Hi Steve,
I didn't mean to sidetrack your thread: please proceed...
Just one comment though, fwiw:
At the rational level, we no longer rely on 'revelation' from God as the more dependable source of information, but we rely more on reason, putting our beliefs to the test of rationality.
I was working on the theme of "wisdom and prophecy" in and around the Bible recently. What strikes me is the coexistence of opposite methodologies in the ancient world: wisdom did not look for supernatural "revelation"; it worked with observation and analysis of natural and cultural phenomena, deducing "laws" of causalities, warning about natural consequences of attitudes and behaviours, etc. At the same time prophecy tried to turn around the natural tools of wisdom, i.e. plain understanding of phenomena, to access supernatural revelation (through music- and dance-induced trances, sometimes drugs). The border between those two approaches was not exactly that between modern rationality and irrationality: wisdom acknowledged the existence of a divine realm, yet remote and mysterious; astrology or magic as occult "sciences" mostly fell on its side; it was waryof prophetism but respectful of its possibility -- cf. Plato's development on "god-given folly (mania)" in Phaedrus. Most Near-Eastern rulers had both wise men and prophets as counsellors, seeing them as complementary. There was room for both Apollo and Dionysos in Greek mythology.
Of course this particular equilibrium rested on a world vision which is no longer available to us. But it is noteworthy that the ancient world was not monolithic, and that there was always a (broadly) rationalistic approach to reality, along with others. The big (collective) paradigm shift imo came with the Enlightenment, which both reduced wisdom to reason and ruled out anything else as pathological and meaningless insanity (cf. Foucault's History of insanity in the classical age). But irrationality is still haunting the city of reason under many disguises, religious or other. (Hoping that some of the above may suit your topic.)
