At the risk of bringing the discussion back to the thread topic, how does abandoning empiricism contribute to science? Can anyone give and example of a useful finding in science that depends for its authority, on personal revelation?
Perhaps you asked the question in too broad terms for your intent to denigrate spiritual revelation, but here are a couple or three examples of what you asked for as 'personal revelation' ... the creative 'aha' phenomenon is precisely personal revelation, personal perspective upon the universe which brings our instruction in body, soul, and spirit:
Watson and Crick imagining the double helix from their background research and the radiographic data of their lady colleague
The revelation/discovery of the benzene ring
Newton's conceptualization of gravity as the 'glue for holding the solar system together'
Einstein's special relativity revelation from the several concepts percolating his age (such as equations for frame of reference transformations)
Lister's concept of disease
... and there are many more one could cite. The point is, personal revelation is akin to spiritual awareness, both are based upon the accumulated learning of the mind (and stored and accessed via the brain for our current spacetime reality) which inspires the soul and enlivens the human spirit ... and in the case of scientific revelations, manifests in feedback phenomena we receive as scientific revelations regarding the nature of our universe of spacetime phenomena.
