This is the part that the materialists can't fully grasp. They don't get that their beloved empiricism is, itself, a limited and biased method of ascertaining truth. They get that everyone else's methods are limited and biased, and should be subjected to ongoing doubt and skepticism. But they don't get that their method is no better.
Care to substantiate any of that?
Empiricism is the only path to knowledge. You bristle at that, but cannot add anything that deserves to be called knowledge with this other way of knowing that you praise.
Lately, I've been seeing a lot of posts like yours telling skeptics how limited their "materialist" epistemology is, usually with some statement about seeing so much more through spiritual eyes. But they can never demonstrate any benefit to this other way of thinking, no spiritual truths gleaned, nothing that would appeal to the ones being told that they are missing out. Often we hear that evolution or science is in crisis as its wends its merry way forward revealing the secrets of reality.
Speaking of which, have you seen any of the work surrounding gravity waves? "Materialists" proposed that they existed, "materialists" built the LIGO gravitational wave detector, and "materialists" detected evidence for them confirming yet another scientific prophecy, science being in crisis notwithstanding.
In the meantime, the spiritualists and religionists have given the world no new knowledge in that time or at any time. Yet they sing the praises of their method of discerning "truth" while decrying the shortcomings of "materialism" and what others who are more empirical are unable to grasp. I might ask you now what you think we are unable to grasp, but I know that you won't have an answer. Why?
Because I've asked several RF posters over several years to comment on what they mean by spiritual, the spiritual realm, spirits and spiritual beings, and spiritual truths. They can't describe any of it or give examples of any spiritual truths. What should a skeptic conclude from that?
