When we're talking about determining the truth or falsehood of claims about objective reality, and if we take "science" to mean rational inquiry generally and not just repeatable lab experiments, then yes.
However, you alluded to other foundations for knowledge; what are they? Could you give some examples?
We are getting into epistemology, and so I would ask how you are using 'knowledge.' If you define knowledge as only what is observable or testable, then only scientific knowledge will do. Relationships, appreciation of art, any sort of value or ethical system are based upon reason or logic with no 'objective' reality at the bottom, with perhaps the exception of 'utility.' However, 'it works' seems to fall a bit short of the whole human experience of what we think about and know.
I didn't say "good beliefs"; I talked about good reasons for beliefs.
OK, and you also appear to be saying that the only reasons you accept as good grounds for belief are those with a basis in the scientific method.
We're getting into epistemology: how do we know that we know what we know?
Greater minds than mine have debated the issue forever, so I doubt that we'll come to a resolution on it here, but the question remains: if you're making knowledge claims, even to yourself, how do you know that they're correct?
It still depends on what you mean by 'knowledge claims'.
As in relationships, the only 'knowledge claims' made by faith are subjective and experiential. Other than that, faith is trust and it incorporates the element of doubt.
She doesn't need to ask, because in behaving lovingly toward her, I already provide her with all the evidence she could ever want.
I'm sure she does know. She experiences your behavior toward her. But, from another person's POV, your loving actions might not be sufficient evidence of love. Some parents spank their kids out of love. Do they love their kids, or not?
I don't think that all aspects of God are necessarily testable, but if we're talking about a God whose concept is based on actual knowledge of him, then we're talking about a God that's testable to some degree.
You are using circular reasoning here, 9/10ths. God is if God is testable God is if ...
What if God is but God is not testable?
If a God-concept is the product of actual knowledge of God, then we can trace this concept back to its source. If a God-concept isn't the product of actual knowledge of God, then we're really just talking about something that was made up. If you're okay with having a fabricated God, that's up to you, but I personally wouldn't call such a thing a "God" at all.
We can trace our God-concept (and various other God-concepts) back to its source. That's what the Bible is, the story of a people's relationship with God. It is subjective and experiential and has developed over time.
Anyhow, it seems like we might be using different definitions for the term "God". When you say "God", what do you mean?
Anything I say will just lead us on a merry chase, because it is subjective. God is the Ground of Being, Creator and Sustainer, Love, More...
