The concept of remote viewing, he says, still generates a healthy amount of skepticism (even in the choir) because its mechanisms are not yet understood. But a rich body of convincing data shows that psychic abilities exercised through "nonlocal mind" (our connection to universal mind) enable remote viewers "to experience and describe activities at distant places blocked from ordinary perception." The idea of nonlocality is derived from quantum-physics experiments showing that particles (photons) remain mysteriously connected even though traveling in opposite directions at the speed of light. CIA-sponsored remote-viewing experiments, many only recently declassified, were conducted by Targ and his colleagues at SRI as part of "ESPionage" during the Cold War.
The remarkable story behind the initial funding of this controversial research involves IONS' founder, Edgar Mitchell. The sequence of people and events has the aura of "nonlocal" connections at work. Targ, a popular speaker on psi phenomena, was lecturing on extrasensory perception at Grace Cathedral in San Francisco in 1972. In the audience was George Pezdirtz, a NASA administrator for special projects. Fascinated by Targ's lecture, Pezdirtz invited him to a NASA conference on speculative technology at St Simon's Island, North Carolina, in May 1972. There, Targ met the recently transformed Apollo astronaut Edgar Mitchell, who had experienced "a sense of universal connectedness" in space so powerful that it changed his life. Mitchell had just retired from the astronaut corps, and was envisioning a new organization dedicated to exploring the mysteries of consciousness. Also at the NASA meeting were science-fiction novelist Arthur C. Clarke, physicist Werner von Braun, and James Fletcher, Chief Administrator of NASA.
To this august gathering, Targ demonstrated his ESP teaching device that purports to help people improve their psychic functioning. He proposed a "distant effects" brain-wave experiment to test the hypothesis that, in one room, a person's EEG would change as a light flashed in a distant room. Further, he pitched the idea of a research program to investigate ways astronauts could hone their psychic abilities and consequently sharpen their interactions with complex spacecraft hardware.
