The Maverick Philosopher has a great summary of thought regarding the essence of religion. Some of what he says ties in beautifully with the notion of an unseen moral order. He quotes William James, who was a world famous philosopher of the late 19th century.
Here are his points regarding the essence of religion:
“1. The belief that there is what William James calls an “unseen order.” (Varieties of Religious Experience, p. 53) This is a realm of absolute reality that lies beyond the perception of the five outer senses and their instrumental extensions. It is also inaccessible to inner sense or introspection. It is also not a realm of mere abstracta or thought-contents. So it lies beyond the discursive intellect. It is accessible from our side via mystical and religious experience. An initiative from its side is not to be ruled out in the form of revelation.
2. The belief that there is a supreme good for humans and that “our supreme good lies in harmoniously adjusting ourselves” to the “unseen order.” (Varieties, p. 53)
3. The conviction that we are morally deficient, and that this deficiency impedes our adjustment to the unseen order. Man is in some some sense fallen from the moral height at which he would have ready access to the unseen order. His moral corruption, however it came about, has noetic consequences.
4. The conviction that our moral deficiency cannot be made sufficiently good by our own efforts to afford us ready access to the unseen order.
5. The conviction that adjustment to the unseen order requires moral purification/transformation.
6. The conviction that help from the side of the unseen order is available to bring about this purification and adjustment.
7. The conviction that the sensible order is not plenary in point of reality or value, that it is ontologically and axiologically derivative. It is a manifestation or emanation or creation of the unseen order.”
