In some of my research for my dissertation, I've come across the idea of the presuppositions contained in each religion. Any system of belief, whether it be a religious belief of empirical scientific belief, forms the basis of what each person considers knowledge. Of course, if the belief is warranted or not, and thus counts as knowledge or not, is another matter. But I'm not dealing here with the question of whether the belief is warranted or not. Perhaps I'll save that for another post.
Anyway, the idea is that since each religion has these philosophical presuppositions about the nature of reality, the nature of knowledge, and the existence and nature of divine being(s), a religion is built upon the foundation of a philosophical worldview. That's nothing surprising, since all opinions are so – everything we think, we get from our philosophical worldview, the system that we build all of our new ideas out of, and into which we integrate new knowledge.
Josef Seifert is of the opinion, at least, that this means you can't separate the philosophical teaching about God (assuming you accept there is one) from the revealed teaching about God in the religion which builds upon the particular philosophical teaching – and vice versa, that if you follow a given philosophical teaching to its conclusion, and if it implies a religious teaching, you're intellectually obligated to follow through, as the teachings aren't really teaching different things.
Theologically seen, it's kind of like the idea of general revelation leading to specific revelation. The breaking point is usually that many Christian theologians would say that you can't jump the gap between the two, even if they do teach the same thing. There's no way of proving that they are, in fact, the same understanding of God. Some would even claim that they're not (but that's another post).
Is there a philosophical necessity that a given worldview must end in revealed religion? Given that there's absolute truth, is this the roots of an argument for exclusive religion based on which revealed religion fits the philosophical nature of the world best (well, an idea world in which we could all agree about the nature of it even outside of religious dispute)?
This seems to not only give us grounds for comparative theology outside of self-justifying claims of exclusivity in a religious doctrine, but also gives a pretty sharp impetus to take a long, hard look at the implicit epistemology and ontology of the West – because materialistic naturalism lives on borrowed foundations, and it borrows those foundations, along with its epistemic certainty, from Christian Theism. (I argue this second assertion in a forthcoming [hopefully] article, an update regarding the when and where will be posted assuming it gets published)
Comparative theology – not very politically correct, but obligatory?
