sure how to answer that - I mean I am pretty sure I can find holes in whatever constants you would care to offer in regards to what a person can work with in order to assess the variables from doctors or plumbers.
Surely people can find holes in theistic claims too.
I think it all depends on how much one really wants something and how much one is prepared to sacrifice for it.
For instance if one really wants to get some plumbing fixed but really doesn't want to pay for it they run the risk of getting a dodgy job done.
Along similar lines, if one really wants to make spiritual advancement but abhors the concept of being taught anything (ie lacks humility) they will probably just carry around the knowledge of ten tons of spiritual texts like a donkey with a load of washing
You call it "lack of humility," I call it "refusal to be brainwashed" and "refusal to be fucked in the head."
With plumbing, one at least has some idea of what needs to be done and who could do it.
This is not the case with spiritual matters.
