Suppose you have a occult theory of the world that tries to explain certain observations with its own words and structuring of the universe. It may be outdated and its system doesn't fit every observation we made since. But still, if there is some inherent structure we can exploit this system to get another view and new ideas that we then can try to formulate in a modern way. That supposed occult theory can lead to new hypotheses that we can test / try to falsify. Maybe this isn't fruitful, but it certainly could be.
