I know I’ve mentioned it before, but for the benefit of newer readers I would like to once again recommend the excellent blog Paranormalia, which presents the case for psi in a judicious, evenhanded, sensible, and often witty manner.
I’d also like to recommend the very expensive but indispensable book Irreducible Mind, by Kelly and Kelly et al. An excellent review of this groundbreaking book is found at the above-mentioned Paranormalia.
