kosst,
The way things are done in a civilized conversation don't necessitate having to prove what is empirically perceived. I see, hear, touch, taste and smell things all day long and need no one to tell me what is real or imagined. Isn't that was phenomenology is about?
"an approach that concentrates on the study of consciousness and the objects of direct experience."
That sounds a lot like what we do when we hear the differences that a fuse can make.
As for a "body of evidence", how about the many tens of thousands who've tried it, hear it, and enjoy it? How do you discount that? Do the marketing skills you have tell you they are all deceived?
Your example of a divine entity being believed in for two, opposing reasons, one where it represents those who believe in fuses for no good reason, and to be discounted, and the other, where the body of evidence amounts to a domino theory which you say represents your side and is to be believed in is a head scratcher.
One takes a leap of faith, the other can be directly observed, over and over, by anyone who cares to try.
All the best,
Nonoise
