 Ḥads was not just one more function to be added to the basket of terminologies used to explain psychological processes. Two applications in particular must be singled out. First of all, ḥads offered an analogy to prophecy; no other phenomenon from the world of humans, extraordinary as it may be, seemed as close to prophetic revelation. Second, it offered a way to account for great scientific acumen. Prophecy, scientific discovery, and intuition in general all lead those who experience them to certain knowledge in a moment of revelation, in general, knowledge that had not been available before.
