Well of course it is questionable,everything is
His point,the way I understand it anyway,is only that if these phenomenon occur,why
can`t we just research them properly and try and figure out what it is.Of course there are tons of pseudo psychics and what not out there.He merely points out that there are areas worth looking into properly,so we can get the topic out of the way and move on.
The problem is that materialist scientists won`t even look in his direction,of obvious reasons of course.Their whole body of knowledge and
work depends on these phenomena being false.If it is proven that they actually do occur in some way or another,the materialist house of cards will come crashing down to the ground.So they say its all a grand delusion.
The wisest thing to do here should be to get everyone in on this,do proper research and REALLY find out why these phenomena occur,so we can move on to something else,either with new knowledge in hand or a nail in the "psychic" coffin once and for all.
Something that will never happen by the way:) There is sadly no way that the scientific priesthood of materialism will ever agree to spend time on researching something that would destroy their system of belief. They have too much to lose in pursuing this kind of fringe science.
Personally I don`t believe in anything that is not proven,but he does have a good case for further investigation into these phenomenon.
