Is that a argument against the example I posted about the 'newer' experiences? If so, I agree.
We can make assumptions about what we might experience/discover based on what we have experienced, and reason dictates we must act on that basis, but we cannot ultimately be 100% certain about that. We can only be prepared to adjust our knowledge when faced with new experiences. What we cannot do is make assumptions without any basis at all.
But do we really have to know or prove that? Can't we just define it as something innate within human's? Would/could you also tie in conscience with this as well?
Of course we don't have to know and I am happy to say I don't know. Humans generally find that difficult to say. Perhaps because evolution has taught them that trying to find reasons, answers and predict things help them survive.
Re innate/conscience - I'm talking about what is the basis or underlying cause of what we experience. What caused the things we observe. We don't know. Maybe we will. Maybe we won't. We only know that we don't know.
The argument theist use is that since we don't know - then that means 'God did it' - that is nonsense and a baseless assumption. As I say we only know that we don't know.
