@ACB,
Quote:The difficulty with spiritual beliefs is that they come in many varieties, and some may contradict others. How are we to sort the (possibly) true from the false? In science, theories are tested by experiment; what equivalent method is there for testing spiritual beliefs? How can we make progress in ascertaining transcendental truths?
That is an excellent question. The key poin is that the laboratory for the testing of spiritual beliefs is within our own life and experience. In these disciplines, you are that which you seek to know. But like with science, you can only find out what works by experience and experiment. So you have to investigate, do the research, discover the methods, the premises, the promised results, then do the work, and see what happens.
This really was basic to Greek philosophy. If you read the meditations of Marcus Arelius and Plotinus (to name only two), they are based on
philosophy as a way of life, not just as a series of verbal formulations.
Furthermore by undertaking the effort of investigating which philosophical method is really worth pursuing, you are already doing the work of sorting out what, in your judgement, really are the philosophical methods that ought to be pursued. So by doing this, you are no longer dealing with the question purely in the abstract.
This is something well understood in the true and great traditions of philosophy, but not in the modern secular worldview, called the
Scientia Sacra, the sacred science. This is not a quaint belief amongst pre-modern people, it's the real deal.
