Well, the 'Stargate Project' that he was involved in was shut down due to having 'No discernable benefit' - which seems to be one of the defining characteristics of most hocus-pocus type thinking.
There are mysteries in the universe and things that we don't understand. People can either fill in the blanks using their imaginations. - Which has been done for millennia with often very strange and fucked up consequences, or, people can gain an understanding of objective reality using some verifiable, repeatable, testable, methodological process (i.e. scientific method).
As far as I can tell, one approach consistently yields results, and the other doesn't. To a great extent, our success as a species relies on our ability to leverage objective reality to our advantage, so the more that we are able to understand it, the more capable we become.
The big problem with 'psychic powers' and so forth is that they have never been able to hold up to rigorous scientific inquiry (and not for lack of trying). - Making them not very useful in practice.
But, in the end, if you want magic, remember that there is no discernable difference between magic and sufficiently advanced technology. - After all, we don't need to worry about UFOs if we can make our own.
