Interesting.
My own view is based on three assumptions ─ That a world exists external to me, that my senses are capable of informing of that world, and that reason is a valid tool. (They have to be assumptions since none of them can be demonstrated to be correct without first assuming it is indeed correct ─ an idea of Descartes, though his examples differ from mine.)
Nice. Pretty solid assumptions. Do you count yourself as a rationalist?
This more clearly distinguishes the world external to the self, and the role of the senses, than it seems to me Mr Hick does.
I also wonder how Mr Hick defines "real" and "reality". "Real" for me means having objective existence, found in nature, the world external to the self. Is he a mathematical Platonist who thinks 1, 2, 3, pi, e, i, have objective existence, are independent of human thought?
Hick was following in the British analytic tradition. So, no. He did not have any particular Platonic leanings. Nor do his ideas necessarily depend on a permanent or transcendent reality "beyond this one."
It should be pointed out that Hick did not think mystical experiences were "evidence of God"... He didn't think we could go around saying "God exists, because I experienced him."
In fact, it's best to forget the concept of God entirely when first approaching Hick's arguments concerning mysticism. Hick thought that
mystical experience is a rational basis for religious belief. This is subtly different from "mystical experiences are evidence of God (or some other religious phenomenon)." The former is less ambitious. Hick wasn't claiming evidence for anything.
Think of Thoreau, who spent two years in the woods. He developed an almost religious view of the natural objects around him.
"I experienced sometimes that the most sweet and tender, the most innocent and encouraging society may be found in any natural object... [A]fter I came to the woods, for an hour I doubted whether the near neighborhood of man was not essential to a serene and healthy life. To be alone was somewhat unpleasant. But in the midst of a gentle rain, while these thoughts prevailed, I was suddenly sensible of such sweet and beneficent society in Nature, in the very pattering of the drops, and in every sight and sound around my house, an infinite and unaccountable friendliness all at once, like an atmosphere, sustaining me, as made the fancied advantages of human neighborhood insignificant, and I have never thought of them since. Every little pine-needle expanded and swelled with sympathy and befriended me. I was so distinctly made aware of the presence of something kindred to me, that I thought no place could ever be strange to me again." --Thoreau.
Thoreau, I would argue, is having a
mystical experience of Walden Pond. His mystical account doesn't contradict a scientific account. All he sees are rocks, trees, and raindrops. An observer trained in science, using the scientific method would perceive the same phenomena. What makes Thoreau's observations religious is how he
interprets those phenomena.
"Hick’s pluralistic hypothesis is based on the notion that the world is religiously ambiguous, such that it can be experienced either religiously or non-religiously, with no compelling proofs for or against any one religious or nonreligious interpretation of the world."
Hick, John | Internet Encyclopedia of Philosophy
And we can get into what Hick's pluralistic hypothesis is if ya want. The point is, interpreting the world in a nonreligious way is just one way of understanding reality. Interpreting the world in a religious way does not add any axioms to your three. Nor does it contradict any of your axioms. So, does that mean you find such an interpretation reasonable?
Hick does. I'm not sure he's correct, but he makes a good argument.
