Summary: I consider myself an open-minded person, but I tend to become itchy and skeptical when I encounter most books about the "unexplained"--there are just too many secret Soviet laboratories, mysterious disappearances (of the phenomena, and the investigators "and" data for that matter). And, I must admit, I've was somewhat skeptical of Sheldrake's previous books on "morphic resonance".
But being an open-minded person, I am glad when I can change my mind, and I am glad to report that this is a worthy book--because of its practicality. Sheldrake confronts some of the outstanding questions facing "PSIence"--and proposes level-headed experiments that readers themselves can become engaged in. Science has often made its greatest advances not when areas of the unknown were summarily dismissed--but when a proper balance between paradigm shifts and experimentation fell into place. It is conceivable that books such as this may help with the evolution of PSI to science.
