This accords with modern skepticism. W.K.Clifford admonishes us to rely on facts in our beliefs, which facts are proportionate to the level of need for evidence. Despite that non-pragmatist William James and Ward Keith, that does not keep us in bed;no, we act on that level of need. Some claims require no evidence. Some require extraordinary evidence as does creationism or theism in general.
Alvin Plantinga's God as a basic idea is lower than the first one,for it rests not only on no support but in contradiction to our conservation -background- of knowledge as God denotes intent whilst, as the teleonomic argument notes, science finds no divine intent so that Plantinga would ignorce science for his argument from ignorance!
