Can someone provide some actual examples of this form of evidence?
Just google 'How I Found God'. That should give you 136,000,000 examples or so.
2) Is subjective evidence limited to entities that can be empirically detected or not?
From my own understanding and looking at PD’s definitions, subjective and empirical are antonyms. Thus ‘subjective evidence’ is an oxymoron. However, if you are going to accept the joining of ‘subjective’ and ‘evidence’, then I don’t see why it wouldn’t apply to anything.
3) On what basis (aside from belief) is the cause of these subjective experiences attributed to supernatural entities rather than to fluctuations in the matrix, undetectable telepathic aliens manipulating our minds or any other conceivable cause of such things?
A misguided attempt to maintain credibility because, you know, god is more credible than, say, an alien.
4) Is belief itself a form of evidence on which we can justify belief?
This is what prompted me to respond. What about our belief that we make choices? What about the little engine that thought it could? Any martial artist will tell you that the first step to breaking the board or the brick is to believe that you can do it. A person’s self confidence is directly related to that person’s ability.
